    The spectrum of congenital heart disease (CHD) seen in the adult varies widely. Malformations range from mild anomalies requiring no intervention to extremely complex pathologies characterized by the presence of multiple coexistent defects. Echocardiography represents the primary noninvasive imaging modality in the assessment of these lesions. The transesophageal approach expands the applications of echocardiography by allowing the acquisition of anatomic and functional information that may not be obtainable by transthoracic imaging.

    Acyanotic heart disease constitutes a significant majority of patient who may present with non-cardiac symptoms. Either they are detected incidentally or present with respiratory complaints. Equipped with knowledge of anatomy by echocardiography and radiographic methods described in previous part of this presentation, diagnosis may be confidently attempted. On plain radiography acyanotic congenital heart diseases have variable appearance depending upon severity of disease. Cardiac size, chamber enlargement and pulmonary vascular pattern are key elements. Typically left to right shunts with large volume flow are associated with pulmonary plethora. Plain radiography has an important role in detecting manifestation of pulmonary arterial hypertension. Severe stenosis of pulmonary valve is associated with pulmonary oligemia. Small intra-cardiac shunts and anomalies of coronary arteries generally present with normal cardiac size and pulmonary arterial pattern. Disease spectrum presented in this illustration demands thorough scrutiny of pulmonary, osseous and abdominal abnormalities.

    Background: The rate of congenital heart disease is 0.8% in all live births. The majority of this, however, is acyanotic congenital heart disease. The survival rate of children with cardiac disease has increased with the developments provided in recent years and their lifetime is extended. Objectives: This study aims to evaluate neurodevelopment of children with uncomplicated acyanotic congenital heart disease in preschool period and determine the factors affecting their neurodevelopmental process. Patients and Methods: 132 children with acyanotic congenital heart disease aged 6 - 72 months were involved in the study. Mental development and intelligence levels of patients under 2 years old were assessed by using Bayley Development Scale-III, and Stanford Binet Intelligence test was employed for patients over 2 years old. Denver Developmental Screening Test II was applied to all patients for their personal-social, fine motor, gross motor and language development. Results: The average age of patients (67 girls, 65 boys) included in the study was 35.2 ± 19.6 months. It was determined that there were subnormal mental level in 13 (10%) patients and at least one specific developmental disorder in 33 (25%) patients. Bayley Mental Development Scale score of patients who had received incubator care in perinatal period was found significantly low (88 ± 4.2) compared to those with no incubator care (93.17 ± 8.5) (P = 0.028). Low educational level of father was established to be linked with low mental development scores at the age of 2 and following that age (P < 0.05). Iron deficiency anemia was discovered to be related to low psychometric test scores at every age (P < 0.05). Conclusions: Neurodevelopmental problems in children with acyanotic congenital heart disease were found higher compared to those in society. Mental development and intelligence levels of patients were determined to be closely associated with receiving incubator care, father’s educational level and

    Congenital complete heart block in utero has become diagnosed more frequently with the clinical use of fetal echocardiography. The fetus with complete heart block may remain asymptomatic or may develop congestive heart failure. Congenital complete heart block is more frequently seen in infants of mothers with systemic lupus erythematosus, both clinically manifested and subclinical systemic lupus erythematosus with positive antibodies (SS-A and SS-B antibodies). At birth, the neonate with complete heart block may remain asymptomatic and may not require a pacemaker to increase the heart rate. The indications for a pacemaker in neonates with complete heart block have been discussed. Both in-utero and neonatal management of congenital complete heart block are discussed to manage congestive heart failure in a fetus. Four patients with congenital complete heart block are presented covering a broad spectrum of clinical presentation, diagnosis, and management both in the fetal and neonatal period.

    Congenital heart defect (CHD) is the most common birth defect & a significant cause of childhood morbidity & mortality. Structural brain abnormalities are more common in children with CHD than general population. This study details the cognitive, motor and behavioral development of a child with congenital heart disease who is on medical management. In this retrospective descriptive study, abnormalities in neurobehavioral status of infant & children (6-42 months of age) with CHD, who are on medical management were assessed by a standardized neurobehavioral assessment test, BSID-II. Fifty-eight children were included, who were diagnosed as a case of congenital heart disease & confirmed by Colour Doppler echocardiography in the Paediatric Cardiology Department of Bangabandhu Sheikh Mujib Medical University, Bangladesh. Mean age of the children was 23±13 months (range, 6 to 42 months); M:F = 1:1.9. Among them 22(37.9%) had cyanotic and 36(62.1%) had acyanotic congenital heart disease. Neurobehavioral and neurologic abnormalities were documented in a significant number of children. BSID-II showed 23(39.7%) had delayed metal development, 24(41.4%) had motor impairment and 16(27.6%) had non-optimal behavioral performance. Interestingly, infant and young children with acyanotic congenital heart defects were more likely to demonstrate severe neurologic compromise than were those with cyanotic defects. Findings of this study suggest that the prevalence of neurobehavioral abnormalities in infants and young children with congenital heart defects has been under predicted & indicates that delay in closure (surgery/device) puts the patient at an increased risk of neuro-developmental insult.

    BACKGROUND: Gastrointestinal symptoms are a common feature in infants with congenital heart disease. AIM: This study was designed to evaluate age-dependent serum levels of antigliadin antibodies among malnourished Egyptian infants with congenital heart disease (CHD) and gastrointestinal symptoms. SUBJECTS AND METHODS: This case-control study conducted on 60 infants with established congenital heart disease. They were subdivided into cyanotic and acyanotic groups, and each group includes 30 patients compared with thirty apparently healthy infants of matched age, sex, and social class. Serum antigliadin antibodies levels were measured using ELISA. RESULTS: The mean age of introduction of cereals in the diet and appearance of gastrointestinal symptoms were six months. On comparison with controls, patients showed highly significant higher serum levels of antigliadin antibodies (P < 0.000). On analysing risk factors using odds ratio, the age at onset of GIT symptoms, diarrhoea, abdominal pain, and distension had been found to be significantly associated with high serum antigliadin antibodies among malnourished CHD infants with a prediction of 95%. CONCLUSION: Serum IgA, IgM, and IgG class antibodies to gliadin play a significant role in the pathogenesis of malnutrition in infants with CHD. Gluten containing foods should never be introduced before the end of the six months. PMID:28293318

    Are there gender differences in prevalence, surgical results and long-term survival of patients with congenital heart disease? Available literature data allow us to state what follows. At birth there is a mild but significant prevalence of congenital heart disease in females. The most severe congenital heart diseases are less frequent in girls, but when they are present in females, they are linked to a higher surgical mortality rate, due perhaps to lower weight at birth and to the prevalence of extracardiac malformations and/or of associated genetic syndromes. On the other hand, in adults, surgery for congenital heart disease is at higher risk in males, and so the long-term survival rate is higher in females. Particular psychological attitudes, a higher incidence of pulmonary hypertension, as well as specific problems linked to the reproductive function characterize congenital heart disease in adult women. The knowledge and analysis of these data are essential for a correct management of congenital heart disease in neonates, children and adults.

    Summary Introduction Echocardiographic evaluation remains the gold standard for the diagnosis of structural cardiac disease. No previous prospective studies have been done on the prevalence of congenital heart disease (CHD) in the Niger Delta area. This study was done to determine the frequency and pattern of congenital heart disease, using echocardiography as a diagnostic tool. Methods All patients presenting to the Paediatric Cardiology clinics of two centres, the University of Port Harcourt Teaching Hospital and the Paediatric Care Hospital between April 2009 and March 2013, were recruited and all had echocardiography performed. Results Prevalence of CHD in this study was 14.4 per 1 000 children; 277 (83.4%) of the patients had acyanotic CHD and 55 (16.6%) had cyanotic CHD. Ventricular septal defect and tetralogy of Fallot were the commonest acyanotic and cyanotic heart defects, respectively Conclusion The high prevalence of CHD in this study is the highest in the country and Africa, and may be attributable to the increased oil spillage and gas flaring from petroleum exploitation in this region.

    Cardiovascular malformations are the most common type of birth defect and result in significant mortality worldwide. The etiology for the majority of these anomalies remains unknown but genetic factors are being recognized as playing an increasingly important role. Advances in our molecular understanding of normal heart development have led to the identification of numerous genes necessary for cardiac morphogenesis. This work has aided the discovery of an increasing number of monogenic causes of human cardiovascular malformations. More recently, studies have identified single nucleotide polymorphisms and submicroscopic copy number abnormalities as having a role in the pathogenesis of congenital heart disease. This review discusses these discoveries and summarizes our increasing understanding of the genetic basis of congenital heart disease. PMID:21532774

    The story of congenital heart disease is one of the major successes of medicine in the last 50 years. Heart conditions previously associated with early death are now successfully treated. Many of these women are now in their child-bearing years wishing to have children of their own. All of these women should be offered comprehensive pre-conception counselling by a dedicated multi-disciplinary team. Each woman will present a unique set of cardiac and obstetric challenges that require an individualised assessment of risk and a carefully documented care plan. In this chapter, I describe the most common forms of congenital heart disease and the specific issues that should be assessed before conception. I present a systematic approach to risk stratification and care planning. These lesions range from mild disease with little implications for pregnancy to those with a sizable risk of maternal mortality or complications. I will also discuss fetal risk factors.

    Patients with complex congenital heart disease are at risk for neurodevelopmental impairments. Evidence suggests that brain maturation can be delayed and pre- and postoperative brain injury may occur, and there is limited information on the long-term effect of congenital heart disease on brain development and function in adolescent patients. At a mean age of 13.8 years, 39 adolescent survivors of childhood cardiopulmonary bypass surgery with no structural brain lesions evident through conventional cerebral magnetic resonance imaging and 32 healthy control subjects underwent extensive neurodevelopmental assessment and cerebral magnetic resonance imaging. Cerebral scans were analysed quantitatively using surface-based and voxel-based morphometry. Compared with control subjects, patients had lower total brain (P = 0.003), white matter (P = 0.004) and cortical grey matter (P = 0.005) volumes, whereas cerebrospinal fluid volumes were not different. Regional brain volume reduction ranged from 5.3% (cortical grey matter) to 11% (corpus callosum). Adolescents with cyanotic heart disease showed more brain volume loss than those with acyanotic heart disease, particularly in the white matter, thalami, hippocampi and corpus callosum (all P-values < 0.05). Brain volume reduction correlated significantly with cognitive, motor and executive functions (grey matter: P < 0.05, white matter: P < 0.01). Our findings suggest that there are long-lasting cerebral changes in adolescent survivors of cardiopulmonary bypass surgery for congenital heart disease and that these changes are associated with functional outcome.

    Heart failure (HF) in adult congenital heart disease (ACHD) is vastly different to that observed in acquired heart disease. Unlike acquired HF in which pharmacological strategies are the cornerstone for protecting and improving ventricular function, ACHD-related HF relies heavily upon structural and other interventions to achieve these aims. patients with ACHD constitute a small percentage of the total adult heart transplant population (∼3%), although the number of ACHD heart transplant recipients is growing rapidly with a 40% increase over the last two decades. The worldwide experience to date has confirmed heart transplantation as an effective life-extending treatment option in carefully selected patients with ACHD with end-stage cardiac disease. Opportunities for improving outcomes in patients with ACHD-related HF include (i) earlier recognition and referral to centres with combined expertise in ACHD and HF, (ii) increased awareness of arrhythmia and sudden cardiac death risk in this population, (iii) greater collaboration between HF and ACHD specialists at the time of heart transplant assessment, (iv) expert surgical planning to reduce ischaemic time and bleeding risk at the time of transplant, (v) tailored immunosuppression in the post-transplant period and (vi) development and validation of ACHD-specific risk scores to predict mortality and guide patient selection. The purpose of this article is to review current approaches to diagnosing and treating advanced HF in patients with ACHD including indications, contraindications and clinical outcomes after heart transplantation.

    AIM—Research into intellectual impairment among children with congenital heart disease has focused mainly on older children. This study was designed to determine whether previous findings are applicable to preschool children.
METHODS—Three groups of children under 31/2 years old were assessed immediately before treatment and 12 months later: a group with congenital heart disease awaiting surgery, another awaiting bone marrow transplantation, and a healthy comparison group.
RESULTS—Although the means of the three groups were within the normal range, preoperatively the cardiac and transplant groups showed deficits compared with the healthy controls. Postoperatively, continuing developmental deficits were significant only in the children with cyanotic lesions.
CONCLUSIONS—Conclusions about intellectual development in older children with congenital heart disease do not apply to preschool children. Before corrective surgery, chronic illness itself appears to be the predominant influence on development. Postoperatively, cyanotic and acyanotic lesions are associated with different short term outcomes.

    Congenital heart disease is the most common congenital disorder in newborns. Advances in cardiovascular medicine and surgery have enabled most patients to reach adulthood. Unfortunately, prolonged survival has been achieved at a cost, as many patients suffer late complications, of which heart failure and arrhythmias are the most prominent. Accordingly, these patients need frequent follow-up by physicians with specific knowledge in the field of congenital heart disease. However, planning of care for this population is difficult, because the number of patients currently living with congenital heart disease is difficult to measure. Birth prevalence estimates vary widely according to different studies, and survival rates have not been well recorded. Consequently, the prevalence of congenital heart disease is unclear, with estimates exceeding the number of patients currently seen in cardiology clinics. New developments continue to influence the size of the population of patients with congenital heart disease. Prenatal screening has led to increased rates of termination of pregnancy. Improved management of complications has changed the time and mode of death caused by congenital heart disease. Several genetic and environmental factors have been shown to be involved in the etiology of congenital heart disease, although this knowledge has not yet led to the implementation of preventative measures. In this Review, we give an overview of the etiology, birth prevalence, current prevalence, mortality, and complications of congenital heart disease.

    The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society.

    With the advances in congenital cardiac surgery and postoperative care, an increasing number of children with complex congenital heart disease now reach adulthood. There are already more adults than children living with a congenital heart defect, including patients with complex congenital heart defects. Among these adults with congenital heart disease, a significant number will develop ventricular dysfunction over time. Heart failure accounts for 26-42% of deaths in adults with congenital heart defects. Heart transplantation, or heart-lung transplantation in Eisenmenger syndrome, then becomes the ultimate therapeutic possibility for these patients. This population is deemed to be at high risk of mortality after heart transplantation, although their long-term survival is similar to that of patients transplanted for other reasons. Indeed, heart transplantation in adults with congenital heart disease is often challenging, because of several potential problems: complex cardiac and vascular anatomy, multiple previous palliative and corrective surgeries, and effects on other organs (kidney, liver, lungs) of long-standing cardiac dysfunction or cyanosis, with frequent elevation of pulmonary vascular resistance. In this review, we focus on the specific problems relating to heart and heart-lung transplantation in this population, revisit the indications/contraindications, and update the long-term outcomes.

    Congenital heart defects represent the most common malformation at birth, occurring also in ∼50% of individuals with Down syndrome. Congenital heart defects are thought to have multifactorial etiology, but the main causes are largely unknown. We have explored the global methylation profile of fetal heart DNA in comparison to blood DNA from control subjects: an absolute correlation with the type of tissue was detected. Pathway analysis revealed a significant enrichment of differential methylation at genes related to muscle contraction and cardiomyopathies in the developing heart DNA. We have also searched for abnormal methylation profiles on developing heart-tissue DNA of syndromic and non-syndromic congenital heart defects. On average, 3 regions with aberrant methylation were detected per sample and 18 regions were found differentially methylated between groups. Several epimutations were detected in candidate genes involved in growth regulation, apoptosis and folate pathway. A likely pathogenic hypermethylation of several intragenic sites at the MSX1 gene, involved in outflow tract morphogenesis, was found in a fetus with isolated heart malformation. In addition, hypermethylation of the GATA4 gene was present in fetuses with Down syndrome with or without congenital heart defects, as well as in fetuses with isolated heart malformations. Expression deregulation of the abnormally methylated genes was detected. Our data indicate that epigenetic alterations of relevant genes are present in developing heart DNA in fetuses with both isolated and syndromic heart malformations. These epimutations likely contribute to the pathogenesis of the malformation by cis-acting effects on gene expression.

    Injury to the myocardium disrupts geometric integrity and results in changes to intracardiac pressure, wall stress and tension, and the pattern of blood flow through the heart. Significant disruption to pump function results in heart failure which is defined in terms of symptoms: breathlessness and fatigue, signs of salt and water retention, and neurohormonal activation. This syndrome most commonly occurs in the context of injury due to ischaemic heart disease and dilated cardiomyopathy but because patients with congenital heart disease (CHD) are born with sometimes gross distortions of cardiac anatomy they too are subject to the forces that drive heart failure. This paper explores the available data relating to the clinical and neurohormonal manifestations of heart failure in patients with congenital heart disease and describes how, by additionally exploring events at a cellular level, we may be able to arrive at a definition of heart failure relevant to this population.

    Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations. Assessment of adult congenital heart disease with imaging techniques can be as accurate as in children. However, these techniques cannot substitute for a detailed clinical assessment. Physical examination, electrocardiography and chest x-rays remain the three main pillars of bedside diagnosis. Transthoracic echocardiography is undoubtedly the imaging technique which provides most information, and in many situations no additional studies are needed. Nevertheless, ultrasound imaging properties in adults are not as favorable as in children, and prior surgical procedures further impair image quality. Despite recent advances in ultrasound technologies such as harmonic or contrast imaging, other diagnostic procedures are sometimes required. Fortunately, transesophageal echocardiography and magnetic resonance imaging are easily performed in the adult, and do not require anaesthetic support, in contrast to pediatric patients. These techniques, together with nuclear cardiology and cardiac catheterization, complete the second tier of diagnostic techniques for congenital heart disease. To avoid unnecessary repetition of diagnostic procedures, the attending cardiologist should choose the sequence of diagnostic techniques carefully; although the information this yields is often redundant, it is also frequently complementary. This article aims to compare the diagnostic utility of different imaging techniques in adult patients with congenital heart disease, both with and without prior surgical repair.

    There has been remarkable progress in understanding the genetic basis of cardiovascular malformations. Chromosome microarray analysis has provided a new tool to understand the genetic basis of syndromic cardiovascular malformations resulting from microdeletion or microduplication of genetic material, allowing the delineation of new syndromes. Improvements in sequencing technology have led to increasingly comprehensive testing for aortopathy, cardiomyopathy, single gene syndromic disorders, and Mendelian-inherited congenital heart disease. Understanding the genetic etiology for these disorders has improved their clinical recognition and management and led to new guidelines for treatment and family-based diagnosis and surveillance. These new discoveries have also expanded our understanding of the contribution of genetic variation, susceptibility alleles, and epigenetics to isolated congenital heart disease. This review summarizes the current understanding of the genetic basis of syndromic and non-syndromic congenital heart disease and highlights new diagnostic and management recommendations.

    Environmental factors such as ambient air pollution have been associated with congenital heart defects. The aim of this study was to investigate the association between gestational exposure to air pollution and the risk of congenital heart defects. We conducted a registry-based cohort study with a total of 135,527 live- and still-births in the Tel-Aviv region during 2000-2006. We used a Geographic Information System-based spatiotemporal approach with weekly inverse distance weighting modeling to evaluate associations between gestational exposure to ambient air pollution during weeks 3-8 of pregnancy and the risk for congenital heart defects. The following pollutants were studied: carbon monoxide, nitrogen-dioxide, ozone, sulfur-dioxide and particulate matter with aerodynamic diameter smaller than 10 μm and 2.5 μm (PM10, PM2.5 respectively). Logistic models, adjusted for socio-demographic covariates were used to evaluate the associations. We found that maternal exposure to increased concentrations of PM10 was associated with multiple congenital heart defects (adjusted OR 1.05, 95% CI: 1.01 to 1.10 for 10 μg/m(3) increment). An inverse association was observed between concentrations of PM2.5 and isolated patent ductus arteriosus (adjusted OR 0.78, 95% CI: 0.68 to 0.91 for 5 µg/m(3) increment). Sensitivity analyses showed that results were consistent. Generally there were no evidence for an association between gaseous air pollutants and congenital heart defects.Our results for PM10 and congenital heart defects confirm results from previous studies. The results for PM2.5 need further investigations.

    Introduction Congenital heart disease is an abnormality in the structure or cardiocirculatory function, occurring from birth, even if diagnosed later. It can result in intrauterine death in childhood or in adulthood. Accounted for 6% of infant deaths in Brazil in 2007. Objective To estimate underreporting in the prevalence of congenital heart disease in Brazil and its subtypes. Methods The calculations of prevalence were performed by applying coefficients, giving them function rates for calculations of health problems. The study makes an approach between the literature and the governmental registries. It was adopted an estimate of 9: 1000 births and prevalence rates for subtypes applied to births of 2010. Estimates of births with congenital heart disease were compared with the reports to the Ministry of Health and were studied by descriptive methods with the use of rates and coefficients represented in tables. Results The incidence in Brazil is 25,757 new cases/year, distributed in: North 2,758; Northeast 7,570; Southeast 10,112; South 3,329; and Midwest 1,987. In 2010, were reported to System of Live Birth Information of Ministry of Health 1,377 cases of babies with congenital heart disease, representing 5.3% of the estimated for Brazil. In the same period, the most common subtypes were: ventricular septal defect (7,498); atrial septal defect (4,693); persistent ductus arteriosus (2,490); pulmonary stenosis (1,431); tetralogy of Fallot (973); coarctation of the aorta (973); transposition of the great arteries (887); and aortic stenosis 630. The prevalence of congenital heart disease, for the year of 2009, was 675,495 children and adolescents and 552,092 adults. Conclusion In Brazil, there is underreporting in the prevalence of congenital heart disease, signaling the need for adjustments in the methodology of registration. PMID:26107454

    An 8-year-old, intact male Persian cat was presented with a prominent heart murmur, exercise intolerance, anorexia, and periodontitis. There was no cyanosis and no laboratory evidence for systemic hypoxemia. Echocardiography showed a dextropositioned aorta, moderate pulmonic stenosis (maximal velocity 4.06 m/s), ventricular septal defect, and right ventricular hypertrophy. The shunt direction was predominantly left-to-right in systole and minimally right-to-left in diastole. The cat was diagnosed with acyanotic (pink) tetralogy of Fallot and was managed medically with atenolol. PMID:27247457

    Most women with known congenital heart disease can have successful pregnancy, labor, and delivery. Preconception assessment is essential in understanding anatomy, repairs, and current physiology, all of which can influence risk in pregnancy. With that foundation, a multidisciplinary cardio-obstetric team can predict and prepare for complications that may occur with superimposed hemodynamic changes of pregnancy. Individuals with Eisenmenger syndrome, pulmonary hypertension, cyanosis, significant left heart obstruction, ventricular dysfunction, or prior major cardiac event are among the highest risk for complications.

    Congenital heart disease is the most frequently occurring congenital disorder affecting ≈0.8% of live births. Thanks to great efforts and technical improvements, including the development of cardiopulmonary bypass in the 1950s, large-scale repair in these patients became possible, with subsequent dramatic reduction in morbidity and mortality. The ongoing search for progress and the growing understanding of the cardiovascular system and its pathophysiology refined all aspects of care for these patients. As a consequence, survival further increased over the past decades, and a new group of patients, those who survived congenital heart disease into adulthood, emerged. However, a large range of complications raised at the horizon as arrhythmias, endocarditis, pulmonary hypertension, and heart failure, and the need for additional treatment became clear. Technical solutions were sought in perfection and creation of new surgical techniques by developing catheter-based interventions, with elimination of open heart surgery and new electronic devices enabling, for example, multisite pacing and implantation of internal cardiac defibrillators to prevent sudden death. Over time, many pharmaceutical studies were conducted, changing clinical treatment slowly toward evidence-based care, although results were often limited by low numbers and clinical heterogeneity. More attention has been given to secondary issues like sports participation, pregnancy, work, and social-related difficulties. The relevance of these issues was already recognized in the 1970s when the need for specialized centers with multidisciplinary teams was proclaimed. Finally, research has become incorporated in care. Results of intervention studies and registries increased the knowledge on epidemiology of adults with congenital heart disease and their complications during life, and at the end, several guidelines became easily accessible, guiding physicians to deliver care appropriately.

    Cardiac development is a dynamic process regulated by spatial and temporal cues that are integrated to effect molecular, cellular, and tissue-level events that form the adult heart. Disruption of these highly orchestrated events can be devastating for cardiac form and function. Aberrations in heart development result in congenital heart defects (CHDs), which affect 1 in 100 infants in the United States each year. Zebrafish have proven informative as a model organism to understand both heart development and the mechanisms associated with CHDs due to the similarities in heart morphogenesis among vertebrates, as well as their genetic tractability and amenability to live imaging. In this review, we discuss the mechanisms of zebrafish heart development and the utility of zebrafish for understanding syndromic CHDs, those cardiac abnormalities that occur in the context of multisystem disorders. We conclude with avenues of zebrafish research that will potentially inform future therapeutic approaches for the treatment of CHDs.

    Platelet microparticles (PMPs) and function profile in children with congenital heart disease (CHD) have not been widely explored. We investigated platelet aggregation, flow cytometric platelet surface receptors (P-selectin and glycoprotein (GP) IIb/IIIa) and PMPs in 23 children with cyanotic CHD (CCHD), 30 children with acyanotic CHD (ACHD) and 30 healthy controls correlating these variables to hematological and coagulation parameters including von Willebrand factor antigen (vWF Ag) as a marker of endothelial dysfunction. Hemoglobin, hematocrit (HCT), D-dimer, and vWF Ag were significantly higher in CCHD than ACHD group. Platelet MPs and P-selectin expression were increased in patients than controls, particularly in CCHD and positively correlated to HCT, D-dimer, and vWF Ag while platelet count, aggregation, and GP IIb/IIIa expression were decreased in CCHD compared with ACHD group and negatively correlated to HCT. The overproduction of PMPs and platelet activation with suppressed aggregation may be implicated in the pathogenesis of coagulation/hemostatic abnormalities in children with CCHD.

    Objectives Oral manifestations recorded for congenital heart disease (CHD) patients include teeth hypoplasia and high caries incidence. These observations suggested that the enamel and dentin of the teeth may be altered, increasing the risk for caries incidence. This study was designed to investigate the effect of CHD on the ultrastructure and composition of deciduous sound teeth. Methods Thirty sound exfoliated human deciduous incisor teeth were selected for this study. They were divided into three groups, Group I (control) from healthy children (n = 6), Group II from acyanotic CHD children (n = 12) and Group III from cyanotic CHD children (n = 12). Each tooth was longitudinally sectioned, providing enough specimens for ultrastructure and chemical analysis using ESEM/EDAX. The results of ESEM/EDAX and dentin image analysis were statistically analyzed using one-way ANOVA test followed by Tukey’s test. Results Enamel of groups II and III showed increased dissolution and irregular orientation of enamel prisms. Orifices of dentinal tubules demonstrated widening and irregular outlines, also lateral branching increased markedly. Image analysis of dentin ESEM photomicrographs showed a highly significant increase in surface area of dentinal tubules. Decrease in calcium (Ca) and phosphorus (P) levels was statistically significant (P < 0.05). Conclusion CHDs affect the structure and chemical composition of deciduous teeth. PMID:25243076

    Improved treatment options in paediatric cardiology and congenital heart surgery have resulted in an ageing population of patients with cyanotic congenital heart disease (CCHD). The risk of acquired heart disease such as atherosclerosis increases with age.Previous studies have speculated whether patients with CCHD are protected against atherosclerosis. Results have shown that the coronary arteries of patients with CCHD are free from plaques and stenosis. Decreased carotid intima-media thickness and low total plasma cholesterol may indicate a reduced risk of later development of atherosclerosis. However, the evidence is still sparse and questionable, and a reasonable explanation for the decreased risk of developing atherosclerosis in patients with CCHD is still missing.This review provides an overview of what is known about the prevalence and potential causes of the reduced risk of atherosclerosis in patients with CCHD.

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.

    Introduction: Congenital heart defects (CHDs) are an important cause of mortality and morbidity in children representing a major global health burden. It is thus important to determine their prevalence and spectrum and identify risk factors associated with the development of heart defects. Materials and Methods: A case-control study was carried out in the Department of Pediatrics and Center of Cardiology, Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India, from February 2014 to August 2015. All patients referred with complaints or clinical examination suggestive of CHDs were further evaluated with echocardiography. On Echocardiography, patients having CHDs were included as cases and those having a normal echocardiographic study were included as controls. Healthy controls were also included. 400 cases and 400 controls were thus identified; preterms having patent ductus arteriosus and patent foramen ovale and those with acquired heart defects were excluded. Risk factors among cases and controls were further studied. Results: Acyanotic heart defects were 290 (72.50%) of the total heart defects, whereas the contribution of cyanotic heart defects was 110 (27.50%). Out of all CHDs, ventricular septal defect was the most common lesion with contribution of 152 (38%) cases, whereas among the cyanotic heart defects, Tetralogy of Fallot was the most common lesion (18% of total cases). Out of the total 400 cases, 261 were males (65.25%). On univariate analysis, paternal age (odds ratio, OR, 2.01), bad obstetric history (OR, 2.65), antenatal febrile illness (OR, 4.12), and advanced maternal age (OR, 3.28) were found to increase the risk of CHD whereas intake of multivitamin (OR, 3.02) was found to be protective. The risk factors were further analyzed with multivariate logistic regression analysis and all the above factors were found to be significantly associated. Conclusion: We noted that the profile of CHD in our population was similar

    PubMed

    2013-05-01

    Although the incidence of congenital heart disease (CHD) is similar worldwide, the burden of supporting these patients falls more heavily on countries with high fertility rates. In a country with a fertility rate of about eight per woman, the population has to support four times as many children with CHD as in a country with a fertility rate of two. Countries with the highest fertility rates tend to have the lowest incomes per capita, thus accentuating the disparity. Countries with high fertility rates have more children with congenital heart disease per wage earner. Improving local health services and controlling infectious diseases (diarrhoeal illness, rheumatic fever, measles, rotoviral infection) are important but are mere 'band-aids' compared to improving education, empowering women and reducing birth rates.

    Heart transplantation has become an increasingly common and effective therapy for adults with end-stage congenital heart disease (CHD) because of advances in patient selection and surgical technique. Indications for transplantation in CHD are similar to other forms of heart failure. Pretransplant assessment of CHD patients emphasizes evaluation of cardiac anatomy, pulmonary vascular disease, allosensitization, hepatic dysfunction, and neuropsychiatric status. CHD patients experience longer waitlist times and higher waitlist mortality than other transplant candidates. Adult CHD patients undergoing transplantation carry an early hazard for mortality compared with non-CHD recipients, but by 10 years posttransplant, CHD patients have a slight actuarial survival advantage.

It offers significant advantages over other CHD imaging modalities and techniques: no ionizing radiation; ability to be run free-breathing; ECG-gated dual-phase imaging for accurate measurements and tissue properties estimation; and higher signal-to-noise ratio and isotropic voxel resolution for multiplanar reformatting assessment. However, there are limitations, such as potentially long acquisition times with image quality degradation.

    Congenital heart disease is the most common congenital anomaly, representing an important cause of infant morbidity and mortality. Congenital heart disease represents a group of heart anomalies that include septal defects, valve defects, and outflow tract anomalies. The exact genetic, epigenetic, or environmental basis of congenital heart disease remains poorly understood, although the exact mechanism is likely multifactorial. However, the development of new technologies including copy number variants, single-nucleotide polymorphism, next-generation sequencing are accelerating the detection of genetic causes of heart anomalies. Recent studies suggest a role of small non-coding RNAs, micro RNA, in congenital heart disease. The recently described epigenetic factors have also been found to contribute to cardiac morphogenesis. In this review, we present past and recent genetic discoveries in congenital heart disease.

    Heart diseases are the leading cause of maternal morbidity and mortality. The number of patients with congenital heart diseases reaching childbearing age, as well as the proportion of women with acquired conditions, such as ischemic heart disease, becoming pregnant is constantly increasing. All women with known heart disease should have pre-pregnancy counseling, to assess maternal and fetal risk. Women at moderate or high risk should be under the care of a specialist prenatal team with experience in managing women with heart disease during pregnancy. Conditions that are considered at particularly high risk (mortality >10%) include Marfan syndrome with dilated aortic root, severe left ventricular dysfunction, severe left heart obstructive lesions, and pulmonary hypertension. Peripartum cardiomyopathy is a rare and potentially fatal disease related to pregnancy and the postnatal period that presents with symptoms of congestion and/or hypoperfusion and may rapidly progress to acute and life-threatening heart failure. However, the majority of women with heart disease can tolerate pregnancy; therefore an adequate multidisciplinary approach with the gynecologist, anesthesiologist and cardiologist should be advocated in order to reduce maternal and fetal risks associated with pregnancy.

    This article reviews the changing epidemiology of congenital heart disease summarizing its impact on the demographics of the congenital heart disease population and the progress made in order to improve outcomes in this patient population. Birth prevalence of congenital heart disease can be modified by many factors. As a result of decreasing mortality and increasing survival in all forms of congenital heart disease, the median age of patients has increased and adults now compose two-thirds of patients with congenital heart disease. Disease burden and resulting health services utilization increase significantly across the lifespan. Bridging the gap between policy and quality of care can be improved by referral to specialized adult congenital heart disease centers and planning delivery of specialized services that are commensurate with population needs, program accreditation criteria and certified training of designated workforce.

    Heart failure is a common late complication in adults with congenital heart defects, both repaired and unrepaired. The onset of clinical heart failure is associated with increased morbidity and mortality. Some patients with congenital heart disease may benefit from medications shown to improve survival in the population with acquired heart failure, but these same therapies may be of no benefit to other patients. Further studies are needed to better guide the choice of medical therapies.

    Congenital heart defects are the most common birth defects. Major advances in open-heart surgery have led to rapidly evolving cohorts of adult survivors and the majority of affected women now survive to childbearing age. The risk of cardiovascular complications during pregnancy and peripartum depends on the type of the underlying defect, the extent and severity of residual haemodynamic lesions and comorbidities. Careful individualized, multi-disciplinary pre-pregnancy risk assessment and counselling, including assessment of risks in the offspring and estimation on long-term outcomes of the underlying heart defect, will enable informed decision making. Depending on the estimated risks, a careful follow-up plan during pregnancy as well as a detailed plan for delivery and postpartum care can reduce the risks and should be made by the multi-disciplinary team.

    Congenital heart block (CHB) is rare disorder that has a higher mortality when associated with structural congenital heart defects. Very few cases have been reported in Sub-Saharan Africa (SSA). We present a case of complete CHB associated with a complex congenital heart defect in a neonate in Cameroon. A 1-month-old neonate in Cameroon was referred for the evaluation of bradycardia. The obstetrical ultrasound done during pregnancy revealed fetal bradycardia without further evaluation. Clinical examination showed well a developed neonate with bradycardia at 62 beats/minute, and mild cyanosis with oxygen saturation at 93% at room air. There were no signs of heart failure. Twelve lead electrocardiogram (ECG) demonstrated a complete atrioventricular conduction block with a junctional escape rhythm at 59/minute, left axis deviation and bi-ventricular hypertrophy. Two-dimensional echocardiography revealed a complex congenital heart disease with the following abnormalities: dextrocardia, complete atrioventricular canal with a single atrium and mild atrioventricular valve regurgitation and malposition of the great vessels with a posterior aorta and an anterior pulmonary artery. This case report highlights the challenges in the diagnosis and management of complex CHBs in low resource settings. A properly performed pregnancy follow-up with serial echocardiograms could aid in antenatal diagnosis and plan perinatal management when appropriate in order to optimize outcome. This emphasizes the clinical value of high quality antenatal care and proper screening. PMID:27904846

    Objective: To determine the delay in diagnosis of various types of congenital heart defects in children and factors associated with such delay. Patients and Methods: For this observational study, 354 patients having congenital heart disease (CHD) presenting for the first time to the Department of Cardiology, Children’s Hospital, Lahore, Pakistan, between January 1, 2015 and June 30, 2015, were enrolled after obtaining informed verbal consent from the guardian of each child. Demographical profile and various factors under observation were recorded. Results: Among the 354 enrolled children (M: F 1.7:1) with age ranging from 1 to 176 months (median 24 months), 301 (85.1%) had delayed diagnosis of CHD (mainly acyanotic 65.3%), with median delay (8 months). Main factors for delay were delayed first consultation to a doctor (37.2%) and delayed diagnosis by a health professional (22.5%). Other factors included delayed referral to a tertiary care hospital (13.3%), social taboos (13.0%), and financial constraints (12.3%). Most children were delivered outside hospital settings (88.7%). Children with siblings less than two (40%) were less delayed than those having two or more siblings (60%, P < 0.001). Conclusion: Diagnosis of congenital heart defect was delayed in majority of patients. Multiple factors such as lack of adequately trained health system and socioeconomic constraints were responsible for the delay. There is a need to develop an efficient referral system and improve public awareness in developing countries for early diagnosis and management of such children. PMID:27625517

    Pulmonary hypertension complicates the course of many children and adults with congenital heart diseases (CHDs). The increase in pulmonary pressure associated with CHD is secondary to either increased pulmonary blood flow or increased postcapillary pressures. Pulmonary arterial hypertension is in the vast majority associated with congenital cardiac shunts. Despite major advances in the understanding of the regulation of the pulmonary vascular bed and the pulmonary endothelial lesions leading to pulmonary vascular disease, despite the advances in surgical repair and the discovery of potential therapies in the pre- and postoperative period, pulmonary hypertension still carries a significant mortality and morbidity in patients with CHD. The recent introduction of targeted therapies in other forms of pulmonary arterial hypertension has led to a renewed interest in pulmonary hypertension associated with CHD and this particularly for the most advanced form, the so-called Eisenmenger syndrome (ES). This review summarizes the current knowledge on pulmonary hypertension associated with CHD, focusing on the pathophysiology and treatment of ES.

    Cases with congenital heart defects (CHD) often have other associated anomalies. The purpose of this investigation was to assess the prevalence and the types of associated anomalies in CHD in a defined population. The anomalies associated with CHD were collected in all live births, stillbirths and terminations of pregnancy during 26 years in 346,831 consecutive pregnancies of known outcome in the area covered by our population based registry of congenital anomalies. Of the 4005 cases with CHD born during this period (total prevalence of 115.5 per 10,000), 1055 (26.3%) had associated major anomalies. There were 354 (8.8%) cases with chromosomal abnormalities including 218 trisomies 21, and 99 (2.5%) nonchromosomal recognized dysmorphic conditions. There were no predominant recognized dysmorphic conditions, but VACTERL association. However, other recognized dysmorphic conditions were registered including Noonan syndrome, fetal alcohol syndrome, and skeletal dysplasias. Six hundred and two (15.0%) of the cases had non syndromic, non chromosomal multiple congenital anomalies (MCA). Anomalies in the urinary tract, the musculoskeletal, the digestive, and the central nervous systems were the most common other anomalies. Prenatal diagnosis was obtained in 18.7% of the pregnancies. In conclusion the overall prevalence of associated anomalies, which was one in four infants, emphasizes the need for a thorough investigation of cases with CHD. A routine screening for other anomalies may be considered in infants and in fetuses with CHD. One should be aware that the anomalies associated with CHD can be classified into a recognizable anomaly, syndrome or pattern in one out of nine cases with CHD.

  11. [Congenital heart defects in adulthood : Supraventricular tachycardia].

    PubMed

    Hebe, J

    2016-06-01

    Supraventricular tachycardia (SVT) based on congenital substrates, such as accessory pathways or dual atrioventricular nodal properties, occur with an increased probability linked to specific congenital heart defects (CHDs). In the literature, the association of Ebstein's anomaly with accessory pathways and with Mahaim fibers is most prominent. Compared with patients with otherwise normal hearts, the clinical relevance of SVT is typically more severe and therefore antiarrhythmia treatment is a necessity in many cases. Diagnostics, pharmaceutical treatment, and interventional therapy of SVT in patients with CHD are often demanding owing to anatomical, hemodynamic, and electro-anatomical peculiarities. The use of antiarrhythmic medication is often limited because of intolerable side effects and a lack of reliability in suppressing arrhythmia relapses in the long term. Within the last 15-20 years catheter ablation has thus become established as the first-choice treatment for SVT, even in patients with CHD. However, rates of success, recurrence, and risks are still inferior to those observed in patients with a normally functioning heart owing to the co-existence of vascular and cardiac anomalies, surgically created alterations, an unusual electro-anatomy, and lower tolerance to hemodynamic changes. Successful treatment in patients with CHDs and SVT requires a deep understanding and knowledge of all the disciplines discussed above and should only be practiced in dedicated centers, as patient numbers are small and therefore experience is limited.

  12. Evaluation of Adults With Congenital Heart Disease.

    2016-03-01

    The clinical approach to adults with congenital heart diseases (ACHDs) is unique in cardiovascular medicine because these patients encompass a broad range of presentations. Each patient, despite having similar diagnosis, will be anatomically and physiologically unlike others within ACHD population, in relation to the type of repair, age at repair, associated defects, with specific long-term risk factors and complications. Furthermore, as many patients will not complain of symptoms, clinical evaluation and diagnostic testing must also be based on the underlying main diagnostic category, with complete standardized lesion-specific clinical protocols, investigating all known risk factors specific for each congenital heart disease and performed as part of screening for significant long-term complications. The first part of this review will focus on clinical history, physical examination, and the most important diagnostic testing in ACHD population. The second part of the article will focus on some clinical issues we have to face in our daily practice, such as heart failure, cyanosis, and pulmonary hypertension. Furthermore, as survival rates of ACHD population continue to improve and patients with this condition live longer, we will briefly report on a new clinical concern regarding the impact of acquired morbidities like coronary artery disease that appear to be of greater importance in defining outcome in older patients with ACHD.

    2015-12-01

    Feline congenital heart disease is less commonly encountered in veterinary medicine than acquired feline heart diseases such as cardiomyopathy. Understanding the wide spectrum of congenital cardiovascular disease demands a familiarity with a variety of lesions, occurring both in isolation and in combination, along with an appreciation of complex nomenclature and variable classification schemes. This review begins with an overview of congenital heart disease in the cat, including proposed etiologies and prevalence, examination approaches, and principles of therapy. Specific congenital defects are presented and organized by a sequential segmental classification with respect to their morphologic lesions. Highlights of diagnosis, treatment options, and prognosis are offered. It is hoped that this review will provide a framework for approaching congenital heart disease in the cat, and more broadly in other animal species based on the sequential segmental approach, which represents an adaptation of the common methodology used in children and adults with congenital heart disease.

    Cardiac MRI (CMR) is replacing diagnostic cardiac catheterization as the modality of choice for anatomic and functional characterization of congenital heart disease (CHD) when echocardiographic imaging is insufficient. In this manuscript, we discuss the principles of anatomic imaging of CHD, placing emphasis on the appropriate choice and modification of pulse sequences necessary to evaluate infants and small children. Clinical examples are provided to illustrate the relative strengths and shortcomings of different CMR imaging techniques. Although cardiovascular function and flow techniques are not described, their role in evaluating the severity of anatomic defects is emphasized. Anatomic characterization represents the first component of a carefully-planned, integrated CMR assessment of CHD.

    Congenital heart defects affect nearly 1% of all newborns and are a significant cause of infant death. Clinical studies have identified a number of congenital heart syndromes associated with mutations in genes that are involved in the complex process of cardiogenesis. The African clawed frog, Xenopus, has been instrumental in studies of vertebrate heart development and provides a valuable tool to investigate the molecular mechanisms underlying human congenital heart diseases. In this review, we discuss the methodologies that make Xenopus an ideal model system to investigate heart development and disease. We also outline congenital heart conditions linked to cardiac genes that have been well-studied in Xenopus and describe some emerging technologies that will further aid in the study of these complex syndromes.

    PubMed

    Cho, Young Kuk; Ma, Jae Sook

    2013-03-01

    Despite developments in surgical techniques and other interventions, right ventricular (RV) failure remains an important clinical problem in several congenital heart diseases (CHD). RV function is one of the most important predictors of mortality and morbidity in patients with CHD. RV failure is a progressive disorder that begins with myocardial injury or stress, neurohormonal activation, cytokine activation, altered gene expression, and ventricular remodeling. Pressure-overload RV failure caused by RV outflow tract obstruction after total correction of tetralogy of Fallot, pulmonary stenosis, atrial switch operation for transposition of the great arteries, congenitally corrected transposition of the great arteries, and systemic RV failure after the Fontan operation. Volume-overload RV failure may be caused by atrial septal defect, pulmonary regurgitation, or tricuspid regurgitation. Although the measurement of RV function is difficult because of many reasons, the right ventricle can be evaluated using both imaging and functional modalities. In clinical practice, echocardiography is the primary mode for the evaluation of RV structure and function. Cardiac magnetic resonance imaging is increasingly used for evaluating RV structure and function. A comprehensive evaluation of RV function may lead to early and optimal management of RV failure in patients with CHD.

    2014-09-01

    The number of adults with congenital heart disease is increasing due to the great achievements in the field of paediatric cardiology, congenital heart surgery and intensive care medicine over the last decades. Mortality has shifted away from the infant and childhood period towards adulthood. As congenital heart disease patients get older, a high prevalence of cardiovascular risk factors is encountered similar to the general population. Consequently, the contribution of acquired morbidities, especially acquired heart conditions to patient outcome, is becoming increasingly important. Therefore, to continue the success story of the last decades in the treatment of congenital heart disease and to further improve the outcome of these patients, more attention has to be given to the prevention, detection and adequate therapy of acquired heart conditions. The aim of this review is to give an overview about acquired heart conditions that may be encountered in adults with congenital heart disease.

    Congenital heart disease in children is a type of birth defect. Previous studies have suggested that the transcription factor, TBX20, is involved in the occurrence and development of congenital heart disease in children; however, the specific regulatory mechanisms are yet to be evaluated. Hence, this study aimed to evaluate the relationship between the TBX20 polymorphism and the occurrence and development of congenital heart disease. The TBX20 gene sequence was obtained from the NCBI database and the polymorphic locus candidate was predicted. Thereafter, the specific gene primers were designed for the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) of DNA extracted from the blood of 80 patients with congenital heart disease and 80 controls. The results of the PCR were subjected to correlation analysis to identify the differences between the amplicons and to determine the relationship between the TBX20 gene polymorphism and congenital heart disease. One of the single nucleotide polymorphic locus was found to be rs3999950: c.774T>C (Ala265Ala). The TC genotype frequency in the patients was higher than that in the controls, similar to that for the C locus. The odds ratio of the TC genotypes was above 1, indicating that the presence of the TC genotype increases the incidence of congenital heart diseases. Thus, rs3999950 may be associated with congenital heart disease, and TBX20 may predispose children to the defect.

    BACKGROUND: Factors predictive of growth retardation and malnutrition in patients with congenital heart disease remain unclear. OBJECTIVES: This study aimed to measure antibody response to bovine casein through assessing serum casein antibody levels in malnourished patients three year or younger with CHD, and to determine its relationship to gastrointestinal symptoms, anthropometric measures, and laboratory data. SUBJECTS AND METHODS: This cross sectional case control study was conducted in sixty patients with CHD aged 4 to 72 months. They were subdivided into thirty patients with cyanotic and thirty patients with acyanotic CHD compared with thirty apparently healthy children. RESULTS: On comparison with controls, patients showed highly significant lower anthropometric measures, calcium, iron, hemoglobin levels, and higher serum levels of casein antibody, total iron binding capacity, and alkaline phoshatase activity (P<0.000). Serum levels of casein antibody showed significantly positive correlations with serum total iron binding capacity and alkaline phosphatase activities and negatively correlated with the age at onset of symptoms, anthropometric measures, serum calcium, and iron levels. CONCLUSION: Serum casein antibody levels play a significant role in the pathogenesis of malnutrition. Encouragement of breast feeding and avoidance of early cow’s milk consumption could prevent the development of antibody response to bovine casein. PMID:27275203

    OBJECTIVE: To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype. DATA SOURCES: Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on. DATA SYNTHESIS: Congenital heart disease is characterized by an etiologically heterogeneous and not well understood group of lesions. Several researchers have evaluated the presence of chromosomal abnormalities detected by the karyotype in patients with congenital heart disease. However, most of the articles were retrospective studies developed in Europe and only some of the studied patients had a karyotype exam. In this review, only one study was conducted in Latin America, in Brazil. It is known that chromosomal abnormalities are frequent, being present in about one in every ten patients with congenital heart disease. Among the karyotype alterations in these patients, the most important is the trisomy 21 (Down syndrome). These patients often have associated extra-cardiac malformations, with a higher risk of morbidity and mortality, which makes heart surgery even more risky. CONCLUSIONS: Despite all the progress made in recent decades in the field of cytogenetic, the karyotype remains an essential tool in order to evaluate patients with congenital heart disease. The detailed dysmorphological physical examination is of great importance to indicate the need of a karyotype. PMID:25119760

    Prevalence of congenital heart disease in the adult population has increased out of proportion to that of the pediatric population as survival has improved, and adult congenital heart disease patients make up a growing percentage of pediatric and adult cardiac intensive care unit admissions. These patients often develop complex multiorgan system disease as a result of long-standing altered cardiac physiology, and many require reoperation during adulthood. Practitioners who care for these patients in the cardiac intensive care unit must have a strong working knowledge of the pathophysiology of complex congenital heart disease, and a full team of specialists must be available to assist in the care of these patients. This chapter will review some of the common multiorgan system effects of long-standing congenital heart disease (eg, renal and hepatic dysfunction, coagulation abnormalities, arrhythmias) as well as some of the unique cardiopulmonary physiology of this patient population.

    This article presents the most relevant developments in 2013 in 3 key areas of cardiology: congenital heart disease, clinical cardiology, and heart failure and transplant. Within the area of congenital heart disease, we reviewed contributions related to sudden death in adult congenital heart disease, the importance of specific echocardiographic parameters in assessing the systemic right ventricle, problems in patients with repaired tetralogy of Fallot and indication for pulmonary valve replacement, and confirmation of the role of specific factors in the selection of candidates for Fontan surgery. The most recent publications in clinical cardiology include a study by a European working group on correct diagnostic work-up in cardiomyopathies, studies on the cost-effectiveness of percutaneous aortic valve implantation, a consensus document on the management of type B aortic dissection, and guidelines on aortic valve and ascending aortic disease. The most noteworthy developments in heart failure and transplantation include new American guidelines on heart failure, therapeutic advances in acute heart failure (serelaxin), the management of comorbidities such as iron deficiency, risk assessment using new biomarkers, and advances in ventricular assist devices.

    In the year 2012, 3 scientific sections-heart failure and transplant, congenital heart disease, and clinical cardiology-are presented together in the same article. The most relevant development in the area of heart failure and transplantation is the 2012 publication of the European guidelines for heart failure. These describe new possibilities for some drugs (eplerenone and ivabradine); expand the criteria for resynchronization, ventricular assist, and peritoneal dialysis; and cover possibilities of percutaneous repair of the mitral valve (MitraClip(®)). The survival of children with hypoplastic left heart syndrome in congenital heart diseases has improved significantly. Instructions for percutaneous techniques and devices have been revised and modified for the treatment of atrial septal defects, ostium secundum, and ventricular septal defects. Hybrid procedures for addressing structural congenital heart defects have become more widespread. In the area of clinical cardiology studies have demonstrated that percutaneous prosthesis implantation has lower mortality than surgical implantation. Use of the CHA2DS2-VASc criteria and of new anticoagulants (dabigatran, rivaroxaban and apixaban) is also recommended. In addition, the development of new sequencing techniques has enabled the analysis of multiple genes.

  7. Clues in diagnosing congenital heart disease.

    PubMed Central

    Moss, A. J.

    1992-01-01

    A number of practical office and bedside clues to cardiac disease in infants and children have been passed on through the years. They relate to the history, to the inspection and palpation components of the physical examination, and to knowledge of the specific cardiac defects that are likely to be associated with certain clinical syndromes. With the possible exception of coarctation of the aorta, the clues are not diagnostically specific. In many instances, however, they serve to narrow a broad array of diagnostic possibilities to 2 or 3 and, with the aid of other clues and auscultation, they can often be distinguished from one another. When a primary care physician is confronted with a child who has an incidental murmur that is "probably" innocent but could be organic, useful clues favoring an organic murmur are a history of congenital heart disease in a first-degree relative; a history of maternal rubella syndrome, alcohol use, or teratogenic drug use during pregnancy; a history of inappropriate sweating; a history of syncope, chest pain, or squatting; maternal diabetes mellitus; premature birth; birth at a high altitude; cyanosis; abnormal pulsations; recurrent bronchiolitis or pneumonia; chronic unexplained hoarseness; asymmetric facies with crying; and a physical appearance suggestive of a clinical syndrome.

    1999-01-01

    We performed renal function tests in 18 young patients, 1.8-14.6 years of age, with cyanotic congenital heart disease (CCHD). Glomerular filtration rate was normal (116 +/- 4.5 ml/min/1.73 m2), and renal plasma flow was decreased (410 +/- 25 ml/min/1.73 m2) with a rise in the filtration fraction (29 +/- 1.1%). The suggested pathophysiologic explanation of these findings is that the blood hyperviscosity seen in patients with CCHD causes an overall increase in renal vascular resistance with a rise in intraglomerular blood pressure. Despite a sluggish flow of blood in the glomerular capillary bed, the effective filtration pressure was adjusted to conserve the glomerular filtration rate. In addition to these renal hemodynamic parameters, we also studied renal acidification and tubular sodium and water handling during a forced water diuresis. Our data indicate that children with CCHD have a mild to moderate normal ion gap metabolic acidosis due to a low proximal tubular threshold for bicarbonate. Proximal tubular sodium and water reabsorption under these conditions were somewhat increased, though not significantly, probably due to intrarenal hydrostatic forces, in particular the rise in the oncotic pressure in the postglomerular capillaries in patients with high hematocrit values. The distal tubular functions such as sodium handling and acidification were not affected.

    Diastolic function is an important component of left ventricular (LV) function which is often overlooked. It can cause symptoms of heart failure in patients even in the presence of normal systolic function. The parameters used to assess diastolic function often measure flow and are affected by the loading conditions of the heart. The interpretation of diastolic function in the context of congenital heart disease requires some understanding of the effects of the lesions themselves on these parameters. Individual congenital lesions will be discussed in this paper. Recently, load-independent techniques have led to more accurate measurements of ventricular compliance and remodeling in heart disease. The combination of inflow velocities and tissue Doppler measurements can be used to estimate diastolic function and LV filling pressures. This review focuses on diastolic function and assessment in congenital heart disease. PMID:28261582

    PubMed

    2016-07-01

    Certain congenital heart anomalies make patients more susceptible to arrhythmia development throughout their lives. This poses the question whether prophylactic arrhythmia surgery should be incorporated into reparative open heart procedures for congenital heart disease. There is currently no consensus on what constitutes a standard prophylactic procedure, owing to the questions that remain regarding lesions to be performed; energy sources to use; proximity of energy source or incisions to coronary arteries, sinoatrial node, atrioventricular node; circumstances for right atrial, left atrial, or biatrial appendectomy; and whether to perform a right, left, or biatrial maze procedure. These considerations are important because prophylactic arrhythmia procedures are performed without knowing if the patient will actually develop an arrhythmia in his or her lifetime. By reviewing and summarizing the literature, congenital heart disease patients who are at risk for developing atrial arrhythmias can be identified and lesion sets can be suggested in an effort to standardize experimental protocols for prophylactic arrhythmia surgery.

    2016-06-01

    Cardiac resynchronization therapy (CRT) is an established treatment option for adult patients suffering heart failure due to idiopathic or ischemic cardiomyopathy associated with electromechanical dyssynchrony. There is limited evidence suggesting similar efficacy of CRT in patients with congenital heart disease (CHD). Due to the heterogeneity of structural and functional substrates, CRT implantation techniques are different with a thoracotomy or hybrid approach prevailing. Efficacy of CRT in CHD seems to depend on the anatomy of the systemic ventricle with best results achieved in systemic left ventricular patients upgraded to CRT from conventional pacing. Indications for CRT in patients with CHD were recently summarized in the Pediatric and Congenital Electrophysiology Society (PACES) and the Heart Rhythm Society (HRS) Expert Consensus Statement on the Recognition and Management of Arrhythmias in Adult Congenital Heart Disease and are presented in the text.

    Tobacco use and second-hand smoke exposure during pregnancy are linked to a host of deleterious effects on the pregnancy, fetus, and infant. Health outcomes improve when women quit smoking at any time during the pregnancy. However, the developing heart is vulnerable to noxious stimuli in the early weeks of fetal development, a time when many women are not aware of being pregnant. Congenital heart defects are the most common birth defects. Research shows an association between maternal tobacco exposure, both active and passive, and congenital heart defects. This article presents recent evidence supporting the association between intrauterine cigarette smoke exposure in the periconceptional period and congenital heart defects and discusses clinical implications for practice for perinatal and neonatal nurses.

    Congenital heart disease should be considered when evaluating calves with chronic respiratory signs, failure to thrive, poor growth, or if a murmur is heard on physical examination. Echocardiography is currently the gold standard for diagnosing congenital heart defects. A wide variety of defects, either alone or in combination with a ventricular septal defect, are possible. A standardized approach using sequential segmental analysis is required to fully appreciate the nature and severity of more complex malformations. The prognosis for survival varies from guarded to poor and depends on the hemodynamic relevance of the defects and the degree of cardiac compensation.

    Congenital cardiopathies are the most frequent congenital malformations. Reports of its prevalence around the world range from 2.1 to 12.3 for every 1000 newborns. Prevalence in our country remains unknown, but it probably occupies sixth place for mortality in infants less than a year old, and third place for mortality in those aged between 1 and 4 years. Based on birthrate, it is calculated that 10 to 12 000 infants in our country have some cardiac malformation. To understand the magnitude of the problem, it is important to identify the global number of newborns with some congenital cardiopathy each year and the type of malformation that they have, in order to determine the necessary resources and to plan their distribution. The main objective of regionalization is the justification of the resources with an emphasis in the specialized medical services to provide the best results for the patients. Hence, reason, based on the resources of each state, as well as their natality and infant mortality rates related to congenital cardiovascular pathology, we should proceed to regionalize the attention, and to simultaneously create a trustworthy database of the congenital cardiopathies. This should have many benefits, such as increase the number of total attended cases, improve the quality of attention, use appropriately the existent resources, and -surely- decrease the infant mortality.

    Objective: To evaluate the child development and evaluate a possible association with the commitment by biopsychosocial factors of children with and without congenital heart disease. Methods: Observational study of case-control with three groups: Group 1 - children with congenital heart disease without surgical correction; Group 2 - children with congenital heart disease who underwent surgery; and Group 3 - healthy children. Children were assessed by socio-demographic and clinical questionnaire and the Denver II Screening Test. Results: One hundred and twenty eight children were evaluated, 29 in Group 1, 43 in Group 2 and 56 in Group 3. Of the total, 51.56% are girls and ages ranged from two months to six years (median 24.5 months). Regarding the Denver II, the children with heart disease had more "suspicious" and "suspect/abnormal" ratings and in the group of healthy children 53.6% were considered with "normal" development (P≤0.0001). The biopsychosocial variables that were related to a possible developmental delay were gender (P=0.042), child's age (P=0.001) and income per capita (P=0.019). Conclusion: The results suggest that children with congenital heart disease are likely to have a developmental delay with significant difference between children who have undergone surgery and those awaiting surgery under clinical follow-up.

    Congenital heart disease is one of the major diagnoses in pediatric heart transplantation recipients of all age groups. Assessment of pulmonary vascular resistance in these patients prior to transplantation is crucial to determine their candidacy, however, it is frequently inaccurate because of their abnormal anatomy and physiology. This problem places them at significant risk for pulmonary hypertension and right ventricular failure post transplantation. The pathophysiology of pulmonary vascular disease in children with congenital heart disease depends on their pulmonary blood flow patterns, systemic ventricle function, as well as semilunar valves and atrioventricular valves structure and function. In our review we analyze the pathophysiology of pulmonary vascular disease in children with congenital heart disease and end-stage heart failure, and outline the state of the art pre-transplantation medical and surgical management to achieve reverse remodeling of the pulmonary vasculature by using pulmonary vasodilators and mechanical circulatory support.

    This article contains a review of some of the most important publications on congenital heart disease and pediatric cardiology that appeared in 2010 and up until September 2011. Of particular interest were studies on demographic changes reported in this patient population and on the need to manage the patients' transition from the pediatric to the adult cardiology department. This transition has given rise to the appearance of new areas of interest: for example, pregnancy in women with congenital heart disease, and the effect of genetic factors on the etiology and transmission of particular anomalies. In addition, this review considers some publications on fetal cardiology from the perspective of early diagnosis and, if possible, treatment. There follows a discussion on new contributions to Eisenmenger's syndrome and arrhythmias, as well as on imaging techniques, interventional catheterization and heart transplantation. Finally, there is an overview of the new version of clinical practice guidelines on the management of adult patients with congenital heart disease and of recently published guidelines on pregnancy in women with heart disease, both produced by the European Society of Cardiology.

    Pulmonary arterial hypertension is a common complication of congenital heart disease (CHD). Congenital cardiopathies are the most frequent congenital malformations. The prevalence in our country remains unknown, based on birthrate, it is calculated that 12,000 to 16,000 infants in our country have some cardiac malformation. In patients with an uncorrected left-to-right shunt, increased pulmonary pressure leads to vascular remodeling and endothelial dysfunction secondary to an imbalance in vasoactive mediators which promotes vasoconstriction, inflammation, thrombosis, cell proliferation, impaired apotosis and fibrosis. The progressive rise in pulmonary vascular resistance and increased pressures in the right heart provocated reversal of the shunt may arise with the development of Eisenmenger' syndrome the most advanced form de Pulmonary arterial hypertension associated with congenital heart disease. The prevalence of Pulmonary arterial hypertension associated with CHD has fallen in developed countries in recent years that is not yet achieved in developing countries therefore diagnosed late as lack of hospital infrastructure and human resources for the care of patients with CHD. With the development of targeted medical treatments for pulmonary arterial hypertension, the concept of a combined medical and interventional/surgical approach for patients with Pulmonary arterial hypertension associated with CHD is a reality. We need to know the pathophysiological factors involved as well as a careful evaluation to determine the best therapeutic strategy.

    Radionuclide angiocardiography provides a noninvasive assessment of cardiac function and blood flow through the heart and lungs. During the past three years, this procedure has been used at the Duke University Medical Center for evaluation of 343 patients with congenital heart disorders. A review of this experience shows tat the resulting data were frequently useful in the surgical management of these patients. In patients with abnormal blood flow patterns, noninvasive imaging of blood flow was useful before and after operative correction. Radionuclide measurements of left-to-right intracardiac shunts were sufficiently accurate for use in the initial evaluation of patients with murmurs and to document the absence of shunt after operative closure of intracardiac septal defects. Moreover, measurements of right-to-left cardiac shunts were of benefit in the management of children with cyanotic heart disease. Measurements of left ventricular function obtained during rest and exercise were most useful in patients with origin of the left coronary artery from the pulmonary artery and in patients with congenital valvular insufficiency. This experience demonstrates that radionuclide angiocardiography provides important measurements of central hemodynamics and cardiac function which are useful in the management of patients with congenital heart disorders.

    The impact of lifelong exposure to myocardial dysfunction in populations with congenital heart disease (CHD) is becoming increasingly recognized. Most children born with CHD now reach adulthood and the long-term sequelae of treatment are contributing to substantial comorbidity. The combination of structural changes present at birth with changes resulting from cardiac surgery can result in heart failure. This article reports on the current state of knowledge on the epidemiology of heart failure in this patient population.

    The study of congenital cardiopathies (CC) is one of the most clearly established indications of cardiac magnetic resonance imaging (CMRI). Different sequences, including anatomic, functional, flow (phase contrast), and 3D angiographic sequences, enable the diagnosis, treatment planning, and follow-up of these conditions. CMRI allows the anatomy, function, and alterations of flow in these cardiopathies to be evaluated in a single examination. Three-dimensional MR angiography enables the study of the great vessels and the anomalies associated to congenital heart defects in adults. This article describes an examination protocol and provides examples of MR images of the most common CC in adults: atrial septal defect, interventricular communication, atrioventricular canal, tetralogy of Fallot, transposition of the great arteries, congenitally corrected transposition of the great arteries, bicuspid aortic valve, subaortic stenosis, aortic coarctation, and Ebstein's anomaly.

    Adults living with congenital heart disease (CHD) now outnumber children with the disease. Thanks to medical advances over the past 75 years, many of these fatal childhood heart problems have changed to chronic medical conditions. As the population of adults with CHD increases, they will require increasingly complex medical, surgical and catheter-based therapies. In addition, social burdens including education, employment and insurability, which increase the societal costs of adult CHD, are now being recognized for adults living with CHD. This review summarizes the available literature on the economics of adult CHD.

    Objective: To study the pathogen distribution, antimicrobial susceptibility and risk factors of postoperative nosocomial infections among children with congenital heart disease. Methods: Three hundreds children with congenital heart disease admitted to our hospital to receive surgeries from February 2010 to February 2013 were selected. Results: A total of 120 children were tested as positive by sputum culture, with the infection rate of 40.0%. The top five most common pathogenic microorganisms included Staphylococcus epidermidis, Staphylococcus aureus, Enterococcus, Pseudomonas aeruginosa, and Candida albicans. S. epidermidis, S. aureus and Enterococcus were highly resistant to penicillin, azithromycin and erythromycin, moderately susceptible to levofloxacin and cefazolin, and completely susceptible to vancomycin. Multivariate Logistic regression analysis showed that hospitalization stay length, combined use of antibiotics, systemic use of hormones, mechanical ventilation and catheter indwelling were the independent risk factors of postoperative nosocomial infections (P<0.05). Conclusion: Nosocomial infection, which was the most frequent postoperative complication of pediatric congenital heart disease, was predominantly induced by Gram-positive bacteria that were highly susceptible to cephalosporins and vancomycin. Particular attention should be paid to decrease relevant risk factors to improve the prognosis. PMID:24948978

    Dyslipidemia is one of the main risk factors associated with cardiovascular diseases. Few data on the impacts of congenital heart diseases are available with regard to the prevalence of dyslipidemia in children. Our study evaluated the lipid profile in children with congenital heart disease at a referral center. From January 2011 to July 2012, 52 pediatric patients had their lipid, metabolic and clinical profiles traced. The mean age was 10.4 ± 2.8 years and male/female rate of 1.38:1. Our population had 53.8% patients with high levels of total cholesterol and 13.4% (CI 95 %, from 6.6 to 25.2%) of them also presenting LDL levels ≥ 130 mg/dL, which characterizes dyslipidemia. The group of dyslipidemic patients presented only two obese individuals. Our data show that the presence of congenital heart disease does not lead to higher risk associated with the prevalence of dyslipidemia. Therefore, the screening of this specific population should follow the regular pediatric guidelines, which are also independent of the nutritional status of the children tested. PMID:24061754

    Congenital heart disease (CHD) patients have an increased prevalence of extracardiac congenital anomalies (CAs) and risk of neurodevelopmental disabilities (NDDs). Exome sequencing of 1213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in the developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD, and CA but only 2% of patients with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, a regulator of mRNA splicing. Genes mutated in other cohorts examined for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients.

    The incidence of patients with degenerative valvular but also of patients with congenital heart disease surviving until adulthood or even old age will increase in the next decades. Auscultation with the stethoscope remains an important diagnostic means in the detection and treatment of heart disease. Heart murmurs (especially systolic heart murmurs) are extremely common. There are helpful clues to differentiate heart murmurs. It can occasionally be relatively simple to differentiate a systolic murmur due to valvular heart disease from an innocent, ejection murmur; however, there are important limitations of auscultation. Overall, auscultation and clinical examination alone do not suffice to correctly diagnose and treat patients with heart failure or a murmur Clinically significant aortic stenosis, aortic regurgitation and mitral regurgitation as well as hypertrophic cardiomyopathy are not uncommonly missed or misinterpreted. An echocardiographic exam is mandatory in all patients with more than a soft systolic murmur, any diastolic murmur, cardiac symptoms and/or ECG changes.

    Background Adult congenital heart disease (ACHD) clinicians are hampered by the paucity of data to inform clinical decision-making. The objective of this study was to identify priorities for clinical research in ACHD. Methods A list of 45 research questions was developed by the Alliance for Adult Research in Congenital Cardiology (AARCC), compiled into a survey, and administered to ACHD providers. Patient input was sought via the Adult Congenital Heart Association at community meetings and online forums. The 25 top questions were sent to ACHD providers worldwide via an online survey. Each question was ranked based on perceived priority and weighted based on time spent in ACHD care. The top 10 topics identified are presented and discussed. Results The final online survey yielded 139 responses. Top priority questions related to tetralogy of Fallot (timing of pulmonary valve replacement and criteria for primary prevention ICDs), patients with systemic right ventricles (determining the optimal echocardiographic techniques for measuring right ventricular function, and indications for tricuspid valve replacement and primary prevention ICDs), and single ventricle/Fontan patients (role of pulmonary vasodilators, optimal anticoagulation, medical therapy for preservation of ventricular function, treatment for protein losing enteropathy). In addition, establishing criteria to refer ACHD patients for cardiac transplantation was deemed a priority. Conclusions The ACHD field is in need of prospective research to address fundamental clinical questions. It is hoped that this methodical consultation process will inform researchers and funding organizations about clinical research topics deemed to be of high priority. PMID:24411207

    Background: There is a known association between congenital heart disease (CHD) and other congenital anomalies (CA). These associations have been altered by changes in prenatal factors in recent time. We reviewed the largest database of inpatient hospitalization information and analyzed the current association between common CHD diagnoses and other congenital anomalies. Materials and Methods: Case-control study design. We reviewed the Nationwide Inpatient Sample (NIS) database from 1998 to 2008 and identified all live births with CHD diagnosis (case) and live births without CHD diagnosis (control). We compared prevalence of associated congenital anomalies between the case and control groups. Results: Our cohort consisted of 97,154 and 12,078,482 subjects in the case and control groups, respectively. In the CHD population, prevalence of non-syndromic congenital anomaly (NSCA), genetic syndrome (GS), and overall extra-cardiac congenital anomaly (CA) were 11.4, 2.2, and 13.6%, respectively. In the control group, prevalence of NSCA, GS, and CA were 6.7, 0.3, and 7.0%, respectively. NSCA (odds ratio (OR): 1.88, confidence interval (CI): 1.73-1.94), GS (OR 2.52, CI 2.44-2.61), and overall CA (OR: 2.01, CI: 1.97-2.14) were strongly associated with CHD. Prevalence of GS and multiple organ-system CA decreased significantly over the study period. Conclusions: This is the largest and most comprehensive population-based study evaluating association between CHD and extra-cardiac malformation (ECM) in newborns. There was significant decrease in prevalence of GS and multiple CA over the study period. PMID:24987252

    Background Chronic heart failure is an important cause for morbidity and mortality in adults with congenital heart disease (ACHD). While NT-proBNP is an established biomarker for heart failure of non-congenital origin, its application in ACHD has limitations. The angiogenic factors Angiopoietin-1 and -2 (Ang-1, Ang-2), vascular endothelial growth factor (VEGF), and soluble receptor tyrosine kinase of the Tie family (sTie2) correlate with disease severity in heart failure of non-congenital origin. Their role in ACHD has not been studied. Methods In 91 patients Ang-2 and NT-proBNP were measured and related to New York Heart Association class, systemic ventricular function and parameters of cardiopulmonary exercise testing. Ang-1, VEGF, and sTie2 were also measured. Results Ang-2 correlates with NYHA class and ventricular dysfunction comparable to NT-proBNP. Further, Ang-2 showed a good correlation with parameters of cardiopulmonary exercise testing. Both, Ang-2 and NT-proBNP identified patients with severely limited cardiopulmonary exercise capacity. Additionally, Ang-2 is elevated in patients with a single ventricle physiology in contrast to NT-proBNP. VEGF, Ang-1, and sTie2 were not correlated with any clinical parameter. Conclusion The performance of Ang-2 as a biomarker for heart failure in ACHD is comparable to NT-proBNP. Its significant elevation in patients with single ventricle physiology indicates potential in this patient group and warrants further studies. PMID:23826161

    Congenital heart defects are the most prevalent type of birth defects. The association of air pollution with congenital heart defects is not well understood. We investigated a cohort of 8969 singleton live births in Lanzhou, China during 2010-2012. Using inverse distance weighting, maternal exposures to particulate matter with diameters ≤10 μm (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were estimated as a combination of monitoring station levels for time spent at home and in a work location. We used logistic regression to estimate the associations, adjusting for maternal age, education, income, BMI, disease, folic acid intake and therapeutic drug use, and smoking; season of conception, fuel used for cooking and temperature. We found significant positive associations of Patent Ductus Arteriosus (PDA) with PM10 during the 1st trimester, 2nd trimester and the entire pregnancy (OR 1st trimester = 3.96, 95% confidence interval (CI): 1.36, 11.53; OR 2nd trimester = 3.59, 95% CI: 1.57, 8.22; OR entire pregnancy = 2.09, 95% CI: 1.21, 3.62, per interquartile range (IQR) increment for PM10 (IQR = 71.2, 61.6, and 27.4 μg m-3, respectively)), and associations with NO2 during 2nd trimester and the entire pregnancy (OR 2nd trimester = 1.92, 95% CI: 1.11, 3.34; OR entire pregnancy = 2.32, 95% Cl: 1.14, 4.71, per IQR increment for NO2 (IQR = 13.4 and 10.9 μg m-3, respectively)). The associations for congenital malformations of the great arteries and pooled cases showed consistent patterns. We also found positive associations for congenital malformations of cardiac septa with PM10 exposures in the 2nd trimester and the entire pregnancy, and SO2 exposures in the entire pregnancy. Results indicate a health burden from maternal exposures to air pollution, with increased risk of congenital heart defects.

    In the context of congenital heart disease (CHD), the complex biochemical and physiologic response to the pressure- or volume-loaded ventricle can be induced by stenotic and shunt/regurgitant lesions, respectively. A range of transcatheter therapies have recently emerged to expand the therapeutic potential of the more traditional surgical and medical interventions for heart failure in patients with CHD. Together, these complementary interventions aim to treat the growing patient population with adult CHD (ACHD). In this article, the most commonly used transcatheter interventions for heart failure in patients with ACHD are reviewed.

    Patients with critical congenital heart disease are exposed to significant lifetime morbidity and mortality. Prenatal diagnosis can provide opportunities for anticipatory co-management of patients between palliative subspecialists and the cardiac care team. The benefits of palliative care include support for longitudinal decision-making and avoidance of interventions not consistent with family goals. Effectively counseling families requires an up-to-date understanding of outcomes and knowledge of provider biases. Patient-proxy reported quality of life (QOL) is highly variable in this population and healthcare providers need to be aware of limitations in their own subjective assessment of QOL.

    The association between infants with congenital heart block (CHB) and the presence or later development of maternal systemic lupus erythematosus or other connective-tissue disease (CTD) was reviewed in 67 cases. In 24 cases CHB was diagnosed at or before birth. Of nine necropsies on affected infants, seven showed endomyocardial fibrosis. The results suggest that one in three mothers who deliver babies with CHB have or will develop CTD. The association is probably explained by placental transfer of a maternal antibody. Awareness of the association may lead to prevention of the birth of children with CHB and better neonatal care of affected children. PMID:455010

    Advances in fetal echocardiography have improved prenatal diagnosis of congenital heart disease (CHD) and allowed better delivery and perinatal management. Some newborns with CHD require urgent intervention after delivery. In these cases, delivery close to a pediatric cardiac center may be considered, and the presence of a specialized cardiac team in the delivery room or urgent transport of the infant should be planned in advance. Delivery planning, monitoring in labor, rapid intervention at birth if needed, and avoidance of iatrogenic preterm delivery have the potential to improve outcomes for infants with prenatally diagnosed CHD.

    2017-03-01

    Radiofrequency catheter ablation (RFCA) is an important treatment modality to prevent ventricular tachycardia (VT) recurrence in patients with repaired congenital heart disease. Identification and ablation of anatomic isthmuses has improved acute ablation outcome with excellent VT-free survival in those with preserved biventricular function. Reports on RFCA for VT in patients with infiltrative disease are sparse and cardiac sarcoidosis seems to be the most prevalent cause for ventricular arrhythmia. Patients with active and ongoing inflammation are at high risk for VT recurrence. RFCA reduces the number of VT but often multiple procedures are required and long-term VT-free survival is unfavorable in those with left ventricular dysfunction.

    The National Heart, Lung, and Blood Institute convened a working group in January 2015 to explore issues related to an integrated data network for congenital heart disease research. The overall goal was to develop a common vision for how the rapidly increasing volumes of data captured across numerous sources can be managed, integrated, and analyzed to improve care and outcomes. This report summarizes the current landscape of congenital heart disease data, data integration methodologies used across other fields, key considerations for data integration models in congenital heart disease, and the short- and long-term vision and recommendations made by the working group.

    Congenital heart defects (CHD) affect approximately 7% of infants, and account for 3% of all infant deaths. CHD is most often caused by the defects associated with ductus arteriosus, which is a vessel that usually closes shortly after birth. The types of CHD include tetralogy of fallot, hypoplastic left heart syndrome, pulmonary atresia, total anomalous pulmonary venous return, transposition of great arteries, tricuspid atresia and truncus arteriosus. There are some risk factors that can increase the chance of a fetus developing CHD such as prematurity, an existing CHD in a first-degree relative, genetic syndromes, infections in utero, maternal drug consumptions and disorders. CHD is diagnosed is through different techniques including pulse oximetry, echocardiograms and physical exams. In this review, we examined the current incidence of CHD, the risk factors associated with CHD, the current methods of diagnosis and surgical options used to repair the defects. PMID:27168772

    With advances that have been made over the recent decades in transcatheter and surgical interventions, most patients with congenital heart disease (CHD) can survive into adulthood. Overall, probably half of these surviving patients are female. When these female CHD patients reach childbearing age, however, pregnancy management will be a major issue. In order to meet the demands of fetal growth, the maternal cardiovascular system starts a series of adaptations beginning in early pregnancy. These adaptations include: decreased systemic and pulmonary vascular resistances, decreased blood pressure, expansion of the blood volume, increased heart rate and increased cardiac output. For women with CHD, this hemodynamic alteration may increase the risks of adverse cardiovascular events as well as the fetal and neonatal complications. Therefore, proper risk stratification and effective counseling for women with CHD who are planning their pregnancies is an important undertaking. PMID:27122914

    Pediatric cardiac care in India is still in its infancy. We have no data on congenital heart disease (CHD) prevalence at birth or on proportional mortality from CHD. The resources are not only limited but also are at times improperly utilized. There are very few specialized pediatric cardiology training programs, those that are, are concentrated in certain regions of India and are often imparted through combined adult and pediatric programs. The existing number of trained personnel for pediatric cardiology and pediatric cardiac surgery is inadequate. Above all there is no national policy for pediatric heart care. Increasing awareness of the problem amongst the pediatricians through CMEs, seminars, symposia is likely to be most helpful in early diagnosis and timely referral of cases. Training programs exclusively dedicated to pediatric cardiology and pediatric cardiac surgery need to be established in centres with good standards of pediatric cardiac care.

    2001-06-01

    An analysis was done of available data from the Department of Statistics Malaysia, on the type of congenital abnormality contributing to death, to determine whether progress in health care over recent years was associated with any decline in mortality from congenital abnormality. A significant decline in death due to congenital abnormality was observed between 1991 and 1996. This was attributable to a decline in deaths due to congenital heart disease occurring because of improvements in cardiac surgical services for infants. In 1997 death due to congenital heart disease increased significantly. This could be attributed to improvements in the diagnosis of congenital heart disease in the neonate.

    Oculodentodigital dysplasia is caused by mutations in the GJA1 gene. Oculodentodigital dysplasia presents with a spectrum of clinical features including craniofacial, ocular, dental, and limb anomalies. Although recent findings implicate the major role of GJA1 during cardiac organogenesis, congenital heart defects are infrequently reported in oculodentodigital dysplasia. Here we report on two patients with GJA1 mutations presenting with cardiac malformations and type III syndactyly. Patient 1 presented with pulmonary atresia, an intact septum, right ventricular hypoplasia and tricuspid stenosis. The infant had a small nose, thin columella and bilateral 4-5 syndactyly of the fingers. A de novo c.226C>T (p.Arg76Cys) mutation was identified. Patient 2 presented at 6 months with a ventricular septal defect. The child had hypoplastic alae nasi with a thin columella and bilateral 4-5 syndactyly of the digits. A de novo missense mutation, c.145C>G (p.Gln49Glu) was found. Our two patients underscore the importance of cardiac evaluations as part of the initial workup for patients with findings of oculodentodigital dysplasia. Conversely, those patients with type III syndactyly and congenital heart defect should be screened for GJA1 mutations.

    2016-01-01

    For many years, the treatment of congenital heart diseases has been a field in which, based on the seriousness of these conditions, treatment options were viewed with the greatest deference. This has conditioned, in many cases, the interventions to be undertaken in each. In this sense, exercise was thought to have a negative impact and thus the practise of almost any physical activity was limited. Although there has recently been a change in the paradigm with respect to exercise, this idea continues to hold sway. For many cardiopathies, the information obtained through a stress test is essential in order to implement and supervise an exercise program. The aim of this study is to analyze the parameters within the stress test which allow for an adequate stratification of the risk to subjects with congenital heart diseases who undertake exercise, as well as their values in accordance with the type of pathology, the gravity of such, and the age of the patients. Furthermore, these parameters will be analyzed for both their survival markers and the protocols that can best be adjusted for patients with these characteristic.

    Purpose of review Recent methodological advances in computational simulations are enabling increasingly realistic simulations of hemodynamics and physiology, driving increased clinical utility. We review recent developments in the use of computational simulations in pediatric and congenital heart disease, describe the clinical impact in modeling in single ventricle patients, and provide an overview of emerging areas. Recent Findings Multiscale modeling combining patient specific hemodynamics with reduced order (i.e. mathematically and computationally simplified) circulatory models has become the defacto standard for modeling local hemodynamics and “global” circulatory physiology. We review recent advances that have enabled faster solutions, discuss new methods, (e.g. fluid structure interaction and uncertainty quantification), which lend realism both computationally and clinically to results, highlight novel computationally-derived surgical methods for single ventricle patients, and discuss areas in which modeling has begun to exert its influence including Kawasaki disease, fetal circulation, tetralogy of Fallot, (and pulmonary tree), and circulatory support. Summary Computational modeling is emerging as a crucial tool for clinical decision-making and evaluation of novel surgical methods and interventions in pediatric cardiology and beyond. Continued development of modeling methods, with an eye towards clinical needs, will enable clinical adoption in a wide range of pediatric and congenital heart diseases. PMID:26262579

    2014-01-01

    Major advances in noninvasive imaging of adult congenital heart disease have been accomplished. These tools play now a key role in comprehensive diagnostic work-up, decision for intervention, evaluation for the suitability of specific therapeutic options, monitoring of interventions and regular follow-up. Besides echocardiography, magnetic resonance (CMR) and computed tomography (CT) have gained particular importance. The choice of imaging modality has thus become a critical issue. This review summarizes strengths and limitations of the different imaging modalities and how they may be used in a complementary fashion. Echocardiography obviously remains the workhorse of imaging routinely used in all patients. However, in complex disease and after surgery echocardiography alone frequently remains insufficient. CMR is particularly useful in this setting and allows reproducible and accurate quantification of ventricular function and comprehensive assessment of cardiac anatomy, aorta, pulmonary arteries and venous return including complex flow measurements. CT is preferred when CMR is contraindicated, when superior spatial resolution is required or when "metallic" artefacts limit CMR imaging. In conclusion, the use of currently available imaging modalities in adult congenital heart disease needs to be complementary. Echocardiography remains the basis tool, CMR and CT should be added considering specific open questions and the ability to answer them, availability and economic issues.

    Exercise capacity in adults with various forms of congenital heart disease is substantially lower than that of the general population. Although the underlying congenital heart defect, and its sequelae, certainly contribute to observed exercise limitations, there is evidence suggesting that deconditioning and a sedentary lifestyle are important implicated factors. The prevalence of acquired cardiovascular comorbidities is on the increase in the aging population with congenital heart disease, such that obesity and a sedentary lifestyle confer increased risk. Health fears and misconceptions are common barriers to regular physical activity in adults with congenital heart disease, despite evidence linking lower functional capacity to poor outcomes, and data supporting the safety and efficacy of exercise in bestowing numerous physical and psychosocial rewards. With few exceptions, adults with congenital heart disease should be counselled to exercise regularly. In this contemporary review, we provide a practical approach to assessing adults with congenital heart disease before exercise training. We examine available evidence supporting the safety and benefits of exercise training. Risks associated with exercise training in adults with congenital heart disease are discussed, particularly with regard to sudden cardiac death. Finally, recommendations for exercise training are provided, with consideration for the type of congenital heart disease, the nature (ie, static vs dynamic) and intensity (ie, low, medium, high) of the physical activity, and associated factors such as systemic ventricular dysfunction and residual defects. Further research is required to determine optimal exercise regimens and to identify effective strategies to implement exercise training as a key determinant of healthy living.

    Mouse model is ideal for investigating the genetic and developmental etiology of congenital heart disease. However, cardiovascular phenotyping for the precise diagnosis of structural heart defects in mice remain challenging. With rapid advances in imaging techniques, there are now high throughput phenotyping tools available for the diagnosis of structural heart defects. In this review, we discuss the efficacy of four different imaging modalities for congenital heart disease diagnosis in fetal/neonatal mice, including noninvasive fetal echocardiography, micro-computed tomography (micro-CT), micro-magnetic resonance imaging (micro-MRI), and episcopic fluorescence image capture (EFIC) histopathology. The experience we have gained in the use of these imaging modalities in a large-scale mouse mutagenesis screen have validated their efficacy for congenital heart defect diagnosis in the tiny hearts of fetal and newborn mice. These cutting edge phenotyping tools will be invaluable for furthering our understanding of the developmental etiology of congenital heart disease.

    From the stand point of radiographic analysis most of the complex cyanotic congenital heart diseases (CHD), can be divided into those associated with decreased or increased pulmonary vascularity. Combination of a specific cardiac configuration and status of lung vasculature in a clinical context allows plain film diagnosis to be predicted in some CHD. Correlation of the position of the cardiac apex in relation to the visceral situs is an important information that can be obtained from the plain film. This information helps in gathering information about the atrio-ventricular, ventricular arterial concordance or discordance. Categorization of the cyanotic heart disease based on vascularity is presented below. Thorough understanding of cardiac anatomy by different imaging methods is essential in understanding and interpreting complex cardiac disease. Basic anatomical details and background for interpretation are provided in the previous parts of this presentation. PMID:27630924

    The purpose of this article was to examine reproductive health issues for women with congenital structural abnormalities of the heart. Because of surgical advances and innovations in healthcare, infants with congenital heart disease often live now into adulthood. Women with congenital heart disease have reported the desire to have children but expressed concern about fertility and the health consequences of pregnancy. Although many women with congenital heart disease are able to give birth without adverse outcomes, life-threatening complications can occur. Best practices for the care of women with congenital heart disease are grounded in an understanding of how cardiac defects may affect pregnancy and in communicating the implications of cardiac defects for reproductive health to support informed decision making.

    Due to improving results in congenital heart surgery, the number of adult patients with congenital heart defect is increasing. The question is: what kind of problems can be managed in this patient-group? The authors review the different problems of management of congenital heart defects in adults based on national and international literature data. Simple defects recognised in adults, postoperative residual problems, changing of small grafts and valves, correction of primary or operated coarctation aortae can be usually managed without problems. A very close follow-up is necessary to establish the correct period for heart transplantation in patients with transposition of great arteries with Senning/Mustard operation, and univentricular heart corrected with "Fontan-circulation" type surgical procedure. The authors conclude that although the number of patients increases, only a few congenital heart diseases may cause problems. It seems important (1) to monitor asymptomatic patient who underwent operation (Fallot-IV, Ross procedure, etc.), (2) follow up regularly patients who underwent Senning/Mustard procedure (magnetic resonance imaging, echocardiography, brain natriuretic peptide measurement), (3) define the proper period of preparation for heart transplantation of patients with a univentricular heart, with special attention to the possibility of multiorgan (lung, liver, etc.) failure. Due to the improvement of foetal diagnosis of congenital heart defects, the number of patients with complex congenital heart defects is decreasing. The standard management of these patients could be primary heart transplantation in infancy.

    Background: Information about known risk factors for congenital heart disease is scarce. In this population-based study, we aimed to investigate the relation between maternal chronic disease and congenital heart disease in offspring. Methods: The study cohort consisted of 1 387 650 live births from 2004 to 2010. We identified chronic disease in mothers and mild and severe forms of congenital heart disease in their offspring from Taiwan’s National Health Insurance medical claims. We used multivariable logistic regression analysis to assess the associations of all cases and specific types of congenital heart disease with various maternal chronic diseases. Results: For mothers with the following chronic diseases, the overall prevalence of congenital heart disease in their children was significantly higher than for mothers without these diseases: diabetes mellitus type 1 (adjusted odds ratio [OR] 2.32, 95% confidence interval [CI] 1.66–3.25), diabetes mellitus type 2 (adjusted OR 2.85, 95% CI 2.60–3.12), hypertension (adjusted OR 1.87, 95% CI 1.69–2.07), congenital heart defects (adjusted OR 3.05, 95% CI 2.45–3.80), anemia (adjusted OR 1.31, 95% CI 1.25–1.38), connective tissue disorders (adjusted OR 1.39, 95% CI 1.19–1.62), epilepsy (adjusted OR 1.37, 95% CI 1.08–1.74) and mood disorders (adjusted OR 1.25, 95% CI 1.11–1.41). The same pattern held for mild forms of congenital heart disease. A higher prevalence of severe congenital heart disease was seen only among offspring of mothers with congenital heart defects or type 2 diabetes. Interpretation: The children of women with several kinds of chronic disease appear to be at risk for congenital heart disease. Preconception counselling and optimum treatment of pregnant women with chronic disease would seem prudent. PMID:27729382

    Introduction: Congenital heart defects are the most common congenital anomalies and occur with an incidence from 0.8 to 1% per 1000 live births. In recent years, the pulse oximetry has become a strong candidate for detecting cyanogen congenital heart defects and in combination with routine clinical exam can improve diagnostic of congenital heart diseases. Objective: To apply the modern algorithm for early detection of congenital heart defects in order to improve the diagnosis in the neonatal period. Patients and Methods: This was a prospective study that included children born in Bihac Cantonal Hospital during 2012. The diagnostic algorithm included a clinical examination of the newborn, measuring of transcutaneous oxygen saturation with the pulse oximeter between 24 and 48 hours of life, and, in some cases, additional tests (cardiac ultrasound). Results: A total of 1,865 children were examined. The application of diagnostic protocol identified the existence of congenital heart defects in 29 children. In re-evaluating the auscultator and ultrasound findings, we identified congenital heart defects in 19 children. Conclusion: The application of the modern algorithm for early detection of congenital heart diseases in the neonatal period can significantly improve the making of diagnosis of these anomalies. The concept is simple, inexpensive and applicable in most maternity wards. PMID:27994302

    Most infants born with congenital heart disease (CHD) are now expected to reach adulthood. However, adults with CHD of moderate or great complexity remain at elevated risk of heart failure, arrhythmias, additional surgeries and interventional procedures, and premature mortality. This creates a need for lifelong specialized cardiac care and leads to 2 sets of potential challenges: (1) the transition from pediatric to adult care and (2) the psychosocial implications of coping with a chronic and often life-shortening medical condition. Many adolescents struggle with the transition to adult care, and mood and anxiety disorders are not uncommon in the adult setting.

    2013-01-01

    Drawing on attachment and caregiving theory and the concept of motivation, the purpose of this descriptive study was to examine parents’ retrospective accounts of their prenatal experiences after receiving the diagnosis of a fetal heart defect. These parents constituted a subgroup of participants in a larger longitudinal study of parenting an infant with a complex congenital heart defect. Data were derived from 14 semistructured interviews with 13 mothers and 3 fathers in the home or hospital setting. A directed content analysis yielded a central category of preparing heart and mind for infant caregiving. Preparing heart and mind is a preliminary caregiving goal within the caregiving system that generates intentions and expectations indicative of specific caregiving motivations to relate to the baby, handle circumstances practically, and manage infant medical care. A theoretical model illustrates the prenatal process these parents engaged in to provide care to their infants with life-threatening medical conditions. PMID:22927700

    The role of hemodynamics in early heart development is poorly understood. In order to successfully assess the impact of hemodynamics on development, we need to monitor and perturb blood flow, and quantify the resultant effects on morphology. Here, we have utilized cardiac optical pacing to create regurgitant flow in embryonic hearts and OCT to quantify regurgitation percentage and resultant morphology. Embryonic quail in a shell-less culture were optically paced at 3 Hz (well above the intrinsic rate or 1.33-1.67 Hz) on day 2 of development (3-4 weeks human) for 5 minutes. The pacing fatigued the heart and led to a prolonged period (> 1 hour) of increased regurgitant flow. Embryos were kept alive until day 3 (cardiac looping - 4-5 weeks human) or day 8 (4 chambered heart - 8 weeks human) to quantify resultant morphologic changes with OCT. All paced embryos imaged at day 3 displayed cardiac defects. The extent of regurgitant flow immediately after pacing was correlated with cardiac cushion size 24-hours post pacing (p-value < 0.01) with higher regurgitation leading to smaller cushions. Almost all embryos (16/18) surviving to day 8 exhibited congenital heart defects (CHDs) including 11/18 with valve defects, 5/18 with ventricular septal defects and 5/18 with hypoplastic right ventricles. Our data suggests that regurgitant flow leads to smaller cushions, which develop into abnormal valves and septa. Our model produces similar phenotypes as found in our fetal alcohol syndrome and velo-cardio-facial/DiGeorge syndrome models suggesting that hemodynamics plays a role in these syndromes as well. Utilizing OCT and optical pacing to understand hemodynamics in development is an important step towards determining CHD mechanisms and ultimately developing earlier treatments.

    Mammalian heart development is built on highly conserved molecular mechanisms with polygenetic perturbations resulting in a spectrum of congenital heart diseases (CHD). However, knowledge of cardiogenic ontogeny that regulates proper cardiogenesis remains largely based on candidate-gene approaches. Mapping the dynamic transcriptional landscape of cardiogenesis from a genomic perspective is essential to integrate the knowledge of heart development into translational applications that accelerate disease discovery efforts toward mechanistic-based treatment strategies. Herein, we designed a time-course transcriptome analysis to investigate the genome-wide dynamic expression landscape of innate murine cardiogenesis ranging from embryonic stem cells to adult cardiac structures. This comprehensive analysis generated temporal and spatial expression profiles, revealed stage-specific gene functions, and mapped the dynamic transcriptome of cardiogenesis to curated pathways. Reconciling known genetic underpinnings of CHD, we deconstructed a disease-centric dynamic interactome encoded within this cardiogenic atlas to identify stage-specific developmental disturbances clustered on regulation of epithelial-to-mesenchymal transition (EMT), BMP signaling, NF-AT signaling, TGFb-dependent EMT, and Notch signaling. Collectively, this cardiogenic transcriptional landscape defines the time-dependent expression of cardiac ontogeny and prioritizes regulatory networks at the interface between health and disease.

    Abstract. Coincidental cyanotic congenital heart disease and pheochromocytoma is uncommon, although some cases have been reported. We describe a girl aged 15 yr and 11 mo with pheochromocytoma and tricuspid atresia treated by performing the Fontan surgery. The patient did not have any specific symptoms of syndrome related to pheochromoytoma or a family history of pheochromocytoma. During cardiac catheterization, her blood pressure increased markedly, and an α-blocker was administered. Catecholamine hypersecretion was observed in the blood and urine, and abdominal computed tomography revealed a tumor in the right adrenal gland. Scintigraphy showed marked accumulation of 123I-metaiodobenzylguanidine in the tumor, which led to a diagnosis of pheochromocytoma. We did not detect any germline mutations in the RET, VHL, SDHB, SDHD, TMEM127, or MAX genes. This patient had experienced mild systemic hypoxia since birth, which may have contributed to the development of pheochromocytoma. PMID:27212797

    Congenital heart diseases (CHDs) are recognized as the most common type of birth malformations. Although recent advances in pre- and neonatal diagnosis as well as in surgical procedures have reduced the morbidity and mortality for many CHD, the etiology for CHD remains undefined. In non-syndromic and isolated (without a familial history or a Mendelian inheritance) forms of CHDs, a multifactorial pathogenesis with interplay between inherited and non-inherited causes is recognized. In this paper, we discuss the current knowledge of the potential molecular mechanisms, mediating abnormal cardiac development in non-syndromic and isolated CHD, including mutations in cardiac transcription factors, the role of somatic mutations and epigenetic alterations as well as the influence of gene-environment interactions. In the near future, the advent of high-throughput genomic technologies with the integration of system biology will expand our understanding of isolated, non-syndromic CHDs for their prevention, early diagnosis and therapy.

    Structural birth defects in the kidney and urinary tract are observed in 0.5% of live births and are a major cause of end-stage renal disease, but their genetic aetiology is not well understood. Here we analyse 135 lines of mice identified in large-scale mouse mutagenesis screen and show that 29% of mutations causing congenital heart disease (CHD) also cause renal anomalies. The renal anomalies included duplex and multiplex kidneys, renal agenesis, hydronephrosis and cystic kidney disease. To assess the clinical relevance of these findings, we examined patients with CHD and observed a 30% co-occurrence of renal anomalies of a similar spectrum. Together, these findings demonstrate a common shared genetic aetiology for CHD and renal anomalies, indicating that CHD patients are at increased risk for complications from renal anomalies. This collection of mutant mouse models provides a resource for further studies to elucidate the developmental link between renal anomalies and CHD.

    Pulmonary Hypertension (PH) is definited by a mean pulmonary artery pressure (PAPm) >25 mmHg at rest. The Dana Point 2008 Revised Classification System represents the most recent classification system update with respect of various etiologies of PH. About 10 % of adolescents or adults with uncorrected congenital heart disease (CHD) with left-to-right shunt and high pulmonary blood flow develop Pulmonary Arterial Hypertension (PAH) . Progressive vascular remodeling and increase in pulmonary vascular resistance (PVR) may ultimately lead to reversal of the shunt (pulmonary to systemic) causing cyanosis and determining the so-called Eisenmenger Syndrome (ES). Recent advances in the early diagnosis and medical targeted treatment of adult patients with CHD-PAH and ES can improve PAP, PVR and exercise tolerance, together with NYHA Class and survival, and may potentially reverse the vascular remodeling process in selected patients.

    Structural birth defects in the kidney and urinary tract are observed in 0.5% of live births and are a major cause of end-stage renal disease, but their genetic aetiology is not well understood. Here we analyse 135 lines of mice identified in large-scale mouse mutagenesis screen and show that 29% of mutations causing congenital heart disease (CHD) also cause renal anomalies. The renal anomalies included duplex and multiplex kidneys, renal agenesis, hydronephrosis and cystic kidney disease. To assess the clinical relevance of these findings, we examined patients with CHD and observed a 30% co-occurrence of renal anomalies of a similar spectrum.

    The successful pediatric management of congenital heart disease has resulted in increasing numbers of these patients in the reproductive age group and increasing clinical challenges for their physicians. These challenges can be met successfully, with improved results for mother and child, through a concerted comprehensive team approach that relies on a thorough understanding of the patient's underlying cardiac pathology and its anticipated interaction with the pregnancy, and ongoing close evaluation and communication with a team of trained and experienced specialist, including (but not limited to) cardiologist, obstetricians, anesthetists, pediatricians, clinical nurse specialists, and clinical geneticists. Such teams are not always available locally and it will be necessary to refer medium- and high-risk patients to a specialized tertiary care center.

    2014-04-01

    Congenital heart disease (CHD) affects nearly 1 % of the population. It is a complex disease, which may be caused by multiple genetic and environmental factors. Studies in human genetics have led to the identification of more than 50 human genes, involved in isolated CHD or genetic syndromes, where CHD is part of the phenotype. Furthermore, mapping of genomic copy number variants and exome sequencing of CHD patients have led to the identification of a large number of candidate disease genes. Experiments in animal models, particularly in mice, have been used to verify human disease genes and to gain further insight into the molecular pathology behind CHD. The picture emerging from these studies suggest that genetic lesions associated with CHD affect a broad range of cellular signaling components, from ligands and receptors, across down-stream effector molecules to transcription factors and co-factors, including chromatin modifiers.

    The purpose of this study was to describe pain in adults post surgical repair for congenital heart defects. What is the intensity, sensory, and affective dimensions of pain experienced post-operatively? What is the trend in pain experienced post-operatively over time? What is the effectiveness of post-operative pain management strategies? What factors influence the dimensions of post-operative pain experienced? A descriptive prospective repeated measures design was used with 30 adult congenital heart (ACH) post-operative patients. Pain assessments using the McGill Short Form Questionnaire (MSFQ), a visual analogue pain scale (VAP), and recordings of other variables (analgesic, anxiety, activity level, non-pharmacologic intervention) were performed three times daily until hospital discharge. Mean pain intensity scores ranged from 2.44 +/- 1.31 following extubation to 1.30 +/- 0.66 on post-operative day (POD) five (scale, 0-5). Mean MSFQ scores ranged from 9.26 +/- 7.21 following extubation to 4.40 +/- 5.22 on POD five (scale, 0-45). Mean VAP scores ranged from 50.77 +/- 25.79 following extubation to 18.76 +/- 18.50 on POD five (scale, 0-100). Mean number of narcotic doses per day ranged from 4.61 +/- 2.01 to 1.88 +/- 1.98 on PODs one and five, respectively. Anxiety predicted VAP and MSFQ scores on PODs one and two; anxiety and analgesia doses predicted VAP and MSFQ scores on POD three; analgesia doses predicted MSFQ scores, analgesia and anxiety predicted VAP scores on POD four; analgesia doses and anxiety predicted VAP and MSFQ scores on POD five. No relationships were found among pain and other demographic, treatment, or clinical variables. Overall, pain was reported as mild to moderate intensity, variable in sensations, decreased over time, and adequately managed.

  1. Forkhead box transcription factors in embryonic heart development and congenital heart disease.

    PubMed

    Zhu, Hong

    2016-01-01

    Embryonic heart development is a very complicated process regulated precisely by a network composed of many genes and signaling pathways in time and space. Forkhead box (Fox, FOX) proteins are a family of transcription factors characterized by the presence of an evolutionary conserved "forkhead"or "winged-helix" DNA-binding domain and able to organize temporal and spatial gene expression during development. They are involved in a wide variety of cellular processes, such as cell cycle progression, proliferation, differentiation, migration, metabolism and DNA damage response. An abundance of studies in model organisms and systems has established that Foxa2, Foxc1/c2, Foxh1 and Foxm1, Foxos and Foxps are important components of the signaling pathways that instruct cardiogenesis and embryonic heart development, playing paramount roles in heart development. The previous studies also have demonstrated that mutations in some of the forkhead box genes and the aberrant expression of forkhead box gene are heavily implicated in the congenital heart disease (CHD) of humans. This review primarily focuses on the current understanding of heart development regulated by forkhead box transcription factors and molecular genetic mechanisms by which forkhead box factors modulate heart development during embryogenesis and organogenesis. This review also summarizes human CHD related mutations in forkhead box genes as well as the abnormal expression of forkhead box gene, and discusses additional possible regulatory mechanisms of the forkhead box genes during embryonic heart development that warrant further investigation.

    A survey conducted by cardiologists in Soweto, Johannesburg, provided an opportunity of assessing the frequency of congenital heart disease in black schoolchildren. Among 12,050 schoolchildren aged 2 to 18 years, 48 had a congenital heart defect, yielding a prevalence of 3.9 per 1000. Only in 2- to 6-year-old children did the prevalence exceed that of rheumatic heart disease. The distribution of the types of defects was largely similar to that reported in other surveys with a predominance (52%) of ventricular septal defects. Two unusual findings were the unexplained absence of persistent ductus arteriosus in these children, and the detection of 5 children with situs inversus (1 in 2410). In all but one child, the congenital heart defect was first discovered during the survey. Despite the limitations of a prevalence study, it can be concluded that congenital heart disease is at least as common in this South African black community as in Caucasians. PMID:465225

    Heart failure (HF) is the leading cause of death in adults with repaired congenital heart disease (CHD). However there is currently little evidence to guide treatment strategies in this growing group of patients. Unlike the majority of HF, which is usually caused by LV systolic or diastolic dysfunction, CHD-HF is more often a consequence of RV disease, valve dysfunction, shunting or pulmonary hypertension. It is therefore not appropriate to extrapolate from the acquired HF literature and apply it to this heterogeneous population of CHD patients. Additionally, patients with CHD have been excluded from most large trials of medical or device therapy of HF, which has resulted in small retrospective and underpowered studies in the CHD population. This article critically reviews the current knowledge about CHD-HF, paying particular attention to medical therapy in different CHD populations, cardiac resynchronisation therapy and implantable cardiac defibrillators, and the challenges of heart transplantation and mechanical circulatory support in CHD patients.

    Africa has one of the highest prevalence of heart diseases in children and young adults, including congenital heart disease (CHD) and rheumatic heart disease (RHD). We present here an extensive review of recent data from the African continent highlighting key studies and information regarding progress in CHD and RHD since 2005. Main findings include evidence that the CHD burden is underestimated mainly due to the poor outcome of African children with CHD. The interest in primary prevention for RHD has been recently re-emphasised, and new data are available regarding echocardiographic screening for subclinical RHD and initiation of secondary prevention. There is an urgent need for comprehensive service frameworks to improve access and level of care and services for patients, educational programmes to reinforce the importance of prevention and early diagnosis and a relevant research agenda focusing on the African context.

    A 41-year-old male with heterotaxy (left isomerism) and dextrocardia composed by single ventricle, absent inferior vena cava, bilateral superior vena cava (SVC), common atrioventricular valve has received orthotopic heart transplantation (HTx) after long waiting period as Status-1. Reconstructions of bilateral SVC and hepatic vein route were successful without use of prosthetic material, and the donor heart was placed in the left mediastinum. In spite of satisfactory early recovery, the patient expired 4 months after transplantation mainly from fungal infection which developed following humoral rejection. HTx for adult patients with complex congenital heart disease is demanding in technical as well as pre- and post-transplant management, and indication should be critically determined.

    Headache in adult patients with congenital heart disease may be a manifestation of the underlying cardiac condition or more common alternative causes of headache. In patients with pre-existing congenital heart disease, consideration of potentially uncommon aetiologies of headache is important. We report an uncommon case of headache in a patient with complex congenital heart disease characterised by Ebstein's anomaly with previous surgical repair complicated by idiopathic intracranial hypertension. This case illustrates the importance of understanding the implications of headache with reference to the underlying cardiac disease as well as specific issues related to a relatively young cohort of patients.

    Background Administrative databases are often used for congenital heart disease research and evaluation, with little validation of the accuracy of the diagnostic codes. Methods Metropolitan Atlanta Congenital Defects Program surveillance records were reviewed and classified using a version of the International Pediatric and Congenital Cardiac Code. Using this clinical nomenclature as the referent, we report the sensitivity and false positive fraction (1 – positive predictive value) of the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for tetralogy of Fallot, transposition of the great arteries, and hypoplastic left heart syndrome. Results We identified 4918 infants and foetuses with congenital heart disease from the surveillance records. Using only the International Classification of Diseases diagnosis codes, there were 280 records with tetralogy, 317 records with transposition, and 192 records with hypoplastic left heart syndrome. Based on the International Pediatric and Congenital Cardiac Code, 330 records were classified as tetralogy, 163 records as transposition, and 179 records as hypoplastic left heart syndrome. The sensitivity of International Classification of Diseases diagnosis codes was 83% for tetralogy, 100% for transposition, and 95% for hypoplastic left heart syndrome. The false positive fraction was 2% for tetralogy, 49% for transposition, and 11% for hypoplastic left heart syndrome. Conclusions Analyses based on International Classification of Diseases diagnosis codes may have substantial misclassification of congenital heart disease. Isolating the major defect is difficult, and certain codes do not differentiate between variants that are clinically and developmentally different. PMID:19063779

    Genetic variation in specific transcription factors during heart formation may lead to congenital heart disease (CHD) or even miscarriage. The aim of the present study was to identify CHD‑associated genes using next generation sequencing (NGS). The whole exome DNA sequence was obtained from a stillborn fetus diagnosed with tricuspid atresia and complete transposition of the great arteries using high‑throughput sequencing methods. Subsequently, genetic variants of CHD‑associated genes were selected and verified in 215 non‑syndromic CHD patients and 249 healthy control subjects using polymerase chain reaction combined with Sanger sequencing. Genetic variants of previously reported CHD‑inducing genes, such as cysteine rich with EGF like domains 1 and cbp/p300‑interacting transactivator with Glu/Asp rich carboxy‑terminal domain 2, were discovered through the NGS analysis. In addition, a novel non‑synonymous mutation of the iroquois homeobox 1 (IRX1) gene (p.Gln240Glu) was identified. A total of three non‑synonymous mutations (p.Gln240Glu, p.Ser298Asn and p.Ala381Glu) of the IRX1 gene were verified in 215 non‑syndromic CHD patients, but not in 249 healthy volunteers. The results demonstrated that NGS is a powerful tool to study the etiology of CHD. In addition, the results suggest that genetic variants of the IRX1 gene may contribute to the pathogenesis of CHD.

    There have been significant advancements in the ability of echocardiography to provide both morphological and functional information in children with congenitally malformed hearts. This progress has come through the development of improved technology such as matrix array probes and software which allows for the off line analysis of images to a high standard. This article focuses on these developments and discusses some newer concepts in advanced echocardiography such is multi-planar reformatting [MPR] and tissue motion annular displacement [TMAD]. Our aim is to discuss important aspects related to the quality and reproducibility of data, to review the most recent published data regarding advanced echocardiography in the malformed heart and to guide the reader to appropriate text for overcoming the technical challenges of using these methods. Many of the technical aspects of image acquisition and post processing have been discussed in recent reviews by the authors and we would urge readers to study these texts to gain a greater understanding [1]. The quality of the two dimensional image is paramount in both strain analysis and three dimensional echocardiography. An awareness of how to improve image quality is vital to acquiring accurate and usable data. Three dimensional echocardiography (3DE) is an attempt to visualise the dynamic morphology of the heart. Although published media is the basis for theoretical knowledge of how to practically acquire images, electronic media [eg.www.3dechocardiography.com] is the only way of visualising the advantages of this technology in real time. It is important to be aware of the limitations of this technology and that much of the data gleaned from using these methods is at a research stage and not yet in regular clinical practice.

    We aimed to evaluate how the presence and severity of congenital heart disease (CHD) influence social life and lifestyle in adult patients. A random sample (n = 1,496) from the CONgenital CORvitia (n = 11,047), the Dutch national registry of adult patients with CHD, completed a questionnaire on educational attainment, employment and marital statuses, and lifestyle (response 76%). The Utrecht Health Project provided a large reference group (n = 6,810) of unaffected subjects. Logistic regression models were used for subgroup analyses and to adjust for age, gender, and socioeconomic status where appropriate. Of all patients 51.5% were men (median age 39 years, interquartile range 29 to 51) with mild (46%), moderate (44%), and severe (10%) CHD. Young (<40-year-old) patients with CHD were more likely to have achieved a lower education (adjusted odds ratios [ORs] 1.6 for men and 1.9 for women, p <0.05 for the 2 comparisons), significantly more often unemployed (adjusted ORs 5.9 and 2.0 for men and women, respectively), and less likely to be in a relationship compared to the reference group (adjusted ORs 8.5 for men and 4.5 for women). These poorer outcomes were seen in all severity groups. Overall, the CHD population smoked less (adjusted OR 0.5, p <0.05), had more sports participation (adjusted OR 1.2, p <0.05), and had less obesity (adjusted OR 0.7, p <0.05) than the reference group. In conclusion, there was a substantial social disadvantage in adult patients with CHD, which was seen in all severity groups and primarily in young men. In contrast, adults with CHD had healthier lifestyles compared to the reference group.

    Adults with congenital heart disease form a new and relatively young population, since surgical treatment of heart defects became available three to four decades ago. Owing to improved survival this population is steadily growing in number and age. Little is known regarding long-term survival; however, late complications occur frequently. During adulthood, almost half of the patients have one or more complication, such as endocarditis, stroke, systemic or pulmonary hypertension, aortic aneurysm or dissection and arrhythmias. Heart failure and sudden cardiac death are the main causes of death. Treatment of adults with congenital heart disease is aimed at the reduction of symptoms, but also at minimizing the risk and severity of late complications. In this article the most recent advances in the treatment of congenital heart disease will be discussed. The main focus of the article will be on pharmacological, interventional and surgical interventions that reduce the risk of heart failure, arrhythmias, vascular complications, pulmonary hypertension and endocarditis.

    Background Understanding the anatomy and physiology of congenital heart defects is crucial for planning interventions in these patients. Congenital heart procedures often involve complex three-dimensional (3D) reconstructions. Excellent imaging techniques are required to depict all anatomical details. We have used and evaluated fast 3D prototyping technology for reconstruction and planning of corrections of complex congenital heart defects. Materials and Methods 3D physical models were constructed from contrast-enhanced computed tomography (CT) datasets of patients with complex congenital heart defect. Two different commercially available printing technologies were used and their clinical application compared. Results Physical models of three different patients were used for preoperative surgical planning. All models showed good correspondence to patient anatomy. Both printing technologies gave excellent results. Conclusion Physical models could be easily constructed with the use of CT datasets. The printing process could be done efficiently, quite rapidly, and cost effectively. Surgical corrections could be planned based on these models.

    Increasing survival rates of patients with congenital heart disease have resulted in a new and growing patient population of adults with operated congenital heart disease. Medical professionals face the specific medical needs of these patients but must also deal with their daily life issues. Adult patients with congenital heart disease report difficulties in several areas of daily life, such as sport, employment, insurability and travel or driving. Moreover, they must have a healthy lifestyle to prevent cardiovascular complications. All these issues can be addressed in a specific educational program. In this review, we discuss the different daily life issues of adults with congenital heart disease and the preventive measures that can be proposed to improve their quality of life.

Patients with congenital heart disease and matched healthy controls were administered classical theory of mind tasks and a semi-structured interview which provides a multidimensional evaluation of theory of mind (Theory of Mind Assessment Scale). The patients with congenital heart disease performed worse than the controls on the Theory of Mind Assessment Scale, whereas they did as well as the control group on the classical theory-of-mind tasks. These findings provide the first evidence that adults with congenital heart disease may display specific impairments in theory of mind.

Objective To investigate the role of MMPs as novel biomarkers in clinically stable adults with congenital heart disease. Methods We measured serum MMP-2, -3, -9 and tissue inhibitor of matrix metalloproteinase-1 in 425 patients and analysed the association with cardiac function and exercise capacity. Results MMP-2 was significantly associated with exercise capacity, ventilatory efficiency and left ventricular deceleration time, independently of age, sex, body surface area and NT-proBNP. Conclusion MMP-2 may provide new information in the clinical evaluation of adults with congenital heart disease.

    As the population of adults with congenital heart disease continues to grow, so does the number of these patients with heart failure. Ventricular assist devices are underutilized in adults with congenital heart disease due to their complex anatomic arrangements and physiology. Advanced imaging techniques that may increase the utilization of mechanical circulatory support in this population must be explored. Three-dimensional printing offers individualized structural models that would enable pre-surgical planning of cannula and device placement in adults with congenital cardiac disease and heart failure who are candidates for such therapies. We present a review of relevant cardiac anomalies, cases in which such models could be utilized, and some background on the cost and procedure associated with this process.

    The surgical treatment of patients with extracardiac structural anomalies and congenital heart disease often carries major risk and remains a challenging field. An appropriate, solid treatment plan should be developed during the early phase with interactive intelligence sharing between a pediatric surgery team and congenital heart surgery team. As the top of the chain of command, the role of a neonatologist is important. This article reviews the history of surgery for congenital heart disease and the progress of the Japan Congenital Cardiovascular Surgery Database. Finally, as an example of a combination of diseases, the clinical course and intelligence sharing during treatment of a patient with biliary atresia requiring living-donor liver transplantation and hypoplastic left heart syndrome is reported. The National Quality Forum provided structural measures, process measures, and outcome measures for congenital heart surgery. Structural measures provided by the National Quality Forum included participation in a preoperative multidisciplinary conference. To improve the outcome of surgical treatment of patients with congenital heart disease and extracardiac structural anomalies, the importance of a preoperative multidisciplinary conference involving not only pediatric surgeons, pediatric cardiologists, and pediatric cardiac surgeons but also neonatologists, anesthesiologists, and nurses cannot be overemphasized.

    Axenfeld-Rieger syndrome is a genetically heterogeneous, autosomal dominant disorder characterized by anomalies of the anterior segment of the eye, face, teeth, and umbilicus. Many other extraocular findings, including congenital heart defects, have been reported in association with this syndrome. It has been suggested by some investigators that the coexistence of Axenfeld-Rieger syndrome and congenital heart defects is not a chance event but it represents a distinct entity. We report a family in which four members in three generations have typical ocular features of Axenfeld-Rieger syndrome. Two of them, who are siblings, also have congenital heart defects. The congenital heart defect was bicuspid aortic valve anomaly with severe stenosis and mild regurgitation in one sibling and ostium secundum atrial septal defect in the other. To our knowledge, the combination of congenital heart defects with Axenfeld-Rieger syndrome in siblings has not been reported previously. Our observation further strengthens the notion that Axenfeld-Rieger syndrome associated with congenital heart defects is not a chance event.

    A larger number of individuals born with congenital heart disease is living into adolescence and young adulthood. With this comes the responsibility to counsel these patients regarding their sexual and reproductive health. This study utilizes representative data from the National Health and Nutrition Examination Survey to compare sexual measures including percentage of that sexually active, age of first sexual activity, number of sexual partners, condom use, and history of sexually transmitted diseases in those with and without congenital heart disease. A total of 1086 patients (1057 without congenital heart disease and 29 with congenital heart disease) were included in this study. Likelihood of being sexually active, age of first sexual intercourse, and condom use did not differ significantly between the two groups after multivariate analysis. Incidence of sexually transmitted disease did not differ between the two groups after multivariate analysis except for genital warts. There are no major differences in sexual measures between those with and without congenital heart disease. The absence of significant differences in sexual measures in those with congenital heart disease compared with the general population places this group of individuals at increased health risk known to occur with pregnancy.

    The prevalence of congenital heart disease among adults in Europe, or in any country in Europe, is not known. This is due to a lack of agreement on the incidence of congenital heart disease, with estimations varying from four per 1000 births to 50 per 1000 births, and it is not known how many patients with congenital heart disease have died. Based on several studies that estimated and calculated the number of adult patients with congenital heart disease, the number of patients should be much higher than the number of patients that are actually seen in specialized centres throughout Europe. This implies that either a large proportion of adult patients with congenital heart disease do not receive appropriate medical care, or that the calculations and estimations are grossly wrong. A combination of the two is also possible. A substantial expansion of the number and size of specialized centres for adult congenital heart disease is advocated, but since setting up (and running) a service for this disease is a costly affair, and because uncertainty remains about the actual number of patients needing specialized care, this has been difficult to realize in most European countries in the past few years.

    We evaluated differences in growth between fetuses with and without congenital heart disease (CHD) and tested associations between growth and early childhood neurodevelopment (ND). In this prospective cohort study, fetuses with hypoplastic left heart syndrome (HLHS), transposition of the great arteries (TGA), and tetralogy of Fallot (TOF) and controls had biparietal diameter (BPD), head (HC) and abdominal circumference (AC), femur length (FL), and estimated fetal weight (EFW) recorded serially during pregnancy at 18and controls were assessed using–26 weeks GA (F1), at 27–33 weeks GA (F2), and at 34–40 weeks GA (F3). CHD subjects underwent Bayley Scales of Infant Development-III ND testing at 18 months. Differences between CHD fetuses and controls were assessed using t tests and generalized linear modeling. Correlations between biometry and ND informed regression modeling. We enrolled 41 controls and 68 fetuses with CHD (N = 24 HLHS, N = 21 TGA, N = 23 TOF), 46 of whom had ND scores available. At 18–26 weeks, CHD fetuses were smaller than controls in all biometric parameters. Differences in growth rates were observed for HC, BPD, and AC, but not for FL or EFW. Cognitive score correlated with HC/AC at F2 (r = −0.33, P = 0.04) and mean HC/AC across gestation (r = −0.35, P = 0.03). Language correlated with FL/BPD at F2 (r = 0.34, P = 0.04). In stepwise linear regression, mean HC/AC predicted Cognition (B = −102, P = 0.026, R2 = 0.13) and FL/BPD at F2 predicted Language score (B = 127, P = 0.03, R2 = 0.12). Differences in growth between CHD fetuses and controls can be measured early in pregnancy. In CHD fetuses, larger abdominal relative to head circumference is associated with better 18-month neurodevelopment. PMID:25753684

    Background Prenatal diagnosis allows for improved peri-operative outcomes of fetuses with certain forms of congenital heart disease (CHD). Variability in prenatal diagnosis has been demonstrated in other countries, leading to efforts to improve fetal imaging protocols and access to care, but has not been examined across the United States. Objective To evaluate national variation in prenatal detection across geographic region and defect type in neonates and infants with CHD undergoing heart surgery. Methods Cardiovascular operations performed in patients ≤ 6 months of age within the United States and included in the STS-CHS Surgical Database (2006–2012) were eligible for inclusion. Centers with >15% missing prenatal diagnosis data were excluded from the study. Prenatal diagnosis rates were compared across geographic location of residence and defect type using the Chi-square test. Results Overall, the study included 31,374 patients from 91 STS-CHS participating centers across the United States. Prenatal detection occurred in 34% and increased every year from 26% (2006) to 42% (2012). There was significant geographic variation in rates of prenatal diagnosis across states (range 11.8 – 53.4%, p < 0.0001). Significant variability by defect type was also observed with higher rates for lesions identifiable on 4-chamber view versus those requiring outflow tract visualization (57% versus 32%, p < 0.0001). Conclusions Rates of prenatal CHD detection in the United States remain low for patients undergoing surgical intervention, with significant variability between states and across defect type. Further studies are needed to identify reasons for this variation and the potential impact on patient outcomes. PMID:26216324

    2016-01-01

    Congenital heart disease (CHD) is the most common type of birth defect. Traditionally, a polygenic model defined by the interaction of multiple genes and environmental factors was hypothesized to account for different forms of CHD. It is now understood that the contribution of genetics to CHD extends beyond a single unified paradigm. For example, monogenic models and chromosomal abnormalities have been associated with various syndromic and non-syndromic forms of CHD. In such instances, genetic investigation and testing may potentially play an important role in clinical care. A family tree with a detailed phenotypic description serves as the initial screening tool to identify potentially inherited defects and to guide further genetic investigation. The selection of a genetic test is contingent upon the particular diagnostic hypothesis generated by clinical examination. Genetic investigation in CHD may carry the potential to improve prognosis by yielding valuable information with regards to personalized medical care, confidence in the clinical diagnosis, and/or targeted patient follow-up. Moreover, genetic assessment may serve as a tool to predict recurrence risk, define the pattern of inheritance within a family, and evaluate the need for further family screening. In some circumstances, prenatal or preimplantation genetic screening could identify fetuses or embryos at high risk for CHD. Although genetics may appear to constitute a highly specialized sector of cardiology, basic knowledge regarding inheritance patterns, recurrence risks, and available screening and diagnostic tools, including their strengths and limitations, could assist the treating physician in providing sound counsel.

    Objectives Congenital heart defects (CHDs) occur in nearly 1% of live births. We sought to assess factors associated with prenatal CHD diagnosis in the National Birth Defects Prevention Study (NBDPS). Methods We analyzed data from mothers with CHD-affected pregnancies from 1998–2005. Prenatal CHD diagnosis was defined as affirmative responses to questions about abnormal prenatal ultrasounds and/or fetal echocardiography obtained during a structured telephone interview. Results Fifteen percent (1,097/7,299) of women with CHD-affected pregnancies (excluding recognized syndromes and single-gene disorders) reported receiving a prenatal CHD diagnosis. Prenatal CHD diagnosis was positively associated with advanced maternal age, family history of CHD, type 1 or type 2 diabetes, twin or higher order gestation, CHD complexity and presence of extracardiac defects. Prenatal CHD diagnosis was inversely associated with maternal Hispanic race/ethnicity, prepregnancy overweight or obesity, and pre-existing hypertension. Prenatal CHD diagnosis varied by time to NBDPS interview and NBDPS study site. Conclusions Further work is warranted to identify reasons for the observed variability in maternal reports of prenatal CHD diagnosis and the extent to which differences in health literacy or health system factors such as access to specialized prenatal care and/or fetal echocardiography may account for such variability.

    Background Chromosomal abnormalities (CAs) are an important cause of congenital heart disease (CHD). Objective Determine the frequency, types and clinical characteristics of CAs identified in a sample of prospective and consecutive patients with CHD. Method Our sample consisted of patients with CHD evaluated during their first hospitalization in a cardiac intensive care unit of a pediatric referral hospital in Southern Brazil. All patients underwent clinical and cytogenetic assessment through high-resolution karyotype. CHDs were classified according to Botto et al. Chi-square, Fisher exact test and odds ratio were used in the statistical analysis (p < 0.05). Results Our sample consisted of 298 patients, 53.4% males, with age ranging from 1 day to 14 years. CAs were observed in 50 patients (16.8%), and 49 of them were syndromic. As for the CAs, 44 (88%) were numeric (40 patients with +21, 2 with +18, 1 with triple X and one with 45,X) and 6 (12%) structural [2 patients with der(14,21), +21, 1 with i(21q), 1 with dup(17p), 1 with del(6p) and 1 with add(18p)]. The group of CHDs more often associated with CAs was atrioventricular septal defect. Conclusions CAs detected through karyotyping are frequent in patients with CHD. Thus, professionals, especially those working in Pediatric Cardiology Services, must be aware of the implications that performing the karyotype can bring to the diagnosis, treatment and prognosis and for genetic counseling of patients and families.

    To establish the prevalence of congenital heart diseases (CHDs) in cleft patients, the type of cleft and the presence of a syndrome were coded in 220 patients. A Doppler echocardiogram with color-flow mapping (DE) was obtained in all patients. Mean age was 112.0 +/- 101.2 months (range, 1-576 months), and 56.8% (125) were males. Cleft lip and palate occurred in 144 patients (65.5%), cleft lip in 40 (18.2%), and cleft palate in 36 (16.4%). Cleft palates were more frequent among females. Twenty-four CHDs were diagnosed in 21 of 220 patients (9.5%): 7 mitral valve prolapses, 6 atrial septal defects, 4 patent ductus arteriosus, 3 ventricular septal defects, 2 cases of tetralogy of Fallot, 1 pulmonary stenosis, and 1 bicuspid aortic valve. The presence of CHD did not correlate with the type of cleft. Syndromes occurred in 28 patients (12.7%), and this association was higher among patients with a cleft palate.

    Little information is available about the transportation costs incurred from the missed prenatal diagnosis of congenital heart disease (CHD). The objectives of the present study were to analyze the costs of emergency transportation related to the postnatal diagnosis of major CHD and to perform a cost/benefit analysis of additional training for ultrasound technicians to study the implications of improved prenatal detection rates. The 1-year costs incurred for emergency transportation of pre- and postnatally diagnosed infants with CHD in Northern California and North Western Nevada were calculated and compared. The prenatal detection rate in our cohort (n = 147) was 30.6%. Infants postnatally diagnosed were 16.5 times more likely (p <0.001) to require emergency transport. The associated emergency transportation costs were US$542,143 in total for all patients with CHD. The mean cost per patient was $389.00 versus $5,143.51 for prenatally and postnatally diagnosed infants, respectively (p <0.001). Assuming an improvement in detection rates after 1-day training for ultrasound technicians, the investment in training cost can be recouped in 1 year if the detection rate increased by 2.4% to 33%. Savings of $6,543,476 would occur within 5 years if the detection rate increased to 50%. In conclusion, CHD diagnosed postnatally results in greater costs related to emergency transportation of ill infants. Improving the prenatal detection rates through improved ultrasound technician training could result in considerable cost savings.

    Newborn screening for critical congenital heart defects (CCHD) was added to the US Recommended Uniform Screening Panel in 2011. Within 4 years, 46 states and the District of Columbia had adopted it into their newborn screening program, leading to CCHD screening being nearly universal in the United States. This rapid adoption occurred while there were still questions about the effectiveness of the recommended screening protocol and barriers to follow-up for infants with a positive screen. In response, the Centers for Disease Control and Prevention partnered with the American Academy of Pediatrics to convene an expert panel between January and September 2015 representing a broad array of primary care, neonatology, pediatric cardiology, nursing, midwifery, public health, and advocacy communities. The panel's goal was to review current practices in newborn screening for CCHD and to identify opportunities for improvement. In this article, we describe the experience of CCHD screening in the United States with regard to: (1) identifying the target lesions for CCHD screening; (2) optimizing the algorithm for screening; (3) determining state-level challenges to implementation and surveillance of CCHD; (4) educating all stakeholders; (5) performing screening using the proper equipment and in a cost-effective manner; and (6) implementing screening in special settings such as the NICU, out-of-hospital settings, and areas of high altitude.

    Clinical congenital anophthalmia is described as the uni- or bilateral absence of the eyeball that might occur in isolation or as part of a syndrome. It has a very low prevalence and its etiology is heterogeneous. Complex congenital cardiac malformations are also rare. The association of congenital anophthalmia and congenital heart disease is rarer still, and the etiology of those associations is not well understood yet. We report the case of a patient who had the very rare association of bilateral anophthalmia, multiple cardiac malformations and severe pulmonary hypertension.

    Background The prevalence of perioperative stroke in infants undergoing operations for congenital heart disease has not been well described. The objectives of this study were to determine the prevalence of stroke as assessed by postoperative brain magnetic resonance imaging (MRI), characterize the neuroanatomic features of focal ischemic injury, and identify risk factors for its development. Methods Brain MRI was performed in 122 infants 3 to 14 days after cardiac operation with cardiopulmonary bypass, with or without deep hypothermic circulatory arrest. Preoperative, intraoperative, and postoperative data were collected. Risk factors were tested by logistic regression for univariate and multivariate associations with stroke. Results Stroke was identified in 12 of 122 patients (10%). Strokes were preoperative in 6 patients and possibly intraoperative or postoperative in the other 6 patients, and were clinically silent except in 1 patient who had clinical seizures. Arterial-occlusive and watershed infarcts were identified with equal distribution in both hemispheres. Multivariate analysis identified lower birth weight, preoperative intubation, lower intraoperative hematocrit, and higher blood pressure at admission to the cardiac intensive care unit postoperatively as significant factors associated with stroke. Prematurity, younger age at operation, duration of cardiopulmonary bypass, and use of deep hypothermic circulatory arrest were not significantly associated with stroke. Conclusions The prevalence of stroke in infants undergoing operations for congenital heart disease was 10%, half of which occurred preoperatively. Most were clinically silent and undetected without neuroimaging. Mechanisms included thromboembolism and hypoperfusion, with patient-specific, procedure-specific, and postoperative contributions to increased risk. PMID:19699905

    Aim: The veterinarian should be able to assess congenital and inherited malformations such as heart defects because they may be object of legal disputes. In this study, the authors report some cases of congenital heart defects in pets (dogs and cats) to clarify whether or not they may be considered a redhibitory defect. Materials and Methods: A total of 28 medical records of pets referred with suspected congenital heart disease were examined. All patients aged between 3 and 24 months underwent clinical examination, chest X-ray examination, electrocardiogram, and echocardiography and angiocardiography when necessary. Results: Congenital heart diseases or associated cardiac malformations were confirmed. Considering the above congenital diseases as redhibitory defect and the rights of the owners from a strictly legal viewpoint, 9 owners demanded an estimatory action and 11 a redhibitory action; 1 owner decided to demand the reimbursement of veterinary expenses because the animal died; 7 owners took no legal action but requested surgical intervention. Conclusions: Until more appropriate and detailed legislation on the buying and selling of pet animals is put in place; the authors propose to include in the contract a temporal extension of the guarantee relating to congenital heart disease, which can often become evident later.

    The strong association between congenital heart disease and spinal deformity is well established, but data on the risks and outcome of spinal fusion surgery in patients with congenital heart disease are scarce. The purpose of this study was to identify predictors of perioperative risk and outcome in a large series of children and adolescents with congenital heart disease who underwent spinal fusion for scoliosis or kyphosis. In the authors' retrospective analysis of 74 consecutive patients with congenital heart disease undergoing spinal fusion, there were two deaths (2.7%) and 18 significant complications (24.3%) in the perioperative period. Preoperative cyanosis (arterial oxygen saturation < 90% at rest) with uncorrected or incompletely corrected congenital heart disease was associated with both deaths. Complications occurred in nine of 18 (50%) patients with cyanosis and in 11 of 56 (20%) patients without cyanosis. As judged by multivariate analysis the best predictors of perioperative outcome were the overall physical status of the patient as represented by the American Society of Anesthesiologists' preoperative score and a higher rate of intraoperative blood loss. Seventeen of 43 patients (40%) with an American Society of Anesthesiologists score of 3 or higher experienced complications including two perioperative deaths. Successful spinal fusion and correction were achieved in 97% of patients. Children and adolescents with congenital heart disease can undergo elective spinal fusion with risks that relate to overall cardiac status. Careful assessment of preoperative status by pediatric cardiologists and cardiac anesthesiologists familiar with surgical treatment of patients with congenital heart disease will assist the orthopaedic surgeon in providing the most realistic estimate of risk.

    Adults with congenital heart disease are a growing population. One of the major challenges in the care of these patients is to prevent thromboembolic episodes. Despite relative young age and no typical cardiovascular risk factors, this cohort has a high prevalence of thrombotic events. It is difficult to use treatment algorithms from the general adult population with acquired heart disease in this heterogeneous population due to special conditions such as myocardial scarring after previous surgery, atypical atrial flutter, prothrombotic conditions and the presence of interatrial shunts. Furthermore, there is a lack of scientific evidence regarding how to prevent thromboembolic events with anticoagulation in adults with congenital heart disease. The aim of this paper is to review the current literature pertaining to anticoagulation in adults with congenital heart disease and hence enable recommendations for which patients are likely to benefit from which anticoagulation treatments, when they should be considered and how these would be carried out.

    Haploinsufficiency of TAB2 was recently implicated as a cause for a variety of congenital heart defects. Reported cases have genomic deletions of 2-10 Mbs including TAB2 at 6q24-25 are almost always de novo and show variable cardiac and extra cardiac phenotype. We report on an inherited, 281 kb deletion in a three generation family. This is the smallest reported deletion involving TAB2 that segregates with congenital heart defects. Three affected individuals in this family present with myxomatous cardiac valves in addition to structural heart defects commonly associated with TAB2 deletions. Findings from this family support a key role of TAB2 haploinsufficiency in congenital heart defects and expand the phenotypic spectrum of TAB2-microdeletion syndrome.

    Twenty patients under the age of 2 years with suspected congenital heart disease received alternately Renografin 76 and metrizamide for angiocardiography. The dose was 2.0 ml/kg per injection for both contrast media into the left ventricle. Metrizamide induced slightly lesser change in heart rate, peak systolic pressure, and peak end-diastolic pressures. Serum osmolality, hematocrit, and serum electrolytes were affected equally by the contrast media. Metrizamide was well tolerated by the neonates with congenital heart disease and its radiopacity was adequate for diagnostic purposes. At the doses administered, metrizamide does not seem to have any great advantage over Renografin 76 for angiocardiography in infants with severe congenital heart disease.

    Sickle cell disease is a risk factor for cerebrovascular accidents in the pediatric population. This risk is compounded by hypoxemia. Cyanotic congenital heart disease can expose patients to prolonged hypoxemia. To our knowledge, the long-term outcome of patients who have combined sickle cell and cyanotic congenital heart disease has not been reported. We retrospectively reviewed patient records at our institution and identified 5 patients (3 girls and 2 boys) who had both conditions. Their outcomes were uniformly poor: 4 died (age range, 12 mo–17 yr); 3 had documented cerebrovascular accidents; and 3 developed ventricular dysfunction. The surviving patient had developmental delays. On the basis of this series, we suggest mitigating hypoxemia, and thus the risk of stroke, in patients who have sickle cell disease and cyanotic congenital heart disease. Potential therapies include chronic blood transfusions, hydroxyurea, earlier surgical correction to reduce the duration of hypoxemia, and heart or bone marrow transplantation. PMID:28100970

    The clinical significance of copy number variants (CNVs) in congenital heart disease (CHD) continues to be a challenge. Although CNVs including genes can confer disease risk, relationships between gene dosage and phenotype are still being defined. Our goal was to perform a quantitative analysis of CNVs involving 100 well-defined CHD risk genes identified through previously published human association studies in subjects with anatomically defined cardiac malformations. A novel analytical approach permitting CNV gene frequency “spectra” to be computed over prespecified regions to determine phenotype-gene dosage relationships was employed. CNVs in subjects with CHD (n = 945), subphenotyped into 40 groups and verified in accordance with the European Paediatric Cardiac Code, were compared with two control groups, a disease-free cohort (n = 2,026) and a population with coronary artery disease (n = 880). Gains (≥200 kb) and losses (≥100 kb) were determined over 100 CHD risk genes and compared using a Barnard exact test. Six subphenotypes showed significant enrichment (P ≤ 0.05), including aortic stenosis (valvar), atrioventricular canal (partial), atrioventricular septal defect with tetralogy of Fallot, subaortic stenosis, tetralogy of Fallot, and truncus arteriosus. Furthermore, CNV gene frequency spectra were enriched (P ≤ 0.05) for losses at: FKBP6, ELN, GTF2IRD1, GATA4, CRKL, TBX1, ATRX, GPC3, BCOR, ZIC3, FLNA and MID1; and gains at: PRKAB2, FMO5, CHD1L, BCL9, ACP6, GJA5, HRAS, GATA6 and RUNX1. Of CHD subjects, 14% had causal chromosomal abnormalities, and 4.3% had likely causal (significantly enriched), large, rare CNVs. CNV frequency spectra combined with precision phenotyping may lead to increased molecular understanding of etiologic pathways. PMID:22318994

    BACKGROUND We investigated the prevalence of receipt of special education services among children with congenital heart defects (CHDs) compared with children without birth defects. METHODS Children born from 1982 to 2004 in metropolitan Atlanta with CHDs (n = 3744) were identified from a population-based birth defect surveillance program; children without birth defects (n = 860 715) were identified from birth certificates. Cohorts were linked to special education files for the 1992–2012 school years to identify special education services. Children with noncardiac defects or genetic syndromes were excluded; children with CHDs were classified by presence or absence of critical CHDs (ie, CHDs requiring intervention by age one year). We evaluated the prevalence of receipt of special education services and prevalence rate ratios using children without birth defects as a reference. RESULTS Compared with children without birth defects, children with CHDs were 50% more likely to receive special education services overall (adjusted prevalence rate ratio [aPRR] = 1.5; 95% confidence interval [CI]: 1.4–1.7). Specifically, they had higher prevalence of several special education categories including: intellectual disability (aPRR = 3.8; 95% CI: 2.8–5.1), sensory impairment (aPRR = 3.0; 95% CI: 1.8–5.0), other health impairment (aPRR = 2.8; 95% CI: 2.2–3.5), significant developmental delay (aPRR = 1.9; 95% CI: 1.3–2.8), and specific learning disability (aPRR = 1.4; 95% CI: 1.1–1.7). For most special education services, the excess prevalence did not vary by presence of critical CHDs. CONCLUSIONS Children with CHDs received special education services more often than children without birth defects. These findings highlight the need for special education services and the importance of developmental screening for all children with CHDs. PMID:26283775

  9. What Is New in Genetics of Congenital Heart Defects?

    Epidemiological studies, clinical observations, and advances in molecular genetics are contributing to the understanding of the etiology of congenital heart defects (CHDs). Several phenotype–genotype correlation studies have suggested that specific morphogenetic mechanisms put in motion by genes can result in a specific cardiac phenotype. The use of new technologies has increased the possibility of identification of new genes and chromosomal loci in syndromic and non-syndromic CHDs. There are a number of methods available for genetic research studies of CHDs, including cytogenetic analysis, linkage and association studies, copy number variation (CNV) and DNA micro-array analysis, and whole exome sequencing. The altered dosage of contiguous genes included inside CNVs can produce new syndromic CHDs, so that several different new genomic conditions have been identified. These include duplication 22q11.2 syndrome, distal 22q11.2 deletion syndrome, deletion and duplication 1q21.1, and deletion 1p36 syndrome. Molecular techniques such as whole exome sequencing have lead to the identification of new genes for monogenic syndromes with CHD, as for example in Adams–Oliver, Noonan, and Kabuki syndrome. The variable expressivity and reduced penetrance of CHDs in genetic syndromes is likely influenced by genetic factors, and several studies have been performed showing the involvement of modifier genes. It is not easy to define precisely the genetic defects underlying non-syndromic CHDs, due to the genetic and clinical heterogeneity of these malformations. Recent experimental studies have identified multiple CNVs contributing to non-syndromic CHD. The number of identified genes for non-syndromic CHDs is at this time limited, and each of the identified genes has been shown to be implicated only in a small proportion of CHD. The application of new technologies to specific cases of CHD and pedigrees with familial recurrence and filtering genes mapping in CNV regions can

    Children with early surgery for congenital heart disease (CHD) are known to have impaired neurodevelopment; their performance on school-age achievement tests and their need for special education remains largely unexplored. The study aimed to determine predictors of academic achievement at school-age and placement in special education services among early CHD surgery survivors. Children with CHD surgery at <1 year of age from 1/1/1998─12/31/2003 at the Arkansas Children’s Hospital were identified. Out-of-state births and infants with known genetic and/or neurologic conditions were excluded. Infants were matched to an Arkansas Department of Education database containing standardized assessments at early school-age and special education codes. Predictors for achieving proficiency in literacy and mathematics and the receipt of special education were determined. 256 children who attended Arkansas public schools and had surgery as infants were included; 77.7% had either school-age achievement-test scores or special education codes of mental retardation or multiple disabilities. Scores on achievement tests for these children were 7–13% lower than Arkansas students (p<0.01). They had an 8-fold increase in the receipt of special education due to multiple disabilities (OR 10.66, 95% CI 4.23─22.35) or mental retardation (OR 4.96, 95% CI 2.6─8.64). Surgery after the neonatal period was associated with reduced literacy proficiency and cardiopulmonary bypass during the first surgery was associated with reduced mathematics proficiency. Children who had early CHD surgery were less proficient on standardized school assessments and many received special education. This is concerning since achievement- test scores at school-age are “real-world” predictors of long-term outcomes. PMID:24000004

    Background Chronic heart failure is an important cause for morbidity and mortality in adults with congenital heart disease (ACHD). While NT-proBNP is an established biomarker for heart failure of non-congenital origin, its value in ACHD has limitations. Asymmetrical dimethylarginine (ADMA) correlates with disease severity and independently predicts adverse clinical events in heart failure of non-congenital origin. Its role in ACHD has not been investigated. Methods In 102 patients ADMA and NT-proBNP were measured and related to NYHA class, systemic ventricular function and parameters of cardiopulmonary exercise testing. Results In contrast to NT-proBNP ADMA differentiated between NYHA classes I-III. Both, ADMA and NT-proBNP showed a good correlation with parameters of cardiopulmonary exercise testing with comparable receiver-operating characteristic curves for identifying patients with severely limited cardiopulmonary exercise capacity. Conclusion ADMA seems to be a better biomarker than NT-proBNP for the assessment of NYHA class and as a good as NT-proBNP for the estimation of maximum exercise capacity in adults with congenital heart disease. Its use in clinical routine should be evaluated. PMID:22470476

    Background: Obesity affects almost one-third of pregnant women and causes many complications, including neural tube defects. It is not clear whether the risk of congenital heart defects, the most common malformations, is also increased. Objective: This study was conducted to determine whether obesity is associated with an increased risk of congenital heart defects. Design: A population-based, nested, case-control study was conducted in infants born with congenital heart defects and unaffected controls from the cohort of all births (n = 1,536,828) between 1993 and 2003 in New York State, excluding New York City. The type of congenital heart defect, maternal body mass index (BMI; in kg/m2), and other risk factors were obtained from the Congenital Malformations Registry and vital records. Mothers of 7392 congenital heart defect cases and 56,304 unaffected controls were studied. Results: All obese women (BMI ≥ 30) were significantly more likely than normal-weight women (BMI: 19–24.9) to have children with a congenital heart defect [odds ratio (OR): 1.15; 95% CI: 1.07, 1.23; P < 0.0001]. Overweight women were not at increased risk (OR: 1.00; 95% CI: 0.94, 1.06). The risk in morbidly obese women (BMI ≥ 40) was higher (OR: 1.33; 95% CI: 1.15, 1.54; P = 0.0001) than that in obese women with a BMI of 30–39.9 (OR: 1.11; 95% CI: 1.04, 1.20; P = 0.004). There was a highly significant trend of increasing OR for congenital heart defects with increasing maternal obesity (P < 0.0001). The offspring of obese women had significantly higher ORs for atrial septal defects, hypoplastic left heart syndrome, aortic stenosis, pulmonic stenosis, and tetralogy of Fallot. Conclusions: Obese, but not overweight, women are at significantly increased risk of bearing children with a range of congenital heart defects, and the risk increases with increasing BMI. Weight reduction as a way to reduce risk should be investigated. PMID:20375192

    Advances in cardiac surgery techniques and early diagnosis have enabled the increased survival of individuals with congenital heart disease. The investigation of the quality of life in children and adolescents with congenital heart disease provides complementary information to clinical data that can assist in decision making on the part of health professionals. Although many studies have been conducted to investigate the quality of life of children and adolescents with congenital heart disease, the results prove to be contradictory; while some studies show that congenital heart disease can impact the quality of life, others describe a better perception of quality of life among children and adolescents who suffer from the disease when compared with healthy control subjects. The purpose of this study is to review the literature on the assessment of health related quality of life in children and adolescents with congenital heart disease, in order to systematize the existing knowledge on this topic today. It is observed that research seeks to investigate aspects of personality in cardiac patients, their coping strategies used and perceived social support, aiming at better understanding the association of these variables with the level of quality of life in this population.

    The incidence of congenital heart diseases accounts for 8-10 over 1000 liveborn. In Italy about 4000-4500 babies each year are born with congenital heart diseases; 50% of those babies (2000-2200) need cardiac surgery shortly after birth or within the first few months of life. Of the remaining 50%, half undergoes cardiac surgery later on in life and half does not necessitate any surgery; 30% of all cardiac operations consist of palliative procedures and the remaining 70% consist of one-stage corrective procedures. Improvements achieved both in surgical and anesthesiologic techniques, and in cardiopulmonary bypass and myocardial protection, have led to better results in pediatric cardiac surgery, with excellent long term survival rate, even for the more complex variants of congenital heart malformations. Therefore anesthesiologists are now more often required to deal with patients affected by congenital heart defects, for other than cardiac problems. Accurate investigation of patient's clinical history is strongly suggested. Moreover knowledge and familiarity with the modifications of the physiology, occurring in congenital heart disease patients, are mandatory for the choice of the more appropriate anesthesiologic strategy for each patient, in order to optimise the risk-benefits ratio and achieve a less traumatic impact on the cardio-circulatory and respiratory equilibrium. With the aim of achieving better results, interaction between anesthesiologist, cardiologist, pediatrician, surgeon and sometime neonatologist and cardiac surgeon, is strongly recommended in the evaluation of risks, and in decision making of strategies and timing of treatment.

    Introduction: Hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. Sensory-neural hearing loss (SNHL) accounts for more than 90% of all hearing loss. This disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. Given that congenital heart diseases are life-threatening, we decided to study the frequency of congenital heart diseases in children with congenital sensory-neural deafness. Materials and Methods: All children who had undergone cochlear implantation surgery due to SNHL and who had attended our hospital for speech therapy during 2008–2011 were evaluated by Doppler echocardiography. Results: Thirty-one children (15 boys and 16 girls) with a mean age of 55.70 months were examined, and underwent electrocardiography (ECG) and echocardiography. None of the children had any signs of heart problems in their medical records. Most of their heart examinations were normal, one patient had expiratory wheeze, four (12%) had mid-systolic click, and four (12%) had an intensified S1 sound. In echocardiography, 15 children (46%) had mitral valve prolapse (MVP) and two (6%) had minimal mitral regurgitation (MR). Mean ejection fraction (EF) was 69% and the mean fractional shortening (FS) was 38%. Conclusion: This study indicates the need for echocardiography and heart examinations in children with SNHL.

    There are 16.5 million newborns in China annually. However, the incidence of congenital heart disease (CHD) has not been evaluated. In 2004, we launched an active province-wide hospital-based CHD registry in the Guangdong Province of southern China. In this study, we examined the incidence of CHD and its subtypes from 2004 to 2012 and compared our findings to the literature. Our results indicate there is an increasing trend of CHD incidence. The increase in incidence occurred mainly for single lesion and the most common subtypes (e.g., ventricular or atrial septal defect, patent ductus arteriosus). There were no increases found for multiple lesions or more complex subtypes. The proportion of CHD cases that were detected early (e.g., 1 week) increased over time. The incidence of CHD stabilized in 2010–2012 with the average cumulative incidences of 9.7, 9.9, and 11.1 per 1,000 live births at 1 week, 1 month, and 1 year, respectively. The incidences of CHD subtypes were comparable with recent international results. The data did not support previous reports that Asian children have a higher incidence of pulmonary outflow obstructions and lower incidence of transposition of the great arteries. However, there was a lower incidence of left ventricular outflow tract obstructions observed in our series. The increase in CHD incidence observed over time was due to improved detection and diagnosis. The true incidence of CHD in China was approximately 11.1 per 1,000 live births, which is higher than previously reported. PMID:27409588

    Objectives The purpose of this study was to estimate the prevalence of major and minor congenital heart defects among fetuses and neonates using sonography in a general population of 4 areas surrounding Shanghai, China. Methods Pregnant women were recruited between April 2004 and December 2005 in Jiaxing City, Suzhou City, Changshu County, and Haining County. All participants could have 3 sonographic examinations performed by specially trained physicians regardless of medical indication: a fetal sonographic screen and fetal echocardiography between 20 and 28 weeks’ gestation and neonatal echocardiography. Diagnoses of congenital heart defects were made on the basis of review of all available scans by an international group of experts in pediatric cardiology. Prevalence rates were calculated per 1000 births. Results Among 4006 scanned fetuses and neonates, there were 75 congenital heart defects, including 12 major defects. The observed prevalence for all congenital heart defects was 18.7 (95% confidence interval, 14.8–23.5) per 1000 births, and the prevalence for major defects was 3.0 (95% confidence interval, 1.6–5.2) per 1000 births. The most common defects were ventricular septal defects (n = 47 [62.7%]), atrial septal defects (n = 14 [18.7%]), tetralogy of Fallot (n = 4 [5.3%]), and hypoplastic left heart syndrome (n = 3 [4.0%]). Conclusions The prevalence of all congenital heart defects in the 4 areas of China studied was higher than that reported in other countries, with ventricular septal defects being the most frequent defects. Our data likely reflect a better estimate of the total prevalence of congenital heart defects in China than reported previously. PMID:21705732

    Pioneers in congenital heart surgery observed that exercise capacity did not return to normal levels despite successful surgical repair, leading some to cite a "myocardial factor" playing a role. They conjectured that residual alterations in myocardial function would be significant for patients' long-term outlook. In fulfillment of their early observations, today's adult congenital heart disease (ACHD) population shows well-recognized features of heart failure, even among patients without clear residual anatomic or hemodynamic abnormalities, demonstrating the vital role of the myocardium in their morbidity and mortality. Whereas the 'myocardial factor' was an elusive concept in the early history of congenital heart care, we now have imaging techniques to detect and quantify one such factor--myocardial fibrosis. Understanding the importance of myocardial fibrosis as a final common pathway in a variety of congenital lesions provides a framework for both the study and treatment of clinical heart failure in this context. While typical heart failure pharmacology should reduce or attenuate fibrogenesis, efforts to show meaningful improvements with standard pharmacotherapy in ACHD repeatedly fall short. This paper considers the importance of myocardial fibrosis and function, the current body of evidence for myocardial fibrosis in ACHD, and its implications for research and treatment.

    IMPORTANCE Critical congenital heart disease (CCHD) was added to the Recommended Uniform Screening Panel for Newborns in the United States in 2011. Many states have recently adopted or are considering requirements for universal CCHD screening through pulse oximetry in birth hospitals. Limited previous research is directly applicable to the question of how many US infants with CCHD might be identified through screening. OBJECTIVES To estimate the proportion of US infants with late detection of CCHD (>3 days after birth) based on existing clinical practice and to investigate factors associated with late detection. DESIGN, SETTING, AND PARTICIPANTS Descriptive and multivariable analysis. Data were obtained from a multisite population-based study of birth defects in the United States, the National Birth Defects Prevention Study (NBDPS). We included all live-born infants with estimated dates of delivery from January 1, 1998, through December 31, 2007, and nonsyndromic, clinically verified CCHD conditions potentially detectable through screening via pulse oximetry. MAIN OUTCOMES AND MEASURES The main outcome measure was the proportion of infants with late detection of CCHD through echocardiography or at autopsy under the assumption that universal screening at birth hospitals might reduce the number of such late diagnoses. Secondary outcome measures included prevalence ratios for associations between selected demographic and clinical factors and late detection of CCHD. RESULTS Of 3746 live-born infants with nonsyndromic CCHD, late detection occurred in 1106 (29.5% [95%CI, 28.1%–31.0%]), including 6 (0.2%) (0.1% –0.4%) first receiving a diagnosis at autopsy more than 3 days after birth. Late detection varied by CCHD type from 9 of 120 infants (7.5%[95%CI, 3.5%–13.8%]) with pulmonary atresia to 497 of 801 (62.0% [58.7%–65.4%]) with coarctation of the aorta. In multivariable analysis, late detection varied significantly by CCHD type and study site, and infants with

    Cardiopulmonary bypass (CPB) in pediatric cardiac surgery is generally performed with hypothermia, flow reduction and hemodilution. From October 2013 to December 2014, 55 patients, median age 6 years (range 2 months to 52 years), median weight 18.5 kg (range 3.2–57 kg), underwent surgery with normothermic high flow CPB in a new unit. There were no early or late deaths. Fifty patients (90.9%) were extubated within 3 h, 3 (5.5%) within 24 h, and 2 (3.6%) within 48 h. Twenty-four patients (43.6%) did not require inotropic support, 31 (56.4%) received dopamine or dobutamine: 21 ≤5 mcg/kg/min, 8 5–10 mcg/kg/min, and 2 >10 mcg/kg/min. Two patients (6.5%) required noradrenaline 0.05–0.1 mcg/kg/min. On arrival to ICU and after 3 and 6 h and 8:00 a.m. the next morning, mean lactate levels were 1.9 ± 09, 2.0 ± 1.2, 1.6 ± 0.8, and 1.4 ± 0.7 mmol/L (0.6–5.2 mmol/L), respectively. From arrival to ICU to 8:00 a.m. the next morning mean urine output was 3.8 ± 1.5 mL/kg/h (0.7–7.6 mL/kg/h), and mean chest drainage was 0.6 ± 0.5 mL/kg/h (0.1–2.3 mL/kg/h). Mean ICU and hospital stay were 2.7 ± 1.4 days (2–8 days) and 7.2 ± 2.2 days (4–15 days), respectively. In conclusion, normothermic high flow CPB allows pediatric and congenital heart surgery with favorable outcomes even in a new unit. The immediate post-operative period is characterized by low requirement for inotropic and respiratory support, low lactate production, adequate urine output, minimal drainage from the chest drains, short ICU, and hospital stay.

    To provide an overview of the epidemiology of congenital heart disease, the results of epidemiological studies done in 4 regions of Saudi Arabia (August 1988-February 2000) and 2604 individuals with congenital heart disease were evaluated. Ventricular septal defect was the commonest lesion (33.9%) followed by atrial septal defect (18.1%). Overall, sex distribution was similar; for 3 conditions, more males than females were affected. Of 2269 (59%) presenting in the first year of life, 566 (24.9%) had neonatal congenital heart disease. Down syndrome was the commonest cause. Distribution of specific lesions and sex distribution was similar to findings from other parts of the world; however, the overall detection rate at 1 year of age was lower.

    Down syndrome (DS) is a major cause of congenital heart and gut disease and mental retardation. DS individuals also have characteristic facies, hands, and dermatoglyphics, in addition to abnormalities of the immune system, and increased risk of leukemia, and an Alzheimer-like dementia. Although their molecular basis is unknown, recent work on patients with DS and partial duplications of chromosome 21 has suggested small chromosomal regions located in band q22 that are likely to contain the genes for some of these features. The authors now extend these analyses to define molecular markers for the congenital heart disease, the duodenal stenosis, and an 'overlap' region for the facial and some of the skeletal features. They report the clinical, cytogenetic, and molecular analysis of two patients. These studies provide the molecular basis for the construction of a DS phenotypic map and focus the search for genes responsible for the physical features, congenital heart disease, and duodenal stenosis of DS.

    A neonate with a double aneuploidy associated with congenital heart defect (CHD) suffered from cyanosis after birth. He had typical features of Down syndrome (DS) including hypertelorism, slightly lowset ears with protruding pinna. Doppler echocardiography indicated complex congenital heart disease with an ostium secundum atrial septal defect, enlarged right ventricle, and mild tricuspid valve regurgitation. Further chromosomal analysis showed a karyotype of 48,XXY,+21: a double aneuploidy of DS and Klinefelter syndrome (KS). Until now, only seven cases of double aneuploidy associated with CHD defect have been reported. PMID:24778570

    Based on the sequentiality principle, this review proposes a practical method that allows the systematization of the anatomic diagnosis of congenital heart disease. We emphasize the need to use sequential connection between the different cardiac segments: atria, ventricles and great arteries. Five ordered steps are defined, which include determination of atrial situs and of the connection features between the ventricles and the great arteries. Related lesions and some additional special features are a second stage in the sequential analysis of congenital heart disease, which is also important for the integral diagnosis.

    Over the last 25 years, the Congenital Heart Surgeons Society (CHSS) has evolved from an informal club to a mature organization. A central feature of the CHSS has been dedication to evaluating outcomes of congenital heart surgery across a wide array of clinical diagnoses. These research activities have been orchestrated through the CHSS Datacenter, which has developed a unique organizational structure that has strengths and weaknesses in comparison to other research organizational structures (e.g., prospective randomized trials, registries, etc). This review will highlight the unique attributes of the CHSS Datacenter with emphasis on the Datacenter's strengths and weaknesses in comparison to other organizational structures.

    More than 90% of children born with congenital heart disease survive into adulthood due to successes of cardiac surgery and medical management. Interviews with 16 young adults with congenital heart disease to explore their experiences of transfer from pediatric to adult care were performed. The analysis identified five themes; Feeling secure during the transfer process, Experiencing trust in the care, Expecting to be involved, Assuming responsibility for one's health is a process and Lack of knowledge leads to uncertainty. In conclusion; a structured and gradual transfer process was necessary to enable the informants to shoulder the responsibility for self-care.

    Alcohol-induced congenital heart defects are frequently among the most life threatening and require surgical correction in newborns. The etiology of these defects, collectively known as fetal alcohol syndrome, has been the focus of much study, particularly involving cellular and molecular mechanisms. Few studies have addressed the influential role of altered cardiac function in early embryogenesis because of a lack of tools with the capability to assay tiny beating hearts. To overcome this gap in our understanding, we used optical coherence tomography (OCT), a nondestructive imaging modality capable of micrometer-scale resolution imaging, to rapidly and accurately map cardiovascular structure and hemodynamics in real time under physiological conditions. In this study, we exposed avian embryos to a single dose of alcohol/ethanol at gastrulation when the embryo is sensitive to the induction of birth defects. Late-stage hearts were analyzed using standard histological analysis with a focus on the atrio-ventricular valves. Early cardiac function was assayed using Doppler OCT, and structural analysis of the cardiac cushions was performed using OCT imaging. Our results indicated that ethanol-exposed embryos developed late-stage valvuloseptal defects. At early stages, they exhibited increased regurgitant flow and developed smaller atrio-ventricular cardiac cushions, compared with controls (uninjected and saline-injected embryos). The embryos also exhibited abnormal flexion/torsion of the body. Our evidence suggests that ethanol-induced alterations in early cardiac function have the potential to contribute to late-stage valve and septal defects, thus demonstrating that functional parameters may serve as early and sensitive gauges of cardiac normalcy and abnormalities.

    Several chronic diseases are known to negatively affect the ability of an individual to perform exercise. However, the altered exercise capacity observed in these patients is not solely associated with the heart and lungs dysfunction. Exercise has also been shown to play an important role in the management of several pathologies encountered in the fields of cardiology and pneumology. Studies conducted in our institution regarding the influence of diabetes, chronic heart failure, congenital heart disease and chronic pulmonary obstructive disease on the acute and chronic exercise responses, along with the beneficial effects of exercise training in these populations, are reviewed.

    With advances in pediatric cardiology and cardiac surgery, the population of adults with congenital heart disease (CHD) has increased. In the current era, there are more adults with CHD than children. This population has many unique issues and needs. They have distinctive forms of heart failure and their cardiac disease can be associated with pulmonary hypertension, thromboemboli, complex arrhythmias and sudden death. Medical aspects that need to be considered relate to the long-term and multisystemic effects of single ventricle physiology, cyanosis, systemic right ventricles, complex intracardiac baffles and failing subpulmonary right ventricles. Since the 2001 Canadian Cardiovascular Society Consensus Conference report on the management of adults with CHD, there have been significant advances in the field of adult CHD. Therefore, new clinical guidelines have been written by Canadian adult CHD physicians in collaboration with an international panel of experts in the field. Part III of the guidelines includes recommendations for the care of patients with complete transposition of the great arteries, congenitally corrected transposition of the great arteries, Fontan operations and single ventricles, Eisenmenger's syndrome, and cyanotic heart disease. Topics addressed include genetics, clinical outcomes, recommended diagnostic workup, surgical and interventional options, treatment of arrhythmias, assessment of pregnancy risk and follow-up requirements. The complete document consists of four manuscripts, which are published online in the present issue of The Canadian Journal of Cardiology.

    This review discusses the historical aspects, current state of the art, and potential future advances in the areas of nomenclature and databases for congenital heart disease. Five areas will be reviewed: (1) common language = nomenclature, (2) mechanism of data collection (database or registry) with an established uniform core data set, (3) mechanism of evaluating case complexity, (4) mechanism to ensure and verify data completeness and accuracy, and (5) collaboration between medical subspecialties. During the 1990s, both the Society of Thoracic Surgeons (STS) and the European Association for Cardiothoracic Surgery (EACTS) created congenital heart surgery outcomes databases. Beginning in 1998, the EACTS and STS collaborated in the work of the International Congenital Heart Surgery Nomenclature and Database Project. By 2000, a common congenital heart surgery nomenclature, along with a common core minimal data set, were adopted by the EACTS and the STS and published in the Annals of Thoracic Surgery. In 2000, the International Nomenclature Committee for Pediatric and Congenital Heart Disease was established; this committee eventually evolved into the International Society for Nomenclature of Paediatric and Congenital Heart Disease (ISNPCHD). The working component of ISNPCHD is the International Working Group for Mapping and Coding of Nomenclatures for Paediatric and Congenital Heart Disease, also known as the Nomenclature Working Group (NWG). By 2005, the NWG cross-mapped the EACTS-STS nomenclature with the European Paediatric Cardiac Code of the Association for European Paediatric Cardiology and created the International Paediatric and Congenital Cardiac Code (IPCCC) ( http://www.IPCCC.NET ). This common nomenclature (IPCCC), and the common minimum database data set created by the International Congenital Heart Surgery Nomenclature and Database Project, are now utilized by both EACTS and STS; since 1998, this nomenclature and database have been used by both the STS

    2015-01-01

    This review article reports on the new field of stem cell therapy and tissue engineering and its potential on the management of congenital heart disease. To date, stem cell therapy has mainly focused on treatment of ischemic heart disease and heart failure, with initial indication of safety and mild-to-moderate efficacy. Preclinical studies and initial clinical trials suggest that the approach could be uniquely suited for the correction of congenital defects of the heart. The basic concept is to create living material made by cellularized grafts that, once implanted into the heart, grows and remodels in parallel with the recipient organ. This would make a substantial improvement in current clinical management, which often requires repeated surgical corrections for failure of implanted grafts. Different types of stem cells have been considered and the identification of specific cardiac stem cells within the heterogeneous population of mesenchymal and stromal cells offers opportunities for de novo cardiomyogenesis. In addition, endothelial cells and vascular progenitors, including cells with pericyte characteristics, may be necessary to generate efficiently perfused grafts. The implementation of current surgical grafts by stem cell engineering could address the unmet clinical needs of patients with congenital heart defects. PMID:26176009

    The number of recreational scuba divers is steadily increasing. In its latest recommendations, the French Federation of Undersea Studies and Sports listed congenital heart disease as a formal and final contraindication to scuba diving. On the other hand, with the progress made in their management, the prognosis and quality of life of patients with congenital heart diseases have improved considerably, enabling them to engage in physical and sports endeavours, which are known to confer general health and psychological benefits. As a consequence, the ability of these patients to dive has become a regular and recurrent issue. We review the various types of scuba diving, the physical performance required for its practice, its effects on cardiovascular function and the elements that need to be considered before recommending whether it can be practiced safely at various levels of difficulty. Because of the diversity and broad heterogeneity of congenital heart diseases, a detailed evaluation of each patient's performance based on clinical criteria common to all congenital heart diseases is recommended.

    Prostaglandin E1 is crucial for keeping the patent ductus arteriosus in critical congenital heart disease for the survival and palliation of particularly prematurely born babies until a cardiosurgical intervention is available. In this study, the side effects of prostaglandin E1 in newborns with critical congenital heart disease and clinical outcomes were evaluated. Thirty-five newborns diagnosed with critical congenital heart disease were treated with prostaglandin E1 between January 2012 and September 2014 at our hospital. Patient charts were examined for prostaglandin E1 side effects (metabolic, gastric outlet obstruction, apnea), clinical status, and prognosis. Acquired data were analyzed in the SPSS 20.0 program. Patients with birth weight under 2500 g needed more days of prostaglandin E1 infusion than ones with birthweight over 2500 g (P = 0.016). The ratio of patients with birth weight under 2500 g who received prostaglandin E1 longer than 7 days was higher than the patients with birth weight over 2500 g (P = 0.02). Eighteen side effects were encountered in 11 of 35 patients (31%). Of these side effects, 1 patient had 4, 4 patients had 2, and 6 patients had only 1 side effect. Discontinuation of the therapy was never needed. Prostaglandin E1 is an accepted therapy modality for survival and outcome in critical congenital heart disease in particularly low-birth-weight babies until a surgical intervention is available. Side effects are not less encountered but are almost always manageable, and discontinuation is not needed.

    Owing to improved surgical results, there is a growing population of patients with repaired congenital heart disease (CHD) requiring heart transplantation. The objective of the study was to review our experience in these patients. A retrospective review of the outcomes of heart transplantation in patients with CHD (n = 77) between 1988 and 2014 was performed. Outcomes of early (1988-1999) and late (2000-2014) eras were compared. In results, the mean age was 18 ± 14 years (range: 16 days-58 years). Seventy (91%) patients underwent a mean of 2.6 ± 1.3 (range: 1-6) cardiac operations before transplantation, whereas 7 were primary transplants. Univentricular palliation had been performed in 44 (57%) patients. Patients with CHD in the later era had longer mean cardiopulmonary bypass time (early: 190 ± 70 minute vs late: 271 ± 115 minute; P < 0.001), ischemic times (early: 222 ± 98 minute vs late: 275 ± 102 minute; P = 0.039), and more often required reconstruction of the great arteries at the time of transplantation (8% vs 28%; P = 0.036). In those with prior univentricular palliations, the ratio of ischemic to cardiopulmonary bypass time decreased in the later era (early: 1.41 ± 0.60 vs late: 0.99 ± 0.37; P = 0.016), reflecting increased intraoperative complexity. Following transplantation, hospital mortality was 13% (10/77; 7 due to primary graft failure). There was no difference in inhospital mortality between the 2 eras (P = 0.52); however, patients in the later era more often required postoperative extracorporeal membrane oxygenation (early: 8%, 3/38 vs late: 28%, 11/39; P = 0.036). In patients with prior univentricular palliations, those in the late era were more likely to experience postoperative renal impairment (early: 1/21, 5% vs late: 9/23, 39%; P = 0.01). Patients with CHD had higher 30-day mortality (CHD: n = 8, 10% vs non-CHD: n = 17, 3.8%; P = 0.021), but similar survival at 10 years (67% ± 12% vs 70% ± 4.7%; P = 0.87) compared to those without

  6. Relation of milrinone after surgery for congenital heart disease to significant postoperative tachyarrhythmias.

    2011-12-01

    Milrinone reduces the risk of low cardiac output syndrome for some pediatric patients after congenital heart surgery. Data from adults undergoing cardiac surgery suggest an association between milrinone and an increased risk of postoperative arrhythmias. We tested the hypothesis that milrinone is an independent risk factor for tachyarrhythmias after congenital heart surgery. Subjects undergoing congenital heart surgery at our institution were consecutively enrolled for 38 months, through September 2010. The data were prospectively collected, including a review of full-disclosure telemetry and the medical records. Within 38 months, 603 enrolled subjects underwent 724 operative procedures. The median age was 5.5 months (range 0.0 to 426), the median weight was 6.0 kg (range 0.7 to 108), and the cohort was 45% female. The overall arrhythmia incidence was 50%, most commonly monomorphic ventricular tachycardia (n = 85, 12%), junctional ectopic tachycardia (n = 69, 10%), accelerated junctional rhythm (n = 58, 8%), and atrial tachyarrhythmias (including atrial fibrillation, atrial flutter, and ectopic or chaotic atrial tachycardia, n = 58, 8%). Multivariate logistic regression analysis demonstrated that independent of age <1 month, the use of cardiopulmonary bypass, the duration of cardiopulmonary bypass, Risk Adjusted classification for Congenital Heart Surgery, version 1, score >3, and the use of epinephrine or dopamine, milrinone use on admission to the cardiac intensive care unit remained independently associated with an increase in the odds of postoperative tachyarrhythmia resulting in an intervention (odds ratio 2.8, 95% confidence interval 1.3 to 6.0, p = 0.007). In conclusion, milrinone use is an independent risk factor for clinically significant tachyarrhythmias in the early postoperative period after congenital heart surgery.

    Infants with complex congenital heart disease are at high risk for poor neurodevelopmental outcomes. However, implementation of dedicated congenital heart disease follow-up programs presents important infrastructure, personnel, and resource challenges. We present the development, implementation, and retrospective review of 1- and 2-year outcomes of a Complex Congenital Heart Defect Neurodevelopmental Follow-Up program. This program was a synergistic approach between the Pediatric Cardiology, Cardiothoracic Surgery, Pediatric Intensive Care, and Neonatal Intensive Care Unit Follow-Up teams to provide a feasible and responsible utilization of existing infrastructure and personnel, to develop and implement a program dedicated to children with congenital heart disease. Trained developmental testers administered the Ages and Stages Questionnaire-3 over the phone to the parents of all referred children at least once between 6 and 12 months’ corrected age. At 18 months’ corrected age, all children were scheduled in the Neonatal Intensive-Care Unit Follow-Up Clinic for a visit with standardized neurological exams, Bayley III, multidisciplinary therapy evaluations and continued follow-up. Of the 132 patients identified in the Cardiothoracic Surgery database and at discharge from the hospital, a total number of 106 infants were reviewed. A genetic syndrome was identified in 23.4% of the population. Neuroimaging abnormalities were identified in 21.7% of the cohort with 12.8% having visibly severe insults. As a result, 23 (26.7%) received first-time referrals for early intervention services, 16 (13.8%) received referrals for new services in addition to their existing ones. We concluded that utilization of existing resources in collaboration with established programs can ensure targeted neurodevelopmental follow-up for all children with complex congenital heart disease.

    The identification and characterization of the cellular and molecular pathways involved in the differentiation and morphogenesis of specific cell types of the developing heart are crucial to understanding the process of cardiac development and the pathology associated with human congenital heart disease. Here, we show that the cardiac transcription factor CASTOR (CASZ1) directly interacts with congenital heart disease 5 protein (CHD5), which is also known as tryptophan-rich basic protein (WRB), a gene located on chromosome 21 in the proposed region responsible for congenital heart disease in individuals with Down's syndrome. We demonstrate that loss of CHD5 in Xenopus leads to compromised myocardial integrity, improper deposition of basement membrane, and a resultant failure of hearts to undergo cell movements associated with cardiac formation. We further report that CHD5 is essential for CASZ1 function and that the CHD5-CASZ1 interaction is necessary for cardiac morphogenesis. Collectively, these results establish a role for CHD5 and CASZ1 in the early stages of vertebrate cardiac development.

    Cardiovascular magnetic resonance (CMR) has expanded its role in the diagnosis and management of congenital heart disease (CHD) and acquired heart disease in pediatric patients. Ongoing technological advancements in both data acquisition and data presentation have enabled CMR to be integrated into clinical practice with increasing understanding of the advantages and limitations of the technique by pediatric cardiologists and congenital heart surgeons. Importantly, the combination of exquisite 3D anatomy with physiological data enables CMR to provide a unique perspective for the management of many patients with CHD. Imaging small children with CHD is challenging, and in this article we will review the technical adjustments, imaging protocols and application of CMR in the pediatric population. PMID:21936913

    An improved understanding of the roles of hemodynamic forces play in cardiac development and the pathogenesis of cardiac disease will have significant scientific and clinical impact. I will focus on the role of fluid dynamics in congenital heart disease and aortic valve calcification. Congenital heart defects are the most common form of birth defect. Aortic valve calcification/stenosis is the third leading cause of adult heart disease and the most common form of acquired valvular disease in developed countries. Given the high incidence of these diseases and their associated morbidity and mortality, the potential translational impact of an improved understanding of cardiac hemodynamic forces is very large.

    To investigate the application and effectiveness of vascular corrosion technique in preparing fetal cardiovascular cast models, 10 normal fetal heart specimens with other congenital disease (control group) and 18 specimens with severe congenital heart disease (case group) from induced abortions were enrolled in this study from March 2013 to June 2015 in our hospital. Cast models were prepared by injecting casting material into vascular lumen to demonstrate real geometries of fetal cardiovascular system. Casting effectiveness was analyzed in terms of local anatomic structures and different anatomical levels (including overall level, atrioventricular and great vascular system, left-sided and right-sided heart), as well as different trimesters of pregnancy. In our study, all specimens were successfully casted. Casting effectiveness analysis of local anatomic structures showed a mean score from 1.90±1.45 to 3.60±0.52, without significant differences between case and control groups in most local anatomic structures except left ventricle, which had a higher score in control group (P=0.027). Inter-group comparison of casting effectiveness in different anatomical levels showed no significant differences between the two groups. Intra-group comparison also revealed undifferentiated casting effectiveness between atrioventricular and great vascular system, or left-sided and right-sided heart in corresponding group. Third-trimester group had a significantly higher perfusion score in great vascular system than second-trimester group (P=0.046), while the other anatomical levels displayed no such difference. Vascular corrosion technique can be successfully used in fabrication of fetal cardiovascular cast model. It is also a reliable method to demonstrate three-dimensional anatomy of severe congenital heart disease and normal heart in fetus.

    Interventional cardiology for paediatric and congenital cardiac disease is a relatively young and rapidly evolving field. As the profession begins to establish multi-institutional databases, a universal system of nomenclature is necessary for the field of interventional cardiology for paediatric and congenital cardiac disease. The purpose of this paper is to present the results of the efforts of The International Society for Nomenclature of Paediatric and Congenital Heart Disease to establish a system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease, focusing both on procedural nomenclature and on the nomenclature of complications associated with interventional cardiology. This system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease is a component of The International Paediatric and Congenital Cardiac Code. This manuscript is the first part of a two-part series. Part 1 will cover the procedural nomenclature associated with interventional cardiology as treatment for paediatric and congenital cardiac disease. This procedural nomenclature of The International Paediatric and Congenital Cardiac Code will be used in the IMPACT Registry™ (IMproving Pediatric and Adult Congenital Treatment) of the National Cardiovascular Data Registry® of The American College of Cardiology. Part 2 will cover the nomenclature of complications associated with interventional cardiology as treatment for paediatric and congenital cardiac disease.

  13. Grown-up congenital heart (GUCH) disease: current needs and provision of service for adolescents and adults with congenital heart disease in the UK

    PubMed Central

    2002-01-01

    The size of the national population of patients with grown-up congenital heart disease (GUCH) is uncertain, but since 80–85% of patients born with congenital heart disease now survive to adulthood (age 16 years), an annual increase of 2500 can be anticipated according to birth rate. Organisation of medical care is haphazard with only three of 18 cardiac surgical centres operating on over 30 cases per annum and only two established specialised units fully equipped and staffed. Not all grown-ups with congenital heart disease require the same level of expertise; 20–25% are complex, rare, etc, and require life long expert supervision and/or intervention; a further 35–40% require access to expert consultation. The rest, about 40%, have simple or cured diseases and need little or no specialist expertise. The size of the population needing expertise is small in comparison to coronary and hypertensive disease, aging, and increasing in complexity. It requires expert cardiac surgery and specialised medical cardiology, intensive care, electrophysiology, imaging and interventions, "at risk" pregnancy services, connection to transplant services familiar with their basic problem, clinical nurse specialist advisors, and trained nurses. An integrated national service is described with 4–6 specialist units established within adult cardiology, ideally in relation or proximity to university hospital/departments in appropriate geographic location, based in association with established paediatric cardiac surgical centres with designated inpatient and outpatient facilities for grown-up patients with congenital heart disease. Specialist units should accept responsibility for educating the profession, training the specialists, cooperative research, receiving patients "out of region", sharing particular skills between each other, and they must liaise with other services and trusts in the health service, particularly specified outpatient clinics in district and regional centres.

    Congenital heart defects (CHD) are the cause of reduced physical performance. The presence of congenital abnormalities in the heart of grown-up patients contributes to excessive hypo-kinesia. We present endurance parameters and a personalized comprehensive cardiac rehabilitation program before an extreme mountain climbing of a 27-year-old patient with an uncorrected ventricular septal defect (VSD). A 26-year-old female patient with an uncorrected congenital VSD was admitted to the department of cardiac rehabilitation before the planned high-mountain expedition. Professional preparation and assessment of actual exercise capacity was performed before scheduled extreme climbing. We conclude that physical activity associated with a heavy load in people with uncorrected CHD who have not developed pulmonary hypertension and reverse right-to-left flow seems to be safe, while participation of grown-up patients with congenital heart disease (GUCH) in extreme mountain climbing requires special preparation, individually designed endurance training and education program, conducted by the team of professionals in specialist centers.

    The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS CHSD) is the largest congenital and pediatric cardiac surgical clinical data registry in the world. With more than 400,000 total operations from nearly all centers performing pediatric and congenital heart operations in North America, the STS CHSD is an unparalleled platform for clinical investigation, outcomes research, and quality improvement activities in this subspecialty. In 2015, several major original publications reported analyses of data in the CHSD pertaining to specific diagnostic and procedural groups, age-defined cohorts, or the entire population of patients in the database. Additional publications reported the most recent development, evaluation, and application of metrics for quality measurement and reporting of pediatric and congenital heart operation outcomes. This use of the STS CHSD for outcomes research and for quality measurement continues to expand as database participation and the available wealth of data in it continue to grow. This article reviews outcomes research and quality improvement articles published in 2015 based on STS CHSD data.

    We report the case of a 39-year-old male with complex cyanotic congenital heart disease undergoing emergency craniotomy for a cerebral abscess. Maintenance of intraoperative hemodynamic stability and adequate tissue oxygenation during anesthesia may be challenging in patients with cyanotic congenital heart disease. In this case, we decided to perform the surgery as an awake craniotomy after interdisciplinary consensus. We discuss general aspects of anesthetic management during awake craniotomy and specific concerns in the perioperative care of patients with congenital heart disease. PMID:27928498

    The diagnosis and treatment for paediatric and congenital cardiac disease has undergone remarkable progress over the last 60 years. Unfortunately, this progress has been largely limited to the developed world. Yet every year approximately 90% of the more than 1,000,000 children who are born with congenital cardiac disease across the world receive either suboptimal care or are totally denied care.While in the developed world the focus has changed from an effort to decrease post-operative mortality to now improving quality of life and decreasing morbidity, which is the focus of this Supplement, the rest of the world still needs to develop basic access to congenital cardiac care. The World Society for Pediatric and Congenital Heart Surgery [http://www.wspchs.org/] was established in 2006. The Vision of the World Society is that every child born anywhere in the world with a congenital heart defect should have access to appropriate medical and surgical care. The Mission of the World Society is to promote the highest quality comprehensive care to all patients with pediatric and/or congenital heart disease, from the fetus to the adult, regardless of the patient's economic means, with emphasis on excellence in education, research and community service.We present in this article an overview of the epidemiology of congenital cardiac disease, the current and future challenges to improve care in the developed and developing world, the impact of the globalization of cardiac surgery, and the role that the World Society should play. The World Society for Pediatric and Congenital Heart Surgery is in a unique position to influence and truly improve the global care of children and adults with congenital cardiac disease throughout the world [http://www.wspchs.org/].

    Anatomic delineation of the heart and great vessels is a necessity when managing children with congenital heart disease. Spatial orientation of the vessels and chambers in the heart and the heart itself may be quite abnormal. Though magnetic resonance imaging provides a noninvasive means for determining the anatomy, the intricate interrelationships between many structures are difficult to conceptualize from a 2-D format. Taking the 2-D images and using a volumetric analysis package allows for a 3-D replica of the heart to be created. This model can then be used to view the anatomy and spatial arrangement of the cardiac structures. This information may be utilized by the physicians to assist in the clinical management of these children.

    Our objective was to evaluate the usefulness of embolizing collateral vessels using mechanically detachable coils (MDCs) in children aged 3 years or younger with congenital heart disease. The subjects were 8 children with congenital heart disease featuring collateral vessels (age 18 days-3 years): 3 with a single ventricle, 2 with the tetralogy of Fallot, 2 with pulmonary atresia, and 1 with a ventricular septal defect. The embolized vessels were the major aortopulmonary collateral artery (MAPCA) in 5 patients, the persistent left superior vena cava in 2, and the coronary arteriovenous fistula in 1. A 4 or a 5 F catheter was used as the guiding device, and embolization was performed using MDCs and other conventional coils introduced through the microcatheter. One patient had growth of new MAPCAs after embolization, and these MAPCAs were also embolized with MDCs. Thus, a total of 9 embolization procedures were performed in 8 patients. Complete occlusion of the collateral vessels was achieved in 8 of 9 procedures (89%). Seven of 8 patients (88%) had uneventful courses after embolization, and MDC procedures appeared to play important roles in avoiding coil migration and achievement of safe coil embolization. One patient who underwent MAPCA embolization showed no improvement in heart function and died 2 months and 19 days later. Embolization of collateral vessels using MDCs in young children with congenital heart disease can be an effective procedure and a valuable adjunct to surgical management.

    CITED2 was identified as a cardiac transcription factor which is essential to the heart development. Cited2-deficient mice showed cardiac malformations, adrenal agenesis and neural crest defects. To explore the potential impact of mutations in CITED2 on congenital heart disease (CHD) in humans, we screened the coding region of CITED2 in a total of 700 Chinese people with congenital heart disease and 250 healthy individuals as controls. We found five potential disease-causing mutations, p.P140S, p.S183L, p.S196G, p.Ser161delAGC and p. Ser192_Gly193delAGCGGC. Two mammalian two-hybrid assays showed that the last four mutations significantly affected the interaction between p300CH1 and CITED2 or HIF1A. Further studies showed that four CITED2 mutations recovered the promoter activity of VEGF by decreasing its competitiveness with HIF1A for binding to p300CH1 and three mutations decreased the consociation of TFAP2C and CITED2 in the transactivation of PITX2C. Both VEGF and PITX2C play very important roles in cardiac development. In conclusion, we demonstrated that CITED2 has a potential causative impact on congenital heart disease. PMID:24848765

    Causes of pulmonary arterial hypertension (PAH) are similar in adults and children. The main difference is that PAH secondary to congenital heart diseases, is the predominant cause in pediatric patients. Persistent pulmonary hypertension of the newborn shows completely different clinical course and pathophysiological mechanisms. It is usually seen in full term babies with a high morbidity and mortality rate. Improved prognosis has been reported with inhaled nitric oxide (NO) and extracorporeal membrane oxygenation therapy in babies hospitalized in well equipped and experienced newborn centers. Primary pulmonary hypertension and familial pulmonary hypertension are rare in pediatric age group because the diagnosis is initially made in adolescence. The incidence of PAH secondary to congenital heart disease is estimated as 1.6 - 12.5 case/million/year. Eisenmenger syndrome is diagnosed in 1% of patients with PAH. Patients with left to right shunts are the main group who develop pulmonary vascular disease if not treated in the early infancy. Some cyanotic congenital heart diseases are also the causes of PAH. The best treatment of patients at risk for the development of pulmonary vascular disease is prevention by early surgical elimination of defects or repairing the anatomy. Treatment options with vasodilating agents like NO, prostaglandin analogs, phosphodiesterase -5 inhibitors and endothelin receptor antagonists are used to improve survival and quality of life. Heart lung or bilateral lung transplantation is the only surgical option for many of these patients. Results of national and international registries will bring valuable epidemiological and prognostic perspectives to pediatric PAH.

    The question posed in the title of this article is: "Congenital Heart Surgery Databases Around the World: Do We Need a Global Database?" The answer to this question is "Yes and No"! Yes--we need to create a global database to track the outcomes of patients with pediatric and congenital heart disease. No--we do not need to create a new "global database." Instead, we need to create a platform that allows for the linkage of currently existing continental subspecialty databases (and continental subspecialty databases that might be created in the future) that will allow for the seamless sharing of multi-institutional longitudinal data across temporal, geographical, and subspecialty boundaries. This review article will achieve the following objectives: (A) Consider the current state of analysis of outcomes of treatments for patients with congenitally malformed hearts. (B) Present some principles that might make it possible to achieve life-long longitudinal monitoring and follow-up. (C) Describe the rationale for the creation of a Global Federated Multispecialty Congenital Heart Disease Database. (D) Propose a methodology for the creation of a Global Federated Multispecialty Congenital Heart Disease Database that is based on linking together currently existing databases without creating a new database. To perform meaningful multi-institutional analyses, any database must incorporate the following six essential elements: (1) Use of a common language and nomenclature. (2) Use of a database with an established uniform core dataset for collection of information. (3) Incorporation of a mechanism to evaluate the complexity of cases. (4) Implementation of a mechanism to assure and verify the completeness and accuracy of the data collected. (5) Collaboration between medical and surgical subspecialties. (6) Standardization of protocols for life-long longitudinal follow-up. Analysis of outcomes must move beyond recording 30-day or hospital mortality, and encompass longer

    To test the effect of maternal habits and home exposures during early pregnancy on the occurrence of congenital heart disease in the offspring, 406 cases and 756 controls were studied. The cases included all cardiovascular malformations detected in Finland during 1982-1983, while the healthy controls were randomly selected from all babies born during the same period. Case and control mothers were interviewed after delivery using a structured and pre-tested questionnaire. Maternal overall drug consumption during the first trimester was as prevalent among case mothers (13.3%) as controls (14.6%). Neither was the risk of congenital heart disease associated with maternal use of contraceptive pills, salicylates, diazepam, or sweetening agents separately. Maternal exposures to disinfectants, dyes, lacquers, paints, pesticides, or glues at home were equally prevalent in case and control groups. Several earlier miscarriages was a predictor of an infant born with congenital heart disease (OR = 2.7, CI95 = 1.4-5.3). Maternal ultrasound examination was performed during the first 16 weeks of pregnancy more often among the case group (28.3%) than among the control group (22.0%). However, the association between ultrasound examination and the risk of congenital heart disease in the offspring was not statistically significant (OR = 1.2, 95% confidence interval 0.9-1.7) when adjusted for confounding factors such as the threat of miscarriage in logistic regression analysis. It is concluded that maternal ultrasound examination, intake of some common drugs, and exposure to a number of environmental factors at home during early pregnancy are probably not harmful for the developing fetal heart.

    Background: Congenital heart defects may be environmentally related, but the association with elevated ambient temperature has received little attention. Objectives: We studied the relationship between outdoor heat during the first trimester of pregnancy and risk of congenital heart defects. Methods: We carried out a retrospective cohort study of 704,209 fetuses between 2 and 8 weeks postconception from April to September in Quebec, Canada, 1988–2012. We calculated the prevalence of congenital heart defects at birth according to the number of days women were exposed to maximum temperature ≥ 30°C. In log-binomial regression models, we estimated prevalence ratios (PR) and 95% confidence intervals (CI) for the relationship of temperature with seven critical and eight noncritical heart defects, adjusted for pregnancy characteristics. Results: Prevalence of congenital heart defects was 979.5 per 100,000 for 10 days or more of temperature ≥ 30°C compared with 878.9 per 100,000 for 0 days of exposure. Temperature was more precisely associated with noncritical than critical defects, which had lower prevalence. Fetuses exposed to 15 days of temperature ≥ 30°C between 2 and 8 weeks postconception had 1.06 times the risk of critical defects (95% CI: 0.67, 1.67) and 1.12 times the risk of noncritical defects (95% CI: 0.98, 1.29) relative to 0 days. Associations were higher for atrial septal defects (PR 1.37, 95% CI: 1.10, 1.70) than for other noncritical defects. For atrial septal defects, associations with elevated temperatures began the 3rd week postconception. Conclusions: Extreme heat exposure during the first trimester may be associated with noncritical heart defects, especially of the atrial septum.

    The prevalence of heart failure in patients with congenital heart disease, mainly due to large left to right shunts, is as high as 20%. Heart failure has a high impact on prognosis, growth and neurodevelopment. Prior to surgery or after palliative procedures children need a medical heart failure therapy. The traditional therapy with digoxin, diuretics and ACE-inhibitors is not supported by prospective randomized trials. Propranolol had a significant beneficial effect on the clinical heart failure score, neurohormonal activation, heart rate variability and cardiac remodeling in the prospective randomized trial CHF-Pro-Infant. Beta-blocker dosages depend on heart rate with a target between 100 and 110 bpm in infants and an average dose of 2mg/kg/day after a titration period of 2 to 3 weeks. Within the last 18 years after the first case the author treated only infants with severe heart failure and highly elevated Pro-BNP-levels (8879 pg/ml on average). However we never observed serious side effects due to worsening heart failure, severe bradycardia or pulmonary obstruction. Diuretics are given as low as necessary to prevent the activation of the renin-angiotensin-aldosterone system with its detrimental effect on cardiac remodeling.

    The purpose of this study was to evaluate the correlation between anthropometric measures of children with congenital heart disease with percentiles that represent their growth indicators. Anthropometric evaluations of 135 hospitalized children with congenital heart disease were performed in a hospital specialized in cardiac diseases in Fortaleza, CE, Brazil. For the growth evaluation, percentiles of height by age, weight by height and weight by age were calculated. Children's average age was 4.74 months (+ 3.78) and 66.7% of the children were male. The medians of the three percentiles presented values below percentile 10, indicating a high proportion of values considered of risk. The subscapular thickness presented positive correlation with the three percentiles. The values of percentiles studied indicated growth delay.

    Abstract Objective  To determine the health‐related experiences of children with congenital heart disease. Design  Qualitative, semi‐structured interviews. Participants  A purposive sample (N = 35) of children and young people, aged between 8 and 19 years, with a variety of congenital heart conditions recruited from one treatment care centre in the north of England. Results  The main themes identified included: physical limitations of their condition; restrictions; attitudes of others; choices about information; coping with life and privacy. Conclusions  This study suggests that while many of this sample of children said that they coped well with their condition some children did experience significant impact on their quality of life in several domains. Children and young people identified a need for improved strategies to help them communicate about their condition with peers, schoolteachers and health‐care professionals to allow a better understanding of what they are able to achieve.

    In 2011, statewide newborn screening programs for critical congenital heart defects began in the United States, and subsequently screening has been implemented widely. In this review, we focus on data reports and collection efforts related to both prenatal diagnosis and newborn screening. Defect-specific, maternal, and geographic factors are associated with variations in prenatal detection, so newborn screening provides a population-wide safety net for early diagnosis. A new web-based repository is collecting information on newborn screening program policies, quality indicators related to screening programs, and specific case-level data on infants with these defects. Birth defects surveillance programs also collect data about critical congenital heart defects, particularly related to diagnostic timing, mortality, and services. Individuals from state programs, federal agencies, and national organizations will be interested in these data to further refine algorithms for screening in normal newborn nurseries, neonatal intensive care settings, and other special populations; and ultimately to evaluate the impact of screening on outcomes.

    Congenital heart disease (CHD) patients have increased prevalence of extra-cardiac congenital anomalies (CA) and risk of neurodevelopmental disabilities (NDD). Exome sequencing of 1,213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD and CA but only 2% with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, an mRNA splice regulator. Genes mutated in other cohorts ascertained for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients. PMID:26785492

    2016-01-01

    Advances in surgical repair techniques for various types of congenital heart disease have improved survival into adulthood over the past decades, thus exposing these patients to a high risk of atrial and ventricular arrhythmias later in life. These arrhythmias arise from complex arrhythmogenic substrates. Substrate formation may depend on both pathological myocardial remodelling and variable anatomical boundaries, determined by the type and timing of prior corrective surgery. Accordingly, arrhythmogenic substrates after repair have changed as a result of evolving surgical techniques. Radiofrequency catheter ablation offers an important therapeutic option but remains challenging due to the variable anatomy, surgically created obstacles and the complex arrhythmogenic substrates. Recent technical developments including electroanatomical mapping and image integration for delineating the anatomy facilitate complex catheter ablation procedures. The purpose of this review is to provide an update on the changing anatomical arrhythmogenic substrates and their potential impact on catheter ablation in patients with repaired congenital heart disease and tachyarrhythmias.

    The BREATHE-5 study demonstrated that bosentan, an oral endothelin receptor antagonist, provides clinical benefits in patients with Eisenmenger's syndrome. As a result, the European Medicines Agency (EMEA) approved its use for this indication. However, follow-up in that study was limited to 16 weeks and patients with complex congenital heart disease were excluded. We assessed the effect of long-term bosentan treatment in 10 patients with complex congenital heart disease and Eisenmenger's syndrome. In the mean clinical follow-up period of 25 months, all patients reached the target dose without developing side effects and without experiencing a change in arterial oxygen consumption at either rest or maximal exercise. Moreover, there were significant changes in clinical parameters: NYHA functional class improved from 3.3+/-0.7 to 2.5+/-0.9 (P=.002) and the 6-minute walk distance increased from 266+/-161 m to 347+/-133 m (P=.015).

    OBJECTIVE--To assess the prevalence and patterns of congenital heart defects in infants requiring hospital admission in a defined population and to determine the differences in ethnic groups. DESIGN--A three year retrospective analysis of all hospital admissions for paediatric congenital heart defects in a single centre. SETTING--Tertiary referral centre for infant cardiac services in the West Midlands region, United Kingdom. PATIENTS AND METHODS--Indian, Pakistani, Bangladeshi and other individuals from the Indian subcontinent constitute 5.8% of the total population of the West Midlands region. Some 9% of infants, however, are Asian because of a high birth rate. All infants with confirmed congenital heart defects resident in this region who required hospital admission between April 1990 and March 1993 were classified as Asians and non-Asian, mainly white, infants. RESULTS--Of 1111 infants with congenital heart defects born in the West Midlands and admitted to the hospital, 17.0% were Asian, significantly more than the percentage of Asian infants in the population (P < 0.0001). Asian infants had a higher proportion of complex congenital heart disease (7% v 2.1%, P < 0.001), whereas coarctation of the aorta was more common in non-Asian (3% v 9.1%, P = 0.003). Persistent arterial duct seemed to be more common in Asian children (16% v 10%, NS), but this group included preterm infants admitted for duct ligation. There was no significant difference between the two groups in the other nine categories of congenital heart defects. CONCLUSIONS--The estimated prevalence of congenital heart defects requiring hospital admission was higher in Asian infants than in non-Asian (9.45 per 1000 v 4.56 per 1000, P < 0.0001). Complex congenital heart defects were more common in Asian infants whereas coarctation of the aorta was more common in non-Asian. PMID:7696029

    Conotruncal cardiac defects are partially prevented by maternal folic acid supplementation. However, the biochemical mechanism is unknown. Maternal autoantibodies to folate receptors, previously associated with increased risk for neural tube defects, also may account for this effect. This study aimed to examine the titers of folate receptor-blocking autoantibodies in mothers of children with conotruncal congenital heart defects and to compare them with those in the general population. Serum samples were obtained from 22 women whose pregnancies were complicated by conotruncal congenital heart malformations. Groups of samples were analyzed for autoantibodies against [(3)H] folic acid-labeled folate receptors, quantitative amounts of immunoglobulin G (IgG) and IgM autoantibodies to the folate receptor, and for ability to block-bind folic acid to receptors. No elevated levels of antibodies binding to [(3)H] folic acid-labeled folate receptors were found. No difference was found in antifolate receptor alpha-IgG or IgM median levels between cases (261 vs. 240 μg/mL) and control subjects (773 vs. 924 μg/mL). There was no increased blocking of folic acid binding between cases [0.69 ng/mL; 95 % confidence interval (CI), 0.006-0.01] and control subjects (0.69 ng/mL; 95 % CI, 0.003-0.013). Although epidemiologic evidence suggests that periconceptual folic acid may prevent many conotruncal congenital heart defects, the current study suggests that this effect is unlikely to be explained by the presence of maternal autoantibodies to folate receptor. These data suggest that a strategy of screening women for such autoantibodies will not identify a high-risk group of women to target for supplemental folic acid to prevent congenital heart defects.

    Objective To evaluate the family psychosocial outcomes of children with Down syndrome and atrioventricular septal defect, and examine the impact of these variables on the child’s neurodevelopmental outcome. Methods This was a cross-sectional study that consisted of 57 children with Down syndrome (20 cases and 37 controls), approximately 12–14 months of age. In both groups, we assessed the development of the child, the quality of the child’s home environment, and parenting stress. Results Compared with the Down syndrome without congenital heart defect group, the atrioventricular septal defect group revealed lower scores in all developmental domains, less optimal home environments, and higher parental stress. Significant differences in development were seen in the areas of cognition (p=0.04), expressive language (p=0.05), and gross motor (p<0.01). The Home Observation for Measurement of the Environment revealed significant differences in emotional and verbal responsiveness of the mother between the two groups. The Parenting Stress Index revealed the Down syndrome with atrioventricular septal defect group had a significantly higher child demandingness subdomain scores compared to the Down syndrome without congenital heart defect group. Conclusions The diagnosis of a congenital heart defect in addition to the diagnosis of Down syndrome may provide additional stress to the child and parents, elevating parental concern and disrupting family dynamics, resulting in further neurodevelopmental deficits. Finding that parental stress and home environment may play a role in the neurodevelopmental outcomes may prompt new family-directed interventions and anticipatory guidance for the families of children with Down syndrome who have a congenital heart defect.

    Digital subtraction angiography (DSA) of the heart was performed in 54 patients for the evaluation of congenital heart diagnostic images and accurate physiologic shunt data that compared favorably with catheter angiography and nuclear medicine studies. Retrospective analysis of this series of patients indicated that DSA studies contributed sufficient informantion to shorten significantly or modify cardiac catheterization in 85% (79/93) of the defects that were identified. Interatrial septal defects were particularly well diagnosed, with identification occurring in 10 of 10 cases, wheseas intraventricular septal defects were identified in only 6 of 9 patients. Evaluation of postsurgical patients was accurate in 19 of 20 cases.

    The majority of congenital heart defects occur without identifiable risk factors. Detection rates are therefore highly dependent on the experience and expertise of the obstetrical screening operator. In the first trimester, the risk of congenital heart defects increases with increasing nuchal thickness (≥2.5 mm detects 44% of major congenital heart defects), but because of the number of false positives, the positive predictive value is only a few percent. The anatomy of major congenital heart defects may be delineated in less than half of the fetuses during early second trimester. The reported yield of congenital heart defects detection during the mid-gestational routine obstetrical screening has improved over time and detection rates up to 85% of major congenital heart defects have been reported when outflow tract and three-vessel views are included in conjunction with the four-chamber view. Improved detection rates have been achieved following screening operator training interventions combined with a low referral threshold to obtain a detailed fetal echocardiographic study.

    Maternal age is a risk factor for congenital heart disease even in the absence of any chromosomal abnormality in the newborn. Whether the basis of this risk resides with the mother or oocyte is unknown. The impact of maternal age on congenital heart disease can be modelled in mouse pups that harbour a mutation of the cardiac transcription factor gene Nkx2-5 (ref. 8). Here, reciprocal ovarian transplants between young and old mothers establish a maternal basis for the age-associated risk in mice. A high-fat diet does not accelerate the effect of maternal ageing, so hyperglycaemia and obesity do not simply explain the mechanism. The age-associated risk varies with the mother's strain background, making it a quantitative genetic trait. Most remarkably, voluntary exercise, whether begun by mothers at a young age or later in life, can mitigate the risk when they are older. Thus, even when the offspring carry a causal mutation, an intervention aimed at the mother can meaningfully reduce their risk of congenital heart disease.

    Adult congenital heart disease, previously considered a rare comorbidity, is increasingly becoming a reality for today's anesthesia providers. Improvements in prenatal diagnosis, sophisticated surgical techniques and equipment, advances in pediatric critical care, enhanced efficacy of cardiovascular pharmacologic agents, and an overall increase in postrepair survival rates have resulted in an estimated population of approximately 800,000 adults with congenital heart disease. Despite successful surgical repair or palliation, these individuals present the anesthesia provider with a multitude of challenges. Individualized care of these fragile patients should be approached with a keen understanding of the patient's underlying cardiac anomaly. This case report chronicles the anesthetic care of a 36-year-old woman presenting for left-sided ureteroscopy with laser lithotripsy and stent placement. Her medical history was remarkable for the presence of complex congenital heart disease consisting of multiple anomalies: a double-outlet right ventricle, transposition of the great arteries, pulmonary stenosis, atrial septal defect, and a hypoplastic left ventricle with concomitant mitral valve atresia. General anesthesia was successfully administered, with meticulous attention given to maintenance of systemic vascular resistance to minimize shunting, oxygenation, administration of preprocedure antibiotics, and judicious replacement of intravenous fluids via air-filtered tubing.

    Postoperative impairment of right ventricular (RV) systolic function can appear after surgical repair of complex congenital heart defects, such as tetralogy of Fallot; it is caused by chronic volume and/or pressure overload due to pulmonary regurgitation and/or stenosis. RV dysfunction is strongly associated with prognosis in these patients. Cardiac magnetic resonance imaging is the gold standard for quantification of RV volumes and ejection fraction in patients with congenital heart diseases; however, it is costly and is not widely available. Echocardiography is the imaging modality that is most available and most frequently used to assess RV systolic function. However, RV ejection fraction cannot be measured accurately by standard two-dimensional echocardiography because of its pyramidal shape. Surrogate parameters of RV systolic function are mostly used in routine practice. New techniques of two-dimensional strain and three-dimensional quantification of RV volumes and ejection fraction have been developed in recent years. The aim of this article is to show the pertinence of each variable of RV systolic function measured by echocardiography in patients with repaired congenital heart disease and residual chronic RV overload.

    Abstract Objective To explore the need for information and what information was actually received following prenatal diagnosis of a congenital heart defect, in a country where termination of pregnancy beyond 22 weeks of gestation is not easily possible because of legal constraints. Methods Twenty‐six Swedish‐speaking pregnant women (n = 14) and partners (n = 12) were consecutively recruited for semi‐structured telephone interviews following the prenatal diagnosis of a congenital heart defect. Data were analyzed using content analysis. Results Although high satisfaction with the specialist information was described, the information was considered overwhelming and complex. Objective, honest, and detailed information about multiple subjects were needed, delivered repeatedly, and supplemented by written information/illustrations. Eighteen respondents had used the Internet to search for information and identified issues involving searching difficulties, low quality, and that it was too complex, insufficient, or unspecific. Those who terminated their pregnancy criticized that there was a lack of information about termination of pregnancy, both from health professionals and online sources, resulting in unanswered questions and unpreparedness. Conclusion Individuals faced with a prenatal diagnosis of a congenital heart defect need individualized and repeated information. These needs are not all adequately met, as individuals are satisfied with the specialist consultation but left with unanswered questions regarding pregnancy termination. © 2016 The Authors.

    New generation multislice CT technology has changed the approach to non‐invasive assessment of congenital heart disease, in both paediatric and adult patients. This is mainly because of rapid advances in spatial and temporal resolution and in post‐processing capability. At Hôpital Necker‐Enfants Malades, CT with multiplanar and three‐dimensional reconstruction has become a routine examination in the evaluation of congenital heart disease planning surgery, complex interventional catheterisations and for follow‐up. It has proved to be an invaluable diagnostic and decision‐aiding methodology in these situations, as a complement to echocardiography and, increasingly, as a substitute for diagnostic angiography (which is usually associated with higher‐dose radiation and longer sedation times, as well as occasional morbidity). This review illustrates the current status of 64‐slice CT in congenital heart diseases, including assessment of the aorta, the coronary arteries, the pulmonary arteries, the systemic and pulmonary veins, and other intra‐ and extracardiac malformations.

    Purpose To ascertain the primary caregiver’s post discharge perceptions of infant care issues after neonatal heart surgery. Study Design & Methods Fifteen primary caregivers of infants who had neonatal heart surgery for complex CHD participated in this study. We conducted two focus groups, and four individual phone interviews using a structured interview guide. The topics included: parent feeding management, infant caloric intake, parental acceptance of nasogastric tube, infant feeding behaviors and issues of parenting stress. We audio recorded focus group sessions, made detailed notes and key quotes were recorded verbatim by a certified impartial focus group facilitator. Results Feeding problems were present in both infants who were on full oral feeds as well as infants who were dependent on supplemental feeding tubes. Mothers of infants with feeding problems expressed concern over weight gain and sleep deprivation, which largely contributed to parental stress. Clinical Implications In this small study of infants who experienced neonatal surgery for complex CHD, parental stress over feeding and weight gain needed to be addressed during hospitalization. Future studies are needed to address increased at-home parental support. PMID:22357070

    The purpose of this study was to evaluate the effectiveness of combined surgical and medical treatment of infective endocarditis in patients with congenital valvular heart disease when included in a regimen of the drug Reamberin. In this regard, the analysis of the effectiveness of a combination regimen of 74 patients with valvular congenital heart diseases complicated with infective endocarditis. Given the indications for surgical correction operative technique features and possible technical difficulties in carrying out such operations, due to the inflammatory changes and tissue destruction, and ways to overcome them. For the correction of metabolic disorders in the postoperative period, 47 patients (main group) was appointed Reamberin: once, intravenous drip 400 ml/day during the first 5 days after surgery. 27 patients (control group) was conducted infusion therapy depending on the severity of the condition according to the classical scheme. In addition to standard clinical and laboratory examination, to assess the effectiveness of Reamberin was investigated catalase activity of CPK in blood serum in the dynamics of observation (1, 3 and 5 days after surgery). It is revealed that surgical approach, used in complex treatment of patients with valvular congenital heart diseases, including reorganization of the cavities of the heart, increasing the frequency of joints and the use of reinforcing strips of synthetic material that prevents the cutting of sutures through the inflamed tissue has achieved good short-and long-term results. Infective endocarditis and destruction of the valvular annulus fibrosus the use of a frame of strips of polytetrafluoroethylene allows you to restore its integrity and to implant a mechanical prosthesis. The inclusion in the regimen of patients with infective endocarditis complicated by cardiac insufficiency in the early postoperative period the drug Reamberin improves the efficiency of treatment by a more rapid restoration of the normal

    Purpose The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) is the largest Registry in the world of patients who have undergone congenital and pediatric cardiac surgical operations. The Congenital Heart Surgeons’ Society Database (CHSS-D) is an Academic Database designed for specialized detailed analyses of specific congenital cardiac malformations and related treatment strategies. The goal of this project was to create a link between the STS-CHSD and the CHSS-D in order to facilitate studies not possible using either individual database alone and to help identify patients who are potentially eligible for enrollment in CHSS studies. Methods Centers were classified on the basis of participation in the STS-CHSD, the CHSS-D, or both. Five matrices, based on CHSS inclusionary criteria and STS-CHSD codes, were created to facilitate the automated identification of patients in the STS-CHSD who meet eligibility criteria for the five active CHSS studies. The matrices were evaluated with a manual adjudication process and were iteratively refined. The sensitivity and specificity of the original matrices and the refined matrices were assessed. Results In January 2012, a total of 100 centers participated in the STS-CHSD and 74 centers participated in the CHSS. A total of 70 centers participate in both and 40 of these 70 agreed to participate in this linkage project. The manual adjudication process and the refinement of the matrices resulted in an increase in the sensitivity of the matrices from 93% to 100% and an increase in the specificity of the matrices from 94% to 98%. Conclusion Matrices were created to facilitate the automated identification of patients potentially eligible for the five active CHSS studies using the STS-CHSD. These matrices have a sensitivity of 100% and a specificity of 98%. In addition to facilitating identification of patients potentially eligible for enrollment in CHSS studies, these matrices will allow (1) estimation of

    It is the myocardium that bears the basic functional loading during heart working, including muscle contractility and enzyme activity. The elemental concentrations in myocardium tissue of heart were determined by SRXRF technique. Our investigation is systematical: the elemental content in each compartment (left and right ventricles, left and right auricles) of hearts of healthy and diseased children (congenital heart diseases, transposition of main vessels (TMV)) was analyzed. The elemental distribution in myocardium of four heart chambers of human fetuses was also analyzed. Following elements were determined: S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Rb, Sr. It was revealed that the elemental concentrations in myocardium of both ventricles are almost constant in heart of fetuses and healthy children. The transition from pre-natal study (fetus) to post-natal study is accompanied by the redistribution of chemical elements in myocardium. The higher concentrations of S, Fe, Ca, Sr and Cu in myocardium of children are observed, the content of K, Br, Rb and especially Se is lower than in heart of fetuses. The elemental distribution in myocardium of children TMV is considerably different in comparison with the healthy children: the higher levels of Cu are observed. The content of Se is lower.

    Cardiac malformations are the most common birth defect. Better interventions in early life have improved mortality for children with congenital heart disease, but heart failure is a significant problem in adulthood. These patients require regular imaging and analysis of biventricular (left and right ventricular) function. In this study, we describe a rapid method to analyse left and right ventricular shape and function from cardiac MRI examinations. A 4D (3D+time) finite element model template is interactively customized to the anatomy and motion of the biventricular unit. The method was validated in 17 patients and 10 ex-vivo hearts. Interactive model updates were achieved through preconditioned conjugate gradient optimization on a multithread system, and by precomputing points predicted from a coarse mesh optimization.

    The use of mechanical circulatory support (MCS) devices is a viable therapeutic treatment option for patients with congestive heart failure. Ventricular assist devices, cavopulmonary assist devices, and total artificial heart pumps continue to gain acceptance as viable treatment strategies for both adults and pediatric patients as bridge-to-transplant, bridge-to-recovery, and longer-term circulatory support alternatives. We present a review of the current and future MCS devices for patients having congenital heart disease (CHD) with biventricular or univentricular circulations. Several devices that are specifically designed for patients with complex CHD are in the development pipeline undergoing rigorous animal testing as readiness experiments in preparation for future clinical trials. These advances in the development of new blood pumps for patients with CHD will address a significant unmet clinical need, as well as generally improve innovation of the current state of the art in MCS technology.

    Introduction Cardiac transplantation remains the gold standard for end-stage cardiomyopathies and congenital heart defects in pediatric patients. Objective This study aims to report on 20 years of experience since the first case and evaluate our results. Methods We conducted a retrospective analysis of the database and outpatient follow-up. Between October 1992 and April 2012, 109 patients underwent 114 transplants. 51.8% of them being female. The age of patients ranged from 12 days to 21 years with a mean of 8.8±5.7 years and a median of 5.2 years. The underlying diagnosis was dilated cardiomyopathy in 61.5%, congenital heart disease in 26.6% and restrictive cardiomyopathy in 11.9%. All patients above 17 years old had congenital heart disease. Results Survival rate at 30 days, 1, 5, 10, 15, and 20 years were 90.4%, 81.3%, 70.9%, 60.5%, 44.4% and 26.7%, respectively. Mean cold ischemic time was 187.9 minutes and it did not correlate with mortality (P>0.05). Infectious complications and rejection episodes were the most common complications (P<0.0001), occurring, respectively, in 66% and 57.4% of the survivors after 10 years. There was no incidence of graft vascular disease and lymphoproliferative disease at year one, but they affected, respectively, 7.4% and 11% of patients within 10 years. Conclusion Twenty-year pediatric heart transplant results at our institution were quite satisfactory and complication rates were acceptable. PMID:25372904

    The aim of this study was to estimate the incidence and to analyze the anatomy of double inlet-double outlet right ventricle complex and its associated cardiac anomalies in our autopsy series. Among the 1640 hearts with congenital heart disease of our Anatomical Collection, we reviewed the specimens with double inlet-double outlet right ventricle, according to the sequential-segmental analysis, identifying associated cardiac anomalies and examining lung histology to assess the presence of pulmonary vascular disease. We identified 14 hearts with double inlet-double outlet right ventricle (0.85%). Right atrial isomerism was observed in 10 hearts, situs solitus in 3 and left atrial isomerism in one. Regarding the mode of atrioventricular connection, all hearts but one had a common atrioventricular valve. Systemic or pulmonary venous abnormalities were noted in all patients with atrial isomerism. In nine patients a valvular or subvalvular pulmonary stenosis was present. Among the functionally "univentricular hearts", double inlet- double outlet right ventricle represents a peculiar entity, mostly in association with right atrial isomerism. Multiple cardiac anomalies are associated and may complicate surgical repair.

    Advances in cardiac surgical techniques and perioperative intensive care have led to improved survival in babies with congenital heart disease (CHD). While it is true that the majority of children with CHD today will survive, many will have impaired neurodevelopmental outcome across a wide spectrum of domains. While continuing to improve short-term morbidity and mortality is an important goal, recent and ongoing research has focused on defining the impact of CHD on brain development, minimizing postnatal brain injury, and improving long-term outcomes. This paper will review the impact that CHD has on the developing brain of the fetus and infant. Neurologic abnormalities detectable prior to surgery will be described. Potential etiologies of these findings will be discussed, including altered fetal intrauterine growth, cerebral blood flow and brain development, associated congenital brain abnormalities, and risk for postnatal brain injury. Finally, reported neurodevelopmental outcomes after surgical repair of CHD will be reviewed.

    Congenital heart disease (CHD) is the most common form of congenital abnormality and occurs in over 1% of newborns. Approximately 30% of children with CHD have other extra-cardiac anomalies, which significantly increases mortality in CHD patients. It is expected that the number of CHD patients who consult non-specialized hospitals for non-cardiac surgery after palliative or corrective operations will increase because of the extraordinary progression of treatments, such as surgical procedures, interventional procedures, and intensive care medicine, as well as diagnosis. The aim of this article is to enable anaesthesiologists who are not usually engaged in the anaesthesia management of CHD patients to provide perioperative management for CHD patients safely and with confidence by having basic and advanced knowledge about CHD patients and their pathophysiological characteristics.

    Despite the recent advances in computational modeling, experimental simulation of the circulation with congenital heart defect using mock flow circuits remains an important tool for device testing, and for detailing the probable flow consequences resulting from surgical and interventional corrections. Validated mock circuits can be applied to qualify the results from novel computational models. New mathematical tools, coupled with advanced clinical imaging methods, allow for improved assessment of experimental circuit performance relative to human function, as well as the potential for patient-specific adaptation. In this review, we address the development of three in vitro mock circuits specific for studies of congenital heart defects. Performance of an in vitro right heart circulation circuit through a series of verification and validation exercises is described, including correlations with animal studies, and quantifying the effects of circuit inertiance on test results. We present our experience in the design of mock circuits suitable for investigations of the characteristics of the Fontan circulation. We use one such mock circuit to evaluate the accuracy of Doppler predictions in the presence of aortic coarctation. PMID:21218147

    Sports camps for children with cardiac anomalies have existed for many years. However, no formal evaluation of the benefits of attending such camps has been undertaken heretofore. We assessed potential changes in the self-perceived health of children with congenital heart disease who attended a special sports camp. Thirty-one children with cardiac anomalies attended a 3-day multisports camp. Sixteen children, all of whom were 10 years or older, literate, and Dutch- or French-speaking, completed the Child Health Questionnaire (CHQ-CF87) before and after attending the camp. The scores of the children were compared with those of healthy peers by calculating mean standardized differences. After attendance at the sports camp, the children achieved significant improvements in the self-perception of their physical functioning, role functioning due to emotional problems, role functioning due to behavioral problems, mental health, and general behavior. The children's self-esteem and general behavior after the camp were significantly better than that of their healthy counterparts. We conclude that children with congenital heart disease who participate in activities at special sports camps may reap benefits in terms of their subjective health status. Although further research is needed, we recommend the participation in sport activities by children with heart defects, and more specifically their participation in sports camps.

    Congenital heart defects (CHD) are the leading cause of infant mortality among birth defects, and later morbidities and premature mortality remain problematic. Although genetic factors contribute significantly to cause CHD, specific genetic lesions are unknown for most patients. The National Heart, Lung, and Blood Institute-funded Pediatric Cardiac Genomics Consortium established the Congenital Heart Disease Genetic Network Study to investigate relationships between genetic factors, clinical features, and outcomes in CHD. The Pediatric Cardiac Genomics Consortium comprises 6 main and 4 satellite sites at which subjects are recruited, and medical data and biospecimens (blood, saliva, cardiovascular tissue) are collected. Core infrastructure includes an administrative/data-coordinating center, biorepository, data hub, and core laboratories (genotyping, whole-exome sequencing, candidate gene evaluation, and variant confirmation). Eligibility includes all forms of CHD. Annual follow-up is obtained for probands <1-year-old. Parents are enrolled whenever available. Enrollment from December 2010 to June 2012 comprised 3772 probands. One or both parents were enrolled for 72% of probands. Proband median age is 5.5 years. The one third enrolled at age <1 year are contacted annually for follow-up information. The distribution of CHD favors more complex lesions. Approximately, 11% of probands have a genetic diagnosis. Adequate DNA is available from 97% and 91% of blood and saliva samples, respectively. Genomic analyses of probands with heterotaxy, atrial septal defects, conotruncal, and left ventricular outflow tract obstructive lesions are underway. The scientific community's use of Pediatric Cardiac Genomics Consortium resources is welcome.

    Health care is embarking on a new era of increased transparency. In January 2015, the Society of Thoracic Surgeons (STS) began to publicly report outcomes of pediatric and congenital cardiac surgery using the 2014 Society of Thoracic Surgeons Congenital Heart Surgery Database (STS CHSD) Mortality Risk Model. Because the 2014 STS CHSD Mortality Risk Model adjusts for procedural factors and patient-level factors, it is critical that centers are aware of the important impact of incomplete entry of data in the fields for patient-level factors. These factors are used to estimate expected mortality, and incomplete coding of these factors can lead to inaccurate assessment of case mix and estimation of expected mortality. In order to assure an accurate assessment of case mix and estimate of expected mortality, it is critical to assure accurate completion of the fields for patient factors, including preoperative factors. It is crucial to document variables such as whether the patient was preoperatively ventilated or had an important noncardiac congenital anatomic abnormality. The lack of entry of these variables will lead to an underestimation of expected mortality. The art and science of assessing outcomes of pediatric and congenital cardiac surgery continues to evolve. In the future, when models have been developed that encompass other outcomes in addition to mortality, pediatric and congenital cardiac surgical performance may be able to be assessed using a multidomain composite metric that incorporates both mortality and morbidity, adjusting for the operation performed and for patient-specific factors. It is our expectation that in the future, this information will also be publicly reported. In this era of increased transparency, the complete and accurate coding of both patient-level factors and procedure-level factors is critical.

    This study compares the current, prenatal detection rate for critical congenital heart disease in Southern Nevada with the previously reported rate, after developing and expanding a comprehensive, community-wide fetal cardiology program. For the current-period analysis, we inquired our database and electronic health records for patients born in Clark County, Nevada, with critical congenital heart disease between May 2012 and April 2014, and we compared the results with the previous period between May 2003 and April 2006. The major components of the community-wide program include fetal congenital heart disease screening via general obstetric ultrasound studies performed in obstetrician's offices, radiology imaging centers, or maternal-fetal medicine specialty practices; subsequent referral for comprehensive fetal echocardiography performed in maternal-fetal medicine offices under the on-site supervision by fetal cardiologists; and recurring community educational programs teaching the 5-axial plane, fetal echocardiographic screening protocol to general obstetric sonographers and instructing perinatal sonographers in advanced imaging topics. For the current period, the prenatal detection rate for critical congenital heart disease in Southern Nevada was 71 versus 36% for the previous period (p < 0.001). The temporal improvement in prenatal detection of critical congenital heart disease may be related to our expanded decentralized, community-wide fetal cardiology program, and our experiences may be applicable to other metropolitan areas.

    Our previous study indicated that 8 patients from a family with a history of congenital heart disease had simple atrial septal defect (ASD) and carried the same mutation at codon 310 in the GATA4 gene. In the present study, to identify the functional defects caused by this mutation in an in vivo model, the transgene DNA constructs were microinjected into mice to generate a transgenic mouse model. The mice were genotyped using PCR and DNA sequencing. Protein expression was measured by western blot analysis. qPCR was used to determine the copy number of the transgenes. The heart tissue was fixed and sectioned by conventional procedures. The Vevo 2000 system was used to perform echocardiography on the mice. The expression of GATA4 target genes was measured using the real-time PCR system. The incidence of ASD in the heterozygous transgenic mice was found to be greater than that in the wild-type control mice (P<0.05). In addition, the expression of α-myosin heavy chain (α-MHC) in the heart tissues from the homozygous mice was lower than that in the heart tissues from their wild-type littermates (P<0.05). In conclusion, these results suggest that the introduction of GATA4 M310V negatively affects the normal expression of α-MHC. In accordance with previous findings on GATA4 mutation screening and in vitro experiments, this study confirms that GATA4 M310V mutation may lead to the development of the congenital heart defect, ASD.

    The demonstration of congenital heart disease at autopsy necessitates the careful preservation and examination of the heart, the vessels, and their connections. Techniques preserving these connections and using a reproducible and systematic approach are preferred. The Rokitansky method of organ block dissection, in combination with a system of heart examination termed sequential segmental analysis, provides such an approach. This study is based on the examination of heart specimens accessioned into the Frank E. Sherman, M.D., and Cora C. Lenox, M.D., Heart Museum (containing approximately 2400 specimens) of the Pathology Department, Children's Hospital of Pittsburgh. Specimens received in consultation during a 25-year period from hospitals and coroners'/medical examiners' offices were examined, and the corresponding reports were reviewed. Of 46 total heart specimens examined (1975-1999), 29 (63%) were dissected properly or left intact for dissection at Children's Hospital of Pittsburgh, and 17 (37%) were incorrectly dissected for the demonstration of congenital heart disease. Of these 17 cases, 11 (24%) displayed dissection errors, which did not hinder a complete diagnosis, 3 cases (6.5%) had errors that enabled only an incomplete diagnosis, and in 3 cases (6.5%), no diagnosis of congenital heart disease could be made. Dissection mistakes and means of avoiding them are discussed. Review of medical and family history, external and internal examination, and a reproducible and sequential method of examining the heart and its connections enables documentation of even the most complex cardiovascular anomalies.

    Fluid overload and prolonged mechanical ventilation lead to worse outcomes in critically ill children. However, the association between these variables in children following congenital heart surgery is unknown. The objectives of this study were to describe the association between fluid overload and duration of mechanical ventilation, oxygen requirement and radiologic findings of pulmonary and chest wall edema. This study is a retrospective chart review of patients who underwent congenital heart surgery between June 2010 and December 2013. Univariate and multivariate associations between maximum cumulative fluid balance and length of mechanical ventilation and OI were tested using the Spearman correlation test and multiple linear regression models, respectively. There were 85 eligible patients. Maximum cumulative fluid balance was associated with duration of mechanical ventilation (adjusted analysis beta coefficient = 0.53, CI 0.38-0.66, P < 0.001), length of stay in the pediatric intensive care unit (Spearman's correlation = 0.45, P < 0.001), and presence of chest wall edema and pleural effusions on chest radiograph (Mann-Whitney test, P = 0.003). Amount of red blood cells transfused and use of nitric oxide were independently associated with increased duration of mechanical ventilation (P = 0.012 and 0.014, respectively). Fluid overload is associated with prolonged duration of mechanical ventilation and PICU length of stay after congenital heart surgery. Fluid overload was also associated with physiological markers of respiratory restriction. A randomized controlled trial of a restrictive versus liberal fluid replacement strategy is necessary in this patient population, but in the meantime, accumulating observational evidence suggests that cautious use of fluid in the postoperative care may be warranted.

    Post-traumatic stress disorder (PTSD) is associated with adverse outcomes and increased mortality in cardiac patients. No studies have examined PTSD in the adult congenital heart disease (ACHD) population. The objectives of this study were to assess the prevalence of self-reported symptoms of PTSD in patients with ACHD and explore potential associated factors. Patients were enrolled from an outpatient ACHD clinic and completed several validated measures including the Impact of Event Scale-Revised, PTSD Checklist-Civilian Version, and the Hospital Anxiety and Depression Scale. Clinical data were abstracted through medical data review. A total of 134 participants (mean age 34.6 ± 10.6; 46% men) were enrolled. Of the 127 participants who completed the Impact of Event Scale-Revised, 14 (11%) met criteria for elevated PTSD symptoms specifically related to their congenital heart disease or treatment. Of the 134 patients who completed PTSD Checklist-Civilian Version, 27 (21%) met criteria for global PTSD symptoms. In univariate analyses, patients with congenital heart disease-specific PTSD had their most recent cardiac surgery at an earlier year (p = 0.008), were less likely to have attended college (p = 0.04), had higher rates of stroke or transient ischemic attack (p = 0.03), and reported greater depressive symptoms on the Hospital Anxiety and Depression Scale (7 vs 2, p <0.001). In multivariable analysis, the 2 factors most strongly associated with PTSD were depressive symptoms (p <0.001) and year of most recent cardiac surgery (p <0.03). In conclusion, PTSD is present in 11% to 21% of subjects seen at a tertiary referral center for ACHD. The high prevalence of PTSD in this complex group of patients has important implications for the medical and psychosocial management of this growing population.

    Our purpose was to evaluate the efficacy of level two ultrasound screening for the detection of congenital heart defects (CHD) in a low-risk population by using three standardized cuts. Within a period of four years a total of 6727 pregnant women of a low-risk population undertook several ultrasound examinations on the basis of screening for fetal malformations. All ultrasound examinations were performed by three experienced doctors. At every single scan three standardized cuts (apical and lateral four-chamber view, crossing over of the great arteries) were obtained in order to detect congenital heart defects. Of 87 CHDs (1.33 per cent of the examined women) 39 (43.8 per cent) were diagnosed prenatally. The detection rate was 10/48 (20.8 per cent) in the presence of VSD, ASD2 or combined ASD2 + VSD, the detection rate was 29/39 (74.3 per cent) in the presence of other forms of congenital heart disease. None of the 38 missed cases in the first group but three of the ten missed CHDs in the second group had emergency neonatological problems. Aneuploidy and/or other malformations existed in 22/87 cases of CHD. The obstetrical management was changed in nearly all cases after the diagnosis of a CHD. Twenty-two women opted for termination of pregnancy because of additional fetal malformations or chromosomal defects. Five women were transferred prenatally to a tertiary centre for neonatal cardiac surgery. Ten deliveries were performed in the presence of a neonatologist. Good detection rates for CHD can be achieved in a low-risk population on the basis of level two ultrasound screening by using the above mentioned three cuts and thus, the perinatal mortality and morbidity can be improved.

    Severe coagulation defects often develop in neonates undergoing cardiac surgery, both as a result of the surgical intervention, and as pre-existing defects in the hemostatic mechanisms. The following case report describes a newborn patient with complex congenital heart disease and respiratory failure whose pre-operative coagulopathy was aggressively managed prior to surgical correction. A 5-day-old, 2.5 kg child presented with interrupted aortic arch, ventricular septal defect, atrial septal defect, and patent ductus arteriosus. On admission, he was in respiratory arrest suffering from profound acidemia. In addition, the child was hypothermic (30.1 degrees C), septic (Streptococcus viridans), and coagulopathic (disseminated intravascular coagulation-DIC). The patient was immediately intubated and initial coagulation assessment revealed the following: prothrombin time (PT) 48.9 s (international normalized ratio (INR) 15.7), activated partial thromboplastin time (aPTT) >106 s, platelet count 30,000 mm(3), fibrinogen 15 mg dL(-1) and antithrombin III (AT-III) 10%. Before cardiac surgery could be performed, the patient's DIC was corrected with the administration of cryoprecipitate (15 ml), fresh frozen plasma (300 ml), and platelets (195 ml). In spite of the large transfusion of fresh frozen plasma, the AT-III activity, measured as a percentage, remained depressed at 33. Initial thromboelastographic (TEG) determination revealed an index of +2.02, and following 100 IU administration of an AT-III concentrate, declined to -2.32. Sequential TEG profiles were performed over several days, with the results used to guide both transfusion and medical therapy. The congenital heart defect correction was subsequently performed with satisfactory initial results, but the patient developed a fungal infection and expired on the 16th post-operative day. The present case describes techniques of coagulation management for a newborn with both a severe hemostatic defect and congenital

    Chylothorax is defined as the accumulation of lymphatic fluid or chyle in the pleural space. Chylothorax treatment is composed of conservative; pleural drainage, termination of enteral feeding, total parenteral nutrition and supplementation with medium- chain triglycerides and surgical therapies; ductus thoracicus ligation, pleuroperitoneal shunts or pleuredesis. Nowadays, for cases among which conservative therapies fail, treatment with octreotide has been reported to be beneficial with promising results. A neonate who developed chylothorax after surgery performed for congenital heart disease was treated successfully with octreotide. PMID:28058372

    There is no standard therapy in the management of postoperative pain control following corrective cardiac surgery of congenital heart disease. Assessment in the preverbal age is difficult. In a randomized study we compared a combined treatment of fentanyl and midazolam, given as continuous infusion versus single dose application. A pain assessment score was used to measure the effectiveness of analgosedation in addition to recording nurseries observations. Fentanyl and midazolam are an appropriate combination for postoperative pain treatment. Continuous application is considered to be more effective concerning basic anxiety, cumulative dosage and to avoid volume overload in infants and young children, following cardiac surgery; overdosage was not observed.

    Atrial fibrillation occurred in a 27-year-old patient with a history of globular cardiac enlargement since childhood. Because of the probable causal relationship between the preexisting heart disease-which was supposed to be an enlargement of the left atrium-and the rhythm disturbance, we recommended a surgical intervention. Cardiac surgery revealed a congenital aneurysm of the left atrial appendage which could be resected without any complication. Postoperatively, atrial fibrillation had returned to regular sinus rhythm. The bad prognosis with a high risk of systemic embolism is the reason why early cardiac surgery should be performed after diagnosis of this rare anomaly (20 reported cases) of the left atrium.

    Aim: In this study, it was aimed to determine the problems of the neonates who were diagnosed with congenital heart disease requiring early intervention in our hospital. Material and Methods: The files of the newborn babies with congenital heart disease requiring early intervention who were admitted to the neonatal intensive care unit of our hospital between January 2011 and January 2013 were evaluated retrospectively. In all cases, echocardiography and ‘’Score for Neonatal Acute Physiology-II” (SNAP-II) scoring were performed within the first day of admission. The data were interpreted using Number Cruncher Statistical System 2007 software. The statistical significance was set at p<0.05. Results: A total of 83 babies were included in the study. Forty six of the patients were male (55%), and 37 (45%) were female. Sixty eight percent of the patients were referred from the neighboring provinces and 32% were transferred from the centers within the city. The age range was between 0 and 28 (5.6±6.4 day) days. The SNAP-II scores upon admission ranged between 0 and 90 (mean: 20±20.3). None of the patients was diagnosed prenatally. The most common diagnoses included transposition of the great arteries (33.7%) and pulmonary atresia (19.3%). Nineteen (22%) patients were lost in the neonatal intensive care unit. There was a significant relationship between the mortality and the SNAP-II scores (p=0.0001) and use of vasopressors (p=0.004). The diagnosis, gender, use of alprostadil and age were not related to mortality. Three patients were discharged following planning of elective surgery and 60 patients were referred to a tertiary center by air ambulance. Conclusions: The results of our study indicated that prenatal diagnosis could not be made in neonates with congenital heart disease requiring intervention in our region. The mortality rates of these patients were related to the severity of the clinical status at presentation rather than to the age, gender and type of

    The number of patients surviving with congenital heart disease (CHD) has soared over the last 3 decades. Adults constitute the fastest-growing segment of the CHD population, now outnumbering children. Research to date on the heart-brain intersection in this population has been focused largely on neurodevelopmental outcomes in childhood and adolescence. Mutations in genes that are highly expressed in heart and brain may cause cerebral dysgenesis. Together with altered cerebral perfusion in utero, these factors are associated with abnormalities of brain structure and brain immaturity in a significant portion of neonates with critical CHD even before they undergo cardiac surgery. In infancy and childhood, the brain may be affected by risk factors related to heart disease itself or to its interventional treatments. As children with CHD become adults, they increasingly develop heart failure, atrial fibrillation, hypertension, diabetes mellitus, and coronary disease. These acquired cardiovascular comorbidities can be expected to have effects similar to those in the general population on cerebral blood flow, brain volumes, and dementia. In both children and adults, cardiovascular disease may have adverse effects on achievement, executive function, memory, language, social interactions, and quality of life. Against the backdrop of shifting demographics, risk factors for brain injury in the CHD population are cumulative and synergistic. As neurodevelopmental sequelae in children with CHD evolve to cognitive decline or dementia during adulthood, a growing population of CHD can be expected to require support services. We highlight evidence gaps and future research directions.

    Background The heart develops under reduced and varying oxygen concentrations, yet there is little understanding of oxygen metabolism in the normal and mal‐development of the heart. Here we used a novel reagent, the ODD‐Luc hypoxia reporter mouse (oxygen degradation domain, ODD) of Hif‐1α fused to Luciferase (Luc), to assay the activity of the oxygen sensor, prolyl hydroxylase, and oxygen reserve, in the developing heart. We tested the role of hypoxia‐dependent responses in heart development by targeted inactivation of Hif‐1α. Methods and Results ODD‐Luciferase activity was 14‐fold higher in mouse embryonic day 10.5 (E10.5) versus adult heart and liver tissue lysates. ODD‐Luc activity decreased in 2 stages, the first corresponding with the formation of a functional cardiovascular system for oxygen delivery at E15.5, and the second after birth consistent with complete oxygenation of the blood and tissues. Reduction of maternal inspired oxygen to 8% for 4 hours caused minimal induction of luciferase activity in the maternal tissues but robust induction in the embryonic tissues in proportion to the basal activity, indicating a lack of oxygen reserve, and corresponding induction of a hypoxia‐dependent gene program. Bioluminescent imaging of intact embryos demonstrated highest activity in the outflow portion of the E13.5 heart. Hif‐1α inactivation or prolonged hypoxia caused outflow and septation defects only when targeted to this specific developmental window. Conclusions Low oxygen concentrations and lack of oxygen reserve during a critical phase of heart organogenesis may provide a basis for vulnerability to the development of common septation and conotruncal heart defects.

    Background— Hyaluronan (HA) is required for endothelial-to-mesenchymal transition and normal heart development in the mouse. Heart abnormalities in hyaluronidase 2 (HYAL2)–deficient (Hyal2−/−) mice and humans suggested removal of HA is also important for normal heart development. We have performed longitudinal studies of heart structure and function in Hyal2−/− mice to determine when, and how, HYAL2 deficiency leads to these abnormalities. Methods and Results— Echocardiography revealed atrial enlargement, atrial tissue masses, and valvular thickening at 4 weeks of age, as well as diastolic dysfunction that progressed with age, in Hyal2−/− mice. These abnormalities were associated with increased HA, vimentin-positive cells, and fibrosis in Hyal2−/− compared with control mice. Based on the severity of heart dysfunction, acute and chronic groups of Hyal2−/− mice that died at an average of 12 and 25 weeks respectively, were defined. Increased HA levels and mesenchymal cells, but not vascular endothelial growth factor in Hyal2−/− embryonic hearts, suggest that HYAL2 is important to inhibit endothelial-to-mesenchymal transition. Consistent with this, in wild-type embryos, HYAL2 and HA were readily detected, and HA levels decreased with age. Conclusions— These data demonstrate that disruption of normal HA catabolism in Hyal2−/− mice causes increased HA, which may promote endothelial-to-mesenchymal transition and proliferation of mesenchymal cells. Excess endothelial-to-mesenchymal transition, resulting in increased mesenchymal cells, is the likely cause of morphological heart abnormalities in both humans and mice. In mice, these abnormalities result in progressive and severe diastolic dysfunction, culminating in heart failure. PMID:28196902

    Congenital heart disease (CHD) is the most common birth defect, affecting about 0.8% of live births. Advances in recent decades have allowed >85% of children with CHD to survive to adulthood, creating a growing population of adults with CHD. Little information exists regarding survival, demographics, late outcomes, and comorbidities in this emerging group, and multiple barriers impede research in adult CHD. The National Heart, Lung, and Blood Institute and the Adult Congenital Heart Association convened a multidisciplinary working group to identify high-impact research questions in adult CHD. This report summarizes the meeting discussions in the broad areas of CHD-related heart failure, vascular disease, and multisystem complications. High-priority subtopics identified included heart failure in tetralogy of Fallot, mechanical circulatory support/transplantation, sudden cardiac death, vascular outcomes in coarctation of the aorta, late outcomes in single-ventricle disease, cognitive and psychiatric issues, and pregnancy.

    Paralysis of diaphragm on one or, exceptionally, both sides is a common cause of delayed recovery and excessive morbidity following pediatric cardiac surgery. The consequences of this complication after all forms of congenital heart surgery in newborns and young infants can be potentially serious. The impact of diaphragmatic palsy on the physiology after single ventricle palliations is particularly significant. It is necessary for all professionals taking care of children with heart disease to be familiar with the etiology, diagnosis, and management of this condition. Early recognition and prompt management of diaphragmatic palsy can potentially reduce the duration of mechanical ventilation and intensive care in those who develop this complication. This review summarizes the anatomy of the phrenic nerves, reasons behind the occurrence of diaphragmatic palsy, and suggests practical guidelines for management. PMID:20814476

    Our understanding of the genetics of congenital heart disease (CHD) is rapidly expanding; however, many questions, particularly those relating to sporadic forms of disease, remain unanswered. Massively parallel sequencing technology has made significant contributions to the field, both from a diagnostic perspective for patients and, importantly, also from the perspective of disease mechanism. The importance of de novo variation in sporadic disease is a recent highlight, and the genetic link between heart and brain development has been established. Furthermore, evidence of an underlying burden of genetic variation contributing to sporadic and familial forms of CHD has been identified. Although we are still unable to identify the cause of CHD for most patients, recent findings have provided us with a much clearer understanding of the types of variants and their individual contributions and collectively mark an important milestone in our understanding of both familial and sporadic forms of disease.

    Energy imbalance in infants and children with congenital heart disease (CHD) is common and influenced by age, underlying cardiac diagnoses, and presence or absence of congestive heart failure. During the surgical hospitalization period, these children are prone to nutritional deterioration due to stress of surgery, anesthetic/perfusion techniques, and postoperative care. Poor nutrition is associated with increased perioperative morbidity and mortality. This review aims to examine various aspects of nutrition in critically ill children with CHD, including (1) energy expenditure, (2) perioperative factors that contribute to energy metabolism, (3) bedside practices that are potentially able to optimize nutrient delivery, and (4) medium- to long-term impact of energy balance on clinical outcomes. We propose a nutrition algorithm to optimize nutrition of these children in the perioperative period where improvements in nutrition status will likely impact surgical outcomes.

    Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital Heart Disease (CHD) patients. 134 genes were tested in the Drosophila heart using RNAi-based gene silencing. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional, and developmental roles for more than 70 genes, including a subgroup encoding histone H3K4 modifying proteins. We also demonstrated the use of Drosophila to evaluate cardiac phenotypes resulting from specific, patient-derived alleles of candidate disease genes. We describe the first high throughput in vivo validation system to screen candidate disease genes identified from patients. This approach has the potential to facilitate development of precision medicine approaches for CHD and other diseases associated with genetic factors.

    Recent studies have identified the genetic underpinnings of a growing number of diseases through targeted exome sequencing. However, this strategy ignores the large component of the genome that does not code for proteins, but is nonetheless biologically functional. To address the possible involvement of regulatory variation in congenital heart diseases (CHDs), we searched for regulatory mutations impacting the activity of TBX5, a dosage-dependent transcription factor with well-defined roles in the heart and limb development that has been associated with the Holt-Oram syndrome (heart-hand syndrome), a condition that affects 1/100 000 newborns. Using a combination of genomics, bioinformatics and mouse genetic engineering, we scanned ∼700 kb of the TBX5 locus in search of cis-regulatory elements. We uncovered three enhancers that collectively recapitulate the endogenous expression pattern of TBX5 in the developing heart. We re-sequenced these enhancer elements in a cohort of non-syndromic patients with isolated atrial and/or ventricular septal defects, the predominant cardiac defects of the Holt-Oram syndrome, and identified a patient with a homozygous mutation in an enhancer ∼90 kb downstream of TBX5. Notably, we demonstrate that this single-base-pair mutation abrogates the ability of the enhancer to drive expression within the heart in vivo using both mouse and zebrafish transgenic models. Given the population-wide frequency of this variant, we estimate that 1/100 000 individuals would be homozygous for this variant, highlighting that a significant number of CHD associated with TBX5 dysfunction might arise from non-coding mutations in TBX5 heart enhancers, effectively decoupling the heart and hand phenotypes of the Holt-Oram syndrome.

    Objective—To examine the evolving role of specialised outpatient services for adult patients with congenital heart disease.
Design—A retrospective analysis of all patients attending the Toronto Congenital Cardiac Centre for Adults over three corresponding three month periods in 1987, 1992, and 1997.
Setting—A tertiary referral centre.
Main outcome measures—Patient demographics, residence, medical and surgical history, type and source of referral, and investigations performed.
Results—In all, 570 patients were seen at the clinic during these three periods. There was a 44% and a 269% increase in workload between 1987 to 1992 and 1992 to 1997, respectively. There was a steady fall in mean age of patients seen at the clinic with time (38.5, 33.6, and 31.7 years in 1987, 1992, and 1997, respectively, p < 0.001). New referrals from community cardiologists and family physicians increased more in relative terms than did referrals from the Hospital for Sick Children, Toronto (6.7%, 15%, and 37.5%, p = 0.02). There was a steady increase in patients with previous reparative surgery (48.9%, 59.2%, and 69.2%, p < 0.002). The proportion of patients with previous reoperations also increased (2.3%, 10%, and 9.2%, p < 0.01). Echocardiography remained the predominant method of diagnosis. The diagnostic mix did not change with time.
Conclusions—Over the past 10 years there has been a large increase in adults with congenital heart disease requiring and seeking specialised care in a tertiary health centre, with a concomitant evolution of referral patterns. These data may be helpful in planning of similar paediatric and adult cardiac services for this expanding population.

    A double-chambered right ventricle (DCRV) is a rare congenital heart disease and an uncommon cause of congestive cardiac failure. An anomalous muscle band divides the right ventricle into two cavities, causing variable degrees of obstruction. Echocardiography is considered a useful method for the diagnosis of this pathology, especially in children. An eight-year-old patient with a small ventricular septal defect (VSD) and double-chambered right ventricle presented with a history of palpitations, easy fatigability and recurrent fever. On presentation, she had features of congestive cardiac failure. A complete diagnosis was initially missed with transthoracic two-dimensional (2-D) echocardiography but later obtained based on transthoracic 2-D echocardiography with Doppler facility. This was confirmed with cardiac catheterisation. The patient was referred for surgical correction, which was successful. Due to the rarity of this condition and the consequences of missing the diagnosis, we present this case in order to highlight the rarity of this congenital heart disease in childhood.

    Congenital heart defects (CHDs) are the most common major birth defects and the leading cause of death from congenital malformations. The etiology remains largely unknown, though genetic variants clearly contribute. In a previous study, we identified a large copy number variant (CNV) that deleted 46 genes in a patient with a malalignment type ventricular septal defect (VSD). The CNV included the gene NTRK3 encoding neurotrophic tyrosine kinase receptor C (TrkC), which is essential for normal cardiogenesis in animal models. To evaluate the role of NTRK3 in human CHDs, we studied 467 patients with related heart defects for NTRK3 mutations. We identified four missense mutations in four patients with VSDs that were not found in ethnically matched controls and were predicted to be functionally deleterious. Functional analysis using neuroblastoma cell lines expressing mutant TrkC demonstrated that one of the mutations (c.278C>T, p.T93M) significantly reduced autophosphorylation of TrkC in response to ligand binding, subsequently decreasing phosphorylation of downstream target proteins. In addition compared to WT, three of the four cell lines expressing mutant TrkC showed altered cell growth in low-serum conditions without supplemental NT-3. These findings suggest a novel pathophysiological mechanism involving NTRK3 in the development of VSDs. PMID:25196463

    Objective. The objective of this study was to determine the frequency of pulmonary arterial hypertension (PAH) in congenital heart disease (CHD) with an isolated, large left-to-right shunt and to indicate the factors in the development of PAH. Methods. The pressure measurements in the cardiac chambers and the calculations based on the Fick's principle were compared among 3 separate groups of patients, respectively, with PAH, with hyperkinetic pulmonary hypertension (HPH), and with neither PAH nor HPH. Results. PAH was diagnosed in 30 (12.3%) patients, HPH in 35 (14.4%), while 177 (73.1%) were free of either. The highest risk for the development of PAH was found in the presence of perimembranous ventricular septal defect. A statistically significant difference was seen among these groups as to their left atrial pressure (p = 0.005) and the mean pulmonary arterial pressure (PAPmean; p < 0.001). While a correlation was present between RpI on one hand and age on the other (p = 0.014), a multiple linear regression could not evidence any correlation among age (p = 0.321), gender (p = 0.929). Conclusion. Our findings do not allow establishing a correlation between the duration of the high pulmonary flow and pulmonary vascular resistance increase or PAH development in isolated left-to-right shunts with congenital heart diseases.

    Extracorporeal membrane oxygenation (ECMO) has become the standard technique of mechanical support for the failing circulation following repair of congenital heart lesions. The objective of this study was to identify predictors of survival in patients requiring postcardiotomy ECMO. The Aristotle score, a method developed to evaluate quality of care based on complexity, was investigated as a potential predictor of outcome. Between 2003 and 2005, 37 patients required ECMO following corrective surgery for congenital heart disease. Records were reviewed retrospectively with emphasis on factors affecting survival to discharge. The comprehensive Aristotle complexity score was calculated for each patient. Overall, 28 patients (76%) survived to decannulation and 17 patients (46%) survived to discharge. There were 24 (65%) neonates and 10 patients (27%) with single ventricle physiology, with a hospital survival of 42% (10 of 24) and 50% (5 of 10), respectively. Univariate factors associated with survival included Aristotle score, duration of support, reexploration, multiple organ failure, and number of complications. Age, weight, and single-ventricle physiology were not significant. In a logistic regression model, an Aristotle score < 14 was identified as a predictor of survival (OR 0.12, CI 0.02-0.87). The Aristotle score is predictive of outcome in patients requiring postcardiotomy ECMO and may serve as a uniform criterion when comparing and evaluating quality of care and performance in this complex patient population.

    The objective of this study was to characterize morphine glucuronidation in infants and children following cardiac surgery for possible treatment individualization in this population. Twenty children aged 3 days to 6 years, admitted to the cardiovascular intensive care unit after congenital heart surgery, received an intravenous (IV) loading dose of morphine (0.15 mg/kg) followed by subsequent intermittent IV bolus doses based on a validated pain scale. Plasma samples were collected over 6 h after the loading dose and randomly after follow-up doses to measure morphine and its major metabolite concentrations. A population pharmacokinetic model was developed with the non-linear mixed effects software NONMEM. Parent disposition was adequately described by a linear two-compartment model. Effect of growth (size and maturation) on morphine parameters was accounted for by allometric body weight-based models. An intermediate compartment with Emax model best characterized glucuronide concentrations. Glomerular filtration rate was identified as a significant predictor of glucuronide formation time delay and maximum concentrations. Clearance of morphine in children with congenital heart disease is comparable to that reported in children without cardiac abnormalities of similar age. Children 1-6 months of age need higher morphine doses per kilogram to achieve an area under concentration-time curve comparable to that in older children. Pediatric patients with renal failure receiving morphine therapy are at increased risk of developing opioid toxicity due to accumulation of morphine metabolites.

    Advances in catheter-based interventions in structural and congenital heart disease have mandated an increased demand for three-dimensional (3D) visualisation of complex cardiac anatomy. Despite progress in 3D imaging modalities, the pre- and periprocedural visualisation of spatial anatomy is relegated to two-dimensional flat screen representations. 3D printing is an evolving technology based on the concept of additive manufacturing, where computerised digital surface renders are converted into physical models. Printed models replicate complex structures in tangible forms that cardiovascular physicians and surgeons can use for education, preprocedural planning and device testing. In this review we discuss the different steps of the 3D printing process, which include image acquisition, segmentation, printing methods and materials. We also examine the expanded applications of 3D printing in the catheter-based treatment of adult patients with structural and congenital heart disease while highlighting the current limitations of this technology in terms of segmentation, model accuracy and dynamic capabilities. Furthermore, we provide information on the resources needed to establish a hospital-based 3D printing laboratory.

    2015-10-01

    Children with cyanotic congenital heart disease (CCHD) have complex alterations in their whole blood composition and coagulation profile due to long-standing hypoxemia. Secondary erythrocytosis is an associated physiological response intended to increase circulating red blood cells and oxygen carrying capacity. However, this response is frequently offset by an increase in whole blood viscosity that paradoxically reduces blood flow and tissue perfusion. In addition, the accompanying reduction in plasma volume leads to significant deficiencies in multiple coagulation proteins including platelets, fibrinogen and other clotting factors. On the one hand, these patients may suffer from severe hyperviscosity and subclinical 'sludging' in the peripheral vasculature with an increased risk of thrombosis. On the other hand, they are at an increased risk for postoperative hemorrhage due to a complex derangement in their hemostatic profile. Anesthesiologists caring for children with CCHD and secondary erythrocytosis need to understand the pathophysiology of these alterations and be aware of available strategies that lessen the risk of bleeding and/or thrombosis. The aim of this review is to provide an updated analysis of the systemic effects of long-standing hypoxemia in children with primary congenital heart disease with a specific focus on secondary erythrocytosis and hemostasis.

    Background and Objectives Temporal trends in mortality from congenital heart disease (CHD) vary among regions. It is therefore necessary to study this problem in each country. In Mexico, congenital anomalies were responsible for 24% of infant mortality in 2013 and CHD represented 55% of total deaths from congenital anomalies among children under 1 year of age. The objectives of this study were to analyze the trends in infant mortality from CHD in Mexico (1998 to 2013), its specific causes, age at death and associated socio-demographic factors. Methods Population-based study which calculated the compounded annual growth rate of death rom CHD between 1998 and 2013. Specific causes, age at which death from CHD occurred and risk factors associated with mortality were analyzed for the year 2013. Results Infant mortality from CHD increased 24.8% from 1998 to 2013 (114.4 to 146.4/ 100,000 live births). A total of 3,593 CHD deaths occurred in 2013; the main causes were CHD with left-to-right shunt (n = 487; 19.8/100,000 live births) and cyanotic heart disease (n = 410; 16.7/100,000). A total of 1,049 (29.2%) deaths from CHD occurred during the first week of life. Risk factors associated with mortality from CHD were, in order of magnitude: non-institutional birth, rural area, birth in a public hospital and male sex. Conclusions Mortality from CHD has increased in Mexico. The main causes were CHD with left-to-right shunt, which are not necessarily fatal if treated promptly. Populations vulnerable to death from CHD were identified. Approximately one-third of the CHD occurred during the first week of life. It is important to promote early diagnosis, especially for non-institutional births. PMID:26937635

    OBJECTIVE To evaluate the trends in survival for infants with critical congenital heart defects (CCHDs) and to examine the potential impact of timing of diagnosis and other prognostic factors on survival. METHODS We performed a retrospective population-based cohort study in infants born with structural congenital heart defects (CHDs) between 1979 and 2005 and ascertained by the Metropolitan Atlanta Congenital Defects Program. We estimated Kaplan-Meier survival probabilities for 12 CCHD phenotypes by birth era and timing of diagnosis among infants without noncardiac defects or chromosomal disorders and used stratified Cox proportional hazards models to assess potential prognostic factors. RESULTS Of 1 056 541 births, there were 6965 infants with CHDs (1830 with CCHDs). One-year survival was 75.2% for those with CCHDs (n = 1336) vs 97.1% for those with noncritical CHDs (n = 3530; P < .001). One-year survival for infants with CCHDs improved from 67.4% for the 1979–1993 birth era to 82.5% for the 1994–2005 era (P < .001). One-year survival was 71.7% for infants with CCHDs diagnosed at ≤1 day of age (n = 890) vs 82.5% for those with CCHDs diagnosed at >1 day of age (n = 405; P < .001). There was a significantly higher risk of 1-year mortality for infants with an earlier birth era, earlier diagnosis, and low birth weight and whose mothers were <30 years old. CONCLUSIONS One-year survival for infants with CCHDs has been improving over time, yet mortality remains high. Later diagnosis is associated with improved 1-year survival. These benchmark data and identified prognostic factors may aid future evaluations of the impact of pulse oximetry screening on survival from CCHDs. PMID:23610203

    Background: Fetal congenital heart anomalies are the most common congenital anomalies in live births. Fetal echocardiography (FECG) is the only prenatal diagnostic approach used to detect fetal congenital heart disease (CHD). FECG is not widely used, and the antenatal diagnosis rate of CHD varies considerably. Thus, mastering the anatomical characteristics of different kinds of CHD is critical for ultrasound physicians to improve FECG technology. The aim of this study is to investigate the applications of a fetal CHD anatomic database in FECG teaching and training program. Methods: We evaluated 60 transverse section databases including 27 types of fetal CHD built in the Prenatal Diagnosis Center in Peking University People's Hospital. Each original database contained 400–700 cross-sectional digital images with a resolution of 3744 pixels × 5616 pixels. We imported the database into Amira 5.3.1 (Australia Visage Imaging Company, Australia) three-dimensional (3D) software. The database functions use a series of 3D software visual operations. The features of the fetal CHD anatomical database were analyzed to determine its applications in FECG continuing education and training. Results: The database was rebuilt using the 3D software. The original and rebuilt databases can be displayed dynamically, continuously, and synchronically and can be rotated at arbitrary angles. The sections from the dynamic displays and rotating angles are consistent with the sections in FECG. The database successfully reproduced the anatomic structures and spatial relationship features of different fetal CHDs. We established a fetal CHD anatomy training database and a standardized training database for FECG. Ultrasound physicians and students can learn the anatomical features of fetal CHD and FECG through either centralized training or distance education. Conclusions: The database of fetal CHD successfully reproduced the anatomic structures and spatial relationship of different kinds of

    Purpose A link has been created between the Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) and the Congenital Heart Surgeons’ Society Database (CHSS-D). Five matrices have been created that facilitate the automated identification of patients who are potentially eligible for the five active CHSS studies using the STS-CHSD. These matrices are now used to (1) estimate the denominator of patients eligible for CHSS studies and (2) compare “eligible and enrolled patients” to “potentially eligible and not enrolled patients” to assess the generalizability of CHSS studies. Methods The matrices were applied to 40 consenting institutions that participate in both the STS-CHSD and the CHSS to (1) estimate the denominator of patients that are potentially eligible for CHSS studies, (2) estimate the completeness of enrollment of patients eligible for CHSS studies among all CHSS sites, (3) estimate the completeness of enrollment of patients eligible for CHSS studies among those CHSS institutions participating in each CHSS cohort study, and (4) compare “eligible and enrolled patients” to “potentially eligible and not enrolled patients” to assess the generalizability of CHSS studies. The matrices were applied to all participants in the STS-CHSD to identify patients who underwent frequently performed operations and compare “eligible and enrolled patients” to “potentially eligible and not enrolled patients” in following five domains: (1) age at surgery, (2) gender, (3) race, (4) discharge mortality, and (5) postoperative length of stay. Completeness of enrollment was defined as the number of actually enrolled patients divided by the number of patients identified as being potentially eligible for enrollment. Results For the CHSS Critical Left Ventricular Outflow Tract Study (LVOTO) study, for the Norwood procedure, completeness of enrollment at centers actively participating in the LVOTO study was 34%.

    Most patients with single ventricle (SV) congenital heart disease are expected to survive to adulthood. Women with SV are often counseled against pregnancy; however, data on pregnancies in these women are lacking. We sought to evaluate in-hospital outcomes of pregnancy in women with SV. We used nationally representative data from the 1998 to 2012 National Inpatient Sample to identify women ≥18 years of age admitted to the hospital with International Classification of Diseases-9th Revision codes for an intrauterine pregnancy and a diagnosis of hypoplastic left heart syndrome, tricuspid atresia, or common ventricle. A matched comparison group without a diagnosis of congenital heart disease or pulmonary hypertension was identified from the database. National estimates of hospitalizations were calculated. Length of stay, hospital charges, and complications were analyzed and compared between groups. Charge data were adjusted to 2012 dollars. There were 282 admissions of pregnant women with SV (69% with deliveries) and 1,405 admissions in the control group (88% with deliveries). Vaginal delivery was more common in SV (74% vs 71%, p <0.001). Length of stay (4.1 ± 0.91 vs 2.8 ± 0.18 days, p <0.001) and charges ($30,787 ± 8,109 vs $15,536 ± 1,006, p <0.0001) were higher in the SV group. Complications occurred in most SV admissions and were more common in the SV group than in the control group. No deaths occurred. Cardiovascular complications occurred in 25% of pregnancy-related hospitalizations, although in-hospital pregnancy-related death is rare. Vaginal delivery is common in these patients. These data suggest that pregnancy and vaginal delivery can be tolerated in women with SV, although the risk for a cardiovascular event is significantly higher than in the general population.

    ABSTRACT Background: Mothers play a key role in caring for their sick children. Their experiences of care were influenced by culture, rules, and the system of health and care services. There are few studies on maternal care of children with congenital heart disease. Also, each of them has studied a particular aspect of care. The present research aimed to understand care experiences of mothers of children with congenital heart disease. Methods: A conventional content analysis was used to obtain rich data. The goal of content analysis is “to provide knowledge and deeper understanding of the phenomenon under the study”. The study was conducted in Kerman, Iran in 2014, on mothers of children with CHD. The purposive sampling technique was used to select the participants. Participants were 14 mothers of children with CHD and one father and one nurse of open heart surgery unit, from two hospitals affiliated with Kerman University of Medical Sciences. Eighteen semi-structured interviews were constructed. Data were analyzed using conventional content analysis. MAXQDA 2007 software (VERBI GmbH, Berlin, Germany) was used to classify and manage the coding. Constant comparative method was done for data analysis. The reliability and validity of the findings, including the credibility, confirm ability, dependability, and transferability, were assessed. Results: According to the content analysis, the main theme was the catastrophic burden of child care on mothers that included three categories: 1) the tension resulting from the disease, 2) involvement with internal thoughts, and 3) difficulties of care process Conclusion: The results of this study may help health care professionals to provide supportive and educational packages to the patients, mothers and Family members until improving the management of patient’s care.

    BACKGROUND Maternal type 1 and 2 diabetes mellitus are strongly associated with high rates of severe structural birth defects, including congenital heart defects. Studies in type 1 diabetic embryopathy animal models have demonstrated that cellular stress-induced apoptosis mediates the teratogenicity of maternal diabetes leading to congenital heart defect formation. However, the mechanisms underlying maternal type 2 diabetes mellitus–induced congenital heart defects remain largely unknown. OBJECTIVE We aim to determine whether oxidative stress, endoplasmic reticulum stress, and excessive apoptosis are the intracellular molecular mechanisms underlying maternal type 2 diabetes mellitus–induced congenital heart defects. STUDY DESIGN A mouse model of maternal type 2 diabetes mellitus was established by feeding female mice a high-fat diet (60% fat). After 15 weeks on the high-fat diet, the mice showed characteristics of maternal type 2 diabetes mellitus. Control dams were either fed a normal diet (10% fat) or the high-fat diet during pregnancy only. Female mice from the high-fat diet group and the 2 control groups were mated with male mice that were fed a normal diet. At E12.5, embryonic hearts were harvested to determine the levels of lipid peroxides and superoxide, endoplasmic reticulum stress markers, cleaved caspase 3 and 8, and apoptosis. E17.5 embryonic hearts were harvested for the detection of congenital heart defect formation using India ink vessel patterning and histological examination. RESULTS Maternal type 2 diabetes mellitus significantly induced ventricular septal defects and persistent truncus arteriosus in the developing heart, along with increasing oxidative stress markers, including superoxide and lipid peroxidation; endoplasmic reticulum stress markers, including protein levels of phosphorylated-protein kinase RNA-like endoplasmic reticulum kinase, phosphorylated-IRE1α, phosphorylated-eIF2α, C/EBP homologous protein, and binding immunoglobulin

    2017-01-01

    Three basic principles provide the rationale for the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (CHSD) public reporting initiative: (1) Variation in congenital and pediatric cardiac surgical outcomes exist. (2) Patients and their families have the right to know the outcomes of the treatments that they will receive. (3). It is our professional responsibility to share this information with them in a format they can understand. The STS CHSD public reporting initiative facilitates the voluntary transparent public reporting of congenital and pediatric cardiac surgical outcomes using the STS CHSD Mortality Risk Model. The STS CHSD Mortality Risk Model is used to calculate risk-adjusted operative mortality and adjusts for the following variables: age, primary procedure, weight (neonates and infants), prior cardiothoracic operations, non-cardiac congenital anatomic abnormalities, chromosomal abnormalities or syndromes, prematurity (neonates and infants), and preoperative factors (including preoperative/preprocedural mechanical circulatory support [intraaortic balloon pump, ventricular assist device, extracorporeal membrane oxygenation, or cardiopulmonary support], shock [persistent at time of surgery], mechanical ventilation to treat cardiorespiratory failure, renal failure requiring dialysis and/or renal dysfunction, preoperative neurological deficit, and other preoperative factors). Operative mortality is defined in all STS databases as (1) all deaths, regardless of cause, occurring during the hospitalization in which the operation was performed, even if after 30 days (including patients transferred to other acute care facilities); and (2) all deaths, regardless of cause, occurring after discharge from the hospital, but before the end of the 30(th) postoperative day. The STS CHSD Mortality Risk Model has good model fit and discrimination with an overall C statistics of 0.875 and 0.858 in the development sample and the validation sample

    Mutations in the Nkx2-5 gene are a main cause of congenital heart disease. Several studies have addressed the phenotypic consequences of disrupting the Nkx2-5 gene locus, although animal models to date failed to recapitulate the full spectrum of the human disease. Here, we describe a new Nkx2-5 point mutation murine model, akin to its human counterpart disease–generating mutation. Our model fully reproduces the morphological and physiological clinical presentations of the disease and reveals an understudied aspect of Nkx2-5–driven pathology, a primary right ventricular dysfunction. We further describe the molecular consequences of disrupting the transcriptional network regulated by Nkx2-5 in the heart and show that Nkx2-5–dependent perturbation of the Wnt signaling pathway promotes heart dysfunction through alteration of cardiomyocyte metabolism. Our data provide mechanistic insights on how Nkx2-5 regulates heart function and metabolism, a link in the study of congenital heart disease, and confirms that our models are the first murine genetic models to our knowledge to present all spectra of clinically relevant adult congenital heart disease phenotypes generated by NKX2-5 mutations in patients.

    Nosocomial infections still remain a serious problem in patients undergoing open heart surgery. The aim of the study was to determine the incidence, etiology and main risk factors of nosocomial infections (NI) following cardiac surgery in congenital heart diseases population. Retrospective case study was conducted. 387 patients with congenital heart disease (CHD), who underwent cardiac surgery from January 2007 to December 2008 were studied. The age of the most patients varied between 1 day to 15 years, 73 patients (18,8%) were older than 15 years. All 387 patients underwent cardiac surgery. The rate of NI was 16%. The most common infections were bloodstream infections (BSI) (7,75%) and respiratory tract infections (7%) respectively. The rate of NI was higher in patients under 1 year of age, after urgent surgery and urgent reoperation, long cardiopulmonary bypass (CPB) and aortic cross-clamp time, also in patients with prolonged mechanical ventilation, massive haemotransfusion, with open heart bone after surgery, reintubation, hospitalization in another hospital during last three month. It was concluded that the most common nosocomial infection after cardiac surgery congenital heart diseases in Georgian population was blood stream infection. The main risk factors of NI in the same setting were age under 1 year, urgent surgery, urgent reoperation, long CPB and aortic cross-clamp time, long duration of mechanical ventilation, massive haemotransfusion, open heart bone after surgery, reintubation, hospitalization in another hospital during last three month.

    The role of hemodynamics in early heart development is poorly understood. In order to successfully assess the impact of hemodynamics on development, we need to monitor and perturb blood flow, and quantify the resultant effects on morphology. Here, we have utilized cardiac optical pacing to create regurgitant flow in embryonic hearts and OCT to quantify regurgitation percentage and resultant morphology. Embryonic quail in a shell-less culture were optically paced at 3 Hz (well above the intrinsic rate or 1.33-1.67 Hz) on day 2 of development (3-4 weeks human) for 5 minutes. The pacing fatigued the heart and led to a prolonged period (> 1 hour) of increased regurgitant flow. Embryos were kept alive until day 3 (cardiac looping - 4-5 weeks human) or day 8 (4 chambered heart - 8 weeks human) to quantify resultant morphologic changes with OCT. All paced embryos imaged at day 3 displayed cardiac defects. The extent of regurgitant flow immediately after pacing was correlated with cardiac cushion size 24-hours post pacing (p-value < 0.01) with higher regurgitation leading to smaller cushions. Almost all embryos (16/18) surviving to day 8 exhibited congenital heart defects (CHDs) including 11/18 with valve defects, 5/18 with ventricular septal defects and 5/18 with hypoplastic right ventricles. Our data suggests that regurgitant flow leads to smaller cushions, which develop into abnormal valves and septa. Our model produces similar phenotypes as found in our fetal alcohol syndrome and velo-cardio-facial/DiGeorge syndrome models suggesting that hemodynamics plays a role in these syndromes as well. Utilizing OCT and optical pacing to understand hemodynamics in development is an important step towards determining CHD mechanisms and ultimately developing earlier treatments.

    2012-10-01

    Cardiac resynchronization therapy (CRT) has been shown to improve mortality and morbidity in adults with refractory heart failure and prolonged QRS-duration. Recent research data suggest that the therapeutic benefit is related to the effect of CRT on interventricular and intraventricular dyssynchrony associated with electrical dyssynchrony. However, around 30-40% of the patients do not respond to CRT when device implantation is based only on QRS-duration. It was hoped that improved description of mechanical dyssynchrony using imaging techniques, might result in improved identification of patients who could benefit from CRT. Different methods have been proposed but a recent multicenter prospective echocardiographic study (PROSPECT) was disappointing. Applying adult criteria for CRT treatment to children and adults with acquired and congenital heart disease is even more challenging due to the age-dependency of QRS-duration and the wide variety of underlying diseases including different ventricular morphology that can result in heart failure. In this review we will overview the adult and pediatric data of CRT treatment and propose a mechanistic approach that could potentially be helpful in trying to identify those patients who might benefit from the treatment.

    The etiology for the majority of congenital heart defects (CHD) is unknown. We identified a patient with unbalanced atrioventricular septal defect (AVSD) and hypoplastic left ventricle who harbored an ~0.3 Mb monoallelic deletion on chromosome 3p14.1. The deletion encompassed the first four exons of FOXP1, a gene critical for normal heart development that represses cardiomyocyte proliferation and expression of Nkx2.5. To determine whether FOXP1 mutations are found in patients with CHD, we sequenced FOXP1 in 82 patients with AVSD or hypoplastic left heart syndrome. We discovered two patients who harbored a heterozygous c.1702C>T variant in FOXP1 that predicted a potentially deleterious substitution of a highly conserved proline (p.Pro568Ser). This variant was not found in 287 controls but is present in dbSNP at a 0.2% frequency. The orthologous murine Foxp1 p.Pro596Ser mutant protein displayed deficits in luciferase reporter assays and resulted in increased proliferation and Nkx2.5 expression in cardiomyoblasts. Our data suggest that haploinsufficiency of FOXP1 is associated with human CHD.

    Outcomes after discharge in children requiring tracheostomy after cardiac surgery have not been fully described. A retrospective, single-center study was performed on all children <18 years of age requiring both tracheostomy and surgery for congenital heart disease from January 2002 to May 2015. Forty-six tracheostomies were placed after surgery and four before. Single-ventricle anatomy was present in 12 (33%) patients. Incidence of tracheostomy after heart surgery increased from 0.8% the first half of the study period to 2% the second half. Median time between cardiac surgery and tracheostomy was 58 days. The most common indication for tracheostomy was multifactorial (30%) followed by airway malacia (22%). Median length to follow-up for survivors was 3.9 years (range 0.4-11.8 years). Survival to hospital discharge was 72%, and intermediate survival was 48%. Survival in those with systemic to pulmonary artery shunts at the time of tracheostomy was 22% compared to 59% for those with biventricular anatomy. Heart failure and multiple indications for tracheostomy were associated with worse outcome. There was no difference in survival for those discharged with a ventilator compared to those that were not. The most common cause of death after discharge was tracheostomy tube dislodgement/obstruction, accounting for 5 of 11 that died. Survival with a tracheostomy after cardiac surgery is poor, and children with systemic to pulmonary artery shunts are at especially high risk of death.

    Our objective was to determine whether the Seattle Heart Failure Model (SHFM) differentiates patients with adult congenital heart disease (ACHD) at high versus low risk for cardiovascular outcomes and poor exercise capacity. The ACHD population is growing and presents increasingly for care in the community and at tertiary centers. Few strategies exist to identify the patients with ACHD at high risk for heart failure and mortality.We studied 153 adults with transposition of the great arteries, Ebstein anomaly, tetralogy of Fallot, double outlet right ventricle, and single ventricle from 2 ACHD centers. The primary outcome was cardiovascular death, with a secondary composite outcome of death, transplant, ventricular assist device, cardiovascular admission, and treatment for arrhythmia. We defined risk groups based on SHFM 5-year predicted survival: high (predicted survival <70%), intermediate (70% to 85%), and low risk (>85%). Ten patients had the primary outcome of death, and 46 the combined end point. The hazard of death in the SHFM high- versus the intermediate-risk group was 7.09 (95% confidence interval 1.5 to 33.4, p = 0.01; no deaths in the low-risk group) and the hazard of the composite outcome between the high- versus low-risk group was 6.64 (95% confidence interval 2.5 to 17.6, p = 0.0001). Kaplan-Meier survival analysis showed greater probability of all-cause mortality (p = 0.003) in the high-risk group. In conclusion, the SHFM can help identify subjects with ACHD at risk for adverse outcome and poor cardiopulmonary efficiency. This may add to the care of patients with ACHD in the community and streamline care at tertiary centers.

    Objective To determine an accurate estimate of the prevalence of congenital heart defects (CHD) using current standard diagnostic modalities. Study design We obtained data on infants with CHD delivered during 1998–2005 identified by the Metropolitan Atlanta Congenital Defects Program, an active, population-based birth defects surveillance system. Physiologic shunts in infancy and shunts associated with prematurity were excluded. Selected infant and maternal characteristics of the cases were compared with those of the overall birth cohort. Results From 1998–2005 there were 398 140 births, of which 3240 infants had CHD, for an overall prevalence of 81.4/10 000 births. The most common CHD were muscular ventricular septal defect, perimembranous ventricular septal defect, and secundum atrial septal defect, with prevalence of 27.5, 10.6, and 10.3/10 000 births, respectively. The prevalence of tetralogy of Fallot, the most common cyanotic CHD, was twice that of transposition of the great arteries (4.7 vs. 2.3/10 000 births). Many common CHD were associated with older maternal age and multiple-gestation pregnancy; several were found to vary by sex. Conclusion This study, using a standardized cardiac nomenclature and classification, provides current prevalence estimates of the various CHD subtypes. These estimates can be used to assess variations in prevalence across populations, time or space. PMID:18657826

    Cardiac defects are the most frequent congenital malformations, with an incidence estimated between 4 and 12 per 1000 newborns. Their etiology is multifactorial and might be attributed to genetic predispositions and environmental factors. Since 1990 these types of pathologies have been associated with 22q11 microdeletion. In this study, the frequency of microdeletion 22q11 was determined in 61 patients with non-syndromic congenital heart disease. DNA was extracted from peripheral blood and TUPLE1 and STR D10S2198 genes were amplified by multiplex PCR and visualized in agarose gels. Gene content was quantified by densitometry. Three patients were found with microdeletion 22q11, representing a 4.9% frequency. This microdeletion was associated with two cases of Tetralogy of Fallot and a third case with atrial septal defect (ASD). In conclusion, the frequency for microdeletion 22q11 in the population analyzed was 4.9%. The cases that presented Teratology of Fallot had a frequency for this microdeletion of 7.4% and for ASD of 11.1%.

    We aimed to assess the frequency of chromosomal abnormalities among infants with congenital heart defects (CHDs) in an analysis of population-based surveillance data. We reviewed data from the Metropolitan Atlanta Congenital Defects Program, a population-based birth-defects surveillance system, to assess the frequency of chromosomal abnormalities among live-born infants and fetal deaths with CHDs delivered from January 1, 1994, to December 31, 2005. Among 4430 infants with CHDs, 547 (12.3%) had a chromosomal abnormality. CHDs most likely to be associated with a chromosomal abnormality were interrupted aortic arch (type B and not otherwise specified; 69.2%), atrioventricular septal defect (67.2%), and double-outlet right ventricle (33.3%). The most common chromosomal abnormalities observed were trisomy 21 (52.8%), trisomy 18 (12.8%), 22q11.2 deletion (12.2%), and trisomy 13 (5.7%). In conclusion, in our study, approximately 1 in 8 infants with a CHD had a chromosomal abnormality. Clinicians should have a low threshold at which to obtain testing for chromosomal abnormalities in infants with CHDs, especially those with certain types of CHDs. Use of new technologies that have become recently available (e.g., chromosomal microarray) may increase the identified contribution of chromosomal abnormalities even further.

  18. Ethical questions arising from counselling in fetal complex congenital heart disease.

    2012-09-01

    Fetal ultrasounds are almost routinely carried out during pregnancies in Western society. It has led to the in-utero diagnosis of congenital malformations, and in skilled hands, complex congenital heart disease which carries a significant morbidity and definite mortality. That has allowed for counselling of the affected parents who may have the option of whether to continue with the pregnancy. Such counselling, however is not without its difficulties and ethical dilemmas. They range from attempting to inform at times very distressed parents, the nature and implications of their fetal abnormality, the outcome and risks involved in the interventions which may be required, while at the same time being asked to prognosticate the long-term outcomes. Such counselling at times is based on incomplete information obtained or refers to lesions that may evolve during the rest of the pregnancy. In addition, the information provided is unable to factor in possible advances that may occur in the future which may alter the quality of life and outcomes of the affected individuals. Other members of the concerned extended family may wish to have a say in the decision making process. The clinicians themselves may wish to take into account not only the burden to the family emotionally and in terms of the possible interventions - surgical or otherwise, hospitalisations, the risks of complications, and so on - but also the financial and other costs borne by the community. This article highlights the problems encountered and raises ethical questions to encourage discussion to guide the clinicians involved.

    Neonates with critical congenital heart disease (CCHD) are vulnerable to malnutrition during the post-operative period due to hypermetabolism and hypercatabolism. To improve nutritional outcomes during hospitalization, a nurse led post-operative enteral feeding protocol was implemented at a large U.S. children's hospital. During an eight-month implementation period, twenty-one neonates met protocol inclusion criteria. Days for neonates to achieve goal caloric feedings (120kcal/kg/day) were decreased. A one-way repeated measures analysis of variance showed serum albumin levels and serial anthropometric measurements improved significantly throughout hospitalization (p<0.005). Results from this quality improvement project show standardizing nutritional care for neonates with CCHD during the post-operative period is an effective way to improve nutritional outcomes and shorten length of hospital stay.

    We employ a hybrid diffuse correlation spectroscopy (DCS) and near-infrared spectroscopy (NIRS) monitor for neonates with congenital heart disease (n=33). The NIRS-DCS device measured changes during hypercapnia of oxyhemoglobin, deoxyhemoglobin, and total hemoglobin concentrations; cerebral blood flow (rCBFDCS); and oxygen metabolism (rCMRO2). Concurrent measurements with arterial spin-labeled magnetic resonance imaging (rCBFASL-MRI, n=12) cross-validate rCBFDCS against rCBFASL-MRI, showing good agreement (R=0.7, p=0.01). The study demonstrates use of NIRS-DCS on a critically ill neonatal population, and the results indicate that the optical technology is a promising clinical method for monitoring this population.

    RV hypertrophy (RVH) is one of the triggers of RV failure in congenital heart disease (CHD). Therefore, improving our understanding of the cellular and molecular basis of this pathology will help in developing strategic therapeutic interventions to enhance patient benefit in the future. This review describes the potential mechanisms that underlie the transition from RVH to RV failure. In particular, it addresses structural and functional remodelling that encompass contractile dysfunction, metabolic changes, shifts in gene expression and extracellular matrix remodelling. Both ischaemic stress and reactive oxygen species production are implicated in triggering these changes and will be discussed. Finally, RV remodelling in response to various CHDs as well as the potential role of biomarkers will be addressed.

    Introduction Congenital heart diseases (CHD) are commonly associated with genetic defects. Our study aimed at determining the occurrence and pattern of CHD association with genetic defects among pediatric patients in Rwanda. Methods A total of 125 patients with clinical features suggestive of genetic defects were recruited. Echocardiography and standard karyotype studies were performed in all patients. Results CHDs were detected in the majority of patients with genetic defects. The commonest isolated CHD was ventricular septal defect found in many cases of Down syndrome. In total, chromosomal abnormalities represented the majority of cases in our cohort and were associated with various types of CHDs. Conclusion Our findings showed that CHDs are common in Rwandan pediatric patients with genetic defects. These results suggest that a routine echocardiography assessment combined with systematic genetic investigations including standard karyotype should be mandatory in patients presenting characteristic clinical features in whom CHD is suspected to be associated with genetic defect.

    We present the unique case of an 8 month old infant who required extracorporeal membrane oxygenation (ECMO) after neonatal repair of tetralogy of Fallot. While on ECMO, he developed grade 3 intraventricular hemorrhage resulting in hydrocephalus requiring ventriculoperitoneal (VP) shunt placement at 5 months of life. He presented to cardiology clinic with a 2-month history of poor weight gain, tachypnea, and grunting and was found to have a large right sided pleural effusion. This was proven to be cerebrospinal fluid (CSF) accumulation secondary to poor peritoneal absorption with subsequent extravasation of CSF into the thoracic cavity via a diaphragmatic defect. After diaphragm repair, worsening ascites from peritoneal malabsorption led to shunt externalization and ultimate conversion to a ventriculoatrial (VA) shunt. This is the second reported case of VA shunt placement in a child with congenital heart disease and highlights the need to consider CSF extravasation as the cause of pleural effusions in children with VP shunts.

    The family of an infant born with a congenital heart defect is challenged by both the short- and long-term implications of the diagnosis and the neonatal intensive care unit (NICU) hospitalization. Nurses are in a key position to support these families as they deal with the psychological, emotional, and financial impact of the NICU experience. Understanding how families perceive the NICU environment and their grief in losing the desired healthy baby provides the NICU nurse with the knowledge to engage in self-reflection on her or his interpersonal style and caregiving attitudes. Utilizing the concepts and principles of family-centered care and relationship-based practice, nurses can work together with the families to determine how to best meet the families' needs and to find the resources to support them. Families and colleagues appreciate nurses who demonstrate expertise in this approach to family-centered care. This appreciation leads to greater job satisfaction and decreased job-related stress.

    Arrhythmias are a major cause of morbidity, mortality and hospital admission in adults with congenital heart disease (CHD). The etiology of arrhythmias in this population is often multifactorial and includes electrical disturbances as part of the underlying defect, surgical intervention or hemodynamic abnormalities. Despite the numerous existing arrhythmia management tools including drug therapy, pacing and ablation, management of arrhythmias in adults with CHD remains difficult and challenging. Owing to improvement in mapping and ablation techniques, ablation and arrhythmia surgery are being performed more frequently in adults with CHD. However, there is little information on the long-term results of these treatment strategies. The purpose of this article is therefore to review the available data on nonpharmacological treatment of cardiac arrhythmias in adult patients with CHD and to give an overview of the available data on the early and late outcomes of these treatment strategies.

    Synthetic patches and fixed grafts currently used in the repair of congenital heart defects are nonliving, noncontractile, and not electrically responsive, leading to increased risk of complication, reoperation, and sudden cardiac death. Studies suggest that tissue-engineered patches made from living, functional cells could grow with the patient, facilitate healing, and help recover cardiac function. In this paper, we review the research into possible sources of cardiomyocytes and other cardiac cells, including embryonic stem cells, induced pluripotent stem cells, mesenchymal stem cells, adipose-derived stem cells, umbilical cord blood cells, amniotic fluid-derived stem cells, and cardiac progenitor cells. Each cell source has advantages, but also has technical hurdles to overcome, including heterogeneity, functional maturity, immunogenicity, and pathogenicity. Additionally, biomaterials used as patch materials will need to attract and support desired cells and induce minimal immune responses. PMID:26379417

    We employ a hybrid diffuse correlation spectroscopy (DCS) and near-infrared spectroscopy (NIRS) monitor for neonates with congenital heart disease (n=33). The NIRS-DCS device measured changes during hypercapnia of oxyhemoglobin, deoxyhemoglobin, and total hemoglobin concentrations; cerebral blood flow (rCBFDCS); and oxygen metabolism (rCMRO2). Concurrent measurements with arterial spin-labeled magnetic resonance imaging (rCBFASL-MRI, n=12) cross-validate rCBFDCS against rCBFASL-MRI, showing good agreement (R=0.7, p=0.01). The study demonstrates use of NIRS-DCS on a critically ill neonatal population, and the results indicate that the optical technology is a promising clinical method for monitoring this population.

    Objective To assess the level of partner relationship satisfaction among mothers of children with different severity of congenital heart defects (CHD) compared with mothers in the cohort. Methods Mothers of children with mild, moderate, or severe CHD (n = 182) and a cohort of mothers of children without CHD (n = 46,782) from the Norwegian Mother and Child Cohort Study were assessed at 5 time points from pregnancy to 36 months postpartum. A 5-item version of the Relationship Satisfaction scale was used, and relevant covariates were explored. Results The trajectories of relationship satisfaction among mothers of children with varying CHD severity did not differ from the trajectories in the cohort. All women in the cohort experienced decreasing relationship satisfaction from 18 months after delivery up to 36 months after delivery. Conclusions Having a child with CHD, regardless of severity, does not appear to exacerbate the decline in relationship satisfaction.

    A history of oral contraceptive use, hormonal pregnancy tests, prescribed hormones and other drugs was obtained from 390 mothers of infants with congenital heart disease and 1254 mothers of normal infants in Massachusetts. The data show a small positive association between estrogen/progesterone exposure and cardiac malformation, the prevalence ratio estimate of exposed to non-exposed being 1.5 (90 per cent confidence limits are 1.0, 2.1). No association was evident, however, between hormones and trunco-conal or any other class of defect among the cases, an observation which casts doubt on a causal relationship betweem hormones and cardiovascular malformations. Several other drugs were reported more frequently by cases' mothers. These include: ampicillin; aspirin; a combined anti-nausea agent (doxylamine succinate, dicyclomine hydrochloride and pyridoxine hydrochloride); chlordiazopoxide, codeine, diazepam, diphenylhydantoin; insulin; phenobarbital; phenothiazine; phenylephrine; and tetracycline.

    Congenital heart disease (CHD), a prevalent birth defect occurring in 1% of newborns, likely results from aberrant expression of cardiac developmental genes. Mutations in a variety of cardiac transcription factors, developmental signalling molecules and molecules that modify chromatin cause at least 20% of disease, but most CHD remains unexplained. We employ RNAseq analyses to assess allele-specific expression (ASE) and biallelic loss-of-expression (LOE) in 172 tissue samples from 144 surgically repaired CHD subjects. Here we show that only 5% of known imprinted genes with paternal allele silencing are monoallelic versus 56% with paternal allele expression—this cardiac-specific phenomenon seems unrelated to CHD. Further, compared with control subjects, CHD subjects have a significant burden of both LOE genes and ASE events associated with altered gene expression. These studies identify FGFBP2, LBH, RBFOX2, SGSM1 and ZBTB16 as candidate CHD genes because of significantly altered transcriptional expression. PMID:27670201

    Critical congenital heart disease (CCHD) screening is rapidly becoming the standard of care in the United States after being added to the Recommended Uniform Screening Panel (RUSP) in 2011. Newborn screens typically do not require affirmative parental consent. In fact, most states allow parents to exempt their baby from receiving the required screen on the basis of religious or personally held beliefs. There are many ethical considerations implicated with allowing parents to exempt their child from newborn screening for CCHD. Considerations include the treatment of religious exemptions in our current legal system, as well as medical and ethical principles in relation to the rights of infants. Although there are significant benefits to screening newborns for CCHD, when a parent refuses for religious or personal beliefs, in the case of CCHD screening, the parental decision should stand.

  12. Is Pulse Oximetry Useful for Screening Neonates for Critical Congenital Heart Disease at High Altitudes?

    2016-06-01

    Now that pulse oximetry is used widely to screen for critical congenital heart disease, it is time to consider whether this screening method is applicable to those who live at high altitudes. Consideration of basic physical principles and reports from the literature indicate that not only is the 95 % cutoff point for arterial oxygen saturation incorrect at high altitudes, but the lower saturations are accompanied by greater variability and therefore there is the possibility of a greater percentage of false-positive screening tests at high altitudes. Because of ethnic differences in response to high altitudes, normative data will have to be collected separately in different countries and perhaps for different ethnic groups.

    There are limited data on the relationship between the administered dose of recombinant factor seven (rFVIIa) and the development of adverse clinical outcomes after congenital heart surgery. This single institution case series reports on dosing, adverse events, and blood product usage after the administration of rFVIIa in the congenital heart surgery patient population. A retrospective review identified 16 consecutive pediatric patients at an academic, free-standing, children’s hospital who received rFVIIa to curtail bleeding following congenital heart surgery between April 2004 and June 2012. Patients were assessed for survival to hospital discharge versus in-hospital mortality and the presence or absence of a major neurological event during inpatient hospitalization. The median age at surgery was 6.8 months (range: 3 days–42 years). Seven patients (44%) survived to hospital discharge and nine patients (56%) died. The cause of mortality included major neurological events (44%), uncontrolled bleeding (33%), and sepsis (23%). Eight patients (50%) required extracorporeal membrane oxygenation support following congenital heart surgery. The median cumulative rFVIIa dose administered was 97 mcg/kg, and the median cumulative amount of blood products administered was 452 ml/kg. In conclusion, this case series underscores the need to prospectively evaluate the effect that rFVIIa has on patient survival and the incidence of adverse events, including thrombotic and major neurological events, in congenital heart surgery patients. Ideally, a randomized, multicenter study would provide the sufficient numbers of patients and events to test these relationships. PMID:25544818

    The objective of this study is to evaluate the yield of genetic testing in infants with congenital heart disease, who undergo surgical intervention prior to one year of age, and develop a cost-effective strategy to screen infants with congenital heart disease for genetic conditions while providing standard of care. 409 charts of patients with congenital heart disease, who underwent surgical intervention prior to one year of age, were retrospectively reviewed for cytogenetic testing results. 278 patients underwent cytogenetic testing, and 89.6 % of these patients had more than one cytogenetic test completed. The most commonly encountered chromosomal anomaly within the sample was Down Syndrome (12.5 %), followed by 22q11.2 Deletion Syndrome (4.6 %). G-Banded Karyotypes were abnormal in 10.5 % of patients, fluorescence in situ hybridization (FISH) probe for 22q11.2 deletion was abnormal in 7.1 % of patients. SNP microarray testing showed the highest yield and was abnormal in 33 % of patients. Based on the data at our institution, a more directed approach of genetic screening with only microarray would have saved our institution approximately $101, 200 on the 103 patients who underwent genetic evaluation with microarray reviewed. Screening infants with congenital heart disease for 22q11.2 deletion with FISH resulted in a loss of approximately $32,000 per 100 patients at our institution. Institutions should develop microarray-based protocols for genetic screening in patients with congenital heart disease with the anticipation of adding lesion-specific single gene testing as single gene testing becomes routinely available.

    BACKGROUND AND OBJECTIVE New Jersey was the first state to implement legislatively mandated newborn pulse oximetry screening (POxS) in all licensed birthing facilities to detect critical congenital heart defects (CCHDs). The objective of this report was to evaluate implementation of New Jersey’s statewide POxS mandate. METHODS A 2-pronged approach was used to collect data on infants screened in all New Jersey birthing facilities from August 31, 2011, through May 31, 2012. Aggregate screening results were submitted by each birthing facility. Data on failed screens and clinical characteristics of those newborns were reported to the New Jersey Birth Defects Registry (NJBDR). Three indicators were used to distinguish the added value of mandated POxS from standard clinical care: prenatal congenital heart defect diagnosis, cardiology consultation or echocardiogram indicated or performed before PoxS, or clinical findings at the time of POxS warranting a pulse oximetry measurement. RESULTS Of 75 324 live births in licensed New Jersey birthing facilities, 73 320 were eligible for screening, of which 99% were screened. Forty-nine infants with failed POxS were reported to the NJBDR, 30 of whom had diagnostic evaluations solely attributable to the mandated screening. Three of the 30 infants had previously unsuspected CCHDs and 17 had other diagnoses or non-CCHD echocardiogram findings. CONCLUSIONS In the first 9 months after implementation, New Jersey achieved a high statewide screening rate and established surveillance mechanisms to evaluate the unique contribution of POxS. The screening mandate identified 3 infants with previously unsuspected CCHDs that otherwise might have resulted in significant morbidity and mortality and also identified other significant secondary targets such as sepsis and pneumonia.

    Thymectomy is performed routinely in infants undergoing cardiothoracic surgery. Children post-sternotomy have decreased numbers of T lymphocytes, although the mechanisms involved and long-term consequences of this have not been defined. We hypothesized that lymphopenia in patients with adult congenital heart disease (ACHD) would be reflective of premature T cell maturation and exhaustion. Adults with ACHD who had sternotomy to repair congenital heart disease as infants (<1 year) and age-matched ACHD patients without prior sternotomy were studied using polychromatic flow cytometry interrogating markers of lymphocyte maturation, exhaustion and senescence. Group differences were analyzed using Mann-Whitney U and Fisher's exact tests. Eighteen ACHD patients aged 21-40 years participated: 10 cases and 8 controls. Median age at sternotomy for cases was 52 days. Cases and controls were matched for age (28.9 vs. 29.1 years; p = 0.83), gender (p = 0.15) and race (p = 0.62) and had similar case complexity. Cases had a lower mean percentage of cytotoxic CD8 lymphocytes compared to controls (26.8 vs. 33.9 %; p = 0.016), with fewer naive, undifferentiated CD8 T cells (31.0 vs. 53.6 %; p = 0.027). CD8 cells expressing PD1, a marker of immune exhaustion, trended higher in cases versus controls (25.6 vs. 19.0 %; p = 0.083). Mean percentage of CD4 cells was higher in cases versus controls (65.6 vs. 59.6 %; p = 0.027), without differences in CD4 T cell maturation subtype. In summary, ACHD patients who undergo sternotomy as infants exhibit differences in T lymphocyte composition compared to ACHD controls, suggesting accelerated immunologic exhaustion. Investigation is warranted to assess the progressive nature and clinical impact of this immune phenotypic change.

    Management of warfarin in pediatric patients remains a clinical challenge. Warfarin may be administered after congenital heart surgery, and the risks of morbidity can be high. Currently, no data exist to describe the initiation of warfarin and the risk factors for morbidity in post-congenital heart surgery patients. This study aimed to characterize the time required to reach anticoagulation for patients administered warfarin therapy after cardiac surgery and to identify and characterize the risk factors for supratherapeutic anticoagulation and adverse events after warfarin initiation. This retrospective study reviewed all patients between 2006 and 2011 who received warfarin anticoagulation after cardiac surgery at our institution. Factors associated with a prolonged time required to reach an international normalized ratio (INR) of 2 and factors related to supratherapeutic anticoagulation (INR ≥ 4) were identified. The inclusion criteria were met by 59 patients. The median time required to reach an INR of at least 2 after initiation of warfarin was 2 days (interquartile range (IQR), 2-4). The only groups that required a significantly longer time to reach an INR of 2 were those with a postoperative delay in initiation of warfarin and those receiving heparin anticoagulation before and during warfarin initiation. Nine patients experienced an INR of 4 or more. However, no thrombotic events occurred, and significant bleeding was uncommon. In the largest reported group of patients undergoing anticoagulation after cardiac surgery, warfarin was well tolerated across all age groups. The median time required to reach an INR of 2 after loading with warfarin was 2 days, and adverse events were uncommon.

    Overt congenital heart defects (CHD) affect over 40% of newborns with Down syndrome. On the hypothesis that genetic variation on chromosome 21 determines this clinical variability, we studied a CHD candidate locus (COL6A1) on 21q22.3. We studied three RFLP loci in COL6A1 in 37 families of known British/Irish population of ancestral origin, and in population-matched controls. Each family had a child with trisomy 21 with or without accompanying congenital heart defect (CHD). Parental and meiotic origin of nondisjunction were determined using peri-centromeric markers. For the analysis, we considered groups of families with trisomic children with and without CHD, and subsets of nondisjoining and disjoining parents. Parental genotypes at nine control RFLP loci on chromosome 21 showed no association with CHD in the trisomic child. By contrast, parental genotypes at all three individual RFLP loci within COL6A1 showed statistically significant association with the trisomic child`s CHD status. Pairwise consideration of these loci in groups of families of trisomic children with and without CHD showed subsets of nondisjoining and disjoining parents to have different linkage disequilibrium patterns at these loci than population-matched controls. This suggests that the COL6A1 alleles of the parents are not representative of the population as a whole. Consideration of all three loci together as haplotypes supports this conclusion. Four results suggest that a functional mutation within, or in linkage disequilibrium with COL6A1 influences CHD outcome in trisomy 21.

    Prenatal diagnosis of congenital heart defects (CHDs) is increasingly common, but it is still unclear whether it translates to improved postoperative outcomes. We performed a retrospective cohort study of all infants (aged <1 year) who underwent surgery for CHDs from 2006 to 2011 at a single institution. Primary outcomes were in-hospital and 1-year mortality rates. Secondary outcomes were readmission within 30 days of discharge, postoperative length of intensive care unit and hospital stay, unplanned reoperation, and extracorporeal membrane oxygenation use. We used chi-square analyses, Wilcoxon rank-sum tests, Kaplan-Meier survival curves, and adjusted Cox proportional hazards models to compare outcomes. Of the 1,642 patients with CHDs, 539 (33%) were diagnosed prenatally. Patients with prenatal diagnoses were of a younger age and less weight at the time of surgery, had greater Risk Adjustment for Congenital Heart Surgery scores, and were more likely to be white, to have an identified syndrome, or to be born at term. Compared with those diagnosed postnatally, those diagnosed prenatally had a significantly higher unadjusted 1-year mortality rate (11% vs 5.5%, respectively, p = 0.03). Controlling for weight, surgical severity, race, age at surgery, prematurity, and the presence or absence of genetic syndrome, patients with prenatal diagnoses had significantly greater mortality at 1 year (adjusted hazard ratio 1.5, p = 0.03), as well as significantly longer intensive care unit and hospital stays. Infants with CHDs diagnosed prenatally had worse outcomes compared with those diagnosed postnatally. Prenatal diagnosis likely captures patients with more severe phenotypes within given surgical risk categories and even within diagnoses and thus may be an important prognostic factor when counseling families.

    Background Infants with complex congenital heart disease requiring surgical intervention within the first days or weeks of life may be the most seriously ill infants needing intensive nursing and medical care immediately after birth. Skin to skin contact (SSC) is well-accepted and practiced as a positive therapeutic intervention in premature infants, but is not routinely offered to infants in cardiac intensive care units. Physiologic effects of SSC in the congenital heart disease population must be examined before recommending incorporation of SSC into standard care routines. Objective The purpose of this case study was to describe the physiologic response to a single session of SSC in an 18-day-old infant with hypoplastic left heart syndrome. Methods Repeated measures of heart rate, respiratory rate, oxygen saturation, blood pressure, and temperature were recorded 30 minutes prior to SSC, during SSC (including interruptions for bottle and breast feedings), and 10 minutes after SSC was completed. Results All physiologic parameters were clinically acceptable throughout the 135-minute observation. Conclusion This case study provides beginning evidence that SSC is safe in full-term infants following surgery for complex congenital heart disease. Further research with a larger sample is needed to examine effects of SSC on infant physiology before surgery and earlier in the postoperative time period as well as on additional outcomes such as length of stay, maternal-infant interaction, and neurodevelopment.

    OBJECTIVE: To determine the frequence and profile of congenital heart defects in Down syndrome patients referred to a pediatric cardiologic center, considering the age of referral, gender, type of heart disease diagnosed by transthoracic echocardiography and its association with pulmonary hypertension at the initial diagnosis. METHODS: Cross-sectional study with retrospective data collection of 138 patients with Down syndrome from a total of 17,873 records. Descriptive analysis of the data was performed, using Epi-Info version 7. RESULTS: Among the 138 patients with Down syndrome, females prevailed (56.1%) and 112 (81.2%) were diagnosed with congenital heart disease. The most common lesion was ostium secundum atrial septal defect, present in 51.8%, followed by atrioventricular septal defect, in 46.4%. Ventricular septal defects were present in 27.7%, while tetralogy of Fallot represented 6.3% of the cases. Other cardiac malformations corresponded to 12.5%. Pulmonary hypertension was associated with 37.5% of the heart diseases. Only 35.5% of the patients were referred before six months of age. CONCLUSIONS: The low percentage of referral until six months of age highlights the need for a better tracking of patients with Down syndrome in the context of congenital heart disease, due to the high frequency and progression of pulmonary hypertension.

    Summary Objective to describe the epidemiological data of the population born with the diagnosis of Congenital Heart Disease (CHD); to compare diagnoses made using fetal echocardiography with the findings from postnatal echocardiography or anatomopathological examination of the heart; and to evaluate mortality among newborns that underwent surgical treatment. Methods this was a cohort study with information gathered from the medical records of the pregnant women and their newborns diagnosed with CHD during the fetal or postnatal periods, between January 2008 and December 2012. Means, standard deviations and maximum and minimum values were calculated for the quantitative variables. Relative and absolute values were calculated for the qualitative variables. The heart malformations were categorized in four groups: complex lesions, significant lesions, minor lesions and others. Results we detected postnatal incidence of CHD of 1.9% at our service. The mean maternal age was 28.3 years and 10 (21.3%) of the pregnant women were ≥ 35 years old. The mean gestational age at the time of performing the fetal echocardiogram was 27.8 weeks. Mean gestational age at delivery was 38 weeks, and the mean weight of the newborns was 2,644.5 grams. Regarding the diagnosis of CHD, there were: 23 complex lesions (39%); 15 significant lesions (26%); 10 minor lesions (17%); 4 other lesions (7%) and 6 normal anatomies (10%). The diagnosis of CHD made on the fetus and postnatally coincided in 77.6% of the cases. A total of 27 patients (60%) underwent surgery, and the outcome was neonatal death in five cases. Conclusion we detected postnatal incidence of CHD of 1.9%, and it was more common among older pregnant women and with late detection in the intrauterine period. Complex heart diseases predominated, thus making it difficult to have a good result regarding neonatal mortality rates. PMID:25332754

    While the XYY and XXYY syndromes have been several time described in patients, the combination of both syndromes in an individual is a rare event and may result in a severe phenotype. In the present observation, a boy with congenital scoliosis due to segmented thoracic hemivertebra associated with radioulnar synostosis and congenital heart disease is described. Chromosome G-banding and FISH analysis demonstrated a de novo mosaic karyotype 48, XXYY/47, XYY in this patient.

    The involvement of the hemodynamic expertise in the operating room led to the development of new strategies aimed to improve both early and long-term outcome of patients with congenital heart disease. During the last decade, with the aim of preserving the pulmonary valve function, we embarked on a new surgical approach, which combines surgical and interventional techniques, which are performed in the operating room. We believe that the preservation of the pulmonary valve function can be extended to any patients with classic tetralogy of Fallot and other selected patients with congenital pulmonary valve hypoplasia and dysfunction.

    The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision. 3D echocardiography enables to guide precisely percutaneous procedure. The morphology of the valve leaflets, chordal support apparatus, papillary muscle and the annulus are particularly well described in 3D and allows assessment of the regurgitation before repair and after as well for the common valve of the atrioventricular septal defect or in the Ebstein anomaly. Complex heart diseases such as double outlet right ventricle are suitable to a tridimensional assessment to plan surgical strategy. 3D printing, fusion imaging in cathlab and automated volume quantification embody recent innovations of new techniques in congenital heart disease.

    Atlas-based analysis methods rely on the morphological similarity between the atlas and target images, and on the availability of labelled images. Problems can arise when the deformations introduced by pathologies affect the similarity between the atlas and a patient's image. The aim of this work is to exploit the morphological dissimilarities between atlas databases and pathological images to diagnose the underlying clinical condition, while avoiding the dependence on labelled images. We propose a voxelwise atlas rating approach (VoxAR) relying on multiple atlas databases, each representing a particular condition. Using a local image similarity measure to assess the morphological similarity between the atlas and target images, a rating map displaying for each voxel the condition of the atlases most similar to the target is defined. The final diagnosis is established by assigning the condition of the database the most represented in the rating map. We applied the method to diagnose three different conditions associated with dextro-transposition of the great arteries, a congenital heart disease. The proposed approach outperforms other state-of-the-art methods using annotated images, with an accuracy of 97.3% when evaluated on a set of 60 whole heart MR images containing healthy and pathological subjects using cross validation.

    Objective To determine the prevalence of rheumatic heart disease (RHD) and congenital heart disease (CHD) using clinical and echocardiographic criteria in rural and urban school children in Andhra Pradesh, South India. Materials and methods A total of 4213 school children between 5 and 16 years of age were screened. 1177 were from rural schools and 3036 from urban schools. Prevalence of RHD and CHD was estimated. Results Clinically RHD was present in 3 (prevalence 0.7/1000). Using echocardiography RHD was detected in 32 (7.6/1000), 11 (7.3/1000) from rural and 21 (7/1000) from urban schools. (P = 0.000, O.R = 0.093 and C.I. = 0.023–0.317). Total prevalence of RHD is 8.3/1000. Clinically CHD was present in 39 (9.2/1000) children, rural 9 (7.6/1000) and urban 30 (9.9/1000). Using echocardiography CHD was detected in 44 (10.4/1000) children, rural 11 (9.3/1000) and urban 33 (10.8/1000). Conclusion RHD was detected several fold using echocardiographic screening than by clinical examination alone. Longitudinal follow-up of children with echocardiographically diagnosed subclinical RHD is needed. PMID:24023464

    Purpose To assess the contribution of multiple risk factors for two congenital heart defects—hypoplastic left heart syndrome (HLHS) and tetralogy of Fallot (TOF). Methods We used data from the National Birth Defects Prevention Study (1997–2011) to estimate average adjusted population attributable fractions for several recognized risk factors, including maternal prepregnancy overweight–obesity, pregestational diabetes, age, and infant sex. Results There were 594 cases of isolated simple HLHS, 971 cases of isolated simple TOF, and 11,829 controls in the analysis. Overall, 57.0% of HLHS cases and 37.0% of TOF cases were estimated to be attributable to risk factors included in our model. Among modifiable HLHS risk factors, maternal pre-pregnancy overweight–obesity accounted for the largest proportion of cases (6.5%). Among modifiable TOF risk factors, maternal prepregnancy overweight–obesity and maternal age of 35 years or older accounted for the largest proportions of cases (8.3% and 4.3%, respectively). Conclusions Approximately half of HLHS cases and one-third of TOF cases were estimated to be attributable to risk factors included in our models. Interventions targeting factors that can be modified may help reduce the risk of HLHS and TOF development. Additional research into the etiology of HLHS and TOF may reveal other modifiable risk factors that might contribute to primary prevention efforts. PMID:27894567

    Autoimmune AV block is usually seen in association with autoimmune antibodies in mother that cross the placenta and damage the AV node of fetus. A 24-year-old primigravida, diagnosed to have SLE, at 25 weeks period of gestation found to have fetal bradycardia. Her ANA was moderately positive, SS-A (Ro) antibodies and SS-B (La) antibodies were positive. Fetal ECHO showed no structural defect but heart rate was 55 - 60 beats per minute. She was put on dexamethasone (4 mg/day). She was lost on follow up and presented at term in emergency with labor pains and fetal bradycardia, underwent a lower segment caesarean section. Baby underwent a temporary cardiac pacing within 10 hours of birth followed by permanent pacing on day 3 of birth. Baby is doing well on follow up. Neonates with isolated congenital heart block who are monitored antenatally and delivered in a planned fashion at an institution capable of early pacing can have favorable outcomes.

    In the first part a prospective cohort study was reported to evaluate the efficacy and safety of a treatment protocol including plasma exchange (PE) or PE plus intravenous immunoglobulins (IVIG) or immunoadsorption (IA) plus IVIG administered in addition to conventional therapy to 22 pregnant women with high-risk APS. The results indicate that PE or IA treatments administered along with IVIG and conventional antithrombotic therapy could be a valuable and safe therapeutic option in pregnant APS women with triple antiphospholipid antibody positivity along with a history of thrombosis and/or one or more severe pregnancy complications. In the second part the efficacy and safety of PE combined with IVIG and steroids were evaluated for the treatment of 10 patients with autoimmune congenital heart block (CHB) by comparing maternal features, pregnancy outcome and side effects with those of 24 CHB patients treated with steroids only. The patients treated with the combined therapy showed a statistically significant regression of 2nd degree blocks, an increase in heart rate at birth and a significantly lower prevalence of pacing in the first year of life. Moreover, no side effects were observed except for a few steroid-related events. If these results are confirmed by large-scale studies, the apheretic procedures could lead to improved outcomes in the treatment of these devastating diseases.

    The Fontan operation is a surgical treatment for patients with severe congenital heart diseases, where a biventricular correction of the heart can't be achieved. In these cases, a uni-ventricular system is established. During the last step of surgery a tunnel segment is placed to connect the inferior caval vein directly with the pulmonary artery, bypassing the right atrium and ventricle. Thus, the existing ventricle works for the body circulation, while the venous blood is passively directed to the pulmonary arteries. Fontan tunnels can be placed intra- and extracardially. The location, length and shape of the tunnel must be planned accurately. Furthermore, if the tunnel is placed extracardially, it must be positioned between other anatomical structures without constraining them. We developed a software system to support planning of the tunnel location, shape, and size, making pre-operative preparation of the tunnel material possible. The system allows for interactive placement and adjustment of the tunnel, affords a three-dimensional visualization of the virtual Fontan tunnel inside the thorax, and provides a quantification of the length, circumferences and diameters of the tunnel segments. The visualization and quantification can be used to plan and prepare the tunnel material for surgery in order to reduce the intra-operative time and to improve the fit of the tunnel patch.

    Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital Heart Disease (CHD) patients. 134 genes were tested in the Drosophila heart using RNAi-based gene silencing. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional, and developmental roles for more than 70 genes, including a subgroup encoding histone H3K4 modifying proteins. We also demonstrated the use of Drosophila to evaluate cardiac phenotypes resulting from specific, patient-derived alleles of candidate disease genes. We describe the first high throughput in vivo validation system to screen candidate disease genes identified from patients. This approach has the potential to facilitate development of precision medicine approaches for CHD and other diseases associated with genetic factors.

    Congenital heart disease (CHD) is the most frequent birth defect, affecting 0.8% of live births. Many cases occur sporadically and impair reproductive fitness, suggesting a role for de novo mutations. Here we compare the incidence of de novo mutations in 362 severe CHD cases and 264 controls by analysing exome sequencing of parent-offspring trios. CHD cases show a significant excess of protein-altering de novo mutations in genes expressed in the developing heart, with an odds ratio of 7.5 for damaging (premature termination, frameshift, splice site) mutations. Similar odds ratios are seen across the main classes of severe CHD. We find a marked excess of de novo mutations in genes involved in the production, removal or reading of histone 3 lysine 4 (H3K4) methylation, or ubiquitination of H2BK120, which is required for H3K4 methylation. There are also two de novo mutations in SMAD2, which regulates H3K27 methylation in the embryonic left-right organizer. The combination of both activating (H3K4 methylation) and inactivating (H3K27 methylation) chromatin marks characterizes 'poised' promoters and enhancers, which regulate expression of key developmental genes. These findings implicate de novo point mutations in several hundreds of genes that collectively contribute to approximately 10% of severe CHD.

    The right ventricle (RV) is of lesser importance in acquired heart disease, but its role is of increasing importance in congenital heart disease (CHD). Despite major progress being made, precise measurements of the RV are challenging because of its peculiar anatomical structure that is not adaptable to any planar geometrical assumption. This is particularly true in adult patients with CHD where the RV shape eludes any standardization, it may assume various morphologies, and its modality of contraction depends on previous surgical treatment and/or pathophysiological conditions. However, reliable and repeatable quantification of RV dimensions and function for these patients are essential to provide appropriate timing for intervention to optimize outcomes. In this population, echocardiographic evaluation should not be limited to an observational and subjective functional assessment of the RV but must provide quantitative values repeatable and clinically reliable to help the decision-making process. The aim of this review was to discuss the echocardiographic approach to the RV in adult patients with CHD in general and in specific cases of pressure or volume overload.

    Congenital heart disease (CHD) is the most frequent birth defect, affecting 0.8% of live births1. Many cases occur sporadically and impair reproductive fitness, suggesting a role for de novo mutations. By analysis of exome sequencing of parent-offspring trios, we compared the incidence of de novo mutations in 362 severe CHD cases and 264 controls. CHD cases showed a significant excess of protein-altering de novo mutations in genes expressed in the developing heart, with an odds ratio of 7.5 for damaging mutations. Similar odds ratios were seen across major classes of severe CHD. We found a marked excess of de novo mutations in genes involved in production, removal or reading of H3K4 methylation (H3K4me), or ubiquitination of H2BK120, which is required for H3K4 methylation2–4. There were also two de novo mutations in SMAD2; SMAD2 signaling in the embryonic left-right organizer induces demethylation of H3K27me5. H3K4me and H3K27me mark `poised' promoters and enhancers that regulate expression of key developmental genes6. These findings implicate de novo point mutations in several hundred genes that collectively contribute to ~10% of severe CHD. PMID:23665959

    Chromosomal abnormalities and the 22q11 microdeletion are implicated in congenital heart defects (CHDs). This study was designed to detect these abnormalities in fetuses and determine the effect of genetic factors on CHD etiology. Between January 2010 and December 2011, 113 fetuses with CHD treated at the Beijing Obstetrics and Gynecology Hospital were investigated, using chromosome karyotyping of either amniotic fluid cell or umbilical cord blood cell samples. Fetuses with a normal result were then investigated for the 22q11 microdeletion by fluorescence in situ hybridization. Of the 113 patients, 12 (10.6%) exhibited chromosomal abnormalities, while 6 (5.3%) of the remaining 101 cases presented with a 22q11 microdeletion. The incidence of chromosomal abnormalities was significantly higher in the group of fetuses presenting with extracardiac malformations in addition to CHD (P<0.001), although the detection of the 22q11 microdeletion was not significantly different between the two groups (P=0.583). In addition, all fetuses with the 22q11 microdeletion occurred de novo. In conclusion, genetic factors are important in the etiology of CHD. Where fetuses present with cardiac defects, additional chromosomal analysis is required to detect extracardiac abnormalities. Fetuses with heart defects should also be considered for 22q11 microdeletion detection to evaluate fetal prognosis, particularly prior to surgery.

    Objective To determine the association between hospital costs and risk-adjusted inpatient mortality among children undergoing surgery for congenital heart disease (CHD) in U.S. acute-care hospitals. Data Sources/Study Settings Retrospective cohort study of 35,446 children in 2003, 2006, and 2009 Kids' Inpatient Database (KID). Study Design Cross-sectional logistic regression of risk-adjusted inpatient mortality and hospital costs, adjusting for a variety of patient-, hospital-, and community-level confounders. Data Collection/Extraction Methods We identified relevant discharges in the KID using the AHRQ Pediatric Quality Indicator for pediatric heart surgery mortality, and linked these records to hospital characteristics from American Hospital Association Surveys and community characteristics from the Census. Principal Findings Children undergoing CHD surgery in higher cost hospitals had lower risk-adjusted inpatient mortality (p = .002). An increase from the 25th percentile of treatment costs to the 75th percentile was associated with a 13.6 percent reduction in risk-adjusted mortality. Conclusions Greater hospital costs are associated with lower risk-adjusted inpatient mortality for children undergoing CHD surgery. The specific mechanisms by which greater costs improve mortality merit further exploration. PMID:24138064

    Trisomy 21, the chromosomal condition responsible for Down syndrome (DS, OMIM #190685), is the most common identifiable genetic cause of intellectual disability. Approximately half of all children with DS are born with a significant congenital heart defect (CHD), the most common of which is an atrioventricular septal defect (AVSD). As children with comorbid DS and CHD increasingly survive cardiac surgery, characterization of their early developmental trajectories is critical for designing early interventions to maximize individual potential. Herein, the developmental domains (cognitive, language, and motor) of children with DS and AVSD (DS + AVSD, n=12) were compared to children with DS and a structurally normal heart (DS – CHD, n=17) using the Bayley Scales of Infant and Toddler Development III. The DS + AVSD cohort mean age was relatively the same as controls with DS – CHD, 14.5 ±7.3 months compared with 14.1 ± 8.4 months, respectively. Although the motor domain was the only domain that showed a statistically significant difference between groups (p < .05), both cognitive standard scores (p = 0.63) and language composite standard scores (p = 0.10) were lower in the DS + AVSD cases compared with the DS – CHD controls although it is not statistically significant. Since this is the first study to examine the early developmental outcomes of children with DS + AVSD, the findings may be useful for clinicians in providing anticipatory guidance. PMID:21932314

    Congenital heart disease (CHD) remains a significant health problem, with a growing population of survivors with chronic disease. Despite intense efforts to understand the genetic basis of CHD in humans, the etiology of most CHD is unknown. Furthermore, new models of CHD are required to better understand the development of CHD and to explore novel therapies for this patient population. In this review, we highlight the role that human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes can serve to enhance our understanding of the development, pathophysiology and potential therapeutic targets for CHD. We highlight the use of hiPSC-derived cardiomyocytes to model gene regulatory interactions, cell-cell interactions and tissue interactions contributing to CHD. We further emphasize the importance of using hiPSC-derived cardiomyocytes as personalized research models. The use of hiPSCs presents an unprecedented opportunity to generate disease-specific cellular models, investigate the underlying molecular mechanisms of disease and uncover new therapeutic targets for CHD.

    Despite animal studies having demonstrated that Tbx20 is essential for heart development, few studies have been conducted about TBX20 and congenital heart disease (CHD) in humans. Recently two TBX20 mutations have been associated with human heart defects in two Caucasian families, but TBX20 mutations underlying the more common isolated forms of CHD are still unknown. To explore this question and to analyze the association between TBX20 and susceptibility to CHD 203 Chinese patients with a variety of predominantly sporadic CHD and 300 control subjects were investigated for TBX20 mutations. The exon 2-6 contributing to the T-box DNA-binding domain and their flanking intron sequences were amplified by polymerase chain reaction (PCR) and then were sequenced after purification. Three non-synonymous mutations (A63T, I121F, and T262M) were identified in 3 patients, which were not seen in 300 controls. I121F and T262M mutations occurred within the highly conserved T-box DNA-binding domain. Two synonymous sequence variants (N222N, T262T) and one intervening variant (IVS2-5insCT) were observed in 3 patients but not in the controls. In addition, eight SNPs were observed both in patients and controls and four (S167S, P177P, A181A, and I219I) of them are novel. These data indicate that the frequency of TBX20 missense mutations occurred in Chinese CHD children is low, but they probably contribute to the risk of atrial septal defect (ASD), total anomalous pulmonary venous connection (TAPVC) and tetralogy of Fallot (TOF) in a small subset of Chinese. The findings provide the first insight into TBX20 mutations for TOF and TAPVC. Functional study involved in the new sequence variants should be subject of further investigation.

    Few previous studies have addressed exercise capacity in patients with corrected congenital heart disease (CHD) and significant anatomical residua. The aim of this study was to determine the aerobic fitness and peak cardiac function of patients with corrected CHD with complete or incomplete repairs, as determined by resting echocardiography. Children, adolescents and young adults (<40 years) with CHD from both sexes, who had previously undergone biventricular corrective therapeutic interventions (n = 73), and non-CHD control participants (n = 76) underwent cardiopulmonary exercise testing. The CHD group was further divided according to the absence/presence of significant anatomical residua on a resting echocardiogram ("complete"/"incomplete" repair groups). Aerobic fitness and cardiac function were compared between groups using linear regression and analysis of covariance. Peak oxygen consumption, O2 pulse and ventilatory threshold were significantly lower in CHD patients compared with controls (all p < 0.01). Compared with the complete repair group, the incomplete repair group had a significantly lower mean peak work rate, age-adjusted O2 pulse (expressed as % predicted) and a higher VE/VCO2 ratio (all p ≤ 0.05). Peak oxygen consumption was comparable between the subgroups. Patients after corrected CHD have lower peak and submaximal exercise parameters. Patients with incomplete repair of their heart defect had decreased aerobic fitness, with evidence of impaired peak cardiac function and lower pulmonary perfusion. Patients that had undergone a complete repair had decreased aerobic fitness attributed only to deconditioning. These newly identified differences explain why in previous studies, the lowest fitness was seen in patients with the most hemodynamically significant heart malformations.

    Congenital heart disease (CHD) is a complex illness with high rates of morbidity and mortality. In embryonic development, the heart is the first formed organ, which is strictly controlled by gene regulatory networks, including transcription factors, signaling pathways, epigenetic factors and microRNAs. Bone morphogenetic protein (BMP)-2 and -4 are essential in cardiogenesis as they can induce the expression of transcription factors, NKX2-5 and GATA binding protein 4, which are important in the development of the heart. The inhibition of BMP-2 and 4- inhibits the late expression of NKX2-5 and affects cardiac differentiation. The aim of the present study was to investigate whether BMP-2 and -4 variations may be associated with CHD in Chinese Han populations. The rs1049007, rs235768 and rs17563 single nucleotide polymorphisms (SNPs), which are genetic variations located within the translated region of the BMP-2 and -4, were evaluated in 230 patients with CHD from the Chinese Han population and 160 non CHD control individuals. Statistical analyses were performed using the χ2 test, implemented using SPSS software (version 13.0). The Hardy Weinberg equilibrium test was performed on the population using online Online Encyclopedia for Genetic Epidemiology studies software, and multiple-sequence alignments of the BMP proteins were performed using Vector NTI software. No statistically significant associations were identified between these genetic variations and the risk of CHD (rs1049007, P value=0.560; rs235768, P value=0.972; rs17563, P value=0.787). In addition, no correlation was found between the patients with CHD and the non-CHD control individuals. Therefore, the rs1049007, rs235768 and rs17563 genetic variations of BMP-2 were not associated with CHD in the Chinese Han population. PMID:27357418

    Determining safe levels of physical activity for children and adolescents with electrophysiologic and structural congenital heart disease is a challenging clinical problem. The body of evidence for making these recommendations is limited and likely based on expert opinion, medicolegal concerns, and perceived risks of sudden cardiac death (SCD) with activity. The Bethesda Conference has established consensus guidelines for determining the eligibility of athletes with cardiovascular abnormalities for competitive sports and their disqualification from them. However, literature on guidelines for noncompetitive physical activity is not available. A survey was designed to determine practice patterns for patients with electrophysiologic and structural congenital heart disease. Between July 2011 and December 2011, approximately 350 health care providers working with this group of patients were recruited by email or while attending professional meetings. The survey received 81 responses, primarily from pediatric cardiologists (70 %). The findings indicate that the majority of Canadian cardiac care providers surveyed are only partially implementing current recommendations. Areas of variance included physical activity recommendations for hypertrophic cardiomyopathy, long QT syndrome, catecholaminergic polymorphic ventricular tachycardia, and heart transplantation, among others. The development of comprehensive consensus guidelines for activity recommendations was supported by 96 % of the respondents. The heterogeneity of responses may be attributable to conflicting and poorly evidenced information in the literature, a lack of emphasis on recreational activity, an entrenched tendency toward bed rest in the cardiology community, and a lack of awareness by cardiac care providers regarding the actual risk associated with physical activity in electrophysiologic and structural congenital heart disease. A balanced discussion is required in considering both the significant benefit of

    Congenital heart malformations are the most common of all birth defects, affecting 0.5-1% of all live births. Some of these malformations are due to genetic anomalies. Patterns of autosomal dominant, autosomal recessive and X-linked inheritance have been described. Mitochondrial inheritance and chromosomal anomalies can also be responsible for congenital heart malformations. Several genes for congenital heart defects have been identified. We review current knowledge on the genetic etiology of congenital heart disease.

    Background High resolution melting (HRM) is a simple, flexible and low-cost mutation screening technique. The methylenetetrahydrofolate reductase (MTHFR) gene encoding a critical enzyme, potentially affects susceptibility to some congenital defects like congenital heart disease (CHD). We evaluate the performance of HRM for genotyping of the MTHFR gene C677T locus in CHD cases and healthy controls of Chinese Han population. Methods A total of 315 blood samples from 147 CHD patients (male72, female 75) and 168 healthy controls (male 92, female 76) were enrolled in the study. HRM was utilized to genotype MTHFR C677T locus of all the samples. The results were compared to that of PCR-RFLP and Sanger sequencing. The association of the MTHFR C677T genotypes and the risk of CHD was analyzed using odds ratio with their 95% confidence interval (CIs) from unconditional logistic regression. Results All the samples were successfully genotyped by HRM within 1 hour and 30 minutes while at least 6 hours were needed for PCR-RFLP and sequencing. The genotypes of MTHFR C677T CC, CT, and TT were 9.52%, 49.66%, and 40.82% in CHD group but 29.17%, 50% and 20.83% in control group, which were identical using both methods of HRM and PCR-RFLP, demonstrating the sensitivity and specificity of HRM were all 100%. Conclusion MTHFR C677T is a potential risk factor for CHD in our local residents of Shandong province in China. HRM is a fast, sensitive, specific and reliable method for clinical application of genotyping. PMID:26990189

    Congenital heart disease is associated with abnormal ventricular shape that can affect wall mechanics and may be predictive of long-term adverse outcomes. Atlas-based parametric shape analysis was used to analyze ventricular geometries of eight adolescent or adult single-ventricle CHD patients with tricuspid atresia and Fontans. These patients were compared with an "atlas" of non-congenital asymptomatic volunteers, resulting in a set of z-scores which quantify deviations from the control population distribution on a patient-by-patient basis. We examined the potential of these scores to: (1) quantify abnormalities of ventricular geometry in single ventricle physiologies relative to the normal population; (2) comprehensively quantify wall motion in CHD patients; and (3) identify possible relationships between ventricular shape and wall motion that may reflect underlying functional defects or remodeling in CHD patients. CHD ventricular geometries at end-diastole and end-systole were individually compared with statistical shape properties of an asymptomatic population from the Cardiac Atlas Project. Shape analysis-derived model properties, and myocardial wall motions between end-diastole and end-systole, were compared with physician observations of clinical functional parameters. Relationships between altered shape and altered function were evaluated via correlations between atlas-based shape and wall motion scores. Atlas-based shape analysis identified a diverse set of specific quantifiable abnormalities in ventricular geometry or myocardial wall motion in all subjects. Moreover, this initial cohort displayed significant relationships between specific shape abnormalities such as increased ventricular sphericity and functional defects in myocardial deformation, such as decreased long-axis wall motion. These findings suggest that atlas-based ventricular shape analysis may be a useful new tool in the management of patients with CHD who are at risk of impaired ventricular

    Background Advances in cardiac surgery and congenital cardiology have led to an increasing number of women with congenital heart disease (CHD) reaching childbearing age. In general, cardiologists recommend vaginal delivery for women with CHD to avoid complications from Caesarean section as many women with CHD tolerate vaginal delivery well. Methods and Results This is a single-center study comparing mode of delivery, pregnancy outcome, indications for Caesarean section and induction of labor between women with and without CHD. A historical cohort study was conducted including 116 patients with CHD. An individual threefold matching with 348 women without CHD was carried out. Caesarean section was performed in 46.6% of pregnancies with CHD (33.6% without CHD, P = 0.012). Primary Caesarean section increases with severity of CHD (P = 0.036), 33.3% of women with CHD had primary planned Caesarean section due to cardiac reasons. Induction of labor was performed in 45.7% of attempted vaginal deliveries in women with CHD (27.9% without CHD, P = 0.001). Lower mean birth weight (P = 0.004) and Small for Gestational Age (SGA) (P < 0.001) were more common in women with CHD. One CHD patient suffered from postpartum hemorrhage. Conclusions Concerns about maternal deterioration resulting in higher rates of induction of labor seem unjustified in most cases. Along with a possible reduction of Caesarean section on maternal request, a reduction of planned vaginal delivery may be expedient in reducing the rate of Caesarean section in women with CHD.

    Patients with severe pulmonary arterial hypertension suffer from life-threatening thrombotic and bleeding complications. The aim of this study was to compare selected platelet, endothelial, and coagulation parameters in healthy volunteers and patients with severe pulmonary arterial hypertension because of congenital heart defects. The study included healthy volunteers (n = 50) and patients with cyanotic congenital heart defects classified as Eisenmenger syndrome (n = 41). We investigated platelet count, mean platelet volume, and platelet aggregation - spontaneous and induced by various concentrations of five agonists. Von Willebrand factor (vWF), fibrinogen, factor VIII and XII, plasminogen activator inhibitor, antithrombin, D-dimer, and antiphospholipid antibodies were also investigated. We found a decreased platelet count [190 (147-225) vs. 248 (205-295) 10 l, P < 0.0001], higher mean platelet volume [10.9 (10.1-12.0) vs. 10.2 (9.4-10.4) fl, P < 0.0001], and significantly decreased platelet aggregation (induced by five agonists, in various concentrations) in patients with Eisenmenger syndrome compared with controls. These changes were accompanied by an increase of plasma vWF antigen [141.6 (108.9-179.1) vs. 117.4 (9.2-140.7) IU/dl, P = 0.022] and serum anti-β2-glycoprotein [2.07 (0.71-3.41) vs. 0.47 (0.18-0.99) U/ml, P < 0.0001]. Eisenmenger syndrome is accompanied by platelet abnormalities. Thrombocytopenia with increased platelet size is probably due to a higher platelet turnover associated with platelet activation. Impaired platelet aggregation can reflect specific platelet behaviour in patients with Eisenmenger syndrome. These changes can be related both to bleeding and to thrombotic events. A higher vWF antigen may be a consequence of endothelial damage in Eisenmenger syndrome, but the cause for an increase of anti-β2-glycoprotein is unknown.

    Deficiency in 25-hydroxyvitamin D (25OHD) is associated with increased morbidity and mortality in the critically ill. Children who underwent surgery for congenital heart disease under cardiopulmonary bypass (CPB) are typically deficient in 25OHD. It is unclear whether this deficiency is due to CPB. We hypothesized that CPB reduces the levels of 25OHD in children with congenital heart disease. We conducted a prospective observational study on children aged 2 months to 17 years who underwent CPB. Serum was collected at 3 time points: immediately before, immediately after surgery, and 24 hours after surgery. 25-Hydroxyvitamin D, 1,25-dihydroxyvitamin D, 1,25(OH)2D, vitamin D binding protein, and albumin levels were measured. Levels were compared using repeated measures analysis of variance. We enrolled 20 patients, 40% were deficient in 25OHD with levels <20 ng/mL prior to surgery. Mean (±standard deviation) of 25OHD at the 3 time points was 21.3 ± 8 ng/mL, 19 ± 5.8 ng/mL, and 19.5 ± 6.6 ng/mL, respectively (P = .02). The decrease in 25OHD was observed primarily in children with sufficient levels of 25OHD, with mean levels at the 3 time points: 26.8 ± 4.2 ng/mL, 21.5 ± 5.7 ng/mL, and 23.0 ± 4.9 ng/mL, respectively (P < .001). Calculated means of free fraction of 25OHD at the 3 time points were 6.2 ± 2.8 pg/mL, 5.8 ± 2.2 pg/mL, and 5.5 ± 2.4 pg/mL, respectively, (P = .04). Mean levels of 1,25(OH)2D were 63.7 ± 34.9 ng/mL, 53.2 ± 30.6 ng/mL, and 67.7 ± 23.5 ng/mL (P = .04). Vitamin D binding protein and albumin levels did not significantly change. Cardiopulmonary bypass decreases 25OHD by reducing the free fraction. Current investigations are geared to establish whether vitamin D deficiency is associated with outcomes and if treatment is appropriate.

    Diet, particularly vitamin deficiency, is associated with the risk of birth defects. The aim of this review paper is to show the characteristics of common and severe neural-tube defects together with congenital heart defects (CHD) as vitamin deficiencies play a role in their origin. The findings of the Hungarian intervention (randomized double-blind and cohort controlled) trials indicated that periconceptional folic acid (FA)-containing multivitamin supplementation prevented the major proportion (about 90%) of neural-tube defects (NTD) as well as a certain proportion (about 40%) of congenital heart defects. Finally the benefits and drawbacks of three main practical applications of folic acid/multivitamin treatment such as (i) dietary intake; (ii) periconceptional supplementation; and (iii) flour fortification are discussed. The conclusion arrived at is indeed confirmation of Benjamin Franklin's statement: "An ounce of prevention is better than a pound of care".

    Congenital heart disease (CHD) is extremely rarely reported in 48, XYY, +21 karyotype. Herein, we reported one case of 48,XYY,+21 karyotype with CHD and reviewed the available literature. The phenotypic characteristics of the 4-month-old child showed the presence of features typical of mongoloid slant. X-ray detection showed the form of heart was corpulent and the bilateral mediastinum was broad. Doppler echocardiogram detection showed atrial septal and ventricular septal defects with patent ductus arteriosus, pulmonary hypertension and mild tricuspid regurgitation. Including this case, 63 cases of 48, XYY, +21 chromosome pattern have been reported. However, only 9 cases have CHD.

    Objective Velo-cardio-facial syndrome (VCFS) is caused by a microdeletion of approximately 40 genes from one copy of chromosome 22. Expression of the syndrome is a variable combination of over 190 phenotypic characteristics. As of yet, little is known about how these phenotypes correlate with one another or whether there are predictable patterns of expression. Two of the most common phenotypic categories, congenital heart disease and cleft palate, have been proposed to have a common genetic relationship to the deleted T-box 1 gene (TBX1). The purpose of this study is to determine if congenital heart disease and cleft palate are correlated in a large cohort of human subjects with VCFS. Methods This study is a retrospective chart review including 316 Caucasian non-Hispanic subjects with FISH or CGH microarray confirmed chromosome 22q11.2 deletions. All subjects were evaluated by the interdisciplinary team at the Velo-Cardio-Facial Syndrome International Center at Upstate Medical University, Syracuse, NY. Each combination of congenital heart disease, cleft palates, and retrognathia was analyzed by chi square or Fisher exact test. Results For all categories of congenital heart disease and cleft palate or retrognathia no significant associations were found, with the exception of submucous cleft palate and retrognathia (nominal p=0.0325) and occult submucous cleft palate and retrognathia (nominal p=0.000013). Conclusions Congenital heart disease and cleft palate do not appear to be correlated in human subjects with VCFS despite earlier suggestions from animal models. Possible explanations include modification of the effect of TBX1 by genes outside of the 22q11.2 region that may further influence the formation of the palate or heart, or the presence of epigenetic factors that may effect genes within the deleted region, modifying genes elsewhere, or polymorphisms on the normal copy of chromosome 22. Lastly, it is possible that TBX1 plays a role in palate formation in some

    Successful outcome in the care of patients with congenital heart disease depends on a comprehensive multidisciplinary team. Surgery is offered for almost every heart defect, despite complexity. Early mortality for cardiac surgery in the neonatal period is ≈10% and beyond infancy is <5%, with 90% to 95% of patients surviving with a good quality of life into the adult years. Advances in imaging have facilitated accurate diagnosis and planning of interventions and surgical procedures. Similarly, advances in the perioperative medical management of patients, particularly with intensive care, has also contributed to improving outcomes. Arrhythmias and heart failure are the most common late complications for the majority of defects, and reoperation for valvar problems is common. Lifelong surveillance for monitoring of recurrent or residual structural heart defects, as well as periodic assessment of cardiac function and arrhythmia monitoring, is essential for all patients. The field of congenital heart surgery is poised to incorporate new innovations such as bioengineered cells and scaffolds that will iteratively move toward bioengineered patches, conduits, valves, and even whole organs.

    Serotonin reuptake inhibitors (SRIs) are often prescribed during pregnancy. Previous studies that found an increased risk of congenital anomalies, particularly congenital heart anomalies (CHA), with SRI use during pregnancy have created concern among pregnant women and healthcare professionals about the safety of these drugs. However, subsequent studies have reported conflicting results on the association between CHA and SRI use during pregnancy. These discrepancies in the risk estimates can potentially be explained by genetic differences among exposed individuals. In this review, we explore the potential pharmacogenetic predictors involved in the pharmacokinetics and mechanism of action of SRIs, and their relation to the risk of CHA. In general, the risk is dependent on the maternal concentration of SRIs and the foetal serotonin level/effect, which can be modulated by the alteration in the expression and/or function of the metabolic enzymes, transporter proteins and serotonin receptors involved in the serotonin signalling of the foetal heart development. Pharmacogenetics might be the key to understanding why some children exposed to SRIs develop a congenital heart anomaly and others do not. PMID:27529241

    Background Congenital heart disease (CHD) is the most prevalent type of birth defect in human, with high morbidity in infant. Several genes essential for heart development have been identified. GATA4 is a pivotal transcription factor that can regulate the cardiac development. Many GATA4 mutations have been identified in patients with different types of CHD. Aims In this study, the NKX2-5, HAND1 and GATA4 coding regions were sequenced in a family spanning three generations in which seven patients had CHD. Disease-causing potential variation in this family was evaluated by bioinformatics programs and the transcriptional activity of mutant protein was analyzed by the dual luciferase reporter assay. Results A novel GATA4 mutation, c.C931T (p.R311W), was identified and co-segregated with the affected patients in this family. The bioinformatics programs predicted this heterozygous mutation to be deleterious and the cross-species alignment of GATA4 sequences showed that the mutation occurred within a highly conserved amino acid. Even though it resided in the nuclear localization signal domain, the mutant protein didn’t alter its intracellular distribution. Nevertheless, further luciferase reporter assay demonstrated that the p.R311W mutation reduced the ability of GATA4 to activate its downstream target gene. Conclusions Our study identified a novel mutation in GATA4 that likely contributed to the CHD in this family. This finding expanded the spectrum of GATA4 mutations and underscored the pathogenic correlation between GATA4 mutations and CHD. PMID:27391137

    OBJECTIVE--To investigate the efficacy and safety of transcatheter laser-assisted valve dilatation for atretic valves in children with congenital heart disease. DESIGN--Prospective clinical study. SETTING--Supraregional paediatric cardiology centre. SUBJECTS--Eleven children (aged 1 day-11 years; weight 2.1-35.7 kg) with atresia of pulmonary (10) or tricuspid (one) valve underwent attempted laser-assisted valve dilatation as part of the staged treatment of their cyanotic heart disease. INTERVENTION--After delineating the atretic valve by angiography and/or echocardiography a 0.018 inch "hot tip" laser wire was used to perforate the atretic valve. Subsequently the valve was dilated with conventional balloon dilatation catheters up to the valve annulus diameter. RESULTS--Laser-assisted valve dilatation was successfully accomplished in nine children. In two neonates with pulmonary valve atresia, intact ventricular septum, and coexistent infundibular atresia the procedure resulted in cardiac tamponade: one died immediately and one later at surgery. During a follow up of 1-17 months (mean 11) two infants with pulmonary valve atresia and intact ventricular septum died (one with congestive cardiac failure). The remainder are either well palliated and do not require further procedures (three), or are awaiting further transcatheter or surgical procedures because of associated defects (four). CONCLUSIONS--Laser-assisted valve dilatation is a promising adjunct to surgery in this high risk group of patients. It may avoid surgery in some patients, and may reduce the number of surgical procedures in those requiring staged operations. Images PMID:8343325

    Objective Infants with congenital heart disease (CHD) receiving prostaglandins (PGE) may be at increased risk for necrotizing enterocolitis (NEC). Enteral feeding may further increase risk of NEC in these patients. We evaluated the incidence of NEC and its association with enteral feeding in infants with ductal-dependent CHD. Study Design We examined a cohort of infants with CHD receiving PGE in neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2010. We used logistic regression to evaluate the association between NEC and enteral feeding, as well as other risk factors including antacid medications, inotropic and ventilator support, and anatomic characteristics, controlling for gestational age. Results We identified 6710 infants with ductal-dependent CHD receiving PGE for 17,158 infant days. NEC occurred in 21 of 6710 (0.3%) infants, of whom 12/21(57%) were <37 weeks gestational age. The incidence of NEC was 1.2/1000 infant days while on enteral feeds versus 0.4/1000 infant days while not on enteral feeds (p=0.27). Enteral feeding was not associated with a statistically significant increased odds of NEC on the day of diagnosis (odds ratio [OR] 2.08; 95% confidence interval [CI] 0.38, 11.7). Risk factors associated with a significant increased odds of NEC included a diagnosis of single-ventricle heart defect (OR 2.82; 95% CI 1.23, 6.49), although the overall risk in this population remained low (8/1631, 0.5%). Conclusion The incidence of NEC in our cohort of infants with ductal-dependent CHD on PGE therapy was low and did not increase with enteral feeding. PMID:25486286

    About 1% of newborn presents some form of congenital heart disease (CHD). Eighty-five percent of these children, thanks to medical and surgical improvement, reaches adulthood. This open up new challenges in patients management, such as the evaluation and optimization of psychosocial functioning and quality of life of CHD subjects. The present review collects research literature regarding neurocognitive and psychopathological adjustment, and personality and quality of life of these patients, analyzing variables that may influence their development. Literature data lean towards a multifactorial process implied into an insufficient outcome of neurocognitive development in many patients. Psychopathological development seems "problematic" with the expression of behavioural disorders both externalising and internalising. But current researches don't consent univocal and definitive conclusions. The need for interventions to improve existential outcome for CHD subjects emerges: research on genetic factors and early recognition of at risk subjects must go with the necessity for research aiming to determine protective and risk factors related to personality, environment and relational aspects entailed in the development of CHD subjects. Finally, some evidences noticed in CHD subjects psychopathological and quality of life outcomes which are even better than normal ones. These results depend on the elaboration of their disease that CHD subjects have carried on. Factors regarding mainly personality development are essential in determining these outcomes.

    Thank to medical and surgical improvements, a very high percentage of children with congenital heart disease (CHD; about 1% of newborn) reaches adulthood. This population of young surgical and medical patients opens up new challenges in clinical management, including evaluation and optimization of psychosocial functioning and quality of life. Data regarding neurocognitive and psychopathological adaptation, personality and quality of life of CHD patients are rather extensive but still insufficient to guide management approaches to these subjects and to address the numerous emerging problems. The present review analyzes extensively the research literature to find out those variables that may influence development of CHD children. It emerges that a multi-factorial process seems involved in the poor outcome of neurocognitive development in many patients. Notwithstanding the attempts to define risk factors, current researches do not consent definitive conclusions about the determinants of developmental problems in CHD children. An improvement of existential outcome for CHD subjects may be achieved if adequate interventions are carried out. In fact, psychopathological and quality of life in CHD subjects may result even better if elaboration of disease by CHD subjects is adequately supported. On one hand, genetic factors that may contribute to unfavourable evolutions suggest the need for early recognition of subjects at risk. On the other, research should be addressed to the identification of those protective and risk factors related to personality, environmental and relational aspects entailed in the development of CHD subjects.

    The perspective of the integrated health system has a network of care with multiple integration dimensions among subsystems as nuclear representation, relating the clinical aspects and governance to the representations and collective values. The normative integration aims to ensure coherence between the system of representations and values of society simultaneously with the interfaces of clinical and functional integration. It builds a bridge with governance, which allows, through their skills, management of all system components, encouraging cooperation, communication and information, in order to ensure the population under their responsibility to access excellence services, exceeding their expectations. The integration of care consists of a durable coordination of clinical practices for those who suffer from health problems in order to ensure continuity and full range of the required professional services and organizations, coordinated in time and space, in accordance with the available knowledge. It is possible to establish the type of health equipment for each level of care for patients with congenital heart diseases. This strategy intends to offer timely care in appropriate moments and places, efficiently, operating cooperatively an interdependently, with ongoing exchange of its resources. Thus, situational integration establishes the system connection with the assessment environment that proposes to carry out value judgment, guided by an objective worldview, about an intervention or any of its components, in order to objectify the decision making.

    Since the early 1980s prenatal diagnosis of congenital heart disease (CHD) has progressively impacted on the practice of pediatric cardiology and cardiac surgery. Fetal cardiology today raises special needs in screening programs, training of the involved staff, and allocations of services. Due to the increased detection rate and to the substantial number of terminations, the reduced incidence of CHD at birth can affect the workload of centers of pediatric cardiology and surgery. In utero transportation and competition among centers may change the area of referral in favor of the best centers. Echocardiography is a powerful means to diagnose and to guide lifesaving medical treatment of sustained tachyarrhythmias in the fetus. Prenatal diagnosis not only improves the preoperative conditions in most cases but also postoperative morbidity and mortality in selected types of CHD. Intrauterine transcatheter valvuloplasty in severe outflow obstructive lesions has been disappointing so far and this technique remains investigational, until its benefits are determined by controlled trials. Prenatal diagnosis allows counselling of families which are better prepared for the foreseeable management and outcome of the fetus. These benefits can reduce the risks of litigation for missed ultrasound diagnosis. As increased costs can be expected in institutions dealing with a large number of fetal CHD, the administrators of these institutions should receive protected funds, proportional to their needs.

    Congenital heart defect (CHD) is common in infants with Down syndrome (DS), which is the principle cause of mortality. However, there is no data available for the frequency and types of CHD in infants with DS in Korea. We investigated the frequency of CHD in infants with DS in Korea. After the survey on birth defects was conducted throughout the country, the prevalence of CHD in DS in 2005-2006 was calculated. This study was conducted based on the medical insurance claims database of the National Health Insurance Corporation. The number of total births in Korea was 888,263 in 2005-2006; of them, 25,975 cases of birth defects were identified. The prevalence of DS was 4.4 per 10,000 total births, accounting for 1.5% of all birth defects. Of the 394 infants with DS, 224 (56.9%) had a CHD. Atrial septal defect was the most common defect accounting for 30.5% of DS followed by ventricular septal defect (19.3%), patent duct arteriosus (17.5%), and atrioventricular septal defect (9.4%). Our study will be helpful to demonstrate the current status of DS and to identify the distribution of CHD in infants with DS in Korea.

    Non-invasive testing of children with congenital heart disease (CHD) began in the 1950s with the introduction of radionuclide studies to assess shunt fractions, pulmonary blood flow, and ventricular contractile function. Echocardiography and cardiac magnetic resonance imaging have since replaced radionuclide imaging in many of these roles. Concurrently, percutaneous and surgical repairs of complex CHD evolved, creating new roles for radionuclide imaging. In this paper on applications of radionuclide imaging in CHD, we review the multiple mechanisms for myocardial ischemia in CHD. We critically compare optimal radionuclide imaging techniques to other imaging modalities for assessing ischemia in CHD. We present the current role of nuclear imaging for assessing viability and pulmonary blood flow. We highlight the value added by advances in dedicated cardiac SPECT scanners, novel reconstruction software, and cardiac PET in performing low-dose radionuclide imaging in CHD. Finally, we discuss the emerging clinical indications for radionuclide imaging in CHD including coronary flow reserve assessment and evaluation of cardiovascular prosthesis and device infections.

    In children with congenital cyanotic heart disease, right-to-left intracardiac shunting causes an obligatory difference between arterial and end-tidal carbon dioxide tension (PaCO2-PE'CO2) as venous blood, rich in carbon dioxide, is added to the arterial circulation. This obligatory PaCO2-PE'CO2 difference, which can be predicted from knowledge of oxygen saturation, haemoglobin concentration and PaCO2, increases as oxygen saturation decreases, most markedly when the haemoglobin concentration is high. A second possible cause of the PaCO2-PE'CO2 difference is the effect of pulmonary hypoperfusion caused by the shunt. We studied 60 children undergoing cardiac surgery and compared the predicted the PaCO2-PE'CO2 difference with measured values to investigate the extent to which additional factors influence the clinically observed PaCO2-PE'CO2. In many children, observed values were much greater than predicted, which is compatible with some degree of pulmonary hypoperfusion. However, this was not felt to represent the complete picture in all patients. Another cause of ventilation-perfusion mismatch was suspected in those children who showed a considerable improvement in oxygen saturation during ventilation with an increased FIO2. We believe that pulmonary congestion caused by large left-to-right shunts may further increase the PaCO2-PE'CO2 difference.

    Hair arsenic and cadmium from 339 women with congenital heart defect (CHD)-affected pregnancies (case women) and 333 women with normal live births (control women) in China were estimated using inductively coupled plasma mass spectrometry. The median levels of hair arsenic and cadmium in the case women were 98.30 (74.30-136.30)ng/g and 14.60 (8.30-32.50)ng/g, respectively, which were significantly higher than the levels in the control group (P<0.05). Arsenic concentrations ≥62.03ng/g were associated with increased risk for almost every CHD subtype, with a dose-response relationship. However, only the group with the highest cadmium levels (≥25.85ng/g) displayed an increased risk of CHDs (AOR 1.96; 95% CI 1.24-3.09), with a 2.81-fold increase found for the occurrence of conotruncal defects in their offspring. Furthermore, an interaction between arsenic and cadmium was observed. Our findings suggest that maternal exposure to arsenic and cadmium may be a significant risk factor for CHDs in offspring. Cadmium may have an enhancing effect on the association between arsenic and the risk of CHDs in offspring.

    Biopsy specimens of the thymus were studied in children aged under 11 months (n = 77) with congenital heart defects and circulatory hypoxia of varying severity. Histological sections were stained with hematoxylin-eosin and Shubich's method (to demonstrate mast cells). The expression of Ki-67, CD3 and CD34 was assessed by immunohistochemistry. The ultrastructure of thymic tissues was also examined. It was found that the severity of hypoxia determined the morphological changes in the organ associated with a development of large complex of tissue reactions. A disruption of internal structure and a loss of integrity of epithelio-reticular cells and thymocytes were demonstrated in ultrathin sections. Thymocyte proliferation index (Ki-67) and thymocytopoiesis intensity (CD3+) were reduced in all the zones of the thymus. The degree of hypoxia affected the redistribution of CD3+ lymphocytes leading to their accumulation in the medulla. The processes of endogenous regeneration took place which involved the cells of fibroblastic line and progenitor cells (CD34+) together with active formation of new blood vessels. These findings suggest that the morphological changes identified in the tissues of the thymus are a manifestation of tissue adaptation to hypoxia of varying severity under conditions of endogenous regeneration, simultaneously reflecting the processes of substitution cytogenesis.

    Single ventricle congenital heart defects, which are characterized by cyanotic mixing between the oxygenated and de-oxygenated blood, afflict 2 per every 1000 live births. These defects are surgically treated by connecting the superior and inferior vena cava to the pulmonary arteries. However, such a configuration (also known as the total cavopulmonary connection), results in high energy losses and therefore the optimization of this connection prior to the surgery could significantly improve post-operative performance. In this paper, a surgical planning framework is proposed. It is exemplified on a patient with pre and post surgical MRI data. A pediatric surgeon performed a "virtual surgery" on the reconstruction of the patient's anatomy prior to the actual surgery. Post-operative hemodynamics in the virtually designed post-surgical anatomy and in the actual one are computed using computational fluid dynamics and compared to each other. This framework provides the surgeon to envision numerous scenarios of possible surgical options, and accordingly predict the post operative hemodynamics.

    Critical congenital heart disease (CCHD) screening is effective in asymptomatic late preterm and term newborn infants with a low false positive rate (0.035%). Objective (1) To compare 2817 NICU discharges before and after implementation of CCHD screening; and (2) to evaluate CCHD screening at < 35 weeks gestation. Methods collection of results of CCHD screening including preductal and postductal SpO2 values. Results During the pre-CCHD screen period, 1247 infants were discharged from the NICU and one case of CCHD was missed. After 3/1/12, 1508 CCHD screens were performed among 1570 discharges and no CCHDs were missed. The preductal and postductal SpO2 values were 98.8±1.4% and 99±1.3% respectively in preterm and 98.9±1.3% and 98.9±1.4% in term infants. Ten infants had false positive screens (10/1508=0.66%). Conclusions Performing universal screening in the NICU is feasible but is associated with a higher false positive rate compared to asymptomatic newborn infants. PMID:25058746

    The success of cardiac surgery over the past 50 years has increased numbers and median age of survivors with congenital heart disease (CHD). Adults now represent two-thirds of patients with CHD; in the United States alone the number is estimated to exceed 1 million.In this population many affected women reach reproductive age and wish to have children. While in many CHD patients pregnancy can be accomplished successfully, some special situations with complex anatomy, iatrogenic or residual pathology are associated with an increased risk of severe maternal and fetal complications. Pre-conception counseling allows women to come to truly informed choices. Risk stratification tools can also help high-risk women to eventually renounce to pregnancy and to adopt safe contraception options. Once pregnant, women identified as intermediate or high-risk should receive multidisciplinary care involving a cardiologist, an obstetrician and an anesthesiologist with specific expertise in managing this peculiar medical challenge.This document is intended to provide cardiologists working in hospitals where an Obstetrics and Gynecology Department is available with a streamlined and practical tool, useful for them to select the best management strategies to deal with a woman affected by CHD who desires to plan pregnancy or is already pregnant.

    Congenital heart defects (CHDs) have a neonatal incidence of 0.8-1% (refs. 1,2). Despite abundant examples of monogenic CHD in humans and mice, CHD has a low absolute sibling recurrence risk (∼2.7%), suggesting a considerable role for de novo mutations (DNMs) and/or incomplete penetrance. De novo protein-truncating variants (PTVs) have been shown to be enriched among the 10% of 'syndromic' patients with extra-cardiac manifestations. We exome sequenced 1,891 probands, including both syndromic CHD (S-CHD, n = 610) and nonsyndromic CHD (NS-CHD, n = 1,281). In S-CHD, we confirmed a significant enrichment of de novo PTVs but not inherited PTVs in known CHD-associated genes, consistent with recent findings. Conversely, in NS-CHD we observed significant enrichment of PTVs inherited from unaffected parents in CHD-associated genes. We identified three genome-wide significant S-CHD disorders caused by DNMs in CHD4, CDK13 and PRKD1. Our study finds evidence for distinct genetic architectures underlying the low sibling recurrence risk in S-CHD and NS-CHD.

    We estimated the longer-term cost-effectiveness of using telemedicine screening for prenatal detection of congenital heart disease (CHD). One hospital in south-east England with a telemedicine service was connected to a fetal cardiology unit in London. A UK health service perspective was adopted. Evidence on costs and outcomes for standard-risk pregnant women during the antenatal period was based on patient-level data. Extrapolation beyond the end of the study (just after delivery) was carried out for the lifetime of children born with and without CHD. Expert opinion and data from published sources was used to populate a decision model. Future costs and benefits were discounted. The main outcome was quality-adjusted life years (QALYs) and results were expressed as cost per QALY gained. Various one-way sensitivity analyses were conducted. The model showed that offering telemedicine screening by specialists to all standard-risk pregnant women was the dominant strategy (i.e. cheaper and more effective). The sensitivity analyses found that the model was robust, and that telemedicine remained the most cost-effective strategy. The study showed that it would be cost-effective to provide telemedicine examinations as part of an antenatal screening programme for all standard-risk women.

    The perspective of the integrated health system has a network of care with multiple integration dimensions among subsystems as nuclear representation, relating the clinical aspects and governance to the representations and collective values. The normative integration aims to ensure coherence between the system of representations and values of society simultaneously with the interfaces of clinical and functional integration. It builds a bridge with governance, which allows, through their skills, management of all system components, encouraging cooperation, communication and information, in order to ensure the population under their responsibility to access excellence services, exceeding their expectations. The integration of care consists of a durable coordination of clinical practices for those who suffer from health problems in order to ensure continuity and full range of the required professional services and organizations, coordinated in time and space, in accordance with the available knowledge. It is possible to establish the type of health equipment for each level of care for patients with congenital heart diseases. This strategy intends to offer timely care in appropriate moments and places, efficiently, operating cooperatively an interdependently, with ongoing exchange of its resources. Thus, situational integration establishes the system connection with the assessment environment that proposes to carry out value judgment, guided by an objective worldview, about an intervention or any of its components, in order to objectify the decision making.

    Down syndrome (DS), caused by trisomy of human chromosome 21 (Hsa21), is the most common cause of congenital heart defects (CHD), yet the genetic and mechanistic causes of these defects remain unknown. To identify dosage-sensitive genes that cause DS phenotypes, including CHD, we used chromosome engineering to generate a mapping panel of 7 mouse strains with partial trisomies of regions of mouse chromosome 16 orthologous to Hsa21. Using high-resolution episcopic microscopy and three-dimensional modeling we show that these strains accurately model DS CHD. Systematic analysis of the 7 strains identified a minimal critical region sufficient to cause CHD when present in 3 copies, and showed that it contained at least two dosage-sensitive loci. Furthermore, two of these new strains model a specific subtype of atrio-ventricular septal defects with exclusive ventricular shunting and demonstrate that, contrary to current hypotheses, these CHD are not due to failure in formation of the dorsal mesenchymal protrusion.

    BACKGROUND: In patients with congenital heart disease undergoing cardiac catheterization for hemodynamic purposes, parameter estimation by the indirect Fick method using a single predicted value of oxygen consumption has been a matter of criticism. OBJECTIVE: We developed a computer-based routine for rapid estimation of replicate hemodynamic parameters using multiple predicted values of oxygen consumption. MATERIALS AND METHODS: Using Microsoft® Excel facilities, we constructed a matrix containing 5 models (equations) for prediction of oxygen consumption, and all additional formulas needed to obtain replicate estimates of hemodynamic parameters. RESULTS: By entering data from 65 patients with ventricular septal defects, aged 1 month to 8 years, it was possible to obtain multiple predictions for oxygen consumption, with clear between-age groups (P <.001) and between-methods (P <.001) differences. Using these predictions in the individual patient, it was possible to obtain the upper and lower limits of a likely range for any given parameter, which made estimation more realistic. CONCLUSION: The organized matrix allows for rapid obtainment of replicate parameter estimates, without error due to exhaustive calculations. PMID:19641642

    The presence of pulmonary arterial hypertension (PAH) increases morbidity and reduces survival in patients with congenital heart disease (CHD). PAH-CHD is a heterogeneous condition, depending on the type of the underlying defect and previous repair strategies. There is growing evidence of the benefits of PAH-specific therapy in the PAH-CHD population, but despite recent advances mortality rates remain relatively high. In the last years, an increasing focus has been placed on patients with PAH-CHD and net left-to-right shunt. Currently, there are limited data to guide the management of these patients and uncertainty on the cut-off values for eventual defect closure. Pregnancy conveys significant risks in PAH-CHD patients: appropriate counselling and care, including psychological support and a multidisciplinary team, should be part of the routine management of women with PAH-CHD of reproductive age. Some subgroups, such as patients with Down's syndrome, Fontan circulation and 'segmental' pulmonary hypertension, present particular challenges in terms of management and therapy. The current review focuses on contemporary treatment strategies in PAH-CHD patients with particular emphasis on challenging patient groups and conditions.

    Computational models of congenital heart disease (CHD) have become increasingly sophisticated over the last 20 years. They can provide an insight into complex flow phenomena, allow for testing devices into patient-specific anatomies (pre-CHD or post-CHD repair) and generate predictive data. This has been applied to different CHD scenarios, including patients with single ventricle, tetralogy of Fallot, aortic coarctation and transposition of the great arteries. Patient-specific simulations have been shown to be informative for preprocedural planning in complex cases, allowing for virtual stent deployment. Novel techniques such as statistical shape modelling can further aid in the morphological assessment of CHD, risk stratification of patients and possible identification of new ‘shape biomarkers’. Cardiovascular statistical shape models can provide valuable insights into phenomena such as ventricular growth in tetralogy of Fallot, or morphological aortic arch differences in repaired coarctation. In a constant move towards more realistic simulations, models can also account for multiscale phenomena (eg, thrombus formation) and importantly include measures of uncertainty (ie, CIs around simulation results). While their potential to aid understanding of CHD, surgical/procedural decision-making and personalisation of treatments is undeniable, important elements are still lacking prior to clinical translation of computational models in the field of CHD, that is, large validation studies, cost-effectiveness evaluation and establishing possible improvements in patient outcomes.

    Congenital heart disease (CHD) is the most common form of birth defect and is the leading noninfectious cause of infant death. A growing body of evidence demonstrates that genetic risk factors are involved in the pathogenesis of CHD. However, CHD is a genetically heterogeneous disease and the genetic defects underlying CHD in an overwhelming majority of patients remain unclear. In this study, the whole coding region and splice junction sites of the PITX2c gene, which encodes variant 3 of paired-like homeodomain transcription factor 2 crucial for normal cardiovascular morphogenesis, were sequenced in 382 unrelated patients with CHD, and 2 novel heterozygous mutations, p.W147X and p.N153D, were identified in 2 unrelated patients with CHD, respectively, including a 1-year-old male patient with double outlet right ventricle in combination with ventricular septal defect and a 4-year-old female patient with ventricular septal defect. The mutations were absent in 400 control chromosomes and were both predicted to be disease-causing by MutationTaster. Multiple alignments of PITX2c proteins across species displayed that the altered amino acids were completely conserved evolutionarily. Functional analysis revealed that the mutated PITX2c proteins were associated with a significantly reduced transactivational activity compared with their wild-type counterpart. These findings provide a novel insight into the molecular mechanisms implicated in CHD, suggesting potential implications for the antenatal prophylaxis and allele-specific treatment of CHD.

    Congenital heart disease (CCHD) is the most common birth defect. Screening for the most critical forms (CCHD) using pulse oximetry was added to the Recommended Uniform Screening Panel in the United States in 2011. Since then, CCHD screening has become nearly universal in the United States. Nurses are ideally situated to contribute to the development of best practices for implementation and provide education to families on CCHD screening. Much of the standardization, advocacy, and development of national recommendations occurred with key input from nurses. Nurses often have responsibility for educating parents, performing the screening, interpreting the screening algorithm, and the documentation of results. The nurse role often includes implementing follow-up quality improvement initiatives to ensure that systematic and accurate screening occurs. Smooth implementation can be achieved by identifying champions early, obtaining input from a multidisciplinary team including both physician and nursing leaders, and identifying ways to integrate screening into already existing workflow. By knowing the basics of why screening is important, how to screen, current recommendations on the follow-up for positive screens and the limitations of CCHD screening, nurses can advocate for their patients and positively impact outcomes for infants born with CCHD through early identification before discharge.

    Improved surgical and medical therapy have prolonged survival in patients with congenital heart disease (CHD) such that general medical conditions like coronary artery disease (CAD) are now the main determinants of mortality. A summary of the association of CAD with CHD, as well as a discussion of the radiologic evaluation of the coronary arteries in adults with CHD is described herein. Cross sectional imaging to evaluate CAD in adults with CHD should follow the same appropriateness criteria as gender and aged matched patients without CHD. Coronary CT imaging may be particularly valuable in evaluating the coronary arteries in this patient population as invasive coronary angiography may prove challenging secondary to complicated or unconventional anatomy of the coronary arteries. Further, typical methods for evaluating CAD such as stress or echocardiography may be impractical in adults with CHD. Finally, delineating the anatomic relationship of the coronary arteries and their relationship with the sternum, chest wall, conduits, grafts, and valves is highly recommended in patients with CHD prior to reintervention to avoid iatrogenic complications.

    It is widely recognised that children with congenital heart disease (CHD) are at high risk for neurodevelopmental impairments including attention deficit hyperactivity disorder and autism spectrum disorder symptoms. Executive function impairments are one of the most prominent neurodevelopmental features associated with CHD. These deficits can have widespread debilitating repercussions in children's neurocognitive, behavioural, and psycho-social development. There is a crucial gap in research regarding the efficacy of preventive or treatment strategies for these important cognitive morbidities. Executive functions are complex neurocognitive skills highly amenable to improvement. Evidence-based interventions have shown promising results in other paediatric populations, strongly suggesting that they might also benefit the growing population of children with CHD. In this review, we summarise the available data on executive function impairments in children and adolescents with CHD. We underline the important co-morbidity of executive dysfunction with other cognitive and psychiatric issues in CHD, which raises awareness of the crucial need to prevent or at least mitigate these deficits. Finally, we summarise future avenues for research in terms of interventions that may help reduce executive function impairments in youth with CHD.

    Objectives. We examined the association between survival of infants with severe congenital heart defects (CHDs) and community-level indicators of socioeconomic status. Methods. We identified infants born to residents of Arizona, New Jersey, New York, and Texas between 1999 and 2007 with selected CHDs from 4 population-based, statewide birth defect surveillance programs. We linked data to the 2000 US Census to obtain 11 census tract–level socioeconomic indicators. We estimated survival probabilities and hazard ratios adjusted for individual characteristics. Results. We observed differences in infant survival for 8 community socioeconomic indicators (P < .05). The greatest mortality risk was associated with residing in communities in the most disadvantaged deciles for poverty (adjusted hazard ratio [AHR] = 1.49; 95% confidence interval [CI]  = 1.11, 1.99), education (AHR = 1.51; 95% CI = 1.16, 1.96), and operator or laborer occupations (AHR = 1.54; 95% CI = 1.16, 1.96). Survival decreased with increasing numbers of indicators that were in the most disadvantaged decile. Community-level mortality risk persisted when we adjusted for individual-level characteristics. Conclusions. The increased mortality risk among infants with CHDs living in socioeconomically deprived communities might indicate barriers to quality and timely care at which public health interventions might be targeted.

    Pulmonary arterial hypertension associated with congenital heart disease (CHD-PAH) has serious consequence and plasma protein profiles in CHD-PAH are unknown. We aimed to reveal the differential plasma proteins in 272 CHD patients with or without PAH. Various types of CHD-PAH were studied. Differential plasma proteins were first detected by iTRAQ proteomic technology and those with significant clinical relevance were selected for further ELISA validation in new cohort of patients. Among the 190 differential plasma proteins detected by iTRAQ, carbamoyl-phosphate synthetase I (CPSI, related to urea cycle and endogenous nitric oxide production) and complement factor H-related protein 2 (CFHR2, related to complement system and coagulant mechanism) were selected for further ELISA validation in new cohort of 152 patients. Both CPSI and CFHR2 were down-regulated with decreased plasma levels (p < 0.01). Thus, we for the first time in CHD-PAH patients identified a large number of differential plasma proteins. The decreased CPSI expression in CHD-PAH patients may reveal a mechanism related to endogenous nitric oxide and the decrease of CFHR2 protein may demonstrate the deficiency of the immune system and coagulation mechanism. The findings may open a new direction for translational medicine in CHD-PAH with regard to the diagnosis and progress of the disease.

    Pulmonary arterial hypertension (PAH) is an uncommon but serious disease characterized by severe pulmonary vascular disease and significant morbidity and mortality. PAH associated with congenital heart disease (APAH-CHD) is one etiology of PAH that has innate characteristics delineating it from other forms of PAH. The patient with APAH-CHD presents with unique challenges consisting of not only pulmonary vascular disease but also the complexity of the cardiac lesion. Eisenmenger syndrome (ES) represents the severe end of the spectrum for disease in APAH-CHD. Over time, systemic-to-pulmonary shunting through cardiac defects increases pulmonary vascular resistance to levels significant enough to reverse shunting across the defect. Historically, ES patients have been reported to have better outcomes than IPAH despite similarities in pulmonary vascular disease. However, recent studies are challenging this notion. Nonetheless, APAH-CHD survival has improved with the advent of modern PAH targeted therapies. New therapeutic options have allowed us to reconsider the dogma of inoperability in APAH-CHD patients with unrepaired defects. Certainly advances have been made, however, investigators must continue to advance the field through controlled clinical trials in both adult and pediatric APAH-CHD patients. PMID:25604592

    The objective of this study was to evaluate whether high levels of maternal exposure to O3, SO2, NO2, CO are related to increased risk of congenital heart defects (CHDs) in Wuhan, China. The study included mothers living in the central districts of Wuhan during pregnancy over the two-year period from June 10, 2011 to June 9, 2013. For each study participant, we assigned 1-month averages of O3, SO2, NO2 and CO exposure based on measurements obtained from the nearest exposure monitor to the living residence of mothers during their early pregnancy period. In one-pollutant model, we observed an increased risk of CHDs, ventricular septal defect (VSD), and tetralogy of fallot (TF) with increasing O3 exposure. In two-pollutant model, associations with all CHDs, VSD, and TF for O3 were generally consistent compared to the models that included only O3, with the strongest aORs observed for exposures during the third month of pregnancy. We also observed a positive association between CO exposures during the third month of pregnancy and VSD in two pollution model.Our results contribute to the small body of evidence regarding air pollution exposure and CHDs, but confirmation of these associations will be needed in future studies.

    During the last decades, advances in diagnosis and treatment of congenital heart disease have allowed many individuals to reach adulthood. Due mainly to the great diagnostic diversity and to the co-morbidities usually present in this age group, these patients demand assistance in a multidisciplinary facility if an adequate attention is aimed. In this paper we reviewed, based in the international literature and also on the authors’ experience, the structural conditions that should be available for these patients. We highlighted aspects like the facility characteristics, the criteria usually adopted for patient transfer from the paediatric setting, the composition of the medical and para- medical staff taking into account the specific problems, and also the model of outpatient and in-hospital assistance. We also emphasized the importance of patient data storage, the fundamental necessity of institutional support and also the compromise to offer professional training. The crucial relevance of clinical research is also approached, particularly the development of multicenter studies as an appropriate methodology for this heterogeneous patient population.

    Congenital heart diseases (CHD) represent the most common birth defect in human. The majority of cases are caused by a combination of complex genetic alterations and environmental influences. In the past, many disease-causing mutations have been identified; however, there is still a large proportion of cardiac malformations with unknown precise origin. High-throughput sequencing technologies established during the last years offer novel opportunities to further study the genetic background underlying the disease. In this review, we provide a roadmap for designing and analyzing high-throughput sequencing studies focused on CHD, but also with general applicability to other complex diseases. The three main next-generation sequencing (NGS) platforms including their particular advantages and disadvantages are presented. To identify potentially disease-related genomic variations and genes, different filtering steps and gene prioritization strategies are discussed. In addition, available control datasets based on NGS are summarized. Finally, we provide an overview of current studies already using NGS technologies and showing that these techniques will help to further unravel the complex genetics underlying CHD.

    Complex congenital heart disease (CHD) affects cardiac blood flow, generating a pressure overload in the compromised ventricles and provoking hypertrophy that over time will induce myocardial dysfunction and cause a potential risk of imminent death. Therefore, the early diagnosis of complex CHD is paramount during the first year of life, with surgical treatment of patients favoring survival. In the present study, we analyzed cardiac tissue and plasma of children with cardiac hypertrophy (CH) secondary to CHD for the expression of 11 miRNAs specific to CH in adults. The results were compared with the miRNA expression patterns in tissue and blood of healthy children. In this way, we determined that miRNAs 1, 18b, 21, 23b, 133a, 195, and 208b constitute the expression profile of the cardiac tissue of children with CHD. Meanwhile, miRNAs 21, 23a, 23b, and 24 can be considered specific biomarkers for the diagnosis of CH in infants with CHD. These results suggest that CH secondary to CHD in children differs in its mechanism from that described for adult hypertrophy, offering a new perspective to study the development of this pathology and to determine the potential of hypertrophic miRNAs to be biomarkers for early CH.

    Intravascular or intracardiac stenoses occur in many forms of congenital heart disease (CHD). Therefore, the implantation of stents has become an accepted interventional procedure for stenotic lesions in pediatric cardiology. Furthermore, stents are know to be used to exclude vessel aneurysm or to ensure patency of existing or newly created intracardiac communications. With the further refinement of the first generation of devices, a variety of “modern” stents with different design characteristics have evolved. Despite the tremendous technical improvement over the last 20 years, the “ideal stent” has not yet been developed. Therefore, the pediatric interventionalist has to decide which stent is suitable for each lesion. On this basis, currently available stents are discussed in regard to their advantages and disadvantages for common application in CHD. New concepts and designs developed to overcome some of the existing problems, like the failure of adaptation to somatic growth, are presented. Thus, in the future, biodegradable or growth stents might replace the currently used generation of stents. This might truly lead to widening indications for the use of stents in the treatment of CHD.

    Purpose. Congenital heart disease (CHD) is reported to be associated with Hirschsprung disease (HD). The aim was to evaluate any differences between children with HD with and without CHD, respectively, with regard to patient characteristics, medical care, and patient reported bowel function. Method. This is a retrospective chart study and a cross-sectional long-term follow-up of patients older than 4 years old, including all children with HD operated on with transanal endorectal pull-through (TERPT) at a tertiary center of pediatric surgery. Information about patient characteristics, diagnostics, surgery, and medical care was compiled. At long-term follow-up, bowel function was assessed by Bowel Function Score. Results. Included were 53 HD-patients, 13 with CHD and 40 without CHD. Children with CHD more commonly presented with failure to thrive; 4 (23%) compared to those without CHD (0%) (p < 0.01). In the long-term follow-up, including 32 patients (6 with CHD), constipation was more commonly reported by children with CHD 5 (83%) than by children without CHD 4 (27%) (p = 0.01). No differences were shown in the other parameters such as fecal control and incontinence. Conclusion. HD-patients with CHD more commonly presented with failure to thrive and more frequently reported constipation than HD-patients without CHD. The findings indicate that HD-patients with CHD might need special consideration in their initial care and long-term follow-up. PMID:28373976

    Background: Previous studies have yielded inconsistent results for the effects of periconceptional multivitamins containing folic acid and of folic acid food fortification on congenital heart defects (CHDs). Methods: We carried out a population-based cohort study (N=5 901 701) of all live births and stillbirths (including late-pregnancy terminations) delivered at ≥20 weeks’ gestation in Canada (except Québec and Manitoba) from 1990 to 2011. CHD cases were diagnosed at birth and in infancy (n=72 591). We compared prevalence rates and temporal trends in CHD subtypes before and after 1998 (the year that fortification was mandated). An ecological study based on 22 calendar years, 14 geographic areas, and Poisson regression analysis was used to quantify the effect of folic acid food fortification on nonchromosomal CHD subtypes (n=66 980) after controlling for changes in maternal age, prepregnancy diabetes mellitus, preterm preeclampsia, multiple birth, and termination of pregnancy. Results: The overall birth prevalence rate of CHDs was 12.3 per 1000 total births. Rates of most CHD subtypes decreased between 1990 and 2011 except for atrial septal defects, which increased significantly. Folic acid food fortification was associated with lower rates of conotruncal defects (adjusted rate ratio [aRR], 0.73, 95% confidence interval [CI], 0.62–0.85), coarctation of the aorta (aRR, 0.77; 95% CI, 0.61–0.96), ventricular septal defects (aRR, 0.85; 95% CI, 0.75–0.96), and atrial septal defects (aRR, 0.82; 95% CI, 0.69–0.95) but not severe nonconotruncal heart defects (aRR, 0.81; 95% CI, 0.65–1.03) and other heart or circulatory system abnormalities (aRR, 0.98; 95% CI, 0.89–1.11). ConclusionS: The association between food fortification with folic acid and a reduction in the birth prevalence of specific CHDs provides modest evidence for additional benefit from this intervention.

    Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction. CPB is a process routinely used during cardiac surgery for congenital heart disease. However, CPB has been related to increased endogenous catecholamines that can lead to major injuries in cardiomyocytes. The mechanisms involved are not completely understood. The aim of this study was to evaluate the alterations induced in the β-adrenergic receptors and GRK-2 present in atrial cardiomyocytes of infants with congenital heart disease undergoing surgical repair with CPB and correlate the alterations with functional and biochemical markers of ischemia/myocardial injury. The study consisted of right atrial biopsies of infants undergoing surgical correction in HC-FMRPUSP. Thirty-three cases were selected. Atrial biopsies were obtained at the beginning of CPB (group G1) and at the end of CPB (group G2). Real-time PCR, Western blotting, and immunofluorescence analysis were conducted to evaluate the expression of β1, β2-adrenergic receptors, and GRK-2 in atrial myocardium. Cardiac function was evaluated by echocardiography and biochemical analysis (N-terminal pro-brain natriuretic peptide (NT-ProBNP), lactate, and cardiac troponin I). We observed an increase in serum lactate, NT-proBNP, and troponin I at the end of CPB indicating tissue hypoxia/ischemia. Even without major clinical consequences in cardiac function, these alterations were followed by a significant increase in gene expression of β1 and β2 receptors and

    2014-01-01

    Abstract Standardization of the diagnostic routine for children with congenital heart disease associated with pulmonary arterial hypertension (PAH-CHD) is crucial, in particular since inappropriate assignment to repair of the cardiac lesions (e.g., surgical repair in patients with elevated pulmonary vascular resistance) may be detrimental and associated with poor outcomes. Thus, members of the Congenital Heart Disease and Pediatric Task Forces of the Pulmonary Vascular Research Institute decided to conduct a survey aimed at collecting expert opinion from different institutions in several countries, covering many aspects of the management of PAH-CHD, from clinical recognition to noninvasive and invasive diagnostic procedures and immediate postoperative support. In privileged communities, the vast majority of children with congenital cardiac shunts are now treated early in life, on the basis of noninvasive diagnostic evaluation, and have an uneventful postoperative course, with no residual PAH. However, a small percentage of patients (older at presentation, with extracardiac syndromes or absence of clinical features of increased pulmonary blood flow, thus suggesting elevated pulmonary vascular resistance) remain at a higher risk of complications and unfavorable outcomes. These patients need a more sophisticated diagnostic approach, including invasive procedures. The authors emphasize that decision making regarding operability is based not only on cardiac catheterization data but also on the complete diagnostic picture, which includes the clinical history, physical examination, and all aspects of noninvasive evaluation.

    Fetal magnetocardiography - a modern method of measuring electroactivity of fetal's heart is gaining more popularity interest among scientists and doctor's. For the method to become a useful tool in diagnosing congenital heart disease there has been created an international database composed of data taken from various scientific centers in the world (e.g. Institute of Precision and Biomedical Engineering of Warsaw University of Technology). Cardiograms which are recorded during fMCG (fetal magnetocardiography) and fECG (fetal electrocardiography) examination can be used to classify if the fetal heart is developing in healthy or pathological way. Thus, it has been extremely vital to create the universal and univocal pattern of discrimination between healthy or pathological fetuses. In order to do this an international database with normal values of the parameters describing the cardiograms was needed. The database is a compilation of data measured at various centers using different but similar devices and different signal processing techniques. This work analyses helpfulness of the international database in establishing the universal pattern which in future could serve as the basis for the proper congenital heart disease diagnosis.

    Apart from complete and incomplete congenital heart block (CHB), new cardiac manifestations related to anti-SSA/Ro antibodies have been reported in children born to mothers bearing these antibodies. These manifestations include transient fetal first-degree heart block, prolongation of corrected QT (QTc) interval, sinus bradycardia, late-onset cardiomyopathy, endocardial fibroelastosis and cardiac malformations. Anti-SSA/Ro antibodies are not considered pathogenic to the adult heart, but a prolongation of the QTc interval has recently been reported in adult patients and is still a matter of debate. Treatment of CHB is not well established and needs to be assessed carefully. The risks and benefits of prenatal fluorinated steroids are discussed. PMID:15743492

    Patients with Eisenmenger syndrome experience substantial morbidity and decreased survival rates. In advanced cases, lung transplantation with cardiac repair or heart-lung transplantation is often the only option. The efficacy of endothelin receptor antagonists in Eisenmenger syndrome, which has similar pathophysiology to idiopathic pulmonary hypertension, remains unknown.We retrospectively studied adults with congenital heart disease and Eisenmenger syndrome who were treated with endothelin receptor antagonists. Analysis included chart reviews of clinical evaluations, oxygen saturation levels, functional class, 6-minute walk distances, and pulmonary artery pressures. In the 24 patients studied, Eisenmenger syndrome was caused by ventricular septal defect (6 patients), atrial septal defect (5), atrioventricular canal defect (3), complex congenital heart disease (9), and patent ductus arteriosus (1).Eisenmenger syndrome was treated with bosentan (21 patients) and sitaxsentan (3 patients). On average, therapy lasted 19 +/- 12 months. Subsequently, mean 6-minute walk distances improved from 226 +/- 159 m to 351 +/- 113 m (P = 0.004), and World Health Organization functional class improved > or =1 grade (P < 0.0001). Oxygen saturations increased on therapy from 80.5% to 87% (P < 0.0001). Pulmonary arterial systolic pressures decreased from 97 +/- 21 mmHg to 78 +/- 27 mmHg, and mean pressures from 59 +/- 16 mmHg to 47 +/- 17 mmHg (both P < 0.0001). Neither major complications from therapy nor changes in pulmonary capillary wedge pressure occurred.Endothelin receptor antagonists may play an important role in improving 6-minute walk distance, oxygen saturation, pulmonary artery pressures, and symptoms in adults who have congenital heart defects and Eisenmenger syndrome.

    Purpose. The purpose of present study was to construct the best screening model of congenital heart disease serum markers and to provide reference for further prevention and treatment of the disease. Methods. Documents from 2006 to 2014 were collected and meta-analysis was used for screening susceptibility genes and serum markers closely related to the diagnosis of congenital heart disease. Data of serum markers were extracted from 80 congenital heart disease patients and 80 healthy controls, respectively, and then logistic regression analysis and support vector machine were utilized to establish prediction models of serum markers and Gene Ontology (GO) functional annotation. Results. Results showed that NKX2.5, GATA4, and FOG2 were susceptibility genes of congenital heart disease. CRP, BNP, and cTnI were risk factors of congenital heart disease (p < 0.05); cTnI, hs-CRP, BNP, and Lp(a) were significantly close to congenital heart disease (p < 0.01). ROC curve indicated that the accuracy rate of Lp(a) and cTnI, Lp(a) and BNP, and BNP and cTnI joint prediction was 93.4%, 87.1%, and 97.2%, respectively. But the detection accuracy rate of the markers' relational model established by support vector machine was only 85%. GO analysis suggested that NKX2.5, GATA4, and FOG2 were functionally related to Lp(a) and BNP. Conclusions. The combined markers model of BNP and cTnI had the highest accuracy rate, providing a theoretical basis for the diagnosis of congenital heart disease. PMID:27118988

    The final therapy of 'end-stage heart failure' is orthotopic heart, lung or heart-lung transplantation. However, these options are not available for many patients worldwide. Therefore, novel therapeutical strategies are needed. Based on pathophysiological insights regarding (1) the long-term impact of an obstructive pulmonary outflow tract in neonates with congenitally corrected transposition of the great arteries, (2) the importance of a restrictive versus a non-restrictive atrial septum in neonates born with a borderline left ventricle and (3) the significance of both, a patent foramen ovale and/or open ductus arteriosus for survival of newborns with persistent pulmonary hypertension, the current review introduces some therapeutical strategies that may be applicable to selected patients with heart failure. These strategies include (1) reversible pulmonary artery banding in left ventricular-dilated cardiomyopathy with preserved right ventricular function, (2) the creation of restrictive interatrial communication to treat diastolic (systolic) heart failure, (3) atrioseptostomy or reverse Potts shunt in pulmonary arterial hypertension and (4) return to a fetal, parallel circulation by combining atrioseptostomy and reversed Potts shunt with or without placement of a bilateral pulmonary artery banding. While still being experimental, it is hoped that the procedures presented in the current overview will inspire future novel therapeutic strategies that may be applicable to selected patients with heart failure.

    For patients with end-stage heart failure and contraindications to transplantation, insertion of a continuous-flow left ventricular assist device (LVAD) is an effective treatment strategy. We present a case of LVAD insertion in a 46-year-old man with cyanotic complex congenital heart disease and an extensive surgical history who presented with failure of his systemic ventricle. The insertion of an LVAD in our patient restored cardiac output and improved cyanosis and native ventricular function. As the number of patients with congenital heart defects surviving to adulthood increases, destination LVAD therapy may be increasingly considered as an alternative.

    Background Congenital heart defects (CHDs) are the most common fetal defects and the most important cause of child mortality and morbidity. Objective To investigate the association between growth/differentiation factor 1 (GDF1) polymorphisms and fetal CHDs, by evaluating the association of GDF1 rs4808863 with fetal CHDs. Design A case–control study. Setting Beijing, China. Participants We selected 124 fetuses with a CHD and a normal karyotype and normal array-based comparative genomic hybridisation analysis and compared them with 124 normal fetuses matched for gestational age and sex. Fetuses with a CHD, from 20 to 32 weeks of gestation were included. Fetuses with any chromosomal abnormalities, and fetuses from multiple pregnancies and those carried by pregnant women with chronic diseases, were excluded from this research. DNA extraction and genotyping were carried out for all cases to investigate the genotype distributions of GDF1 rs4808863. Results A significant difference was noted for the CT phenotype of GDF1 rs4808863 between the controls and the fetuses with CHDs using homozygote and heterozygote comparisons. The minor allele (T allele) of GDF1 rs4808863 was associated with an increased risk of CHD (p<0.05). A statistically significant difference between controls and fetuses with CHDs was noted in a comparison with the mutation genotype CT+TT and wild-type genotype CC (p<0.05) using dominant modal analysis. After stratification analysis, the CT phenotype, the minor allele (T allele) and the mutation genotype CT+TT of the rs4808863 polymorphism were associated with atrioventricular septal defect (AVSD), left ventricular outflow tract obstruction (LVOTO) and left–right laterality defects (p<0.05). Conclusions Our results suggest that the GDF1 rs4808863 polymorphism contributes to an increased risk of fetal CHDs, especially the subtypes of AVSD, LVOTO and left–right laterality defects.

    2015-01-01

    Background and objectives In 2011, the U.S. Secretary of Health and Human Services recommended universal screening of newborns for critical congenital heart defects (CCHD), yet few estimates of the number of infants with CCHD likely to be detected through universal screening exist. Our objective was to estimate the number of infants with nonsyndromic CCHD in the United States likely to be detected (true positives) and missed (false negatives) through newborn CCHD screening. Methods We developed a simulation model based on estimates of birth prevalence, prenatal diagnosis, late detection, and sensitivity of newborn CCHD screening through pulse oximetry to estimate the number of true positive and false negative nonsyndromic cases of the seven primary and five secondary targets of CCHD screening identified through screening. Results We estimated that 875 (95% uncertainty interval [UI]: 705–1,060) U.S. infants with nonsyndromic CCHD, including 470 (95% UI: 360–585) among primary CCHD screening targets, will be detected annually through CCHD newborn screening. An additional 880 (UI: 700–1,080) false negative screenings, including 280 (95% UI: 195–385) among primary screening targets, are expected. We estimated that similar numbers of CCHD (within ~1 case/10,000 live births) would be detected under scenarios comparing “lower” (~19%) and “higher” (~42%) than current prenatal detection prevalences. Conclusions A substantial number of nonsyndromic CCHD cases are likely to be detected through universal CCHD screening; however, an equal number of false negative screenings, primarily among secondary targets of screening, are likely to occur. Future efforts should document the true impact of CCHD screening in practice. PMID:25963011

    Child development may be subject to forms of motor, physical, cognitive and self-representation impairments when complex congenital heart disease (CHD) occurs. In some cases, inadequacy of both self-representation as well as the family system are displayed. It seems to be important to search the likely internal and external resources of the CHD child, and the possible connections among such resources, which may help him/her to manage his/her own risk condition. The research project inquires the possible resources related to the self-representation and self-esteem levels of the CHD child, and those related to maternal self-perception as competent mothers. A group of 25 children (mean age = 10.2; SD=1.8) suffering from specific forms of CHD, and a group made up of their relative mothers (mean age = 38.2; SD=5) were studied. The tools used were the Human Figure Drawing, to investigate child body-related self-representation; the TMA scale (Self-esteem Multidimensional Test), to investigate the child's self-esteem; and the Q-sort questionnaire, to assess how mothers perceived their maternal competence. Data concerning the likely correlations between the child's self-representation and the maternal role competence show [that] positive correlations between some indicators of maternal competence, specific aspects of CHD children's self-representation (mothers' emotional coping and children's self-image adequacy) and self-esteem (mothers' emotional scaffolding and children's self-esteem at an emotional level). By detecting the occurrence of specific correlations among resources of both child and mother, the study provides cardiologists with information that is useful for building a relationship with the families concerned, which would seem to enhance the quality of the process of the cure itself.

    Background: Delayed or missed diagnosis of critical and cyanotic congenital heart disease (CHD) in asymptomatic newborns may result in significant morbidity and mortality. The aim of this study was to determine the accuracy of pulse oximetry screening performed on the first day of life for the early detection of critical and cyanotic CHD in apparently normal newborns. Methods: This cross-sectional study used postductal pulse oximetry to evaluate term neonates born between 2008 and 2011 with normal physical examinations. Functional oxygen saturation < 95% was considered abnormal, and second measurement was done 2 hours later. If the second measurement remained < 95%, an echocardiogram was performed. On enrolment in the study, the following data for each neonate were recorded: gestational age, gender, birth weight, mode of delivery, and mother’s age. Results: During the study period, totally 3,846 newborns were evaluated. Of the whole study population, 304 (7.9%) babies had a postductal functional saturation < 95%. The second measurement was also < 95% in 104 (2.7%) neonates. The mean age of the neonates at the time of pulse oximetry was 18.91 ± 8.61 (min = 4.5 and max = 49) hours. Forty-nine percent of the subjects were female and 51% were male. Echocardiography was performed on 81 out of 104 newborns, and 14 (0.36%) of them had CHD. The types of CHD in our patients were tetralogy of Fallot (3 cases), transposition of the great vessels (2 cases), double-outlet right ventricle (2 cases), truncus arteriosus, total anomalous pulmonary venous return, atrioventricular septal defect, pulmonary atresia, persistent pulmonary hypertension, ventricular septal defect, and atrial septal defect (1 case for each type). The best time for pulse oximetry was within 8-24 hours of the newborns’ life. Conclusion: Pulse oximetry screening along with clinical examination may be able to assist in the early detection of critical and cyanotic CHD in asymptomatic newborns. PMID:27928258

    2013-04-19

    In August 2011, New Jersey implemented a statewide newborn screening protocol for critical congenital heart defects (CCHD) using pulse oximetry. In January 2012, CDC responded to a request from the New Jersey Department of Health (NJDOH) to assist with an assessment of the implementation. Out of the 52 birthing facilities in New Jersey, a sample of 11 was selected. Staff interviews were conducted to assess screening and data collection processes, data flow and tracking procedures, electronic medical record (EMR) capabilities, and capacity to report data to NJDOH. Feedback also was obtained about the questionnaire being used to follow-up on positive screening results. All 11 facilities were screening for CCHD. Among the 11 facilities, three were electronically entering and maintaining data into an EMR, five were manually entering and maintaining data into paper charts and logs, and three were both electronically and manually entering and maintaining data. Facilities reported that implementation of newly mandated CCHD screening posed a low burden to hospital staff members. NJDOH receives aggregate pulse oximetry screening data from all New Jersey birthing facilities. During the first 3 months of screening, preliminary data indicated that 98.2% of 25,214 newborns were screened. Hospitals reported data on 12 newborns with positive screening results; two newborns were newly diagnosed with CCHD as a result of pulse oximetry screening. Because of state-specific factors, such as out-of-state referral patterns, these findings might underestimate the anticipated number of positive screens in states with varying referral patterns and use of prenatal diagnosis. Rapid implementation of universal CCHD screening posed a relatively low burden to hospitals in New Jersey.

    Abnormalities of the lymphatic circulation are well recognized in patients with congenital heart defects. However, it is not known how the associated abnormal blood flow patterns, such as increased pulmonary blood flow (PBF), might affect pulmonary lymphatic function and structure. Using well-established ovine models of acute and chronic increases in PBF, we cannulated the efferent lymphatic duct of the caudal mediastinal node and collected and analyzed lymph effluent from the lungs of lambs with acutely increased PBF (n = 6), chronically increased PBF (n = 6), and age-matched normal lambs (n = 8). When normalized to PBF, we found that lymph flow was unchanged following acute increases in PBF but decreased following chronic increases in PBF. The lymph:plasma protein ratio decreased with both acute and chronic increases in PBF. Lymph bioavailable nitric oxide increased following acute increases in PBF but decreased following chronic increases in PBF. In addition, we found perturbations in the transit kinetics of contrast material through the pleural lymphatics of lambs with chronic increases in PBF. Finally, there were structural changes in the pulmonary lymphatic system in lambs with chronic increases in PBF: lymphatics from these lambs were larger and more dilated, and there were alterations in the expression of vascular endothelial growth factor-C, lymphatic vessel endothelial hyaluronan receptor-1, and Angiopoietin-2, proteins known to be important for lymphatic growth, development, and remodeling. Taken together these data suggest that chronic increases in PBF lead to both functional and structural aberrations of lung lymphatics. These findings have important therapeutic implications that warrant further study.

    The current standard for prenatal screening is mostly based on biochemical marker tests and the use of ultrasonography. There is no secure stand-alone screening marker for congenital heart defects (CHDs). MicroRNAs (miRNAs) that are associated with cardiogenesis enter the maternal peripheral bloodstream during pregnancy and allow non-invasive prenatal testing (NIPT). The present study investigated the plasma expression profile of fetal hsa-miR-99a in maternal blood. Peripheral blood samples were collected from 39 pregnant patients, comprising 22 with CHD-positive fetuses and 17 with CHD-free controls. miRNAs were isolated from the maternal serum and reverse transcription-quantitative polymerase chain reaction was carried out to determine the expression of hsa-miR-99a. While the miRNA concentrations were almost identical among the affected and control groups (5.54 vs. 6.40 ng/µl), significantly upregulated hsa-miR-99a levels were identified in the affected group (1.78×10−2±3.53×10−2 vs. 1.09×10−3±3.55×10−3 ng/µl, P=0.038). In conclusion, according to the present study, hsa-miR-99a is involved in cardiac malformation and may serve as a biomarker during fetal development, and therefore presents as a candidate for monitoring cardiomyogenesis and potential use as a NIPT-biomarker for fetal CHD.

    The dual endothelin receptor antagonist, bosentan, has been shown to be well tolerated and effective in improving pulmonary arterial hypertension (PAH) symptoms in patients with Eisenmenger syndrome but data from longer-term studies are lacking. The aim of this study was to retrospectively analyze the long-term efficacy and safety of bosentan in adults with PAH secondary to congenital heart disease (PAH-CHD). Prospectively collected data from adult patients with PAH-CHD (with and without Down syndrome) initiated on bosentan from October 2007 through June 2010 were analyzed. Parameters measured before bosentan initiation (62.5 mg 2 times/day for 4 weeks titrated to 125 mg 2 times/day) and at each follow-up (1 month and 3, 6, 9, 12, 18, and 24 months) included exercise capacity (6-minute walk distance [6MWD]), pretest oxygen saturation, liver enzymes, and hemoglobin. Data were analyzed from 39 patients with PAH-CHD (10 with Down syndrome) who had received ≥ 1 dose of bosentan (mean duration of therapy 2.1 ± 1.5 years). A significant (p < 0.0001) average improvement in 6MWD of 54 m over a 2-year period in patients with PAH-CHD without Down syndrome was observed. Men patients had a 6MWD of 33 m greater than women (p < 0.01). In all patients, oxygen saturation, liver enzymes, and hemoglobin levels remained stable. There were no discontinuations from bosentan owing to adverse events. In conclusion, patients with PAH-CHD without Down syndrome gain long-term symptomatic benefits in exercise capacity after bosentan treatment. Men seem to benefit more on bosentan treatment. Bosentan appears to be well tolerated in patients with PAH-CHD with or without Down syndrome.

    With the application of advanced molecular cytogenetic techniques, the number of patients identified as having abnormal chromosome 8p has increased progressively. Individuals with terminal 8p deletion have been extensively described in previous studies. The manifestations usually include cardiac anomalies, developmental delay/mental retardation, craniofacial abnormalities, and multiple other minor anomalies. However, some patients with proximal deletion also presented with similar phenotypic features. Here we describe a female child with an 18.5-Mb deletion at 8p11.23–p22 that include the cardiac-associated loci NKX2-6 and NRG1. Further mutation screening of these two candidate genes in 143 atrial septal defect patients, two heterozygous mutations NKX2-6 (c.1A > T) and NRG1 (c.1652G > A) were identified. The mutations were described for the first time in patients with congenital heart disease (CHD). The c.1A > T NKX2-6 generated a protein truncated by 45 amino acids with a decreased level of mRNA expression, whereas the NRG1 mutation had no significant effect on protein functions. Our findings suggest that 8p21-8p12 may be another critical region for 8p-associated CHD, and some cardiac malformations might be due to NKX2-6 haploinsufficiency. This study also links the NKX2-6 mutation to ASD for the first time, providing novel insight into the molecular underpinning of this common form of CHD. PMID:27808268

    Objectives Critical congenital heart disease (CCHD) was added recently to the U.S. Recommended Uniform Screening Panel for newborns. This study assessed whether maternal/household and infant characteristics were associated with late CCHD detection. Methods This was a state-wide, population-based, retrospective, observational study of infants with CCHD born 1998-2007 identified by the Florida Birth Defects Registry. We examined 12 CCHD conditions that are primary and secondary targets of newborn CCHD screening by pulse oximetry. We used Poisson regression models to analyze associations between selected characteristics (e.g., maternal age, CCHD type, and birth hospital nursery level [highest level available in the hospital]) and late CCHD detection, which was defined as diagnosis after the birth hospitalization. Results Of 3,603 infants with CCHD and linked hospitalizations, CCHD was not detected during the birth hospitalization for 22.9% (n=825) of infants. The likelihood of late detection varied by CCHD condition. Infants born in a birth hospital with a Level I nursery only (adjusted prevalence ratio [aPR] 1.9, 95% confidence interval (CI) 1.6-2.2) or Level II nursery (aPR 1.5, 95% CI 1.3-1.7) were significantly more likely to have late-detected CCHD compared to infants born in a birth hospital with a Level III (highest) nursery. Conclusions After controlling for the selected characteristics, hospital nursery level appears to have an independent association with late CCHD detection. Thus, perhaps universal newborn screening for CCHD could be particularly beneficial in Levels I and II nurseries and may reduce differences in the frequency of late diagnosis between birth hospital facilities.

    BACKGROUND Critical congenital heart disease (CCHD) was recently added to the U.S. Recommended Uniform Screening Panel for newborns. States considering screening requirements may want more information about the potential impact of screening. This study examined potentially avoidable mortality among infants with late detected CCHD and assessed whether late detection was associated with increased hospital resource use during infancy. METHODS This was a state-wide, population-based, observational study of infants with CCHD (n =3603) born 1998 to 2007 identified by the Florida Birth Defects Registry. We examined 12 CCHD conditions that are targets of newborn screening. Late detection was defined as CCHD diagnosis after the birth hospitalization. Deaths potentially avoidable through screening were defined as those that occurred outside a hospital following birth hospitalization discharge and those that occurred within 3 days of an emergency readmission. RESULTS For 23% (n =825) of infants, CCHD was not detected during the birth hospitalization. Death occurred among 20% (n =568/2,778) of infants with timely detected CCHD and 8% (n =66/825) of infants with late detected CCHD, unadjusted for clinical characteristics. Potentially preventable deaths occurred in 1.8% (n =15/825) of infants with late detected CCHD (0.4% of all infants with CCHD). In multivariable models adjusted for selected characteristics, late CCHD detection was significantly associated with 52% more admissions, 18% more hospitalized days, and 35% higher inpatient costs during infancy. CONCLUSION Increased CCHD detection at birth hospitals through screening may lead to decreased hospital costs and avoid some deaths during infancy. Additional studies conducted after screening implementation are needed to confirm these findings. PMID:24000201

    Background Children with congenital heart disease (CHD) are at risk for developmental delay (DD). This study sought to identify early risk factors for abnormal developmental trajectories in children with CHD. Methods and Results Children with CHD at high risk for DD, without known genetic abnormality, and with ≥3 assessments using the Bayley Scales of Infant Development-III (BSID-III) were studied. Logistic regression was used to assess the impact of patient and clinical factors on cognitive, language, and motor score trajectories; classified as: “Average or Improved” if all scores were ≥ 85 (< 1SD below mean) or increased to ≥ 85 and never decreased; or “Abnormal” if all scores were < 85, fell to < 85 and never improved, or fluctuated above and below 85. Data on 131 children with 527 BSID-III assessments were analyzed. Subject age was 5.5–37.4 months. Overall, 56% had cognitive, language, and motor development in the average range. Delays occurred in single domains in 23%. Multiple domains were delayed in 21%. More cardiac surgeries, longer hospital stay, poorer linear growth, and tube feeding were associated with worse outcomes in all domains (p<0.05). In the multivariable model, need for tube feeding was a risk factor for having an abnormal developmental trajectory (OR = 5.1–7.9). Minority race and lack of private insurance had significant relationships with individual domains. Conclusions Longitudinal developmental surveillance identified early factors that can help quantify risk of DD over time. Strategies to improve modifiable factors and early therapeutic intervention can be targeted to children at highest risk. PMID:26304667

    BACKGROUND AND OBJECTIVE: Children with congenital heart disease (CHD) are at risk for developmental delay (DD). Changes in cognitive, language, and motor skills in early childhood have not been described. We report the results of a structured approach using longitudinal testing to identify problems and ensure early intervention in accordance with published guidelines. METHODS: Bayley Scales of Infant Development, Third Edition, were used to assess cognitive, language, and motor skills in 99 children with CHD. Subjects were evaluated 3 to 6 times in the first 3 years of life. DD was defined as scores >1 SD below the population mean. RESULTS: Cardiac anatomy was single ventricle (1V) in 34 subjects and 2 ventricles (2V) in 65. Medical comorbidities were present in 21% and genetic syndromes in 19%. Most subjects (75%) had DD in ≥1 area at ≥1 assessments. Subjects with 1V anatomy had equivalent outcomes to those with 2V. Cognitive and language scores declined in subjects with genetic syndromes but were stable and within the average range for subjects with 1V and 2V. Motor scores improved for subjects with 1V and 2V but remained low for those with genetic syndromes. In addition to age, need for supplemental tube feeding, longer cardiopulmonary bypass time, and shorter time since last hospitalization were significant predictors of developmental outcomes. CONCLUSIONS: DDs in young children with CHD are both common and dynamic. Providers should encourage longitudinal surveillance for children with CHD because exposure to risk and prevalence of DD change over time. PMID:24488746

    Introduction Balloon angioplasty (BAP) and aortic or pulmonary balloon valvuloplasty (BAV, BPV) are well-established treatment options in congenital heart defects. Recently, significant technological progress has been made and new catheters have been implemented in clinical practice. Aim To analyze the results of BAP, BAV and BPV with the new balloon catheter Valver and its second generation Valver II, which the company Balton (Poland) launched and developed. These catheters have not been clinically evaluated yet. Material and methods We performed 64 interventions with Valver I and Valver II. With Valver I the following procedures were performed: 17 BPV (including 9 in tetralogy of Fallot – TOF), 10 BAV and 27 BAP in coarctations of the aorta (CoA) – including 9 native and 18 after surgery. With Valver II ten interventions were done – 3 BPV, 2 pulmonary supravalvular BAP (after switch operations), 2 BAP of recoarctations and 3 other BAP. Age of the patients ranged from a few days to 40 years. Results All procedures were completed successfully, without rupture of any balloon catheters. The pressure gradient drop was statistically significant in all groups: BPV in isolated pulmonary valvular stenosis 28.1 mm Hg (mean), BPV in TOF 18.7 mm Hg, BAV 32.8 mm Hg, BAP in native CoA 15.4 mm Hg and in recoarctations 18.6 mm Hg. In 3 cases during rapid deflation of Valver I, wrinkles of the balloons made it impossible to insert the whole balloon into the vascular sheath (all were removed surgically from the groin). No such complication occured with Valver II. Conclusions Valver balloon catheters are an effective treatment modality in different valvular and vascular stenoses. PMID:27625686

    Objective Preoperative brain injury, particularly stroke and white matter injury (WMI), is common in newborns with congenital heart disease (CHD). The objective of this study was to determine the risk of hemorrhage or extension of preoperative brain injury with cardiac surgery. Methods This dual-center prospective cohort study recruited 92 term newborns: 62 with transposition of the great arteries (TGA), and 30 with single ventricle physiology from two tertiary referral centers. Newborns underwent brain MRI scans before and after cardiac surgery. Results Brain injury was identified in 40 (43%) newborns on the preoperative MRI scan (median five days of life): stroke in 23, WMI in 21, and intraventricular hemorrhage in 7. None of the brain lesions presented clinically with overt signs or seizures. Preoperative brain injury was associated with balloon atrial septostomy (BAS) (P=0.003) and lowest SaO2 (P=0.007); in a multivariable model, only the effect of BAS remained significant when adjusting for lowest SaO2. On postoperative MRI in 78 newborns (median 21 days of life), none of the preoperative lesions showed evidence of extension or hemorrhagic transformation (0/40 [95% CI: 0-7%]). The presence of preoperative brain injury was not a significant risk factor for acquiring new injury on the postoperative MRI (P=0.8). Conclusion Clinically silent brain injuries identified preoperatively in newborns with CHD, including stroke, have a low risk of progression with surgery and cardiopulmonary bypass, and should therefore not delay clinically indicated cardiac surgery. In this multi-center cohort, BAS remains an important risk factor for preoperative brain injury, particularly stroke. PMID:20434174

    Changes in plasma von Willebrand factor concentration (VWF:Ag) and ADAMTS-13 activity (the metalloprotease that cleaves VWF physiologically) have been reported in several cardiovascular disorders with prognostic implications. We therefore determined the level of these proteins in the plasma of children with cyanotic congenital heart disease (CCHD) undergoing surgical treatment. Forty-eight children were enrolled (age 0.83 to 7.58 years). Measurements were performed at baseline and 48 h after surgery. ELISA, collagen-binding assays and Western blotting were used to estimate antigenic and biological activities, and proteolysis of VWF multimers. Preoperatively, VWF:Ag and ADAMTS-13 activity were decreased (65 and 71% of normal levels considered as 113 (105-129) U/dL and 91 ± 24% respectively, P < 0.003) and correlated (r = 0.39, P = 0.0064). High molecular weight VWF multimers were not related, suggesting an interaction of VWF with cell membranes, followed by proteolytic cleavage. A low preoperative ADAMTS-13 activity, a longer activated partial thromboplastin time and the need for cardiopulmonary bypass correlated with postoperative bleeding (P < 0.05). Postoperatively, ADAMTS-13 activity increased but less extensively than VWF:Ag (respectively, 2.23 and 2.83 times baseline, P < 0.0001), resulting in an increased VWF:Ag/ADAMTS-13 activity ratio (1.20 to 1.54, respectively, pre- and postoperative median values, P = 0.0029). ADAMTS-13 consumption was further confirmed by decreased ADAMTS-13 antigenic concentration (0.91 ± 0.30 to 0.70 ± 0.25 µg/mL, P < 0.0001) and persistent proteolysis of VWF multimers. We conclude that, in pediatric CCHD, changes in circulating ADAMTS-13 suggest enzyme consumption, associated with abnormal structure and function of VWF. PMID:23558858

    The incidence and risk factors for prosthetic pulmonary valve failure (PPVF) should be considered when determining optimal timing for pulmonary valve replacement (PVR) in asymptomatic patients with congenital heart disease (CHD). The cumulative freedom for reintervention due to PPVF after 146 PVR in 114 patients with CHD was analyzed. Six potential risk factors (underlying cardiac defect, history of palliative procedures, number of previous cardiac interventions, hemodynamic indication for PVR, type of intervention, and age at intervention) were analyzed using Cox proportional hazard modeling. Receiver operating characteristic (ROC) curves were used for discrimination. Internal validation in patients with tetralogy of Fallot was also performed. Median age at intervention was 23 years. There were 60 reinterventions due to PPVF (41%). Median event-free survival was 14 years (95% confidence interval [CI] 12 to 16 years). The only independent risk factor was the age at intervention (hazard ratio [HR] 0.93, 95% CI 0.90 to 0.97; p = 0.001; area under the ROC curve 0.95, 95% CI 0.92 to 0.98; p <0.001). The best cut-off point was 20.5 years. Freedom from reintervention for PPVF 15 years after surgery was 70% when it was performed at age >20.5 years compared with 33% when age at intervention was <20.5 years (p = 0.004). Internal validation in 102 PVR in patient cohort with tetralogy of Fallot (ROC area 0.98, 95% CI 0.96 to 1.0; p <0.001) was excellent. In conclusion, age at intervention is the main risk factor of reintervention for PPVF. The risk of reintervention is 2-fold when PVR is performed before the age of 20.5 years.

    Surgical correction or palliation of congenital heart disease (CHD) often requires augmenting the main pulmonary artery (MPA) with non-native material or placing a cylindrical graft. The degree to which this intervention affects PA compliance is largely unknown. In this study, the MPA stiffness characteristics were assessed by its compliance, distensibility, and pressure-strain modulus. Coregistered velocity encoded phase-contrast MRI and cardiac catheterization data were available for a cohort of repaired CHD patients (n=8) and controls (n=3). All patients were repaired with either an RV-PA conduit or a RV outflow tract patch. We measured the MPA area change by MRI and MPA pressure during the cath. The measurements were taken through or just distal to the conduit. The MPA compliance and distensibility for the patients were significantly lower than the controls: compliance (9.8±10.8 vs 28.3±7.7mm^2/mmHg, p<0.05), distensibility (2.2±1.5 vs 6.6±2.1%Area change/mmHg, p=0.05). The patients had a significantly higher pressure-strain modulus (152.3±116.4mmHg, p<0.05) than the controls (35.8±10.6mmHg). The abnormally elevated PA stiffness due to the rigidity of the conduit or patch material may cause a compliance mismatch resulting in high stress levels contributing to the observed progressive PA dilatation. This may be a factor in the progressive RV dilatation seen in this cohort of repaired CHD patients.

    Digital subtraction angiography (DSA) permits high-resolution cardiac imaging with relatively low doses of contrast medium and reduced radiation exposure. These are potential advantages in children with congenital heart disease. Computer-based DSA (30 frames/sec) and conventional cutfilm angiography (6 frames/sec) or cineangiography (60 frames/sec) were compared in 42 patients, ages 2 months to 18 years (mean 7.8 years) and weighing 3.4 to 78.5 kg (mean 28.2 kg). There were 29 diagnoses that included valvular regurgitant lesions, obstructive lesions, various shunt abnormalities, and a group of miscellaneous anomalies. For injections made at a site distant from the lesion and on the right side of the circulation, the mean dose of contrast medium was 60% to 100% of the conventional dose given during standard angiography. With injections made close to the lesion and on the left side of the circulation, the mean dose of contrast medium was 27.5% to 42% of the conventional dose. Radiation exposure for each technique was markedly reduced in all age groups. A total of 92 digital subtraction angiograms were performed. Five studies were suboptimal because too little contrast medium was injected; in the remaining 87 injections, DSA and conventional studies resulted in identical diagnoses in 81 instances (p less than .001 vs chance). The remaining six injections made during DSA failed to confirm diagnoses made angiographically by standard cutfilm angiography or cineangiography. We conclude that DSA usually provides diagnostic information equivalent to that available from cutfilm angiography and cineangiography, but DSA requires considerably lower doses of contrast medium and less radiation exposure than standard conventional methods.

    Recent studies described a number of fetal development sides related to the environmental physical activity. The aim of this study was to check the possible links between congenital heart disease (CHD) born in a non-selected medical network and indices of environmental physical activity. Children born with CHD in Kaunas, Lithuania, in years 1995-2005 were analyzed at the end of the first year of life (including also those died after birth from this condition). Monthly distribution of CHD (total - 371, both gender (178 boys and 193 girls), 41435 births) were compared with parameters of solar (SA), geomagnetic (GMA) and cosmic ray (CRA) activity, as well as the year, at the month of birth, 9 months before and at year of birth and one year before. CRA was represented by neutron activity on the Earth's surface. Heliogeophysical data were obtained from space research centers in the USA, Russia and Finland. There was found a significant correlation between yearly number of births (r = - 0.9, p = 0.00012). Monthly number of CHD was correlated with SA and CRA often highly at the beginning of pregnancy both in monthly and yearly (r = - 0.7, p = 0.025 for SA, r = 0.8, p = 0.005 for CRA) comparison. For boys the correlation was stronger, but also it was significant for girls. GMA has not shown significant effects. It is concluded that the number of yearly and monthly CHD is connected with SA and CRA in pregnancy. Boys show high levels in these correlations. The mechanism of the cosmophysical effects on human development and temporal distribution of CHD deserve special studies.

    Background: Bacterial infection (BI) after congenital heart surgery (CHS) is associated with increased morbidity and is difficult to differentiate from systemic inflammatory response syndrome caused by cardiopulmonary bypass (CPB). Procalcitonin (PCT) has emerged as a reliable biomarker of BI in various populations. Aim: To determine the optimal PCT threshold to identify BI among children suspected of having infection following CPB. Setting and Design: Single-center retrospective observational study. Materials and Methods: Medical records of all the patients admitted between January 2013 and April 2015 were reviewed. Patients in the age range of 0-21 years of age who underwent CHS requiring CPB in whom PCT was drawn between postoperative days 0-8 due to suspicion of infection were included. Statistical Analysis: The Wilcoxon rank-sum test was used for nonparametric variables. The diagnostic performance of PCT was evaluated using a receiver operating characteristic (ROC) curve. Results: Ninety-eight patients were included. The median age was 2 months (25th and 75th interquartile of 0.1-7.5 months). Eleven patients were included in the BI group. The median PCT for the BI group (3.42 ng/mL, 25th and 75th interquartile of 2.34-5.67) was significantly higher than the median PCT for the noninfected group (0.8 ng/mL, 25th and 75th interquartile 0.38-3.39), P = 0.028. The PCT level that yielded the best compromise between the sensitivity (81.8%) and specificity (66.7%) was 2 ng/mL with an area under the ROC curve of 0.742. Conclusion: A PCT less than 2 ng/mL makes BI unlikely in children suspected of infection after CHS. PMID:27212844

    Congenital heart disease (CHD) can cause pulmonary hypertension (PH) in children, and surgery to correct CHD may be complicated by postoperative pulmonary hypertensive crises (PHC). Clinical data regarding the use of inhaled iloprost to treat children with PH are scarce. Our aim was to determine the efficacy and safety of iloprost in children with PH following surgery to correct CHD. This was a randomized, placebo-controlled study of 22 children (median age 7 months) undergoing surgery to achieve biventricular repair. The combined clinical endpoint was a decrease of more than 20% in the ratio of systolic pulmonary arterial pressure to systolic arterial pressure or pulmonary resistance to systemic resistance, with no PHC or death. Patients were randomized to receive low-dose iloprost (30 ng/kg/min), high-dose iloprost (50 ng/kg/min), or placebo, for 10 min every 2 hr in the first 48 hr after surgery. PHC were experienced by two patients who received placebo and one patient treated with high-dose iloprost. The combined clinical endpoint was reached by six patients administered low-dose iloprost (P = 0.005) and four administered high-dose iloprost (P = 0.077), compared with none in the placebo group. Patients treated with iloprost showed a significant reduction from baseline in mean pulmonary vascular resistance index (-2.2 Wood units, P < 0.05), whereas patients who received placebo showed no significant change. This study supports the use of iloprost to treat children with PH following surgery to correct CHD.

    Abstract South America is a territory of 17,819,100 km2, where ∼388 million people live in 13 countries. In the region, access to medical assistance (e.g., for treatment of cardiovascular disorders) is relatively easy in metropolitan areas but difficult in remote places such as the Andes and the Amazon. Altitudes up to ∼6,700 m influence the prevalence of congenital heart disease (CHD) and pulmonary arterial hypertension (PAH). In tertiary centers, CHD is now treated earlier in life but remains an important etiology of PAH. In adolescents and adults with PAH assisted at institutions devoted to treatment of cardiovascular disorders, the relative frequency of PAH-CHD (∼50%–60%) is even higher than that of idiopathic PAH. In one big tertiary center in São Paulo, Brazil, the prevalence of advanced PAH in children and adults with CHD is 1.2% and 4.2%, respectively. In young patients with cardiac septal defects (aged up to 2 years), pulm
