This comprehensive (two fascicle) technical report describes and details the progress made in the development and evaluation of a long-term low profile intracorporeal (abdominal) left ventricular assist device (THI E-Type ALVAD). Fascicle I describes the ...

Endovascular abdominal aortic aneurysm repair in decompensated heart failure patients requiring ventricular assist device (VAD) placement needs careful consideration of both complex disease states. We present this clinical dilemma and describe our choice of transcatheter aneurysm repair in the face of advanced refractory heart failure following VAD ...

A 54-year-old woman with occlusive disease of the distal abdominal aorta was referred for pre-operative risk assessment, and was diagnosed with severe impairment of the left ventricular function due to left main stem coronary artery stenosis. Low-dose dobutamine stress echocardiography did not demonstrate ...

The report covers the evaluation of Left Ventricular Assist Devices during preclinical trials. Forty-eight in vivo experiments were carried out with either an external Model X LVAD or an internal Model VII abdominal LVAD. Patient selection forms, consent ...

The document summarizes the development of two short-term left ventricular assist systems by Thermo Electron Corporation. An abdominally positioned Model VII ALVAD is being prepared for use at the Texas Heart Institute and an extracorporeal Model X LVAD f...

To evaluate the effect of aortic occlusion and limb reperfusion on global and regional function of the right and left ventricle during infrarenal abdominal aortic aneurysm repair, 23 patients underwent five intraoperative first-pass radionuclide angiocardiograms: 1) before the skin incision, 2) at aortic cross-clamp, 3) 20 minutes after aortic occlusion, ...

... often in the lower-left chamber (called the left ventricle). These aneurysms are called left ventricular aneurysms, and ... heart attack can weaken the wall of the left ventricle.) If a left ventricular aneurysm leads to an ...

Intra-aortic balloon pump (IABP) counterpulsation is a useful hemodynamic assist device during complex percutaneous coronary intervention (PCI) in patients with poor left ventricular function; however, the presence of an abdominal aortic aneurysm poses a problem, because insertion via the femoral artery may cause distal embolism and ...

In 1974, between 2 and 8% of the 50,000 adult patients undergoing cardiac surgery in this country succumbed in the early post-operative period from left ventricular failure, despite various methods of pharmacologic and/or mechanical support. Our laboratories have concentrated on the development, modification, evaluation, and validation of an ...
