An Intracorporeal (Abdominal) Left Ventricular Assist Device: Initial Clinical Trials (LX)

Chapter

Abstract

Our initial studies of partial artificial hearts in man have involved patient population analyses combined with engineering, biomaterial, surgical, cardiologic, anesthetic, hematologic, perfusion, and computer-technology applications. Unlike the intra-aortic balloon pump (IABP), which augments existing circulation, this abdominal left ventricular assist device (A-LVAD) is a true intracorporeal blood pump that can be actuated synchronously or asynchronously, independently of an intact ECG signal. It is interposed between the apex of the left ventricle and the infrarenal abdominal aorta. The hemodynamic advantages of this unique configuration in comparison with IABP and left atrial-to-systemic artery pumping are shown in Table 11.1.
