Left ventricular assist system

Abstract The purpose of this study was to examine the clinical results of current circulatory support with step-by evaluation of biventricular and pulmonary function. Six patients who had undergone cardiac surgery and two non-cardiotomy patients underwent current circulatory support with the step-by functional evaluation. Of six postcardiotomy patients, four patients with severe ischemic heart disease underwent coronary artery bypass giafting (CABG), and the remaining two patients with advanced aortic stenosis underwent aortic valve replacement (AVR). All six patients received intra-aortic balloon pump (IABP) support before or during operation. Two non-cardiotomy patients suffered from dilated cardiomyopathy, and both showed acute deterioration with cardiogenic shock or low cardiac output syndrome. Three of six postcardiotomy patients with circulatory support were weaned and discharged from the hospital. Two noncardiotomy patients in critical condition were successfully supported for more than 6 months by the Novacor left ventricular assist system (LVAS). We conclude that the ongoing current strategy of circulatory support with step-by functional evaluation might be applied for various types of severe heart failure with or without associated cardiac operations.
