Clinical experience with the Hemopump.

摘要: Complications associated with surgical procedures generally required for implantation of left ventricular assist devices (LVADs) may limit them from providing adequate circulatory support patients suffering profound failure (LVF). Such problems are minimized the use Hemopump, a recently developed intraarterial LVAD. This 7 mm transvalvular axial flow blood pump is percutaneously powered by an external console flexible drive cable. Since April 1988, we have used device effectively in 12 patients. Indications application included postcardiotomy shock eight patients, acute allograft rejection two, severe one, and myocardial infarction one. The Hemopump was inserted femoral approach ascending aorta three, abdominal During first hr support, cardiac index (CI) ranged 1.14-2.98 L/min/m2, 3.0 to 3.6 L/min. As patients' hearts recovered, speed gradually reduced. Circulatory 26 139 hr; 10 were successfully weaned. mean CI before removal 2.74 +/- 0.4 2.14 0.69 No device-related infections or thromboembolic episodes occurred. Plasma-free hemoglobin remained within acceptable levels during pumping. Six survived more than 30 days after removal. Thus, can provide safe, stable, temporary be expeditiously applied minimal complications.
