Abstract
Patients with myocardial infarction and cardiogenic shock have a massive loss of left ventricular (LV) mass. Most of these patients do poorly even with coronary revasculization and IABP support. Infarctectomy is of value when resection is limited, but resection of large area of LV result in significant reduction of LV volume and LV performance. In two series of dog experiments, our results demonstrated that this device has beneficial effects not only in the hemodynamic improvement but also myocardial metabolism recovery in the ischemic failing heart.
