Abstract

The Impella Recover left direct (LD) is a new intravascular microaxial blood pump, intended as a short-term mechanical support especially in case of acutely reduced left ventricular function. From September 2002 to October 2004, Impella was used to support 12 patients: six patients were supported as bridge-to-heart transplant (HTx); three patients were treated for fulminant acute myocarditis, and three patients for postcardiotomy low-output syndrome. Mean support time was 8.8 ± 2.3 days. Overall mortality was 50%. Four patients were successfully HTxed; two patients supported as bridge-to-HTx died on left ventricular assist device. Two patients with myocarditis died of septic shock; two patients in the group of postcardiotomy died of multiorgan failure. The latter two patients were slowly weaned from the device, and at 3-months follow-up showed good improvement of the left ventricular function. Our initial experience with Impella Recover LD as mechanical support for patients in cardiogenic shock of various etiology is promising, yielding a good survival in a population of particularly compromised patients.
