Background: Pulsatile left ventricular assist devices are used with increasing frequency to bridge patients with end-stage heart failure to heart transplantation (HTx). Implantation of pulsatile devices is a cumbersome surgical procedure that is associated with major complications, such as bleeding, thromboembolism, and infection. Recently, a continuous axial flow left ventricular assist device (DeBakey ventricular assist device) has been introduced with the goal of reducing the incidence of major complications.
Methods: We reviewed our experience with 11 patients who received a DeBakey ventricular assist device axial flow pump for bridge to HTx from April 2000 through November 2001.
Results: Two patients (18.2%) died of multiple-organ failure while on left ventricular assist device support. Bleeding requiring thoracotomy occurred in 2 patients (18.2%). One patient had a minor neurologic event, and one patient developed left ventricular assist device thrombosis, which was successfully treated without pump exchange. Renal failure developed in 1 patient and hepatic dysfunction in 2 patients. There were no instances of right heart failure. No device, pocket, or drive-line infections occurred. Nine patients (9 of 11, 81.8%) had HTx within 51 +/- 49 days (range, 11 to 141 days) after left ventricular assist device implant. One patient died 29 days after HTx because of acute rejection.
Conclusions: The continuous axial flow DeBakey ventricular assist device had reliable features, including a high rate of bridge to HTx. This device had low complication and system failure rates. We consider the DeBakey ventricular assist device a favorable alternative to pulsatile heart assist devices as a bridge to HTx.
