Abstract

A simple left heart assist device was developed to reduce left ventricular preload while simultaneously increasing total systemic blood flow. It consists of special cannulas connected to a simple extracorporeal tubing loop and roller pump, designed to permit bypass of as much as 5 liters of blood per minute from left atrium to ascending aorta. Employed in 15 patients with advanced heart disease who were in low cardiac output following repair, the system was proven effective. An asset of the device is the ability to subsequently separate the patient from the device without need to reenter the thorax or abdomen.
