The Ventricular Assist Devices (V A D) have been used to maintain the cardiocirculatory conditions in patients waiting for a heart transplantation (bridge to transplant) or in patients with an acute myocardial failure during a period enough to allow a myocardial recovery. The Pierce-Donachy System (Thoratec Laboratories Corporation) is one of those devices, a pulsatile flow model, pneumatic, external, used as uni or biventricular support. The training program for different groups of surgeons, phisicians, nurses and thecnicians is difficult in many situations, mainly when it is necessary to repeat those experiences several times to permit to those groups to be more familiar with the equipment. The authors developed an experimental model (utilizing a bovine heart and an arterial pump for extracorporeal circulation) to allow a simplified way of training, analising surgical aspects, use of the drive console and simulating clinical and emergencies situations
