Technical assessment of Novaoor Left ventricular Assist Device Implantation

Abstract

Novacor left ventricular assist device has been widely used as a bridge to transplantation. In this study, we made experimental implantation of Novacor LVAS using a sheep. The pit falls of experimental implantation was listed as follows; 1) positioning of the out flow and inflow conduit through the diaphragma is important for preventing the graft kinking. 2) the size of myectomy should be large as much as possible. Also position of the drainage cannula should be selected to avoid coronary injury and kinking of graft, 3) the thrombosis and debris in the device should be avoid through the implantation technique. 4) air evacuation is very important and should be perfomed as quickly as possible. These technical pit falls might be important to prevent complications.
