Technique for insertion of HeartMate II left ventricular assist device inflow cannula.

Abstract

During implantation of the HeartMate II left ventricular assist device, the inflow cannula is typically inserted in such a way that the sewing ring is placed within the ventricular cavity in contact with the endocardium. We describe a novel implantation technique in which the sewing ring is secured to the left ventricular epicardium, thus avoiding the complication of bleeding from the exposed cut surface of apical myocardium. In addition, the shortened intraventricular segment of the inflow cannula protects against inflow occlusion by the interventricular septum.
