Use of Computed Tomography in Preoperative Planning for Heartware Left Ventricular Assist Device Placement.

ABSTRACT

Optimal left ventricular assist device (LVAD) cannula position is important for adequate ventricular unloading and LVAD function. Poor inflow cannula position predisposes to pump thrombosis, inotrope dependence, and mortality. We describe a novel technique of preoperative left ventricular apex marking using CT guidance and demonstrate in three cases the use of this method to achieve optimal inflow cannula positioning for lateral thoracotomy Heartware LVAD implantation.
