Modified method for Novacor left ventricular assist device implantation.

We have developed and applied in 7 cases an alternative "orthodromic" technique for Novacor left ventricular assist device implantation. After sternotomy, the pocket is tailored, dividing the insertion of the diaphragm to the lower ribs, for easier bleeding control. On cardiopulmonary bypass, the aorta is cross-clamped and cardioplegia administered. Apical cannulation is performed first on a dry, still field. The device is then easily deaired, with blood flowing in the physiologic direction. The aorta is declamped and the outflow conduit is anastomosed. Before the suture is tied, the final deairing is obtained. This technique allows extreme precision in apical cannulation, easier control of bleeding, and accurate deairing of the pump. The ischemic time is short and damage to the right ventricle negligible.
