Sternotomy Sparing Thoratec HeartMate 3 Implantation Via Bilateral Minithoracotomy.

A novel sternotomy sparing implantation technique for the Thoratec HeartMate 3 is described. Cannulation of the left ventricular apex is performed via a minithoracotomy in the left fourth or fifth intercostal space. The outflow graft is advanced through the pericardium to a second minithoracotomy in the right second intercostal space and then anastomosed to the ascending aorta. This approach was performed in three patients so far with no need for conversion. We did not observe any perioperative adverse events, such as bleeding or thromboembolic complications, as well as no short-term mortality. This technique is especially appealing in multimorbid and frail patients, future transplant candidates, and patients with impaired right ventricular function.
