We describe a modified implantation technique for the HeartWare ventricular assist device. We access the apex through a left minithoracotomy. The outflow graft is tunneled through a small incision in the fourth intercostal space and then subcutaneously to the subclavian region. After division of the left axillary artery, an end-to-end anastomosis is performed to the proximal part, and the distal vessel is connected end-to-side through a fenestration in the outflow graft. We believe that this technique, particularly suitable for redo scenarios or severely calcified aorta, achieves a more direct blood flow into the aorta and reduces cerebrovascular events while avoiding excessive flow to the arm.

Abstract
We describe a modified implantation technique for the HeartWare ventricular assist device. We access the apex through a left minithoracotomy. The outflow graft is tunneled through a small incision in the fourth intercostal space and then subcutaneously to the subclavian region. After division of the left axillary artery, an end-to-end anastomosis is performed to the proximal part, and the distal vessel is connected end-to-side through a fenestration in the outflow graft. We believe that this technique, particularly suitable for redo scenarios or severely calcified aorta, achieves a more direct blood flow into the aorta and reduces cerebrovascular events while avoiding excessive flow to the arm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
