The modified Bentall procedure for aortic root replacement.

The Bentall procedure is a surgical repair of an ascending aortic or aortic root aneurysm in combination with aortic valve disease. Less commonly, it is used to repair aortic dissection affecting the aortic root and valve. During the procedure, a composite aortic valve graft is used to replace the proximal ascending aorta and aortic valve. The procedure is performed through a median sternotomy during cardiopulmonary bypass. In this modification of the original procedure, coronary artery circulation is maintained by removing a full-thickness "button" of aorta surrounding the coronary ostia, making it easier to implant the proximal end of the coronary arteries into openings made in the aortic vascular graft.

Pulmonary thromboendarterectomy for thromboembolic pulmonary hypertension.

Pulmonary artery thromboendarterectomy (PTE) is a surgical procedure that offers the only cure for chronic thromboembolic pulmonary hypertension (TPH), a progressive form of secondary pulmonary hypertension. Current estimates indicate that 1% to 5% of patients who survive a pulmonary embolus will develop chronic TPH with progressively worsening pulmonary hypertension and right-sided heart failure. This bilateral procedure is performed through a sternotomy incision using cardiopulmonary bypass, profound hypothermia, and intermittent circulatory arrest with antegrade cerebral perfusion. As an alternative to lung transplantation, PTE offers patients with chronic TPH an improved quality of life.
