Technical options in repairing the diseased ascending aorta with aortic valve involvement

Operative repair of the diseased ascending aorta with aortic valve involvement consists of replacement of the ascending aorta and the aortic valve plus reconstitution of coronary arterial flow. Two basic techniques are presently available. The conventional technique involves separate replacement of the aorta and valve above and below a small segment of retained aorta including the coronary orifices. The second method consists of replacement of the entire ascending aorta and aortic valve with reconstitution of coronary flow by approximation of the coronary orifices to the Dacron conduit or with saphenous vein bypasses. Each method has its merits depending on the exact pathological anatomy encountered near the coronary orifices. Other pathological variables exist that demand additional intraoperative choices in technique. The present report details the operative repair of this lesion and outlines the technical options available for solution of the various problems encountered.
