Patients with aneurysms of the aortic root often have dilatation of the aorta down to the aortic valve annulus. Successful reconstruction of this delicate area must first entail complete resection of all abnormal aortic tissue down to, and sometimes including, the aortic valve.

Successful reconstruction of this delicate area must first entail complete resection of all abnormal aortic tissue down to, and sometimes including, the aortic valve. The gold standard operation for patients with these types of aneurysms has been composite replacement of the aortic root with a one-piece component consisting of a dacron aortic graft and an aortic valve replacement, either a mechanical or biological valve. This procedure can be performed with exceptionally low morbidity and mortality; however, patients were subjected either to lifelong anticoagulation when choosing a mechanical valve or the potential need for reoperation when their biological valves failed.
