Long-term follow-up of supra-annular pulmonary autograft aortic root replacement in patients with bicuspid aortic valve.

Objective: The performance of the Ross procedure in the case of geometric mismatch between pulmonary autograft and a bicuspid aortic root has not yet been fully evaluated. To prevent geometrically caused autograft dysfunction, a modification of the surgical technique is necessary.

Methods: Between January 1996 and January 2007, 50 patients (33 male, 17 female; mean age 50+/-14 years; range 13-63 years) underwent replacement of a diseased bicuspid aortic valve (stenosis in 14 cases; insufficiency in 21; combined disease in 15) with a Ross procedure.
