The David procedure in different valve pathologies: a single-center experience in 236 patients.

Background: Reports of the long-term outcome after the David procedure in different valve pathologies are limited. We compared our results in patients with tricuspid and bicuspid aortic valves, including those who required additional cusp repair.

Methods: Between 1997 and 2011, 236 patients (76% males; mean age, 56 ± 15; range, 12 to 79 years) underwent valve-sparing aortic root replacement (David procedure) for aortic regurgitation and were prospectively followed up clinically and echocardiographically.
