Congenital unicuspid aortic valve repair without cusp patch augmentation.

Unicuspid aortic valves are rare congenital malformations. Surgical repair is feasible in aortic regurgitation, and in some cases of aortic stenosis. The standard surgical approach is a bicuspidization and symmetrization with pericardial patch augmentation of valve leaflets. Herein, we are describing our original technique for bicuspidization of a unicuspid aortic valve in adults without leaflet patch augmentation. We also address the surgical management of a commissural diastasis.
