Autologous repair of "very asymmetric" bicuspid aortic valves using geometric ring annuloplasty.

Abstract

Repair of regurgitant bicuspid aortic valves (BAVs) can yield good long-term results and achieve excellent long-term survival.1-3 Favorable results stem from in-depth understanding of BAV anatomy and function. A repair-oriented anatomical classification of BAV has been presented: type A—symmetrical valve with commissural orientation of 180° to 160°; type B—asymmetrical BAV with commissural orientation of 159° to 140°; and type C—“very asymmetrical” BAV with commissural orientation of 139° to 120°.
