An exceptional form of congenitally bicuspid aortic valve resulting in pure aortic regurgitation.

Abstract

A case with an exceptional form of congenitally bicuspid aortic valve is described. A fibrous strand connected to the supra-aortic ridge supported the conjoined cusp, and severe pure aortic regurgitation was present although the fibrous strand remained intact. Aortic valve replacement was successfully performed.
