A Case of Quadricuspid Aortic Valve with Aortic Regurgitation / 日本心臓血管外科学会雑誌

ABSTRACT

A 61-year-old man with aortic regurgitation was found to have a quadricuspid aortic valve during operation. The aortic valve consisted of four equal sized cusps with an accessory cusp located between the left and right coronary cusps. The right coronary ostium was placed in a lower position. Aortic replacement with a St. Jude Medical prosthesis was performed successfully. Quadricuspid aortic valve is a rare anomaly and 14 cases of quadricuspid aortic valves in the Japanese literature which were corrected surgically are reviewed.
