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

A 73-year-old man diagnosed with severe aortic regurgitation by transthoracic echocardiography was referred to our hospital. Quadricuspid aortic valve was diagnosed on preoperative transesophageal echocardiography. We performed aortic valve replacement with a bioprosthetic valve. In the operation, the accessory cusp was found to be located between the right coronary and noncoronary cusps, and the cusps had multiple fenestrations near the commissures.
