[A case report of congenitally bicuspid aortic valve and ascending aortic aneurysm treated by wheat operation].

A 59-year-old man who complained of palpitation was diagnosed as having a congenitally bicuspid aortic valve, severe aortic regurgitation, and an ascending aortic aneurysm. He underwent aortic valve replacement and conduit replacement by the modified Wheat technique. Since this technique requires no coronary artery anastomosis, it causes no problems associated with reconstruction of the coronary artery. Postoperative angiogram revealed no aneurysm formation of the aortic root or paravalvular leakage. This case suggest that aneurysm of the ascending aorta with aortic regurgitation is more effectively treated by the modified Wheat technique if cephalad displacement of the coronary ostium is not extensive.
