Bicuspid aortic valve stenosis with single coronary artery.

A 56-year-old female with congestive heart failure was transferred to our institution. Aortography demonstrated aortic valve stenosis (AS) with a congenitally bicuspid valve and dilatation of the ascending aorta. Preoperative coronary angiography showed a left single coronary artery. Replacement of the aortic valve and ascending aorta was performed. She had an uneventful postoperative course. We report the case of aortic bicuspid valve stenosis with single coronary artery as an extremely rare congenital cardiac anomaly combination.
