Abstract
- A 57-year-old man with dyspnea was transferred to our institution. Echocardiography demonstrated grade III aortic valve regurgitation with a bicuspid aortic valve. The preoperative coronary angiography showed a left single coronary artery. Replacement of the aortic valve was performed. Ventricular fibrillation developed during weaning the patient of cardiopulmonary bypass after aortotomy repair. An anomalous origin of the coronary arteries is usually an incidental finding. However, in patients who are undergoing aortic valve replacement, a single coronary artery can significantly complicate the procedure. If this is present, then it is imperative that the precise anatomy be clearly identified and the required procedure should be modified to avoid injury to these vessels.
