An anomalous aortic origin of coronary artery is a cause of sudden death in young people. We report a surgical case of an anomalous aortic origin of the left coronary artery. A 16-year-old man with chest pain, which occurred while playing football, was taken in an ambulance. Electrocardiogram (ECG) revealed an ST-segment elevation in V1-V5. We performed coronary angiogram (CAG) and detected the anomalous aortic origin of left anterior descending artery. The computer tomography( CT) angiography revealed the intramural pathway of the left coronary artery. Surgery performed as an unroofing procedure for releasing the intramural portion of the left coronary artery. We confirmed a dilation of the left coronary artery ostia in postoperative coronary CT angiography. He did not have chest pain and other symptoms while cardiopulmonary exercise testing. He was discharged on the 18th postoperative day. He is seen as an outpatient without any symptoms.
