An intramural left main coronary artery with a left sinus of valsalva aneurysm: a unique combination of congenital anomalies.

The congenital anomaly of an intramural left main coronary artery arising in the anatomically correct aortic sinus is very infrequent. Aneurysms involving the sinus of Valsalva rarely arise from the left aortic sinus. We present the clinical features and surgical correction of this rare anomaly along with a short discussion of these congenital malformations.
