Abstract

Anomalous origin of the left main coronary artery from the right sinus of Valsalva or the right coronary artery is a rare coronary anomaly. This anomaly has been associated with sudden cardiac death in younger patients, depending on its course relative to the pulmonary artery. The authors report this rare anomaly in two patients. It presented as unstable angina in the first patient with a septal course. In the second patient, it presented as syncope with an anterior free wall course and absent left circumflex artery. A septal course causing unstable angina has not been reported previously.
