A rare coronary artery anomaly: Left main coronary artery arises from right coronary artery

Abstract

The angiographic incidence of coronary anomalies is 0.3-1%. In angiographic series, the incidence of anomalies of the left main coronary artery originating from the right sinus of Valsalva is very low. Relatively few of these patients develop symptoms such as angina pectoris, arrhythmias, syncope, myocardial infarction, or sudden death. We presented an unusual case of a patient with the left main coronary artery anomalously originating from the right sinus of Valsalva.
