Acute coronary syndrome caused by anomalous origin of the right coronary artery from the left sinus of Valsalva.

An anomalous origin of right coronary artery from the left sinus of Valsalva is a rare congenital anomaly of the coronary arteries. We describe a 40-year-old male hypertensive and hyperlipidemic patient who presented with typical anginal pain with normal ECG and echocardiogram and abnormal exercise ECG Test Coronary angiography showed an anomalous origin of the right coronary artery from the left sinus of Valsalva, an anomaly that has been associated with angina, myocardial infarction and sudden cardiac death. The clinical profile of this congenital anomaly is also reviewed.
