Common origin of both right and left coronary arteries from the right sinus of Valsalva.

Anomalous origin of the left main coronary artery (LMCA) from the right sinus of Valsalva (RSOV) represents in about 2 per 10,000 patients undergoing diagnostic cardiac catheterization. This rare anomaly correlates with sudden cardiac death after exercise and angina. We describe the case of a middle-aged woman, suffering from typical angina pectoris, with an anomalous common origin of all coronary arteries from the RSOV. We also provide the variations of the anomaly and discuss briefly on pathophysiology and treatment.
