[Anomalous left coronary artery from the right sinus of Valsalva associated with coronary atheromatosis].

Anomalous origin of the left coronary artery from the right sinus of Valsalva is an anatomical abnormality that is usually associated with myocardial ischemia and sudden death. Although this abnormality may coexist with obstructive atherosclerotic coronary disease, disease is not usually found in the anomalous course of the artery. When this coronary anomaly and obstructive coronary disease are both present, it is difficult to determine the cause of ischemic symptoms.
