[Anomalous origin of the right coronary artery from the left sinus of Valsalva. Apropos of 2 cases].
Anomalous origin of right coronary artery from the left sinus of Valsalva is a uncommon congenital anomaly which is difficult to demonstrate angiographically. For many years pathologists classified it as a minor anomaly of no clinical significance. It has only recently been associated with significant manifestations of myocardial ischemia. These manifestations have included acute myocardial infarction, angina pectoris, syncope, ventricular tachycardia and fibrillation, and sudden death. Two patients with this anomaly are reported. One patient had angina pectoris in the absence of significant atheromatous coronary lesions. In the second patient the aberrant origin of the right coronary artery was associated to aortic valve disease. The possible physiopathology mechanisms responsible for manifestations of myocardial ischemia in patients with this anomaly are analyzed.
