Origin of left main and right coronary arteries from right aortic sinus of Valsalva [5]

Coronary anomalies may be a part of complex congenital malformations of the heart or be an isolated defect. Anomalous coronary arteries are associated with a higher incidence of congenital heart diseases, but do not appear to be associated with an increased risk for development of coronary atherosclerosis. Coronary anomalies are recognized readily on angiography. Unexpected findings during invasive procedures would suggest a possibly existing coronary anomaly, especially when main branches cannot be opacified by selective contrast medium injection. This case report illustrates the clinical and angiographic findings of a patient undergoing coronary angiography for evaluation of ischemic heart disease with an unexpected presence of anomalous origin of the left coronary artery from the right aortic sinus.
