Separate Origins of All Three Major Coronary Arteries from the Right Sinus of Valsalva:A Rare Coronary Artery Anoma ly

Abstract

The origination of all three major coronary arteries from three separate ostia in the right sinus of Valsalva is an exceedingly rare coronary anomaly. Few radiographic and clinical details of this anomaly are available in the literature. We describe this anomaly in a patient with acute myocardial infarction who remained asymptomatic until the 8th decade of her life. Atherosclerotic narrowing of the normally originating right coronary artery caused the acute myocardial infarction. Anomalous left anterior descending and left circumflex arteries were free of any significant obstruction.
