title: Single coronary artery from the right coronary sinus with proximal origin of the left anterior descending coronary artery and left circumflex as distal continuation of the right coronary artery: a rare variant.
abstract: A single coronary artery is a rare coronary anomaly. A 68-year-old male underwent coronary angiography for recent inferior wall myocardial infarction. It revealed a common coronary trunk arising from the right sinus of Valsalva and bifurcated into the right coronary artery (RCA) and anterior descending coronary arteries. The RCA, after its usual distribution in the right atrioventricular groove, continued as the left circumflex artery in the left atrioventricular groove. There were significant stenoses in the mid and distal RCA, which were treated percutaneously.
