Abstract
This report highlights a coronary artery anomaly (CAA) involving three right coronary arteries (RCAs) arising from the anterior aortic sinus and a single left coronary artery (LCA) from the left posterior aortic sinus. Furthermore, each of the three RCAs originated with separate ostia. The 1st RCA was the right conus artery which originated through the anterior ostium. The 2nd RCA from the middle ostium mimicked a typical RCA. The 3rd RCA that originated from the posterior ostium had an initial retro-aortic course and then ran between the ascending aorta and atria. It eventually terminated as the circumflex artery after reaching the left end of the posterior coronary sulcus. The LCA was normal anatomically except that it did not give the circumflex branch. The knowledge of this type of unusual branching pattern of the coronary artery may be useful to clinicians.
