title: Split right coronary artery: a report of two cases.
abstract: Split right coronary artery (RCA) is a congenital anomaly of the coronary arteries where either two separate arteries arise from the aortic trunk or RCA bifurcates into two major arteries immediately after its origin from the right sinus of Valsalva. We present two cases (59-year-old male, 50-year-old female) who sought treatment for exercise-induced angina pectoris. Coronary angiography revealed a split RCA in both cases. In the first case, the RCA consisted of two well-developed arteries bifurcating immediately after its origin from the sinus of Valsalva. In the second case, the RCA split from adjacent ostia into two major arteries almost identical in size. In both cases, the split RCAs had a parallel course. Both patients were scheduled to receive medical treatment and had an uneventful follow-up of 15 and 11 months, respectively.
