Percutaneous coronary intervention of an anomalous right coronary artery originating from the left coronary artery

Summary Anomalous origin of the right coronary artery is a rare congenital anomaly that was first described in 1948 by White and Edwards. It is well established that an anomalous origin of the right coronary artery can lead to angina pectoris, myocardial infarction, or sudden death, in the absence of atherosclerosis. Thus from the literature data it has been also suggested that the abnormal origin and course of anomalous coronary arteries could make them more prone to atherosclerosis due to altered flow patterns. We report our experience involving one patient who had significant atherosclerotic disease and was successfully treated with percutaneous coronary intervention (PCI) and stent implantation in an anomalous right coronary artery arising from the left coronary artery.
