Percutaneous transluminal angioplasty of anomalous right coronary artery arising from the ascending thoracic aorta

Abstract

Coronary arteries with anomalous aortic origin are infrequently encountered in patients undergoing cardiac catheterization and pose potential technical difficulties for performing both diagnostic and angioplasty procedures. Percutaneous transluminal coronary angioplasty (PTCA) of atherosclerotic disease in anomalous right coronary artery (RCA) has been described in only a few reports. In all the cases reported to date, the anomalous vessel arose from the left sinus of Valsalva. We report a case of a technically straight-forward PTCA performed in an anomalous RCA arising from the anterior aspect of the ascending thoracic aorta.
