PERCUTANEOUS TRANSLUMINAL ANGIOPLASTY OF ANOMALOUS RIGHT CORONARY-ARTERY ARISING FROM THE ASCENDING THORACIC AORTA

Coronary arteries with anomalous aortic origin are infrequently encoun tered in patients undergoing cardiac catheterization and pose potentia l technical difficulties for performing both diagnostic and angioplast y 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 dat e, the anomalous vessel arose from the left sinus of Valsalva. We repo rt a case of a technically straightforward PTCA performed in an anomal ous RCA arising from the anterior aspect of the ascending thoracic aor ta (C) 1994 Wiley-Liss, Inc.
