Multivessel angioplasty in a rare case of single coronary artery

Abstract

Single coronary artery (SCA) is a rare anomaly with an incidence of 0.01%–0.004% in general population. We present a rare case of SCA, which is L1 subtype of Lipton's classification of SCA, and accounts for only 0.016% of the population undergoing coronary angiogram. The patient presented with acute inferior myocardial infarction, on further evaluation she was found to have SCA. The right coronary artery was arising as a branch from the proximal left anterior descending artery (LAD) with distal LAD continuing as posterior descending artery and posterior left ventricular branch, and with a critical stenosis in left circumflex artery and LAD. She underwent successful multivessel angioplasty with good results.
