Single coronary artery is a rare congenital coronary artery anomaly, the incidence of which is 0.024-0.066% as described in literature. Report of cases having single coronary artery along with acute myocardial infarction are scanty and reports of percutaneous intervention in such a situation are even fewer, technically challenging and potentially cataclysmic. As single coronary artery supplies the entire myocardium, occlusion of this can result in significant ischemic insult, resulting in severe biventricular dysfunction. Percutaneous Coronary Intervention (PCI) of single coronary artery is technically challenging and carries high risk which may be equated to left main intervention. We report a rare interesting case of L1 variety of single coronary artery which presented as acute inferoposterior myocardial infarction with successful rescue PCI to Left Circumflex Artery (LCx).
