Successful Challenging Percutaneous Coronary Interventions in Two Patients with Anomalous Left Coronary Artery Origin from the Right Sinus of Valsalva

Abstract

Congenital anomalies of the coronary arteries affect about 1.3% of individuals. One of the most commonly encountered anomalies involves the anomalous origination of a coronary artery from the opposite sinus of Valsalva. The incidence of ectopic left coronary artery arising from the right sinus of Valsalva was found between 0.017-0.15% in coronary angiography and autopsy series. Catheter-based revascularization of anomalous artery is a therapeutic challenge and needs experience. In this case report, we demonstrated successful percutaneous coronary interventions to anomalous left main coronary artery osteal lesion and proximal lesion in anomalous left anterior descending artery in two patients with anomalous left coronary artery origin from right sinus of Valsalva. © 2013 OMU.
