Coronary Intervention of An Anomalous Left Main Coronary Artery Arising from the Right Sinus of Valsalva Presented as Acute Coronary Syndrome

Abstract

Anomalous origin of the left coronary artery (LCA) from the right sinus of Valsalva is a rare congenital Anomaly. We report a 38 year old male presented with acute coronary syndrome (ACS). Referred to the Catheterization laboratory for Percutaneous Coronary Intervention (PCI). The coronary angiogram showed the LCA originating from the right coronary sinus. A critical stenotic lesion was observed in the shaft of the Left main coronary artery. CT coronary angiography displayed a benign retro aortic course. The lesion was treated successfully with stenting.
