Percutaneous Coronary Intervention For Treatment of Unusual Origin of the Left Main Artery: A Case Report

Abstract

The left main coronary artery originating from the right sinus of Valsalva is a rare congenital anomaly. A 62-year-old male came in with recurring exertional chest discomfort, as observed by the authors. He was referred to the catheterisation laboratory for coronary angiography, which revealed the presence of a left main coronary artery coming from the right coronary sinus. In the proximal portion of the left anterior ascending coronary artery, a critical stenotic lesion was identified. The cardiac CT angiography demonstrated a benign retroaortic course. The lesion was effectively treated utilising three drug-eluting stents.
