Abstract

Case summary highlights a rare congenital coronary anomaly where a woman, aged 55 having diabetes as well as hypertension presented with unstable angina. Her coronary angiogram revealed Single coronary artery (SCA) originating from right coronary sinus (CS), with Left anterior descending artery (LAD) arising from Right coronary artery (RCA). Left anterior descending artery had pre-pulmonic course and showed diffuse stenosis and calcification. Off-pump coronary artery bypass grafting was performed due to significant calcification and stenosis in the coronary branches.

Keywords: Single coronary artery; Coronary artery anomalies; Pre pulmonic LAD; Coronary angiogram; Off-Pump CABG; Coronary artery disease
