Abstract


Dual left anterior descending (LAD) artery is a rare coronary anomaly. We present a patient with a rare case of dual LAD, smaller one arising from the left main coronary stem and larger one from right coronary artery who presented with acute anterior wall myocardial infarction with complete heart block (CHB). Temporary pacemaker was implanted and coronary angiogram revealed critical occlusion of proximal LAD which was subsequently revascularized by primary angioplasty using drug-eluting stent (Xience prime, 2.75 × 23 mm) leading to recovery of CHB and restoration to normal rhythm. To the best of our knowledge, this is the first reported case of dual LAD presenting with CHB treated by primary angioplasty reported in the literature.
