A superdominant left anterior descending artery (LAD) was found in a 59-year-old man who had electrocardiographic evidence of acute anterior and inferior wall myocardial infarction. Coronary cineangiography showed 95% stenosis at segment 7 of LAD which extended around the apex, ascending into the posterior interventricular sulcus to the crux and ran to the left into posterior atrioventricular sulcus. Posterior descending artery was not provided by the left circumflex artery or the right coronary artery. Multiple infarction due to proximal disease of such a superdominant LAD is very rare in pathoanatomically. Coronary artery bypass grafting to the LAD using left internal mammary artery was performed. The patients is now doing well with no anginal attack, 18 months following the operation.
