Abstract
Acute ST elevation in the anterior precordial leads typically suggests an anteroseptal infarction due to left anterior descending coronary artery obstruction, but the differential can be broad. Conus branch artery occlusion is a potentially overlooked cause of anteroseptal ST elevation myocardial infraction. Cardiac magnetic resonance (CMR) imaging is an emerging technology which can differentiate the etiology of anterior ST elevation in patients with no apparent coronary abnormalities on coronary angiography and normal echocardiography.
