I believe it would interrupt blood supply to the left and right ventricles and much of the interventricular septum. Myocardial infarction (heart attack) occurs when blood flow decreases or fails to reach parts of the heart, causing damage to the heart muscle. Occlusion of the left anterior descending artery may cause infarction of the anterior wall of the left ventricle, manifested as precordial ST-segment elevations.
