Regional distribution of vascular supply to the ventricles with right coronary artery dominance. A. Postmortem angiogram of the heart in a patient with acute myocardial infarction with total occlusion (arrow) of the proximal left anterior descending coronary artery (LAD) in a 65 -year-old woman who presented with persistent chest pain of 6 hours' duration. B. At autopsy, she had a hemopericardium with rupture site (arrow) identified on the anterior wall of the left ventricle. Note extensive hemorrhagic (h) transmural infarction involving the anterior wall of the left ventricle near the base of the heart (upper slices) and extending into the septum in the mid and apical slices (lower slices). C. Gross photography of the LAD showing hemorrhage into the necrotic core and more than 90% luminal narrowing; barium is seen within the lumen (arrow). D.
