The Heart of a Boy with Hypertrophic Cardiomyopathy.


A cross section of the heart (panel A) shows remarkable asymmetric septal hypertrophy (25-mm septal thickness and 7-mm thickness of the left ventricular free wall); in the center is a dark red area.
Panel B shows the anterior view of the heart. The proximal middle tract of the left anterior descending coronary artery follows a deep and long intramural course. The region of the first and second septal perforators (arteries) corresponds to the location of the myocardial bridging (covered by myocardial fibers).
