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).
