Figure 1. Noncompaction cardiomyopathy–gross pathology in twin B.

Figure 1

In the short axis (panel A) the left ventricle shows excessive trabeculation in the anterior and inferiolateral regions of the free wall (arrows). At these points, the trabecular layer occupies more than 50% of the wall thickness. Viewed from the apex (panel B), the left ventricular outlet shows endocardial fibroelastosis (long arrow). Two of the 3 thick semilunar leaflets comprising the dysplastic aortic valve (short arrow) are visible.
