In this article, we describe three cases of heart failure that did not fit the general categories of cardiomyopathy (CM), namely dilated, hypertrophic, non-dilated, non-hypertrophic types. The salient feature was non-compaction of the left ventricular (LV) myocardium on 2D echocardiography (2DE).
The normal LV myocardium is compact with scarce, inconspicuous, or no trabeculation. Trabeculae are muscular bands of the endocardium separated by spaces. The intertrabecular spaces are normally shallow or not prominent.
