Myocardial necrosis in both left and right ventricles detected by delayed-enhanced magnetic resonance imaging in a patient with isolated noncompaction of the ventricular myocardium.

A 58-year-old man presented with left ventricular failure. Coronary angiography revealed normal coronary arteries and endomyocardial biopsy from the right ventricular apex was normal. Echocardiogram showed marked trabeculation and deep intertrabecular recesses most prominent in the left ventricular apex, anterior and the lateral wall. Cine magnetic resonance imaging showed double-layered appearance on long-axis, 4-chamber and short-axis views. These findings were consistent with isolated noncompaction of the ventricular myocardium (INVM). Gadolinium-diethylenetriomine pentaacetic acid-enhanced imaging revealed delayed enhancement in the both left and right ventricular myocardium.
