Abstract Noncompaction of the ventricular myocardium is a rare congenital cardiomyopathy resulting from an arrest in normal endomyocardial embryogenesis. The characteristic echocardiographic findings consist of multiple, prominent myocardial trabeculations and deep intertrabecular recesses communicating with the left ventricular cavity. The disease uniformly affects the left ventricle, with or without concomitant right ventricular involvement, and results in systolic and diastolic ventricular dysfunction and clinical heart failure. Noncompaction was initially described in children. However, recent studies have characterized this disease in the adult population, in whom this process may be more prevalent than currently appreciated. We describe an illustrative case of isolated noncompaction of the ventricular myocardium in a 57-year-old woman with the typical clinical and echocardiographic features of the disease. The literature on the topic is reviewed.
