[Biventricular noncompaction detected by magnetic resonance imaging: a case report]

Abstract

We report a case of biventricular noncompaction in whom magnetic resonance imaging revealed prominent trabeculations in the right ventricle as in the left ventricle. A 58-year-old man was referred to our hospital complaining of appetite loss and leg edema. Chest radiography showed cardiomegaly without pulmonary congestion. The diagnosis was right ventricular heart failure with congestive liver causing elevated liver enzyme. Transthoracic echocardiography showed prominent trabeculations and deep recesses in the inferolateral wall and apex of the left ventricle with the end-diastolic dimension of 64mm and ejection fraction of 29%. Magnetic resonance imaging demonstrated right ventricular noncompaction which remained unclear on echocardiography. Prominent trabeculations in the dilated right ventricle were confirmed by right ventriculography. The ejection fraction was 23%.
