Noncompaction of the ventricular myocardium is a rare congenital cardiomyopathy caused by arrest of normal endomyocardialembryogenesis. Isolated right ventricular noncompaction (IRNC) is an even rarer form of this disease. We report herein on a 68year-old male diagnosed with IRNC who presented with right-sided heart failure, without involvement of the left ventricle. Diagnosis was achieved with the aid of echocardiography and ventriculography. Medical treatment including prescription of diuretics,a calcium channel blocker, and digitalis, improved both the symptoms and right ventricular function.
