Abstract
Isolated ventricular noncompaction (IVNC) is an unusual congenital heart disease. The morphological features are trabeculations and intertrabecular recesses within the left ventricle. Important clinical considerations include the high mortality due to depressed cardiac function, and the instance of ventricular arrhythmia and systemic embolism. One of reasons for the high mortality is that there is still no effective therapy with the exception of the recommendation for anticoagulation therapy to prevent embolisms. Hence, we describe a 29-year-old man with IVNC presenting with chronic heart failure. Careful up-titration of carvedilol in this patient changed the parameters of cardiac diastolic performance
