A case of spongy myocardium initially manifested by ventricular tachycardia in adult / 대한내과학회지

ABSTRACT

Isolated noncompaction of ventricular myocardium, sometimes referred to as spongy myocardium, is a rare congenital cardiomyopathy. Spongy myocardium results from an arrest in normal endomyocardial embryogenesis. The clinical symptoms and electrocardiographic findings of this disorder can be showed variously. The diagnosis is usually made by echocardiography. We report a case of isolated noncompaction of the ventricular myocardium in a 20-year-old male patient initially presented with syncope caused by ventricular tachycardia, who was diagnosed with echocardiography, cardiac MRI and endomyocardial biopsy.
