RESUMO
We report an unusual case of a 22-year-old male who was incidentally diagnosed with isolated noncompaction of the left ventricle (LV) when he was admitted with viral myocarditis. Left ventricular noncompaction (LVNC) is a congenital cardiomyopathy which presents with ventricular dysfunction, cardioembolic manifestations or with arrhythmias. A diagnosis can be made with the commonly available modality of echocardiography but is still often overlooked. There is no specific treatment directed at isolated noncompaction. Treatment is focused on the cause of presentation, with medication aimed at improving ventricular dysfunction, as well as treating and preventing thrombosis and arrhythmia. This is, we feel, the first case report of isolated LVNC presenting with viral myocarditis.
