Endomyocardial fibrosis of the right ventricle

Echocardiogram showing endomyocardial fibrosis, a cause of segmental abnormality of the apical region of the right ventricle (RV). In this example, the disease, which is often bilateral, is limited to the right ventricular apex. The characteristic apical obliteration (O) is shown in panel A and is highlighted (arrows) by contrast injection (C) in panel B.
