Fibrosis endomiocárdica. Presentación como una tumoración ventricular derecha

Endomyocardial fibrosis is an uncommon disease in Spain, with the most frequent clinical feature being congestive heart failure syndrome. Complete atrioventricular block is exceptional. Two-dimensional echocardiography is a fundamental investigation achieving the diagnosis. Surgical treatment is recommended in symptomatic patients. We present a patient with heart failure secondary to endomyocardial fibrosis with complete atrioventricular block and an infrequent echocardiographic image of a polycystic mass in the free right ventricular wall.
