[Pericardial disease erroneously diagnosed as endomyocardial fibrosis. Report of 2 cases].

Two patients who were sent to operation with diagnosis of endomyocardial fibrosis (EMF) turned out to have pericardial disease. EMF had been suspected on the basis of clinical history, electrocardiographic, radiologic and echocardiographic data. The hemodynamic studies were "typical", and included apex amputation, flat ventricular surface and mitral and tricuspid insufficiencies. Thus, ventriculography should not be considered specific, but rather suggestive of endomyocardial fibrosis.
