“…Endomyocardial fibrosis occurs in mainly three forms: biventricular involvement (55% of cases), followed by pure right ventricular and, rarely, pure left ventricular involvement [9]. The pathological hallmark of EMF is focal or diffuse endocardial thickening of the ventricular apices and/or the atrioventricular valves, seen as echo brightness of the endocardial surfaces, with resultant restrictive physiology and atrioventricular valve regurgitation [34]. Echocardiography may further reveal gross atrial dilatation, intramural or free thrombi, varying degrees of mitral and tricuspid regurgitation, retracted ventricles with cavity obliteration, evidence of secondary pulmonary hypertension, and sometimes large chronic pericardial effusions (Figure 4) [9,34].…”
