This report describes clinical profiles and echocardiographic, hemodynamic, and histologic findings in 26 cases of idiopathic RCM based on the diagnostic criteria of (1) heart failure resulting from a stiff left ventricle, (2) normal LV size and systolic function, (3) absence of LV hypertrophy, and (4) cause or association unknown. There were 14 male and 12 female patients ranging in age from 5 to 63 years. Ten patients died during the mean follow-up period of 145 months, and five died of heart failure after 10 years. Three had a family history of HCM. Thromboembolism was observed in eight. Echocardiograms showed normal LV wall thickness and contraction. Hemodynamic characteristics included elevated biventricular filling pressures and a pulmonary wedge pressure that was usually higher than the right atrial pressure. Equalization of biventricular filling pressures was seen, however, in almost all patients with severe tricuspid regurgitation (seven of eight). The square root sign was seen in 50% in RV diastolic pressure tracings and 28% in LV tracings. This sign was observed in patients with elevated filling pressures. Interstitial fibrosis (22 of 23), endocardial thickening (13 of 23), and myofibrillar hypertrophy (10 of 23) were common histologic findings. Severe myocardial fiber disarray consistent with HCM was seen in four patients.
