The amount of fibrosis in endomyocardial biopsies from 55 patients with aortic stenosis and 42 patients with aortic regurgitaion was measured. Sixty per cent of the patients with aortic stenosis had some degree of fibrosis; the degree of fibrosis correlated strongly with ejection fraction, peak systolic gradient, symptoms of cardiac failure, and mortality. In patients with aortic regurgitation,...

A 26 year old Saudi man with features of both Loeffer's endocarditis and endomyocardial fibrosis presented with mild symptoms and pulmonary emboli. Echocardiographic examination showed obliteration of the right ventricular apex by an attached mass. The results of haemodynamic studies were somewhat abnormal and medical treatment was started. Despite anticoagulation with warfarin the patient's co...

Background Accumulation of diffuse interstitial myocardial fibrosis in severe aortic stenosis relates to left ventricular (LV) functional impairment and determines the postoperative outcome in these patients. T1 mapping has been proposed for non-invasive quantification of diffuse interstitial fibrosis. We examined associations between T1 values and collagen volume fraction from endomyocardial b...

OBJECTIVES This study was performed to determine the degree and time course over 6 years of cardiomyocyte hypertrophy and myocardial fibrosis of the cardiac allograft in transplanted patients. BACKGROUND Diastolic dysfunction and to a certain extent systolic dysfunction are common cardiac findings after heart transplantation. The development of posttransplant cardiomyocyte hypertrophy and myo...

Endomyocardial fibrosis is a relatively common form of heart disease in Uganda (Davies, 1948; Shaper and Williams, 1960) and accounts for some 10 per cent of heart disease seen at necropsy in Kampala (Davies, 1961). It is characterized in the established condition by fibrosis in the endocardium and subjacent myocardium affecting particularly the inflow tract and the apex of one or both ventricl...

A 48-year-old man from West Africa was evaluated for dyspnea. Echocardiography showed an echolucent mass at the left ventricular apex surrounded by a dense ridge of tissue, suggesting endomyocardial fibrosis (EMF). Doppler echocardiography showed restrictive hemodynamics and intramyocardial coronary blood flow at the hypertrophied apex, suggesting apical hypertrophic cardiomyopathy (ApHCM) with...
