Endomyocardial fibrosis in Sudan: clinical and echocardiographic features

چکیده
OBJECTIVE Endomyocardial fibrosis (EMF) is a rare disease and is often an underdiagnosed and forgotten cardiomyopathy. The objective of this study was to document the current frequency of EMF in Sudan by defining and selecting cases from patients attending the echocardiography laboratory. Additionally we aimed to create an EMF registry for Sudan. METHODS The study started in January 2007 and is on-going. All the patients attending our echocardiography clinics in four different hospitals in Khartoum, Sudan, were included. Transthoracic echocardiography was used as the main diagnostic and selection tool. The diagnosis of EMF was based on predefined criteria and definitions, and was further supported by additional clinical, ECG, laboratory and chest X-ray findings. RESULTS Out of 4 332 cases studied, 23 (0.5%) were found to have features of EMF. Females constituted 52% and the age range was 24 to 67 years. All patients presented with dyspnoea grades III-IV. Advanced heart failure with gross fluid overload was seen in 54% of cases and ascites was seen in 30%. EMF was biventricular in 53%, left ventricular in 29% and right ventricular in 18% of cases. Apical and ventricular wall fibrosis was found in all cases, followed by atrial enlargement, atrioventricular valve incompetence, ventricular cavity obliteration, restrictive flow pattern and pericardial effusion. Additional echocardiographic features are defined and discussed. CONCLUSION Although a rare disease, cases of EMF can be identified in Sudan if a high index of suspicion is observed. New echocardiographic features of ventricular wall layering, endocardial fibrous shelf and endomyocardiopericarial fibrosis were identified and are discussed.

M-mode echocardiographic findings are described in 21 patients with endomyocardial fibrosis. Features associated with right ventricular endomyocardial fibrosis include: (i) exaggerated motion and thickening of the anterior right ventricular wall; (ii) increased right ventricular end-diastolic dimension; and (iii) paradoxical septal motion. Pericardial effusion (viz an echo-free space behind the...
متن کاملEndomyocardial Fibrosis: Echocardiographic Profile
Evolution of two-dimensional and color Doppler echocardiography identified the typical features of Endomyocardial Fibrosis (EMF) such as dense ventricular apical fibrosis, dysfunction of atrioventricular valve and sub-valvular apparatus and cavity dimensions. This is the tool used most for the diagnosis of EMF in areas where the disease is endemic in Africa. Today echocardiography is used as a ...

Echocardiographic investigations on patients with hypertrophic cardiomyopathy with obstruction have been detailed and compared with the changes found in sixty patients with chronic Chagas' 'cardiomyopathy'. These changes are similar to those encountered in congestive cardiomyopathy. Endomyocardial fibrosis is rare in Venezuela, but six patients have been found in that country and the echocardio...
