[Endomyocardial fibrosis: report of 22 Congolese cases].
A study has been made of 22 cases of endomyocardial fibrosis (EMF) observed over a 12-year period. The epidemiological characteristics have been described, and the importance of the echocardiographic findings in the diagnosis of the disease has been emphasized. EMF constitutes 0.3% of the total admissions in the department, 0.9% of the cases of cardiac failure, and 3% of the cases involving subjects under 40 years old. The patient population consisted of 13 men and 9 women with an average age of 35.6 +/- 16.4 years (age range: 8.5-77 years). The diagnosis of EMF was based on clinical, radiological, electrocardiographic, and echocardiographic findings (22 cases), and surgical examination (1 case). In 8 cases, parasitosis (filariasis: the patients came from a known endemic area) with hypereosinophilia was observed. Three of these patients had associated high blood pressure. In 13 subjects, a severe right adiastolic syndrome was noted. Two patients presented with tachycardia, 2 others had signs of overall cardiac failure, and 5 subjects suffered from palpitations connected with arrhythmia. Thoracic X-ray showed cardiomegaly in all cases, lung involvement in 15 cases, normal lungs in 5 cases, and bilateral hilar stasis in 2 cases. Electrocardiography mainly showed endomyocardial fibrosis (15 cases), supraventricular arrhythmia, notably auricular fibrillation (13 cases), and conductive disorders (12 cases), which were frequently associated. Echocardiography showed the presence of EMF in 21 cases (95.5%). Doppler (n = 9 cases) detected tricuspid failure in 9 subjects, and mitral failure in 1 subjects. EMF was exclusively located on the right side in 19 cases, bilateral in 2 cases, and on the left in 1 case, which required surgery. Four patients died (i.e., 1 case of sudden death, 1 case of pulmonary embolism, 1 case of neurological coma, and 1 case of cardiac arrhythmia). The authors, like many others, note the clinical polymorphism of EMF, the predisposition to the disease caused by the presence of helminthiasis, which should be eradicated, the diagnostic value of echocardiography-Doppler, and the efficiency of surgery in the treatment of this condition.
