BACKGROUND: Rheumatic heart disease is one of the commonest causes of heart disease in Nigeria. Previous studies on rheumatic heart disease in Nigeria were either clinical or retrospective echocardiographic studies. This study was aimed at determining the burden of chronic rheumatic mitral valve disease, pattern of valvular involvement, severity and associated valvular lesions, using echocardiography. PATIENTS AND METHODS: Between May, 2004 and April 2005, patients with symptomatic rheumatic heart disease, seen in the cardiac clinics of University of Nigeria Teaching Hospital, Enugu, were recruited for the study. The patients were investigated non-invasively with M-mode, Two-dimensional, Pulsed wave, Continuous wave and colour flow Doppler echocardiographic techniques in order to assess the mitral and other intracardiac valves for evidence of rheumatic heart disease. RESULTS: There were a total of 55 patients, 39 (70.9%) females and 16 (29.1%) males with a mean age of 29.34 +/- 11.57 years. Mitral valve disease was found in 54 (98.2%) and isolated aortic valve disease in 1 (1.8%) of cases. Mitral regurgitation occurred in 64.8%, mixed mitral valve disease in 25.9% and pure mitral stenosis in 9.3%. Mitral valve disease was associated with aortic valve disease in 33.3%, with tricuspid valve disease in 24.1% and with functional pulmonary incompetence in 9.3% of cases. CONCLUSION: Rheumatic heart disease in Nigeria is essentially a disease of the mitral valve as seen elsewhere in the world. Echocardiography should be done routinely for patients with rheumatic heart disease to facilitate accurate diagnosis and definitive treatment.
