Background: Rheumatic heart disease (RHD) is a major public health problem in resource-poor countries. According to the World Health Organization (WHO), rheumatic fever (RF)/RHD affects about 15.6 million people worldwide, with 282,000 new cases and 233,000 deaths each year. There are about 2 million people with RHD requiring repeated hospitalization and 1 million likely to require surgery globally. Objective: The objective of the study is to explore the pattern of RHD in Abeokuta where such a study has not been reported in the past. Materials and Methods: This is an analysis of a prospectively collected data over a period of 5 years (Jan 2006-Dec 2010). We collected information on the bio-data, clinical features and echocardiographic diagnoses. Results: During this period, a total of 107 cases of RHD were seen, 66 females (61.7%) and 41 males (38.3%) aged 43.9 ± 19.3 years (range, 7 to 92 years). Mitral regurgitation was the most common lesion (63.6%). Other common lesions include pure mitral stenosis (14.0%), mixed mitral valve disease (6.5%), and mixed mitral and aortic regurgitation (5.6%). Complications of RHD observed included secondary pulmonary hypertension, valvular cardiomyopathy, atrial fibrillation, stroke and infective endocarditis. Conclusions: Our data show that RHD is an important cause of heart disease in this city although the prevalence is lower than studies done in southern Nigeria in the 60s and 70s. Most present with complications and many do not have access to surgical therapy. There is, therefore, a need for improved surveillance and control of the disease at the community level.
