BACKGROUND: The burden of rheumatic heart disease (RHD) continues to be a major contributor to morbidity and premature death in poor and developing countries. We investigated patterns of valvular involvement in patients with RHD as observed in a large tertiary care hospital in eastern Nepal. METHODS: We retrospectively reviewed transthoracic echocardiography reports from patients diagnosed with RHD between June 1999 and February 2011. RESULTS: Among 10 860 transthoracic echocardiography studies, 1055 female and 658 male patients were diagnosed with RHD, 25.7% of the patients being below 20 years of age. Mitral regurgitation was the most common valvular lesion across all age groups irrespective of sex (n = 1321, 77.1%). Female patients were significantly older as compared to male patients at the time of presentation (32.8 ± 15.2 versus 28.5 ± 15.4 years; P < 0.001) and more commonly presented with mitral stenosis as compared to male patients (62.8 versus 51.5%; P < 0.001), with a peak between the age of 30 and 49 years. Conversely, aortic regurgitation was more common in men as compared to women (55.6 versus 48.9%; P = 0.007). Involvement of both the mitral and the aortic valve was observed in 49.8% of the patients and was more common in men as compared to women (52.7 versus 47.8%; P = 0.047). CONCLUSION: In this consecutive cohort of patients with RHD in Nepal differential patterns of valvular involvement are observed across sex and age categories.
