Infective endocarditis in children: profile in a developing country.

With the object of studying the profile of infective endocarditis in Indian children younger than 16 years of age, a retrospective study of 37 patients with infective endocarditis admitted to this hospital between January 1984 and December 1990 was carried out. There were 26 boys and 11 girls (aged 2-16 years (mean (SD) 10.3 (3.8)). Eighteen (48.6%) patients had underlying congenital heart disease, 13 (35.1%) had associated rheumatic heart disease whilst the remaining six had no pre-existing heart disease. All six patients with a normal heart and infective endocarditis had preceding extra-cardiac bacterial illnesses (epididymitis and orchitis in one, pneumonia in five). Blood cultures were positive in only 16 (43.2%): Staphylococcus aureus was grown in nine, Streptococcus viridans in six and Candida albicans in one. Sixteen (43.2%) of the 37 patients died owing to worsening cardiovascular haemodynamics, uncontrolled septicaemia and our inability to offer emergency surgery. The profile of infective endocarditis in developing countries is different from that in Europe and the United States of America, and the disease carries a very high mortality.
