Infective endocarditis in South African children.

The clinical and laboratory findings in 29 children with infective endocarditis over the past 10 years are reviewed retrospectively. Twenty children (70 per cent) had congenital heart disease, five (16 per cent) had rheumatic heart disease, and four (14 per cent) had no underlying cardiac abnormality prior to presentation. Twelve (41 per cent) patients had undergone cardiac surgery prior to developing endocarditis. The most common causative organisms were Staphylococcus aureus, Staphylococcus epidermidis, and viridans streptococci none of which was associated with a significantly greater mortality. There was a high case fatality rate of 35 per cent of children below the age of 6 months and children without an underlying cardiac abnormality were particularly at risk. There is a need for standardization of diagnostic criteria for infective endocarditis to facilitate accurate collaborative epidemiological investigation.
