Background: Infective endocarditis (IE) is an important cause of child morbidity and mortality, but the current burden of the disease in Thai children is unknown.Objectives: To determine the current burden of IE in Thai children.Patients and Methods: The records of all children aged <15 years admitted to Khon Kaen University Hospital from 1992 to 2011 were reviewed.Results: Of 69,822 admissions, 56 patients fulfilled the modified Duke criteria for definite IE giving a rate of 0.8 cases per 1,000 admissions.
