Infective endocarditis in children: clinical analyses and evaluation of two diagnostic criteria.

A new diagnostic schema for infective endocarditis (IE), the Duke criteria, has been compared with the previously published criteria of von Reyn in adult patients. This study was designed to analyze the clinical characteristics of a group of pediatric patients with IE and to compare the diagnostic efficiency of both sets of criteria. We reviewed retrospectively the clinical records of 38 patients, 22 with predisposing heart disease (Subgroup A) and 16 with no known cardiologic abnormality (Subgroup B).
