A screening program for the purpose of estimating the prevalence rates for congenital and rheumatic heart disease was carried out among 6,311 children between the ages of 6 and 11 years. Among 165 children thus identified as requiring further study, a secondary program of examinations was carried out. The abnormalities discovered included 33 cases of congenital and 7 of rheumatic heart disease. The study revealed 29 cases of previously unrecognized cardiac abnormality but also relieved at least 15 children of a false diagnosis of heart disease. It was valuable not only in assuring some children of needed treatment but also in determining the diagnostic value of various physical findings.
