Abstract

BACKGROUND: Echocardiography is rapidly established itself as the primary diagnostic technique for investigation of children with heart disease, and referrals are increasing to the pediatric cardiology clinic for investigation. However, because there is a lack of analysis data on the patients referred to pediatric cardiology clinics, we have proceeded to compare and analyze their characteristics to provide basic data base.
METHODS
From Oct. 1, 1998 to Jul. 10, 1999, total 443 cases referred to the pediatric cardiology clinic of Yeungnam University Hospital were studied retrospectively by medical records, chest X-ray, EKG and echocardiography, etc.
RESULTS
The results were as follows. 1. The proportion of male was 61.0%(261 cases) and that of female was 39.0%(167 cases). The ratio of male to female was 1.6:1. The proportion infants less than 1 year-old was 62.6%(268 cases) of all patients. 2. Cardiac murmur was present in 248 cases(57.9%), which was the most common case of referral to the pediatric cardiology clinic. The impression at referral was more congenital heart disease(70.6%) than acquired heart disease(17.8%) and arrhythmia(11.6%). 3. The final diagnosis was as follows : congenital heart disease was present in 212 cases(49.5%), acquired heart disease, 59 cases(13.9%); arrhythmia, 13 cases(3.0%); normal heart, 144 cases(33.6%).
CONCLUSION
Among the patients referred to pediatric cardiology clinic, 33.6%(144 cases) had normal hearts and why these patient were referred may be possibly due to more dependence on echocardiography than on auscultation instruction. Threfore, clinical and auscultatory skill should be emphasized to minimize dependence on expensive echocardiography for evaluation of pediatric heart disease.
