Characteristics of patients in private pediatric cardiology unit: seven-year analysis

Background: Despite advances in the diagnosis and treatment of heart diseases during childhood, congenital heart defects remain a prominent factor in neonatal morbidity and mortality. Acquired heart diseases, such as rheumatic fever, also have high impact on public health. Knowledge of these cardiac patient profiles is thus important for focusing resources and optimizing results. Objective: To describe the main diagnostic and clinical findings for patients seen at a private pediatric cardiology center, by age bracket. Methods: We analyzed 17,873 records for patients seen during the past seven years, emphasizing: gender, age, reason for referral, the main findings in the history of the current disease, main findings from physical examinations, supplementary tests and the main diagnoses through echocardiograms. Results: There was a predominance of males (53.7%), with an average age of 63.5 months, with some 25% of the sample younger than two years of age. The main reasons for referral were cardiological reports for patients more than two years old, and suspected CHD for younger children. On physical examination, 59.8% presented anomalies, with murmurs found in 35.8%. Echocardiography was performed for 96.93% of the sample. The most frequent CHDs detected by echocardiography were left-to-right shunt lesions (62.75%).
