OBJECTIVE: To analyze the importance of symptoms as a reason for referral to pediatric cardiologists in the diagnosis of congenital heart diseases (CHD) in the newborn (NB). METHODS: Prospective study on live NB referred for cardiac evaluation, with performance of electrocardiogram, chest radiography and echocardiography. Cardiology consultation was requested by means of a multiple-choice form including signs and symptoms suggestive of CHD. Patent ductus arteriosus (PDA) without clinical and/or hemodynamic consequences was not considered a heart disease. RESULTS: From 1999 to 2002, 358 out of 3716 NB were studied, and 49 cases of CHD and 128 of PDA were found. The prevalence of CHD was 13.2:1000 NB. The main reason for referral to the cardiologist was heart murmur in 256 (72%) NB, of which 39 (15%) had CHD, and in 91% of the 128 cases of PDA. In 14 (4%) NB, the reason for referral was cyanosis, and eight of these patients (57%) had a CHD. Heart failure was the reason for referral in 37 (10%) NB, of whom 17 (46%) had CHD. Arrhythmia, associated congenital malformations, or chromosome disorders were the reasons for referral in 14% of the cases. CONCLUSION: The main reason for referral was detection of a heart murmur on cardiac auscultation. Although cyanosis and heart failure were uncommon reasons for referral, their presence indicated a high probability of the diagnosis of heart disease. Pediatric screening plays a key role in this diagnosis.
