OBJECTIVE: Infants with congenital heart disease having obstruction to the left ventricular outflow and ductal-dependent systemic circulation can present critically ill with shock. Prompt disease recognition and initiation of prostaglandins are necessary to prevent excess morbidity and mortality. We assessed a large cohort of newborn infants with ductal-dependent systemic circulation to determine if B-type natriuretic peptide (BNP) is consistently elevated at presentation, potentially aiding in diagnosis and treatment. METHODS: The clinical records of infants with left-sided obstructive lesions admitted from January 2005 to June 2009 were reviewed. Infants were divided into 2 groups: group 1 was diagnosed with cardiogenic/circulatory shock at presentation, and group 2 consisted of infants with ductal-dependent systemic circulation without evidence of shock. B-type natriuretic peptide levels and other variables between the groups were compared. RESULTS: All patients with critical congenital heart disease presenting with shock had elevated BNP levels, ranging from 553 to greater than 5000 pg/mL. Infants in group 1 (shock, n = 36) had significantly higher median BNP levels of 4100 pg/mL at presentation compared with group 2 patients (no shock, n = 86), who had a median BNP of 656 pg/mL (range, 30-3930 pg/mL; P < 0.001). Every 100 U of increase in BNP at presentation increased the likelihood of shock (odds ratio, 100; P < 0.001). CONCLUSIONS: B-type natriuretic peptide is markedly elevated in neonates presenting in shock secondary to left-sided obstructive heart disease and is an important diagnostic tool to aid in the rapid identification and treatment of these patients.
