Congenital heart disease patients have a higher rate of developmental disorders and cognitive delay. A retrospective review was performed on CHD patients requiring cardiac surgery within the first year of life at Doernbecher Children's Hospital from 1/1/13-12/31/18. A surgical database collected patients' variables, including CHD, prenatal diagnosis, birth weight, gestational age, ND evaluation referral and results, and Early Intervention referral. Patients with a longer length of hospital stay were more likely to undergo ND evaluation (22 vs 15 days, p=0.02). While most patients with CHD had low to average scores on ND testing, single ventricle patients scored particularly low in cognitive and gross motor function. More than half of the patients who received initial testing followed-up with additional appointments in all CHD categories, demonstrating the importance of initial ND evaluation.
