RESUMO
OBJECTIVE: The purpose of this study was to compare neurological development of children with cyanotic or hemodynamically impaired congenital heart disease (CHD) and healthy controls by using "Bayley Scales of Infant and Toddler Development Screening Test, Third Edition" (Bayley-III). PATIENTS: Children with CHD (n = 37) and healthy controls (n = 24) aged between 1 and 41 months who were admitted to the Department of Pediatric Cardiology at our university hospital were included. The participants were assessed using Bayley-III test. All patients had cyanotic or hemodynamically impaired CHD. Weight, height, body mass index (BMI), mid-arm circumference (MAC), triceps skinfold thickness (TSF), and head circumference (HC) were measured and standard deviation scores (SDSs) were determined. RESULTS: SDS values of weight, height, BMI, MAC, and TSF of the patients as well as HC values were significantly lower than the control group (P < .001). Compared with controls, the patients had significantly lower mean scores in all Bayley-III subscales (P < .001). We observed similar results in Bayley-III scores including the mean values of cognitive, language, and global motor scores for the CHD patients with and without cardiac surgery (P > .05). CONCLUSION: This study demonstrated that children with cyanotic or hemodynamically impaired CHD have delayed neurodevelopmental outcomes compared with healthy children as assessed using Bayley-III.
