Congenital heart disease (CHD) is one of today's leading birth anomalies. Children with CHD are at risk for adaptive functioning challenges. Sleep difficulties are also common in children with CHD.

Major congenital heart disease (CHD) is associated with impaired neurodevelopment (ND), partly from prenatal insults. In this study we explore associations between 2nd and 3rd trimester umbilical (UA) and middle cerebral artery (MCA) pulsatility index (PI = systolic-diastolic velocities/mean velocity) in fetuses with major CHD and 2-year ND and growth outcomes. Eligible patients included those with a prenatal diagnosis of CHD from 2007 to 2017 without a genetic syndrome who underwent previously defined cardiac surgeries and 2-year biometric and ND assessments in our program.

Compared with those born at term gestation, infants with complex congenital heart defects (CCHD) who were delivered before 37 weeks gestational age and received neonatal open-heart surgery (OHS) have poorer neurodevelopmental outcomes in early childhood. We aimed to describe the growth, disability, functional, and neurodevelopmental outcomes in early childhood of preterm infants with CCHD after neonatal OHS. Prediction models were evaluated at various timepoints during hospitalization which could be useful in the management of these infants.

Background: Children with congenital heart disease (CHD) are at risk of adverse long-term neurodevelopmental outcomes, believed to be, in part, secondary to prenatal insults. Placental pathology and altered fetal middle cerebral arterial (MCA) flow suggestive of brain sparing have been documented in fetal CHD. In the present study we investigated the relationship between MCA and umbilical arterial (UA) flow patterns in fetal transposition of the great arteries (d-TGA) and hypoplastic left heart syndrome (HLHS) and growth and 2-year neurodevelopmental outcomes.

Background: The newest measure of neurodevelopmental outcomes, the Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III), gives higher-than-expected scores for preterm infants; results after cardiac surgery are unknown.

Objectives: The goal of this study was to report Bayley-III scores after cardiac surgery and compare the results with those of the Bayley Scales of Infant Development, 2nd Edition (BSID-II) on a subset of the same children.

Methods: In this prospective, inception cohort, neurodevelopmental outcome study after complex cardiac surgery in infants from 2004 to 2007, the Bayley-III was given to 110 survivors (68% boys) at a mean age of 21 months (SD: 4 months).
