Insulin\u2010like growth factor\u20101 (IGF\u20101) and insulin\u2010like growth factor binding protein\u20103 (IGFBP\u20103) are essential contributors to brain growth and maturation.

The study cohort comprised term neonates diagnosed prenatally with a severe cardiac defect on ultrasound, for which surgical repair within the first month after birth was anticipated. IGF\u20101 and IGFBP\u20103 levels were measured from cord blood samples obtained directly after birth in term neonates with CCHD and healthy control neonates. All cases were stratified into two subgroups according to the predicted cerebral oxygen delivery (COD)\n                      <jats:italic>in utero<\/jats:italic>\n                      (i.e. normal or lower), based on the expected impact of the cardiac diagnosis on COD.
