Abstract

OBJECTIVE: To determine growth and its relationship to IQ in children with congenital heart disease (CHD) undergoing cardiopulmonary bypass surgery within the first year of life.

STUDY DESIGN: Prospective single-center cohort study on 143 children (91 males) with different types of CHD (29 univentricular). Children with recognized genetic disorders were excluded. Growth (weight, height, and head circumference [HC]) was assessed at birth, before surgery, and at 1, 4, and 6 years and compared with Swiss growth charts. IQ was assessed at 6 years using standardized tests. Univariate and multivariable linear regressions were performed to determine predictors of HC and IQ at 6 years.

RESULTS: HC at birth was in the low average range (33rd percentile, P = .03), and weight (49th percentile, P = .23) and length (47th percentile, P = .06) were normal. All growth measures declined until the first surgery, with a catch-up growth until 6 years for height (44th percentile, P = .07) but not for weight (39th percentile, P = .003) or for HC (23rd percentile, P < .001). Children undergoing univentricular palliation showed poorer height growth than other types of CHD (P = .01). Median IQ at 6 years was 95 (range 50-135). Lower IQ at 6 years was independently predicted by lower HC at birth, lower socioeconomic status, older age at first bypass surgery, and longer length of intensive care unit stay.

CONCLUSIONS: Smaller HC at birth and postnatal factors are predictive of impaired intellectual abilities at school age. Early identification should alert clinicians to provide early childhood interventions to optimize developmental potential.
