Key result
Higher IQ and maternal mental health predict normal behavior in ~55% of complex CHD children.
Why the study?
This study investigated behaviour in children with complex congenital heart disease from preschool to adolescence and identified predictors for normal behaviour.
In children with complex congenital heart disease, higher child IQ and better maternal mental health at preschool age predict normal behavioural trajectories through adolescence.
May warrant early screening of maternal mental health and child IQ in complex CHD; extends evidence on behavioral trajectories.

Ehrler et al. (2026) studied this question. Children with complex congenital heart disease showed distinct behavioral trajectories, with 55% maintaining normal behavior predicted by higher child IQ (OR=1.1) and maternal mental health (OR=0.9).
