Screening for neurodevelopmental disorders in children with congenital heart disease

The aim of this study was to evaluate the frequency of neurodevelopmental disorders (NDD) in children with significant congenital heart disease (CHD) and to determine associated factors to NDD and frequency of follow-up in developmental therapies. Two hundred and ten children with significant CHD aged from 6 to 66 months were enrolled over a period of six months. The Ages & Stages Questionnaire Third Edition in French (ASQ-3) was used to assess neurodevelopmental domains. NDD were defined if cut-off scores were ≤ − 1SD. – 1SD corresponded to “Monitor” range: children with minor or emerging disorders; − 2SD corresponded to “Refer” range: children exhibiting neurodevelopmental delays. Forty children were in “Monitor” range and 86 in “Refer” range. NDD rate was 60.0% (n = 126, 95% CI, 53.4 to 66.6%). There was no difference regarding CHD severity (p = 0.99). Only the presence of non-cardiac disease (OR = 2.14; 95% CI, 1.11 to 4.20) was associated with NDD. Forty-six children with NDD had no developmental follow-up (among them 21 were in “Refer” range (10%)) despite this being available.
