Neurobehavioral assessment of children presenting diverse congenital cardiopathologies

Area of Science:

• Pediatric Neurology
• Cardiology
• Developmental Psychology

Background:

• Congenital heart disease (CHD) is a common birth defect.
• The impact of CHD on neurodevelopment, particularly brain maturation and psychomotor skills, requires further investigation.
• Early assessment of psychomotor development is crucial for children with CHD.

Purpose of the Study:

• To assess brain maturation and psychomotor development in infants and young children with congenital cardiopathologies.
• To compare psychomotor performance between children with simple (CpS) and complex (CpC) congenital heart disease and healthy controls (C).
• To identify potential links between cardiovascular status and neurodevelopmental outcomes.

Main Methods:

• A cohort of 65 children aged 1-36 months with congenital cardiopathologies was studied.
• The Rogers' test was used to evaluate psychomotor development.
• Statistical analyses included Kruskal-Wallis and Mann-Whitney tests to compare group differences.

Main Results:

• Children with complex congenital heart disease (CpC) scored significantly lower on all psychomotor variables compared to the control group (C).
• Children with simple congenital heart disease (CpS) demonstrated psychomotor performance comparable to the control group (C).
• A higher proportion of CpC children exhibited "low" psychomotor performance compared to C children.

Conclusions:

• Complex congenital heart disease is associated with significantly impaired psychomotor development in young children.
• Compromised hemodynamics and subclinical cerebral developmental immaturity likely contribute to suboptimal psychomotor performance in CpC.
• Simple congenital heart disease does not appear to significantly affect psychomotor development in this age group.
