Developmental language trajectories in children with critical CHD

Area of Science:

• Pediatric Cardiology
• Developmental Pediatrics
• Neurodevelopmental Disabilities

Background:

• Medical advancements yield high survival rates (95%) for children with congenital heart disease (CHD).
• CHD survivors face disproportionate neurodevelopmental disabilities, including behavioral issues in toddlerhood.
• Early language delay is linked to behavioral problems, suggesting potential language deficits in critical CHD.

Purpose of the Study:

• To test the hypothesis that children with critical CHD exhibit early, detectable language deficits.
• To visualize the early language developmental trajectories of infants and toddlers with critical CHD.

Main Methods:

• Retrospective study of 27 children with critical CHD (single ventricle physiology or transposition of the great arteries).
• Utilized serial developmental evaluations, specifically the language subsection of the Capute Scales.
• Analyzed developmental language trajectories and employed linear regression for diagnosis-specific age equivalents.

Main Results:

• Language development was age-appropriate during infancy for both diagnostic groups.
• A deviation from age-appropriate language development became apparent around 18 months of age.
• Borderline to mild language delay was observed by 30 months in the studied cohort.

Conclusions:

• Quantified early language development in infants and toddlers with critical CHD using the Capute Scales.
• Identified a deceleration in language skill acquisition, supporting the need for ongoing neurodevelopmental surveillance.
• Understanding these early language patterns aids clinicians in providing informed guidance to families of children with critical CHD.
