Abstract
Introduction
Newborns with complex congenital heart disease (CCCHD) are at high risk of neurodevelopmental disorders of multifactorial aetiology, including brain immaturity comparable to moderately pre-term infants. Nearly one third of children with CCCHD have a language delay, which negatively impacts their academic performance, communication, and social interactions.
Objective
Our team has shown that moderate preterm newborns have impaired cortical encoding of vowels compared to term newborns. Newborns with CCCHD may have a similar early encoding profile to preterm infants, which might serve as an early functional biomarker of language delay in this population.
Methods
We recruited 15 newborns with CCHD, between March and December 2022 within the department of Paediatric Cardiology in La Timone Children's Hospital. These neonates were passively exposed to a sequence of syllables using an earpiece, while cortical and subcortical event-related potentials were simultaneously recorded.
Results/Expected results
CCCHD newborns had a significantly longer neural conduction time between the cochlea and the first brainstem relay (inferior colliculus), compared with term newborns. We hypothesize that the amplitude of cortical event-related potentials will be lower in newborns with CCCHD compared to term newborns.
Conclusion/Perspectives
This altered encoding pattern is likely to be caused by immature auditory pathways. Thus, the detection of early alteration of perception could help to identify newborns at risk of language delay, allowing the implementation of targeted rehabilitation before the onset of speech disorder.
期刊介绍:
Archives of Cardiovascular Diseases Supplements is the official journal of the French Society of Cardiology. The journal publishes original peer-reviewed clinical and research articles, epidemiological studies, new methodological clinical approaches, review articles, editorials, and Images in cardiovascular medicine. The topics covered include coronary artery and valve diseases, interventional and pediatric cardiology, cardiovascular surgery, cardiomyopathy and heart failure, arrhythmias and stimulation, cardiovascular imaging, vascular medicine and hypertension, epidemiology and risk factors, and large multicenter studies. Additionally, Archives of Cardiovascular Diseases also publishes abstracts of papers presented at the annual sessions of the Journées Européennes de la Société Française de Cardiologie and the guidelines edited by the French Society of Cardiology.
