What this trial studies

This study focuses on children aged 3 to 11 who have undergone heart surgery for critical congenital heart defects (CHD) within their first three months of life. It aims to assess the neurodevelopmental outcomes of these children, as over 50% are at risk of developing neurodevelopmental disorders (NDs). The study involves blood sampling and various assessments to evaluate neurodevelopment and parental stress, providing insights into the cognitive and behavioral challenges faced by these children. By understanding the link between CHD and NDs, the study seeks to improve care strategies for affected families.

Who should consider this trial

Good fit: Ideal candidates are children aged 3 to 11 who have had heart surgery for critical congenital heart defects within the first three months of life.

Not a fit: Patients with pre-existing genetic anomalies or malformative syndromes associated with neurodevelopmental abnormalities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better support and interventions for children with congenital heart defects and their neurodevelopmental challenges.

How similar studies have performed: Other studies have indicated a significant association between congenital heart defects and neurodevelopmental disorders, suggesting that this approach is grounded in existing research.
