Heart-Brain link: major study seeks hidden causes of learning delays in children with heart defects
NCT ID NCT06442592
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow over 1,200 children aged 3 to 11 who were born with critical heart defects and had heart surgery in their first three months. Researchers want to find out how many of these children develop learning, attention, or behavioral problems, and why. They will use blood tests and brain assessments to look for genetic and other factors that might link heart and brain development. The goal is to catch these issues early and improve support for affected children and families.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to earlier detection and better support for children with heart defects who are at risk for learning or behavioral challenges.
What could go wrong
This is an observational study, not a treatment trial. It will not directly change how children are treated, and results may take years to influence care.
