What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether children born with heart defects who need surgery might also have delays in speech and thinking. Researchers will check the children's cognitive and language skills before their operation and again one and two years after. The goal is to see if speech problems can be an early warning sign of broader neurodevelopmental challenges in these young patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cardiovascular surgery with cardiopulmonary bypass
What this could lead to
If this study succeeds, it could help identify early signs of cognitive and speech delays in children with congenital heart defects, potentially leading to earlier interventions and support.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may not apply to all children with heart defects, and the follow-up period may be too short to capture long-term outcomes.
