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 This study
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
The trial has finished. Results may not be published yet.
Stopped early

Summary

This study will test a new, non-invasive ultrasound technique that captures brain blood flow in real time for infants with congenital heart disease. Researchers aim to understand how medical treatments and surgeries affect the brain, potentially explaining why some children later have learning or movement problems. The study will include 300 infants under 2 years old at a French hospital.

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 better monitoring tools to prevent brain injury in infants with heart defects.
What could go wrong
This is an early observational study, not a treatment trial. It may not directly improve outcomes, and the technology may not prove clinically useful.

This is an AI summary of the original study and may miss details. Read our disclaimer.
