This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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

Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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.

Summary

This study compares two surgical timings for babies born with Tetralogy of Fallot, a serious heart defect. One group gets corrective surgery within 28 days of birth, the other at the usual 3-6 months. Researchers will track deaths, reoperations, and recovery to see if earlier surgery leads to better outcomes.

What this could mean

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

Active substance
corrective heart surgery
What this could lead to
If early surgery works better, it could improve survival and long-term heart function for babies born with this serious heart defect.
What could go wrong
This is a relatively small trial (160 babies) and results may not apply to all hospitals. Surgery in newborns carries higher risks of complications.
