New trial aims to halve deaths in newborns with severe heart disease
NCT ID NCT07363538
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares performing heart surgery on newborns with complex congenital heart disease either before or after 7 days of age. Researchers will track which timing leads to fewer deaths and better recovery. The trial involves 738 babies across multiple hospitals in China.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical operation
- What this could lead to
- If successful, this could establish the best timing for life-saving heart surgery in newborns, potentially halving death and non-recovery rates.
- What could go wrong
- This is a large trial but still early in its evaluation. The optimal timing may vary by individual, and results may not apply to all hospitals or countries.
