Summary

This study is looking at a new blood marker called sST2 to see if it can better detect heart failure in children after congenital heart surgery. Researchers will measure sST2 levels in 225 children under 18 during and after surgery, and at a follow-up 9-12 months later. They will compare sST2 to standard markers to see if it is more reliable and less affected by factors like age or kidney injury.

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 a more reliable blood test to detect heart failure early in children after heart surgery.
What could go wrong: This is an observational study, not a treatment trial. The marker may not prove more useful than existing tests, and results may not apply to all children.
