Summary

This study at Boston Children's Hospital will test whether measuring thousands of proteins in a few drops of blood can predict which children with congenital heart disease will have serious complications after heart surgery. Researchers will collect blood samples from 60 children before and after surgery and combine protein profiles with clinical data to build a risk-prediction model. The goal is to move from a one-size-fits-all approach to personalized care in the Cardiac ICU.

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 blood test that helps doctors predict which children are at highest risk for complications after heart surgery, allowing earlier and more personalized treatment.
What could go wrong: This is a small, early feasibility study (60 participants) that is only looking for patterns in proteins, not testing any treatment. The findings may not lead to a usable prediction tool or improve outcomes.
