Fontan surgery study: does lung blood flow type matter for kids with one heart chamber?

NCT ID NCT07535203

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study follows 52 children with cyanotic congenital heart disease and a single working heart chamber (univentricular heart) who undergo a series of surgeries ending with the Fontan procedure. Researchers will compare outcomes like survival, complications, and quality of life between two groups: those with too little blood flow to the lungs (pulmonary oligemia) and those with too much (pulmonary plethora). The goal is to understand how these differences affect recovery and long-term health after Fontan surgery.

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 study could help doctors better predict which children with univentricular heart will have better or worse outcomes after Fontan surgery, leading to more personalized care.
What could go wrong
This is an observational study, not a test of a new treatment. It only looks at existing differences in lung blood flow, so it cannot prove cause and effect. The small size (52 people) and single-center design may limit how widely the results apply.
