Summary

This study tests whether wearing compression garments on the legs can increase the amount of blood the heart pumps during exercise in adults with Fontan circulation. Twenty participants will undergo exercise tests with and without the garments, and a subset will wear them for two weeks. The goal is to see if this simple device can improve exercise function.

What this could mean

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

Active substance: lower extremity compression garments
What this could lead to: If it works, compression garments could become a simple, non-drug way to improve exercise capacity and quality of life for people with Fontan circulation.
What could go wrong: This is a very small, early-stage study (20 people) testing a short-term effect. It may not show a meaningful benefit, and results may not apply to all Fontan patients.
