Summary
This study tested whether a live-video-supervised exercise program could improve fitness in children and teens (ages 8-19) born with a single ventricle, a condition often treated with the Fontan procedure. Participants exercised three times a week for three months, then a maintenance phase. The goal was to see if this approach could safely boost exercise capacity, muscle strength, and overall health, potentially lowering the risk of heart failure later in life.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
live-video-supervised exercise (aerobic + resistance training)
What this could lead to
If it works, this could lead to a safe, home-based exercise program that improves fitness and muscle health in children with Fontan circulation, potentially reducing long-term heart failure risk.
What could go wrong
This is a completed trial, but it was relatively small (150 participants) and focused on short-term fitness gains. It may not prove that exercise reduces death or need for transplant, and results may not apply to all Fontan patients.
