NCT ID NCT07572435
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 12-week home-based cardiac rehabilitation program can improve heart function and quality of life in children aged 8 to 18 with complex congenital heart disease. Participants will be randomly assigned to either the remote rehab program or standard care. The goal is to see if this convenient approach helps kids exercise better and feel healthier.
