Feasibility Study of Home Cardiac Rehabilitation Program for Postoperative Children With Congenital Heart Disease

This single-arm feasibility study will pilot a home-based cardiac rehabilitation program for preschool children (aged 3 to 7 years) who have undergone corrective surgery for congenital heart disease. Following the development of the program through expert consensus, this phase will implement the preliminary version of the program in a selected sample of caregiver-child pairs over a 12-week period. The study will assess feasibility by evaluating caregiver adherence to the intervention, acceptability of the program components, and completeness of rehabilitation task records. Descriptive data on safety, participation rate, and delivery logistics will also be collected. Findings will inform refinement of the program prior to future effectiveness testing.
