This reduced activity can lead to physical deconditioning, impaired quality of life, and increased cardiovascular risk later in life. While exercise-based rehabilitation is highly recommended, significant knowledge gaps persist regarding the long-term impact of structured exercise on diverse CHD subtypes, optimal modalities, and standardized protocols for implementation. This meta-analysis assesses the effect of structured exercise rehabilitation programs on functional and health-related outcomes in children with CHD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A comprehensive search was done using PubMed\/MEDLINE, Embase, and Web of Science until April 23, 2025, for randomized controlled trials (RCTs) and observational studies which compares exercise or cardiac rehabilitation with standard of care or no rehabilitation intervention in pediatric CHD patients. Key outcomes included changes in exercise duration, peak oxygen uptake (peak VO2), peak workload, heart rate, and other cardiopulmonary parameters.
