This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
Survival of children with single ventricles ("half a heart") beyond the neonatal period has increased dramatically with the staged Fontan palliation. Yet, long-term morbidity remains high. By the age of 40, 50% of Fontan patients will have died or undergone heart transplantation. With \>1,000 Fontan palliations performed in the US annually, there is a burgeoning population of Fontan patients at risk for progressive heart failure and death. Factors that contribute to onset and progression of heart failure in Fontan patients remain incompletely understood. However, it is established that Fontan patients have poor exercise capacity, associated with a greater risk of morbidity and mortality, in addition to decreased muscle mass, abnormal muscle function, and endothelial dysfunction contributing to disease progression. In adult patients with two ventricles and heart failure, reduced exercise capacity, muscle mass, and muscle strength are powerful predictors of poor outcomes, and exercise interventions can not only improve exercise capacity and muscle mass, but also reverse endothelial dysfunction. Limited exercise interventions in children with congenital heart disease have demonstrated that exercise is safe and effective; however, these studies have been conducted in small, heterogeneous groups, and most had few Fontan patients. Furthermore, none of these interventions have studied the impact of exercise on muscle mass or mitochondrial function, or endothelial function. The investigators propose a milestone-driven, randomized controlled trial in pediatric Fontan patients to test the hypothesis that a live-video-supervised exercise (aerobic + resistance) intervention will improve cardiac and physical capacity; muscle mass, strength and function; and endothelial function. The investigators' ultimate goal is the translation of this model to clinical application as an "exercise prescription" to intervene early in pediatric Fontan patients and decrease long-term morbidity and mortality.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
