Conclusion
Pediatric cardiomyopathies are a heterogeneous group of diseases but affect a small portion of the population. As such, data guiding the implementation and impact of cardiac rehabilitation on this population is strikingly limited. Despite this, few guidelines do exist, and they are based on expert opinion. There are likely multiple benefits of cardiac rehabilitation in this population, ranging from microscopic to psychological, although ongoing research is necessary to fully define these benefits. However, the benefits have to be weighed against the potential risks for each patient. Finally, the limited research provides an opportunity for multicenter collaboration, as well as the implementation of evolving technology to try to overcome the limitations identified.
