Since 2019, the SARS-CoV-2 has been associated with the occurrence of myocarditis. Moreover, specifically in the pediatric population, this virus can cause an exaggerated inflammatory response several weeks after the acute infection. This new entity is called “multisystem inflammatory syndrome in children” (MIS-C). Cardiovascular involvement is very common in this syndrome, particularly in the form of ventricular dysfunction with increased cardiac enzymes. As myocardial damage is one of the causes of sudden cardiac death in young athletes, resumption of sporting activities must be undertaken with caution. Depending on initial symptoms, a focused history taking and meticulous physical examination may be sufficient to permit resumption of sports after the legal duration of quarantine in case of simple COVID-19 infection. In other cases, the patient should be referred to a pediatric cardiologist for a more comprehensive workup. For patients with MIS-C, sport remains contraindicated for a period of 3 to 6 months. Sport should in any case be resumed gradually, with the patient, his parents, and trainers being made aware of the possible appearance of cardiorespiratory symptoms.
What is already known about the topic?
Myocardial damage of viral origin is a risk factor for sudden cardiac death in young athletes. By analogy, there are arguments in the literature to restrict sports activities after SARS-CoV-2 infection.
What does this article bring up for us?
This manuscript provides clear recommendations for the resumption of sports activities in children after SARS-CoV-2 infection.
