The low incidence of clinically significant heart disease in school-age children following COVID-19.

The burden of clinically-apparent cardiac injury secondary to coronavirus disease 2019 (COVID-19) in school-age children is unclear. Over 12 months at a large academic pediatric hospital in the Midwestern portion of the United States, there were 1481 COVID-19 positive non-hospitalized otherwise healthy schoolaged children with 195 having cardiac testing performed. While incidental findings occurred, no definitive COVID-19 related cardiac pathology was discovered. Additionally, only ~3% of children had acute cardiac symptoms necessitating evaluation by pediatric cardiology. School-age children who were not hospitalized for COVID-19 have a very low risk of having clinically significant cardiac damage and are more likely to discover incidental findings.
