Diagnosis and Treatment of Myocarditis in Children in the Current Era

“Myocarditis has distinct characteristics in children and a potential impact on their lifelong health. We hope that this statement serves as an educational update as well as a unifying call for much needed research to better understand and treat this important pediatric condition. And, in light of the recently recognized occurrence of myocarditis after COVID-19 infection, as well as the emergence of cases of suspected myocarditis after COVID-19 vaccination, this statement is a resource for clinicians and health care professionals in caring for these patients.”

“This statement highlights advances in our understanding of the immunopathogenesis, new and shifting dominant pathogeneses, modern laboratory testing, and use of mechanical circulatory support, with a special emphasis on innovations in cardiac magnetic resonance imaging. Despite these strides forward, we struggle without a universally accepted definition of myocarditis, which impedes progress in disease-target therapy.”
