Persistent Cardiac MRI Findings in a Cohort of Adolescents with post COVID-19 mRNA vaccine myopericarditis

Myopericarditis, , has emerged as an important adverse event following COVID-19 mRNA vaccination, particularly in adolescents [1]. Patients typically exhibit chest pain and an elevated serum troponin level in the days following the COVID-19 mRNA vaccine. They usually are hemodynamically stable, and symptoms and cardiac biomarkers normalize within a few days [2]. cardiac magnetic resonance studies, when performed early, frequently demonstrate abnormalities such as edema and late gadolinium enhancement (LGE), meeting Lake Louise Criteria for diagnosing myocarditis noninvasively [2,3].
