Persistent Cardiac Magnetic Resonance Imaging Findings in a Cohort of Adolescents with Post-Coronavirus Disease 2019 mRNA Vaccine Myopericarditis

Jenna Schauer et al. J Pediatr. 2022 Jun.

Abstract

We describe the evolution of cardiac magnetic resonance imaging findings in 16 patients, aged 12-17 years, with myopericarditis after the second dose of the Pfizer mRNA coronavirus disease 2019 vaccine. Although all patients showed rapid clinical improvement, many had persistent cardiac magnetic resonance imaging findings at 3- to 8-month follow-up.

Cardiac MRI scans from 3 days after admission of a 16-year-old male patient who presented to the emergency department with chest pain and elevated troponin 3 days after receiving the Pfizer COVID-19 mRNA vaccine. Initial cardiac MRI. A and B, Subepicardial to midmyocardial LGE in inferior and inferolateral LV wall from base to apex (arrows). C, T2 hyperintensity in similar segments, consistent with edema. D-F, Follow-up cardiac MRI 4.4 months later. LGE is still persistent but decreased from 26% to 19.84% (arrows), and LVEF remained stable at 58%. There is improved T2 hyperintensity.
