Cardiac Magnetic Resonance Findings of COVID-19 Vaccine-Associated Myopericarditis at Intermediate Follow Up: A Comparison with Classic Myocarditis.

ABSTRACT:

Objective

To report intermediate cardiac magnetic resonance (CMR) findings of COVID-19 vaccine associated myopericarditis (C-VAM) and compare with classic myocarditis.

Study design

Retrospective cohort study including children diagnosed with C-VAM from 5/2021 through 12/2021 with early and intermediate CMR. Patients with classic myocarditis from 1/2015 through 12/2021 and intermediate CMR were included for comparison.

Results

There were 8 patients with C-VAM and 20 with classic myocarditis. Among those with C-VAM, CMR performed at median 3 days (IQR 3, 7) revealed 2/8 patients with left ventricular ejection fraction (LVEF)<55%, 7/7 patients receiving contrast with late gadolinium enhancement (LGE), and 5/8 patients with elevated native T1 values. Borderline T2 values
