Cardiac MRI Findings of Myocarditis After COVID-19 mRNA Vaccination in Adolescents.
Background: A possible association has been reported between COVID-19 mRNA vaccination and myocarditis. Objective: To describe cardiac MRI findings in patients with myocarditis after COVID-19 mRNA vaccination. Methods: This retrospective study included patients who underwent cardiac MRI between May 14, 2021 and June 14, 2021 for suspected myocarditis within 2 weeks of COVID-19 mRNA vaccination, without known prior COVID-19. ⋯ LGE persisted in 2 patients undergoing repeat MRI. The observations do not establish causality. Clinical impact: Radiologists should be aware of the possible association of COVID-19 mRNA vaccination and myocarditis, and recognize the role of cardiac MRI in assessment of suspected myocarditis after COVID-19 vaccination.
