Acute myocarditis after a second dose of the mRNA COVID-19 vaccine: a report of two cases

Joseph Mansour et al. Clin Imaging. 2021 Oct.

Abstract

We report two cases of myocarditis, in two young and previously healthy individuals, temporally related to the second dose of the mRNA-COVID-19 vaccine. Both patients developed acute chest pain, changes on electrocardiogram (ECG), and elevated serum troponin within two days of receiving their second dose. Cardiac magnetic resonance (CMR) findings were consistent with acute myocarditis.

Keywords: Acute myocarditis; COVID-19 vaccination; Cardiac magnetic resonance; Myocarditis; mRNA-COVID-19 vaccine.

Magnetic Resonance Imaging of Case 1. Post contrast magnitude inversion recovery (MAG-IR) images in short axis (A) and four-chamber long axis (B) views show subepicardial enhancement in the anterolateral wall of the mid ventricle and apex (arrowheads). Native T1 map shows corresponding abnormality (arrowheads in C) with elevated values (D) in the anterolateral wall as compared to the interventricular septum. T2 mapping also showed abnormality in this region (arrows in E) with elevated values (F) when compared to the interventricular septum.

Magnetic Resonance Imaging of Case 2. Post-contrast magnitude inversion recovery (MAG-IR) (A) and phase sensitive inversion recovery (PSIR) (B) images in short axis views show subepicardial enhancement in the inferolateral wall at the base (arrowheads). Native T1 map shows corresponding abnormality (arrowheads in C) with elevated values (D) in the inferolateral wall as compared to the interventricular septum. T2 mapping also showed abnormality in this region (arrows in E) with elevated values (F) when compared to the interventricular septum.
