Acute Myocarditis in a Patient Following mRNA-1273 SARS-CoV-2 Vaccination

Abstract

We herein report a case of acute myocarditis possibly related to the second dose of an mRNA-COVID-19 vaccine in a 45-year-old woman with no remarkable medical history. She had a fever for one week following the second dose of the mRNA-1273 SARS-CoV-2 vaccine. One week later, she presented with chest pain and electrocardiogram changes. Her serum troponin levels were elevated upon admission. Echocardiography showed segmental wall motion abnormalities of the apex, apical portion of the anterior and inferior walls. The findings of cardiac magnetic resonance imaging were consistent with acute myocarditis.
