A report on short-term follow-up cardiac imaging and clinical outcomes of myocarditis after coronavirus disease 2019 vaccination

Abstract

To the Editor, Myocarditis as a rare complication after coronavirus disease 2019 (COVID-19) mRNA vaccination in adolescents and young adults has been recently reported; 1,2 however, follow-up data was lacking. MethodsThis is an observational case series of patients who were diagnosed with myocarditis after mRNA COVID-19 vaccination. The clinical characteristics, short-term (4-6 months) follow-up cardiac imaging and clinical outcomes are described.

Cardiovascular imaging updates and future perspectives

“…In patients with myocarditis correlated with COVID-19 vaccination, the reduction in late-gadolinium-enhancement burden correlated with the resolution of myocardial edema and inflammation. 40 Taken together, these data highlight the central role of a comprehensive cardiovascular imaging assessment in patients affected by cardiovascular disease in terms of preventions, early diagnosis and response to treatment (Fig. 1).…”

“…Transthoracic echocardiography usually shows a preserved ejection fraction; MRI is essential for the diagnosis, according to the modified Lake Louise Criteria. In patients with myocarditis correlated with COVID-19 vaccination, the reduction in late-gadolinium-enhancement burden correlated with the resolution of myocardial edema and inflammation 40 …”
