Cardiac magnetic resonance imaging of myocarditis and pericarditis following COVID-19 vaccination: a multicenter collection of 27 cases

Dear Editor in Chief,

We would like to share ideas on “Cardiac magnetic resonance imaging of myocarditis and pericarditis following COVID-19 vaccination: a multicenter collection of 27 cases” [1].

Di Dedda et al. concluded that “While establishing a causal relationship between peri-myocardial inflammation and vaccine administration can be challenging, our clinical experience suggests that CMR should be performed for diagnosis confirmation and to drive clinical decision-making and follow-up” [1]. We agree that CMR is useful for diagnosis of cardiac problem. In studied cases, the vaccine recipients had cardiac problem but the problem might or might not be associated with COVID-19 vaccine. The CMR can diagnose cardiac pathological change but it cannot diagnose the cause. There is usually no data on previous vaccination cardiac status of the vaccine recipient [2]. Also, the concurrent medical problem might co-occur. For example, dengue might co-occur and cause cardiac problem in a COVID-19 vaccine recipient [2, 3].
