Admission and follow-up cardiac magnetic resonance imaging findings in BNT162b2 Vaccine-Related myocarditis in adolescents

Diagnosis of Acute Myocarditis Following mRNA Vaccines against SARS-CoV-2: A Methodological Review

“…However, few cases of acute myocarditis potentially associated with SARS-CoV-2 immunization have been diagnosed when performing an endomyocardial biopsy, leaving some doubts regarding the real incidence of this complication [4][5][6][7]. Indeed, most published reports have based the diagnosis of myocarditis on the result obtained by the cardiac magnetic resonance (MRI) [10][11][12][13][14], which could represent a valuable alternative for the non-invasive characterization of myocardial tissue. To further elucidate the relationship between myocarditis and the administration of mRNA vaccines against SARS-CoV-2, starting with two cases observed at the Cardiology Unit of the West Vicenza General Hospital located in the Veneto Region, which was among the first Italian areas hit by the COVID-19 pandemic, we reviewed the existing literature to highlight the clinical and diagnostic elements that could contribute to a suspicion of acute myocarditis as an adverse event of SARS-CoV-2 immunization.…”

The Power of Performing Tissue Characterization in Inflammatory Conditions

“…CMR is valuable for initial diagnosis in the acute phase as well as for follow-up. 5 Acute phase diagnostic imaging criteria were determined in 2009 6 and updated in 2018. 7 In this issue of JACC: Advances , Aviv et al 8 report their experience imaging PVM compared to imaging a matched group of patients with “classical myocarditis,” CM.…”
