Zusammenfassung:- Myocarditis in adolescents has been diagnosed clinically following the administration of the second dose of an mRNA vaccine for coronavirus disease 2019 (COVID-19). - To examine the autopsy microscopic cardiac findings in adolescent deaths that occurred shortly following administration of the second Pfizer-BioNTech COVID-19 dose to determine if the "myocarditis" described in these instances has the typical histopathology of myocarditis. - Clinical and autopsy investigation of two teenage boys who died shortly following administration of the second Pfizer-BioNTech COVID-19 dose. - The microscopic examination revealed features resembling a catecholamine-induced injury, not typical myocarditis pathology. - The myocardial injury seen in these post-vaccine hearts is different from typical myocarditis and has an appearance most closely resembling a catecholamine-mediated stress (toxic) cardiomyopathy. Understanding that these instances are different from typical myocarditis and that cytokine storm has a known feedback loop with catecholamines may help guide screening and therapy.
