Persistent Cardiac Magnetic Resonance Imaging Findings in a Cohort of Adolescents with Post-Coronavirus Disease 2019 mRNA Vaccine Myopericarditis

Cardiac Magnetic Resonance Findings of COVID-19 Vaccine Associated Myocarditis at Intermediate Follow Up: a Comparison to Classic Myocarditis and MIS-C Related Myocarditis

“…This interval was adequate time to allow for normalization of MRIs in at least half of our cohort, with 3 of the remaining patients showing persistant LGE with otherwise normal ventricular systolic function and no other evidence of active myocardial inflammation. Schauer et al and Fronza et al have also shown resolution of myocardial edema and normalization of ventricular systolic function in the same follow-up period (18,19). These studies also revealed persistent LGE albeit at a higher frequency than our group: 69% and 62%, respectively.…”

COVID-19 mRNA vaccination and myocarditis or pericarditis

“…9 However, one case-series, published in 2022, of adolescent patients found a persistence of radiographic abnormalities at follow-up examinations, which could be cause for concern. 11 However, the patients followed up had excellent clinical outcomes, suggesting minimal chronic morbidity attributable to vaccineassociated myocarditis. Nevertheless, the continuous surveillance of this patient group for any increased frequency of heart failure, sudden death, or related cardiac comorbidities is necessary.…”

Responses to comments on my paper: “COVID Update: What is the truth?”

“…A recent study demonstrated that even though the child appears to recover from the myocarditis, special scans demonstrated permanent damage to the heart muscle. [ 13 ] Several cardiologists have stated that these young men could be in danger of further heart issues later in life, which is supported by real science and clinical experience. Long-term studies are needed to truly evaluate the effects of these cases of vaccine-induced heart damage.…”
