Excerpt
In this issue of the journal, Doeblin et al. [
1] report on a comparative cardiac magnetic resonance (CMR) study in patients after COVID-19 infection versus vaccination, presenting with suspected cardiac involvement due to limiting clinical cardiac symptoms in a tertiary cardiac center. The authors investigated several CMR metrics, including left ventricular (LV)-ejection fraction, myocardial fibrosis, and edema by T1 and T2 mapping techniques, respectively, extracellular volumes (ECV) and late gadolinium enhancement (LGE) extent and patterns in 104 patients after COVID-19 infection and 27 individuals after vaccination. In addition, the updated ‘Lake Louise Criteria’ incorporating non-ischemic patterns of myocardial damage and edema by T2 mapping and LGE for the diagnosis of myocarditis [
2] were systematically applied in both patient groups. Of note, the presence of other cardiac pathologies, such as myocardial ischemia, pericardial effusion and pericardial LGE, compatible with pericarditis were also evaluated. …
