Lake Louise Criteria (LLC) and Functional Impairment in patients with COVID-19 and patients with Myocarditis. (A) Comparison of the CMR LLC and endomyocardial biopsy (EMB) findings. Three out of 32 (9%) patients with COVID-19 and all 22 (100%) of the patients with myocarditis have positive LLC, (B) from the patients in which endomyocardial biopsy (EMB) was available: none of the patients with COVID-19 and 13 (87%) out of 15 patients with myocarditis with available EMB had histological findings in keeping with this diagnosis, 1 (10%) of the patients with COVID-19, and 2 (13%) of the patients with myocarditis have positive LLC but negative EMC diagnostic criteria. (C) tables with numeric values for CMR LLC (upper rows) and Endomyocardial Biopsy Analyses (lower rows) (D) spidernet representation of myocardial inflammation, injury, pericardial involvement, LV, and RV dysfunctions in all COVID-19 (blue polygons) and all Myocarditis (red polygons) patients, (E) (baseline), (F) (follow-up)spidernet representations of myocardial inflammation, injury, pericardial involvement, LV, and RV dysfunctions in patients with COVID-19 (blue polygons) and Myocarditis (red polygons) with an available follow-up scan.
