Baseline cardiovascular magnetic resonance. There was patchy mid‐wall LGE and mildly increased ECV of 36% in the basal septum; no increased global myocardial native T₁, T₂ values (1334 and 51 ms, respectively) or signal intensities on T2‐weighted images were observed. These findings were inconsistent with the 2018 Lake Louise criteria for a diagnosis of acute myocarditis. (Normal values at our institution: native T₁:1314 ± 29 ms, T₂:46 ± 5 ms, ECV: 26 ± 5%). ECV, extracellular volume fraction; LGE, late gadolinium enhancement.
