Cardiac MRI from Case 1: T2 maps (top row) demonstrate patchy focal areas of myocardial edema in the anterior wall and inferior wall (black arrows). Late gadolinium enhancement (LGE) images (bottom row) demonstrate patchy focal areas of scar (yellow arrows). These findings are consistent with myocarditis

Cardiac magnetic resonance imaging (CMR) revealed evidence of myocardial edema and late gadolinium enhancement in the subepicardial mid-inferior wall consistent with acute myocarditis (Fig. 1).
Electrocardiogram for Case 1. Taken on the final hospital day in the setting of clinical decline and three hours prior to final cardiac arrest. Junctional tachycardia, abnormal R-wave progression, prolonged QTc (532 msec)
