ECG showed atrial fibrillation, non-specific intraventricular conduction delay, and minimal ST elevation in the lateral leads (Figure 1).
Cardiac MRI, hospital Day 5. LGE (Figure 3) and T1 (Figure 4) imaging demonstrates sub-epicardial late gadolinium enhancement in the basal and mid-lateral left ventricular walls with native global T1 of 1270 +- 67 ms.

Cardiac magnetic resonance (CMR) imaging obtained on hospital day five showed a mildly dilated RV with normal free wall motion, small circumferential pericardial effusion, pericardium with normal thickness but diffuse late gadolinium enhancement, and sub-epicardial late gadolinium enhancement in the basal and mid-lateral left ventricular walls with native global T1 of 1270 +- 67 ms (Figure 2 and 3; see Supplementary material online, Video S3).

Cardiac MRI, post-discharge 2 week follow-up. T2 imaging demonstrates normal relative regional signal intensity suggesting resolution of oedema/inflammation.

A repeat CMR showed LVEF of 59%, normal RV size and systolic function, resolution of the pericardial effusion, and normal T2 signal intensity (Figure 4).
