Repeat TTE revealed a LVEF of 20% with a dilated left ventricle (Figure 1A and Additional files 1 and 2, movies 1 and 2). TTE showed a non-dilated left ventricle, an absence of segmental contractility alterations, and a LVEF in the normal range (Figure 1B and Additional files 3 and 4, movies 3 and 4).
Cardiac-MRI images: (A) Cardiac MRI gradient echo sequence showing normal dimensions and function of the left ventricle. (B) T2-weighted short tau inversion recovery sequence showing the absence of edema. (C) Late gadolinium hyperenhancement sequence without pathological contrast captation.

Repeat TTE revealed a LVEF of 20% with a dilated left ventricle (Figure 1A and Additional files 1 and 2, movies 1 and 2). Prior to the patient's discharge, cardiac MRI was performed, which showed a preserved LVEF (Figure 2).
