Figure 1:

TMEM43 arrhythmogenic cardiomyopathy. Cardiac CT and MR images in a male patient between 30 and 39 years of age (exact age not provided due to potential reidentification risk) with a TMEM43 variant of unknown significance (p.Gly280Glu) with palpitations and premature ventricular beats at Holter monitoring. (A) Axial noncontrast cardiac CT image demonstrates extensive subepicardial fat along the lateral left ventricular wall (yellow arrows). (B) Four-chamber 1.5-T steady-state free precession MR image demonstrates subepicardial chemical shift artifact along the lateral left ventricular wall (red arrows). (C) Short-axis and (D) four-chamber late gadolinium enhancement images demonstrate subepicardial late gadolinium enhancement involving the midventricular anterolateral wall, inferolateral wall, and inferior wall (orange arrows).
