Fig. 4: CMRI showing both ischemic and non-ischemic LGE patterns.

CMRI revealed partly similar delayed enhancement patterns in the short- (A–D) and long-axis projections (E–H) of individuals V:24 (A, E), V:29 (B, F), V:31 (C, G), and IV:11 (D, H). A detailed description of all LGE findings (indicated by white and black arrows) can be found in Supplementary Table 3. The left ventricle is denoted by LV and the right ventricle by RV.
