Vortexes of fiber bundles (white circles) are observed within the ventricular walls and trabeculations of the systemic RV, especially at the base of papillary muscles and large muscle bundles. Some are evident in planar tensor field images (a – MA/AA, b – DIRV, c – C-TGA). Others are more complex and are visible only in 3D tractograms (Supp video 9). We speculate that these could be a substrate for reentry arrhythmias
