• 

  Fig. 1. Case 1: Figure 1. 4D Flow 3D rendering. A labeled still-frame outlining the right atria (RA) and left (LA) atria, and right (RV) and left (LV) ventricles. The location of the unroofed coronary sinus is shown as a dotted line with an arrow demonstrating the direction of the shunt flow near the os of the coronary sinus

• 

  Fig. 2. Case 2: Figure 1. Still frame angiogram in a coronal plane. Right sided transverse aortic arch (TAO) with a left descending aorta (DAo) and aberrant left subclavian artery (LSCA)

• 

  Fig. 3. Case 2: Figure 2. Still frame angiogram in an axial plane. Right sided transverse aortic arch (TAO) with a left descending aorta (DAo) and aberrant left subclavian artery (LSCA). AAO ascending aorta

• 

  Fig. 4. Case 2: Figure 3. Still frame 3D reconstruction of aortic arch. Right sided aortic arch with a left descending aorta (DAo) and aberrant left subclavian artery (LSCA). AAO ascending aorta, LCCA left common carotid artery, RCCA right common carotid artery, RSCA right subclavian artery

• 

  Fig. 5. Case 3: Figure 1. 12-lead electrocardiogram (ECG). Sinus rhythm, right atrial abnormality, and diffuse nonspecific ST changes

• 

  Fig. 6. Case 3: Figure 2. Event monitor. Ventricular tachycardia at 240 beats per minute

• 

  Fig. 7. Case 3: Figure 3. CMR scar imaging. Comparison of standard “bright blood” segmented inversion recovery images (A) with “dark blood” technique (FIDDLE, B). RA and RV endocardial late gadolinium enhancement (LGE) is readily apparent on dark blood imaging

• 

  Fig. 8. Case 5: Figure 1. Short axis mid (A), apical (B), four chamber (C), two chamber (D) LGE images acquired with GRE readout and PSIR reconstruction. Prior CMR from 2019 with subendocardial enhancement in the LV and RV apices, extending to the mid-ventricular level, and of the basal anterolateral subendocardium

• 

  Fig. 9. Case 5: Figure 2. Short axis mid (A), apical (B), four chamber (C), two chamber (D) LGE images acquired with gradient echo (GRE) readout and phase sensitive inversion recovery (PSIR) reconstruction. Follow up CMR from 2020 with subendocardial enhancement in the LV and RV apices. Note the improved contrast to noise between the fibrotic layer and the LV cavity blood pool when blood pool nulling is used

• 

  Fig. 10. Case 5: Figure 3. Magnitude mid (A) and apical (B) short axis images corresponding to PSIR from Figure 2 Case 5. This demonstrates the blood pool nulling technique

• 

  Fig. 11. Case 5: Figure 4. Multi-echo GRE fat water separation sequence: out of phase (A) and fat only (B). Subendocardial fat deposition is depicted by the arrowheads

• 

  Fig. 12. Case 5: Figure 5. Cine balanced steady state free precession (bSSFP) four chamber. Hypointense regions within the subendocardium (arrows) corresponding to scattered areas of fat deposition
