The atrial myocardium was segmented and characterized with the analysis of LGE-MRI using ADAS-AF.
The patient presented a fibrotic substrate around the veins, on the anterior wall and on the roof. The total myocardial area of 124.9 cm² consisted of:
- 25.76% (32.2 cm²) dense scar tissue (red)
- 18.47% (23.1 cm²) mild fibrotic tissue (yellow)
- 55.77% (69.6 cm²) healthy tissue (blue)
The anterior wall presented two ablation gaps:
- One gap in the roof line
- One gap near the mitral valve
