Figure 1 Left Atrial Injury Before PVAI and 3 Months After PVAI on 3D DE-CMRI
Left panels show LA wall slices at baseline (A) and 3 months after PVAI (B) on 3D navigated DE-CMRI in 4 different patients. Right panels show 3D rendering of LA in Patient #1 before and after PVAI in multiple views (posterior, right, left, and superior) reconstructed from MRI slice data. Post-PVAI hyperenhancement of LA wall is clearly seen (yellow arrows) in regions subjected to RF ablation and suggests scarring. 3D = three-dimensional; DE-CMRI = delayed-enhancement cardiac magnetic resonance imaging; LA = left atrial/atrium; MRI = magnetic resonance imaging; PVAI = pulmonary vein antrum isolation; RF = radiofrequency.
