Abstract: Computed tomography (CT) images of stenotic pulmonary vein before (A) and after atrial fibrillation catheter ablation (AFCA) (B). Kaplan–Meier curves for the cumulative incidence of pulmonary vein stenosis after AFCA. Top arrow of (A) pre-procedural right inferior pulmonary vein (RIPV), bottom arrow of (A) pre-procedural three-dimensional (3D) reconstructed image of RIPV, and arrows of (B) stenotic RIPV after AFCA. AF, atrial fibrillation; ConvP-AFCA, conventional power atrial fibrillation catheter ablation; HPSD, high-power short duration.
