Revisiting symptomatic pulmonary vein stenosis after high-power short-duration radiofrequency ablation in patients with atrial fibrillation

Abstract

Graphical 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.
