Wang X, Song B, Qiu C, et al. - The present study was performed to evaluate the influence of atrial remodeling in patients with paroxysmal atrial fibrillation (AF) after cryoballoon ablation (CBA) and radiofrequency ablation (RFA). This nonrandomized retrospective observational study was conducted to include a total of 328 consecutive individuals who had undergone CBA or RFA for refractory paroxysmal AF in May 2014 to May 2017 in our hospital. Ninety-six individuals were included in the CBA group, and 96 were in the RFA group, after propensity score matching. Via P wave dispersion (Pdis), electrical remodeling of the left atrium was evaluated; structural remodeling was evaluated by the left atrium diameter (LAD) and left atrial volume index during scheduled visits. The results considered that CBA may outperform RFA for both purposes 6 months after ablation, although CBA and RFA are both effective in left atrial electrical and structural reverse‐remodeling in paroxysmal AF. Nevertheless, no significant intergroup difference was found during long‐term follow‐up.
