The effect of left atrial remodeling after cryoballoon ablation and radiofrequency ablation for paroxysmal atrial fibrillation.

Although CBA and RFA are both effective in left atrial electrical and structural reverse-remodeling in paroxysmal AF, CBA may outperform RFA for both purposes 6 months after ablation. However, during long-term follow-up, there was no significant intergroup difference.
