Cryoballoon ablation in high versus low volume centers – Does experience make a difference?

Pulmonary vein isolation (PVI) has become the widely accepted cornerstone of atrial fibrillation (AF) ablation to suppress initiation of atrial fibrillation by triggers located within the pulmonary veins [1,2]. Isolation of the pulmonary veins can be achieved by point-by-point radiofrequency (RF) ablation either fluoroscopically guided close to the ostium (segmental PVI) or by creating an ablation line at a greater distance around the ipsilateral pulmonary veins (circumferential ablation) guided by a 3D electroanatomical mapping system, the latter now being the gold standard [2,3].
