Abstract
The circumferential electrical isolation of the pulmonary vein (PV) antra represents the cornerstone of all atrial fibrillation (AF) treatments. Traditionally, PV isolation by means of radiofrequency (RF) ablation is achieved using a point-by-point technique, which makes it difficult to create circular and contiguous lesions, potentially allowing conduction gaps and incomplete (nontransmural) lesions in cases of poor catheter-tissue contact. Cryoballoon ablation is now emerging as an important alternative to RF ablation.
