Introduction Radiofrequency ablation (RFA) aiming at the electrical isolation of the pulmonary vein (PV) is more effective in controlling the rhythm than drugs, especially in young individuals with symptomatic paroxysmal atrial fibrillation (AF) without structural heart disease.– Electrical isolation is performed with point-by-point RFA around the PV, constituting a complex and lengthy procedure., Recently, technologies have been developed aiming to simplify PV isolation, among them the balloon cryoablation., In this approach, the cryoballoon is inflated in the PV ostium in […]
