Observational StudyClinical outcome of 2nd generation cryoballoon pulmonary vein isolation in patients over 75 years of age.
Pulmonary vein isolation is an established therapy for symptomatic atrial fibrillation. Despite the fact that incidence and prevalence of atrial fibrillation increases with age, patients over 75 years of age have been excluded in all major atrial fibrillation ablation trials. Pulmonary vein isolation with the cryoballoon has been shown to be equally effective compared to irrigated radiofrequency catheter ablation, but patients over 75 years have also been excluded. The 2nd generation cryoballoon has shown superior efficacy compared to the 1st generation cryoballoon. The aim of the study was to assess the efficacy of pulmonary vein isolation with the 2nd generation cryoballoon for symptomatic atrial fibrillation in elderly patients over 75 years. ⋯ Pulmonary vein isolation with the 2nd generation cryoballoon appears to be an effective treatment for symptomatic atrial fibrillation also in patients over 75 years of age.
