The success of ablation is determined by the absence of recurrence of atrial fibrillation in the short term beyond 3 months, medium and long term on regular clinical follow-up and ECG holters. The patient cohort followed since 2007 allows a very long-term follow-up of patients who have benefited from atrial fibrillation cryoablation.~Isolation of the pulmonary veins by cryoballoon (IVP) has emerged as an alternative to radiofrequency in the treatment of drug resistant atrial fibrillation (AF). (1) The potential benefits of cryoablation include shorter procedure times, decreased fluoroscopy time, shorter hospital duration, a different rate and type of complications compared to radio frequency offers potential benefits, including Including shorter procedure times, a decrease in the length of hospital stay 1 and a reduction in fluoroscopic time. (2) Effectiveness on a one year follow-up in cryoablation for AF is comparable to that of radiofrequency ablation in a prospective, randomized study with a lower major complication rate (3,4). The number of subjects is limited and most retrospective studies on cryoablation have a limited number of patients or an average follow-up not exceeding one year.~Study of the data and results of the procedures of ablation of AF by cryoablation and long-term follow-up of the patients of the CHU of Grenoble.~Regular monocentric cohort study based on collected data To identify the success rate of cryoablation ablation in paroxysmal and persistent AF
The aim of this study was to assess the long-term success rates of pulmonary vein isolation using first and second generation cryoballoons in patients with paroxysmal and persistent atrial fibrillation.
