چکیده انگلیسی

BackgroundThe efficacy of the second-generation cryoballoon (CB) in patients with paroxysmal atrial fibrillation (AF) has been demonstrated previously. Data on the efficacy of CB ablation in patients with persistent AF are sparse.ObjectiveThe aim of this study was to evaluate the 2-year success rate of pulmonary vein isolation in patients with persistent AF using the second-generation CB.MethodsFifty consecutive patients (mean age 64.6 ± 9.9 years; 19 women [38%]) with persistent AF were included in this analysis. The mean follow-up period was 22 ± 11 months. All patients were ablated using the second-generation 28-mm CB. Isolation of the pulmonary veins was confirmed using a spiral mapping catheter. In all patients, follow-up was obtained using 24-hour Holter monitoring or via interrogation of an implanted loop recorder or pacemaker.ResultsThe mean left atrial diameter was 43.6 ± 5.6 mm, the mean CHA2DS2-VASc score was 2.8 ± 1.5, and the mean HAS-BLED score was 2.1 ± 1.2. The mean fluoroscopy time was 25.8 ± 9 minutes, and the mean procedural time was 146.4 ± 37.8 minutes. After 22 ± 11 months, the frequency of arrhythmia recurrence was 22 of 50 (44%) in the overall group (paroxysmal AF 6 of 22 [27%]; persistent AF 16 of 22 [73%]). No major complications occurred. Aneurysma spurium not requiring surgical intervention occurred in 1 (2%) patient. No phrenic nerve palsy was observed.ConclusionTwo years’ results after pulmonary vein isolation using the second-generation CB in patients with persistent AF are promising. The clinical success rate appears to be similar to the reported success rates of radiofrequency ablation for the treatment of persistent AF.
