Abstract:
Objective To compare the different therapeutic efficacies between radiofrequency and cryoballoon ablation in atrial fibrillation(AF)patients with enlarged left atrium.Methods A total of 106 AF patients with enlarged left atrium(LAVI)>34ml/m2 who visited our center between December 2016 and May 2022 for catheter ablation were enrolled.They were divided into radiofrequency group(R-group)and cryoballoon group(C-group)according to the procedure.The recurrence of AF was compared between the two groups.Results The median follow-up time was 12 months and no death occurred.The rate of loss of follow-up was 3.8%.The overall recurrence rate of AF after ablation was 36.8%.There was no significant difference in clinical baseline between the two groups(P>0.05).The radiofrequency group had longer operation time(P<0.001),shorter X-ray time and less exposure(P<0.05);There was no significant difference in clinical baseline and postoperative complications between the two groups(P>0.05).The results of survival analysis showed that there was no significant difference in the survival rate of patients without atrial fibrillation/atrial flutter/atrial tachycardia between the two groups(P>0.05).Conclusion For AF patients with enlarged left atrium,the clinical effects of the two methods were similar.Cryoballoon takes a shorter time,while radiofrequency has a lower X-ray time and exposure dose for physicians and patients.Therefore,appropriate ablation methods should be selected according to the actual situation.
