Abstract：discuss the influence of radiofrequency catheter ablation (RFCA) and cryoballoon ablation (CBA) on early recurrence of atrial fibrillation (ERAF) after pulmonary vein isolation (PVI). Methods The patients with atrial fibrillation (AF, n=86) were chosen from Department of Cardiovascular Medicine in People’ s Hospital of Zhengzhou City from Apr. 2016 to Jan. 2017, among them 58 (67.4%) were the male aged from 52 to 73 (average age=61.7±9.8), and there were 76 (88.4%) cases of paroxysmal atrial fibrillation (PAF). All patients were received PVI for treating AF, and then divided, according to operation methods, into 2 groups (each n=43). There were 28 (65.1%) male cases aged from 54 to 73 (average age=63.4±9.2) in RFCA group, and there were 30 (69.8%) cased aged from 52 to 71 (average age=60.1±10.2) in CBA group. The patients were followed up after PVI for 3 months, and recurrence rate was given a statistical analysis in 2 groups. Results After followed up for 90 d, there were totally 24 (27.9%) cases of recurrence, and 11 (25.6%) in RFCA group and 13 (30.2%) in CBA group. The Kaplan-Meier survival analysis showed that the recurrence rate had no statistical difference between 2 groups (Log-Rank: P=0.758). The multi-factor Cox analysis showed that left atrial diameter (LAD, P=0.017) and persistent AF (PeAF, P=0.019) were the independent risk factors of recurrence after CBA, and LAD (P=0.023) was an independent risk factor of f recurrence after RFCA. Conclusion There is no significant difference in ERAF between 2 operation methods. LAD is an independent risk factor of ERAF after RFCA, and LAD and PeAF are the independent risk factors of ERAF after CBA.
