Abstract:
Objective To comprehensively evaluate the clinical effect of cryoballoon ablation (CBA) and radiofrequency ablation (RFA) in treating paroxysmal atrial fibrillation (PAF).Methods Computer retrieval of PubMed,EMbase,the Cochrane Library,Web of Knowledge,China national knowledge infrastructure (CNKI),Chinese Biomedical Medical Literature (CBM),China Wan Fang,China VIP,and other database to collect the randomized control trials (RCT) related to RFA and CBA treatment for PAF.The retrieval time was from the establishment of database to December 2015.The data extraction and methodological quality of the included studies were assessed by two reviewers independently.And meta-analysis was conducted by using RevMan 5.2 software.Results A total of 6 research papers (636 patients in total) were included.The results of meta-analysis showed that the incidence of phrenic nerve paralysis in CBA group was significantly higher than that in RFA group (RR=9.26,95％CI:2.17-39.63,P=0.003).No statistically significant differences in the operation time (MD=10.07,95％CI:-9.10-30.52,P=0.29),fluoroscopy time (MD=-0.18,95％CI:-8.14-7.77,P=0.96),12-month success rate (RR=0.91,95％CI:0.72-1.14,P=0.40) and the incidences of atrial tachycardia,atrial flutter,atrioventricular reentrant tachycardia existed between CBA group and RFA group (RR=0.47,95％CI:0.11-2.02,P=0.31).Conclusion For the treatment of PAF,no obvious differences in the operation time,fluoroscopy time,12-month success rate,and the incidences of atrial tachycardia,atrial flutter,atrioventricular reentrant tachycardia exist between CBA and conventional RFA,but CBA can increase the incidence of phrenic nerve paralysis.
