Abstract:
Objective: The compare the safety and efficacy between cryoablation (CRYO) and radiofrequency catheter ablation (RFCA) for treating the patients with atrio-ventricular nodal reentrant tachycardia (AVNRT) by meta-analysis.
Methods: We systemically searched the Medline, Cochrane library and Embase database to fulifll our pre-deifned criteria until the publication of May 2014.
Results: There were 5 randomized controlled trials (RCTs) and 14 retrospective trials enrolled in our study with 2900 patients. The patients were allocated into 2 groups:CRYO group, n=1384 and RFCA group, n=1516. The overall pool-analysis demonstrated that compared with RFCA group, CRYO group had the lower risk of permanent atrio-ventricular nodal block (OR:0.27, 95%CI 0.11 to 0.62, P<0.01) and shorter X-ray exposure time (WMD:-3.36, 95%CI-5.58 to-1.15, P<0.01);while CRYO group had the lower immediate procedural success rate (OR:0.63, 95%CI 0.42 to 0.96, P<0.05), longer procedural time (WMD:10.97, 95%CI 3.35 to 18.58, P<0.01), and higher long-term arrhythmia recurrence rate (OR:2.89, 95%CI 2.05 to 4.06, P<0.01).
Conclusion: Although CRYO could decrease the risk of permanent atrio-ventricular nodal block, while its effectiveness was lower than RFCA for AVNRT treatment in relevant patients.
