The analysis of clinical efficacy and safety by cryoballoon catheter ablation surgery
Abstract：Objective To evaluate the cryoballoon catheter ablation surgery clinical efficacy and safety.Methods Selected 38 patients with paroxysmal atrial fibrillation by the cryoballoon catheter ablation surgery for atrial fibrillation ablation between June 2014 to June 2015 in Tongji hospital affiliated to Huazhong university of science and technology.Results Of atrial fibrillation ablation procedures the average time (125.5 ± 38.2)min,average fluoroscopy time (27.4± 13.0)min,average cryoablation time (36.9± 12.8)min,catheter ablation immediate success rate of 92.7％,the average pulmonary veins freezing times 2-6 (4.0±1.2)beats/root.Each pulmonary vein immediate success:left superior pulmonary vein was 95.3％,lower left pulmonary vein 92.5％,right superior pulmonary vein 93.2％,right inferior pulmonary vein 89.7％.When intraoperative right superior pulmonary vein ablation,merge one phrenic nerve palsy patient,the incidence was 2.6％;one patient relapsed from return visit within 12 months after surgery,the recurrence rate was 3％ in.Conclusion The cryoballoon catheter ablation surgery is safe,and has a good clinical efficacy.
