ABSTRACT
Objective:
To investigate the efficacy and safety of catheter radiofrequency ablation for focal atrial tachycardia,by comparing conventional mapping group and Carto system mapping group.Methods:
50 patients with focal atrial tachycardia underwent electrophysiologic study and radiofrequency ablation.32 cases were in conventional mapping group,and 25 cases in Carto system mapping group,including 7 cases with unsuccessful ablation in conventional mapping group.During follow-up 20?11 months,radiofrequency ablation acute successful rate,long-term successful rate,safety,and the clinical symptoms were recorded.ⅹ-ray radiation exposure time was compared between conventional mapping group and Carto system mapping group.Results:
① radiofrequency ablation acute successful rate of conventional mapping group and Carto system mapping group were 78% and 100%,and long-term successful rate were 68% and 96% respectively.No complications occurred.The clinical symptoms caused by focal atrial tachycardia disappeared after successful ablation.② ⅹ-ray radiation exposure time of Carto system mapping group was shorter than that of conventional mapping group.Conclusions:
Successful rate and safety of radiofrequency ablation of focal atrial tachycardia were higher,and effects of Carto system mapping group were better than those of conventional mapping group.And X-ray radiation exposure time of Carto system mapping group decreased.
