Evaluation of the efficacy and safety of catheter ablation guided by three-dimensional intracardiac ultrasound in the treatment of atrial tachyarrhythmia
Objective:To explore the clinical efficacy and safety of three-dimensional intracardiac ultrasound(ICE)guided catheter ablation in the treatment of atrial tachyarrhythmia.Method:A total of 88 patients with atrial tachyarrhythmia were retrospectively selected,and all patients underwent radiofrequency catheter ablation(RFCA)treatment.Among them,38 patients received intraoperative use of ICE(observation group)and 50 patients did not receive intraoperative use of ICE(control group).The modeling time,atrial septal puncture time,ablation success rate,and incidence of adverse reactions were compared between the two groups.Results:Compared with the control group,the observation group had significantly shorter modeling time,atrial septal puncture time,left pulmonary vein ablation time,right pulmonary vein ablation time,and X-ray exposure time(P＜0.05).There was no statistically significant difference in Al values between the two groups of ablated pulmonary vein segments(posterior wall,bottom,anterior wall,top,and crest)(P＞0.05).The success rate of first ablation in t he observation group was 97.4％(37/38),while in the control group it was 82.0％(41/50).The success rate of ablation in the observation group was significantly higher than that in the control group)(P＜0.05).The recurrence rate during follow-up in the observation group was significantly lower than that in the control group(2.6％vs.12.0％,P＜0.05).The total incidence of intraoperative complications in the observation group was significantly lower than that in the control group,with a statistically significant difference(5.3％vs.14.0％,P＜0.05).Conclusions:RFCA treatment for atrial tachyarrhythmia guided by three-dimensional ICE can effectively improve the success rate of ablation,shorten surgical time,reduce X-ray exposure,and reduce the risk of intraoperative complications.
