方法

采用回顾性队列研究设计，收集2019年2月至2021年7月在我科行经导管房颤射频消融术的患者，根据其是否使用ICE，将其分为ICE组(

Abstract

Objective

To investigate the efficacy and safety of catheter ablation for atrial fibrillation under the guidance of intracardiac echocardiography (ICE).

Methods

A retrospective cohort trial was conducted on all the patients who underwent radiofrequency catheter ablation due to atrial fibrillation in our department from February 2019 to July 2020. They were divided into ICE group (

=192) and non-ICE group (

=167). The radiation exposure time

radiation exposure amount

total ablation time

single coil isolation rate

and incidence of complications were compared between the 2 groups to evaluate the efficacy and safety of ICE-guided ablation for atrial fibrillation.

Results

The ICE group had significantly shorter total ablation time (68.35±1.09

74.37±1.69 min

0.01)

higher single coil isolation rate (70.83%

53.89%

0.01)

less radiation exposure amount (33.86±1.51

212.30±21.11 mGy

0.01) and shorter radiation time (4.90±0.23

13.51±0.34 min

0.01) when compared with the non-ICE group. No statistical difference was seen in the incidence of complications between the 2 groups. Complications were observed in 2 cases of both groups. There were no serious complication in the ICE group

while 1 case of intraoperative cardiac perforation was in non-ICE group. Though no significant difference was found in the early and late recurrence rates of ablation in the ICE group than the non-ICE group

a decreasing trend in late recurrence rates was observed in both groups (3.13%

7.78%

=0.06).

Conclusion

ICE-guided catheter ablation of atrial fibrillation has higher ablation efficiency and less radiation exposure. There is no significant difference in safety between the 2 groups

but ICE leads to a decreasing trend in late recurrence rate.
