Abstract

Abstract:

Objective

This study investigated the efficacy and safety of intracardiac echocardiography (ICE) on radiofrequency ablation of arrhythmias.

Methods

From May 2020 to February 2021, a total of 200 patients (60.40±12.14 years old, male 126) with arrhythmia were treated with radiofrequency ablation in our center. They were divided into ICE group and control group according to whether ICE was used during operation. The intraoperative fluoroscopy time, complications and operation success rate were compared between the two groups. Results

Conclusion

ICE can significantly improve the safety of radiofrequency ablation of arrhythmias.

Key words: Arrhythmia, Radiofrequency ablation, Intracardiac echocardiography, 3D Mapping system, Atrial fibrillation
