Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this retrospective study is to compare the long-term follow-up outcomes of pulses field ablation (PFA) Vs. radiofrequency ablation (RFA) for the patients with paroxysmal supraventricular tachycardia (PSVT). The main question to answer is:

Does the PFA was more effecient and safer that RFA for treatment of PSVT during procedure and after 1-year follow-up? Researchers will compare the acute and long-term efficiency and safety between PFA and RFA.

1. Recieved PFA or RFA 1 year ago
2. Finish the visit to the clinic at 1, 3, 6, 12 months for examinations and blood testings
3. Patients recieved PFA and PFA under propensity matched comparison according to differen variety of PSVT

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PFA group

A retrospective analysis was conducted on 214 patients with PSVT recieving PFA who met the inclusion and exclusion criteria and visited at the First Affiliated Hospital of Ningbo University, the Third People's Hospital of Chengdu, the Xiamen Cardiovascular Hospital of Xiamen University, the First Hospital of Jilin University, the Seventh People's Hospital of Zhengzhou, Shanghai General Hospital, and Jiangxi Provincial People's Hospital from October 2022 to June 2024. These patients were included in the PFA group. Basic clinical information, procedural data, and the efficiency and safety post 1-year follow-up were collected and analyzed.

Focal Pulsed Field Ablation (PFA)

Intervention Type PROCEDURE

Patients in the PFA group underwent ablation procedures utilizing a force-sensing PFA catheter for the treatment of PSVT.

RFA group

A retrospective analysis for control group was conducted on patients with PSVT reciecing RFA who met the inclusion and exclusion criteria and visited at the First Affiliated Hospital of Ningbo University the Third People's Hospital of Chengdu, the Xiamen Cardiovascular Hospital of Xiamen University, the First Hospital of Jilin University, the Seventh People's Hospital of Zhengzhou, Shanghai General Hospital, and Jiangxi Provincial People's Hospital from October 2022 to June 2024. 214 patients approached by RFA were matched 1:1 by propensity score to a similar population treated by PFA. Basic clinical information, procedural data, as well as the efficiency and safety of 1-year follow-up were collected and analyzed.

Focal Radiofrequecy Ablation (RFA)
