Comparing Pulsed Field Ablation and Radiofrequency Ablation for Treating Paroxysmal Supraventricular Tachycardia A Retrospective Study with One-Year Follow-Up

What this Trial Is About

Researchers are comparing the long-term results of two procedures, Pulsed Field Ablation PFA and Radiofrequency Ablation RFA, for patients with paroxysmal supraventricular tachycardia PSVT. This retrospective study aims to find out whether PFA is more efficient and safer than RFA during the procedure and after one year of follow-up. The study includes patients who received either PFA or RFA one year ago and tracks their outcomes over time. The study involves two groups of patients one treated with PFA using a force-sensing PFA catheter and the other with RFA using force-sensing RFA catheters. Data from 214 patients who received PFA and 214 matched patients who received RFA were collected from multiple hospitals between October 2022 and June 2024. Researchers analyzed clinical information, procedural data, and safety and effectiveness outcomes for one year after treatment. Participants were followed up at 1, 3, 6, and 12 months after their ablation procedures with examinations and blood tests. Researchers measured the success rate shortly after the procedure and at one year, as well as the occurrence of serious and non-serious adverse events during and after the treatments. The study helps to understand the safety and effectiveness of these two ablation methods for PSVT over the long term.
