Effectiveness Study of VARIPULSE Catheter and TRUPULSE Generator Using VARIPULSE Pro Software to Treat Paroxysmal and Persistent Atrial Fibrillation

What this Trial Is About

Researchers are evaluating the use of the pulsed field ablation system, which includes the VARIPULSE Catheter, TRUPULSE Generator, and the new VARIPULSE Pro software, for treating participants with paroxysmal atrial fibrillation PAF and persistent atrial fibrillation PsAF. The study focuses on the workflow effectiveness of this system during cardiac ablation procedures aimed at managing irregular heartbeats in these populations. Participants will undergo pulsed field ablation PFA using the VARIPULSE Catheter and TRUPULSE Generator with the VARIPULSE Pro software. The study involves a single group receiving this device-based intervention to treat symptomatic PsAF or PAF through pulmonary vein isolation PVI alone or combined with cavotricuspid isthmus-dependent atrial flutter ablation. The treatment is delivered during an ablation procedure with the device system. During the study, participants will be monitored for various outcomes including acute effectiveness during the procedure, durability of pulmonary vein isolation at 3 months, and procedural details such as pulsed field application time and number of applications. Safety assessments include monitoring for serious and non-serious adverse events up to 3 months post-procedure, neurological evaluations using MRI and cognitive scales, and assessment of pulmonary vein stenosis. The total participation duration extends at least 3 months post ablation for follow-up and outcome measurement.
