En undersøgelse af VARIPULSE Pulsed Field Ablation (PFA)-kateter og FARAWAVE PFA-kateter i behandlingen af deltagere med persisterende atrieflimren (PERSIGMA RCT)

2. november 2026 opdateret af: Biosense Webster, Inc.

Sammenligning af sikkerhed og effektivitet af en VARIPULSE™ PFA-kateter med FARAWAVE™ PFA-kateter i behandlingen af deltagere med vedvarende atrieflimren: Et randomiseret kontrolleret forsøg

The purpose of this study is to assess how safe VARIPULSE pulsed field ablation (PFA) catheter is and how well it works compared to food and drug administration (FDA) approved FARAWAVE PFA catheter in participants with symptomatic persistent atrial fibrillation (PsAF; continuous irregular, rapid heartbeat that lasts over 7 days and doesn't stop on its own).

A 24-hour arrhythmia monitor documenting continuous AF within the last 365 days
  • Participant is aged 18 - 80 years at the time of informed consent

  • Participant has significant pulmonary disease (for example, restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms
  • Participant has a significant congenital anomaly (for example, atrial septal defects [ASDs]) including repaired defects or medical problems that in the opinion of the Investigator would preclude enrollment in this study
  • Participant has an existing diagnosis of pulmonary vein stenosis (PVS)
  • Participant has a pre-existing hemi-diaphragmatic paralysis
  • Participant has an acute illness, active systemic infection, or sepsis
  • Participant has an intracardiac thrombus, myxoma, tumor, interatrial baffle or patch or other abnormality that precludes catheter introduction or manipulation
  • Participant has severe mitral regurgitation (regurgitant volume greater than or equal to [>=] 60 milliliters [mL]/beat, regurgitant fraction >= 50 percent [%], and/or effective regurgitant orifice area >= 0.40 square centimeter [cm^2])
  • Participant has an implanted metal cardiac device, including MitraClip and left atrial appendage occlusion (LAAO) devices (for example, WATCHMAN, Amulet, etcetra.) and/or a double-coiled implantable cardioverter-defibrillators (ICD), (this exclusion does not include coronary stents, implanted pacemakers, single-coiled ICD and implantable loop recorders [ILR])
  • Participant has a condition that precludes vascular access (such as inferior vena cava [IVC] filter)
  • Participant is currently enrolled in an investigational study evaluating another device or drug
  • Participant is pregnant, lactating, or is of child-bearing potential and plans on trying to become pregnant during the course of the clinical investigation

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: VARIPULSE Pulsed Field Ablation (PFA) Catheter

Participants with persistent atrial fibrillation (PsAF) undergoing catheter ablation will undergo the ablation procedure with VARIPULSE catheter, and will be followed for up to 12 months post procedure. Eligible participants may enter an magnetic resonance imaging (MRI) subset and undergo MRI assessments at baseline and post-ablation procedure.

Aktiv komparator: FARAWAVE PFA Catheter

Participants with PsAF undergoing catheter ablation will undergo the ablation procedure with FARAWAVE catheter, and will be followed for up to 12 months post procedure. Eligible participants may enter an MRI subset and undergo MRI assessments at baseline and post-ablation procedure.

Tidsramme
Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) Score
Tidsramme: Baseline and at 6 months post procedure

The AFEQT uses a questionnaire to evaluate symptoms, daily activities and treatment concerns participants have related to atrial fibrillation. An overall AFEQT score ranges from 0 to 100. A score of 0 corresponds to complete disability (or responding "extremely" difficult to all questions answered), while a score of 100 corresponds to no disability (or responding "not at all" limited, difficult or bothersome to all questions answered). A positive change in score corresponds to improvement in AF symptoms.
