Uno studio del catetere VARIPULSE per ablazione a campo pulsato (PFA) e del catetere FARAWAVE PFA nel trattamento di partecipanti con fibrillazione atriale persistente (PERSIGMA RCT)

2 novembre 2026 aggiornato da: Biosense Webster, Inc.

Confronto della sicurezza e dell'efficacia del catetere VARIPULSE™ PFA rispetto al catetere FARAWAVE™ PFA nel trattamento dei partecipanti con fibrillazione atriale persistente: uno studio randomizzato controllato

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).

Descrizione

Inclusion criteria:

A physician's note documenting diagnosis of symptomatic PsAF as defined above and ii. Two electrocardiograms showing continuous AF, with electrocardiogram taken at least 7 days apart (electrocardiograms cannot be greater than [>] 365 days prior to enrollment) or iii. 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 is willing and capable of providing informed consent
  • Participant is able and willing to comply with all pre-, post- and follow-up testing and requirements

Exclusion criteria:

  • Participant has continuous AF > 365 days (longstanding persistent AF)
  • Participant has AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (for example, untreated documented obstructive sleep apnea, acute alcohol toxicity, etc.)
  • Participant has had previous surgical or catheter ablation for AF
  • Participant is known to require ablation outside the left atrium (LA), superior vena cava (SVC), and the cavotricuspid isthmus (CTI) region (for example, atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia, ventricular tachycardia and Wolff-Parkinson-White)
  • Participant has severe dilatation of the LA (LAD > 50 millimeters [mm]) of the antero-posterior diameter confirmed by imaging performed within 180 days prior to enrollment

  • Participant has had coronary artery bypass grafting (CABG) surgery within the past 180 days prior to enrollment

  • 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 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
  • Participant has a life expectancy less than 365 days

For magnetic resonance imaging (MRI) subset:

  • Contraindication to use of contrast agents for MRI such as advanced renal disease etcetera
  • Presence of iron-containing metal fragments in the body that renders the participant contraindicated for an MRI

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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.

Comparatore attivo: 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.

Time to Occurrence of Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia Episodes
Lasso di tempo: Day 61 and onward

Time to occurrence of documented (symptomatic and asymptomatic) atrial tachyarrhythmia (atrial fibrillation [AF], atrial tachycardia [AT] or atrial flutter [AFL] of unknown origin) episodes based on electrocardiographic data (12-Lead Electrocardiogram (ECG) or greater than equal to (>=) 30 seconds on sponsor provided Cardiac Event Monitor (CEM) or Patch arrhythmia monitor) during the effectiveness evaluation period or acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, non-study catheter (NSC) failure, antiarrhythmic drug (AAD) failure and any direct current cardioversion (DCCV) procedure.

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) Score
Lasso di tempo: 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.
