May 22, 2025 updated by: Biosense Webster, Inc.

Pulsed Field Ablation (PFA) System for the Treatment of Paroxysmal Atrial Fibrillation (PAF) by Irreversible Electroporation (IRE)

The primary objective is to demonstrate safety and long-term effectiveness of the irreversible electroporation (IRE) system (Circular IRE Catheter and IRE Generator) when used for isolation of the atrial pulmonary veins (PVs) in treatment of participants with paroxysmal atrial fibrillation (PAF).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Diagnosed with Symptomatic paroxysmal atrial fibrillation (PAF)
  • Selected for atrial fibrillation (AF) ablation procedure by pulmonary vein isolation (PVI)
  • Failed at least one antiarrhythmic drug (AAD) (class I to IV) as evidenced by recurrent symptomatic atrial fibrillation AF, or intolerable or contraindicated to the AAD
  • Willing and capable of providing consent
  • Able and willing to comply with all pre-, post- and follow-up testing and requirements

Exclusion Criteria:

  • AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
  • Previous left atrium (LA) ablation or surgery
  • Participant known to require ablation outside the PV region (example. cavotricuspid isthmus [CTI] region, atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia, atrial tachycardia, ventricular tachycardia and Wolff-Parkinson-White)
  • Previously diagnosed with persistent AF (greater than [>] 7 days in duration)
  • Severe dilatation of the LA (LAD >50 millimeter (mm) antero-posterior diameter in case of transthoracic echocardiography (TTE))

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Participants with Paroxysmal Atrial Fibrillation (PAF)
Participants with PAF and who are candidates for catheter ablation will be enrolled.
Participants will undergo PFA therapy with a compatible ablation catheter when used with Multi-Channel irreversible electroporation (IRE) Generator (deliver trains of high-voltage bipolar pulses of short duration on separate channels to a multi-electrode ablation catheter) and Circular IRE Catheter (indicated for use in catheter-based cardiac electrophysiological mapping (stimulating and recording) and, when used with an IRE Generator, for cardiac ablation).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Primary Adverse Events (PAEs)
Time Frame: Within 7 days post-procedure on Day 0
An adverse event (AE) is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. The primary safety endpoint was the incidence of PAEs (within 7 days of the initial mapping and ablation procedure). PAEs included the following AEs: Atrio-esophageal fistula, cardiac tamponade/perforation, device or procedure related death, major vascular access complication/bleeding, myocardial infarction, pericarditis, phrenic nerve paralysis (permanent), pulmonary vein stenosis, stroke/cerebrovascular accident (CVA), thromboembolism, and transient ischemic attack (TIA).
Within 7 days post-procedure on Day 0
Kaplan-Meier Estimates of the Success Rate of Freedom From Documented (Symptomatic and Asymptomatic) Atrial Arrhythmia (Atrial Fibrillation [AF], Atrial Tachycardia [AT], or Atrial Flutter [AFL]) Episodes From Day 91 to Day 365 Post Index Procedure
Time Frame: From Day 91 up to Day 365 post index procedure on Day 0
Kaplan-Meier estimates of the success rate of freedom from primary effectiveness failure, that is, documented (symptomatic and asymptomatic) atrial arrhythmia (AF, AT, or AFL) recurrence based on electrocardiographic data (>=30 seconds on arrhythmia monitoring device) from Day 91 to Day 365 post index procedure, was reported. Acute procedural failure defined as failure to confirm entrance block in all PVs except those that are silent and/or cannot be cannulated post-procedure, use of a non-study catheter for PV isolation, or failure to have PFA delivery with the study catheter due to IRE system malfunctions, was also considered a long-term effectiveness failure.
From Day 91 up to Day 365 post index procedure on Day 0

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Who Achieved Acute Procedural Success
Time Frame: Day 0 (Day of procedure)
Number of participants who achieved acute procedural success were reported. Acute procedural success was defined as confirmation of entrance block in all clinically relevant targeted pulmonary veins (PVs) after adenosine/ isoproterenol challenge.
Day 0 (Day of procedure)
Kaplan-Meier Estimates of the Success Rate of Freedom From Documented Symptomatic Re-Occurrence of Atrial Arrhythmia (Atrial Fibrillation [AF], Atrial Tachycardia [AT], or Atrial Flutter [AFL]) Episodes From Day 91 to Day 365 Post Index Procedure
Time Frame: From Day 91 up to Day 365 post index procedure on Day 0
Kaplan-Meier estimates of the success rate of freedom from primary effectiveness failure, that is, documented symptomatic re-occurrence of atrial arrhythmia (AF, AT, or AFL) episodes based on electrocardiographic data (>=30 seconds on arrhythmia monitoring device) from Day 91 to Day 365 post index procedure, was reported. Acute procedural failure defined as failure to confirm entrance block in all PVs except those that are silent and/or cannot be cannulated post-procedure, use of a non-study catheter for PV isolation, or failure to have PFA delivery with the study catheter due to IRE system malfunctions, was also considered a long-term effectiveness failure.
From Day 91 up to Day 365 post index procedure on Day 0
Change From Baseline in Atrial Fibrillation Effect on Quality of Life (AFEQT) Total Score
Time Frame: Baseline, Months 3, 6, and 12
Change from baseline in AFEQT total score was reported. The AFEQT questionnaire is an atrial fibrillation-specific health-related quality of life (HRQoL) questionnaire designed to assess the impact of atrial fibrillation on participants' HRQoL. The questionnaire includes 20 questions on a 7-point Likert scale. Questions 1-18 evaluate HRQoL and questions 19-20 relate to participants' satisfaction with treatment. Overall or subscale scores range from 0 to 100, where 0 corresponds to complete disability (or responding "extremely" limited, difficult or bothersome 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). Therefore, a positive change in score corresponds to improvement in QoL. Total score was calculated using AFEQT formula: 100 -([sum of severity for all questions answered - number of questions answered]*100 / total number questions answered*6).
