January 31, 2025 updated by: Biosense Webster, Inc.

Exploratory Safety and Effectiveness Evaluation of Pulsed Field Ablation by a Balloon Catheter With the TRUPULSE Generator for Treatment of Paroxysmal Atrial Fibrillation (PAF)

The purpose of this study is to explore preliminary safety and acute effectiveness of pulsed field ablation by the ablation system (pulsed field ablation balloon catheter and TRUPULSE generator) when used for isolation of the atrial pulmonary veins (PVs) in treatment of participants with paroxysmal atrial fibrillation (PAF), an irregular heart rate that causes abnormal blood flow.

Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Diagnosed with symptomatic Paroxysmal Atrial Fibrillation (PAF) defined as AF that terminates spontaneously or with intervention within 7 days of onset. This PAF is considered to be symptomatic if symptoms related to AF are experienced by the participant
  • Selected for AF ablation procedure by pulmonary vein isolation (PVI)
  • Willing and capable of providing consent
  • Able and willing to comply with all pre-, post-, and follow-up testing and requirements

Exclusion Criteria:

  • Previously known AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (example, documented obstructive sleep apnea, acute alcohol toxicity, morbid obesity [body mass index more than {>} 40 kilogram per square meter {kg/m^2}], renal insufficiency [with an estimated creatinine clearance less than {<}30 milliliter {mL}/minute {min}/1.73 meter {m}^2])
  • Previous left atrium (LA) ablation or surgery
  • Participants known to require ablation outside the pulmonary vein (PV) region (example, atrioventricular reentrant tachycardia, atrioventricular nodal re-entry tachycardia, atrial tachycardia, ventricular tachycardia and Wolff-Parkinson-White)
  • Previously diagnosed with persistent AF (>7 days in duration)
  • Severe dilatation of the LA (left anterior descending artery [LAD] >50 millimetre [mm] antero-posterior diameter or left atrium volume index [LAVi] >48 [mL/m^2] in case of transthoracic echocardiography [TTE])

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Pulsed Field Ablation by a Balloon Catheter with the TRUPULSE Generator
Participants with paroxysmal atrial fibrillation (PAF) will undergo pulmonary vein (PV) ablation procedure with investigational system (pulsed field ablation balloon catheter used in combination with the TRUPULSE generator) until pulmonary vein isolation (PVI) is achieved and confirmed via entrance block. If PVI cannot be achieved with the investigational system, a commercially approved Biosense Webster (recommended) catheter and compatible commercially available generator can be used to complete the procedure.
Device: Pulsed Field Ablation by a Balloon Catheter with the TRUPULSE Generator
Pulsed field ablation balloon catheter and TRUPULSE generator will be used for PV ablation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants with Primary Adverse Events (PAEs)
Time Frame: Up to 3 months post-procedure
Percentage of participants with PAEs will be reported. PAE's will include the following adverse events: atrio-esophageal fistula, phrenic nerve paralysis, cardiac tamponade/perforation, severe pulmonary vein stenosis (PVS), device or procedure related death, stroke/cerebrovascular accident (CVA), major vascular access complication/bleeding, thromboembolism, myocardial infarction, transient ischemic attack (TIA), pericarditis, heart block, pulmonary edema (respiratory insufficiency), and vagal nerve injury/gastroparesis.
Up to 3 months post-procedure
Percentage of Participants with Acute Effectiveness
Time Frame: Up to 3 months post-procedure
Percentage of participants with acute effectiveness will be reported. Acute effectiveness is an electrical isolation of clinically relevant targeted pulmonary veins (PVs) which is evidenced by confirmation of entrance block, after adenosine/isoproterenol challenge, at the end of the index ablation procedure.
Up to 3 months post-procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants with Freedom from Documented (Symptomatic and Asymptomatic) Atrial Arrhythmia (Atrial Fibrillation [AF], Atrial Tachycardia [AT] or Atrial Flutter [AFL] of Unknown Origin) Episodes During the Effectiveness Evaluation Period
Time Frame: Within Day 91 to Day 365
Percentage of participants with freedom from documented (symptomatic and asymptomatic) atrial arrhythmia (AF, AT or AFL of unknown origin) episodes based on electrocardiographic data (more than equal to [>=]30 seconds on arrhythmia monitoring device) during the effectiveness evaluation period (Day 91 to Day 365) on or off antiarrhythmic therapy will be reported. Acute procedural failure (that is, failure to achieve entrance block with the study device in any of the clinically relevant targeted PVs) will also be deemed a 12-month effectiveness failure.
Within Day 91 to Day 365
Percentage of PVs that are Targeted in the Index Ablation Procedure with Sustained Isolation at Day 75
Time Frame: Day 75
Percentage of PVs that are targeted in the index ablation procedure with sustained isolation, which is evidenced by electrical confirmation (through pacing for entrance block) of isolation at Day 75 post index ablation procedure will be reported.
Day 75
