- No healthy volunteers
- Adult, Older adult

About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pulsed Field Ablation by a Balloon Catheter with the TRUPULSE GeneratorDevice
Pulsed field ablation balloon catheter and TRUPULSE generator will be used for PV ablation.
| Study group | Role | What they receive |
|---|---|---|
| Pulsed Field Ablation by a Balloon Catheter with the TRUPULSE Generator | Experimental | 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. Receives: Device: Pulsed Field Ablation by a Balloon Catheter with the TRUPULSE Generator |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants with Primary Adverse Events (PAEs)
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.
Measured: Up to 3 months post-procedure
Percentage of Participants with Acute Effectiveness
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.
Measured: Up to 3 months post-procedure
Secondary outcomes (2)
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
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.
Measured: Within Day 91 to Day 365
Percentage of PVs that are Targeted in the Index Ablation Procedure with Sustained Isolation at 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.
Measured: Day 75

The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2025.
