Long-term safety and effectiveness of the VARIPULSE catheter system for treating atrial fibrillation
Official title: BWI202405: Assessment of Long-Term Safety and Effectiveness in Treatment Management of Atrial Fibrillation With the VARIPULSE™ Catheter System
Run by Biosense Webster, Inc. · NCT07227532 · Data updated 2026-11-12
This will test whether the VARIPULSE pulsed‑field ablation catheter is safe and effective long‑term for people with symptomatic paroxysmal atrial fibrillation who need pulmonary vein isolation.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with symptomatic paroxysmal atrial fibrillation who are considered appropriate for catheter ablation and who are refractory to, intolerant of, or have contraindications to at least one Class I/III antiarrhythmic medication.
✕Probably not a fit
Patients with persistent or long‑standing persistent AF, prior surgical or catheter AF ablation, significant contraindicating medical problems, or life expectancy under 12 months are unlikely to benefit from this protocol.

What this trial studies
This interventional study uses the VARIPULSE pulsed‑field ablation catheter with the TRUPULSE generator to perform pulmonary vein isolation in patients with symptomatic paroxysmal atrial fibrillation. Participants are typically those who are candidates for catheter ablation and who are refractory to, intolerant of, or have contraindications to at least one Class I/III antiarrhythmic drug. The trial follows patients over the long term to document safety outcomes and durability of rhythm control after the procedure. Key exclusions include prior AF ablation, persistent or long‑standing persistent AF, significant contraindicating medical conditions, and limited life expectancy.
Why it matters
Potential benefit: If successful, this could provide a durable, long‑term treatment option that reduces AF recurrence while maintaining a favorable safety profile for people with paroxysmal AF.
How similar studies have gone: Pulsed‑field ablation techniques, including the VARIPULSE system, have shown promising acute safety and pulmonary vein isolation results in prior studies and the device is FDA‑approved, but robust long‑term effectiveness data are still being gathered.

Inclusion Criteria: * Symptomatic paroxysmal Atrial Fibrillation (AF) who, in the opinion of the investigator, are candidates for catheter ablation for AF * Refractory (that is, ineffective, not tolerated, or not desired) or contraindicated to at least one Class I/III antiarrhythmic drugs (AAD) * Willing and capable of providing consent * Able and willing to comply with all pre-, post-, and follow-up testing and requirements Exclusion Criteria: * Previously diagnosed with persistent or long-standing persistent AF (more than \[\>\] 7 days in duration) * Previous surgical or catheter ablation for AF * Significant congenital anomaly or medical problem that in the opinion of the investigator would be a contraindication to catheter ablation for AF * Current enrollment in an investigational study evaluating another device or drug * Life expectancy less than 12 months * Any contraindications as defined in the Protocol
