Concomitant Pulsed Field Ablation and Left Atrial Appendage Closure in AF Patients

Official title: Concomitant Left Atrial Appendage Closure and Pulsed Field Ablation - Europe, Middle East and Africa [OPTION-EMEA]

Run by Boston Scientific Corporation · NCT07349121 · Data updated 2026-11-12

In patients with atrial fibrillation who need both ablation and left atrial appendage closure, this study tests doing both procedures in a single intervention using FARAPULSE PFA and a WATCHMAN FLX device.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with atrial fibrillation indicated for both FARAPULSE PFA and WATCHMAN FLX LAAC, treated per standard of care by their physician.

Probably not a fit

Patients whose anatomy or medical condition makes LAAC or PFA unsuitable or whose AF is due to non-cardiac reversible causes may not benefit.

What this trial studies

This post-market study collects real-world data on patients undergoing atrial fibrillation ablation with the FARAPULSE pulsed field ablation system followed by left atrial appendage closure with a WATCHMAN FLX device in the same procedure. Eligible patients are treated per their physician’s judgment as part of standard care, and data are gathered from approved investigational centers. The protocol specifies concomitant PFA and LAAC in a single interventional case, with follow-up testing as required by the study. Enrollment is limited to adults able to provide informed consent who meet the device indications and institutional requirements. The sponsor is Boston Scientific Corporation, with participating sites in Europe (Belgium and Croatia).

Why it matters

Potential benefit: If successful, the approach could streamline AF treatment by combining ablation and LAAC in one procedure, potentially reducing procedure time and recovery for some patients.

How similar studies have gone: Prior use of combined ablation and LAAC approaches has shown promise in observational settings, but this exact concomitant PFA-LAAC strategy is novel/less established.

2. Subjects who are willing and able to provide informed consent.
3. Subjects who are willing and able to participate in all testing associated with this clinical study at an approved investigational center.
4. Subjects whose age is 18 years or above, or who are of legal age to give informed consent specific to state and national law.

Exclusion Criteria:

1. Subjects who underwent prior AF ablation procedure.
2. Subjects with atrial fibrillation that is secondary to electrolyte imbalance, thyroid disease, alcohol, or other reversible / non-cardiac causes.
3. Already surgically closed or otherwise excluded LAA.
4. The LAA anatomy does not accommodate a Closure Device.
5. Known or suspected atrial myxoma.
6. Presence of intracardiac thrombus\*.
7. Subjects with a current interatrial baffle or patch, history of atrial septal repair or has an atrial septal defect (ASD) / patent foramen ovale (PFO) device.
8. Subjects with a presence of a mechanical valve prosthesis in any position.
9. Subjects with a myocardial infarction within 90 days prior to enrollment.
10. Subjects had a prior stroke (of any cause, whether ischemic or hemorrhagic) or transient ischemic attack (TIA) within 90 days prior to enrollment.
11. Any planned electrical cardioversion within 30 days following LAAC device implant.
12. Subjects with a known inability to obtain vascular access.
13. Subjects with any contraindication to percutaneous catheterization procedure (e.g., patient size does not accommodate required catheters, ventriculotomy or atriotomy) or congenital abnormalities (severe rotational anomalies of the heart or great vessels) are present.
14. Subjects with any active conditions (e.g. infection, bleeding disorder, unstable angina).
15. Subjects with any contraindications to short term use of anticoagulation therapy for conditions different from atrial fibrillation.
16. Subjects who are pregnant or planning to be pregnant.
17. Subjects with a life expectancy of ≤ 1 year per investigator's opinion.
18. Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments. Each instance must be reviewed by the sponsor to determine eligibility.
