Detailed Description

The OPTION-A Study is an observational, prospective, single-arm, multi-center non-mandated post-market study. Subjects enrolled in the OPTION-A study will be clinically indicated for atrial fibrillation (AF) ablation procedure with the FARAPULSE PFA system and treatment with WATCHMAN LAAC Device, per physician's medical judgement and according to hospitals' standard of care. The objective(s) of the OPTION-A Study is to evaluate safety and effectiveness of catheter ablation with the FARAPULSE™ Pulsed Field Ablation (PFA) System and subsequent implant of Left Atrial Appendage closure (LAAC) with the WATCHMAN™ LAA Closure device in a concomitant procedure.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

• Sampling Method: Non-Probability Sample

Study Population

Subjects enrolled in the OPTION-A study will be clinically indicated for an Atrial Fibrillation ablation procedure utilizing the FARAPULSE PFA System as well as implantation of the WATCHMAN device per physician's medical judgement, and according to the hospitals' standard of care during the same procedure. The subjects selected for participation in the study will be from the investigator's general patient population. The investigator or designee has the responsibility for screening all potential subjects and selecting those who meet study eligibility criteria.

Description

Inclusion Criteria:

1. Clinically indicated for treatment with both the FARAPULSE™ PFA system and with WATCHMAN for LAAC, per physician medical judgement and as per hospitals' standard of care.
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 clinical 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.

10. Subjects had a prior stroke (of any cause, whether ischemic or hemorrhagic) or transient ischemic attack (TIA) within the 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), active conditions (e.g. infection, bleeding disorder, unstable angina) 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) are present.
15. Subjects with any contraindications to short term use of anticoagulation therapy, or aspirin for conditions different from atrial fibrillation.

Cohorts and Interventions

Group / Cohort

Intervention / Treatment

Treatment Subjects; A subject is considered enrolled once an approved informed consent form has been signed and dated. Enrolled Subjects will undergo AF ablation procedure with the FARAPULSE PFA System, followed by WATCHMAN implant during the same procedure.

Device: FARAPULSE™ PFA system and WATCHMAN LAAC Delivery Systems; The FARAPULSE™ PFA System consists of the FARAWAVE™ Pulsed Field Ablation Catheter, the FARASTAR™ Pulsed Field Ablation Generator, and the FARADRIVE™ Steerable Sheath. The WATCHMAN LAA Closure Technology consists of the WATCHMAN Access System (which consists of the Access Sheath and Dilator and the WATCHMAN Delivery System (which consists of the delivery catheter and the pre-loaded closure device). The WATCHMAN Access System and WATCHMAN Delivery System permit device placement in the LAA via femoral venous access and crossing the inter-atrial septum into the left atrium.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Periprocedural or procedure-related Composite Serious Adverse Events will be assessed	The primary safety endpoint (PSE) is the proportion of subjects with one or more of the periprocedural device or procedure-related Composite Serious Adverse Events (CSAEs) assessed at 30 days following the Index Procedure.	30 days post index procedure
Acute Treatment Success will be assessed	The primary effectiveness endpoint (PEE) is the proportion of subjects with Acute Treatment Success assessed among those receiving ≥1 PFA application and who have a WATCHMAN attempted or implanted.	between index procedure and 30 days post index procedure

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Device or procedure-related Composite Serious Adverse Events (CSAEs) assessed	Device or procedure-related Composite Serious Adverse Events (CSAEs) assessed at 360 days following the Index Procedure	1 year post index procedure
