Left Atrial Appendage Closure Device
WATCHMAN FLX is now FDA APPROVED for use in nonvalvular atrial fibrillation patients who are eligible for anticoagulation therapy.
Built on the most studied and implanted LAAC device in the world, WATCHMAN FLX is designed to advance procedural performance and safety while expanding the treatable patient population.
PINNACLE FLX Clinical Study
- 400 patient, 29 US site, single arm, non-randomized trial evaluating WATCHMAN FLX for non-inferiority to safety and efficacy performance goals based on the WATCHMAN™ device.
- Follow-up: 45 days (+TEE), 6 months, 12 months (+TEE), 18 months, and 24 months
- Patient Characteristics: Average CHA2DS2-VASc of 4.2±1.5, Average HAS-BLED of 2.0±1.0
- Post Implant Drug Regimen: NOAC/ASA for 45 days, Clopidogrel/ASA to 6 months, ASA post 6 months
- Primary Safety Endpoint: All-cause death, ischemic stroke, systemic embolism, or device- or procedure-related adverse events requiring surgery or major endovascular intervention within 7 days following the procedure or by hospital discharge, whichever is later.
- Primary Efficacy Endpoint: The rate of effective LAA closure defined as any peri-device flow ≤5mm demonstrated by TEE at 12 months
- Secondary Efficacy Endpoint: The occurrence of ischemic stroke or systemic embolism at 24 months from the time of enrollment
- Inclusion/exclusion criteria is consistent with WATCHMAN clinical study inclusion/exclusion criteria. Patients must be eligible for short-term NOAC vs warfarin in previous clinical studies.
