WATCHMAN™ Left Atrial Appendage Closure

Watchman Left Atrial Appendage ClosureThe WATCHMAN Left Atrial Appendage Closure (LAAC) is an implant-based alternative to blood thinners for patients with Atrial Fibrillation (AFib) not caused by a heart valve problem. When a blood clot develops in the heart of a patient with AFib, it is most often found within the left atrial appendage, a small pouch on top of the heart. An LAAC implant acts as a barrier to prevent left atrial appendage blood clots from entering the bloodstream and causing a stroke.

Watchman Implant - Size of a QuarterIt is important to know that a stroke can be due to factors not related to a clot travelling to the brain from the let atrial appendages. Other causes of stroke include: high blood pressure, and narrowing of the blood vessels to the brain. An LAAC implant does not prevent these other causes of stroke.

It is also important to understand that, like blood-thinning medications, an LAAC implant does not cure AFib.

Specific factors that need to be considered for the WATCHMAN Device and implantation procedure include:

  • Overall medical status, including conditions which might preclude the safety of a percutaneous, transcatheter procedure.
  • Suitability for percutaneous, trans-septal procedures, including  considerations of:
    • cardiac anatomy relating to LAA size and shape
      vascular access anatomy
    • ability to tolerate general or local anesthesia
    • ability to undergo required imaging
    • ability to comply with recommended post-WATCHMAN Device implant
    • pharmacologic regimen
    • Warfarin plus aspirin for at least 45 days post-device implantation
      Clopidogrel and aspirin through six months post-procedure
    • Aspirin indefinitely
