AN OVERVIEW OF HOW WATCHMAN WORKS


  • The WATCHMAN Implant procedure usually lasts about an hour and the patient is typically in the hospital for a day
  • The WATCHMAN Implant procedure is typically performed under general anesthesia in a catheterization laboratory setting using a standard transseptal technique
  • A transesophageal echocardiogram (TEE) is performed to measure the left atrial appendage (LAA) to determine which size WATCHMAN Device to be implanted
  • After the interatrial septum is crossed using a standard transseptal access system, the WATCHMAN Access Sheath is advanced over a guidewire into the left atrium. The Access Sheath is then advanced into the distal portion of the LAA over a pigtail catheter
  • The WATCHMAN Delivery System is prepped, inserted into the Access Sheath, and slowly advanced under fluoroscopic guidance. WATCHMAN is then deployed into the LAA. The device release criteria are confirmed via fluoroscopy and TEE prior to releasing the device
  • By closing off the LAA, the risk of stroke may be reduced and, over time, patients may be able to stop taking anticoagulants

IN THE PREVAIL TRIAL, WATCHMAN WAS IMPLANTED SUCCESSFULLY IN 95% OF PATIENTS1*


The animation below shows how the WATCHMAN device is implanted in the left atrial appendage. Video length: approximately 3 minutes.

*Reasons for aborted implantation attempts were: the patient did not stop anticoagulation before the procedure; pre-implant transesophageal echocardiography (TEE) revealed a new LAA thrombus; LAA size and shape were not optimal for the device; and occurrence of an adverse event that forced the procedure to stop.1

THE WATCHMAN IMPLANT IS THE ONLY FDA-APPROVED DEVICE PROVEN TO SAFELY AND EFFECTIVELY REDUCE STROKE RISK IN PATIENTS WITH NVAF


  • Procedural complication rates of only 4.2% were reported in the PREVAIL randomized controlled trial for both new and experienced operators
    • Procedure-related complications were defined as a composite of cardiac perforation, pericardial effusion with tamponade, ischemic stroke, device embolization, and other vascular complications occurring in the first 7 days after implant

THE WATCHMAN IMPLANT IS IN USE AT TOP MEDICAL INSTITUTIONS ACROSS THE COUNTRY


  • More than 150 major medical centers across the US are certified to implant WATCHMAN
  • The WATCHMAN physician training program involves multiple phases including didactic training, imaging training, training in patient selection, device selection, complication management, and optional physician proctoring
    • Individual physicians and/or the collective physician-team must be proficient in transseptal skills prior to entering the WATCHMAN Training Program
