The Watchman, or the left atrial appendage closure implant, is the size of a quarter and closes off this part of the heart where blood clots are formed.

During the Watchman Implant procedure, your doctor will make a small incision in your leg and insert a narrow tube. The Watchman will be guided through the tube and placed into your left atrial appendage. Heart tissue will grow over the implant to form a barrier against blood clots over time and the left atrial appendage will eventually close permanently.

What to Expect During your Visit

  • You will undergo general anesthesia during the procedure. The procedure is not open heart surgery.
  • You can expect to stay in the hospital overnight and go home the next day.
  • After 45 days, the left atrial appendage should be completely sealed, thus preventing blood clots from being created and escaping.
