Watchman Device

Left Atrial Appendage Closure (LAAC)

A one-time, minimally invasive procedure that can reduce stroke risk in atrial fibrillation patients and eliminate the need for long-term blood thinners.

What is the Watchman Device?

The Watchman is an FDA-approved implant about the size of a quarter that permanently closes off the left atrial appendage (LAA) — a small pouch in the heart where blood clots commonly form in people with atrial fibrillation (AFib). By sealing off this area, the Watchman significantly reduces stroke risk without the need for long-term blood thinners.

For many AFib patients, blood thinners (anticoagulants) like warfarin are prescribed to prevent clots and reduce stroke risk. However, blood thinners come with their own risks, including bleeding complications. The Watchman offers an alternative for patients who have difficulty with or concerns about long-term anticoagulation.

Understanding Atrial Fibrillation & Stroke Risk

Atrial fibrillation (AFib) is an irregular heart rhythm that affects millions of Americans. During AFib:

  • The heart's upper chambers (atria) quiver instead of beating effectively
  • Blood can pool and form clots, especially in the left atrial appendage
  • Clots can travel to the brain and cause a stroke
  • Over 90% of stroke-causing clots in AFib form in the left atrial appendage

Did you know? People with AFib are 5 times more likely to have a stroke than those without AFib, and AFib-related strokes tend to be more severe.

Who is a Candidate for Watchman?

The Watchman device may be right for you if:

  • You have atrial fibrillation not caused by a heart valve problem
  • You need an alternative to blood thinners for stroke prevention
  • You have a history of bleeding problems while on blood thinners
  • Your lifestyle, occupation, or activities put you at higher bleeding risk
  • You have difficulty managing blood thinner medication (frequent monitoring, diet restrictions)
  • You cannot tolerate long-term anticoagulation therapy

The Watchman Procedure

1

Preparation

You'll receive general anesthesia. A transesophageal echocardiogram (TEE) is used throughout the procedure to guide placement.

2

Access

A catheter is inserted through a vein in the leg and guided to the heart. A small puncture is made in the wall between the heart's upper chambers to reach the left atrial appendage.

3

Implantation

The Watchman device is positioned at the opening of the left atrial appendage. Once properly positioned, it is released from the catheter.

4

Verification

Imaging confirms the device is properly placed and sealing the appendage. The catheter is then removed.

After the Procedure

Short-Term Recovery

  • Most patients go home the next day
  • Return to normal activities within a few days
  • Short-term blood thinner use for about 45 days

Long-Term Benefits

  • 96% of patients discontinue blood thinners within 1 year
  • No dietary restrictions from blood thinner medication
  • Reduced bleeding risk over time

Frequently Asked Questions About Watchman

What is the Watchman device and how does it work?

The Watchman is an FDA-approved implant about the size of a quarter that permanently closes off the left atrial appendage (LAA) in the heart. In patients with atrial fibrillation, over 90% of stroke-causing blood clots form in the LAA. By sealing this area, the Watchman significantly reduces stroke risk without requiring long-term blood thinners.

Can I stop taking blood thinners after Watchman?

Yes, most patients can stop blood thinners after the Watchman procedure. You'll take blood thinners for about 45 days while tissue grows over the device. After a follow-up imaging test confirms the LAA is sealed, most patients transition to aspirin only. Clinical studies show 96% of patients are off blood thinners within one year.

What is the success rate of Watchman implantation?

The Watchman procedure has a very high success rate, with over 95% of implants successfully placed in clinical trials. The device has been implanted in over 150,000 patients worldwide. Long-term studies show it provides stroke protection comparable to blood thinners while reducing bleeding risk over time.

How long is the Watchman procedure and recovery?

The Watchman procedure typically takes about one hour. Most patients stay overnight in the hospital and go home the next day. You can return to normal activities within a few days. The small groin puncture site heals quickly, and most patients experience minimal discomfort.

Who is a good candidate for the Watchman device?

Watchman is designed for people with atrial fibrillation (not caused by a heart valve problem) who need an alternative to long-term blood thinners. Good candidates often have a history of bleeding, fall risk, active lifestyle concerns, or difficulty managing blood thinner medications. Your cardiologist can evaluate if Watchman is right for you.
