Watchman Device

Preventing stroke is one of the most important aspects of atrial fibrillation (AFib) care at Valley. While many patients take blood thinners to lower their risk, Valley also offers the Watchman device for certain patients.

The Watchman is an implant that helps prevent stroke in people who have AFib not caused by heart valve problems. This can be an alternative to lifelong use of blood thinner medicines for certain people.

Valley’s electrophysiology team has vast experience in left atrial appendage (LAA) closure procedures with the Watchman device. They’ve performed more than 300 minimally invasive procedures with the Watchman with excellent results.

At Valley, we offer the latest version of the device, the Watchman FLX Pro. Research shows this device has even better outcomes than the previous version. It also allows a wider range of people to reduce their stroke risks without blood thinners.

Watch: The Watchman device can help prevent stroke for certain patients who have AFib. Learn what you can expect from the procedure.

Am I a Candidate for the Watchman?

The Watchman device might be right for you if you have AFib that is not caused by heart valve disease. It could be a good option for you if you have one of the following:

• A history of major bleeding while taking blood thinners
• A career or lifestyle that increases the risk for major bleeding due to trauma
• Difficulty controlling blood clots with blood thinners

Talk to our electrophysiology team at Valley to find out if the Watchman may be right for you. If not, you may be a candidate for another minimally invasive procedure with the Amulet device.

How Does the Watchman Work?

AFib affects how your heart contracts, which leads to blood pooling in a pouch called the left atrial appendage (LAA). The LAA is where most blood clots form. If blood clots dislodge and travel through your bloodstream to the brain, it can lead to a stroke.

The Watchman implant is a tiny mesh umbrella that closes the LAA and keeps blood clots from entering the bloodstream. This reduces your risk of stroke.

Many people with AFib take blood thinners, like warfarin, to prevent stroke. With the Watchman device, you may be able to stop taking these medications.

Preparing for Your Watchman Procedure

Here’s what you can expect if you are preparing for a Watchman procedure:

• You will come to Valley for a computed tomography (CT) scan using advanced software called TruPlan. Our team uses this software to plan your procedure, which ultimately results in less time under anesthesia and fewer complications.
• We will plan where to implant the Watchman from your CT scan. We will also choose the right size of the device to use during your procedure.
• Our team will give you information about what to bring to the hospital before your procedure. We’ll also give you instructions for eating, drinking and taking your medications beforehand.

What to Expect During Your Watchman Procedure

Here’s what you can expect if you have a Watchman procedure:

• Plan to have someone drive you to and from the hospital on the day of your procedure. You’ll need someone to drive you home after the procedure.
• At the hospital, an anesthesiologist will give you general anesthesia to put you to sleep.
• Your electrophysiologist and interventional cardiologist will make a small incision in your groin to reach a vein.
• They will insert a catheter (thin tube) with the Watchman device into the vein. Using advanced image guidance, we will direct the catheter through the heart to the LAA.
• They will place the Watchman over the LAA opening and then remove the catheter.
• They will close the incision with a suture (stitch).
• The procedure takes about an hour.

Recovery After a Watchman Procedure

Here’s what you can expect after a Watchman procedure:

• Most people stay overnight in the hospital and go home the following day. Some people can go home the same day.
• Recovery time is minimal. You should be able to return to your normal activities in a few days.
• You will still need to take blood thinners for a few months after your procedure. Your doctor will discuss the best regimen for you.
