Now I'm ready for an alternative
Answer a few short questions to see if you may be a candidate
As a permanent implant, WATCHMAN doesn’t come with the same bleeding risks associated with the long-term use of warfarin.3 This makes it an important option for people with a history or risk of serious bleeding on blood thinners. Newer blood thinners (also known as novel oral anticoagulant drugs) offer additional options to warfarin, but they don’t take away the long-term risk of bleeding.1
Real People and WATCHMAN
If you have atrial fibrillation and you take a blood thinner to reduce your stroke risk, you’re probably aware of the bleeding risks that come with your medication. Maybe you’ve even experienced a serious bleed and had to go the hospital.
Hear about two real patients who had serious bleeding events while taking blood thinners. In the following videos, Marjorie and Billy talk about their experiences, the effects on their families, and why their cardiologists recommended WATCHMAN. If you, too, have a history of serious bleeding, then WATCHMAN may be right for you.
You may also be a candidate for WATCHMAN if you have a lifestyle or condition that increases your risk for serious bleeding. Certain lifestyles or conditions may increase your bleeding risk by putting you at higher risk for falls or making you prone to injury in other ways. Talk to your cardiologist about your risk.
With WATCHMAN, Marjorie Feels Protected
“It was the best feeling to know that WATCHMAN would watch over me.”
Marjorie had a hemorrhagic stroke (bleeding in the brain) in 2006. It paralyzed the right side of her body. After that, she stopped taking blood thinners for a while due to her risk of bleeding. But in 2015, her doctor recommended she go back on warfarin because her stroke risk was high. Afraid of another bleeding event, Marjorie discussed her options with her doctor. See her story.

Billy Worries Less with WATCHMAN
“I can feel stronger and be here a lot longer.”
Of all the medicines Billy was on, blood thinners were the most concerning for him and his wife, Pat. Billy was having internal bleeding problems on blood thinners. After he became anemic and needed three units of blood transfused, he and his doctor made the decision to go with WATCHMAN. He and Pat believe life is good—and now even better without blood thinners. See his story.

If You're Out of Range on Warfarin
People with atrial fibrillation not caused by a heart valve problem are often prescribed warfarin, a common blood thinner, to reduce their stroke risk. If you’re taking warfarin (also known as Coumadin®), you know about the regular blood tests and food-and-drink restrictions that come with it. Some people aren’t able to get regular blood tests, or they have trouble staying within the recommend blood clotting range that the test measures. Missing your medication frequently or failing to follow dietary guidelines on warfarin can put you out of range.4
If this describes you, and you can’t take a different type of blood thinner (for example, because of cost or availability), then talk to your cardiologist about whether WATCHMAN is right for you.

Who WATCHMAN Is For
The WATCHMAN Implant may be right for people who:
- Have atrial fibrillation not caused by a heart valve problem (also known as non-valvular AFib)
- Have been recommended for blood thinning medicines by their doctor
- Can take warfarin but need an alternative
People may need an alternative to warfarin for any one of these reasons:
- Have had major bleeding while taking blood thinners
- Have a lifestyle, occupation, or condition that puts them at risk for major bleeding
- Take warfarin and have trouble staying within the recommended blood clotting range (a measurement known as INR*) or getting regular blood tests to confirm their INR, and they cannot take a different type of blood thinner
*INR, or International Normalized Ratio, is a measurement of how long it takes for your blood to clot. If you’re out of range, you may be at higher risk for stroke or at higher risk for bleeding.4
As with any medical procedure, there are risks involved with WATCHMAN. See the Important Safety Information below for a list of possible complications, and ask your cardiologist about the risks and benefits of WATCHMAN.
WATCHMAN is for people with atrial fibrillation not caused by a heart valve problem who need an alternative to warfarin. This website is intended to provide patients and caregivers with some information about the WATCHMAN Implant. It may help prepare you for talking to your doctor about your options for reducing stroke risk.
Important Safety Information
The WATCHMAN Device is a permanent implant designed to close the left atrial appendage in the heart in an effort to reduce the risk of stroke.
With all medical procedures there are risks associated with the implant procedure and the use of the device. The risks include but are not limited to accidental heart puncture, air embolism, allergic reaction, anemia, anesthesia risks, arrhythmias, AV (Arteriovenous) fistula, bleeding or throat pain from the TEE (Trans Esophageal Echo) probe, blood clot or air bubbles in the lungs or other organs, bruising at the catheter insertion site, clot formation on the WATCHMAN™ Closure Device, cranial bleed, excessive bleeding, gastrointestinal bleeding, groin puncture bleed, hypotension, infection/pneumonia, pneumothorax, pulmonary edema, pulmonary vein obstruction, renal failure, stroke, thrombosis and transient ischemic attack. In rare cases death can occur.
Be sure to talk with your doctor so that you thoroughly understand all of the risks and benefits associated with the implantation of the WATCHMAN Device.
