WATCHMAN Reduces the Risk of Stroke from Non‑valvular AFib

There’s an alternative to blood thinners for people who need one. It’s called WATCHMAN. The only FDA-approved implant proven to reduce stroke risk in people with atrial fibrillation not caused by a heart valve problem (also referred to as non-valvular AFib). Watch the video to learn more and talk to your cardiologist about WATCHMAN.

Beyond Blood Thinners

Over a 1/3 of people with AFib feel trapped between the fear of having a stroke and fear of the risks associated with blood thinners. In fact, more than 4 in 5 people with AFib taking a blood thinner (83%) say they would be willing to try a different treatment to help reduce their risk of stroke.1

WATCHMAN effectively reduces the risk of stroke—without the risk of bleeding that can come with the long-term use of blood thinners.2,3
