A Comprehensive Guide to Using Watchman Heart Devices

Heart disease remains to be one of the leading causes of death worldwide. In an effort to curb this trend, medical professionals have been working tirelessly to come up with innovative solutions that can help prevent and treat heart disease. One such innovation is the Watchman heart device, which has been gaining popularity in recent years. In this article, we will take a closer look at what Watchman heart devices are and how they work.

What are Watchman heart devices?

Watchman is a small, implantable device that is designed to prevent stroke in individuals who have atrial fibrillation (AFib). AFib is a condition where the heart beats irregularly, which can cause blood clots to form and eventually lead to stroke. Watchman is about the size of a quarter and is inserted into the left atrial appendage (LAA) of the heart through a minimally invasive procedure.

How do Watchman heart devices work?

The LAA is a small pouch attached to the left atrium of the heart. It is where blood can pool and form clots that can lead to stroke in individuals with AFib. Watchman works by permanently sealing off the LAA, preventing blood from pooling in this area and thus reducing the risk of stroke. Once implanted, the Watchman device becomes a permanent part of the heart, and there is no need for additional medication or follow-up procedures.

Who is a good candidate for Watchman heart devices?

Watchman heart devices are generally recommended for individuals who have a history of AFib and are at risk of stroke, but are unable to take blood-thinning medication due to the risk of bleeding. This may include individuals who have had previous episodes of bleeding, those who have difficulty managing their medication, or those who prefer not to take blood thinners due to personal preference. It is important to note that not everyone with AFib may be a good candidate for Watchman, and your doctor will evaluate your individual situation to determine whether or not this option is appropriate for you.

What are the potential risks of Watchman heart devices?

Like any medical procedure, there are some potential risks associated with Watchman heart devices. The most common risks include bleeding, infection, and allergic reaction to the device. However, it is important to note that serious complications are rare, and the benefits of this device in reducing the risk of stroke may outweigh the risks in many cases.


In conclusion, Watchman heart devices represent a significant advancement in the prevention of stroke in individuals with AFib. By sealing off the LAA, Watchman reduces the risk of blood clots forming and thus helps to prevent stroke. While there are some potential risks associated with this procedure, it is generally safe and effective and may be a good option for individuals unable to take blood-thinning medication. If you have AFib, talk to your doctor about whether or not Watchman heart devices may be right for you.
