WATCHMANTM Implant Surgery
Request a Cardiologist Referral
The WATCHMAN device offers a safe, minimally invasive solution for individuals with atrial fibrillation (AFib) who are looking to reduce their risk of stroke without relying on long-term blood thinners. At Baptist Health System, we understand the concerns that come with managing AFib, and we are proud to offer this treatment to help protect your health. By closing off the left atrial appendage, the WATCHMAN implant can help reduce stroke risk, providing an alternative for those who cannot take blood thinners long-term.
What Is the WATCHMAN Procedure?
Atrial fibrillation, or AFib, is a heart condition where the upper chambers of the heart (the atria) beat irregularly. This can cause blood to pool in the heart, increasing the risk of blood clots. If these clots travel to the brain, they can block blood flow, leading to a stroke. Strokes may result in loss of vision, speech, mobility, and in some cases, can be fatal.
Around 15-20% of people who experience strokes have AFib. To reduce the risk of stroke, patients with AFib are often prescribed blood thinners, like anticoagulants or antiplatelet medications. However, long-term use of these drugs can raise the risk of excessive bleeding. For patients with nonvalvular AFib, a type of AFib not related to heart valve problems, the WATCHMAN device offers a minimally invasive alternative to blood thinners.
How Does WATCHMAN Work?
Although blood thinners help lower the risk of stroke in people with AFib, they can also interfere with clotting when it's needed, such as when the body is trying to heal a wound or damaged blood vessels. Clotting helps prevent infections by protecting injured areas.
The WATCHMAN for atrial fibrillation is an FDA-approved implant, roughly the size of a quarter, made from lightweight, compact materials. Its purpose is to permanently seal off the left atrial appendage, helping reduce stroke risk and allowing patients to stop long-term use of blood thinner use.
Who Is a Candidate for the WATCHMAN Procedure?
The WATCHMAN implant for AFib is recommended for people who have nonvalvular atrial fibrillation and who are potential candidates for blood thinners. Although taking blood thinning medications is the standard treatment for nonvalvular atrial fibrillation, some people cannot take them. According to the WATCHMAN website, as a permanent procedure, the implant does not have the same bleeding risks associated with the long-term use of blood thinners.
Like any surgery, the WATCHMAN procedure comes with risks. Do not make changes to your AFib treatment plan unless instructed by your cardiologist.
The WATCHMAN Implant Procedure
During the WATCHMAN AFib procedure, doctors make a small incision in the upper leg and insert a thin tube to guide the device into the left atrial appendage. The procedure, done under general anesthesia, usually takes less than an hour. Most patients spend one night in the hospital and are discharged the following day.
After the procedure, patients may need to continue taking blood thinners for up to 45 days, or until the left atrial appendage is fully sealed off by the device. As the body heals, heart tissue forms a protective layer over the WATCHMAN implant, reducing the risk of blood clots. To ensure it's safe to stop blood thinners, doctors will use imaging to monitor the heart’s healing progress. In some cases, patients may need to stay on blood thinners for six months or longer.
Does WATCHMAN Stop Atrial Fibrillation?
The WATCHMAN procedure doesn't cure AFib; its main goal is to lower the risk of stroke caused by the condition. While AFib currently has no cure, there are treatments available that can help manage symptoms and reduce the risk of complications.
