Watchman Left Atrial Appendage Closure (LAAC) Implant
Treating atrial fibrillation (Afib)
Patients with non-valvular atrial fibrillation (AF) — an irregular heart rhythm not caused by valvular heart disease — now have an alternative to long-term, blood-thinning warfarin medication.
The Watchman Left Atrial Appendage Closure (LAAC) implant may reduce the risk of AF-related stroke for patients considered suitable for warfarin but who have reason to seek a non-drug alternative. The Watchman Implant closes off the left atrial appendage (LAA) — a small, ear-shaped sac in the muscle wall of the top left chamber of the heart — to keep harmful blood clots from the LAA from entering the bloodstream and potentially causing a stroke. By closing off the LAA, the risk of stroke may be reduced and, over time, patients may be able to stop taking warfarin.
Lowering stroke risk for AF patients
People with AF have a five times greater risk of stroke. AF can cause blood to pool and form clots in the LAA. For patients with non-valvular AF, the LAA is believed to be the source of the majority of stroke-causing blood clots.
Other benefits of the Watchman device are that it reduces non-procedure-related major bleeding, does not require open heart surgery and is a one-time implant that does not need to be replaced.
The fight against stroke
Every year, 15 million people worldwide suffer a stroke, also known as a “brain attack.” Nearly 6 million die and another 5 million are left permanently disabled.
Another important tool in fighting stroke, the Watchman device is suited for patients at increased risk of stroke and recommended for anticoagulation, suitable for warfarin and have reasons to seek a non-medication alternative to warfarin.
