For the millions in America with atrial fibrillation, a type of abnormal heartbeat, treatment has traditionally included lifelong medication therapy to reduce stroke risk. However, Georgia Heart Institute is pleased to offer innovative alternatives to reduce the risk of stroke. See below to learn more about atrial fibrillation and the left atrial appendage closure (LAAC) implantable devices offered through Georgia Heart Institute.
Atrial fibrillation typically causes a fast and irregular heartbeat and significantly increases the risk of stroke by promoting blood clots that form predominantly in an area of the left atrium called the left atrial appendage. Patients commonly develop symptoms of heart fluttering or palpitations, fatigue, shortness of breath, chest discomfort, dizziness, or increased leg or ankle swelling.
Because atrial fibrillation causes abnormal, weaker contractions of the heart, blood pools in the heart and can form blood clots. If a clot leaves the heart and travels to the brain, it can block the flow of blood through the arteries, causing a stroke. As a result, those with atrial fibrillation are five times more likely than the general population to suffer a stroke.
Most patients with non-valvular atrial fibrillation are potential candidates for left atrial appendage closure devices. This includes patients who are recommended to have anticoagulation therapy but aren’t suitable candidates for various reasons such as:
- a history of serious bleeding,
- frequent falling with injuries
- intolerable side effects from the medications.
A thorough evaluation by a cardiologist or electrophysiologist is essential to determine the most suitable device option based on individual health conditions and risk factors.
WATCHMAN
The WATCHMAN is an implantable device that is inserted into the left atrial appendage through catheters that are inserted into a vein in the leg, The device plugs off and seals the left atrial appendage from the left atrium to prevent future clot formation. The innovative aspect of this non-surgical procedure is the way that stroke risk is reduced by closing off the left atrial appendage, which eliminates the need for long-term anticoagulant therapy.
Amulet
The Amulet left Atrial Appendage Occluder is an advanced medical device designed to reduce the risk of stroke in patients with atrial fibrillation by closing off the left atrial appendage, a small pouch in the heart where blood clots often form. This minimally invasive device is implanted via catheterization, providing a less invasive alternative to long-term anticoagulant therapy. By sealing the left atrial appendage, the Amulet device helps prevent the formation of blood clots, thereby lowering the risk of stroke and potentially improving patient outcomes and quality of life for those with atrial fibrillation.
