  1. Left atrial appendage occlusion (LAAO) devices are implantable cardiac devices used for stroke prevention in patients with atrial fibrillation1. They are placed in the left atrial appendage to prevent LAA thrombus from entering the systemic circulation2. LAAO can be achieved through surgical or minimally invasive procedures3. There are different devices available, including the Lariat, Watchman, and Amulet4.

    Left atrial appendage (LAA) closure devices are implantable cardiac devices which are placed in the left atrial appendage for stroke prevention in patients with atrial fibrillation who have contraindications to pharmacological anticoagulation. Depending on the device they may be inserted percutaneously or though minimally invasive or open surgery.

    LAAO devices are implanted in the heart and are intended to reduce the risk of thromboembolism from the left atrial appendage (LAA) in patients with non-valvular atrial fibrillation. The device mechanically occludes the LAA to prevent LAA thrombus from entering the systemic circulation.

    Left atrial appendage closure is a surgical or minimally invasive procedure to seal off your left atrial appendage (LAA), a small sac in the muscle wall of your left atrium (top left chamber of your heart). Removing it or closing it off can reduce your risk of stroke and eliminate the need to take blood-thinning medication.

    Occlusion of the left atrial appendage can be achieved from outside the heart (the Lariat device) or from inside the heart (endovascular) with a blood-exposed implant (the Watchman and Amulet devices). The first method is a form of ligation that eliminates perfusion of the LAA.

    What is left atrial appendage occlusion (LAAO)?
    Left atrial appendage occlusion (LAAO) is a procedure doctors can use to prevent blood clots that may lead to a stroke. It blocks off an area of the heart where up to 90% of blood clots form in people with AFib. The article explores the ins and outs of LAAO, including why it’s done, what it involves, and your outlook after the procedure.

    Should left atrial appendage occlusion be approved with the Watchman device?
    The Food and Drug Administration approved left atrial appendage occlusion with the Watchman device for patients who are at increased stroke risk and are suitable for oral anticoagulation but who have an appropriate reason to seek a nondrug alternative. These broad criteria raise the question of their interpretation in clinical practice.

    What is left atrial appendage closure?
    Left atrial appendage (LAA) closure is a procedure that blocks or closes the opening to your LAA to keep blood clots from leaving there and going into your bloodstream. This prevents strokes in people with atrial fibrillation, but without blood thinners. This appendage in one of your heart’s upper chambers doesn’t have a function.
