Abstract
|
|
|
|
Atrial fibrillation (AF), whether paroxysmal, persistent, or permanent, and whether symptomatic or silent, significantly increases the risk of thromboembolic ischemic stroke. Non-valvular AF increases the risk of stroke by 5 times. Thromboembolism occurring with AF is associated with a greater risk of recurrent stroke, more severe disability, and mortality. Most strokes in patients with AF result from thrombus formation in the left atrial appendage (LAA). Occlusion of the LAA by means of a device could be an alternative to oral anticoagulation, mainly in patients who cannot tolerate the latter therapy because of a high bleeding risk.
