Actual (reported)The aim of this multicenter, non-randomized observational post-approval is to compile real world outcome data on the use of an AMPLATZER LAA Occluder in subjects with non-valvular atrial fibrillation (NVAF). The AMPLATZER LAA Occluders is a transcatheter, self-expanding nitinol device intended for use in preventing thrombus embolization from the LAA.

Actual (reported)Primary Effectiveness Endpoint 1: Composite Rate of Stroke (Including Ischemic or Hemorrhagic), Systemic Embolism and Cardiovascular or Unexplained Death
The occurrence of one or more the composite of stroke (including ischemic or hemorrhagic), systemic embolism, or cardiovascular or unexplained death at 24 months from the time of enrollment
Implant through 24 months
Primary Effectiveness Endpoint 2: Composite Rate of Ischemic Stroke or Systemic Embolism
The occurrence of ischemic stroke or systemic embolism at 24 months from the time of enrollment
Implant through 24 months
Primary Safety Endpoint: Number of Subjects With All Cause Death, Ischemic Stroke, Systemic Embolism, or Device or Procedure-Related Events Requiring Open Cardiac Surgery or Major Endovascular Repair
Subjects who were treated with AMPLATZER LAA Occluders will be included.
The AMPLATZER™ LAA Occluder is intended to prevent thrombus embolization from the left atrial appendage (LAA) in patients who have nonvalvular Atrial Fibrillation (AF). It may be considered for use in patients who have a high risk of stroke and bleeding and are deemed by their physician to have an appropriate rationale to seek a non-pharmacologic alternative to long term anticoagulants.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
The subject population will include participants that are \> 18 years old and diagnosed with NVAF.
