Abbott Amulet 2 Veritas - Evaluating the safety and effectiveness of Abbott’s Amulet 2 Left Atrial Appendage occluder device
The purpose of this investigational study is to evaluate the safety and effectiveness of the Amulet 2 catheter device used in left atrial appendage occlusion procedures. This study enrolls patients with non-valvular atrial fibrillation who are at an increased risk of ischemic stroke or systemic embolism. Patients must also have an appropriate rationale to seek non-pharmacologic alternatives to oral anticoagulation.

The Amulet 2 device is designed to prevent thrombus embolization in the Left Atrial Appendage. Thrombus embolization is when a blood plot migrates from its original location in a blood vessel, which can lead to an obstruction in the circulatory system. Following the procedure, patients will receive final imaging to ensure proper placement of the device.

Abbott CATALYST - Clinical trial of atrial fibrillation patients comparing left atrial appendage occlusion therapy to non-vitamin K antagonist oral anticoagulants
The Amplatzer™Amulet™ Left Atrial Appendage (LAA) Occluder (Amulet) device is intended to be permanently implanted within the LAA. The LAA is a small pouch attached to the upper left chamber of your heart, the left atrium. In patients with non-valvular AF, clots can form on the LAA and travel to the brain, sometimes causing an ischemic stroke. The Amulet device is designed to seal off the LAA from blood flow, preventing clots from leaving the LAA and traveling to the brain.

The purpose of this randomized study is to compare the safety and effectiveness of the Amulet device compared to non-vitamin K antagonist oral anticoagulants (NOACs) for ischemic stroke reduction. Patients will be randomized 50:50 to either receive the Amulet device or receive NOAC therapy.

The Amulet device is approved in some countries outside of the US but is an investigational device in the US.
