Left Atrial Appendage Occlusion With The Amplatzer Amulet Device: The Southeast Asia Observational Study

The Amplatzer Amulet LAAO is a transcatheter, self-expanding device intended for use in preventing thrombus embolization from the left atrial appendage. The device is constucted from a nitinol mesh and consists of a lobe and a disc connected by a central waist. Polyester patches are sewn into both the lobe and disc to facilitate occlusion. The lobe has stabilizing wires to improve device placement and retention. The device has threaded screw attachments at each end for connection to the delivery and loading cables. The device has radiopaque markers at each end and at the stabilizing wires that permit visibility during fluoroscopy.
