We report on a 77-year-old woman in whom percutaneous left atrial appendage (LAA) closure was performed. The patient had a left atrial myxoma resection 3 years previously, and 2 years later, she suffered a transient ischemic attack. Atrial fibrillation was detected and anticoagulation therapy was established. An episode of intracranial bleeding forced interruption of anticoagulation. Thus, percutaneous LAA closure with an Amplatzer Amulet LAA Occluder (St Jude Medical) was proposed. During the procedure, the LAA occluder migrated and became trapped in the mitral valve. Secondary massive mitral regurgitation and hemodynamic instability forced emergent cardiac surgery. Successful removal of the Amplatzer Amulet LAA Occluder was achieved.

Background: The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease-of-use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control group of LAAC employing the standard sheath.
Methods: The first n = 32 consecutively treated patients at our site using the Amulet device with the Steerable Delivery Sheath were included in this retrospective analysis.

Background: The Amulet IDE trial (AMPLATZER Amulet Left Atrial Appendage Occluder [LAAO] Investigational Device Exemption [IDE] Trial) evaluated the safety and effectiveness of the Amulet occluder (Abbott) in patients with nonvalvular atrial fibrillation. The Amulet IDE trial is the largest randomized LAAO trial, comparing the Amulet occluder with the Watchman 2.5 device (Boston Scientific).

Background: Chronic kidney disease (CKD) and end stage renal disease (ESRD) are associated with increased risk of bleeding events, including hemorrhagic stroke, and periprocedural and gastrointestinal bleeding among patients with atrial fibrillation who are on anticoagulation. Safety of percutaneous left atrial appendage occlusion (LAAO) among this patient population has been uncertain with studies showing contradictory results.
Methods: PubMed and Google Scholar databases were queried for studies comparing outcomes among patients with and without significant CKD, and with and without ESRD who underwent LAAO device implantation.

Article Synopsis
- Percutaneous interventional left atrial appendage occlusion (LAAO) is a proven method for preventing strokes in patients with atrial fibrillation (AF) and has been evaluated in a study involving 149 patients at a Berlin hospital from 2016 to 2022.
- The study compared two types of devices used in LAAO: single-occlusive plug-type (SOPT) and dual-occlusive disc-type (DODT), noting that while DODT procedures took longer, both had successful implantation with low rates of complications and no hospital deaths.
- After six months, findings indicated that SOPT had a higher rate of device-related thrombus formation compared
