Impact of Pulsed‐Field Ablation on the Left Atrial Appendage Diameter—Insights From Intra‐Procedural Echocardiography

Journal of Cardiovascular Electrophysiology, Volume 36, Issue 12, Page 3149-3155, December 2025.
Impact of pulsed‐field ablation on the left atrial appendage diameter ABSTRACT Introduction Concomitant pulmonary vein isolation (PVI) and left atrial appendage (LAA) occlusion (LAAO) have become frequently used therapies. Pulsed‐field ablation (PFA), will likely be used for combined PVI plus LAAO procedures.

Comparing Effectiveness and Safety of Left Atrial Appendage Closure Devices: A Network Meta‐Analysis of Randomized Controlled Trials

Clinical Cardiology, Volume 48, Issue 11, November 2025.
In this network meta‐analysis of randomized controlled trials comparing Watchman, Amplatzer Amulet, and/or anticoagulation, we found evidence that Amulet was associated with significantly greater risk of pericardial effusion than Watchman (RR = 2.12). Safety and effectiveness of these devices were otherwise comparatively similar.

Impact of Immunosuppressive Drugs on Patients With Percutaneous Left Atrial Appendage Occlusion

Journal of Cardiovascular Electrophysiology, Volume 36, Issue 11, Page 2979-2989, November 2025.
ABSTRACT Introduction Percutaneous left atrial appendage closure (LAAC) reduces the risk of thromboembolic stroke in patients with non‐valvular atrial fibrillation who cannot tolerate long‐term oral anticoagulation. However, outcomes after LAAC in patients requiring chronic immunosuppressive therapy (IMS) remain unknown. This study aimed to investigate

Real-world experience utilizing the nuvision 4D intracardiac echocardiography catheter for left atrial appendage closure

Scientific Reports
Transesophageal echocardiography (TEE) has been the preferred imaging modality to help guide left atrial appendage closure. Newer technologies such as the Nuvision 4D Intracardiac echocardiography (ICE) catheter allow for real-time 3D imaging of cardiac ...

Percutaneous Left Atrial Appendage Closure in Patients With Cardioembolic Breakthrough Stroke: An International Observational Study

European Journal of Neurology, Volume 32, Issue 9, September 2025.
Main Results of the Study. ABSTRACT Background Patients with non‐valvular atrial fibrillation (AF) who experience an ischemic stroke despite oral anticoagulation (OAC) are at particularly high risk of recurrence, with a reported annualized ischemic stroke rate of 5.3%–8.9%. The optimal strategy for secondary prevention in these patients remains unknown.

ST ELEVATIONS DURING LEFT ATRIAL APPENDAGE OCCLUSION (LAAO) SECONDARY TO WATCHMAN DEVICE COMPRESSION OF THE LEFT CIRCUMFLEX (LCX) ARTERY: A CASE REPORT

American Journal of Preventive Cardiology
Therapeutic Area: Ischemic Stroke Case Presentation: A 67-year-old male, with paroxysmal atrial fibrillation (AF), CHADS-VASc 3, and HAS-BLED 3, was admitted for elective WATCHMAN left atrial appendage occlusion (LAAO).

Intracardiac echocardiography versus transesophageal echocardiography guidance on left atrial appendage occlusion in patients with atrial fibrillation: A systematic review and meta‐analysis

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
ICE is a viable alternative to TEE for guiding LAAO in atrial fibrillationpatients unable to tolerate anti‐coagulants, especially those unfit for general anesthesia. It offers high procedural success, reduced device use, and comparable safety, though with a slightly increased risk of pericardial effusion.

Steerable Delivery Sheath for Optimized LAA Closure: First Experience and Procedural Outcomes

Catheterization and Cardiovascular Interventions, Volume 106, Issue 1, Page 73-79, July 1, 2025.
ABSTRACT 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 ...

Late migration of a left atrial appendage closure device to the bifurcation of common iliac arteries: a case report and novel percutaneous retrieval technique

BMC Cardiovascular Disorders
Transcatheter left atrial appendage closure (LAAC) serves as a mechanical stroke prevention strategy for patients with non-valvular atrial fibrillation (NVAF) who are unsuitable for long-term oral anticoagulation.

Anatomical description of malformations of the neck of the left atrial appendage

Clinical Anatomy, Volume 38, Issue 4, Page 471-479, May 2025.
Abstract The recently‐described left atrial appendage (LAA) neck is a truncated cone‐shaped structure that connects the LAA orifice to its lobe. It shows malformations in some cases, but their exact description and clinical significance are unknown. Therefore, the aim of this study was to provide a detailed anatomical and morphometric analysis of LAA ...
