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.

Left Atrial Appendage Closure versus Oral Anticoagulants in Patients with Atrial Fibrillation: Systematic Review

Clinical and Applied Thrombosis/Hemostasis
Background Oral anticoagulants (OACs) remain the standard strategy for stroke prevention in atrial fibrillation (AF) but are limited by bleeding risk, intolerance, and long-term adherence challenges.

Systematic review and meta-analysis of left atrial appendage closure's influence on early and long-term mortality and strokeCentral MessagePerspective

JTCVS Open
Objective: Left atrial appendage closure (LAAC) concomitant to heart surgery in patients with underlying atrial fibrillation (AF) has gained attention because of long-term reduction of thromboembolic complications. As of mortality benefits in the setting

Discriminating factors excluding patients from a catheter-based left atrial appendage closure and an outcome analysis of non-intervened and intervened patients

Archives of Medical Science, 2020
Introduction The catheter-based left atrial appendage closure (LAAC) has evolved as an alternative to oral anticoagulation (OAC) among non-valvular atrial fibrillation (AF) patients in whom long-term OAC is contraindicated.

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.

Early Discontinuation of Antithrombotic Treatment Following Left Atrial Appendage Closure

, 2022
20.500.12530/87855Although antithrombotic treatment is recommended after left atrial appendage closure (LAAC), some patients require discontinuation of antithrombotic treatment after LAAC without evidence on the safety of such a strategy.

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

Left atrial appendage closure for stroke prevention in atrial fibrillation: current status and perspectives. [PDF]

Atrial fibrillation (AF) is associated with an increased risk of stroke and systemic embolism, and the left atrial appendage (LAA) has been identified as a principal source of thromboembolism in these patients.
