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.

Presence of patent foramen ovale does not increase cerebrovascular event rates in patients with atrial fibrillation following left atrial appendage closure

Heliyon
Objective: Both atrial fibrillation (AF) and patent foramen ovale (PFO) has been associated with occurrences of ischemic stroke. The aim of this study was to investigate whether patients with concomitant AF and PFO were at an increased risk of stroke ...

Novel Sulfur‐Containing Polyurethanes using 5‐(Chloromethyl)Furfural as a Renewable Building Block

ChemSusChem, Volume 18, Issue 18, September 23, 2025.
A novel methodology is presented for synthesizing biomass‐derived diols using 5‐(chloromethyl)furfural, thiols, and mild reaction conditions. These innovative diols are subsequently utilized in the production of new polyurethanes via polyaddition with both commercially available and biomass‐derived diisocyanates.

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.

Stroke prevention in atrial fibrillation: A narrative review of current evidence and emerging strategies

European Journal of Clinical Investigation, Volume 55, Issue 9, September 2025.
Effective stroke prevention in AF requires a comprehensive holistic approach incorporating appropriate risk stratification, guideline‐adherent anticoagulation and management of underlying cardiovascular conditions and other comorbidities. The ABC pathway, supported by characterisation using the 4S‐AF framework, provides a structured approach to ...

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.

Left Atrial Appendage Closure in Patients Refusing Oral Anticoagulation: The LAAC‐REFUSAL Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The benefit of left atrial appendage closure (LAAC) in patients refusing oral anticoagulation (OAC) despite medical recommendations is unknown. We aim to assess the efficacy and the safety of LAAC in patients refusing OAC.

A Case of Idiopathic Chest Pain Following Watchman Device Placement

Clinical Case Reports, Volume 13, Issue 8, August 2025.
ABSTRACT Chest pain following left atrial appendage closure (LAAC) with the Watchman device is rare but can occur due to complications such as pericarditis or myocardial infarction. We present the case of a 59‐year‐old male with atrial fibrillation who developed sharp, left‐sided chest pain exacerbated by inspiration after undergoing Watchman device ...
