Risk factors of incomplete endothelialization after left atrial appendage occlusion in patients with atrial fibrillation

Archives of Medical Science
Introduction We aimed to investigate the risk factors of incomplete device endothelialization (IDE) following left atrial appendage occlusion (LAAO) and provide a nomogram model for predicting the risks of IDE in patients with atrial fibrillation (AF ...

Comparative Endothelialization of the Watchman Plug Device and LACBES Pacifier Occluder after Left Atrial Appendage Closure

Reviews in Cardiovascular Medicine
Background: For patients with nonvalvular atrial fibrillation (NVAF), left atrial appendage closure (LAAC) is an alternative to oral anticoagulants (OACs).

Development of an in vitro test procedure for the characterization of left atrial appendage occluder devices

Current Directions in Biomedical Engineering, 2019
The implantation of an occluder in the left atrial appendage (LAA) is an emerging therapy for the treatment of patients suffering from atrial fibrillation and with a contraindication to oral anticoagulation.

Successful Percutaneous Retrieval of an Embolized Left Atrial Appendage Occluder. [PDF]

JACC Case Rep, 2022
A 75-year-old man with a previous mitral valve repair experienced embolization of a left atrial appendage occlusion device in the left atrium. The device was successfully retrieved using a double snaring technique, without the need for open surgery. This

Amplatzer Amulet Left Atrial Appendage Occluder Versus Watchman Device for Stroke Prophylaxis (Amulet IDE): A Randomized, Controlled Trial. [PDF]

Circulation, 2021
BACKGROUND Percutaneous closure of the left atrial appendage (LAA) is an alternative to chronic oral anticoagulation to reduce stroke risk in patients with nonvalvular atrial fibrillation.

Aortic Rupture and Hemorrhagic Shock After Percutaneous Retrieval of an Embolized Left Atrial Appendage Occluder. [PDF]

JACC Case Rep, 2022
Left atrial appendage (LAA) closure may be complicated by occluder embolization. Percutaneous retrieval is preferred for devices embolized to large vessels.

Acute Mitral Regurgitation Secondary to Spontaneous Left Atrial Appendage Occluder Migration. [PDF]

JACC Case Rep, 2021
A patient underwent left atrial appendage occlusion due to recurrent stroke despite new oral anticoagulant therapy. The patient later presented with severe acute mitral regurgitation secondary to occluder device migration, which was retrieved ...

Safety and Feasibility of a Novel Split Design Left Atrial Appendage Occluder: From Preclinical Investigations to First-in-Human Application. [PDF]

Cardiovasc Ther
Objective This study was designed to first evaluate the histological compatibility of the split occluder in preclinical animal models, followed by clinical validation of its procedural feasibility and occlusion effectiveness in a first‐in‐human trial cohort. Methods Eight healthy labrador retrievers were selected for this study.

Left Atrial Appendage Closure in a Patient With a Patent Foramen Ovale Septal Occluder Device

JACC: Case Reports, 2021
Left atrial appendage closure (LAAC) has evolved as a safe alternative to oral anticoagulation therapy for stroke prophylaxis. However, the presence of a patent foramen ovale (PFO) occluder device is considered a relative contraindication. Here we report

Simultaneous endovascular "edge-to-edge" clipping of the mitral valve leaflets and closure of the left atrial appendage in a high surgical risk patient

Alʹmanah Kliničeskoj Mediciny, 2022
Mitral regurgitation is one of the most common valvular heart diseases, with the gold standard of its treatment being an open surgical intervention. However, it is not always performed in patients with a high surgical risk.
