The efficacy of oral anticoagulation (OAC) for stroke prevention in patients with
nonrheumatic atrial fibrillation (AF) has clearly been established. However, a substantial …

Apparatus, systems, and methods are described for closing the base of a left atrial
appendage or other tissue structure. A tissue closure device comprises a pair of legs having …

Since the 1950s, the pathophysiologic role of the left atrial appendage (LAA) has been
known in thromboembolic disease. A variety of surgical techniques have been described to …

Objectives: We sought to determine which surgical technique of left atrial appendage (LAA)
closure is most successful by assessing them with transesophageal echocardiography …

Background: Occlusion of the left atrial appendage (LAA) is thought to reduce the risk of
thromboembolic events in patients with atrial fibrillation. Objective: To examine the LAA and …

Described here are closure devices and methods for ligating tissue, such as the left atrial
appendage, and tensioning devices and mechanism for actuating these devices. The …

Background: Closure of the fibrillating left atrial appendage (LAA) has been recommended
during valve surgery to decrease the risk of arterial embolism. However, patients undergoing …

Purpose. In more than 90% of patients with atrial fibrillation (AF), stroke is due to thrombotic
embolization from the left atrial appendage (LAA). Transcatheter occlusion with …

Introduction The effect of epicardial left atrial appendage (LAA) occlusion therapy on lipid
and glucose metabolism in atrial fibrillation (AF) patients over the long‐term follow‐up are …

Atrial fibrillation is associated with significant mortality and morbidity. The burden of
morbidity in atrial fibrillation is mostly due to stroke, one of the major causes of death and the …
