Left Atrial Appendage Closure Versus Direct Oral Anticoagulants in High-Risk Patients With Atrial Fibrillation.

Journal of the American College of Cardiology, 2020
BACKGROUND Percutaneous left atrial appendage closure (LAAC) is noninferior to vitamin K antagonists (VKAs) for preventing atrial fibrillation (AF)-related stroke. However, direct oral anticoagulants (DOACs) have an improved safety profile over VKAs, and

Left Atrial Appendage Closure Devices

, 2014
Atrial fibrillation (AF) increases the risk for thromboembolic stroke five-fold. The left atrial appendage (LAA) has been shown to be the main source of thrombus formation in the majority of strokes associated with AF.
