AI-generated Abstract

Atrial fibrillation (AF), the most common cardiac arrhythmia affecting millions globally, poses a significant stroke risk due to thrombus formation in the left atrial appendage (LAA). While anticoagulation therapy has been standard, challenges with long-term medication adherence and contraindications prompt exploration of percutaneous transcatheter LAA closure (LAAC) as an alternative for high-risk patients. The intervention shows promise as an effective option, yet demands further research considering its relative effectiveness against traditional anticoagulation, patient selection criteria, physiological impacts, and cost-effectiveness.
