Thoracoscopic stand-alone left atrial appendectomy for thromboembolism prevention in nonvalvular atrial fibrillation.
OBJECTIVES This study sought to evaluate thoracoscopic stand-alone left atrial appendectomy for thromboembolism prevention in nonvalvular atrial fibrillation (AF). BACKGROUND Closing the left atrial appendage (LAA) is an efficacious alternative to oral anticoagulation as prevention against AF-induced thromboembolism, provided that the procedure is safe and complete. METHODS Thirty patients ...
متن کاملOutcome of stand-alone thoracoscopic epicardial left atrial posterior box isolation with bipolar radiofrequency energy for longstanding persistent atrial fibrillation
INTRODUCTION Catheter ablation of longstanding (> 1 year) persistent atrial fibrillation (AF) is associated with poor outcome. This might be due to remodelling and fibrosis formation, mainly located in the posterior left atrial (LA) wall. Therefore, we adopted a thoracoscopic epicardial box isolation of the posterior left atrium using bipolar RF energy with intraoperative testing of conduction ...
متن کاملTransesophageal echocardiographic correlates of clinical risk of thromboembolism in nonvalvular atrial fibrillation. Stroke Prevention in Atrial Fibrillation III Investigators.
OBJECTIVES This study explored the mechanisms linking clinical and precordial echocardiographic predictors to thromboembolism in atrial fibrillation (AF) by assessing transesophageal echocardiographic (TEE) correlations. BACKGROUND Clinical predictors of thromboembolism in patients with nonvalvular AF have been identified, but their mechanistic links remain unclear. TEE provides imaging of th...
متن کاملWhere We Stand on Left Atrial Appendage Closure for Stroke Prevention in Atrial Fibrillation.
PURPOSE OF REVIEW Anticoagulant therapy effectively reduces the incidence of stroke in patients with atrial fibrillation (AF) but is underutilized and frequently contraindicated. The left atrial appendage (LAA) is the primary site of thrombus formation in AF patients. Surgical and percutaneous appendage closure has been evaluated as a site-specific therapy to reduce systemic thromboembolism. ...
متن کاملNOACs vs. Warfarin for Stroke Prevention in Nonvalvular Atrial Fibrillation
Atrial fibrillation is a heart arrhythmia associated with increased risk for ischemic stroke. Vitamin K antagonists were developed to decrease a patient's clotting risk; however, these medications require therapeutic monitoring and have several drug interactions. Novel oral anticoagulants (NOACs) were developed as an alternative to vitamin K antagonists and several studies have evaluated the ab...
