A Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملComplex left atrial appendage morphology and left atrial appendage thrombus formation in patients with atrial fibrillation.
BACKGROUND In patients with atrial fibrillation (AF), most thrombus forms in the left atrial appendage (LAA). However, the relation of LAA morphology with LAA thrombus is unknown. METHODS AND RESULTS We prospectively enrolled 633 consecutive patients who were candidates for catheter ablation for symptomatic drug-resistant AF. Transesophageal echocardiography (TEE) was performed to assess LAA ...
متن کاملLeft Atrial Appendage: Extending the Search for New Sources of Atrial Fibrillation Triggers.
The discovery of the role of the pulmonary veins (PVs) in atrial fibrillation (AF) has facilitated us to perform an anatomy-based ablation, “PV isolation”. Although several new mapping technologies have been developed, activation mapping during ongoing AF is still challenging. To improve the efficacy of AF ablation, therefore, we attempted to find the second “hot spot”. The superior vena cava, ...
متن کاملLeft Atrial Appendage Exclusion for Stroke Prevention in Atrial Fibrillation
The public health burden of atrial fibrillation (AF) and associated thromboembolic stroke continues to grow at alarming rates. AF leads to a fivefold increase in the risk of stroke. Therefore, stroke prevention remains the most critical aspect of AF management. Current standard of care focuses on oral systemic anticoagulation, most commonly with warfarin and now with newer agents such as dabiga...
متن کاملThe WATCHMAN left atrial appendage closure device for atrial fibrillation.
Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting an estimated 6 million people in the United States (1). Since AF affects primarily elderly people, its prevalence increases parallel with age. As such, it is expected that 15.9 million Americans will be affected by the year 2050 (2). Ischemic stroke occurs in 5% of non-anticoagulated AF patients each year. Current treatme...
