Left atrial appendage occlusion: A better alternative to anticoagulation?
نویسندگان
چکیده
Non-valvular atrial fibrillation is associated with a significantly increased risk of embolic stroke due to blood clot forming predominantly in the left atrial appendage (LAA). Preventive measures to avoid embolic events are permanent administration of anticoagulants or surgical closure of the LAA. Various clinical trials provide evidence about safety, effectiveness and therapeutic success of LAA occlusion using various cardiac occluder devices. The use of such implants for interventional closure of the LAA is likely to become a valuable alternative for stroke prevention, especially in patients with contraindication for oral anticoagulation as safety, clinical benefit and cost-effectiveness of LAA occlusion has recently been demonstrated.

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...

BACKGROUND Atrial fibrillation is associated with embolic strokes that often result in death or disability. Effective in reducing these events, anticoagulation has several limitations and has been widely underutilized. Over 90% of thrombi identified in patients with atrial fibrillation without valvular disease originate in the left atrial appendage, whose occlusion is investigated as an alterna...
متن کاملEvidence-Based Percutaneous Closure of the Left Atrial Appendage in Patients with Atrial Fibrillation
Atrial fibrillation is the most common cardiac arrhythmia, and its prevalence is increasing. Cardioembolic stroke, most of the times secondary to thrombus formation in the left atrial appendage, is its most feared and life threatening consequence. Oral anticoagulation with vitamin-K-antagonists is currently the most used prophylaxis for stroke in patients with atrial fibrillation; unfortunately...

Catheter ablation therapy for atrial fibrillation (AF) is a safe and effective treatment for patients with both paroxysmal and persistent symptomatic AF. However, given the uncertainty about recurrence after the ablation procedure and continued risk of thromboembolism, it is still recommended to treat with anticoagulation for the long-term prevention of stroke. Left atrial appendage (LAA) occlu...

Left atrial appendage (LAA) occlusion has been introduced into clinical practice as a valuable alternative to oral anticoagulation for stroke prevention in patients with non-valvular atrial fibrillation. In this case presentation we describe the first LAA occlusion in Greece using the Amplatzer Amulet device. We also briefly discuss issues related to procedural safety and multimodality imaging ...
