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 کاملLeft Atrial Appendage Occlusion
Left atrial appendage (LAA) occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC), it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC) and mitral valve replacement (MVR) too. Nowadays, PTMC is perfor...
متن کاملPercutaneous left atrial appendage occlusion: New perspectives for the method.
Ischemic stroke is a common complication of atrial fibrillation (AF). Currently, oral anticoagulant drugs are the most commonly used method of stroke prevention. Left atrial appendage occlusion is thought to be the main source of thrombi in patients with AF. Percutaneous left atrial appendage is a valuable therapeutic option for selected high-risk patients with AF and contraindications for oral...
متن کاملThe role of echocardiography in percutaneous left atrial appendage occlusion.
Percutaneous device closure of the left atrial appendage (LAA) has been introduced in the last decade as a minimally invasive alternative treatment to long-term anticoagulation to reduce the risk of thrombo-embolism in patients with atrial fibrillation. Echocardiography is an essential tool at all stages of the procedure. Pre-procedural echocardiography is used to screen suitable candidates and...
متن کاملPercutaneous interventions in elderly patients with atrial fibrillation: left atrial ablation and left atrial appendage occlusion
Heart rhythm disturbances become of special importance when patients reach a senior age. Atrial fibrillation (AF) is the most prevalent arrhythmia among the old age groups, and its impact on morbidity and mortality becomes of paramount significance. In this population, AF is responsible for significant amount of thromboembolic cerebrovascular events, especially for disabling and fatal strokes. ...
