Percutaneous Left Atrial Appendage€Closure
Ma Percutaneous left atrial appendage closure technology for stroke prevention in patients with atrial fibrillation has significantly advanced in the past 2 decades. Several devices are under clinical investigation, and a few have already received Conformité Européene (CE)-mark approval and are available in many countries. The WATCHMAN device (Boston Scientific, Natick, Massachusetts) has the m...
متن کاملObliteration of the left atrial appendage for prevention of thromboembolism.
Shaped like a wizard’s hat but long considered functionally insignificant, the conical, trabeculated left atrial appendage (LAA) arises from the embryonic left atrium during the third week of gestation and extends superiorly from the anterolateral surface of the left atrium (1). This accessory chamber extends over an area of 3 to 6 cm, is more compliant than the atrium, and is actively contract...
متن کاملPercutaneous Interventions for Left Atrial Appendage Exclusion
Percutaneous left atrial appendage (LAA) exclusion is an evolving treatment to prevent embolic events in patients with nonvalvular atrial fibrillation. In the past few years multiple percutaneous devices have been developed to exclude the LAA from the body of the left atrium and thus from the systemic circulation. Twoand 3-dimensional transesophageal echocardiography (TEE) is used to assess the...
متن کاملPercutaneous Closure of the Left Atrial Appendage.
This article reviews the published evidence on stroke prevention with percutaneous closure of the left atrial appendage and provides comparative insight into the various left atrial appendage closure devices currently in development.
متن کاملA 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...
