LEFT ATRIAL APPENDAGE SEAL FOLLOWING PERCUTANEOUS LEFT ATRIAL APPENDAGE OCCLUSION

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...

Left 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...

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...

Percutaneous 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. ...
