IMPACT OF LEFT ATRIAL APPENDAGE OCCLUSION ON LEFT ATRIAL FUNCTION

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...

Left atrial appendage occlusion procedures

Effects of percutaneous left atrial appendage transcatheter occlusion (PLAATO) on left atrial structure and function.

non-CSA patients may only become evident later or in larger patient cohorts. The studies on posttransplant patients (4,5) had longer follow-up times but also showed similar improvement in both CSA and non-CSA patients. The effect of CRT on CSA in our study seemed larger than in these studies, which may be explained by the fact that OSA patients were not included and new OSA was not observed in ...

Cost-Effectiveness of Left Atrial Appendage Occlusion

The idea that mechanical intervention to close the left atrial appendage (LAA) might reduce complications from atrial fibrillation (AF) is at least 70 years old. Early attempts to test this idea in humans with surgical ligation were abandoned after only a few years for 2 reasons. First, proponents soon realized that they had no way to choose the candidates believed most likely to benefit withou...
