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 Remodeling After Lariat Left Atrial Appendage Ligation.
BACKGROUND Left atrial appendage (LAA) ligation with the Lariat device is being used for stroke prevention in atrial fibrillation. Residual leaks into the LAA are commonly reported after the procedure. Little is known about the anatomic LAA remodeling after Lariat ligation. METHODS AND RESULTS In an exploratory study, we evaluated LAA 3-dimensional geometry via computed tomographic scan in 31...

متن کاملImprovement of left atrial function and left atrial reverse remodeling after surgical treatment of atrial fibrillation.
Two-dimensional speckle tracking echocardiography (2D-STE) is an emerging technology for the evaluation of left atrial (LA) function. This technique is feasible, overcomes the limitations of tissue Doppler imaging and has been demonstrated to accurately assess atrial function during the different phases of the cardiac cycle (1). Atrial structural and electrical remodeling are the hallmarks of a...
متن کاملLeft atrial spherical shape change in atrial fibrillation
Background Atrial fibrillation (AF) is associated with increase in size of the left atrium (LA). Recent studies have shown that LA shape may be an earlier and independent marker of atrial remodeling in AF. However, previous studies have been limited to qualitative assessments of shape and parameters that do not fully characterize shape. In this study, we use an entropy-driven particle-based sha...
