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 کاملLeft atrial appendage closure.
Stroke prevention is the primary goal in atrial fibrillation (AF) given its clinical and socioeconomic impact. With AF, the prevalence of thromboembolic stroke continues to rise and there is an urgent need to develop better strategies of stroke prevention. Warfarin, although effective when used appropriately, is burdened by underutilization, narrow therapeutic windows, and life-threatening blee...
متن کاملCONGENITAL PARTIAL PERICARDIAL DEFECT WITH HERNIATION OF THE LEFT ATRIAL APPENDAGE
Congenital defects of the pericardium are considered rare. Until 1979 , the reported cases were only about 200.1 Total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. Other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 Before the last decade, t...
