Computational Fluid Dynamic Analysis of the Left Atrial Appendage to Predict Thrombosis Risk

Computational Fluid Dynamic Analysis of the Left Atrial Appendage to Predict Thrombosis Risk

During Atrial Fibrillation (AF) more than 90% of the left atrial thrombi responsible for thromboembolic events originate in the left atrial appendage (LAA), a complex small sac protruding from the left atrium (LA). Current available treatments to prevent thromboembolic events are oral anticoagulation, surgical LAA exclusion, or percutaneous LAA occlusion. However, the mechanism behind thrombus ...

a 51-year-old man was admitted to the emergency department with palpitation and atypical chest pain. he had a history of percutaneous mitral valve commissurotomy 20 years previously. he did not use any drugs. physical examination was unremarkable except for a loud s1 on auscultation. the surface electrocardiogram (ecg) showed atrial fibrillation rhythmwith rapid ventricular response and right b...

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...
