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 Closure Under Intracardiac Echocardiographic Guidance: Feasibility and Comparison With Transesophageal Echocardiography
BACKGROUND Transcatheter left atrial appendage closure is an alternative therapy for stroke prevention in atrial fibrillation patients. These procedures are currently guided with transesophageal echocardiography and fluoroscopy in most centers. As intracardiac echocardiography (ICE) is commonly used in other catheter-based procedures, we sought to determine the safety and effectiveness of intra...
متن کاملAssessment of left atrial appendage function by transesophageal echocardiography. Implications for the development of thrombus.
BACKGROUND The predilection of the left atrial appendage (LAA) for thrombus formation has long been known. METHODS AND RESULTS We prospectively studied the two-dimensional echocardiographic and Doppler patterns of LAA function in 82 patients by transesophageal echocardiography. In the 63 patients in sinus rhythm, LAA area was measured during LAA diastole at the onset of the electrocardiograph...
متن کاملEvaluation of the Left Atrial Appendage with Real-Time Three-Dimensional Transesophageal Echocardiography: Implications For Catheter-Based Left Atrial Appendage Closure Nucifora et al: RT3DTEE Imaging of LAA
Background Precise knowledge of left atrial appendage (LAA) orifice size is crucial for correct sizing of LAA closure devices. Aim of the present study was to determine the performance of real-time three-dimensional transesophageal echocardiography (RT3DTEE) for LAA orifice size assessment, compared to twodimensional transesophageal echocardiography (2DTEE), and to investigate the impact of atr...
متن کاملEvaluation of the left atrial appendage with real-time 3-dimensional transesophageal echocardiography: implications for catheter-based left atrial appendage closure.
BACKGROUND Precise knowledge of left atrial appendage (LAA) orifice size is crucial for correct sizing of LAA closure devices. The aim of the present study was to determine the performance of real-time 3D transesophageal echocardiography (RT3DTEE) for LAA orifice size assessment, compared with 2D transesophageal echocardiography (2DTEE), and to investigate the impact of atrial fibrillation (AF)...
