Percutaneous left atrial appendage (LAA) closure (placement of an occluder to close the appendage) is a novel procedure for stroke prevention in patients suffering from atrial fibrillation. The closure procedure planning requires accurate LAA measurements which can be obtained from computed tomography (CT) images.

Atrial fibrillation (AF) originating from the left atrium (LA) and pulmonary veins (PV) is the most prevalent cardiac electrophysiological disorder. Accurate segmentation and quantification of the LA ...
The Amulet IDE Trial is an ongoing, prospective, randomized, multi-national trial, designed to evaluate the safety and effectiveness of the AMPLATZER Amulet Left Atrial Appendage Occluder for stroke p...
Stroke is the most feared complication of atrial fibrillation. To prevent stroke, left atrial appendage exclusion has been targeted, as it is the prevalent site for formation of heart thrombi during a...
The aim of this study was to investigate the value of real time three-dimensional transesophageal echocardiography (RT3DTEE) in percutaneous closure of the left atrial appendage (LAAC). In addition, t...
The left atrial appendage (LAA) in the setting of non-valvular atrial fibrillation (NVAF) is the predominant location for intracardiac thrombus formation. An absent LAA is a very rare congenital cardi...
The Amulet™ device will be evaluated for safety and efficacy by demonstrating its performance is non-inferior to the commercially available WATCHMAN® left atrial appendage closure devic...
Atrial fibrillation is associated with increased risk of stroke mostly because of clot formation in the left atrial appendage, a small alcove in the left atrium heart chamber. Plugging thi...
Left atrial appendage closure (LAAC) is an emerging therapeutic option in non-valvular atrial fibrillation (NVAF) patients with high thromboembolic and bleeding risks. In Europe the device...

The purpose of the study is to collect data regarding ligation of the left atrial appendage at least 12 months after surgery for patients that had exclusion of the left atrial appendage as...
Ear-shaped appendage of either atrium of the heart. (Dorland, 28th ed)
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
The hemodynamic and electrophysiological action of the LEFT ATRIUM.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.
Stroke - Cerebrovascular Disease (CVA)
A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is ...
