Patients with atrial fibrillation are exposed to a high risk of thrombus in the left atrium that can induce cerebral vascular events or systemic embolisms. This justifies the prescription of anticoagulant therapies in patients with high risk of thromboembolic event. Percutaneous left atrial appendage closure is a new interventional strategy for patients with high risk of cardiovascular events and a counter-indication for long term treatment with anticoagulant agents. However, only few data are available on effectiveness and prognosis of patients treated by this new interventional strategy.
This national database record per-procedure and follow-up data of patients treated by left atrial appendage closure.
This database is strictly observational.
Percutaneous left atrial appendage closure is performed only for the purpose of patient care. No specific intervention is performed specifically for the database. Neither left atrial appendage closure procedure nor patient follow up are modified by patient inclusion in the database.

The aim of the study LA-EU-01 was to examine the safety and the feasibility of the LAmbreTM Left Atrial Appendage Closure System in patients with non-valvular paroxymal, persistent or perm...
The purpose of the study is to demonstrate the safety and the rate of closure of the Ultrasept Left Atrial Appendage (LAA) Closure System for the percutaneous occlusion of the left atrial ...
The objective of Left atrial appendage closure compared to standard antiplatelet therapy in patients with AF who underwent percutaneous coronary intervention (LLA-PCI) study is to evaluate...
The study cohort will consist of up to 50 patients who are candidates for Left Atrial Appendage (LAA) closure in whom oral anticoagulation is contraindicated. Subjects evaluated for left ...
Although the clinical impact of left atrial appendage (LAA) leaks still requires confirmation, the open pouch with residual flow resulting from incomplete LAA closure may promote blood sta...
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...
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 closur...
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...
We sought to provide a practical educational tool for the utilization of intracardiac echography (ICE) in the left atrium for the percutaneous closure of the left atrial appendage (LAA).
Percutaneous closure of the left atrial appendage (LAA) is a promising therapy in patients with atrial fibrillation with high risk for stroke and contraindication for oral anticoagulation (OAC). Intra...
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
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 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).
Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
