Percutaneous left atrial appendage (LAA) closure might reduce the cardioembolic risk in those patients with nonvalvular atrial fibrillation who are not candidates for warfarin therapy. This report presents the case of two patients with atrial fibrillation who had contraindications for warfarin therapy due to bleeding complications and a high cardioembolic risk (CHADS2 >/=2) who underwent successful LAA closure with a new device, the Amplatzer Cardiac Plug. The characteristics of the device and the main technical aspects of the procedure, as well as the potential advantages of this device for LAA closure, are discussed. (c) 2010 Wiley-Liss, Inc.

Modifications in left atrial (LA) flow velocities after left atrial appendage (LAA) exclusion have been shown in animal and ex vivo models. In a substudy of the PROTECT AF, an objective improvement in...
There is limited data with WATCHMAN for left atrial appendage (LAA) closure in patients with non-valvular atrial fibrillation (AF) and contraindications to anticoagulation. The purpose of this study w...
To compare indications and clinical outcomes of two contemporary left atrial appendage (LAA) percutaneous closure systems in a "real-world" population.
Whereas the left atrial appendage plays a rather minor role under physiological circumstances, it gains an importance in patients with atrial fibrillation. Compelling evidence has revealed that the l...
In patients with atrial fibrillation, closure of the left atrial appendage (LAA) is recommended to prevent thromboembolic events, however, conventional exclusion or excision techniques have potential ...
This study will evaluate thrombogenicity in patients undergoing left atrial appendage closure using the WATCHMAN device. Parameters of thrombosis and platelet function, as well as other bi...
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 ...
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 ...
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...
Ear-shaped appendage of either atrium of the heart. (Dorland, 28th ed)
The hemodynamic and electrophysiological action of the LEFT ATRIUM.
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.
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
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).
