Transcatheter closure of the left atrial appendage: Initial experience with the amplatzer cardiac plug device.

Summary of "Transcatheter closure of the left atrial appendage: Initial experience with the amplatzer cardiac plug device."

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.

Medical and Biotech [MESH] Definitions

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).
