Study of Safety and Efficacy of a Left Atrial Appendage Occulder

2016-10-19 02:38:21 | BioPortfolio

Summary

This study mainly evaluated the feasibility and safety of a kind of Left Atrial Appendage Occluders which is to prevent ischemic stroke caused by nonvalvular atrial fibrillation (AF)

Description

Atrial fibrillation (AF) is a common arrhythmia, its incidence increases with age. Thrombosis shed off caused by AF is one of the major causes of stroke. Most patients with AF suffer ischemic stroke that the thrombosis was from the left atrial appendage(LAA). The majority of patients with atrial fibrillation, the blood clots come from the left atrial appendage, so close the left atrial appendage can reduce cycle thromboembolism of the patients with AF. Now patients have cardiac surgery and risk at left atrium related thromboembolism, the surgery has been conventional perform the left atrial appendage closed surgery.

However, surgical left atrial appendage ligation is difficult to be completely closed to the left atrial appendage,internal medicine intervention methods of surgical closure the left atrial appendage is relatively simple, minimally invasive, high success rate and is expected to be widely used.

Several versions of LAA occlusion devices have been developed.LAA occluder of Shanghai Push Medical Device Technology CO.td, consists of a fixed ball and a cover; The fixed ball composed of multiple umbrella and covered the ePTFE membrane.This study mainly evaluated the feasibility and safety of the new Left Atrial Appendage Occluder! Through the femoral vein puncture; insert inter atrial septum puncture device; puncture a small hole in the atrial septal, delivery sheath is inserted in the femoral vein puncture site and across the atrial septal reach the left atrial appendage, establishment of the channel. Through the built-channel sent the LAA occluder to the left atrial appendage by the delivery cable; The LAA occlude will be fixed in the left atrial appendage, close the entrance of the left atrial appendage meanwhile and block blood flow; then eliminate the risk of blood clots due to atrial fibrillation, prevention stroke.

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).
