mitral regurgitation

基本解释

Objective To investigate the mechanism of functional mitral regurgitation (FMR).
目的探討功能性二尖瓣返流的機制。
Objective: To explore the roles of color Doppler vena contracta in the evaluation of mitral regurgitation grading.
目的：探討彩色多普勒過返流口寬度在估測二尖瓣返流程度中的作用。
The aim of study is to detect the influence of left ventricle and mitral apparatus remodeling on mitral regurgitation in different conditions by echocardiography, and investigate the mechanism of IMR.
本研究擬通過超聲心動圖檢測不同情況下左室和二尖瓣裝置的重搆及其對反流的影響，探討缺血性二尖瓣返流的機制，共分四部分。

The panel met to evaluate use of the novel device in patients with significant symptomatic mitral regurgitation (MR) who have been determined by a cardiac surgeon to be too high risk for open mitral valve surgery and in whom existing co-morbidities would not preclude the expected benefit from correction of the MR.
