三维超声心动图定量评价二尖瓣反流患者瓣膜结构功能和反流程度研究进展

二尖瓣反流（MR）是最常见的瓣膜病变之一。利用超声心动图能够对瓣膜结构功能和反流程度进行评估，为临床诊疗提供依据。三维超声心动图定量技术较常规超声心动图可更好地描述瓣膜结构功能、更准确地评估反流程度，对临床治疗决策和疾病风险分层均具有重要意义。本文就三维超声心动图定量评估MR患者瓣膜结构和反流程度的研究进展做一综述。

Progresses of three-dimensional echocardiography quantitative evaluation in valve structure and function and degree of regurgitation for patients with mitral regurgitation

Mitral regurgitation (MR) is one of the most common valve lesions. Echocardiography can effectively evaluate the valve structure and reflux, and provide a basis for clinical diagnosis and treatment. Compared with conventional echocardiography, the quantitative technique of three-dimensional echocardiography can better describe the valve structure and function, and more accurately assess the degree of reflux, which is of great significance for clinical treatment, decisions and disease risk stratification. The research progresses of quantitative evaluation of valve structure and reflux in patients with mitral regurgitation by three-dimensional echocardiography were reviewed in this article.
