定义

这是一种心脏疾病，当心脏泵出血液时，二尖瓣不能正常关闭。当左心室收缩时，血液通过二尖瓣从左心室异常漏入左心房。简单地说，就是血液回流到左心房。

This is a disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood from the left ventricle through the mitral valve into the left atrium when the left ventricle contracts. Simply put, there is regurgitation of blood back into the left atrium.
