慢性风湿性心瓣膜病:二尖瓣狭窄

慢性风湿性心瓣膜病

图示:慢性风湿性心瓣膜病(二尖瓣狭窄)。右图可见腱索明显缩短增粗。左图显示已剖开的左心房,二尖瓣瓣膜口呈鱼口状狭窄,扩大的心房内可见附壁血栓形成(左图右侧)。

This is chronic rheumatic valvulitis involving the mitral valve. The right panel illustrates the marked shortening and thickening of the chordae tendineae. In the left panel the enlarged left atrium is opened to reveal the "fishmouth" shape of the mitral valve, which is functionally both stenotic and partially insufficient. Mural thrombi may occur in such an enlarged atrium, and one is seen at the right.
