2D超声对风湿性二尖瓣钙化诊断的价值

本文对100例风湿性二尖瓣钙化、纤维化进行了术前的超声检查和术后切除的瓣膜标本的大体和X线拍片检查,提出了二尖瓣钙化、纤维化程度的超声分类标准。三种方法表明二尖瓣钙化、纤维化的检出率分别为57～60％、40～43％。超声、X线拍片二种方法对照,钙化符合率Ⅱ、Ⅲ度为100％,点状、Ⅰ度为92.8％;纤维化符合率Ⅰ、Ⅱ度为100％。Ⅲ度为85％。钙化、纤维化分布均以交界为多见,其程度与瓣口狭窄有一定的关系。本文进一步证明了超声诊断二类瓣钙化、纤维化的敏感性和准确性,并可作为临床选择手术的依据之一。

The estimation of rheumatic valvular calcification by two-dimensional echocardiography

In this paper 100 cases with rheumatic mitral valvular calcification (MVCa) or/and fibrosis (MVFi) were examined by echoeardiography before operation. The valvular specimens were examined by naked eye and X--ray after operation. We provide the ultrasonic classifying standard of judging the degrce of MVCa and MVFi. Three methods appcared the detectable rate of MVCa and NVFi were 57～60% and 40～43% respectively. The results of contrasting ultrasonic diagnosis with roentgen diagnosis showed: The coincidental rate of calcification degree 2 or 3 was 100%, punctare or degree I was 92.8 %. The coincidental rate of fibrosis degree 1 or 2 was 100%, degree 3 was 85%. The distribution of MVCa or MVFi was dominant in valvular junction. The extent of MVCa or MVFi was correlative with mitral valvular stenosis. This study further comfirms the sensitivity and reliability of diagnosing valvular MVCa and MVFi by echocardiography. This method can be regarded as one of the basis of choosing operative way in clinical practice.
