风湿性二尖瓣病变口径超声与术后标本检测对比

Preoperative Echocardiographic Evaluation of Rheumatlc Mitral Orifice Comparedwith Postoperative Specimen Measurement

对心瓣膜替换术病人，术前了解其瓣口大小与病变情况至关重要。本文对８６例风心病人的二尖瓣口径在术前进行了超声检查，术后对切下的标本做了直接测量。两种方法测得的数据很接近，提示术前超声检查二尖瓣口径确切可靠，在临床上很有价值。

It is important to estimate the size andlesion of mitral orifice of patients with rheumaticheart disease ,who has been undergone valve replace-ment.This paper reported 86 cases,Their mitral ori-fices were evaluated by echocardiography befor op-eration and the orifices of mitral specimen were measured directly after operation. The values of mea-surement by both methods were approximate.Itshows that using of echocardiography to deteet thesize of mitral orifice preoperatively is reliable andquite valuable.
