2.
Methods: MVA of 38 patients with mitral stenosis measured by PISA method, 2 dimensional echocardiography(2DE) method, pressure half time(PHT) method and mitral blood flow continuity equality(MFCE) method were analysed with the actual mitral valve area(aMVA) as control.
目的 :探讨彩色多普勒血流显像近端等速表面积 (PISA)法测量二尖瓣狭窄瓣口面积 (MVA)的准确性。

1.
Objective To explore the accuracy and feasibility of real-time three-dimensional echocardiography biplane imaging(RT-3DE)for assessing stenotic mitral valve orifice area(MVA).
方法选择30例拟行二尖瓣置换术的风湿性二尖瓣狭窄患者,术前应用二维超声、实时三维双平面成像观察二尖瓣病变,并测量二尖瓣瓣口面积(MVA),以术后描记法测量的二尖瓣标本瓣口面积为金标准进行比较分析。

补充资料：瓣下型主动脉口狭窄
瓣下型主动脉口狭窄
subvalvular aortic stenosis
又称“主动脉瓣下型狭窄”。常见的有两种类型：①主动脉瓣下纤维隔膜型狭窄；②主动脉瓣下纤维隧道型狭窄。
