| 摘 要： | 目的：探讨实时三维超声xPlane成像（RT 3DxPlane）评价风湿性二尖瓣狭窄瓣口面积的准确性。方法：36例拟行二尖瓣置换的风湿性二尖瓣狭窄患者，术前应用二维面积法和RT 3DxPlane法测量狭窄二尖瓣口面积（MVA），分别获得 MVA2D和MVAxPlane。术后对二尖瓣标本采用照相法测量瓣口面积（MVAOP），与上述两种方法测值进行比较。结果：MVAOP与MVAxplane之间差异无统计学意义（P>0.05），但与MVA2D间差异有统计学意义（P<0.05）。MVA2D，MVAxPlane与MVAOP相关系数分别为0.95和0.97 （P<0.05）。MVA2D，MVAxPlane与MVAOP间均有良好的一致性。结论：实时三维xPlane成像法能够简便、快速、准确测量二尖瓣口狭窄面积。

| Abstract: | Objective: To determine the feasibility and accuracy of real time three dimensional xPlane imaging(RT3DxPlane) for the evaluation of mitral valve area(MVA) in patients with rheumatic mitral stenosis.Methods: MVA were measured using two dimensional echocardiography(MVA2D) and RT 3DxPlane(MVAxPlane) in 36 patients.The stenotic mitral specimens were acquired in mitral valve replacement surgery,and MVAOP as the golden standard of MVA was calculated with photoshop and Matlab software.Results: There was no signif... |
