摘　　要：【摘要】目的探讨经食管实时三维超声心动图（RT-3DTEE）在主动脉瓣狭窄患者主动脉瓣环径定量分析中的应用价值。方法65例因重度主动脉瓣狭窄行外科手术者，术中采集主动脉根部RT-3DTEE图像，运用瓣环定量软件重建主动脉瓣环，生成瓣环参数并计算基于此的瓣环径（3D-A-AAD、3D-C-AAD），并将其与外科测瓣器测值（IOAAD）进行一致性分析。结果基于三维瓣环参数的主动脉瓣环径3D-A—AAD和3D-CAAD分别为（22．4±2．1）mm、（23．4±1．9）mm。二者测值与术IO—AADF（23．4±2．2）mm]相比，差异均无统计学意义（P〈O．05），与3I）IA—AAD相比，3D-C—AAD与IO—AAD的一致性较好。结论RT3DTEE及瓣环定量分析软件不仅能重建主动脉瓣环三维形态，还可用作瓣环径定量分析工具。Objective To investigate the application of real-time three-dimensional transesophageal echocardiography （RT-3D TEE） in quantification of the aortic anuulus diameter in patients with severe aortic stenosis. Methods RT-3D TEE image of aortic root was get perioperatively in 65 patients with sever aortic valve stenosis during the surgery procedure. The aortic annulus was reconstructed in the quantitative analysis software to generate the parameters of 3 dimensional area based aortic anuulus diameter（3D-A- AAD） and 3-dimensional circumference based aortic anuulus diameter（3I）-C-AAD）. The parameters was compared with intraoperative aortic anuulus diameter（IO AAD）, which was get by the standard cylindrical valve sizer. Results The three dimensional form of the aortic annulus was related to the number of the valves. The value of 3D-C-AAD and 3D A-AAD were （22.4 ± 2.1） mm, （23.4 ± 1.9） mm, no significant difference could be detected between them and the IO-AAD （ P % 0.05）. The 3D-C-AAD had a better agreements with IO-AAD than 3D-A-AAD. Conclusions RT-3D TEE can reconstruct the three dimensional sharp of aortic anuulus,and can be used as quantitative tools to calculate its diameter.
