目的：探讨实时三维经胸超声心动图（RT-3D-TTE）观察主动脉瓣病变患者瓣环几何构型的临床应用价值。方法选择主动脉瓣病变拟行主动脉瓣置换术的患者45例为病变组，年龄、性别相匹配的体检健康者40例为对照组。术前行二维经胸超声心动图（2D-TTE）和RT-3D-TTE测量主动脉瓣环径，术中应用外科测瓣器测量瓣环径。结果病变组2D-TTE、RT-3D-TTE矢状面、冠状面及手术中直径分别为（24．92±5．52）mm、（25．32±4．54）mm、（26．72±4．54）mm和（27．02±3．43）mm，2D-TTE直径小于RT-3D-TTE直径及手术中直径（P＜0．05）。2D-TTE、RT-3D-TTE直径与手术中直径之间均具有相关性，RT-3D-TTE冠状面直径相关性最佳（r为0．842）。两组冠状面直径大于矢状面直径（P＜0．05），病变组RT-3D-TTE冠状面直径大于对照组（P＜0．05）。结论主动脉瓣环近似椭圆形，冠状面直径较大。RT-3D-TTE测量的主动脉冠状面直径与手术中直径相关性最佳，对主动脉瓣置换术瓣膜大小的选择有参考意义。

Objective To investigate clinic application value on annulus geometry in patients with aortic valve disease using real-time three-dimensional transthoracic echocardiography (RT-3D-TTE). Methods Forty-five patients scheduled to have aortic valve operation were enrolled as observation group received 2D-TTE and RT-3D-TTE before operation. Forty healthy adults matching with age and gender were enrolled as control group received 2D-TTE and RT-3D-TTE. Valve annulus diameters in observation group were measured by cylindrical sizers during operation. Results The diameter of aortic annulus measured by 2D-TTE was (24.92 ±5.52)mm. The annulus diameters of sagittal view and coronal view which measured by RT-3D-TTE were (25.32±4.54)mm and (26.72±5.22)mm, respectively. The diameter of aortic annulus measured by cylindrical sizers during operation was (27.02±3.43)mm. The diameter of aortic annulus measured by 2D-TTE was smaller than by RT-3D-TTE and cylindrical sizers during operation ( P <0 . 05 ) . 2D -TTE、RT -3D -TTE and operational assessment of aortic annulus had good correlation. The diameters of coronal view measured by RT-3D-TTE had the largest correlation with operational assessment (r=0.842).The annulus diameters of coronal view were larger than those of sagittal view in the two groups( P<0.05). The diameters of coronal view in observation group were larger than control group (P<0.05). Conclusion The shape of aortic annulus was near elliptical. The diameter of coronal view was larger than sagittal view. The diameter of coronal view measured by RT-3D-TTE had the largest correlation with operational assessment, which might be great help for selecting valve needed by aortic valve replacement.
