摘　　要：目的建立经食管三维超声心动图主动脉根部解剖结构定量分析方法，评价该方法的可靠性和重复性。方法采用经食管三维超声心动图获取95例成人主动脉根部解剖结构的三维容积超声，应用PhilipsQLab3DQ测量技术，建立三个相互垂直平面的坐标系。测量相关参数：主动脉根部在冠状动脉窦底水平、瓣联合上缘水平、窦管结合水平的直径和面积；冠状动脉窦深度和宽度。进行自身重复测量分析，确定研究方法的重复性。结果舒张末期，主动脉根部环径和面积在窦底水平约1．84cm和3．45cm^2；瓣缘联合上缘水平约2．97cm和7．77cm^2；窦管结合处水平约2．72cm和5．44cm^2。无冠窦、左冠窦、右冠窦宽度比较中，右冠窦宽最大，左冠窦宽最小（P〈0．05）。自身重复性测量显示良好（P〉0．50）；角度间差异性分析显示0°区域准确性高。结论采用经食管三维超声心动图三维容积图像能够建立具有一定可靠性、重复性的主动脉根部等解剖结构三维定量分析方法。Objective To establish a quantitative analysis method for the anatomic structure of aortic root by real-time three-dimensional transesophageal echocardiography, and to explore the reliability and repeatability of this method. Method.,; Ninety five adult patients underwent RT-3DTEE were included in this study.Full-volume 3D images of aortic root were acquired and analyzed offline with QLab-3DQ （iE33, Philips）. The three mutually perpendicular plane were determined. Results 1） Aortic root：At the end of diastole,the diameter and area of coronary artery sinus bottoms level was 1.84 cm and 3.45 cm2;the diameter and area of top commissural level was 2.97 cm and 7.77 cm2 ;the diameter and area of sino-tubular junction level was 2.72 cm and 5.44 cm2. 2） Aortic sinus： right coronary sinus was widest, left coronary sinus was the most stenosis（ P〈0.05）. The repeatability of each parameters was well （ P 〉0.50）. The measurement of each parameter, which analysis among different angles showed that 0° region were more accurate than others. Conclusions 3D quantitative analysis to aortic root can be established by full-volume RT-3DTEE images and has better reliability and repeatability.
