Abstract:
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.Methods 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 cm 2 ;the diameter and area of sino-tubular junction level was 2.72 cm and 5.44 cm 2 .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.
