Abstract:
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-AAAD) and 3-dimensional circumference based aortic anuulus diameter(3D-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.
