The purpose of this study was to assess wall motion velocities of the abdominal aorta using tissue Doppler imaging (TDI) in 12 patients with Marfan syndrome and 30 age-matched normal controls. The patients with Marfan syndrome displayed an increased aortic stiffness index in the abdominal aorta, and significant relationships were observed between wall motion velocities of the abdominal aorta and the aortic stiffness index. Thus, TDI analyzes aortic expansion and contraction velocities and allows the identification of abdominal aortic stiffness in patients with Marfan syndrome.
本研究的目的是使用组织多普勒成像（TDI）评估12例马凡综合征患者和30例年龄匹配的正常对照者的腹主动脉壁运动速度。马凡综合征患者腹主动脉的主动脉僵硬度指数升高，并且观察到腹主动脉壁运动速度与主动脉僵硬度指数之间存在显著相关性。因此，TDI可分析主动脉的扩张和收缩速度，并有助于识别马凡综合征患者的腹主动脉僵硬情况。
