主动脉根部扩张的评估对包括马凡氏综合征在内的多种疾病的诊断和随访具有重要意义。然而，我们注意到，现有的图显示成人主动脉根扩张率（75%）低于儿童（90%），而预期结果相反。为了建立新的正态图，我们选择了353名正常儿童。根据美国超声心动图学会的建议，我们采用经胸超声心动图测量主动脉环、Valsalva窦、窦管交界处和升主动脉水平的主动脉根直径。所有直径与身高、体重、体表面积和年龄相关(r = 0.75 ~ 0.84, p
The evaluation of aortic root dilation is of major importance for the diagnosis and follow-up of patients with diverse diseases, including the Marfan syndrome. However, we noted that the available nomograms suggested a lower aortic root dilation rate in adults (75%) than in children (90%), when the opposite would have been expected. To establish new nomograms, we selected a population of 353 normal children. We took transthoracic echocardiographic measurements of the aortic root diameters at the level of the aortic annulus, sinuses of Valsalva, sinotubular junction, and ascending aorta according to the American Society of Echocardiography recommendations. All diameters correlated well with the height, weight, body surface area, and age (r = 0.75 to 0.84, p
