Abstract

Background and aim

Aortic root (AoR) dilatation is a condition that requires monitoring of its growth through serial imaging studies in order to determine appropriate treatment. Systematic differences in AoR measurements have been reported between transthoracic echocardiography (TTE) and cross-sectional imaging techniques. The aim of this study was to determine which AoR measurement-performed using cardiac computed tomography angiography (CCTA) in patients with tricuspid aortic valves-shows the best correlation with the standard measurement obtained by TTE.

Material and methods

A retrospective analysis was conducted on 110 patients who underwent both CCTA and TTE within a six-month interval at our institution, including an equal number of patients with and without AoR dilatation. On the transverse plane of the AoR in CCTA, the following measurements were taken: cusp-to-commissure, cusp-to-cusp, area, area-derived diameter (ADD) and anteroposterior diameter (APD). CCTA measurements showed excellent correlation with TTE (p < .001), with the highest degree of agreement observed for ADD and APD (both p < .001).

Results

APD measurements did not differ significantly from those obtained by TTE in any group (overall p = .451; non-dilated AoR p = .427; dilated AoR p = .091), in contrast to the other measurements, including ADD.

Conclusion

The APD measurement obtained by CCTA proved to be equivalent to that obtained by TTE, easy to perform and highly reproducible. Future research may establish APD as the reference measurement for comparing results between both techniques.

用ATCC测量主动脉根：与经胸超声心动图的一致性

背景和目的牙根（AoR）扩张是一种需要通过一系列影像学研究监测其生长情况以确定适当治疗的疾病。经胸超声心动图（TTE）和横断面成像技术在AoR测量上有系统的差异。本研究的目的是确定在三尖瓣主动脉瓣患者中使用心脏计算机断层血管造影（CCTA）进行的AoR测量与TTE获得的标准测量结果具有最佳相关性。材料和方法回顾性分析了我院在6个月内接受CCTA和TTE治疗的110例患者，其中包括相同数量的有和没有AoR扩张的患者。在CCTA的AoR横切面上，测量以下数据：尖对尖、尖对尖、面积、面积衍生直径（ADD）和前后直径（APD）。CCTA测量结果显示与TTE有极好的相关性（p < .001），其中ADD和APD的相关性最高（p < .001）。结果各组APD测量值与TTE测量值无显著差异（总体p = 0.451；未扩张AoR p = 0.427；扩张AoR p = 0.091），与其他测量值（包括add）比较，差异均无统计学意义。结论CCTA测量APD与TTE测量值相当，操作简便，重复性高。未来的研究可以建立APD作为比较两种技术结果的参考测量。
