Abstract
Aim: Comparative analysis of the height of atherosclerotic plaques (AP) in the descending thoracic aorta (TA) according to two-dimensional (2D) and three-dimensional (3D) transesophageal echocardiography (TEE), and contrast-enhanced multislice computed tomography (MSCT).
Material and methods: The TA was examined using 2D, 3D TEE and contrast-enhanced MSCT in 34 patients (20 men and 14 women aged 68 [62; 71] years). AP heights were compared using the Bland-Altman method and the Spearman correlation analysis. This was a blinded comparative study which assessed the AP morphometry using each of the radiation modalities without knowing the results of the method being compared.
Results: 100 APs were examined in the descending TA. The mean height of all analyzed APs in the descending TA was 2.2 mm [2; 2.7] for 2D TEE, 3.1 mm [2.7; 3.55] for 3D TEE, and 3.05 mm [2.55; 3.55] for MSCT. The AP heights measured with 2D TEE was statistically significantly smaller than the heights of similar APs measured either with 3D TEE or MSCT. The mean difference (bias) was 0.88±0.34 mm between 2D and 3D TEE, and 0.83±0.41 mm between 2D TEE and MSCT. The correlation coefficients for the AP heights were r=0.87 (p<0.001) between 2D and 3D TEE and r=0.86 (p<0.001) between 2D TEE and MSCT. There were no differences in the height of similar APs between 3D TEE and MSCT.
Conclusion: The three-dimensional reconstruction of AP in the TA by TEE is more accurate for quantitative assessment of AP than a two-dimensional study.
目的：根据二维（2D）和三维（3D）经食道超声心动图（TEE）以及对比增强多层计算机断层扫描（MSCT）对降主动脉（TA）中动脉粥样硬化斑块（AP）的高度进行比较分析：使用二维、三维 TEE 和对比增强 MSCT 对 34 名患者（男性 20 人，女性 14 人，年龄 68 [62; 71] 岁）的 TA 进行了检查。使用 Bland-Altman 方法和 Spearman 相关性分析比较了 AP 高度。这是一项盲法比较研究，在不了解比较方法结果的情况下，使用每种放射模式对 AP 形态学进行评估：在降序TA中检查了100个AP。二维 TEE、三维 TEE 和 MSCT 所分析的 TA 降支动脉 AP 的平均高度分别为 2.2 毫米 [2; 2.7]、3.1 毫米 [2.7; 3.55]和 3.05 毫米 [2.55; 3.55]。二维 TEE 测量的 AP 高度在统计学上明显小于三维 TEE 或 MSCT 测量的类似 AP 高度。二维和三维 TEE 之间的平均差（偏差）为 0.88±0.34 毫米，二维 TEE 和 MSCT 之间的平均差（偏差）为 0.83±0.41 毫米。二维和三维 TEE 之间 AP 高度的相关系数为 r=0.87 (p<0.001)，二维 TEE 和 MSCT 之间的相关系数为 r=0.86 (p<0.001)。结论：结论：TEE 对 TA AP 的三维重建比二维研究更能准确定量评估 AP。
