BACKGROUND
The aim of this study was to demonstrate the utility of real-time three-dimensional (3D) transesophageal echocardiography (RT3D-TEE) using a matrix array 3D transesophageal echocardiographic probe for morphologic evaluation and guidance of transcatheter closure of atrial septal defects (ASDs).
METHODS
Forty-eight consecutive patients scheduled for the intervention were included. Two-dimensional (2D) transesophageal echocardiography (2D-TEE) and RT3D-TEE were performed before and during the procedures. Measurements of maximal ASD diameter and surrounding rims obtained on RT3D-TEE were compared with those obtained on 2D-TEE.
RESULTS
In 46 patients (96%), optimal 3D images for the morphologic evaluation of ASDs were obtained. RT3D-TEE facilitated the evaluation of ASD morphology and surrounding rims and was able to provide intraprocedural information clearly. A Bland-Altman plot showed a mean maximal diameter difference of -0.12 mm between the means (95% limits of agreement, -2.2 to 2.5 mm).
CONCLUSION
RT3D-TEE is a clinically useful, complementary option to 2D-TEE for evaluation of ASD morphology and for interventional guidance.
背景
本研究旨在展示使用矩阵探头实时三维经食管超声心动图（RT3D-TEE）对房间隔缺损（ASD）进行形态评估和经导管封堵的指导作用。
方法
纳入 48 例行介入治疗的连续患者。在术前和术中进行二维经食管超声心动图（2D-TEE）和 RT3D-TEE。比较 RT3D-TEE 上测量的 ASD 最大直径和周围边缘与 2D-TEE 上测量的结果。
结果
在 46 例患者（96%）中，获得了用于 ASD 形态评估的最佳 3D 图像。RT3D-TEE 有助于评估 ASD 形态和周围边缘，并能提供清晰的术中信息。Bland-Altman 图显示，两种方法测量的 ASD 最大直径平均值之间的差异为 -0.12mm（95%一致性区间为-2.2 至 2.5mm）。
结论
RT3D-TEE 是评估 ASD 形态和介入指导的一种有用的、互补的二维经食管超声心动图选择。
