摘要
目的：评价立体超声心动图技术（Stereo Echo）诊断继发孔型房间隔缺损的临床应用价值。方法：应用Stereo Echo技术观察12例继发孔型房间隔缺损患者的缺损形态、大小、空间位置及毗邻关系等。结果：12例患者均取得满意的实时三维超声图像。Stereo Echo模式能准确测定房间隔缺损的大小，普通三维显示模式和Stereo Echo测量的房间隔缺损直径未见明显差异[（2.89±0.73）cm vs （2.85±0.72）cm，P>0.05]，二者间测值显著相关（r＝0.96，P<0.05）。Stereo Echo上缺损断面显示清晰、立体，与毗邻结构的前后层次关系明显。普通显示模式和Stereo Echo对冠状静脉窦的显示率分别为93.3%（10/12），100%（12/12）；对上、下腔静脉的平均成像时间分别为（11.03±3.76）s vs （10.33±3.59）s（P>0.05）。结论：Stereo Echo能有效改善三维超声图像的清晰度，准确测量房间隔缺损大小，快速识别房间隔周邻结构，为外科微创或介入房间隔封堵术的安全、高效的进行具有重要潜在应用价值。
Abstract
Objective: To evaluate the clinical value of stereoscopic echocardiography(Stereo Echo) in the diagnosis of secundum atrial septal defect(ASD). Methods: Twelve patients with secundum ASD were examined using real time 3D echocardiography. Stereo Echo was generated with a high-performance volume renderer with stereoscopic glasses. Stereo Echo was compared with 3D echocardiography with standard display for assessment of the shape, size, and the surrounding tissues of ASD. Results: Stereo Echo could accurately measure the diameter of ASD, there was no significant difference between stereoscopic vision display and standard display[(2.89±0.73)cm vs (2.85±0.72)cm, P>0.05]. The appearance rate of coronary sinus for Stereo Echo is higher compared with the standard display(100% vs 93.3%). The mean time of the IVC, SVC for Stereo Echo was slightly shorter than those of the standard display[(10.33±3.59)s vs (11.03±3.76)s, P>0.05]. Conclusions: Stereo Echo improved the visualization of 3D echocardiography ultrasound images, potentially improving the safety of the surgical interventions.
