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.
