Abstract :
To evaluate the diagnostic value of three-dimensional echocardiography (3-DE) in congenital heart disease such as atrial septal defect (ASD) by virtual reality (VR), ten ASDs with different size and shape were created in ten fresh explained porcine hearts. HP SONOS 5500 imaging system was employed for 3-DE reconstructed and visualized by virtual reality computing techniques. The results showed that all ASDs were successfully reconstructed. The site, geometry were well appraised in its true form. The area, maximum and minimum diameter of ASD were measured on 3D reconstruction and compared with independently measured anatomic date. Good correlation was obtained (r>0.95, P<0.01). In conclusion, VR open an exciting opportunity in the field of diagnosis of 3-DE in congenital heart disease
