Conclusions
It is technically feasible to print 3D models of ASD from
echocardiographic data. 3D printed model of ASD based on
echocardiographic has high precision and can accurately retain the
characteristics of original data source images. This study may lay
foundation for the application of 3D printed models in procedural
planning and size selection for ASD occlusion.
