Summary According to data provided by CT, MRI and echocardiography in two-dimensional scan, the patient's heart model can be printed out by 3-dimensional print technology. We can clearly show the size. shape,number.and spatial location of ASD hole as well as surrounding tissue relations, which can be a variety of in vitrooccluder attempt. We occluded the case with ASD inferior vena type successfully by 3D print technology.
