Survey results for eight typical cases between experienced surgeons and sonographers and students. The correctness of diagnosis results with CT and echocardiography, with blood pool 3D prints and echocardiography, and with myocardial 3D prints and echocardiography showed the difference of accuracy under three different diagnostic methods. The importance of 3D printing for the diagnosis of each case showed the demand for 3D printing at different levels, which showed a difference between complex CHDs and simple CHDs. The questionnaire on which model is better for the diagnosis of the disease showed the suitability of the two models for the diagnosis of each case, which differed in different cases. The questionnaire on which model is more realistic about the structure of the heart showed the similarity of two different models with heart, myocardial 3D printing is generally considered to be more similar to the actual heart.
