The treatment of simple precordial disease requires an individualized program. Tailor-made to get the most perfect result. The first issue is the diagnosis: even for simple diseases, the ultrasound report is only referenced by a specialized cardiology hospital. The important thing in the report form is the description and the data. Simply transcribing the diagnostic conclusion is not very meaningful. Second, whether treatment is needed: many simple precordial diseases, is not necessary to treat. Observation, is also a method, many precordial diseases have little effect on the child, the future may heal itself, or may become increasingly serious, regular review, heavy, and then treatment is too late. Third, when to treat: not all precordial disease, found to be treated. Many parents, as soon as they find out that their children have precordial disease, they are very anxious, which is understandable. But on the other hand, the child is not very well before the discovery of precocious heart disease. Many treatment, the child is older, the risk is much smaller. Of course, the child’s state is not good, a wait, will be delayed. Fourth, how to treat: intervention or open-heart surgery: the intervention of internal medicine, is non-invasive. Non-invasive, that is, there is no trace on the surface of the body, then, the child will not have any psychological impact after adulthood. It is certainly the best choice. The indications for interventional treatment are also very strict, and if it is not successful, surgery will be done instead. Nowadays, many small and medium sized companies carry out “minimally invasive” treatment, and I think that the majority of those who can do minimally invasive treatment can be treated non-invasively. Therefore, we only do “minimally invasive” in adults with poorly positioned atrial defects. Fifth, whether small incision: the advantages of small incision surgery on the right side of the chest, not here to elaborate. It is important to emphasize that if the child is very sick and young, there may be intraoperative variables. It is also not suitable for small incision surgery. A few years ago, there was no such method, and the children were not all healthy.
