With the rapid development of cardiac surgery, surgical methods have been improved, medical equipment has been perfected, and the range of indications for surgery has been expanded, so that almost all congenital heart diseases can be surgically corrected. Most of the common non-cyanotic congenital heart diseases can be radically operated with good results. For example, the success rate of surgery for pulmonary stenosis, atrial septal defect, ventricular septal defect, patent ductus arteriosus, and aortic stenosis is more than 98%. The success rate of surgery for cyanotic congenital heart disease is slightly lower, but the success rate of surgery for the common tetralogy of Fallot can also reach more than 95%. The success rate of surgery for certain congenital heart diseases with complex malformations, such as single ventricle and complete pulmonary vein malformation drainage, is also above 80%. Children who were previously inoperable can now be treated surgically. Some serious heart diseases can now be treated surgically in the neonatal period (within 1 month after birth). The vast majority of children with precardiac disease have normal body parts except for the heart malformation. If the heart malformation is corrected by treatment, it is entirely possible for them to experience normal growth and development and live, study and work as normal people. For some patients who have lost the time of surgery, such as those who have combined organic pulmonary hypertension, the pulmonary vessels have irreversible lesions and the intracardiac malformation cannot be corrected, otherwise it may produce pulmonary hypertensive crisis such as accelerated heart rate, reduced blood pressure, hypoxemia and finally death. For such patients, lung or heart-lung transplantation is required. With the development of medical science, all congenital heart diseases can be improved by surgery to improve the quality of life of patients. And most of the congenital heart diseases will become more and more complicated and serious if the heart malformation is not treated. So early detection, early diagnosis and early treatment is the key.
