With the development of science and technology, especially the development of material science, it is possible to diversify the treatment of congenital heart disease, and the treatment method of congenital heart disease has developed from the previous single surgical treatment to interventional treatment and surgical treatment together. As there are many types of congenital heart disease, the timing and methods of treatment are different. Even for the same congenital heart disease, the timing and methods of treatment are different due to the different size and location of the lesion, at present, some of the atrial septal defects, patent ductus arteriosus and ventricular septal defects can be treated by interventional methods, but most of the congenital heart diseases still need to be treated by surgery. The appropriate timing and method of surgery is an important factor in improving the cure rate of congenital heart disease. For some congenital heart diseases such as transposition of the great arteries, surgery must be performed within the first month of life, while for some congenital heart diseases such as aortic valve leaflet malformation, if the patient’s condition allows, the timing of surgery is best during the period when the child is no longer developing. An experienced cardiac surgeon will provide you with the best timing and options for you to choose from. Parents should not take matters into their own hands without any consultation.
