After heart repair surgery, the life expectancy of the patient is similar to that of a normal person, and young patients have no problem surviving for decades. Heart repair is mainly used to treat congenital heart diseases, such as atrial septal defect, ventricular septal defect, and patent ductus arteriosus. These common congenital heart diseases can be repaired through interventional or surgical procedures at the right stage to restore the heart defect to normal, provided they are detected in time. With timely treatment, the heart functions exactly as normal and therefore life expectancy will not be affected in any way. Therefore, patients with congenital heart disease should undergo surgery or interventional treatment as early as possible as soon as it is detected, and complete cure can be achieved.
