The survival time of patients with congenital heart disease is closely related to their subtypes and individual differences; different categories will result in different symptoms and different survival times. Usually complex and severe cardiac malformations can develop serious and even life-threatening symptoms soon after birth, while patients with relatively mild congenital heart disease can be asymptomatic for life. Clinically, ventricular septal defect is the most common type of cyanotic congenital heart disease among surviving infants, while others include atrial septal defect, patent ductus arteriosus, pulmonary stenosis, etc. Ventricular septal defects are somewhat self-healing and most patients have a good prognosis. Small atrial septal defects are likely to close spontaneously before the age of 1 year and most can maintain a normal life during childhood. Interventional or surgical treatment of the ductus arteriosus is effective, and the average survival time of untreated patients with tetralogy of Fallot is 12 years. When a child has congenital heart disease, besides cooperating with the doctor for active treatment, parents should also do a good job of home care for the child, such as paying attention to clean skin, bathing regularly in summer and wiping the child’s body with hot towels more often in winter. Try to keep the child quiet, avoid excessive crying, have enough sleep, adjust the diet structure, try to keep the child’s bowels open, prevent constipation, prevent colds, and add and remove clothes for the child in time.
