The specific life expectancy of congenital heart disease depends on the specific condition of congenital heart disease, like atrial septal defect, the prognosis is generally good, the average natural life expectancy can reach 50 years, some patients can live up to 70 years. If the defect is large, it is prone to pulmonary hypertension and heart failure, and the prognosis is poorer. In particular, the prognosis is worse for defects in which the first foramen is not closed. Like ventricular septal defects, those with small defects also have a good prognosis and a natural life expectancy of 70-80 years. Small defects may close on their own before the age of 10 years, while large defects may have heart failure at the age of 1-2 years but may improve later, but children with pulmonary hypertension also have a poor prognosis. Therefore, it is important to master the daily care of congenital heart disease, suggesting a reasonable life, reasonable medication, prevention of infection, and regular review so that the child can safely reach the age of surgery.
