The life expectancy of complex congenital heart disease has not been definitively established. According to foreign statistics on the life expectancy of congenital heart disease, the average life expectancy of a patient with a large congenital atrial septal defect without any treatment is approximately 36 years; for a congenital ventricular septal defect without any treatment, the average life expectancy is approximately 40 years. Therefore, if a child has complex congenital heart disease, parents should not give up. With the existing medical conditions, minimally invasive surgery and surgery can be performed for congenital heart diseases, so the disease needs to be treated actively.
