In general, patients with congenital heart disease who are cured before the development of complications such as heart failure can survive for a long time without any significant difference from the life expectancy of normal people. Clinically, the survival of patients with congenital heart disease is closely related to the type of congenital heart disease, whether they are treated in time, the effectiveness of treatment and whether they have combined complications. If a patient with congenital heart disease receives regular treatment and is cured in early childhood, the patient’s life expectancy is not significantly shortened and is similar to that of a normal person. If the congenital heart disease is complex, such as Tetralogy of Fallot, and is not treated in time, the patient’s life expectancy will be significantly shortened, and most patients will die before the age of 10. In conclusion, patients with congenital heart disease should be promptly seen by a cardiac surgeon and actively treated under the guidance of a professional doctor, while patients should take rest and avoid strenuous exercise.
