The life expectancy of patients with congenital heart disease is generally related to the type of congenital heart disease suffered. Children born with complex congenital heart disease, such as single ventricle, permanent arterial trunk, transposition of the great arteries, and double outlet right ventricle, may die before they are two or three years old. Children with tetralogy of Fallot often suffer sudden death due to hypoxia and generally live in their teens, but there are patients who live into their 20s. Children with atrioventricular canal malformations and ectopic pulmonary venous drainage quickly develop pulmonary hypertension, which affects the child’s life expectancy. Simple precordial diseases such as patent ductus arteriosus, atrial septal defect, and ventricular septal defect are more common in adults in clinical practice, and there are patients with atrial septal defect and ventricular septal defect who live into their 50s but have lost the opportunity for surgery and have a poorer quality of life.
