Tetralogy of Fallot is the most common type of cyanotic congenital heart disease.
If not surgically intervened, patients usually do not live past seven years old. The average life expectancy of children with this disease is only about twelve years.
It is mostly manifested when the child is three to six months old, showing cyanosis.
The face, lips, nails, fingertips, and even the whole body can exhibit cyanosis.
Especially when the child cries, the cyanosis is particularly severe.
Medically, this disease used to be considered incurable. Later, some doctors pioneered cardiac surgery, continuously exploring, and eventually found a surgical method to treat this congenital heart disease.
