What is life expectancy for TOF?

The survival data from these two sources were remarkably similar, indicating that 66 percent of persons with tetralogy of Fallot not treated surgically live to age 1 year, 49 percent to age 3 years and 24 percent to age 10 years; thereafter, the hazard function (or instantaneous risk of death) remains constant.

Is tetralogy of Fallot compatible with life?

Historically, children born with TOF didn’t live long enough to need care as adults. However, new treatment technologies are making it possible for these children to live full, active lives.

Is TOF serious?

If TOF is left untreated, it can cause problems with heart rhythms, developmental delays, and seizures. If the condition is never fixed, which is rare, it typically causes death by the age of 20 years old. Usually, a doctor will notice the condition early on and perform surgery to correct the problem.

Is TOF life threatening?

Sometimes, there are defects or problems with the heart when a person is born. These defects are known as congenital heart defects. Tetralogy of Fallot (TOF) is a congenital heart defect that can be fatal if it’s left untreated.

What happens after TOF surgery?

The most frequent problem that occurs after tetralogy of Fallot repair is pulmonary backflow, or leaking from the pulmonary valve. Backflow from the tricuspid valve and aortic valve also can occur. Surgery is needed to repair or replace the leaking valve.

What is the life expectancy with and without repair of TOF?

Tetralogy of Fallot is a rather common complex cardiac malformation with an incidence of 0.1/1000 live births. Without surgical intervention, patients had a 1 year survival rate of 66%, 49% after 2 years and only 10–15% after more than 20 years [1,2].

How is tetralogy of Fallot corrected?

Corrective repair of tetralogy of Fallot involves closure of the ventricular septal defect with a synthetic Dacron patch so that the blood can flow normally from the left ventricle to the aorta.
