Pediatric Tetralogy of Fallot (TOF)

The treatment for tetralogy of Fallot is surgery — our heart surgeons have a 100% survival rate in tetralogy of Fallot repair. See our heart surgery outcomes.

Tetralogy of Fallot (TOF or "TET") is a condition of several related congenital (present at birth) defects that occur due to abnormal development of the prenatal heart during the first eight weeks of pregnancy. 

"Tetralogy" refers to four heart problems. The fourth problem is that the right ventricle becomes enlarged as it tries to pump blood past the obstruction into the pulmonary artery.

Normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, then is pumped through the pulmonary artery into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle and then is pumped through the aorta out to the body.
