How Is Tetralogy of Fallot Diagnosed? Sometimes, a doctor will diagnose TOF while the baby is still in the mother's uterus when a fetal ultrasound displays a heart abnormality. Your doctor can also diagnose it shortly after birth if they hear a murmur during a heart exam or if the baby's skin color is bluish.

Also asked, when can Tetralogy of Fallot detected?
Tetralogy of Fallot (TOF) is a congenital heart defect that can be diagnosed either before or after a baby is born. Learn more about TOF. At CHOP, Diana had a fetal echocardiogram through the Fetal Heart Program, which performs more than 3,500 such studies each year.
Beside above, how is tetralogy of Fallot repair? 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.
Also Know, what are the signs and symptoms of tetralogy of Fallot?
Signs and symptoms may include:
- A bluish coloration of the skin caused by blood low in oxygen (cyanosis)
- Shortness of breath and rapid breathing, especially during feeding or exercise.
- Loss of consciousness (fainting)
- Clubbing of fingers and toes — an abnormal, rounded shape of the nail bed.
- Poor weight gain.
Can Tetralogy of Fallot be seen on ultrasound?
During Pregnancy Tetralogy of Fallot might be seen during an ultrasound (which creates pictures of the body). Some findings from the ultrasound may make the health care provider suspect a baby may have tetralogy of Fallot. If so, the health care provider can request a fetal echocardiogram to confirm the diagnosis.

Squatting is a compensatory mechanism, of diagnostic significance, and highly typical of infants with tetralogy of Fallot. Squatting increases peripheral vascular resistance (PVR) and thus decreases the magnitude of the right-to-left shunt across the ventricular septal defect (VSD).What are the complications of tetralogy of Fallot?
