Tetralogy of Fallot may be diagnosed with fetal echocardiogram (ultrasound). Our Fetal Heart Program will prepare a plan for delivery and care immediately after birth.
Doctors might make the TOF diagnosis before the newborn leaves the hospital if they hear a murmur or see a blue tint to the skin; a primary care pediatrician might detect the same symptoms during a checkup; or a parent might notice TOF symptoms and bring the baby to a doctor or hospital.
Diagnosis of TOF may require some or all of these tests:
- Pulse oximetry – a painless way to monitor the oxygen content of the blood
- Electrocardiogram (ECG) – a record of the electrical activity of the heart
- Echocardiogram (also called “echo” or ultrasound) – sound waves create an image of the heart
- Chest X-ray
- Cardiac MRI – a three-dimensional image shows the heart’s abnormalities
- Cardiac catheterization – a thin tube (catheter) is inserted into the heart through a large vein in the leg
