Tetralogy of Fallot
- Ventricular septal defect (VSD) —A hole in the heart. It is on a wall that separates the two lower chambers.
- Transposition—A major blood vessel (aorta) is in the wrong place.
- Pulmonary stenosis—The valve in the heart that allows blood to pass from the heart toward the lungs is too narrow.
- Right ventricular hypertrophy—The muscle on the right side of the heart is too thick.

- Loud heart murmur —a sound caused by chaotic blood flow through the heart, can be heard through a stethoscope
- Blue coloring of the skin and lips caused by a low oxygen level in the blood
- Shortness of breath and rapid breathing—caused by a low oxygen level in the blood
- Older children may have shortness of breath and fainting spells when they exercise.
- Lips and skin become very blue
- Baby will become breathless and irritable
- Baby may become sleepy or unconscious if low oxygen levels continue
- Older children may squat with their knees on their chest to help recover from the breathlessness
- Chest x-ray —a test that uses radiation to take a picture of structures inside the chest
- Echocardiogram —a test that uses sound waves to examine the size, shape, and motion of the heart
- Cardiac catheterization —a tube-like instrument is inserted through a blood vessel into the heart to detect problems with the heart
- Closing the hole in the heart. A patch will be placed over the hole.
Improving the flow of blood from the heart to the lungs by one or more of the following:
- Removing some of the thickened heart muscle on the right side of the heart
- Repairing or replacing the valve that allows the blood to flow from the heart to the lungs
- Increasing the size of the blood vessels that carry blood to the lungs
