Tetralogy of Fallot
- Ventricular septal defect (VSD) —A hole in the heart. It is on a wall that separates the two lower chambers.
- Overriding aorta—The aorta, which is the body's largest artery, comes out of the left ventricle, but partially covers or comes out of the right ventricle
- 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.
