Tetralogy of Fallot Underlying Cause
- Ventricular septal defect:
- A hole in the septum that separates the ventricles
- Pulmonary stenosis:
- An obstruction in blood flow from the right ventricle to the lungs
- Overriding aorta:
- The opening to the aorta communicates with the ventricular septal defect. This causes oxygen-poor blood to be pumped to the body.
- Right ventricular hypertrophy:
- A thickened and enlarged right ventricle
