This picture demonstrates the four defects (numbers 1-4) found in Tetralogy of Fallot all the 4 defects contribute to poor oxygenation of blood.
1. Pulmonary Stenosis: The small pulmonary vessel causes less blood to enter to the lungs.
2. Displacement of the aorta: The displacement allows the aorta to receive both oxygenated and deoxygenated blood.
3. Ventricular Septal Defect: Allows deoxygenated blood to cross from the left side of the heart to the right side, or the opposite way (depending on pressure differences between left and right ventricles).
4. Right Ventricular Hypertrophy: Due to pulmonary stenosis, right ventricle must pump harder to compensare.
