Tetralogy of Fallot (ToF) is a cyanotic congenital heart disease caused by anterior displacement of the aorticopulmonary septum, causing unequal division of the truncus arteriosus. This causes four separate malformations, hence the name “tetralogy”:
- Pulmonary infundibular stenosis (narrow right ventricular outflow tract)
- Ventricular septal defect
- An overriding aorta
- The aorta originates right over the VSD, so blood from the right ventricle enters the aorta during systole
- Right ventricular hypertrophy
Diagnosis and evaluation
Echocardiography confirms the diagnosis. Chest x-ray would show a boot-shaped heart.
