Tetralogy of Fallot (ToF)

There are several different heart problems that are in the category of Tetralogy of Fallot. In the most common form, there is a ventricular septal defect and pulmonary stenosis. In Tetralogy of Fallot with Pulmonary Atresia, the pulmonary valve doesn’t open at all. Tetralogy of Fallot with Absent Pulmonary Valve can be very dangerous because the pulmonary arteries become so large and take up so much space in the baby’s chest that the lungs can’t develop properly.
