What It Is Tetralogy of Fallot has four key features. The reason is that some oxygen-poor blood is pumped to the body. Surgical Treatment Tetralogy of Fallot is treated surgically. A temporary operation may be done at first if the baby is small.
Complete repair comes later.
Sometimes, the first operation is a complete intracardiac repair. In small and very blue infants, a shunt operation may be done first to provide adequate blood flow to the lungs. This lets the baby grow big enough to have a full repair. The shunt is built between the aorta and the pulmonary artery. The shunt is removed when a complete intracardiac repair is done later.
