This is sometimes called a Rastelli repair. Sometimes a tube is placed between the right ventricle and the pulmonary artery. The surgeon closes the ventricular septal defect with a patch and opens the right ventricular outflow tract by removing some thickened muscle below the pulmonary valve, repairing or removing the obstructed pulmonary valve and, if needed, enlarging the branch pulmonary arteries that go to each lung. Complete RepairĬomplete repair tends to be done early in life. The shunt is closed when a complete repair is done later. The shunt is usually a small tube of synthetic material sewn between a body artery (or the aorta) and the pulmonary artery. This is not open-heart surgery and doesn't fix the inside of the heart. In some infants, a shunt operation may be done first to provide adequate blood flow to the lungs. Sometimes the first operation is a complete repair. A temporary operation may be done at first if the baby is small or if there are other problems. Tetralogy of Fallot is treated surgically. What can be done about tetralogy of Fallot? The reason is that some oxygen-poor blood is pumped to the body through the hole in the wall between the right and left ventricle instead of being pumped to the lungs. Infants and young children with unrepaired tetralogy of Fallot are often blue (cyanotic). How does tetralogy of Fallot affect my child? Sometimes the pulmonary valve is completely obstructed (pulmonary atresia). Obstruction in the pulmonary valve leading from the right ventricle to the lung artery prevents the normal amount of blood from being pumped to the lungs. In a child with tetralogy of Fallot, blood can travel across the hole (VSD) from the right pumping chamber (right ventricle) to the left pumping chamber (left ventricle) and out into the body artery (aorta).
Normally the left side of the heart only pumps blood to the body, and the heart's right side only pumps blood to the lungs. Some children can have other heart defects along with tetralogy of Fallot. It may be seen more commonly in children with Down syndrome or DiGeorge syndrome. In most children, the cause of tetralogy of Fallot isn't known.
