Congenital heart defect corrective surgeries
Congenital heart defect corrective surgeries fix or treat heart defects that a child is born with. A baby born with heart defects has congenital heart disease. Surgery is needed if the defects are dangerous to the child’s health or well-being.

For more information about risks, how to prepare for surgery, and descriptions of open-heart and closed-heart surgery techniques, see: Pediatric heart surgery.
Patent ductus arteriosus (PDA) ligation
- Before birth, there is a natural blood vessel between the aorta (the main artery to the body) and the pulmonary artery (the main artery to the lungs) called the ductus arteriosus. This opening usually closes shortly after birth. A PDA occurs when this opening fails to close after birth.
- Sometimes the PDA can be closed with a procedure that does not involve surgery. The procedure is usually done in a laboratory that uses x-rays. In this procedure, the surgeon inserts a few small tubes into an artery in the leg and passes them up to the heart. There are no cuts, except for a tiny hole in the groin. Then, a small metal coil or another device is put into the child's arteriosus artery. The coil or other device blocks the blood flow, and this corrects the problem.
- Another method is to make a small surgical cut on the left side of the chest. The surgeon finds the PDA and either ties off the ductus arteriosus, or divides and cuts it. Tying off the ductus arteriosus is called ligation. This procedure may be done in the neonatal intensive care unit (NICU).
Coarctation of the aorta repair
- Coarctation of the aorta occurs when a part of the aorta has a very narrow section, like in an hourglass timer.
- To repair this defect, a cut is usually made on the left side of the chest, between the ribs. There are many ways to repair coarctation of the aorta.
- The most common way to repair this is to cut the narrow section and make it bigger with a patch made of Gore-tex, a man-made (synthetic) material.
- Another way to repair this problem is to remove the narrow section of the aorta and stitch the remaining ends together. This can usually be done in older children.
- A third way to repair this problem is called a subclavian flap. First, a cut is made in the narrow part of the aorta. Then, a patch is taken from the left subclavian artery (the artery to the arm) to enlarge the narrow section of the aorta.
- A fourth way to repair the problem is to connect a tube to the normal sections of the aorta, on either side of the narrow section. Blood flows through the tube and bypasses the narrow section.
- A newer method does not require surgery. A small wire is placed through an artery in the groin and up to the aorta. A small balloon is then opened up in the narrow area. A stent or small tube is left there to help keep the artery open. The procedure is done in a laboratory with x-rays.
Atrial septal defect (ASD) repair
- The atrial septum is the wall between the left and right atria (upper chambers) of the heart. There is a natural opening before birth that usually closes on its own when a baby is born. When the flap does not close, the child has an ASD.
- Sometimes ASDs can be closed without open-heart surgery. First, the surgeon makes a tiny cut in the groin. Then the surgeon inserts tubes into a blood vessel that go into the heart. Next, two small umbrella-shaped "clamshell" devices are placed on the right and left sides of the septum. These two devices are attached to each other. This closes the hole in the heart. Not all medical centers do this procedure.
- Open-heart surgery may also be done to repair ASD. Using open-heart surgery, the septum can be closed using stitches. Another way to cover the hole is with a patch.
Ventricular septal defect (VSD) repair
- The ventricular septum is the wall between the left and right ventricles (lower chambers) of the heart. A hole in the ventricular septum is called a VSD.
- By age 1, most small VSDs close on their own. However, those VSDs that do stay open after this age must be closed.
- Larger VSDs, small ones in certain parts of the ventricular septum, or ones that cause heart failure or endocarditis (inflammation) need open-heart surgery. The hole in the septum is usually closed with a patch.
- Some septal defects can be closed using heart catheterization. This procedure involves passing a small wire into the heart and placing a patch over the defect. It is guided by x-rays.
Tetralogy of Fallot repair
- Tetralogy of Fallot is a heart defect that exists from birth (congenital). It usually includes four defects in the heart and causes the baby to turn a bluish color (cyanosis).
- Open-heart surgery is needed, and it is often done when the child is between 6 months and 2 years old.
- Different types of repairs are done, depending on the defects.
- The ventricular septal defect is one repair, and it is described above.
- The pulmonary valve is opened and the thickened muscle (stenosis) is removed.
- A patch may be placed on the right ventricle and main pulmonary artery to improve blood flow to the lungs.
- The child may have a shunt procedure done first. A shunt moves blood from one area to another. This is done if the open-heart surgery needs to be delayed because the child is too sick to go through surgery.
- A shunt procedure requires making a cut between two of the ribs.
- Once the child is older, the shunt is closed and the main repair in the heart is performed.
- In a normal heart, the aorta comes from the left side of the heart, and the pulmonary artery comes from the right side. In transposition of the great vessels, these arteries come from the opposite sides of the heart.
- Correcting transposition of the great vessels requires open-heart surgery. If possible, this surgery is done shortly after birth.
- The most common repair is called an arterial switch. The aorta and pulmonary artery are divided. The pulmonary artery is connected to the right ventricle, where it belongs. Then, the aorta and coronary arteries are connected to the left ventricle, where they belong.
Truncus arteriosus repair
- Truncus arteriosus is a rare condition that occurs when the aorta, coronary arteries, and pulmonary artery all come out of one common trunk. This is a very complex defect, and it requires complex open-heart surgery to repair it.
- Repair is usually done in the first few days or weeks of the infant's life. The pulmonary arteries are separated from the aortic trunk, and any defects are patched. Usually, there is also a ventricular septal defect, and that is also closed. A connection is then placed between the right ventricle and the pulmonary arteries.
- Most children need one or two more surgeries as they grow.
Tricuspid atresia repair
- The tricuspid valve is found between the upper and lower chambers on the right side of the heart. Tricuspid atresia occurs when this valve is deformed, narrow, or missing.
- Babies born with tricuspid atresia are blue because they cannot get blood to the lungs to pick up oxygen.
- To get to the lungs, blood must cross an atrial septal defect (ASD), ventricular septal defect (VSD), or a patent ductus artery (PDA). (These conditions are described above.) This severely restricts blood flow to the lungs.
- Soon after birth, a medicine called prostaglandin E may be given. This medicine will help keep the patent ductus arteriosus open so that blood can continue to flow to the lungs. However, this will only work for a while. Surgery is needed.
- A series of shunts and surgeries may be necessary to correct this defect. The goal of this surgery is to allow blood from the body to flow into the lungs, and blood from the lungs to be pumped to the rest of the body.
Total anomalous pulmonary venous return (TAPVR) correction
- TAPVR occurs when the pulmonary veins bring oxygen-rich blood from the lungs back to the right side of the heart, instead of the left side of the heart, where this usually occurs in healthy people.
- This condition requires surgery to correct it. When the surgery is done will depend on how sick the baby is. The surgery may be done in the newborn period if the infant has severe symptoms. If it is not done right after birth, it is done in the first 6 months of the baby's life.
- TAPVR repair requires an open-heart surgery. The pulmonary veins are routed back to the left side of the heart, where they belong, and any abnormal connections are closed.
- If a PDA is present, it is tied off and divided.
Hypoplastic left heart repair
- This is a very severe heart defect that results from a severely underdeveloped left heart. If it is not treated, it causes death in most babies who are born with it. Operations to treat this defect are done at specialized medical centers. Usually surgery corrects this defect. A series of three heart operations is usually needed.
- The first operation is done in the first week of the baby's life. This is a complicated surgery where one blood vessel is created from the pulmonary artery and the aorta. This new vessel carries blood to the lungs and the rest of the body.
- The second operation is usually done when the baby is 4 to 6 months old.
- The third operation is done a year after the second operation.
- A heart transplant is another option for this condition. But finding a donor heart for an infant is very difficult. Infant heart transplants can be done only at a few medical centers.
