Atrial Septal Defect (ASD) Repair

Holes in the heart are a type of congenital heart disease. Ventricular septal defect (VSD) and atrial septal defect (ASD) are the two most common congenital defects that may affect an individual. These occur due to structural malformation in the walls of the heart when these are developing at the fetal stage. ASD and VSD can be repaired and closed as soon as they are identified or right after birth. ASD is the hole in the septa that divides the two atrium and VSD refers to the hole in the ventricular walls. The holes allow the reverse flow of blood, thus, facilitating the mixing of pure and impure blood.

  • To understand the holes in heart we must briefly understand the working of the heart. The heart works like a pump beating on an average of 100,000 times in a day. It has two sides which are divided by a wall called septum. The right side of the valve pumps blood to the lungs and picks up oxygen. The oxygen-rich blood then returns to the left side of the heart from the lungs and then the left side pumps it to the rest of the body.
  • These two sides are divided into 4 chambers having four valves connecting them to various blood vessels. For carrying blood from the body to the heart, veins are responsible while arteries carry the blood away from the heart to be circulated to the body. The atria are two upper chambers that collect blood while ventricles are the two lower chambers pumping the blood to the lungs and other parts of the body.
  • The valves act like doors allowing a flow of blood through the next chamber to arteries and then they close to keep the blood from again returning back to the previous chamber from where it came. In a systolic contraction, the ventricles pump blood from the heart and in a diastolic contraction, the ventricles relax to receive blood pumped by the atria. The aortic and pulmonary valves close at the beginning of the diastole to prevent the chances of backflow. Thus, the presence of a hole in the septa may lead to mixing of the blood and interfere with the normal flow of blood circulation in the body.
  • An ASD is naturally present when the baby is still a fetus. But the hole closes on its own by the time of birth. However, in some cases, it may persist even after birth. An ASD can be of different types, including sinus venosus atrial septal defect, mixed atrial septal defect, ostium secundum atrial septal defect. A VSD, on the other hand, is usually detected in a baby or in an adult when a doctor observes a heart murmur. Certain tests such as an echocardiogram or electrocardiogram are performed to confirm its presence.

Typically, medications are administered to see whether ASD or VSD closes on its own. In case the defect does not close on its own and the individual continues to experience atrial septal defect symptoms such as breathing difficulties, heart murmurs, shortness of breath, and respiratory infections, then a surgery is recommended. The surgical procedure for atrial septal defect repair and ventricular septal defect treatment are almost the same, except the fact that different parts of the heart are targeted during the surgery.

Balloon Angioplasty
Balloon Atrial Septostomy

Balloon Atrial Septostomy is a procedure performed primarily for children and infants. It is a procedure where a small hole is made in the wall between the left and right atria of the heart. The hole is made using a cardiac catheter. Atrial Septostomy reduces the pressure on the right side of the heart, allowing the heart to pump more efficiently. This improves blood flow to the lungs. It is often performed on children with transposition of the arteries. It helps in receiving oxygen-rich blood throughout the body. It is also performed to treat congenital heart defect known as Hypoplasic left heart syndrome where the left side of the heart is severely under-developed.

Device Closure of ASD (Amplatzer Septal Occluder)
PDA Closure

Patent ductus arteriosus (PDA) is a heart disorder first diagnosed or observed during the first few weeks or months of the surgery. This condition is characterized by the persistence of a normal fetal connection between the pulmonary artery and the aorta, which may allow the flow of some of the oxygenated blood back to the lungs instead of the body.

This connection is naturally present in the fetus during pregnancy. It is, in fact, present at the time of birth as well But it closes off on its own within a few days.

During pregnancy, all of the oxygen demand of the fetus is met through the placenta. Therefore, there is no need for the blood to go through the lungs for oxygenation. However, a connection is necessary to let oxygenated blood bypass the lungs of the fetus and reach the body. This connection is known as ductus arteriosus (DA).

As soon as the baby is born, the lungs take over the functioning of the connection and start purifying the blood. The problem arises when the connection does not close on its own within a few days after the birth. This condition is known as PDA.

The exact reason why DA remains open (patent) is some infants is still unknown. However, girls are twice as likely to suffer from PDA as boys. Additionally, PDA may occur in combination with other heart defects as well.

PDA, if left untreated, may lead to a number of complications. Because of the flow of oxygenated blood from the aorta to the pulmonary artery and the mixing of blood, the vessels of the lungs have to handle a large amount of blood. The larger the volume of blood that enters the pulmonary artery, the greater they have to cope with the increased pressure. This may lead to long-term damage to the lungs.

PDA may cause no symptoms at all in some children. However, the following are some of the symptoms experienced by a majority of children with PDA:

  • Heavy, congested, or rapid breathing
  • Fatigue
  • Sweating
  • Poor weight gain
  • No interest in feeding
  • Excessive tiredness while feeding
