                           Atrial Septal Defect

The atrial septal defect (ASD) is an opening within the wall (septum) between the two chambers that make up the heart (atria). The condition can be present from the time of birth (congenital).

A few small defects may be discovered in the course of a random search and will not cause any problems. Small atrial septal defects are discovered in the early years of childhood.

The hole boosts the quantity of blood that circulates through the lungs. A large, long-standing atrial septal defect can damage your heart and lungs. A procedure or closure of the device could be required to correct atrial septal defect to prevent complications¹.



Many infants who are born atrial septal defect show no symptoms or signs. The signs or symptoms may begin at any time in adulthood.

The symptoms and signs could be:

When is the best time to visit a doctor?

Consult your physician if you or your child is suffering from


heart physiology
Chambers and valves of the heart

It is split into 4 chambers: two on the right side and two left. To circulate circulation of blood through the entire body, it makes use of the right and left sides for various functions.

The heart’s left side transports blood to the lung. Within the lung, blood soaks oxygen, and then is returned to left side. Its left-side pump the oxygenated blood into the aorta, and out to the rest of the body.

Why do heart defects develop?

Doctors have learned that heart problems found in the womb (congenital) result from mistakes at an early stage of the development of the heart and there’s typically no specific root. Genetics and environmental factors may be involved.

The heart’s function is affected by an atrial septal defect

A massive atrial septal defect could cause an increase in blood flow to the lungs and overload that side of the body. If left untreated the right side of the heart will eventually expand and becomes weaker. The blood pressure of your lungs could also increase and cause the condition known as pulmonary hypertension.

There are a variety of atrial septal defects such as:

Risk factors

It’s unclear the reason why atrial septal defects happen however, certain congenital heart problems are known to be prevalent in families and can be found alongside other genetic disorders like Down syndrome. If you’re suffering from a heart defect or have a child who has an issue with the heart or genetic disorder, a genetic counselor will calculate the probability that your the next generation will suffer from one.

Certain conditions that you suffer from during pregnancy may increase your chances of having a child who has a defect in the heart such as:


A tiny atrial septal defect may not cause any complications. A small atrial septal defect is likely to occur during the first few months of life.

Larger defects can cause serious problems, including:

The less frequent serious complications be:

Treatment is a way to prevent or treat many of these problems.

Arial septal defect and pregnancies

A majority of women with an atrial septal defect be pregnant without issues due to the defect. However, having a more significant defect or having complications like arrhythmias, heart failure, or pulmonary hypertension could increase the chance of complications occurring during pregnancy.

Doctors advise women suffering from Eisenmenger syndrome to avoid becoming pregnant, as it may put their lives in danger.

The risk of developing congenital heart disease is more prevalent in children of parents suffering from congenital heart diseases. Anyone who has a congenital heart defect that has been repaired or not, thinking of starting a family must speak with a doctor. The doctor could suggest repair prior to conception.


Most of the time atrial septal problems can’t be avoided. If you’re planning on becoming pregnant, make an appointment with your physician. This appointment should include:



A heart murmur heard during a routine checkup could lead your doctor or the doctor of your child to believe that an atrial septal deficiency, or another heart defect. In the event of a possible heart defect, your physician might recommend some or all of the tests below:



A number of atrial septal defects heal at a whim during the early years of childhood. If they don’t the septal defects may not require intervention. However, many atrial septal deformities eventually require surgery.

Medical monitoring

In the event that you suspect your child is suffering from an atrial septal problem your cardiologist may suggest keeping an eye on it for a while to determine if it heals by itself. The doctor will decide if the child or you requires treatment, based on the condition of your child and whether your child have other heart defects congenital to the child.


Medicines won’t fix the hole However, they could be used to lessen certain symptoms and signs that be associated with an atrial septal hole. They can also be used to lower the risk of complications following surgery. The medications may be used to ensure that the heart beat is regular (beta-blockers) as well as to lower the chance for blood clots (anticoagulants).


Many doctors suggest repairing an atrial septal defect that is discovered in the teen years or in adulthood to avoid the possibility of complications in the future. Surgery isn’t advised when you suffer from an extreme pulmonary hypertension since it can make the problem worse.

Children and adults alike the procedure involves sewing shut or patching the gap between the atria. The doctor will examine your health and decide which procedure to choose from:

Follow-up care

Care for follow-up depends on the nature of the defect, the suggested treatment and if other problems are present. Echocardiograms are repeated after the discharge from hospital after one year and thereafter as directed by you or your child’s physician. For atrial septal defects that are simple and which are repaired during the child’s childhood just a few times, follow-up care typically is required.

Adults who’ve undergone repair of the atrial septal defect need to be monitored throughout their lives to detect any potential complications, like pulmonary hypertension, heart failure, arrhythmias or valve issues. Regular follow-up tests are conducted every year.


Lifestyle Changes

If you’re suffering from an abnormal heart condition that is congenital or have had surgery to rectify it, you could be wondering about restrictions on your activities , as well as other issues.
