We sometimes live with small changes inside our bodies without realizing it, don't we? Sometimes these things are discovered by chance when a doctor does something like a `scan` for something else. That's right, `Atrial Septal Aneurysm` is a small congenital heart condition that often doesn't show any major symptoms. So let's talk about this in a little more detail today, shall we?
What is `Atrial Septal Aneurysm`? Simply put...
Simply put, this is a congenital abnormality of your heart . The wall that separates the two upper chambers of our heart, the atria (also called the atria), has a kind of extra tissue in it. To be precise, part of that wall is weak and bulges out. Sometimes doctors can see this during an echocardiogram, a scan of the heart. Doctors also call this an interatrial septal aneurysm.
Most people have an atrial septal aneurysm, but it does not interfere with the flow of blood through the heart and does not require any special treatment. Although there are no exact statistics on how many people have this condition, it is said to be relatively rare .
Are there types of this?
Yes, there are five main types of `Atrial Septal Aneurysm`. These are classified according to which side of the heart the extra tissue, or protrusion, protrudes more. Think about it, the right side of the heart, the left side, or both sides.
- Type 1R: In this case, the protrusion is towards your right atrium.
- Type 2L: Here the protrusion is towards the left atrium.
- Type 3RL: The protrusion is mostly on the right atrium side, but there is also a small amount on the left atrium side.
- Type 4LR: In this case, the protrusion is mostly on the left atrium side, with a little on the right atrium side as well.
- Type 5: Here the protrusion is almost the same in both the right and left atrium.
While this classification is important to doctors, it's not something you should worry about. What's important is how it affects you.
What are the symptoms of an `Atrial Septal Aneurysm`?
The good news is that most people with an atrial septal aneurysm don't have any symptoms . Your doctor may find it by accident when you have an echocardiogram for another reason.
However, this condition can sometimes be accompanied by other heart conditions, such as irregular heartbeats (arrhythmias), blood clots, or patent foramen ovales (PFOs). If this happens, you may experience symptoms such as:
- Chest pain or discomfort.
- Feeling a change in the speed or rhythm of your heart beating, known as `palpitations`.
- Dizziness.
Why does this `Atrial Septal Aneurysm` occur? What is the cause?
Researchers still don't know exactly what causes an interatrial septal aneurysm. Some doctors and researchers believe it may be caused by genetics or a weakness in the connective tissue in our bodies. However, this is still being researched.
Can this cause other complications?
If you have only one atrial septal aneurysm, it's not a big problem. However, sometimes this condition can increase your risk of other health problems. These include:
- Other congenital heart issues.
- Stroke is a condition in which a blood clot travels to the brain.
- Heart rhythm irregularities (arrhythmias).
- Blood clots.
- A condition called `Patent foramen ovale (PFO)` (this is also a small hole between the atria of the heart).
- A condition called `Atrial septal defect (ASD)` (this is also a hole in the wall between the atria).
Important: These complications don't happen to everyone, but it's because of this risk that doctors are concerned about it.
How do you find out if you have an `Atrial Septal Aneurysm`?
Usually, a doctor can do an `echocardiogram` to see if this is the case. As I mentioned before, if the extra tissue protrudes from the wall between the atria of the heart by more than 10 millimeters (some doctors say 15 millimeters), doctors will diagnose it as an `Atrial Septal Aneurysm`.
Sometimes, if your doctor wants to get a better look at this, he or she may recommend a special scan called a transesophageal echocardiogram (TEE). This involves passing a small camera-like device down your esophagus (food pipe) to get a full view of the wall between the atria of your heart. This can help detect an atrial septal aneurysm that might be missed with a regular echocardiogram (transthoracic echocardiogram - TTE - this is done through the chest).
Most of the time, people don't even know they have an interatrial septal aneurysm. It's usually discovered incidentally during an imaging test of the heart for another reason. These tests include:
- A `CT scan` of the heart (`Cardiac computed tomography (CT)`).
- An MRI scan of the heart (Heart MRI).
- Angiogram test.
If a doctor diagnoses you with an atrial septal aneurysm, they will likely also check for other heart conditions that are associated with it, because, as I mentioned before, some people with this condition may also have other heart conditions.
What are the treatments for this?
If you have an atrial septal aneurysm, but you don't have other heart conditions or risk factors for blood clots and stroke, you probably won't need any treatment . This is true for most people.
However, for some people, doctors may prescribe medications. Treatment for an interatrial septal aneurysm may include blood thinners (such as anticoagulants or antiplatelets). These medications are given to prevent blood clots, as some people with this condition are at a slight risk of developing blood clots.
For some people, especially those with a patent foramen ovale (PFO) and an aneurysm, a minimally invasive procedure called patent foramen ovale (PFO) closure can help reduce the risk of stroke. After this procedure, you may need to take blood-thinning medications called antiplatelets for several months, or even for the rest of your life (especially if you have had a stroke before).
Very rarely, that is, in very limited cases, does this `Atrial Septal Aneurysm` need to be removed with surgery.
How serious is an `Atrial Septal Aneurysm`?
Having an atrial septal aneurysm is not the only cause for concern . It rarely causes a major problem on its own. However, if you have other risk factors for stroke (such as high blood pressure, diabetes, smoking, or having a PFO), then you should also be concerned about an atrial septal aneurysm. This can increase your risk of stroke even further.
Should we fear for our lives with this situation?
In general, the life expectancy of people with an `Atrial Septal Aneurysm` is the same as that of other healthy people . This means that there is no need to worry that this will shorten your life. Not everyone's situation is the same. Your personal situation may vary depending on other diseases or health conditions you have. Therefore, it is best to talk to your doctor about this.
What can you do to take care of yourself?
If your doctor prescribes a medication to help prevent a stroke (such as a blood thinner), it is very important to take it exactly as prescribed, in the dose prescribed, and for the prescribed period of time . Never stop taking your medication or change the dosage without talking to your doctor.
If you have a minor procedure or major surgery, your doctor will take you for follow-up appointments at regular intervals . Be sure to keep these appointments. You may also need to have imaging tests or scans.
When do you need to go to the hospital in an emergency?
This is very important. If you or someone you are with has symptoms of a stroke , you should go to the hospital immediately without delay . Getting treatment early can prevent serious damage from a stroke. Keep these signs in mind:
- It becomes difficult to speak, words get tangled.
- One side of the body (arm, leg, side of the face) suddenly feels numb, tingling, or weak.
- Suddenly, a severe dizziness comes on.
- Vision suddenly becomes blurred, or vision is lost in one or both eyes.
- Suddenly, one or more of our senses stop working (e.g., hearing, smell).
- Suddenly, you feel very confused and like you're forgetting where you are.
- A very severe, sudden headache.
What questions should you ask your doctor?
When you find out that you have an `Atrial Septal Aneurysm`, it is normal to have many questions in your mind. Don't be afraid to ask your doctor about these things:
- "Doctor, do I need any treatment for this `Atrial Septal Aneurysm`?"
- "How soon do I need to see the doctor again (`follow-up appointments`)?"
- "Do I have other heart conditions associated with this `Atrial Septal Aneurysm`?"
- "Given my current condition, what does the doctor think about my future health?"
Finally, what to remember (Take-Home Message)
You may be a little surprised when a doctor tells you that you have an `Atrial Septal Aneurysm`, especially if you have never had any symptoms before. However, in most cases, this is not something to worry about . Most people live normal lives with this condition without any problems.
However, if your doctor says that you are at risk of having a stroke because of this aneurysm, talk to him or her carefully and make a clear plan about what steps you need to take to protect yourself. It is also important to talk to your family, friends at work, and others about the warning signs of a stroke to help ease your fears. Being aware of these signs can be a big help to you or someone you know in the future. Always follow your doctor's advice. Then you can stay healthy!
👩🏽⚕️ Additional questions (FAQs)
💬 Is Atrial Septal Aneurysm (ASA) a bulging blood vessel in the heart?
No! While the word aneurysm sounds like a blood vessel about to burst, 'Atrial Septal' refers to the 'middle wall' (Septum) that separates the two upper chambers (Atria) of the heart. This is a congenital condition in which part of this wall is weak and bulges abnormally to either the left or right, like a balloon filled with air.
💬 Can this wall of my heart, when it's pulled like a balloon, kill me?
Don't worry! This is something that is present in about 1% - 2% of healthy people. In most cases, it does not cause any 'symptoms' throughout life (it is only detected when an Echo Scan is done for something else). Therefore, it does not cause any disruption to the functioning of the heart or pose a fatal danger.
💬 What surgeries are performed to remove this wall?
This does not require any surgery or medication in 99% of cases! But there is one risk, which is the possibility of blood clots forming inside the incision and traveling to the brain, causing a stroke. For that, the doctor will only recommend blood thinners (Aspirin/Blood thinners).
