Do you sometimes feel chest pain, shortness of breath, or dizziness? Or do you suddenly feel faint or dizzy? These may be caused by a narrowing of one of the important valves in your heart, the aortic valve. Doctors call this condition Aortic Stenosis. When this happens, it becomes difficult for the heart to pump blood to the rest of the body. The body does not get enough oxygen. This is not something you can wait for, as it can damage the heart, cause serious health problems, and sometimes even be life-threatening.
So what is this `(Aortic Stenosis)`?
Simply put, our heart is like a small house, it has four chambers. Between these chambers, where blood flows out of the heart, there are parts like doors. We call these heart valves. One of these four valves is called the Aortic Valve. This is the last gate through which blood passes from the heart to the rest of the body. Like a gatekeeper, this gate only lets blood flow in one direction and stops it from flowing back into the heart. This Aortic Valve has three small flaps (leaflets). If these flaps do not open properly and become blocked or narrow, then a condition called Aortic Stenosis occurs.
Think of it like a water pipe that gets stuck in the middle and has difficulty draining. It's normal to feel a little scared when you hear about a problem with this entrance. But there are now many advanced methods to treat this condition , so there's no need to worry.
How common is this condition (Aortic Stenosis)?
This condition called `(Aortic Stenosis)` is actually quite common among people over the age of 65. But sadly, many people don't know they have this condition until the symptoms become severe. Sometimes it is discovered during tests done for another condition. Some diseases can cause this condition in middle age, around the age of 40-50. Very rarely, this `(Aortic Valve Stenosis)` can also occur in young children as a ``Congenital condition``.
What are the symptoms of this?
Not everyone with Aortic Stenosis will have symptoms right away. Some people may not notice anything for years. But when the condition is more severe, symptoms such as these may appear:
- Feeling extremely tired: You may feel so tired that you can't even do your usual tasks.
- Palpitations: You may hear your heart beating, or you may feel it beating very fast, or your chest may feel like it's pounding. We call this ``Palpitations''.
- Swelling of the legs and ankles: The lower parts of the legs and around the ankles may swell.
- Chest pain: This is what is called `(Angina)`. It can feel like a squeezing, tightening, or heaviness in the chest. Sometimes this pain can radiate to the neck, jaw, left arm, or even the side of the stomach.
- Difficulty breathing: You may have difficulty breathing, especially when you are slightly tired, or even just when you are at rest.
- Dizziness, fainting: You may feel dizzy, your eyes may turn blue, and you may even faint.
Remember, just because you have these symptoms doesn't mean you have Aortic Stenosis. But if you continue to have them, you should definitely see a doctor . Your primary care provider may refer you to a cardiologist.
How quickly can this disease become serious?
This is different for everyone. For some people, this `(Aortic Valve Stenosis)` gets worse slowly, over years. For others, it can get worse very quickly, even in a few months. The important thing is, if you delay getting treatment, you may not be able to repair the damage to your heart. If you have severe `(Aortic Stenosis)`, there is a risk of sudden cardiac death. That is why your doctor will tell you not to delay treatment if you have symptoms.
Why does this `(Aortic Stenosis)` occur? What are the causes?
There are three main reasons why adults develop Aortic Stenosis:
1. Age-related degeneration: This is the most common cause. Over time, like limescale in water pipes, calcium can build up in your heart's aortic valve. This causes the valve to thicken and become blocked, preventing it from opening and closing properly. This often happens after the age of 65.
2. Damage from infections: If some bacterial infections are not treated properly, the bacteria can enter the bloodstream and travel to the heart valves. Our own immune system can then damage these valves. For example, if a throat infection (Strep throat) or Scarlet fever is not treated properly, a disease called Rheumatic fever can develop and damage the heart valves. This damage can take years, sometimes decades, to become apparent. This most often affects people over the age of 50.
3. Other hereditary or chronic diseases: Rare diseases such as `(Paget's disease of the bone)` (a disease related to bones), kidney failure (`Kidney failure`) and `(Familial hypercholesterolemia)` (a condition of high cholesterol that is inherited) can also cause `(Aortic Valve Stenosis). Also, this risk is higher in people with autoimmune diseases such as `(Lupus)` and `(Rheumatoid arthritis)`.
Are there other risk factors for this?
Yes, there are several other factors that increase the risk of developing `(Aortic Valve Stenosis):`
- Being a man.
- Being over 65 years of age.
- Increased cholesterol levels in the blood (Hyperlipidemia).
- Having high blood pressure.
- Use of tobacco products (like cigarettes, beedis).
What are the complications that can occur due to this `(Aortic Stenosis)`?
When you have `(Aortic Stenosis)`, the heart has to work very hard to push blood through that narrowed opening. It's like trying to push open a stuck door. When the heart works too hard in this way, it can weaken over time. This is why:
- Heart attack
- Heart failure ( inability of the heart to pump enough blood to the body)
- Sudden cardiac death
- Pulmonary hypertension
- Excessive bleeding
- An infection of the inner lining of the heart (`Infective endocarditis`)
Serious complications can occur.
How do doctors recognize this?
If you suspect you have Aortic Stenosis, a cardiologist will examine you. The condition is usually diagnosed based on your symptoms (if any) and one or more of the following tests:
- Physical examination: The doctor will check your legs and ankles for swelling, then listen to your heart with a stethoscope. If you have aortic stenosis, a heart murmur is a common sign.
- ECG test (`Electrocardiogram - ECG or EKG`): This measures the electrical activity of the heart.
- Chest X-ray, Angiography, or Cardiac CT scan: All of these use X-rays or other techniques to look inside the body, especially the heart and lungs.
- Echocardiogram: This is the main test used to diagnose aortic stenosis. It uses ultrasound waves to clearly see how the heart valves are working, whether they are blocked, and how blood is flowing.
- Exercise stress testing: Measures things like how your heart works and changes in your ECG while you run on a treadmill or ride a bike.
- Cardiac catheterization: In this procedure, a doctor inserts a small, thin tube (catheter) into a vein in your arm or leg and threads it into your heart to measure the pressure in your valves and see how tight they are.
- Heart MRI (Magnetic Resonance Imaging): A strong magnetic field can be used to take very detailed pictures of the heart.
After these tests, your doctor will classify your condition based on your symptoms and how narrowed your aortic valve is. There are usually four stages: A, B, C, and D, with D being the most severe.
What are the treatments for `(Aortic Stenosis)`?
If you have `(Aortic Stenosis)` but no symptoms, meaning the condition is not that severe, your doctor will tell you to come for regular check-ups and have `(Echocardiogram)` tests. But if you develop symptoms, then you will need treatment. There are several main treatment options:
- Medications: If the condition is not too severe, doctors may prescribe medications to control the symptoms. These may include blood thinners, diuretics, and medications for heart rhythm disorders, high blood pressure, and heart failure. But remember, medications only control the symptoms; they cannot stop the valve from getting worse.
- Valve repair: This can be done through surgery or a procedure called balloon valvuloplasty.
- Surgical repair (`Aortic valve surgery`): A surgeon makes an incision in your chest and goes directly to the heart valve, relieves the blockage, and repairs it.
- Balloon valvuloplasty: In this procedure, a balloon with a small tube (catheter) inserted into the heart is inflated inside the narrowed valve, widening the valve. This can temporarily relieve symptoms. It is often done for people who cannot have valve replacement surgery, or as a temporary relief before surgery.
- Valve replacement: If the valve is too damaged to be repaired, it will need to be replaced. There are several methods for this:
- Aortic valve replacement surgery: The damaged valve is removed and replaced with a new valve. This new valve can be a human donor (usually a deceased donor), a bioprosthetic valve (usually a cow or pig), or a mechanical valve made of metal.
- Ross procedure: This is a special surgery. In this, your own pulmonary valve is taken and transplanted to the place where the aortic valve used to be. Then, a valve from a donor is inserted in the place where the pulmonary valve used to be.
- Transcatheter Aortic Valve Replacement (TAVR or TAVI): This is the newest and most advanced procedure. It is a major surgery, meaning that the valve can be replaced without opening the chest. A small tube (catheter) is inserted through a large vein in the leg or arm, and a folded valve is passed through it to the heart, where it is fixed inside the blocked aortic valve. This is often done for older people who cannot tolerate major surgery.
How long does it take to recover after these treatments?
This varies depending on the treatment method used.
- If you have surgery: It takes some time to recover. You will usually have to stay in the hospital for a few days. Even after you go home, it may take a few weeks, or even a month, to fully recover and resume normal activities.
- If you have had procedures like Balloon valvuloplasty or TAVR: These procedures require a very short recovery time. You can sometimes go home the same day or the next day after the procedure. You can return to your normal life within a few days.
Is there a way to prevent the development of this `(Aortic Stenosis)`?
Aortic Stenosis can be prevented for some reasons. In particular, it is very important to treat bacterial infections quickly and properly. For example, if you have a strep throat infection, you should take antibiotics exactly as prescribed by your doctor. It is not a good idea to stop taking them just because the pain has subsided. Doing so can prevent rheumatic fever from developing and damaging the heart valves.
However, it is often difficult to prevent ``Aortic Valve Stenosis'', which can be caused by aging, hereditary diseases, or some chronic diseases. However, following a heart-healthy lifestyle (good diet, exercise, and avoiding smoking) can help control the worsening of the condition.
If I have `(Aortic Stenosis)`, what should I expect?
The future of your Aortic Stenosis condition, that is, how you will fare, will largely depend on how quickly and properly you receive treatment.
- If left untreated: Aortic Stenosis, especially if it is severe, can be life-threatening. Most people do not survive more than a few years without treatment.
- Delayed Treatment: If treatment is delayed, the results are mixed. It depends on whether permanent damage has occurred to the heart. The more damage there is, the worse the condition will get. You will recover to some extent, but it is difficult to expect a complete recovery.
- If treated promptly or promptly: If treated promptly and properly, the outlook for `(Aortic Stenosis)` is very good. You will need to go for regular check-ups under medical supervision for the rest of your life, but otherwise you can resume almost all of your normal activities and live a good life.
How do I take care of myself?
- If your aortic stenosis is mild and you have no symptoms, all you need to do is have regular echocardiograms and see your doctor.
- If you have moderate Aortic Valve Stenosis, you may need to monitor your symptoms, have regular echocardiograms, limit your activities (as directed by your doctor), and take certain medications.
- If you have severe aortic valve stenosis, you will need to continue seeing your doctor even after a valve repair or replacement. Some medications may need to be taken for the rest of your life.
- At all levels, your doctor will tell you to eat a diet low in salt and fat, and to exercise regularly. But you should ask your doctor what level of exercise is right for you.
When should I see my doctor?
Whether you have decided not to seek treatment or have not yet received treatment, you should talk to your doctor immediately if any of the following occur:
- Whether a new symptom of `(Aortic Stenosis)` appears, or if existing symptoms suddenly worsen.
- If your symptoms start to interfere with your daily life.
When should I go to the emergency room (ER)?
After starting a new medication, go to the emergency room if any of the following happens:
- If you experience an unexpected, severe side effect from a medication (your doctor will tell you which side effects require immediate medical attention).
- If you faint or lose your sleep for any reason, it's okay.
- If you take blood thinners and fall, you are at a higher risk of internal bleeding - especially after a fall or other injury.
Whether after surgery or a catheter procedure, go to the emergency room if any of the following occurs:
- If your incision is red, swollen, or hot to the touch, these are signs of an infection that needs immediate treatment.
- If you have severe symptoms of Aortic Stenosis, such as difficulty breathing, chest pain, rapid heartbeat, or fainting.
- If you take blood thinners and fall, it's for the same reason mentioned above.
What questions should I ask my doctor?
When you go to see a doctor, don't hesitate to ask questions like these:
- Doctor, do you think my symptoms will get worse?
- Will I have to replace a valve?
- What kind of valve is best for me to replace?
- When is the best time for me to have surgery?
- What are the latest treatments for this?
