Have you ever noticed that some people are much taller than others, their limbs, fingers, etc. seem to be longer than normal? Or do they have an unusual shape of the chest, or have vision problems? Sometimes, along with these symptoms, there can be some problems with the heart and eyes. That is what Marfan Syndrome is. This is a genetic condition. Don't worry, let's talk about this in more detail.
What is Marfan Syndrome? Simply put...
Simply put, Marfan Syndrome is a genetic condition that affects the connective tissue in our bodies. Now you might be wondering what connective tissue is. Think about it, connective tissue is a special type of tissue that connects different parts of our body, such as skin, bones, blood vessels, and heart valves, and helps give them strength and flexibility.
In a person with Marfan syndrome, this connective tissue is a little weak, and it is too elastic . It's like a rubber band, but it has less strength. This is why this condition can affect different systems in the body. It can mainly affect the heart, blood vessels, eyes, bones and joints .
Doctors call this a genetic condition with "variable expression." This means that not everyone with the disease will have the same symptoms. Some people will have very few symptoms, while others will have a few more. And the time it takes for symptoms to appear can vary from person to person.
Marfan syndrome is a condition that is present at birth . However, sometimes symptoms become apparent and you may be a young adult or older when you are diagnosed. It is one of the most common inherited connective tissue disorders. It affects about one in 3,000 to 5,000 people.
What could be the symptoms of this?
Marfan syndrome has two main features. One is an aortic root aneurysm (aortic root aneurysm) . This is a bulge or widening of the main blood vessel that carries blood from our heart to the body (the aorta). The other is a dislocated eye lens (ectopia lentis) .
These two main characteristics can cause you to experience symptoms like:
- Heart palpitations are a feeling of your heart beating faster and your chest pounding.
- Feeling your heart beating loudly and rapidly.
- Eye pain.
- Difficulty breathing.
- Vision changes; for example, astigmatism and extreme nearsightedness.
But because Marfan syndrome can affect other parts of the body, other symptoms may occur. For example, physical symptoms may include:
- The face may appear slightly elongated and narrow.
- The arms, legs, and fingers appear much longer compared to other parts of the body.
- Crowded teeth are teeth that are pulled together and seem to be stacked on top of each other.
- Scoliosis.
- Flat feet.
- Weakness and easy dislocation of joints.
- Stretch marks appear on the skin even if body weight does not change significantly.
- A sunken chest (pectus excavatum) or a protruding chest (pectus carinatum).
- Tall, thin physique.
What are the complications of this condition?
Marfan syndrome can cause various complications that affect your heart, eyes, and lungs.
Cardiovascular complications are the most common complications of Marfan syndrome. These may include:
- Aortic dissection: This is a tear in the inner layer of the wall of your aorta. This is an emergency.
- Heart valve disease: Marfan syndrome can cause the tissue in the heart valves to become weak and flexible.
- Enlarged heart: Over time, your heart muscle can become enlarged and weak.
- Heartbeat irregularities (Arrhythmia): This condition is often associated with mitral valve prolapse.
- Brain aneurysms: A bulging of a weak spot in a blood vessel in or around the brain.
Eye complications can include:
- Cataracts.
- Glaucoma condition.
- Retinal detachment.
Changes in lung tissue associated with Marfan syndrome may increase the risk of:
- Asthma.
- Bronchitis.
- Chronic obstructive pulmonary disease (COPD).
- Collapsed lung / pneumothorax.
- Emphysema.
- Pneumonia.
What causes Marfan syndrome?
This is caused by a genetic variant . Specifically, a change in a gene – the FBN1 gene – that tells our cells to make a protein called fibrillin . This fibrillin is a major component of the elastic fibers in our connective tissues.
In most cases, Marfan syndrome is a condition that is inherited from one of the parents . It is a disease with an autosomal dominant inheritance . This means that the condition can be caused by inheriting the affected gene from only one parent. A person with Marfan syndrome has a 50% chance of passing the condition on to each of their children.
However, in about 25% of cases, this condition can occur due to a new genetic change (for which no cause can be identified), without any family history.
How do doctors diagnose Marfan syndrome?
Because Marfan syndrome affects many different tissues in the body, you may need the help of a team of specialists to diagnose the condition and develop a treatment plan.
First, doctors do these things:
- Ask about your medical history.
- A physical examination will be performed to see if there are any typical symptoms of the disease.
- Asking about your symptoms.
- Ask if anyone in the family has had health problems related to Marfan syndrome.
Doctors usually use a set of criteria called the "Ghent nosology" to diagnose Marfan syndrome. The following tests may be recommended to confirm the diagnosis or rule out other similar conditions:
- CT scan `(Computed tomography - CT scan)`.
- Chest X-ray.
- E.C.G. Test `(Electrocardiogram - ECG)`.
- Echocardiogram.
- MRI scan (Magnetic resonance imaging - MRI)
A genetic test (this is a blood test) can look for changes in the FBN1 gene, which is often responsible for Marfan syndrome. However, the results of these genetic tests are not always clear. This test can also look for other genetic conditions that cause similar symptoms, such as Loeys-Dietz syndrome.
How is Marfan syndrome treated?
There is no cure for Marfan syndrome. However, there are a variety of treatments and methods that can help you manage your symptoms and prevent complications. These include:
- Medications.
- Routine medical monitoring.
- Physical activity guidance.
- Surgery.
You need a treatment plan that is specific to your health problems.
Medicines
Some medications can help prevent or control complications:
- Beta-blockers: These prevent or slow down the enlargement of the large arteries. Doctors recommend starting this treatment as early as possible for people with Marfan syndrome. If you can't take these because of a condition like asthma or because of side effects, your doctor may give you a calcium channel blocker .
- Angiotensin II receptor blockers (ARBs): These medications can also help slow the rate of aortic valve enlargement.
If you have heart valve surgery because of Marfan syndrome, you will need to take anticoagulant medication for the rest of your life.
Constant medical supervision
You should have regular medical checkups for these things:
- Heart and blood vessels – especially the size of your large diaphragm.
- Eyes.
- Skeletal system.
This way, your medical team can monitor changes and identify any potential complications early. They will tell you how often you should come in for these tests.
This monitoring usually includes imaging tests such as:
- CT scans.
- Echocardiograms.
- MRI scans.
Physical activity guidance
Strenuous, strenuous physical activity can put pressure on your diaphragm and other connective tissues affected by Marfan syndrome. Therefore, you should work with a physical therapist to find safe exercises and sports that are right for you.
Doctors usually recommend low- to moderate-intensity exercise, but if you've had surgery on your mitral valve or valve roots, you may need to exercise at an even lower level.
In general, you should avoid things like:
- Activities that involve holding your breath and exerting yourself vigorously (Valsalva maneuver).
- Contact sports.
- Exercise to exhaustion.
- Exercises that involve holding one position for a long time, such as planks and wall sits, are called isometric exercises.
Heart surgery
The main goals of heart surgery for Marfan syndrome are to prevent your aortic valve from dilating or ruptured and to treat valve problems. You and your medical team will decide together whether you need surgery, after considering several factors.
These are the most common surgeries and procedures performed for Marfan syndrome:
- Aortic valve repair or replacement.
- Ascending aortic aneurysm repair.
- Mitral valve repair or replacement.
- Thoracic endovascular aortic repair.
If you need surgery, try to choose a major hospital that has experience with the type of surgery you are having. Your surgical team should also have a good understanding of Marfan syndrome.
What can you expect when living with Marfan syndrome?
If you have Marfan syndrome, you will need to have regular medical appointments and be aware of your body. Marfan syndrome does not affect everyone the same way, so your journey with this condition will be unique to you. Your medical team will help you adapt to the changes in your condition.
Remember, you are not alone. The medical team is always with you.
Due to increased knowledge about Marfan syndrome and improved medical treatments, people with Marfan syndrome are now living longer than they did before the 1970s. The life expectancy of someone with Marfan syndrome is now almost the same as that of someone without the condition. However, the life expectancy of men is significantly shorter than that of women.
Cardiovascular disease remains the leading cause of death in Marfan syndrome. This is especially true for sudden deaths that occur when the disease is not recognized. The risk is also higher in those who receive a late diagnosis.
Marfan syndrome and mental health
There are several things that can affect your mental health and quality of life when living with Marfan syndrome. For example:
- Marfan syndrome is a chronic condition and requires lifelong treatment.
- How this condition affects your appearance.
- Chronic pain and fatigue.
- Restrictions on physical activity (these often also affect social relationships).
- The pressure of family planning.
Because of this, you may be at higher risk for things like:
- Anxiety.
- Depression.
- Experiencing bullying from others.
- Social isolation.
Caregivers and family members of people with Marfan syndrome are also at risk of developing these mental health problems.
Your mental health is just as important as your physical health.
If you are feeling stressed due to Marfan syndrome, don't forget to seek help from a mental health professional, such as a psychologist . You may also find it helpful to join a support group.
Life with Marfan syndrome can feel like a revolving door of appointments, treatments, and lifestyle changes. But every test and every appointment helps you avoid complications from Marfan syndrome and live as healthy a life as possible. Your medical team is with you through it all. Get their support and guidance. If you feel like you're overwhelmed by all of this, seek help from a mental health professional.
