17211 Marfan Syndrome Heart Surgery

Overview

Marfan syndrome is a genetic condition that affects the body's connective tissue. Connective tissue is like the glue that supports your bones, muscles, organs, and blood vessels. In Marfan syndrome, this tissue is weaker than usual. This can affect many parts of the body, especially the heart and blood vessels. Sometimes, this weakness can make the main artery from the heart (called the aorta) stretch wider over time, which may lead to the need for heart surgery to prevent problems.

Marfan syndrome is rare. It is thought to affect about 1 in 5,000 people. It affects people of all backgrounds and races, and both men and women equally.

Marfan syndrome can affect anyone, but it often runs in families. If one parent has the gene, each child has a 50% chance of inheriting it. In some people, it happens as a new gene change with no family history. The condition can affect children, teenagers, and adults, and it often becomes more noticeable during growth spurts.

Symptoms

Common symptoms

• Being unusually tall and thin, with long arms, legs, fingers, and toes
• A chest that sinks in or sticks out
• A curved spine (scoliosis)
• Flat feet or very flexible joints
• Stretch marks on the skin that appear without weight change
• Heart palpitations (feeling like your heart is racing or skipping beats)
• Shortness of breath, especially with activity
• Chest, back, or abdominal pain
• Eye problems, such as nearsightedness or lens dislocation

Symptoms in children

• Rapid growth and being much taller than classmates
• Curvature of the spine or chest shape differences
• Unexplained joint pain or loose joints
• Vision problems, like blurred vision or a lazy eye
• Heart murmur (found during a check-up)
• Family history of Marfan syndrome or sudden heart problems

Symptoms in older adults

• Shortness of breath when climbing stairs or walking
• Fatigue and reduced ability to exercise
• Heart palpitations or irregular heartbeat
• Back or abdominal pain that may feel like a tearing sensation
• Blood pressure problems
• Foot pain or joint pain from loose connective tissue

Causes

Main causes

• A change (mutation) in the FBN1 gene that provides instructions for making a protein called fibrillin-1. This protein is important for connective tissue strength and elasticity.
• The weakened connective tissue can cause the aorta to stretch and enlarge, a condition called aortic aneurysm.
• The gene change can be inherited from a parent, or it can happen for the first time in a person with no family history.

Risk factors

• Having a parent or sibling with Marfan syndrome
• Having a family history of an enlarged aorta or unexplained early heart problems
• Going through rapid growth spurts in childhood and teenage years, which may make symptoms more noticeable

When to see a doctor

See a doctor urgently if:

• If you or your child have any symptoms listed under 'call for emergency help', call your local emergency number immediately. Do not wait.
• If you have Marfan syndrome and you have new chest or back pain, go to the emergency department right away.

Book a routine appointment if:

• See your GP (general practitioner) if you are worried about physical features like very long limbs, chest shape, or vision problems.
• If you have a family history of Marfan syndrome, ask your GP about a referral to a specialist for heart and eye checks.
• For people already diagnosed with Marfan syndrome, keep all appointments with your cardiologist (heart specialist) and eye specialist.

Diagnosis

Doctors diagnose Marfan syndrome by looking at your medical history, doing a physical examination, and using tests. There is no single blood spot test that everyone uses, but a genetic test can help. A specialist team often works together to make the diagnosis.

Tests that may be done

• An echocardiogram (ultrasound of the heart) to look at the size of the aorta and how well your heart valves are working
• A CT scan or MRI of the chest to get a clearer picture of the aorta
• A detailed eye exam (using a special microscope called a slit lamp) to check for lens dislocation
• A genetic test (a blood sample) to look for a change in the FBN1 gene
• A physical exam to measure your arm span, leg length, and spine curvature

What to expect at your appointment

If your GP thinks you might have Marfan syndrome, they will refer you to a specialist – often a cardiologist and an ophthalmologist (eye specialist). You may also see a geneticist (a doctor who specialises in genes). The process can involve several appointments, and it is okay to ask questions at any time. The team will explain your care plan based on your results.

Treatment

There is no cure for Marfan syndrome, but there are very effective ways to manage it and reduce the risk of serious heart problems. The main goal is to protect the aorta from becoming too large or tearing. Treatment usually involves regular check-ups, lifestyle adjustments, and sometimes medicines or surgery.

Self-care at home

• Keep all your follow-up appointments – these are vital for keeping track of your aorta and heart.
• Avoid heavy lifting, pulling, or straining exercises (like weightlifting or intense contact sports).
• Learn to do gentle exercise that does not over-stress your heart or joints.
• Take care of your eyes – have regular eye exams and report any vision changes.
• Tell your doctors and dentist that you have Marfan syndrome, especially before any surgery or dental work.

Medical treatments

Your doctor may prescribe medicines that help lower your blood pressure and reduce stress on the aorta. These medicines are usually taken daily. The choice of medicine depends on your age, your blood pressure, and the size of your aorta. Do not change or stop any prescribed medicine without talking to your doctor. Your doctor may also suggest antibiotics before certain dental or surgical procedures to protect your heart valves.

When is surgery considered?

Heart surgery may be recommended if your aorta becomes very wide, or if it is growing quickly, because this raises the risk of a torn aorta (dissection). Surgery usually replaces part of the aorta with a synthetic tube, called a graft. Sometimes the aortic valve can be repaired or replaced at the same time. The decision to operate is based on the size of the aorta, your age, and your overall health. Your heart surgeon will explain the options and what to expect.

Living with this condition

Living with Marfan syndrome means staying on top of your health. Most people feel well day to day, but they need to be careful. It helps to know your body and to tell your doctor about any new symptoms. You can still study, work, and enjoy hobbies – you just need to choose activities that are safe for your heart and joints.

Lifestyle tips

• Do not smoke or use tobacco – smoking damages blood vessels and raises heart risk.
• Avoid heavy lifting and activities like basketball, football, gymnastics, or weightlifting that put sudden strain on the chest.
• Choose gentle exercises like walking, swimming, or cycling, with your doctor's approval.
• Maintain a healthy weight to reduce stress on your heart and joints.
• Manage stress with relaxation methods, hobbies, or talking things through with friends.

Diet and exercise

A balanced diet helps. Try to eat plenty of fruits, vegetables, whole grains, and lean protein. It is wise to limit salt to keep blood pressure in a healthy range. Regular, moderate exercise is good, but always check with your doctor first. Avoid competitive or high-impact sports that could risk injury or strain your aorta.

Mental health and emotional wellbeing

Getting a diagnosis of Marfan syndrome can feel overwhelming. It is normal to feel anxious, sad, or uncertain. Talking to a counsellor or a trusted friend can be a great help. Some people find comfort in connecting with others who have Marfan syndrome. Remember that your medical team is there to support you, and you are not alone.

Prevention

Marfan syndrome cannot be prevented because it is caused by a gene change. However, you can prevent many of the serious complications by finding out early and following your care plan. For people with a family history, genetic counselling and early screening can help catch problems before they become dangerous.

Vaccines

It is important to stay up to date with routine vaccinations, including annual flu and COVID-19 vaccines, because infections can put extra stress on your heart. Ask your doctor for advice on which vaccines are right for you.

Screening programmes

If you have a family member with Marfan syndrome, your doctor may recommend regular heart and eye screening, even if you have no symptoms. Screening for the aorta usually starts in childhood and continues throughout life. Always tell your children's doctor if Marfan syndrome runs in the family.

Complications

If left untreated

• Aortic dissection – a dangerous tear in the wall of the aorta that can be life-threatening
• Aortic rupture – a complete break in the aorta, which is a medical emergency
• Leaking heart valves (especially the aortic valve), leading to heart failure
• Severe nearsightedness or dislocation of the lens in the eye
• A collapsed lung (spontaneous pneumothorax)
• Spinal curvature that may cause back pain or breathing problems

Long-term outlook

The outlook for people with Marfan syndrome is much better today than in the past. With early diagnosis, regular imaging, medicines, and careful surgery when needed, many people live long and productive lives. The key is to stay connected with your specialist team and to follow their recommendations. Hope is very real, and research continues to improve care.
