Is there a problem with your aorta? Let's talk about Aortopathy with Nirogi Lanka!

Have you ever wondered what the largest and most vital blood vessel in your body is? It is your aorta—the main superhighway of your circulatory system. This major artery runs from your heart all the way down to your abdomen, serving as the essential conduit that delivers oxygen-rich, fresh blood to your entire body. Because it is so critical, any issue affecting your aorta can have serious implications for your overall health. At Nirogi Lanka, we refer to this group of conditions that affect the aorta as aortopathy.

What is Aortopathy? Let’s break it down simply.

Simply put, aortopathy refers to a group of conditions that weaken or damage the walls of your aorta. Think of it this way: every time your heart beats, it pumps blood directly into this large artery. To handle that pressure, your aortic walls must be strong and resilient. However, if these walls become weak, they can bulge, rupture, or tear (dissect), which can be life-threatening. The specific type of aortopathy you have determines how your aorta is affected.

What are the main types of Aortopathy?

There are several types of aortopathy. Let’s discuss the most common ones.

Abdominal Aortic Aneurysm (AAA)

This occurs when a section of the aorta passing through your abdomen weakens and bulges like a balloon. We call this an aneurysm. This condition is most common in individuals over 65, those who smoke, or those with other cardiovascular risk factors. The danger with an AAA is that it can suddenly rupture, causing life-threatening internal bleeding.

Thoracic Aortic Aneurysm (TAA)

This involves a weakening or bulging in the part of the aorta that runs through your chest. While (TAA) is less common than (AAA), it often has a strong genetic component, meaning it can run in families. Like (AAA), the primary risk with (TAA) is a life-threatening rupture.

The Danger of Aortic Dissection

This is a serious emergency. An aortic dissection happens when the inner layer of your aortic wall tears. This usually occurs in an area where the wall is already weak, sometimes where an aneurysm exists, though it can occur without one. There are two main types: Type A dissection, which involves a tear in the part of the aorta closest to the heart (before the arch), and Type B dissection, which occurs after the arch, in the chest or abdomen. Aortic dissection is a medical emergency requiring immediate diagnosis and treatment.

Understanding Familial Aortopathy

Familial aortopathy refers to aortic diseases that have a genetic (hereditary) link. Individuals with this condition have specific gene variants that increase their susceptibility to aortic diseases. This often affects the thoracic aorta, particularly the aortic root or the ascending aorta.

It is generally categorized into two types:

What is Syndromic Aortopathy?

Often called (Syndromic heritable thoracic aortic disease), this occurs when you have a genetic syndrome that affects the aorta alongside other physical features or conditions. Some syndromes linked to aortic disease include:

• Loeys-Dietz syndrome
• Marfan syndrome
• Turner syndrome
• Vascular Ehlers-Danlos syndrome

Understanding Non-syndromic Aortopathy

Known as (Non-syndromic heritable thoracic aortic disease), this happens when you do not have a specific named syndrome, but you carry gene variants that increase your risk of aortic disease. Scientists have identified over 50 genes associated with these conditions. Some of the most significant include:

• ACTA2 (the most common)
• FOXE3
• LOX
• MYH11
• MYLK

Remember, if a family member has had an aortic aneurysm or dissection, talk to your doctor about genetic testing. If you are diagnosed with an aortic condition, your relatives may also need genetic testing to determine if they are at risk.

What is Bicuspid Aortopathy?

This is often referred to as (Bicuspid valve-associated aortopathy). It means that in addition to an aortic condition, you have a congenital heart condition called a Bicuspid Aortic Valve (BAV). BAV is the most common congenital heart defect, affecting approximately 1 in 50 people.

Your aortic valve acts as a gatekeeper, controlling blood flow from your heart's main pumping chamber (left ventricle) into the aorta. A healthy aortic valve typically has three leaflets; a bicuspid valve only has two. While many people with BAV may be asymptomatic for years, it can lead to complications over time.

If you have bicuspid aortopathy, your aortic valve has only two leaflets, and your aorta is often wider than normal (dilatation). In (BAV) patients, this dilation usually occurs in the aortic root or the ascending aorta—the sections closest to your heart.

Complications of Bicuspid Aortopathy

Mild dilation may not cause immediate issues. However, if the aorta widens significantly, it can develop into an aneurysm. This puts excessive pressure on the aortic walls, increasing the risk of rupture or dissection. Individuals with bicuspid aortopathy are nearly nine times more likely to experience an aortic dissection than those without the condition.

How common is Aortopathy?

The prevalence depends on the specific condition. Abdominal Aortic Aneurysm (AAA) is the most frequent form of aortopathy. In the United States alone, approximately 200,000 cases of AAA are diagnosed annually. Globally, it is estimated that about 47,000 people lose their lives each year due to various types of aortopathy.

What are the symptoms of Aortopathy? Do not ignore these!

Most of the time, aortopathy is asymptomatic, which is what makes it so dangerous. This is why regular medical check-ups are vital if you have underlying risk factors.

As an aortic aneurysm nears the point of rupture, you may notice some warning signs:

• A feeling of fullness in your abdomen after eating only a little.
• Persistent pain in your back, buttocks, groin, legs, or abdomen.
• A pulsing or throbbing sensation near your navel, similar to a heartbeat.
• Shortness of breath.

A ruptured aortic aneurysm and aortic dissection are life-threatening medical emergencies! If you experience the following, call 911 or your local emergency services immediately, or go to the nearest hospital emergency department:

• Sudden, severe abdominal pain.
• Sudden, intense, sharp pain in your chest or upper back. This may feel like tearing, stabbing, or ripping.
• Clammy skin or excessive sweating.
• Confusion.
• Dizziness or fainting.
• Rapid heart rate.
• Nausea and vomiting.
• Difficulty breathing.
• Difficulty speaking.
• Sudden vision loss.
• Weakness or paralysis on one side of the body.

What causes Aortopathy?

Aortopathy can stem from various causes, some present from birth (congenital) and others developing later in life.

• Genetics: Genetic syndromes and gene variants can predispose you to aortic disease. Familial Aortopathy is often inherited in an `autosomal dominant` pattern, meaning if one parent carries the gene, there is a 50% chance of passing it to their children.
• Congenital heart disease: These are often associated with aortopathy. Examples include `Bicuspid aortic valve`, `Coarctation of the aorta`, `Pulmonary atresia with ventricular septal defect (VSD)`, `Tetralogy of Fallot`, `d-Transposition of the great arteries`, and `Truncus arteriosus`. Some surgical repairs, such as `Arterial switch (ASO)`, `Atrial baffle (Mustard/Senning)`, or the `staged Norwood, Glenn, and Fontan surgeries`, may also be linked to later development of aortopathy.
• Atherosclerosis:The buildup of plaque in your arteries, causing them to narrow, is a leading cause of aortopathy that develops later in life.

Who is at higher risk for Aortopathy?

Several risk factors contribute to the development of aortopathy:

• Smoking and tobacco use: This is a major threat. The vast majority of aortic aneurysms occur in individuals who currently smoke or have a history of smoking.
• High blood pressure (Hypertension): Over time, this can weaken the walls of your aorta.
• Age: The risk of developing an aortic aneurysm increases significantly after age 65.
• Family history: If a biological family member has had an aneurysm or dissection, your risk is inherently higher.
• High cholesterol or triglycerides: Elevated lipid levels increase the potential for plaque buildup in your arteries.
• Autoimmune disease: Conditions like `Giant cell arteritis` and `Takayasu arteritis` can cause inflammation, weakening the aortic walls.
• Infection: Rarely, infections like `syphilis` or bacterial infections in the aortic wall can cause structural weakness.

How is Aortopathy diagnosed?

Because these conditions often lack warning signs until a serious complication occurs, we rely on proactive screening if you have known risk factors. Your doctor at Nirogi Lanka will evaluate your aortic health if they suspect an issue.

Common diagnostic methods include:

• Physical exam: Your doctor will conduct a comprehensive health assessment, evaluate your cardiovascular risk factors, and review your medical history, lifestyle habits, and family history.
• Genetic testing: Your doctor may recommend genetic testing to check for specific mutations associated with aortic disease.
• Imaging tests: To assess the size and health of your aorta, doctors use specialized imaging. These tests measure the aortic diameter to determine if it has widened beyond normal limits.

How is Aortopathy diagnosed?

• Computed tomography (CT) scan
• Magnetic resonance imaging (MRI)
• Transthoracic echocardiogram (TTE) (a non-invasive heart ultrasound)
• Transesophageal echocardiogram (TEE) (an ultrasound performed via the esophagus)
• Abdominal ultrasound

Every diagnostic test has its own unique benefits and potential limitations. Your doctor will explain which tests are necessary for your specific situation and why. They may use one or more of these tests to monitor your aorta over time. You might be required to undergo these imaging tests at regular intervals (for example, once a year). The frequency of these check-ups depends entirely on your personal risk factors and the current state of your aorta's health.

What treatments are available for Aortopathy?

Your treatment plan is tailored to your specific condition and the level of risk for complications. At Nirogi Lanka, your doctor will personalize a care plan that suits your needs, which may include lifestyle adjustments, medications, specialized procedures, or surgery.

Let's start with lifestyle adjustments!

Certain lifestyle changes can help slow the progression of aortic disease and lower the risk of an aneurysm rupture. If you have been diagnosed with an aortic condition, it is vital to:

• Avoid alcohol consumption.
• Stop smoking and abstain from all tobacco products.
• Adopt a heart-healthy diet.
• Engage in regular exercise (as guided by your doctor).
• Maintain a healthy weight.
• Manage heart disease risk factors like high blood pressure and high cholesterol.

Medications can play a crucial role

Your doctor may prescribe medication to help lower your blood pressure. By reducing blood pressure, you decrease the stress placed on your arterial walls, which lowers the risk of an aortic aneurysm rupturing or experiencing a dissection. Common medications include:

• Angiotensin-converting enzyme (ACE) inhibitors
• Angiotensin receptor blockers (ARBs)
• Beta-blockers
• Calcium channel blockers
• Diuretics (water pills)

Surgery and medical procedures

Some individuals with aortopathy may require a medical procedure or surgery. These include:

• Aneurysm surgery (traditional open surgery)
• Aortic root replacement surgery
• Endovascular aneurysm repair (EVAR) – a minimally invasive procedure using a small incision and a catheter.
• Thoracic endovascular aneurysm repair (TEVAR) – a similar minimally invasive technique for the chest aorta.

How can you reduce your risk of Aortopathy?

Adopting a heart-healthy lifestyle is your best defense against developing aortopathy. Here are some tips:

• Avoid harmful substances: Tobacco, drugs, and excessive alcohol are detrimental to your heart and blood vessels. We strongly recommend quitting tobacco and drugs entirely. Regarding alcohol, aim to stay within recommended limits—generally no more than one drink per day for women and two for men.
• Eat heart-healthy foods: Focus on meals low in saturated fat, trans fat, sodium, and added sugar. Limit refined carbohydrates like white bread and opt for whole grains instead. Stay mindful of how your nutrition impacts your cholesterol levels.
• Stay active: Exercise looks different for everyone. Find an activity you enjoy and follow your doctor’s advice on safe intensity levels. Generally, aim for 150 minutes of moderate activity per week, such as brisk walking, cycling, or swimming.
• Manage stress:While easier said than done, learning stress-management techniques is essential. Share these challenges with your support system of friends and family.

What is the outlook if you have Aortopathy?

Your doctor is the best person to discuss your specific prognosis. They will consider several factors, including:

• Your specific diagnosis.
• The rate of disease progression.
• Your age and gender.
• Your cardiovascular risk factors.
• Your family medical history.
• Your overall medical history.

Please feel empowered to have an open conversation with your healthcare provider about what you can expect moving forward.

How should I take care of myself if I have Aortopathy?

Your doctor will provide specific self-care guidelines. Follow these instructions carefully, and never hesitate to reach out with questions. You may be advised to:

• Avoid strenuous exercise or contact sports.
• Limit or eliminate alcohol consumption.
• Make dietary modifications.
• Stop all tobacco use.
• Take your prescribed medications consistently.

Pregnancy and Aortopathy

If you have an aortopathy, pregnancy can pose significant risks. Before planning to conceive, please speak with your doctor to determine if it is safe for you. To minimize the risk of complications, you may require specialized prenatal care, such as more frequent imaging tests. Your doctor may also need to adjust your medications to ensure you avoid any drugs that are unsafe during pregnancy.

When should you see your doctor?

Make sure to attend your annual medical examinations and keep every follow-up appointment. Your doctor will advise you on the necessary frequency of your check-ups.

If you were diagnosed with a congenital heart condition as a child, you likely had a pediatric cardiologist monitoring your health. However, after turning 18, you may not have established care with a new specialist. Research shows that many people struggle with the transition from pediatric to adult medical care. If you were treated for a congenital heart condition in your youth, it is essential to continue working with an adult cardiologist. This remains true even if you feel completely healthy.Your cardiologist will provide guidance on the risks of aortopathy and other conditions as you age.

Important Take-Home Message

Aortopathy is a serious condition that can be life-threatening if left undiagnosed and untreated. If anyone in your family has had an aortic aneurysm or dissection, please talk to your doctor to understand your personal risk. Some individuals are at higher risk due to genetic conditions, congenital heart defects, or lifestyle factors like smoking. Maintaining a heart-healthy lifestyle can help lower your risk of aortopathy and strengthen your overall body. Take care of your heart—it is the beat of your life!
