Structural Heart Disease

Back To Heart

Structural heart disease refers to problems or defects that weaken the heart’s structure, including its walls, valves and muscles. When these parts are misshapen or damaged, blood flow can be disrupted, leading to serious issues like stroke, heart failure or sudden cardiac arrest.

At Banner Health, our nationally recognized cardiovascular team is dedicated to diagnosing and treating structural heart disease. Our team of cardiologists, cardiac surgeons and vascular surgeons use the latest treatments and minimally invasive procedures to help patients with heart valve problems.

What is structural heart disease?

Structural heart disease changes the structure of your heart. It can affect the:

  • Heart valves
  • Heart chambers
  • Walls of the heart

Some of these conditions are congenital, meaning you are born with them. Others develop over time because of aging, infections like rheumatic fever or endocarditis or changes in the heart due to long-term high blood pressure . If not treated, structural heart disease can cause other health problems.

Types of structural heart conditions

The most diagnosed forms of structural heart disease are:

  • Heart valve disease (the most common type of structural heart disease): This happens when one or more heart valves don’t open or close the right way. Examples include mitral valve regurgitation and aortic valve stenosis.
  • Heart failure: Heart failure happens when the heart can't pump blood as well as it should. It may develop because of problems with the heart muscle, heart valves or other structural conditions.
  • Congenital heart disease: These include atrial septal defect, patent foramen ovale and ventricular septal defect.
  • Cardiomyopathy: Changes in the heart muscle where it becomes stiff and enlarged.
  • Myocarditis: When the heart muscles become inflamed.

How is structural heart disease different from coronary artery disease?

Coronary artery disease happens when the arteries that carry blood to your heart become narrowed or blocked, reducing blood flow to the heart. Structural heart disease changes the shape of the heart and how it works. It is different from arrhythmias like AFib, which are problems with the heart’s electrical system. 

What are the symptoms of structural heart disease

Symptoms depend on which part of your heart is affected. Some symptoms develop slowly and may be easy to miss at first. Others notice changes during everyday activities, such as walking up stairs or carrying groceries.

Common symptoms include:

  • Shortness of breath, especially during activity
  • Fatigue or low energy
  • Trouble exercising or being active
  • Heart murmur or irregular heartbeat (arrhythmia)
  • Swelling in the legs, ankles or feet
  • Migraines
  • Chest pain or tightening
  • Dizziness or fainting
  • Stroke or mini-stroke (TIA) without a clear cause

When should you see a cardiologist?

A team of interventional cardiologists and cardiothoracic surgeons treats structural heart disease. You might benefit from an evaluation if you:

  • Have symptoms that don’t get better with treatment
  • Were told you have a heart murmur or valve issue
  • Had a stroke with no clear cause
  • Have a known heart defect and are now an adult
  • Were told you should consider a less invasive heart procedure

How structural heart disease is diagnosed

Some cases can be diagnosed during pregnancy with a fetal echocardiogram, a test that uses sound waves to create images of the baby’s heart. In other cases, the condition may not be noticed until later in life. Your care team will perform tests to learn more about your heart and how it works. 

These tests may include:

  • Echocardiogram: An ultrasound of the heart that shows how the heart's chambers and valves are working.
  • Cardiac CT scans or MRI scans: Imaging tests that create detailed pictures of the heart and blood vessels
  • Cardiac catheterization: A thin tube, called a catheter, is inserted in an artery or vein to measure blood flow and pressure inside the heart
  • Electrocardiogram (EKG or ECG): This test measures the electrical activity of the heart and can find irregular heartbeats 
  • Transesophageal echocardiogram (TEE): This specialized ultrasound uses a thin tube placed in the esophagus to provide detailed images of the heart’s valves and walls.

How do you treat structural heart disease?

Your treatment depends on your condition, symptoms and overall health. Many structural heart problems can be fixed with less invasive procedures. Your health care provider will explain your options and help you choose what’s best for you.

Monitoring and medication

Not every condition needs immediate treatment. Some structural heart problems can be safely monitored over time. 

Your care team might also give you medicines to help with symptoms, protect your heart and help you feel better each day. These medicines can help with swelling, irregular heartbeat, high blood pressure and shortness of breath.

Lifestyle changes

A healthy lifestyle is important for managing structural heart disease and preventing it from getting worse. Your care team will advise you to:

  • Follow a heart-healthy diet that is low in salt and processed foods
  • Exercise regularly
  • Quit smoking 
  • Limit alcohol intake, keep a healthy weight
  • Manage stress
  • Attend regular follow-up appointments

Minimally invasive (transcatheter) procedures

Some people can't safely have open-heart surgery. A transcatheter procedure might be safer since it doesn’t require opening the chest.

These procedures use a small tube called a catheter. Your surgeon makes a tiny cut (incision), often in your leg, and carefully guides the catheter to your heart.

Benefits often include:

  • Smaller incisions
  • Less pain
  • Shorter hospital stays
  • Faster return to your daily life

These procedures may be used for:

  • PFO closure
  • Heart valve repair
  • Heart valve replacement
  • Closing some heart defects

Surgical treatment

Some people still need open-heart surgery to fix structural heart problems. Surgery might be the best choice for more serious conditions. The surgery involves opening the chest to reach the heart.

Surgery may involve:

  • Repairing heart valves
  • Replacing heart valves
  • Closing heart defects
  • Repairing damaged parts of the heart

What are the complications of structural heart disease?

Structural heart disease can cause serious health problems if it's not treated or watched carefully. Some of these problems include:

Frequently asked questions

What’s the difference between structural heart disease and heart disease?

Structural heart disease changes the heart's structure, like the valves or the chambers. Other types of heart disease, such as coronary artery disease, block blood flow to the heart.

Is structural heart disease serious?

It might be. Some conditions are mild but others can cause serious health problems. Getting diagnosed and treated early can help improve outcomes.

Can structural heart disease be treated without surgery?

Yes. Many conditions can now be treated with minimally invasive procedures that use a small incision rather than open-heart surgery. 

What is a PFO and why does it matter?

A PFO, or patent foramen ovale, is a small opening in the heart that fails to close after birth. Most people don’t know they have one. In some people, it may increase the risk of stroke.
