Doctors call this group of conditions structural heart disease. Some people are born with these heart differences. This others develop them as they grow older. Without proper care and medical follow-up, these issues can lead to more serious health challenges over time.

Evidence-based clinical answers to common patient questions

What is structural heart disease?

It is a general term for any problem with the physical parts of your heart. This includes heart valves, muscle walls, chambers, or congenital defects present from birth.

Can structural heart disease be cured?

Many cases can be successfully repaired or managed with modern heart surgery, minimally invasive procedures, or medicines. Your doctor will tailor treatment to your specific heart condition.

What are the most common symptoms?

Common signs include shortness of breath during daily activities, unusual tiredness, chest discomfort, dizziness, and swelling in your ankles or feet.

How do doctors test for this condition?

Doctors commonly use an echocardiogram (sound wave picture of the heart) and an ECG (heart electrical test) to check your heart structure and function.

Can I exercise if I have a structural heart problem?

Many people can do light or moderate exercise safely. Always ask your cardiologist what physical activities are safe and appropriate for your specific heart health.

  1. Structural heart disease affects the shape, walls, valves, or muscles of your heart.
  2. It includes heart valve problems, weak heart muscles, and conditions present from birth.
  3. Common signs include shortness of breath, tiredness, chest discomfort, and swollen feet.
  4. Doctors use simple tests like an echocardiogram to check your heart structure.
  5. Treatments range from regular doctor visits and simple medicines to advanced heart procedures.
  6. Heart valve disease: Your heart has four special doors called valves. These valves make sure your blood flows in only one direction. If a valve gets too narrow, doctors call it stenosis. If a valve does not close tightly and lets blood leak backward, it is called regurgitation.
  7. Cardiomyopathy (Heart muscle disease): This happens when your heart muscle gets weak, thick, or stretched out. When this occurs, your heart cannot pump blood properly. Think of it like a water pump that loses its power and cannot push water forward.
  8. Congenital heart disease: These are heart problems that babies are born with. Some babies are born with a small hole in their heart or a faulty valve. These are structural issues present right from birth.
  9. Family history: If someone in your close family has a heart condition, you might have a higher chance of getting one too.
  10. Conditions during pregnancy: Sometimes, things that happen while a baby is growing inside the mother can cause congenital heart issues. Examples include:.
  11. Exposure to harmful industrial chemicals during pregnancy.
  12. Getting an infection like rubella during the first three months of pregnancy.
  13. Taking certain medicines without doctor approval or drinking alcohol.
  14. Catching specific viral infections.
  15. Getting older: As we age, calcium can build up in our heart valves and other areas. This can cause heart problems later in life. In fact, more than ten percent of adults over age seventy-five have some form of structural heart issue.
  16. Conditions from birth: Changes in your body genes or DNA can create unusual heart shapes while you grow.
  17. Later-life causes:.
  18. Growing older, which lets calcium build up on your heart valves.
  19. Using alcohol or street drugs.
  20. Swelling or stretching of your main large artery, known as an aortic aneurysm.
  21. Immune system disorders, such as lupus or rheumatic fever.
  22. Heart attacks or past heart damage.
  23. Rare diseases that harm the heart, such as amyloidosis, hemochromatosis, or sarcoidosis.
  24. Infections inside the heart lining, known as endocarditis.
  25. Gland and hormone disorders, such as diabetes and thyroid disease.
  26. High blood pressure.
  27. Exposure to high levels of radiation.

  37. Shortness of breath during normal daily tasks.
  38. Swelling in your belly, ankles, or feet.
  39. Cardiac catheterization: The doctor guides a tiny tube through a blood vessel in your groin or arm up to your heart to measure pressures and check your blood vessels.
  40. Coronary angiogram: Done during a catheterization, this test uses a safe dye and X-rays to see how blood flows through your heart arteries and valves.
  41. Echocardiogram (Echo): This painless test uses sound waves to make moving pictures of your heart chambers and valves. It shows how well your heart pumps blood.
  42. Electrocardiogram (ECG or EKG): This test measures the electrical signals of your heart using small sticky patches placed on your chest.
  43. Exercise stress test: You walk or run on a treadmill while the doctor watches how your heart handles physical activity.
  44. Holter monitor: You wear a small portable machine for twenty-four to forty-eight hours while doing normal daily activities to record your heart rhythm.
  45. Other imaging tests: Chest X-rays, CT scans, or cardiac MRI scans give doctors clear pictures of structural problems inside your chest.
  46. Medicines: Drugs can help control your symptoms, make your heart pump better, or stop dangerous blood clots from forming.
  47. Minimally invasive heart procedures: Instead of a large cut, doctors make tiny punctures to guide special tools into your heart to repair or replace a damaged valve.
  48. Open-heart surgery: A surgeon opens the chest to reach the heart directly. They can replace valves or perform a heart transplant if needed.
  49. Talk with your doctor about any long-term health issues like diabetes or epilepsy and check your medicines.
