Aortic Regurgitation

Aortic regurgitation, also known as aortic valve regurgitation or aortic insufficiency, is a heart condition that occurs when the aortic valve in your heart doesn’t close properly. This allows blood to flow backward into the heart, causing various problems. In this article, we will provide a straightforward explanation of aortic regurgitation, its types, causes, symptoms, diagnostic tests, treatment options, medications, and surgical procedures.

Aortic regurgitation happens when the aortic valve, which separates the left ventricle from the aorta (the main artery), doesn’t close tightly. This allows blood to leak back into the heart instead of flowing forward into the body.

Types of Aortic Regurgitation:

There are two primary types of aortic regurgitation:

1. Acute Aortic Regurgitation: It develops suddenly and requires immediate medical attention.
2. Chronic Aortic Regurgitation: This type progresses slowly over time and may not show symptoms until later stages.

Causes of Aortic Regurgitation

1. Bicuspid Aortic Valve: A congenital condition where the aortic valve has two cusps instead of the usual three.
2. Rheumatic Fever: A bacterial infection that can damage the aortic valve.
3. Aortic Aneurysm: A bulge in the aorta can affect the valve’s function.
4. Endocarditis: Infection of the inner lining of the heart, including the aortic valve.
5. Aging: Wear and tear on the valve can lead to regurgitation over time.
6. Connective Tissue Disorders: Conditions like Marfan syndrome can affect the aortic valve.
7. High Blood Pressure: Chronic hypertension can strain the valve.
8. Aortic Valve Stenosis: Narrowing of the aortic valve can lead to regurgitation.
9. Trauma: Injuries to the chest or heart can damage the valve.
10. Aortic Valve Prolapse: The valve’s leaflets bulge backward.
11. Syphilis: A rare infection that can damage the aortic valve.
12. Radiation Therapy: Previous chest radiation treatment may cause valve problems.
13. Ankylosing Spondylitis: An inflammatory condition that can affect the aorta.
14. Aortic Dissection: A tear in the aorta can lead to regurgitation.
15. Congenital Heart Defects: Some people are born with valve abnormalities.
16. Systemic Lupus Erythematosus (SLE): An autoimmune disease that can affect the heart.
17. Certain Medications: Long-term use of certain drugs may lead to valve issues.
18. Aortic Valve Tumors: Rare tumors on the valve can cause regurgitation.
19. Other Heart Conditions: Conditions like dilated cardiomyopathy can impact the valve.
20. Idiopathic: In some cases, the exact cause is unknown.
