What is aortic regurgitation? Aortic regurgitation is when blood flows backward through the aortic valve because it does not close properly. The aortic valve is between the left ventricle and the aorta. The left ventricle is the lower left chamber of your heart. The aorta is a blood vessel that pumps blood to your body. The aortic valve opens and closes to direct blood flow through your heart.
What causes aortic regurgitation?
Congenital heart defect: Some people are born with a damaged aortic valve.
Age: The aortic valve can get weaker and wear out as you age.
Bacterial endocarditis: This is an infection of the lining of the heart. The aortic valve may also be infected.
Rheumatic fever: This is fever and inflammation of your joints. It can develop after you have a strep throat infection. Rheumatic fever can cause scarring of your aortic valve. The valve may not work properly. This can lead to regurgitation.
Medical conditions: Syphilis, ankylosing spondylitis, and Marfan syndrome can damage the aortic valve.
Trauma: A chest injury or tear in the aorta can cause aortic regurgitation.
Medicines: Certain medicines, such as diet pills, can cause aortic regurgitation.
What are the signs and symptoms of aortic regurgitation?
- Severe tiredness
- Shortness of breath during activity or when you lie down
- Chest pain or tightness
- Dizziness or feeling faint
- Fast, jumpy, or fluttery heartbeat
- Swollen feet or ankles
How is aortic regurgitation diagnosed? Your caregiver will ask about your signs and symptoms and listen to your heart. You may need any of the following tests:
An echocardiogram is a type of ultrasound. Sound waves are used to show the structure and function of your heart.
Chest x-ray: This is used to check the size of your heart and look for fluid around your heart and lungs.
EKG: This test records the electrical activity of your heart. It is used to check for abnormal heart rhythm caused by aortic regurgitation.
Transesophageal echocardiogram (TEE): This test will show regurgitation, enlarged heart, or an infection. You will be given medicine to relax you during a TEE. Caregivers will put a tube in your mouth that is moved down into your esophagus. The tube has a small ultrasound sensor on the end. Since your esophagus is right next to your heart, your caregiver can see your heart clearly.
Exercise stress test: This test helps caregivers see the changes that take place in your heart during exercise. It checks for blockages in the arteries of your heart. An EKG is done while you ride an exercise bike or walk on a treadmill. Caregivers will ask you how you are feeling during the test. They want to know if you have chest pain or trouble breathing.
Cardiac catheterization: This procedure is done to find and treat regurgitation. A thin, bendable tube is inserted into your arm, neck, or groin and moved into your heart. An x-ray may be used to guide the tube to the right place. Dye may be put into your vein so the pictures show up better on a monitor. Tell the caregiver if you have ever had an allergic reaction to contrast dye.
How is aortic regurgitation treated?
Diuretics: This medicine is given to remove extra fluid that has collected in your heart, lungs, or legs. They are often called water pills. You may urinate more often when you take this medicine.
Blood pressure medicine: This will help lower your blood pressure and keep your heart from working too hard.
Repair: Caregivers make an incision in your chest to repair your aortic valve. This helps improve the blood flow through your heart.
Replacement: Caregivers make an incision in your chest to replace your damaged aortic valve. Part or all of your aortic valve is removed, and a new valve is secured in place. The new valve may be from a donor (another person or animal), or may be a manmade valve.
What are the risks of aortic regurgitation? You may develop an infection in your heart. This infection can damage your valves and heart muscle. Your heart may not be able to pump enough blood to your body. You heart can swell and weaken. This can lead to heart failure, which is life-threatening.
How can I manage my symptoms?
Eat a variety of healthy foods: Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. You may need to limit the amount of salt you eat. Ask if you need to be on a special diet.
Exercise: This will improve your heart health. Ask your caregiver about the best exercise plan for you.
Maintain a healthy weight: Ask your caregiver how much you should weigh. Ask him to help you create a weight loss plan if you are overweight.
