To diagnose aortic valve disease, your doctor may review your signs and symptoms, discuss your medical history, and conduct a physical examination. Your doctor may listen to your heart with a stethoscope to determine if you have a heart murmur that may indicate an aortic valve condition. A doctor trained in heart disease (cardiologist) may evaluate you.
Your doctor may order several tests to diagnose your condition, including:
Echocardiogram. This test uses sound waves to provide video images of your heart in motion. During this test, specialists hold a wandlike device (transducer) on your chest. Doctors may use this test to evaluate your heart chambers, the aortic valve and the blood flow through your heart.
This test can help doctors closely look at the condition of the aortic valve, and the cause and severity of your condition. It can also help doctors determine if you have additional heart valve conditions. Doctors may also use a 3D echocardiogram.
Doctors may conduct another type of echocardiogram called a transesophageal echocardiogram to get a closer look at the aortic valve. In this test, a small transducer attached to the end of a tube is inserted down the tube leading from your mouth to your stomach (esophagus).
- Electrocardiogram (ECG). In this test, wires (electrodes) attached to pads on your skin measure the electrical activity of your heart. An ECG can detect enlarged chambers of your heart, heart disease and abnormal heart rhythms.
- Chest X-ray. A chest X-ray can help your doctor determine whether the heart is enlarged, which can indicate certain types of aortic valve disease. It can also show whether you have an enlarged blood vessel (aorta) leading from the heart or any calcium buildup on the aortic valve. A chest X-ray can also help doctors determine the condition of your lungs.
- Cardiac computerized tomography (CT) scan. A cardiac CT scan uses a series of X-rays to create detailed images of your heart and heart valves. Doctors may use this imaging technique to measure the size of your aorta and look at your aortic valve more closely.
- Cardiac MRI. A cardiac MRI uses magnetic fields and radio waves to create detailed images of your heart. This test may be used to determine the severity of your condition and evaluate the size of the aorta.
- Exercise tests or stress tests. Exercise tests help doctors see whether you have signs and symptoms of aortic valve disease during physical activity, and these tests can help determine the severity of your condition. If you are unable to exercise, medications that have similar effects as exercise on your heart may be used.
Cardiac catheterization. This test isn't often used to diagnose aortic valve disease, but it may be used if other tests aren't able to diagnose the condition or to determine its severity.
In this procedure, a doctor threads a thin tube (catheter) through a blood vessel in your arm or groin to an artery in your heart and injects dye through the catheter to make the artery visible on an X-ray. This provides your doctor with a detailed picture of your heart arteries and how your heart functions. It can also measure the pressure inside the heart chambers to help in the evaluation of aortic valve disease.
Treatment for aortic valve disease depends on the severity of your condition, whether or not you're experiencing signs and symptoms, and if your condition is getting worse.
If your aortic valve disease is mild or moderate or you aren't experiencing symptoms, your doctor may monitor your condition with regular follow-up appointments. Your doctor may recommend you make healthy lifestyle changes and take medications to treat symptoms or reduce the risk of complications.
You may eventually need surgery or another procedure to repair or replace the diseased aortic valve. In some cases, your doctor may recommend surgery even if you aren't experiencing symptoms. If you're having another heart surgery, doctors may perform aortic valve surgery at the same time.
If you have aortic valve disease, consider being evaluated and treated at a medical center with a multidisciplinary team of cardiologists and other doctors and medical staff trained and experienced in evaluating and treating heart valve disease. This team can work closely with you to determine the most appropriate treatment for your condition.
Surgery to repair or replace an aortic valve is usually performed through a cut (incision) in the chest. In some cases, doctors may perform minimally invasive heart surgery, which involves the use of smaller incisions than those used in open-heart surgery.
Surgery options include:
Aortic valve repair
To repair an aortic valve, surgeons may conduct several different types of repair, including separating valve flaps (cusps) that have fused, removing excess valve tissue so that the cusps can close tightly or patching holes in a valve.
Doctors may conduct a procedure using a long, thin tube (catheter) to open up a valve with a narrowed opening (aortic valve stenosis). In this procedure, called balloon valvuloplasty, a doctor inserts a catheter with a balloon on the tip into an artery in your groin and guides it to the aortic valve. A doctor then inflates the balloon, which expands the opening of the valve. The balloon is then deflated, and the catheter and balloon are removed.
The procedure can treat aortic valve stenosis in infants and children. However, the valve tends to narrow again in adults who've had the procedure, so it's usually only performed in adults who are too ill for surgery or who are waiting for a valve replacement, as they typically need additional procedures to treat the narrowed valve over time.
Doctors may also use a catheter procedure to insert a plug or device to repair a leak around a replaced aortic valve.
Aortic valve replacement
Biological valve replacement
In a biological valve replacement, a biological or tissue valve replaces the damaged valve.
Aortic valve replacement is often needed to treat aortic valve disease. In aortic valve replacement, your surgeon removes the damaged valve and replaces it with a mechanical valve or a valve made from cow, pig or human heart tissue (biological tissue valve). Another type of biological tissue valve replacement that uses your own pulmonary valve is sometimes possible.
Mechanical valve replacement
In a mechanical valve replacement, a mechanical valve replaces the damaged valve.
Biological tissue valves degenerate over time and may eventually need to be replaced. People with mechanical valves will need to take blood-thinning medications for life to prevent blood clots. Your doctor will discuss with you the benefits and risks of each type of valve and discuss which valve may be appropriate for you.
Transcatheter aortic valve replacement (TAVR)
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic valve stenosis). In this procedure, doctors insert a catheter in your leg or chest and guide it to your heart. A replacement valve is inserted through the catheter and guided to your heart. A balloon is expanded to press the valve into place. Some TAVR valves are self-expanding.
Doctors may perform a less invasive procedure called transcatheter aortic valve replacement (TAVR) to replace a narrowed aortic valve. TAVR may be an option for people who are considered to be at increased risk of complications from surgical aortic valve replacement.
In TAVR, doctors insert a catheter in your leg or chest and guide it to your heart. A replacement valve is then inserted through the catheter and guided to your heart. A balloon may expand the valve, or some valves can self-expand. When the valve is implanted, doctors remove the catheter from your blood vessel.
Doctors may also conduct a catheter procedure to insert a replacement valve into a failing biological tissue valve that is no longer working properly. Other catheter procedures to repair or replace aortic valves continue to be researched.

Lifestyle and home remedies
You'll have regular follow-up appointments with your doctor to monitor your condition.
Your doctor may suggest you incorporate several heart-healthy lifestyle changes into your life, including:
- Eating a heart-healthy diet. Eat a variety of fruits and vegetables, low-fat or fat-free dairy products, poultry, fish, and whole grains. Avoid saturated and trans fat, and excess salt and sugar.
- Maintaining a healthy weight. Aim to keep a healthy weight. If you're overweight or obese, your doctor may recommend that you lose weight.
- Getting regular physical activity. Aim to include about 30 minutes of physical activity, such as brisk walks, into your daily fitness routine.
- Managing stress. Find ways to help manage your stress, such as through relaxation activities, meditation, physical activity, and spending time with family and friends.
- Avoiding tobacco. If you smoke, quit. Ask your doctor about resources to help you quit smoking. Joining a support group may be helpful.
For women with aortic valve disease, it's important to talk with your doctor before you become pregnant. Your doctor can discuss with you which medications you can safely take, and whether you may need a procedure to treat your valve condition prior to pregnancy.
You'll likely require close monitoring by your doctor during pregnancy. Doctors may recommend that women with severe valve conditions avoid pregnancy to avoid the risk of complications.
Coping and support
If you have aortic valve disease, here are some steps that may help you cope:
- Take medications as prescribed. Take your medications as directed by your doctor.
- Get support. Having support from your family and friends can help you cope with your condition. Ask your doctor about support groups that may be helpful.
- Stay active. Aim to stay physically active. Your doctor may give you recommendations about how much and what type of exercise is appropriate for you.
Preparing for your appointment
If you think you have aortic valve disease, make an appointment to see your doctor. Here's some information to help you prepare for your appointment.
- Be aware of pre-appointment restrictions. When you make the appointment, ask if there's anything you need to do beforehand.
- Write down your symptoms, including any that seem unrelated to heart valve disease.
- Write down key personal information, including a family history of heart disease, and any major stresses or recent life changes.
- Make a list of all medications, vitamins and supplements you take.
- Take a family member or friend along, if possible. Someone who accompanies you can help you remember information you receive.
- Be prepared to discuss your diet and exercise habits. If you don't already eat well and exercise, be ready to talk to your doctor about challenges you might face in getting started.
- Write down questions to ask your doctor.
For aortic valve disease, some basic questions to ask your doctor include:
- What is likely causing my symptoms or condition?
- What are other possible causes for my symptoms or condition?
- What tests will I need?
- What's the best treatment?
- What are the alternatives to the primary approach you're suggesting?
- I have other health conditions. How can I best manage them together?
- Are there restrictions I need to follow?
- Should I see a specialist?
- If I need surgery, which surgeon do you recommend for heart valve surgery?
- Is there a generic alternative to the medicine you're prescribing?
- Are there brochures or other printed material I can take with me? What websites do you recommend?
Don't hesitate to ask other questions you have.
What to expect from your doctor
