| Risk Factors
The aorta is the main artery carrying oxygen-rich blood from the heart to the body. After each heart beat, the valve closes tightly to prevent blood from flowing backwards into the heart. Aortic insufficiency occurs when the aortic valve does not close tightly enough.
There are two types of aortic insufficiency:
Acute aortic insufficiency
—symptoms develop rapidly, and in severe cases, immediate surgery may be needed
Chronic aortic insufficiency
—symptoms develop over the course of many months or years

Aortic insufficiency can be caused by:
Sometimes the cause of aortic insufficiency is unknown.
Factors that increase your chances of developing aortic insufficiency include:
- Family history of aortic insufficiency
- High blood pressure
- Use of drugs such as weight loss and appetite suppressant medicines
Symptoms of aortic insufficiency include:
- Shortness of breath with activity
- Exercise intolerance
- Chest pain
- Heart palpitations
- Irregular heartbeat
- Difficulty breathing when lying flat
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Images may be taken of your heart. This can be done with:
Treatment options depend on the severity and history of the valve leakage. It also depends on its effects on the heart’s size and function. Talk with your doctor about the best treatment plan for you.
In chronic and slowly progressive aortic insufficiency, treatment may involve taking medicine. Surgery is needed in severe cases.
Depending on your condition, your doctor may schedule routine physical exams and echocardiograms.
Medicines cannot fix the valve, but they can be used to treat aortic insufficiency. Medicines used may include:
- Diuretics—to treat high blood pressure and rid the body of excess fluids
- Calcium channel blockers—to reduce leaking and, in some cases, delay the need for surgery
- High blood pressure medicines
- Antibiotics used before dental and surgical procedures to prevent infection
If the condition is rapidly declining, surgery is needed.
There are several open heart surgeries that can fix leaking valves. The type chosen will depend on the valve and the knowledge of the surgeon.
In most cases, this condition cannot be prevented. Ask your doctor if you should take an antibiotic before dental and other procedures. This can help to prevent infection.
