Aortic insufficiency is a heart valve disease in which the aortic valve does not close tightly. This leads to the backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (a chamber of the heart).
Aortic insufficiency can result from any condition that keeps the aortic valve from closing all the way. A small amount of blood comes back each time the heart beats.
The condition causes widening (dilation) of the left lower chamber of the heart. Larger amounts of blood leave the heart with each squeeze or contraction. This leads to a strong and forceful pulse (bounding pulse). Over time, the heart becomes less able to pump blood to the body.
In the past, rheumatic fever was the main cause of aortic insufficiency. Now that antibiotics are used to treat rheumatic fever, other causes are more commonly seen.
Causes of aortic insufficiency may include:
Aortic insufficiency is most common in men between the ages of 30 and 60.
Aortic insufficiency often has no symptoms for many years. Symptoms may occur slowly or suddenly.
Signs may include:
Aortic insufficiency may be seen on:
A chest X-ray may show swelling of the left lower heart chamber. Lab tests cannot diagnose aortic insufficiency, but they may be used to rule out other disorders or causes.
If there are no symptoms or if symptoms are mild, you may only need to get an echocardiogram from time to time and be monitored by a healthcare provider.
If your blood pressure is high, then treatment with certain blood pressure medications may help slow the worsening of aortic regurgitation.
ACE inhibitor drugs and diuretics (water pills) may be prescribed for more moderate or severe symptoms.
In the past, most patients with heart valve problems were given antibiotics before dental work or an invasive procedure, such as colonoscopy. The antibiotics were given to prevent an infection of the damaged heart. However, antibiotics are now used much less often before dental work and other procedures.
You may need to limit activity that requires more work from your heart. Talk to your healthcare provider.
Surgery to repair or replace the aortic valve corrects aortic insufficiency. The decision to have aortic valve replacement depends on your symptoms and the condition and function of your heart.
You may also need surgery to repair the aorta if it is widened.
