Aortic insufficiency can be caused by:
Sometimes the cause of aortic insufficiency is unknown.
Factors that may increase your chances of developing aortic insufficiency include:

In chronic and slowly progressive aortic insufficiency, treatment may involve taking medication. Surgery is needed in severe cases.
Depending on your condition, your doctor may schedule routine physical exams and echocardiograms.
Medications cannot fix the valve, but they can be used to treat aortic insufficiency. Medication used may include:
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.
