Causes

Conditions which damage a valve can cause regurgitation. Some causes of aortic valve regurgitation are:

• Congenital heart valve disease
• Endocarditis
• Rheumatic fever
• Disease. Other rare conditions can enlarge the aortic valve and lead to regurgitation, including Marfan syndrome, a connective tissue disease
• Trauma to the aorta near the aortic valve
• Other conditions which enlarges the aortic valve (e.g Marfan syndrome)
  

Risks

Other risk factor of aortic valve regurgitation include:

• Aortic valve damage
• High blood pressure (hypertension)
• Age: In some cases, middle aged patients develop the condition due to natural deterioration of the valve.
