Aortic valve regurgitation or aortic regurgitation is a condition that occurs when your heart's aortic valve doesn't close tightly. From the aorta, oxygen-rich blood flows into the branching arteries and straight through the body to feed the cells. The body doesn't receive sufficient blood, so the heart must work harder to make up for it (compensation) Regurgitation means the valve doesn't close properly, and blood can leak backward straight through it. See an illustration of aortic valve regurgitation. This commonly doesn't cause any symptoms or problems.
This topic focuses on the more serious cases of aortic valve regurgitation where large amounts of blood flow back over the aortic valve into the left ventricle. Aortic regurgitation can range from mild to severe. Some habitancy may have no symptoms for years. But as the condition worsens, symptoms will appear. Eventually, despite this compensation, the heart may be unable to meet the body's need for blood, prominent to heart failure, with fluid accumulation in the lungs.
Causes of Aortic Regurgitation
The base Causes of Aortic Regurgitation :
Hypertension
Congenital bicuspid aortic valve (person is born with only two aortic valve leaflets, instead of the general three)
Aortic Dissection
Syphilis
Ankylosing Spondylitis
Aortic Dissection
Marfan's Syndrome
Rheumatic heart disease (caused by untreated "strep throat" in childhood)
Symptoms of Aortic Regurgitation
Some Symptoms of Aortic Regurgitation:
Chest pain.
Fatigue.
Shortness of breath while resting prone.
Usually none until age 40-50.
Swollen ankles and feet.
Shortness of breath on exertion.
Lightheadedness.
Fainting.
Rapid or irregular pulse.
Treatment of Aortic Regurgitation.
Beta-blocker medications may slow progression in those with Marfan's Syndrome.
Vasodilator medications such as Ace inhibitors, hydralazine, and nifedipine can decrease the severity of the regurgitation.
Surgical valve replacement in those with symptoms or vital left ventricular dysfunction.
