Aortic valve regurgitation
Aortic regurgitation is leakage of the aortic valve each time the left ventricle relaxes.The volume and pressure of blood in the left ventricle may increase. As a result, the heart may have to do more work to compensate. The walls of the ventricle will sometimes thicken, and a thickened heart muscle is less effective. Eventually, the heart maybe unable to meet the body’s need for blood, leading to heart failure.
