This is called aortic regurgitation and over time weakens the heart muscle. (sutterhealth.org)
Aortic regurgitation, on the other hand, has many causes: degeneration of the cusps, endocarditis, bicuspid aortic valve, aortic root dilatation, trauma, connective tissue disorders such as Marfan syndrome or Ehlers-Danlos lead to imperfect closure of the valve during diastole, hence the blood is returning from the aorta towards the left ventricle of the heart.

Patients couldn't have had mitral-valve surgery within 48 hours, extremely high risk of bleeding, transient Afib caused by surgery, or a mechanical valve. (medpagetoday.com)
After his initial research, Scott was going to select a mechanical valve. (heart-valve-surgery.com)
Coumadin) to prevent clotting on aortic mechanical valve options , the more concerned he became. (heart-valve-surgery.com)
In propensity-matched comparisons, actuarial 15-year mortality rates were 60.6% with the bioprosthetic aortic valve and 62.1% with the mechanical valve. (medscape.com)

Although the incidence of structural valve deterioration is negligible, these prostheses have significant limitations at the time of implant due to the lack of appropriately sized prostheses for small children and neonates. (medscape.com)
