'''Aortic valve replacement''' is a surgical procedure in which a patient's [[aortic valve]] is replaced with an artificial valve. The aortic valve is one of the four main valves in the [[heart]], and it plays a crucial role in ensuring unidirectional blood flow from the [[left ventricle]] to the [[aorta]].

==Early Life and Education==
Aortic valve replacement is typically indicated for patients with severe [[aortic stenosis]] or [[aortic regurgitation]]. Aortic stenosis is a condition where the valve becomes narrowed, restricting blood flow, while aortic regurgitation occurs when the valve does not close properly, allowing blood to flow backward into the heart.

Recovery from aortic valve replacement varies depending on the type of surgery performed. Patients who undergo open-heart surgery may require several weeks to recover, while those who have minimally invasive procedures may recover more quickly. The prognosis after aortic valve replacement is generally good, with many patients experiencing significant improvement in symptoms and quality of life.
