Aortic valve replacement
Aortic Valve Replacement
Aortic valve replacement (pronunciation: ay-OR-tik VALV ree-PLAYS-ment) is a surgical procedure used to replace a diseased or malfunctioning aortic valve in the heart. The aortic valve is one of the four valves in the heart that regulate blood flow.
Etymology
The term "aortic" is derived from the Greek word "aortē", meaning 'the great artery', and "valve" comes from the Latin "valva", meaning 'leaf of a door'. "Replacement" is derived from the Old French "reemplacier", meaning 'to fill up an empty space'.
Procedure
During an aortic valve replacement, the patient's diseased aortic valve is removed and a new one is sewn into place. The new valve can be a mechanical valve, made from materials such as plastic, carbon, or metal, or a biological valve, made from animal or human tissue.
Related Terms

- Aortic Regurgitation: A condition where the aortic valve does not close properly, causing blood to leak back into the heart.

Risks and Complications
As with any surgical procedure, aortic valve replacement carries some risks, including infection, bleeding, and heart attack. Long-term complications may include blood clots and valve dysfunction.
