Aortic Valve Replacement (AVR) by Arthur Thomas Martella, MD and Bob Kiaii, MD
Procedure Overview
Procedure Overview
The Aortic Valve Replacement (AVR) procedure treats diseases affecting the aortic valve, through which blood from the left ventricle enters the aorta. If the aortic valve can't be repaired, surgery may be needed to replace the valve. In this procedure, a surgeon removes the aortic valve and replaces it with a mechanical valve, or a valve made from cow, pig or human heart tissue (biological tissue valve).
INDICATIONS:
- Stenosis: When calcium deposits build up on the valve, the valve opening become narrowed, inhibiting the flow of blood out of the ventricle.
Regurgitation: The valve does not close completely, causing the blood to flow backward into the left ventricle at the end of systole.
