Which heart valve is most commonly replaced?

Aortic Valve: The most commonly replaced heart valve in the us is the aortic valve. The process of valve disease, usually leading to the tightening of the valve (stenosis) is very similar to that of the development of CAD which is very common in the us. In the developing countries, rheumatic fever in childhood can lead to both mitral and aortic valve disease in the adulthood, but this is not common in the us.

Valves : In the current era the aortic valve is more commonly replaced while the mitral valve in many cases can be repaired.

Aortic, then mitral: It is close between the two, but the aortic valve is the most commonly replaced, as aortic stenosis is common in older folks. The mitral valve is now often repaired rather than replaced. Pulmonary valve surgery is usally for congenital problems and done in children, while replacement of the tricuspid valve is rare.

Valve replacement: The aortic and mitral valves are the ones most commonly replaced. The aortic is probably a bit more commonly replaced than the mitral.
