Mitral valve surgery: percentage of valves replaced

The mitral valve is one of the valves in the heart. Sometimes the mitral valve is diseased and requires surgery to replace it. This surgery is considered an isolated mitral valve replacement when it is not done in conjunction with any other surgeries.

A lower percentage of mitral valve replacement surgeries are considered advantageous to the patient because mitral valve replacement surgery requires patients to take blood thinners for the rest of their lives. Taking blood thinners may result in lifestyle modifications such as sports or activity restrictions and dietary constraints.

About this measure

This measure tracks the percentage of isolated mitral valve replacement surgeries the hospital performed in 2012. See mitral valve repair surgery: percentage of valves repaired to view the percentage of mitral valves the hospital repaired in 2012. The second graph shows a trend over time for this measure.

Note: In this case, a lower number is better.
