Deaths follwing mitral valve replacement

The mitral valve is one of the valves in the heart. Sometimes, the mitral valve is diseased and needs to be replaced. A mitral valve replacement is the surgery performed to replace the diseased mitral valve. It is considered an isolated mitral valve replacement when it is not done in conjunction with any other surgeries.

Mitral valve replacements require proficiency with the use of complex equipment; and technical errors may lead to serious complications, such as heart attack, stroke, and death.

About this measure

Mortality is the statistical measure of the percentage of people who die. This measure tracks the percentage of patients from 2011 who had an isolated mitral valve replacement and died within 30 days, either during hospitalization or 30 days after discharge.
 

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