Deaths following mitral valve repair plus heart bypass surgery (CABG)

The mitral valve is one of the valves in the heart. Sometimes the mitral valve is diseased and requires surgery. In some cases, the mitral valve can be repaired instead of replaced. This surgery is called a mitral valve repair surgery and because the patient’s native valve remains in place, valve repair is preferred in most cases over valve replacement.

Heart bypass surgery, also known as coronary artery bypass graft (CABG) surgery, creates a detour or bypass around the blocked or diseased portion of the coronary artery using an artery or vein from the body to restore the blood supply to the heart muscle.

Mitral valve repairs and CABG 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 a mitral valve repair plus a CABG surgery and died within 30 days, in the hospital or after discharge.

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