There are four valves in the heart. The mitral valve is one of the main valves on the left side of the heart between the left atrium and left ventricle.

It has two cusps (leaflets) that open to allow blood flow from your left atrium to your left ventricle.

The leaflets close preventing blood from flowing backward into the left atrium and into your lungs.

Why should I get a mitral valve repair instead of a replacement?

Toggle accordion item

A mitral valve repair is the optimal surgical treatment for mitral valve disease instead of a replacement.

A repair helps preserve your own heart's shape and function. It also allows for a better survival rate from surgery with a 1-2 percent mortality rate. Another advantage to a repair is freedom from lifelong anticoagulants or blood thinners. If you have a mechanical mitral valve replacement, you may have to stay on blood thinners for the rest of your life. If you have a repair, you would only have to take a low-dose aspirin.
