Understanding Open Mitral Valve Replacement
A mitral valve replacement is a surgery to replace a mitral valve that doesn’t work well. It’s replaced with a new valve. Open-heart surgery is a procedure for mitral valve repair. It’s done with an incision in the middle of the chest that goes through your breastbone.
Why mitral valve replacement is done
The mitral valve is one of the heart’s 4 valves. These valves help the blood flow through the heart’s 4 chambers and out to the body. The mitral valve lies between the left atrium and the left ventricle.
The surgery is done if the mitral valve is not working well. This may be the case if you have either of the below:
Mitral valve regurgitation. This is also known as mitral valve insufficiency. This is a leaky valve that lets blood flow backward in the heart. This can occur because of a heart defect you were born with, damage from a heart attack, advanced age, or a bacterial infection in your valve.
Narrow mitral valve. You might have been born with this narrowed valve. But it can also occur because of damage from rheumatic fever.
These conditions can put stress on the heart and lead to symptoms such as shortness of breath, fatigue, and swelling in your body. A new valve can let blood flow through your heart and out to your body normally again.
How mitral valve replacement is done
Your procedure will be done by a cardiac surgeon. This is a doctor who treats diseases of the heart. He or she will work with a team of specialized nurses. You will be hooked up to a heart-lung machine. This machine will act as your heart and lungs during the surgery. The surgeon will make a cut (incision) down the middle of your chest. To reach your heart, the doctor will separate the breastbone. He or she will take out your mitral valve. It will be replaced with a new valve.
Risks of open mitral valve replacement
All surgery has some risks. The risks of open mitral valve replacement include:
Irregular heart rhythms
Blood clots that can lead to stroke or heart attack
Complications from anesthesia
Damage to the arteries of the heart
Your own risks may vary according to your age, your general health, and the reason for your procedure. They may also vary depending on the structure of your heart. Talk with your healthcare provider about which risks apply most to you.
