The mitral valve controls the flow of blood into the main pumping chamber (left ventricle) of the heart (see figure 1). Mitral valve disease is where the valve does not open properly or is narrowed, or does not close properly. This causes pressure on the heart and lungs, causing symptoms of palpitations, breathlessness and dizziness.
What are the benefits of surgery?
The main benefits of surgery are to relieve breathlessness and chest pain and improve energy levels. You should live longer with surgery.
Are there any alternatives to surgery?
Drug treatments such as diuretics, ACE-inhibitors and digoxin are the main alternatives to surgery.
What does the operation involve?
The operation is performed under a general anaesthetic and usually takes between two and three hours.
Your surgeon will make a cut down the front of your chest, through the breastbone. You will be connected to a heart-lung machine, which allows the heart to be opened and the valve replaced or repaired. The two main types of replacement valve are mechanical or tissue valves.
What complications can happen?
1. General complications of any operation
Pain
Bleeding
Unsightly scarring
Blood clots
2. Specific complications of this operation
Stroke
Infection in the chest wound
Heart attack
Death
How soon will I recover?
After the operation you will be transferred to the cardiac intensive-care unit or high-dependency unit, usually for 24 hours, and then to the ward.
You should be able to go home after seven to ten days.
Your surgeon, physiotherapist and occupational therapist will tell you when you can return to normal activities.
Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, you should ask a member of the healthcare team or your GP for advice. Most people make a good recovery, with no more breathlessness or chest pain. You may have more energy after you recover.
Summary
Mitral valve disease can cause pain, shortness of breath and eventually death. Mitral valve surgery can relieve your pain, improve your energy levels and may help you to live longer.
