The mitral valve sits in the left side of the heart. It helps to control the flow of blood from the top part of the heart to the bottom part. The valve makes sure the blood moves in one direction.
Mitral regurgitation is a leak in this valve. Blood leaks back into the upper chamber. Minor leaks may not be noticed. Severe leaks can cause serious symptoms and illness. The sooner it is treated, the better the outcome.
Your doctor will ask about your symptoms and health history. A physical exam will be done. A leaking heart valves will make a sound called a murmur. The doctor may be able to hear it during an exam. You will likely be referred to a cardiologist.
Images of the heart will help to find which valve is damaged. Image options include:
Treatment will be based on how severe the leak is. It will also depend on how it is affecting overall heart health. Severe regurgitation can cause congestion in the lungs. Overtime, it will also cause an enlargement of the heart muscle.
Treatment options include the following:
When possible the underlying cause will be treated. It may allow the valve to work normally again.
Medicine may help decrease symptoms and effects on the heart. It is an option for those with less severe and slow progressing disease.
Medicine may also help to stabilize severe disease for a short time. It may be used to stabilize someone before surgery. A pump may also be needed to help support the heart to be ready for surgery.
Valves that are causing severe problems or getting worse fast will need surgery. The valve will be repaired or replaced.
