The mitral valve is located in the heart’s left ventricle between the upper and lower chambers. This valve opens to allow blood to move from the upper atrium and the lower ventricle on the left side of the heart, and then closes to prevent the backflow of blood.
Normally, heart valves are fairly rigid, and they open and close completely with regularity. A prolapsed valve is loose and a little floppy so that it doesn’t shut as firmly as it should. It may close with a faint click and may permit a tiny amount of blood to leak through, producing a heart murmur.
A large mitral valve prolapse can allow blood to seep back into the heart’s top chamber. This is called mitral regurgitation or a “leaky valve.”
What Are the Symptoms and Complications of MVP?
Many people live their whole lives without symptoms of MVP. Those who do have symptoms may experience heart palpitations, chest pain, fainting, shortness of breath, reduced stamina, fatigue, or generalized weakness.
The main concern for those living with MVP is that long-term complications can arise if the condition is not properly treated.
Endocarditis
The risk of developing endocarditis, a heart infection, is a rare but potential complication of having a leaky heart valve.
Mitral Regurgitation
Mitral regurgitation is the backflow of blood from the ventricle to the atrium. Mitral regurgitation can lead to enlargement of the cardiac chamber, weakening of the heart muscle, and, in some cases, heart failure.
Treatment
Treatment for MVP varies depending upon the extent of the prolapse. Your symptoms and staging can help your doctor decide whether you need treatment.
How to Exercise When You Have MVP
It’s important to discuss your individual symptoms with your physician before starting an exercise plan. The heart is a muscle that gets stronger with exercise. Aerobic exercise strengthens the heart and makes it more efficient. This type of exercise is generally recommended for people who have MVP.
Aerobic exercise includes walking, jogging, swimming, or cycling. A moderate pace for 30 minutes at a time is a good way to get started. You should monitor your heart rate and slow down if you feel your heart racing or if you start to feel dizzy or lightheaded.
People who experience chest pains, heart palpitations, or other significant symptoms of MVP are sometimes given beta-blockers to slow the heart rate during exercise. Rarely is someone discouraged from exercise because of mitral valve prolapse.
Your cardiologist may ask you to undergo an exercise tolerance test during which you would have an electrocardiogram (ECG) while on a treadmill or stationary bike. The results of this test can determine how much exercise you can safely perform without compromising your mitral valve.
