Diagnosis. Doctors may diagnose mitral valve prolapse at any age. Your doctor is most likely to diagnose mitral valve prolapse while listening to your heart with a stethoscope during a physical examination. If you have mitral valve prolapse, your doctor may hear a clicking sound, which is common with this condition.

Mitral valve prolapse, also called MVP, is a condition in which the two valve flaps of the mitral valve don't close smoothly or evenly, but bulge (prolapse) upward into the left atrium. Mitral valve prolapse is also known as click-murmur syndrome, Barlow's syndrome or floppy valve syndrome.

Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse is also seen with some connective tissue disorders such as Marfan syndrome and other rare genetic disorders. It is also sometimes seen in isolation in people who are otherwise normal.

Symptoms. Some people with mitral valve disease might not experience symptoms for many years. Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include: Abnormal heart sound (heart murmur) heard through a stethoscope.

Mitral valve prolapse causes no problems for most people, so treatment is usually not needed. People who develop severe mitral regurgitation due to mitral valve prolapse often can benefit from surgery to repair or replace the leaky valve.

Although mitral valve prolapse is usually a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart condition. When signs and symptoms do occur, it may be because blood is leaking backward through the valve.

Mitral valve prolapse is most often caused by idiopathic myxomatous degeneration of the mitral valve and chordae tendineae. Mitral regurgitation (MR) is the most common complication. Heart sounds often include a sharp, mid-systolic click that occurs earlier with the Valsalva maneuver.

When severe, mitral regurgitation can lead to heart failure and abnormal heart rhythms. Most people are unaware of the prolapsing of the mitral valve. However, others may experience a number of symptoms. The mitral valve prolapse (MVP) syndrome has a strong hereditary tendency, although the exact cause is unknown.

Mitral valve prolapse is usually caused by problems with the tissues that join the mitral valve to the heart muscles. Some people with the condition are born with it, and it's more common in people with connective tissue disorders, such as Marfan syndrome.

But in some people with mitral valve prolapse, one or both of the mitral valve leaflets have extra tissue or stretch more than normal, which causes them to bulge like a parachute into the left atrium each time the heart contracts. The bulging may keep the valve from closing tightly.

Chest pain is the most frequent symptom in people who have symptoms with mitral valve prolapse. The chest pain may be very bothersome and frightening, but it does not increase the risk of heart attack, death, or other heart problems.

Mitral Valve Prolapse (Click with Late Systolic Murmur) Sounds. There is a medium pitched diamond shaped murmur which begins right after a mid systolic click and runs to the end of systole.

Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include: Abnormal heart sound (heart murmur) heard through a stethoscope. Shortness of breath (dyspnea), especially when you have been very active or when you lie down. Fatigue.

Though most people with mitral valve prolapse don't need surgery, your doctor may suggest surgical treatment if you have severe mitral valve regurgitation, whether you have symptoms or not. Severe mitral valve regurgitation can eventually cause heart failure, preventing your heart from effectively pumping blood.

Most of the time, mitral valve prolapse causes few symptoms or complications initially. In some people, it does not cause any symptoms at all. However, mitral valve prolapse may get worse over time.

Mitral valve prolapse can develop in any person at any age. Serious symptoms of mitral valve prolapse tend to occur most often in men older than 50. Mitral valve prolapse can run in families and may be linked to several other conditions, such as: Marfan syndrome.
