what causes mild mitral valve prolapse?

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.

Mitral valve prolapse (MVP) is a condition in which the heart's mitral valve doesn't work well. The flaps of the valve are “floppy” and may not close tightly. These flaps normally help seal or open the valve.

A very small amount of mitral regurgitation is common. But some people have severe mitral valve regurgitation. Mitral valve regurgitation can be acute or chronic. With the acute condition, the valve suddenly becomes leaky.

However, in the most serious cases it can cause abnormal heartbeats (arrhythmias) that may eventually become life-threatening. When mitral valve prolapse is severe enough to cause significant valve leakage, called “regurgitation,” it can lead to serious complications such as heart attack and stroke.

Mitral Valve Prolapse. Mitral valve prolapse, also known as click-murmur syndrome, Barlow's syndrome, balloon mitral valve, or floppy valve syndrome, is the bulging of one or both of the mitral valve flaps (leaflets) into the left atrium during the contraction of the heart.

The exact cause of mitral valve prolapse (MVP) isn't known. Most people who have the condition are born with it. MVP tends to run in families. Also, it's more common in people who are born with connective tissue disorders, such as Marfan syndrome.

Mitral valve prolapse is a common cause of mitral regurgitation. That's a condition in which some blood flows backward through the mitral valve with each heartbeat. Over years, moderate or severe mitral regurgitation can cause weakness of the heart muscle, known as congestive heart failure.

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 regurgitation can cause complications such as: Atrial fibrillation, in which the atria of the heart don't contract well. This leads to increased risk of stroke. Elevated blood pressure in the lungs (pulmonary artery hypertension)

Background: Mitral valve prolapse (MVP) is the most common primary valvular abnormality in a young population. In some individuals, MVP is silent or associated with palpitations, dizziness, chest pain, and abnormal electrocardiogram (ECG) repolarization with or without ventricular arrhythmias.

Rarely, a mitral prolapse may even cause sudden death. Classic MVP is the type of mitral prolapse most likely to cause deadly complications, particularly when leaflet displacement is flail and asymmetric. This type usually accompanies disturbing mitral valve prolapse symptoms.

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.

Anxiety, panic attacks, and depression may be associated with mitral valve prolapse. Like fatigue, these symptoms are believed to be related to imbalances of the autonomic nervous system. Migraine headaches have been occasionally linked to mitral valve prolapse.

Cardiac arrhythmias are frequently detected in patients with mitral valve prolapse (MVP) The proper mechanisms causing ventricular arrhythmias in patients with MVP have not been fully investigated. In the current issue of the International Journal of Cardiovascular Imaging, Turker et al.

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.

The papillary muscles pull the chordae tendineae taut during ventricular contraction, which prevents prolapse of the atrioventricular valves into the atria. Dysfunction of a papillary muscle would prevent some of the chordae from functioning properly, which could lead to valvular prolapse.
