  Mitral valve prolapse - Wikipedia, the free encyclopedia
Mitral valve prolapse (MVP) is a heart valve condition marked by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole.
The mitral valve, so named because of its resemblance to a bishop's miter, is the heart valve that prevents the backflow of blood from the left ventricle into the left atrium.
Patients with asymmetric prolapse are prone to severe deterioration of the mitral valve, with the possible rupture of the chordae tendineae and the development of a flail leaflet.

 Mitral valve prolapse   (Site not responding. Last check: 2007-11-04)
Mitral valve prolapse (MVP) is a ballooning of the support structures of the mitral heart valve into the left upper collection chamber of the heart.
The mitral valve is located on the left side of the heart between the top chamber (left atrium) and the bottom chamber (left ventricle).
The valve opens and closes according to the heartbeat and the pressure that is exerted upon it from the blood in both chambers.

 What is Mitral Valve Prolapse?
Located between the upper left chamber and lower left chamber of the heart, the mitral valve is made of two flaps of tissue that normally open and close in a rhythmic way to allow blood to flow in one direction--from the atrium (upper chamber) to the ventricle (lower champer).
Mitral valve prolapse is the most common cardiac problem and may affect five to twenty percent of the population.
MVP tends to run in families, so those with blood relatives with MVP have a greater chance of also having the condition.

 Mitral Valve Prolapse
Mitral valve prolapse is one of the most frequently made cardiac diagnoses in the United States.
In mitral valve prolapse the shape or dimensions of the leaflets of the valve are not ideal; they may be too large and fail to close properly or balloon out, hence the term "prolapse." When the valve leaflets flap, a clicking sound may be heard.
Sometimes the prolapsing of the mitral valve allows a slight flow of blood back into the left atrium, which is called "mitral regurgitation," and this may cause a sound called a murmur.

 Mitral valve prolapse
Mitral valve prolapse (MVP) is a disorder that affects one of your heart's valves — the mitral valve.
When your heart is working properly, the mitral valve opens and closes to regulate the movement of blood between your heart's upper left chamber (left atrium, or holding chamber) and the lower left chamber (left ventricle, or pumping chamber).
The most common problem is mitral valve regurgitation (mitral insufficiency) — a condition in which the valve is particularly leaky and allows excessive blood back into the left atrium.

Mitral valve prolapse (also known as "click murmur syndrome" and "Barlow's syndrome") is the most common heart valve abnormality, affecting five to ten percent of the world population.
A normal mitral valve consists of two thin leaflets, located between the left atrium and the left ventricle of the heart.
Mitral valve leaflets, shaped like parachutes, are attached to the inner wall of the left ventricle by a series of strings called "chordae." When the ventricles contract, the mitral valve leaflets close snugly, preventing backflow of blood from the left ventricle into the left atrium.

MVP may be secondary to rupture or dysfunction of the papillary muscles following myocardial infarction or ischemia, rupture of chordae tendineae due to infective endocarditis, or abnormal left ventricular wall motion in the setting of myocardial ischemia and/or primary myocardial disease.
Timing and degree of the prolapse are determined by the position of the mitral leaflets at end diastole, which in turn is dependent on the distance from the mitral valve annulus to the attachment of the chordae to papillary muscles.

Mitral valve prolapse is a condition affecting one of the four major heart valves.
When a valve prolapses, it bulges or stretches when closing, oftentimes producing a click or snapping sound that can be heard through a stethoscope.
If the valve opens slightly as well and allows blood to leak in the wrong direction, a murmur can be heard, caused by a spurt under high pressure through a small opening.

The mitral valve is the valve that allows oxygenated blood into the left ventricle from the left atrium.
When closed, the mitral valve prevents a backflow of blood, and when open, permits the blood to move forward to its next destination.
When a valve fails to close properly, as is the case in a common disorder called mitral valve prolapse, there is a regurgitation or backflow of blood.
