What is the structure of mitral valve?

What is the structure of mitral valve?

Not just the leaflet: The mitral valve has two leaflets that open and shut. However, there is an important supporting structure. The leaflets attach to thin chordae tendinae, dental floss-like chords that connect leaflets to papillary muscles. The pap muscles are bands of muscle tissue arising from the wall of the heart, whose contraction and relaxation transmit force to the leaflets. ...Read more

Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

What is a mitral valve?

What is a mitral valve?

One of 4 heart valve: The mitral valve is one of the 4 heart valves found in the heart. These valves keep blood moving one direction rather than back and forth as the heart contracts. The mitral valve is so named as it looks like the pope's hat (a mitre). The mitral valve separates the left atrium and the left ventricle. ...Read more

Is it possible for mitral valve to prolapse by medication aggravation?

Is it possible for mitral valve to prolapse by medication aggravation?

What symptoms: Meds do not usually change valve structure except for diet pills like phen-fen. Meds do, however, commonly cause chest pain or palpitations which are sometimes falsely associated withmvp. ...Read more

What is the significance of hydro elastoma of the mitral valve?

What is the significance of hydro elastoma of the mitral valve?

Rupture?: The hydro elastoma is a filament that is attached to the mitral valve and other structures of the left heart that has the potential to rupture and embolize, meaning that remnants and particles of it could move through the blood stream potentially block flow. ...Read more

What is a leak in the mitral valve?

What is a leak in the mitral valve?

Backward flow: The leaflets of the valve are not closing perfectly and some blood goes backwards from the left ventricle into the left atrium. Minor leaks are common and benign. ...Read more

Can mitral valve prolapse kill me?

Not by itself: Mitral valve prolapse is a disorder of the mitral valve where the leaflets close abnormally. By itself patients have no symptoms. But patients with mvp have an increased incidence of developing a leak-mitral regurge. Occasionally it will worsen, and left untreated could lead to heart failure. Mvp patients need to take antibiotics before surgical procedures including dental to prevent infections. ...Read more

Can regurgitation start at anytime with mitral valve prolapse?

Yes: While the technical answer is yes, it's more complicated: mvp encompasses a broad range of severity from trivial/normal variant to very severe. Commonly there is some degree of regurgitation, often mild. The rare, severe forms of mvp can suddenly rupture a chordae (a supporting structure of the valve) and suddenly develop severe regurgitation with symptoms. This can happen anytime. ...Read more

What is the movement of mitral valve calcification?

What is the movement of mitral valve calcification?

Mitral calcification: Under certain circumstances and with advanced age, the leaflets of the mitral valve can become loaded with calcium. This makes the leaflets stiffer and can limit the opening of the valve (mitral stenosis), causing a restriction of blood flow through the heart. There is another form of calcification in the mitral ring which usually does not cause any symptoms. ...Read more
