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 replacement of the aortic valve?

What is a replacement of the aortic valve?

AVR: Exactly what it says. If there is a problem with the aortic valve (between left ventricle and aorta) (either narrowed -stenotic- or leaking -insufficient) it can be surgically replaced. It can be replaced with a mechanical "metal" or tissue valve "pig valve". ...Read more

What is the effect of a pacemaker after aortic valve replacement?

What is the effect of a pacemaker after aortic valve replacement?

Pacemaker and AVR: After an aortic valve replacement the pacemaker works the same way to keep the heart from going too slow. Sometimes with aortic valve disease the conduction system gets damaged because it is close to the valve, and the patient needs a pacemaker. ...Read more

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

What is the function of mitral valve?

Mitral valve: The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common. ...Read more

What is the function of aortic valve?

Aortic Valve: The aortic valve is an integral part of the heart and is located between the left ventricle and the aorta. It opens when the left ventricle contracts (systole) and allows blood to be pumped into the aorta. It closes when the left ventricle fills (diastole). It's function is to prevent blood from flowing back from the aorta while the heart is filling. ...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

How long of a procedure is a mitral valve replacement?

How long of a procedure is a mitral valve replacement?

4 hours: The surgery might take approximately 4 hours. You would expect to spend, on average, 5 days in the hospital. Complete recovery takes approximately 2 months. If the repair is done in a minimally invasive fashion, the hospital stay might be 3-4 days and full recovery might take only one month. ...Read more

What is the location of the mitral bicuspid valve?

What is the location of the mitral bicuspid valve?

Mitral location: Calling it a bicuspid mitral valve is redundant. The mitral valve has two (bi) leaflets and was named for its appearance similar to a bishop's miter. It is located between the left atrium and ventricle and its function is to prevent blood from flowing back into the left atrium when the left ventricle contracts and pumps its content into the aorta. ...Read more

What is the function of the mitral valve in a newborn?

What is the function of the mitral valve in a newborn?

Same as adult: Any valve (heart, vein) prevents blood from flowing in the wrong direction. So when you heart muscle contracts, the blood can only move forward if the valve is not leaking. Age has nothing to do with it. ...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

What is the pathogenesis of a mitral valve prolapse ?

What is the pathogenesis of a mitral valve prolapse ?

Myxomatous change: Mitral valve prolapse is due to the mitral valve tissue being slightly redundant. Often this is related to slight thickening of the tissue and stretching of the chords that guide how far the valve moves. Sometimes the valve leaks, other times not. In may cases this is completely benign. Sometimes people feel their heart skip. ...Read more

Mitral Valve Replacement (Definition)

The mitral valve is a valve between the left atrium and left ventricle. When the heart squeezes to pump blood to the body, this valve prevents blood from backing up into the lungs. When this valve is malfunctioning, surgeons can either repair or replace the valve. The valve can be replaced with either a mechanical or a tissue valve. This is called mitral ...Read more
