What is mitral valve regurgitation?

What is mitral valve regurgitation?

Leaky: Your heart valves are supposed to be one way doors. Blood is supposed to be pushed out in one direction with the valve (door) closing behind. If the door doesn't close completely and or some blood leaks backward it is called regurgitation. A little bit is not a problem, a large amount can make the heart need to work too hard. ...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 mitral valve stenosis?

What is mitral valve stenosis?

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 mitral regurgitations?

What is mitral regurgitations?

MR: The mitral valve has 2 leaflets which separates the left ventricle from the left atrium. Blood passes across the mv from the la to the lv when the heart is filling. When the ventricle contracts, the mv is closed and no blood goes backward into the la unless regurgitation is present. Then the blood leaks backward, overfilling the la and raising the pressure. ...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

What is mitral stenosis?

What is mitral stenosis?

Narrowing : Mitral stenosis is a narrowing of the valve that controls the flow of blood from the left atrium to the left ventricle of the heart. This can have many causes and, depending upon the severity of the stenosis, may or may not cause symptoms. This must be followed, because the degree of stenosis can increase over time and require replacement. ...Read more

What is mitral stenosis?

Valve tightening: This is a situation where the mitral valve is tight, producing some restriction to blood flowing through.It can either be something a person is born with or something that is caused by disease. ...Read more

What is "trivial mitral valve regurgitation"?

What is "trivial mitral valve regurgitation"?

Very small leak: The mitral valve prevents blood from flowing backwards out of the main pumping chamber of the heart (left ventricle). When a valve leaks we call this regugitation or insufficiency. One method of describing a leak is to classify it as trivial, mild, moderate, or severe. A trivial leak should not affect you heart in any way. A lot of people of this and never need anything done for it. ...Read more

What is mitral regurgitation and prolapse?

What is mitral regurgitation and prolapse?

Different things: I think of mitral valve prolapse as a description of how the valve closes (the leaflets bow into the atrium). Regurgitation is actual leaking of blood back in the atrium. You can have prolapse without regurgitation. And not everyone with regurgitation has prolapse. There is a group of patients that develop regurge from prolapse, but not everyone. ...Read more

What is tricuspid regurgitation?

What is tricuspid regurgitation?

A leaky & weak valve: The heart is a machine with plumbing. There are four holding tanks. Two upper and two lower. There are 4 valves in the heart that regulate the outflow. On the right side of the heart the blood is pumped to the lungs to get oxygen. The valve that is between the upper and lower is called the tricuspid valve. When it is damaged blood pushed from the top to the bottom leaks back into the top. ...Read more

What is rheumatic mitral valve obstruction?

What is rheumatic mitral valve obstruction?

MitralValve stenosis: There are 4 valves in the heart. The mitral valve is between the left atrium and left ventricle, and is the valve most often damaged by rheumatic heart disease (rheumatic fever after strep infections). Damage to the mitral valve causes its 2 flaps to thicken, stiffen, come closer together, and/or get attached to one another, leaving a smaller opening in the center of the valve, thus blocking flow. ...Read more

What is a trace of mitral valve regurgitation?

What is a trace of mitral valve regurgitation?

Very small leak: The mitral valve prevents blood from flowing backwards out of the main pumping chamber of the heart (left ventricle). When a valve leaks we call this regugitation or insufficiency. One method of describing a leak is to classify it as trivial or trace, mild, moderate, or severe. A trace leak should not affect you heart in any way. A lot of people of this and never need anything done for it. ...Read more

What is pulmonary valve stenosis?

What is pulmonary valve stenosis?

Pulmonary stenosis: Pulmonary stenosis is used to describe a condition in which the heart valve which is associated with the right-sided heart chamber which pumps deoxygenated blood to the lungs is narrowed thereby impeding blood flow to the lungs. ...Read more

Why is mitral valve prolapse effective?

Why is mitral valve prolapse effective?

Mitral valve prolaps: I will assume you did not mean effective but harmful :-) when the valve leaflets "prolapse" they bend back and no longer seal, resulting in significant leakage of the valve. This increases the amount of work the heart has to perform, resulting in decrease in exercise capacity and more shortness of breath. Of course, the leakage can be a little with few symptoms or severe... ...Read more

What is the significance of mitral valve prolapse?

What is the significance of mitral valve prolapse?

Depends: Most of the time, it is a minor problem. It can result in significant leakage of the valve, chest pain, palpitations, valve infection, and heart rhythm disturbances. So it really depends on the severity of the problem. Fortunately, most cases are relatively benign. We used to routinely give antibiotics prior to dental and other procedures, but that is no longer recommended. ...Read more

What is aortic valve disease?

What is aortic valve disease?

Aortic Valve: The aortic valve functions as a valve -no surprise here-. So it can either leak or be restricted (stenotic). Both conditions, when severe, need to be corrected. This is usual done by replacing the defective valve with an artificial one. There are many conditions/diseases that can cause the valve to leak or be restricted. ...Read more

What is the significance of mitral valve stenosis?

Mitral stenosis: Mitral stenosis is a narrowing of the mitral valve caused by rheumatic fever. Progressive narrowing of the mitral valve can cause heart rhythm disturbances and the development of heart failure symptoms. This condition can be corrected with either mitral balloon valvuloplasty or surgery. ...Read more
