What are the causes mitral stenosis?

Infections. Most common cause, although rare these days in the westernized world, is rheumatic fever (due to strep infectipns) in young age, which leads to scarring of the valve over time with narrowing - stenosis. Other infections (endocarditis) can lead to mitral stenosis as well.
Rheumaic fever. Usually repeated strep infections as a child lead to rheumatic fever which can scar the heart and make the valve thickened and hard to open.

How is it that mitral stenosis causes dyspnea?

Mitral stenosis. Ms is like a door that doen't open enough to let the blood out of the lungs. This engorgemnt of the lungs causes increased work of breathing and decreased oxygen exchange. Read more...
Depends on severity. If severe, mitral stenosis can cause pulmonary edema or fluid buildup in the lung tissue and air spaces as a result of increasing left atrial pressure and pulmonary venous congestion. This may led to shortness of breath as well as crackles on exam. Read more...

Could you tell me why mitral stenosis causes dyspnea?

Multiple causes. Dyspnea is difficult breathing. Ms causes this in multiple ways. Increased lung water (back up into the lungs.) dilated left atrium compressing the left main stem bronchus. Decreased cardiac output (and o2 delivery) leading to a sensation of needing to breathe harder. Atrial arrhythmias leading to decreased cardiac output and increased water in the lungs. Each person has variable contribution. Read more...

If a patient has mitral stenosis how will this cause failure of the heart?

Right heart failure. Blood backs up in the left atrium which overflows into the two vena cavae which lead to distention of these veins which swells the liver and the ankles. If it becomes more severe, then, the right ventricle distends and blood backs up into the lungs and causes shortness of breath. This is called right heart failure. Also, insufficient blood gets to the rest of the body because the left ventricle. Read more...

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...
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 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...

Is mitral stenosis inherited?

Not usually. Most mitral stenosis is not inherited and is a result of rheumatic fever but rarely it is congenital, that is you are born with it. One form of congenital mitral stenosis includes an atrial septal defect and is called lutembacher's syndrome. It was described by rene lutembacher. Read more...
Yes but rare! Mitral stenosis can be inherited although rare. Some of the congenital causes of mitral stenosis include parachute mitral valve (the strings that tether the valves are attached to one papillary muscle instead of two), double orifice mitral valve where instead of one large opening it has two small openings, small rim of the valve known as hypoplasia of the annulus and congenital thickening/fusion.
