Stenosis, Spinal Causes, Symptoms and Treatment and Related Disorders ...
Stenosis, pulmonary: The pulmonary valve is too tight so that the flow of blood from the right ventricle of the heart into the pulmonary artery is impeded. This means the right ventricle must pump harder than normal to overcome the obstruction.
Stenosis
An abnormal narrowing of any opening or tube shaped passage in the body.

Spinal stenosis
The pathway in the human body in which the spinal cord and nerves run through is called the spinal canal. When the spinal canal narrows it will increase the pressure that is put on the nerves.
Aortic stenosis
Aortic stenosis is the abnormal narrowing of the aortic valve, which restricts the flow of blood from the ventricle into the aorta. Normally, blood carrying oxygen (oxygenated) enters the left upper chamber (atrium) of the heart.
Mitral Stenosis
Mitral stenosis is a narrowing of the mitral valve in the heart. This restricts the flow of blood through the valve. Back pressure which builds up behind the narrowed valve can cause various problems and symptoms.

Aortic Stenosis - Side effects
The MedicineNet physician editors ask:
What side effects did you have with your aortic stenosis?
Stenosis of the mitral valve typically occurs decades after the episode of acute rheumatic carditis. Acute insult leads to formation of multiple inflammatory foci (Aschoff bodies, perivascular mononuclear infiltrate) in the endocardium and myocardium.
Stenosis occurs when the valve cannot open wide enough. As a result, less blood flows to the lungs.
Alternative Names ...
Stenosis of the carotid arteries may occur over many years. When the surface of the plaque in an artery cracks or ruptures, clot-forming substances in the blood rapidly gather at the site. A clot, called a thrombus, then forms in the artery.
When stenosis occurs in the lower back, it is called lumbar spinal stenosis. It often results from the normal aging process. As people age, the soft tissues and bones in the spine may harden or become overgrown.
Aortic stenosis is a narrowing of the aorta, the artery connected to the left ventricle of the heart, through which oxygenated blood flows to return to the body. The most common cause of aortic stenosis is congenital, present at birth.
Spinal stenosis is often the result of the aging process, which over time causes the soft tissues and bones in the spine to harden or grow excessively.
Spinal stenosis occurs when part of your spine narrows, putting pressure on your spinal cord or nerves. That pressure can cause pain, numbness or weakness in your back, neck, shoulders or limbs.
Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow.
Aortic stenosis (AS) is narrowing of the aortic valve obstructing blood flow from the left ventricle to the ascending aorta during systole.
Mitral stenosis prevents the valve from opening properly. This prevents proper blood flow from moving between the left atrium (upper chamber of the heart) and ventricle (lower chamber of the heart).
Spinal stenosis is a narrowing of the lumbar (back) or cervical (neck) spinal canal, which causes compression of the nerve roots.

Aortic stenosis - or aortic valve stenosis - is a condition in which the aortic valve narrows. This narrowing prevents the valve from opening fully, which obstructs blood flow from your heart into the aorta and onward to the rest of your body.
Aortic stenosis may be present from birth (congenital), or it may develop later in life (acquired). Children with aortic stenosis may have other congenital conditions.
Spinal stenosis is a condition in which the spinal canal narrows and pinches the nerves, resulting in back and leg pain.
Mitral stenosis is a narrowing or obstruction of the opening of the mitral valve, which separates the upper (left arium) and lower chamber (left ventricle) on the left side of the heart.
Aortic Stenosis (AS) is the constriction of the aortic valve of the heart - the valve that regulates the blood being pumped out by the heart and stops it from flowing back into the left ventricle of heart.

Pyloric stenosis is about four times more common in boys than in girls, particularly in first-borns. It's less likely to develop in babies who are breastfed.
Symptoms of pyloric stenosis ...
Aortic valve stenosis can occur because of a birth defect in the formation of the valve. Calcium deposits may form on the valve with aging, causing the valve to become stiff and narrow. Stenosis can also occur as a result of rheumatic fever.
Renal artery stenosis (RAS) is the narrowing of one or both arteries that carry blood to the two kidneys. "Renal" means "kidney" and "stenosis" means "narrowing." RAS can cause high blood pressure and reduce kidney function.
Aortic valve stenosis means that this valve has narrowed, and it can't open all the way. The heart has to work harder to pump blood through the smaller opening. The heart can do this for many years, but over time it gets worn out.

Supravalvar aortic stenosis (usually membranous) sometimes associated with pulmonary valvular or peripheral arterial stenosis but with normal facies and mentality; autosomal dominant inheritance.

Lumbar spinal canal stenosis is not the same as a ruptured disk. A ruptured or "herniated" disk usually pinches 1 or 2 nerves at a time. The pain caused by a ruptured disk in the lumbar spine is usually easy to diagnose and is known as sciatica.

This condition is called dacryostenosis or congenital (present at birth) lacrimal duct obstruction. Tears help clean and lubricate the eye and are produced in the lacrimal gland located under the bone of the eyebrow.

The narrowing or constriction of a blood vessel or valve in the heart.
Cardiomyopathy

stenosis (narrowing) - if the aortic valve becomes narrowed and obstructs the blood flowing through it, or
regurgitation (leaking) - if the aortic valve leaks and blood flows back through the it into the left ventricle.
stenosis (or narrowing of the valve)
The valve(s) opening becomes narrowed or valves become damaged or scarred (stiff), inhibiting the flow of blood out of the ventricles or atria.

Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located within the backbone. It is a small space that holds the nerve roots and spinal cord.
Spinal stenosis - a condition that causes a narrowing of the canal that holds the spinal cord and many nerve roots. This may cause pressure on the sciatic nerve.
