Overview Causes of mitral valve stenosis include: Rheumatic fever. A complication of strep throat, rheumatic fever can damage the mitral valve. Rheumatic fever is the most common cause of mitral valve stenosis. It can damage the mitral valve by causing the flaps to thicken or fuse. Signs and symptoms of mitral valve stenosis might not show up for years.

Aortic Valve Stenosis Symptoms, Treatment, Types & Surgery In adults, three conditions are known to cause aortic stenosis. 1  Progressive wear and tear of a bicuspid valve present since birth (congenital).  Wear and tear of the aortic valve in the elderly.

Spinal Stenosis The most common cause of spinal stenosis is aging. Degenerative processes occur throughout the body as it ages. Tissues in the spine may start to thicken, and bones may get bigger, compressing the nerves. Conditions like osteoarthritis and rheumatoid arthritis may also contribute to spinal stenosis.

Aortic Valve Stenosis Symptoms, Treatment, Types & Surgery In adults, three conditions are known to cause aortic stenosis. 1  Progressive wear and tear of a bicuspid valve present since birth (congenital). 2  Wear and tear of the aortic valve in the elderly. 3  Scarring of the aortic valve due to rheumatic fever as a child or young adult.ver time, excessive wear and tear leads to calcification, scarring, and reduced mobility of the valve leaflets. About 10% of bicuspid valves become significantly narrowed, resulting in the symptoms and heart problems of aortic stenosis.

Cauda equina syndrome Spinal stenosis. CES can be caused by lumbar spinal stenosis, which is when the diameter of the spinal canal narrows. This could be the result of a degenerative process of the spine (such as osteoarthritis) or a developmental defect which is present at birth. In the most severe cases of spondylolisthesis cauda equina syndrome can result.

Problem: Heart Valve Stenosis About Valve Stenosis Stenosis is the term for a valve that doesn’t open properly. The flaps of a valve thicken, stiffen, or fuse together. As a result, the valve cannot fully open. Thus, the heart has to work harder to pump blood through the valve, and the body may suffer from a reduced supply of oxygen.Causes of Valve Stenosis Stenosis can be caused by age or by a malformed valve called a bicuspid valve.hus, the heart has to work harder to pump blood through the valve, and the body may suffer from a reduced supply of oxygen.

- The most common cause of lumbar spinal stenosis is degenerative arthritis and degenerative disc disease. As with other joints in the body, arthritis commonly occurs in the spine as part of the normal aging process and as a result of osteoarthritis.ach of these processes can reduce the normal space available for the nerves in the spinal canal and result in direct pressure on nerve tissues to cause the symptoms of lumbar spinal stenosis. Lumbar spinal stenosis can also be caused by other conditions that decrease the space of the spinal canal or vertebral foramen.

Overview The two main causes of renal artery stenosis include: 1  Atherosclerosis of the renal arteries. Atherosclerosis is the buildup of fats, cholesterol and other substances (plaques) in and on your artery walls. 2  Fibromuscular dysplasia. In fibromuscular dysplasia, the muscle in the artery wall grows abnormally.

Renal Artery Stenosis More rarely, renal artery stenosis can be caused by a condition called fibromuscular dyplasia, in which the cells in the walls of the arteries undergo abnormal growth. More commonly seen in women and younger people, fibromuscular dyplasia is potentially curable.

Horn Noise FAQ Noise in our environment can be described by three characteristics -- loudness, pitch, and time variation. Loudness is the intensity of sound or sound energy, and is described in terms of decibels (dB). For example, the louder the sound, the greater the decibel value. Pitch is the note or wavelength of the sound.

Aortic Valve Stenosis Symptoms, Treatment, Types & Surgery Aortic stenosis is abnormal narrowing of the aortic valve. A number of conditions cause disease resulting in narrowing of the aortic valve. When the degree of narrowing becomes significant enough to impede the flow of blood from the left ventricle to the arteries, heart problems develop. The heart is a muscular pump with four chambers and four heart valves.

There are 4 Main Causes of Aortic Stenosis Aortic Stenosis Symptoms. Aortic stenosis is the narrowing of the aortic valve, which limits the aortic valve leaflet's ability to fully open and close. Valve leaflets are flaps of tissue that open and close to regulate the one-way flow of blood through the aortic valve.alcification is the process that refers to the build-up of calcium on the heart's valves. In elderly patients, aortic stenosis is sometimes caused by the build-up of calcium (mineral deposits) on the aortic valve’s leaflets. Over time the leaflets become stiff, reducing their ability to fully open and close.

spinal stenosis spinal stenosis, narrowing of the vertebral canal, nerve root canals, or intervertebral foramina of the lumbar spine, caused by encroachment of bone on the space. Symptoms are caused by compression of the cauda equina and include pain, paresthesias, and neurogenic claudication.

- Narrowed spinal canal (stenosis) and sciatica. A common cause of a narrowed spinal canal is arthritis of the spine. Pain may begin in your back and hip, then later extend down into your leg. Rest is often the cure for other pains of the leg, but not this one.

What Is Spinal Stenosis? For most people, the stenosis results from changes because of arthritis. The spinal canal may narrow. The open spaces between the vertebrae may start to get smaller. The tightness can pinch the spinal cord or the nerves around it, causing pain, tingling, or numbness in your legs, arms, or torso.

Spinal Stenosis Spinal stenosis fundamentals. With age, the spinal canal – located in the lower back – can narrow, resulting in spinal stenosis. The narrowing process, which is gradual, reduces the space available for the spinal cord and nerves. If only a small amount of spinal narrowing occurs, no pain will result. Spinal stenosis may lead to leg pain, numbness, and/or tingling.

Spinal stenosis Spinal stenosis is a narrowing of the open spaces within your spine, which can put pressure on your spinal cord and the nerves that travel through the spine to your arms and legs. Spinal stenosis occurs most often in the lower back and the neck. While spinal stenosis may cause no signs or symptoms in some people, other people may experience pain, tingling, numbness, muscle weakness, and problems with normal bladder or bowel function. Spinal stenosis is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis. In severe cases of spinal stenosis, doctors may recommend surgery to create additional space for the spinal cord or nerves.
