- Aortic valve stenosis is narrowing of the aortic valve. Many things can narrow this passageway between your heart and aorta. Causes of aortic valve stenosis include: Congenital heart defect. The aortic valve consists of three tightly fitting, triangular-shaped flaps of tissue called leaflets.

stenosis an abnormal condition characterized by the constriction or narrowing of an opening or passageway in a body structure. The term is commonly used to describe heart valve and vessel abnormalities as well as narrowing of joint spaces, as in cervical stenosis. Kinds of stenosis include aortic stenosis and pyloric stenosis.

Stenosis A stenosis (/stəˈnoʊsɨs/ ; plural: stenoses, /stəˈnoʊˌsiːz/) (from Ancient Greek στένωσις, narrowing) is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).

Leaky Heart Valve Except the mitral valve, each valve typically has three flaps. The mitral valve has two flaps. Any of the four valves can become leaky. This means that just after the heart squeezes and pumps blood forward, some blood will leak backward through the valve. Leaking through the valve is also called valve regurgitation.ny of the four valves can become leaky. This means that just after the heart squeezes and pumps blood forward, some blood will leak backward through the valve. Leaking through the valve is also called valve regurgitation.

Mitral Valve Regurgitation: Treating a Leaky Valve If a valve doesn’t close properly, blood can leak back into the heart, which is called regurgitation. The mitral valve is especially susceptible to this problem. If the leak is minor, you might never know it because the valve can still accomplish its job.

Stenosis A stenosis (/stəˈnoʊsɨs/ ; plural: stenoses, /stəˈnoʊˌsiːz/) (from Ancient Greek στένωσις, narrowing) is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).tricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g., achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g., atherosclerosis).

Problem: Heart Valve Regurgitation Regurgitation is the name for leaking heart valves. Sometimes the condition is minor and may not require treatment, but other times valve regurgitation places a strain on the heart. It can cause the heart to work harder and it may not pump the same amount of blood. Regurgitation occurs when: Blood flows back through the valve as the leaflets are closing.

Aortic stenosis Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level.

Heart Valve Problems Damage to the four valves of the heart can occur as a result of defects from birth, heart disease or chronic conditions such as emphysema or high blood pressure. Valve damage comes in two forms: regurgitation and stenosis. Regurgitation occurs when the valves are unable to close fully, allowing blood to flow backward. damaged valve can have either or both defects. Because heart valve damage often develops slowly, symptoms often are not present or are vague, such as a general feeling of fatigue. There are a few symptoms specific to each type of damage to each valve. A doctor, however, should make the final diagnosis.

- 1 Pyloric stenosis-chronic inflammation in the lining of the stomach or duodenum caused by a peptic ulcer can result in a narrowing of the pylorus (small passage that links the stomach and the duodenum). 2  Pyloric stenosis is the narrowing of the pylorus.hen a peptic ulcer affects the stomach it is called a gastric ulcer, one in the duodenum is called a duodenal ulcer, while an esophageal ulcer is an ulcer in the esophagus. When the lining of these organs is corroded by acidic digestive juices secreted by stomach cells peptic ulcers can form.

Aortic calcification: An early sign of heart valve problems? Aortic valve calcification is a condition in which calcium deposits form on the aortic valve in the heart. These deposits can cause narrowing at the opening of the aortic valve.This narrowing can become severe enough to reduce blood flow through the aortic valve, a condition called aortic valve stenosis.ortic valve sclerosis — thickening and stiffness of the valve and mild aortic calcification — usually doesn't cause significant heart problems, but requires regular checkups to make sure your condition isn't worsening. If the valve becomes severely narrowed (stenotic), aortic valve replacement surgery may be necessary.

Heart Failure  In-Depth Report Aortic regurgitation is where blood leaks back through the aortic valve. This is because the valve does not close properly. With each heartbeat, more blood than usual enters the left ventricle and so it needs to work harder.Mild regurgitation may not cause symptoms.he aortic valve lies between the left ventricle and the aorta. When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This allows more blood into the ventricle, ready for the next heartbeat. Aortic regurgitation is sometimes called aortic incompetence or a leaky aortic valve.

Stenosis 1 Mitral valve stenosis, which is the thickening of the mitral valve (of the left heart), therefore causing narrowing.  Tricuspid valve stenosis, which is the thickening of the tricuspid valve (of the right heart), therefore causing narrowing.

- Mitral valve prolapse is a condition in which the two valve flaps of the mitral valve do not close smoothly or evenly. Mitral valve prolapse is also known as click-murmur syndrome, Barlow's syndrome or floppy valve syndrome.ymptoms, which in some cases may be related to leaking of the mitral valve, can include: 1  Chest pain (not caused by coronary artery disease or a heart attack). 2  Dizziness. 3  Fatigue. 4  Sensation of feeling the heart beat (palpitations). 5  Shortness of breath with activity or when lying flat (orthopnea).

Mitral valve prolapse Mitral valve prolapse is generally the most benign of the various types of heart murmurs and is probably genetic in origin. It is the most common valvular disorder in industrialized nations at the present, since the risk of heart murmurs from rheumatic fever has been reduced.here is at the same time less to it and more to it than at first appears. Mitral valve prolapse is named for a heart valve and is usually first diagnosed as a faint heart “click” or murmur, though it isn’t a form of “heart disease” in any conventional sense.

There are 4 Main Causes of Aortic Stenosis Age and aortic stenosis. Calcification 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.ortic 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.

- 1 Pulmonic stenosis (PS): narrowing of the pulmonic valve. 2  Subvalvular aortic stenosis (SAS): narrowing below the aortic valve. 3  Tricuspid valve dysplasia (TVD): malformation of the tricuspid valve. 4  Mitral Valve Disease: degeneration of the mitral valve leading to severe valve regurgitation (leak).

Aortic Valve Disease Aortic stenosis typically refers to obstruction of flow at the level of the aortic valve and does not include the subvalvular and supravalvular forms of this disease.

Narrowing Artery â Causes of Arterial Stenosis Any narrowing of an artery will hamper the flow of blood and depending on the extent of the narrowing, known as stenosis, the artery may be partially or completely occluded (blocked). Narrowing of an artery may not cause obvious signs and symptoms in the initial stages.

Foraminotomy â minimally invasive spine surgery for foraminal stenosis This narrow passageway is called the foramina. When the foramina becomes narrowed due to a bulging disc or other spine conditions, foraminal stenosis occurs. Foraminal stenosis literally means the narrowing of the foraminal spine.
