Examples of stenosis in the following topics:
-
- Pyloric stenosis (infantile hypertrophic pyloric stenosis) causes severe projectile non-bilious vomiting in the first few months of life.
- Pyloric stenosis (or infantile hypertrophic pyloric stenosis) is a condition that causes severe projectile non-bilious vomiting in the first few months of life.
- Pyloric stenosis also occurs in adults where the cause is usually a narrowed pylorus due to scarring from chronic peptic ulceration.
- Most cases of pyloric stenosis are diagnosed/confirmed with ultrasound, if available.
- The danger of pyloric stenosis comes from the dehydration and electrolyte disturbance rather than the underlying problem itself.
-
- ., one of the leaflets of the valve is too thick, misshaped, or doesn't separate from another leaflet), or the vessel above or below the valve being deformed in such a way as to prevent the proper flow of blood, the term pulmonary valve stenosis is used.
- Heart valve dysplasia is an error in the development of any of the heart valves, and a common cause of congenital heart defects in humans as well as animals; tetralogy of Fallot is a congenital heart defect with four abnormalities, one of which is stenosis of the pulmonary valve.
- The center of the image shows an aortic valve with severe stenosis due to rheumatic heart disease.
-
- Anatomical sources of heart murmurs include stenosis of the bicuspid aortic valve which tends to appear between 40 and 70 years of age, and stenosis of the tricuspid aortic valve where symptoms more likely to appear after 80 years of age.
- Hypertrophic subaortic stenosis may also cause heart murmur, with symptoms consisting of a harsh murmur in mid-systole, often accompanied by Brisk Bifid Carotid upstroke.
-
- This may cause a valve prolapse, adhesion of the adjacent cusps, of these valves, and occlusion of the flow tracts of blood through the heart, which causes disease known as valve stenosis.
-
- Among the diseases that can be caused by smoking are vascular stenosis, lung cancer, heart attacks, and chronic obstructive pulmonary disease.
-
- Non-physiological flow conditions (especially high values of shear stress) caused by arterial stenosis or artificial devices (e.g. mechanical heart valves or blood pumps) can also lead to platelet activation.
-
- Murmurs may also be called by valve stenosis (improper opening) and cardiac shunts, a severe condition in which a defect in the septum allows blood to flow between both sides of the heart.
-
- Heart murmurs may indicate the presence of valvular heart disease, either as a cause (e.g. aortic stenosis) or as a result (e.g., mitral regurgitation) of the heart failure.
-
- Aortic stenosis and aortic insufficiency, elevate left ventricular preload to the point where it becomes stiff and noncompliant, and is common in people 75 years of age or older.
