The aorta is the main artery carrying blood out of the heart. When blood leaves the heart, it flows through the aortic valve, into the aorta. In aortic stenosis, the aortic valve does not open fully. This decreases blood flow from the heart.
Aortic valve stenosis; Left ventricular outflow tract obstruction; Rheumatic aortic stenosis; Calcium aortic stenosis
Causes, incidence, and risk factors
As the aortic valve becomes more narrow, the pressure increases inside the left heart ventricle. This causes the left heart ventricle to become thicker, which decreases blood flow and can lead to chest pain. As the pressure continues to rise, blood may back up into the lungs, and you may feel short of breath. Severe forms of aortic stenosis prevent enough blood from reaching the brain and rest of the body. This can cause light-headedness and fainting.
Aortic stenosis may be present from birth (congenital), or it may develop later ...
Even back pain caused by a spondylolisthesis and lumbar stenosis can be treated with physical therapy. Because spondylolisthesis and lumbar stenosis can cause nerve damage, surgery is the natural knee-jerk treatment option that people think about. Of course, surgical spinal fusion is the best option to stabilize the spine if the nerves are severely damaged and in jeopardy of further damage. But, what about a low grade spondylolisthesis and mild stenosis? Can surgery be avoided? Absolutely, the body is able to compensate for the misalignment of the passive, spinal structures with optimal functioning of the active, stabilizing muscles. That's right; bones, ligaments, and cartilage are passive structures that sometimes fail; thus, the muscles and nerves which actively control the muscles can compensate for the problem. The spine has two systems, the passive and the active system, which can balance each other out. This redundancy allows for one system to compensate for problems in the oth...
Definition Meatal stenosis is a narrowing of the opening of the urethra, the tube through which urine leaves the body. Alternative Names Urethral meatal stenosis Causes, incidence, and risk factors Meatal stenosis can affect both males and females, but it is more common in males. In males, it is often caused by swelling and irritation (inflammation) after a newborn is circumcised . This leads to abnormal tissue growth and scarring across the opening of the urethra. The problem is usually not found until the child is toilet trained. In females, this condition is present at birth (congenital). Although less common, metal stenosis may also affect adult women. Risks include: Having multiple endoscopic procedures ( cystoscopy ) Severe, long-term atrophic vaginitis
