Diseases of the valves of the heart: aortic stenosis
Aortic stenosis is a very common valve disease in Western countries; men between 60 and 70 years of age are most affected
If not treated properly, the disease progresses to death, in about 50 percent of cases and 3 years after the onset of symptoms.
Aortic stenosis is the narrowing of the aortic valve, through which blood passes before going into the arterial system.
The obstruction will force the left ventricle to exert strain in pushing pressure, and this will lead to enlargement of the heart wall.
Symptoms of aortic stenosis, will vary depending on the severity of it
if there will be mild narrowing, there will be the presence of a heart murmur.
in advanced stages of stenosis, there will be wheezing, chest pain and sudden fainting.

The causes of aortic stenosis may be congenital when, it will be related to aortic bicuspidia
It may be acquired when, it will be related to rheumatic diseases triggered by bacterial infections that have not been properly treated, or it will be related to calcific degeneration linked to the normal aging process of the body; the latter is among the most frequent causes.
Echocardiography is the best test to diagnose valvulopathy; it will allow analysis of the size of the heart chambers, thickening of the heart muscle walls, and the variation of the valves and their respective opening and closing points, which will narrow in case of stenosis.
An electrocardiogram and chest X-ray will also allow you to check for the presence of the condition
If you will have severe aortic stenosis, the only effective option will be to undergo surgery; which may be either surgical replacement or percutaneous approach.
Minimally invasive techniques may also be used through the reduced chest incision and the use of the latest surgical prostheses that will see no need to apply stitches.
In the percutaneous approach, on the other hand, there will be no opening of the chest; the valve will be grafted through the femoral artery to the heart, where it will clearly be released.
This doctor will be used if the patient is at high risk for the normal mode of operation.
In order to prevent the occurrence of this disease, it is necessary to maintain a proper lifestyle, undergo periodic medical checkups especially with cardiologists in order to monitor heart muscle and vascular system.
Medications could also be prescribed, aimed at reducing the workload of the heart, lowering its rate, counteracting ventricular remodeling and hypertrophy, monitoring pressure without worsening the gradient at the valve level that will be affected by cardiac output and duration of diastole.
