Insufficiency of the aortal valve

Insufficiency of the aortal valve develops because of disturbance of functions of the aortal valve. Недостаточность аортального клапана - порок сердца

In a normality the aortal valve works as gate in one party. When it opens, blood from a left ventricle which is the main pumping heart camera, is pushed out in an aorta, the large artery departing from heart. From an aorta the blood containing oxygen gets to all organism on the branching-off arteries, thereby feeding an organism. While heart is on vacation between reductions, the aortal valve is closed thanks to what blood is not returned to heart.

At insufficiency of the aortal valve it is not closed completely therefore during each reduction of heart a small amount of blood which was pushed out in an aorta via the damaged valve gets back to a left ventricle. This process is called regurgitation. Because of it the insufficient amount of blood therefore heart should work strenuously gets to an organism to compensate shortage.

Depending on that, regurgitation in a left ventricle is how long, three degrees of insufficiency of the aortal valve are allocated:

• 1 degree of insufficiency of the aortal valve (insignificant) – is less than 5 millimeters from aorta valve shutters;

• The 2nd degree of insufficiency of the aortal valve (average) – 5-10 millimeters from aorta valve shutters;

• The 3rd degree of insufficiency of the aortal valve (expressed) – is more than 10 millimeters from aorta valve shutters.

Reasons of insufficiency of the aortal valve

Any state which causes damage of the valve of an aorta can become the reason of this disease. Most often it:

• inborn defect of the valve of an aorta;

• wear of the aortal valve with age;

• fever of rheumatic character;

• endocarditis;

• increase in an aorta because of high arterial pressure;

• atherosclerosis;

• radiation therapy of bodies of a thorax.

Seldom insufficiency of the aortal valve can be caused:

• Marfan's syndrome (disease of connecting fabric of system character);

• syphilis;

• some autoimmune diseases;

• ankylosing spondylitis.

Sudden insufficiency of the aortal valve can arise because of:

• an endocarditis (hit of an infection in heart);

• stratifications of an aorta (separation in an aorta of an inside layer from an average);

• problems with the fitted a prosthesis aorta valve.

Symptoms of insufficiency of the aortal valve

Замена клапана - хирургический способ лечения недостаточности аортального клапана At initial stages, as a rule, no symptoms are observed. But over time, when because of a reduced blood flow heart strenuously works and the left ventricle increases, there can be following symptoms:

• general weak state;

• arrhythmia (disturbance of a heart rhythm);

• an asthma, especially at exercise stresses;

• stenocardia, pain in a thorax which often appear at loadings;

• heartbeat, unpleasant feeling of the wrong and accelerated heart rhythm;

• to a syncope (loss of consciousness).

Treatment of insufficiency of the aortal valve

Treatment of insufficiency of the aortal valve is defined by the reasons and symptoms of a disease.

Often, if chronic insufficiency was diagnosed for the first time, special treatment it is not carried out. For monitoring a state it is necessary to visit the doctor. In certain cases, if there is reduced arterial pressure, some drugs can be used.

If insufficiency of the aortal valve is observed already throughout a long time, there were symptoms or the left ventricle lost the sokratitelny abilities, make surgical replacement of the valve.
