Aortic valve insufficiency
Aortic valve insufficiency develops due to dysfunction of the aortic valve.
In normal aortic valve works as a gate to one side. When it opens, the blood from the left ventricle, which is the main pumping chamber of the heart, is pushed into the aorta, a major artery, extending from the heart. From the aorta contains oxygenated blood gets into the whole body of branching arteries, thereby nourishing the body. While the heart is at rest between beats, the aortic valve is closed, so that the blood returns to the heart.
When aortic valve does not close it completely, so during each contraction of the heart a small amount of blood, which the aorta vytalknulas through the damaged valve, falls back into the left ventricle. This process is called regurgitation. Because of this, the body gets enough blood, so the heart has to work hard to compensate for the shortfall.
Depending on how long regurgitation in the left ventricle, is allocated three degrees of aortic valve:
• 1 degree of aortic valve regurgitation (small) - less than 5 millimeters from the leaflets of the aortic valve;
• 2 degree of aortic valve regurgitation (average) - 5.10 millimeters from the leaflets of the aortic valve;
• 3 degree of aortic valve regurgitation (severe) - more than 10 millimeters from the aortic valve leaflets.
Causes of aortic valve regurgitation
The cause of the disease can be any condition that causes damage to the aortic valve. Most often it is:
• congenital aortic valve;
• deterioration of the aortic valve with age;
• rheumatic fever;
• increasing the aorta due to high blood pressure;
• radiation therapy of the chest.
Rarely, aortic valve regurgitation can cause:
• Marfan syndrome (a connective tissue disease systemic nature);
• Some autoimmune diseases;
• ankylosing spondylitis.
The sudden aortic insufficiency may occur due to:
• endocarditis (infection getting into the heart);
• aortic dissection (separation of the inner layer in the aorta from the middle);
• problems with prosthetic aortic valve.
Symptoms of aortic valve regurgitation
In the initial stages, usually no symptoms observed. But with time, when due to reduced blood flow and the heart works hard left ventricle increases, may experience the following symptoms:
• general weak state;
• arrhythmia (heart rhythm disturbance);
• shortness of breath, especially during physical exertion;
• angina, pain in the chest that often appear with loads;
• heartbeat, unpleasant feeling of wrong and accelerated heart rate;
• syncope (fainting).
Treatment of aortic valve regurgitation
Treatment of aortic valve determines the cause and symptoms of the disease.
Often, when first diagnosed with chronic insufficiency, special treatment is not carried out. To monitor the status you should visit a doctor. In some cases, if there is a decrease in blood pressure, certain drugs can be used.
If the aortic valve insufficiency has been observed for a long time, any symptoms or left ventricular contractile lost their ability to carry out surgical valve replacement.
