What is the collapse of the mitral valve?
Mitral valve collapse is the most common problem of heart valve that affects between 4 and 18 percent of all people. The mitral valve collapse occurs when the valve between the left atrium of the heart and the left ventricle does not cover correctly and allows blood to flow back from the left ventricle to the left atrium. Backflow blood is referred to as regurgitation of mitral valves. The cause of the collapse of the mitral valve is unknown. In the body, blood with smooth oxygen enters the right atrium of the heart, passes through the tricuspide valve and into the right chamber. The blood is then pushed from the right ventricle into the lungs where it is oxygenated. Oxygen -rich blood returns to the heart through the left atrium, passes through the mitral valve into the left ventricle and then is forced throughout the body. Mitral and tricuspid valves are necessary in the previous existence of blood flow in the heart. Mitral valves may break in two ways: the valve gates can be longer and stronger than necessary, which prevents tight seals; or valve valves can be poor, stretch more than necessary andIt makes strong closure impossible.
Mitral valve collapse is originally diagnosed with listening to the heart with a stethoscope. The non -functional mitral valve creates a click when blood moves through it. Confirmation of the collapse of the mitral valve is sometimes performed using an echocardiogram or electrocardiogram. Sometimes there will be a stress test to ensure that the collapse of the mitral valve will not disrupt the exercise.
Most symptoms related to the collapse of the mitral valve are benign. People often does not even know that they have a valve defect. Other times, the symptoms are more serious and apparent. Mezi tyto příznaky patří palpitace srdce nebo arytmie, těžká regurgitace mitrální chlopně nebo srdeční infekce známé jako endokarditida.
Mitral valve collapse sometimes results in arrhythmia or irregularly slow or fast heart rhythms. If this problem is severe, beta is treated with blockers. Bett blockers are medicines that fromThey paint heart rate and reduce the vitality with which the heart beats.
When the collapse of the mitral valve causes severe regurgitation or back flow of blood in the heart, surgery may be required to prevent complications or heart failure. Surgery will either repair the existing valve or replace it. The malfunctioning mitral valve is repaired by the transformation or changing the valve change to close completely. If the valve cannot be repaired and should be removed, it can be replaced by a mechanical valve or a donated tissue valve.
endocarditis is an infection of endocardium or membrane tissue that lines the heart. Backflow blood that occurs in a non -functional mitral valve is the heart more susceptible to infection. To prevent endocarditis, antibiotics are often prescribed before surgery and before any dental procedures.
