Mitral stenosis

Mitral stenosis is a heart valve or cusp defect that narrows the opening in the heart located between the right atrium and right ventricle. Usually the mitral valve closes more tightly in the middle, which causes a narrowing of the opening. As a result of this, the chamber into which venous blood flows - the right atrium - cannot freely expand and fill with the blood necessary for the body's circulation. This makes it difficult for normal blood flow. The incidence of mitral stenosis is 9-12% in the world. This defect is associated with a violation of the structure and shape of the mitral valve leaflets. Violation of the leaflet structure is the most common cause of myocardial stenosis. Severe deformation of the semilunar valve cusps leads to a reduction in throughput and subvalvular space and, as a consequence, to the development of pulmonary valve insufficiency. Symptoms of mitral valve dysfunction include shortness of breath, rough noise in the chest, and rapid pulse. To clarify the diagnosis, ultrasound and electrocardiography are prescribed. The results of the study allow us to select the most effective treatment method. The diagnosis of mitral stenosis is based on clinical indicators and echocardiography data. Insufficiency occurs when the normal size of the valve decreases with the addition of systolic murmur. The disease progresses in waves, manifesting itself in attacks of intensification of the disease with pronounced cardiac symptoms. Mitral stenosis is often caused by damage to valve collagen. Sometimes the cause of a stenotic valve artery defect cannot be determined. Surgical treatment of mitritis stenosis is symptomatic. Even in mild cases, timely and properly treated stenting allows a person to maintain a satisfactory quality of life for many years.
