The mitral valve is the most commonly affected valve in chronic rheumatic valvular heart disease. The

mitral valve is located between the left atrium and the left ventricle, and its unique anatomical position and structure make it more susceptible to rheumatic fever and other factors. During rheumatic disease, the mitral valve leaflets and chordae tendineae are prone to inflammation, fibrosis and deformation. At the

same time, the left atrium receives blood from pulmonary veins and then enters the left ventricle through the mitral valve. Long-term blood flow shock and rheumatic injury cause thickening, adhesion and even stenosis and insufficiency of the mitral valve, which seriously affects the normal function of the heart. In

addition, in patients with chronic rheumatic valvular heart disease, the mitral valve is more affected than other valves. This may be related to the key role of the mitral valve in the heart circulation and its relatively complex structure. When the mitral valve is diseased, it will cause a series of cardiac dysfunction and clinical symptoms.
