Background

Valves are membranous structures that can be opened and closed inside the organs of humans or some animals. Each individual has four valves in the heart, namely an aortic valve that joins the left ventricle and the aorta, a pulmonary valve that joins the right ventricle and the pulmonary arteries, a mitral valve that joins the left atrium and the left ventricle, and a tricuspid valve that joins the right atrium and the right ventricle, all of which act as one-way valves that allow blood to flow only in one direction and not in the other. Multiple causes can lead to valve damage, early stage valve pathological changes have no obvious symptoms, symptoms such as dyspnea (labored dyspnea, paroxysmal nocturnal dyspnea, acute pulmonary edema), cough, expectoration, hemoptysis, listlessness, cyanosis and the like can appear until left heart failure, symptoms such as jugular vein anger, liver swelling with tenderness, lower limb concave edema and the like can appear when right heart failure, and ascites and cardiogenic cirrhosis can occur at the late stage.
