Tricuspid regurgitation is rare in clinical practice, while mitral regurgitation is common in clinical practice. Valve regurgitation signals valve closure insufficiency, which occurs for the following reasons: a. Elderly valvular disease, which is often due to valve aging and stiffness causing valve closure insufficiency and regurgitation. Second, long-term myocardial ischemia can not be effectively treated, the valve ischemic fibrosis, calcification and other causes of valve closure, regurgitation. Rheumatic heart valve disease, rheumatism triggered by the inflammatory reaction involving the valve, resulting in valve closure insufficiency, regurgitation. At present, the incidence of elderly valve disease and ischemic valve injury is higher, the incidence of rheumatic heart valve injury is getting lower and lower, coronary heart disease is caused by ischemic valve closure insufficiency, causing valve regurgitation is one of the main causes of the disease. Active treatment of coronary heart disease, improve myocardial ischemia, prevent myocardial infarction, etc. can effectively protect the valve from damage and reduce the incidence of valve regurgitation. Valvular regurgitation can lead to hemodynamic disorders, heart failure in the late stage, poor prognosis, valve protection from the prevention of myocardial ischemia, stabilization of blood pressure, heart rate is the most important.
