Mitral and tricuspid regurgitation is mainly seen in mitral and tricuspid valve insufficiency, and its symptoms include those related to the original disease and those related to the phenomenon of heart failure caused by valve insufficiency. In mitral valve insufficiency, the symptoms may be asymptomatic in the early stages and progress rapidly if heart failure occurs. Mild closure insufficiency is associated with only mild discomfort, while severe closure insufficiency may be associated with exertional dyspnea, telangiectatic breathing, acute pulmonary edema, and may be associated with cough, sputum, and hemoptysis. In advanced right heart failure, stasis of the body circulation may occur, with symptoms such as edema, pleural fluid, and ascites. In tricuspid valve insufficiency, in combination with pulmonary hypertension, symptoms of reduced cardiac output, such as weakness and reduced exercise, may be manifested. In addition, there are symptoms associated with stasis of the body circulation, such as edema of the extremities, which can gradually spread upward to the whole body.
