Mild mitral insufficiency of the heart may present with exertional dyspnea or may be asymptomatic; mild tricuspid insufficiency is mostly asymptomatic. 1. Mild mitral valve insufficiency: in mild cases, exertional dyspnea may occur, or it may last a lifetime without symptoms. 2. Mild tricuspid valve insufficiency: simple tricuspid valve insufficiency is relatively rare, can be secondary to mitral valve insufficiency, usually without any symptoms, most often found during physical examination of the heart ultrasound. If mitral valve or tricuspid valve insufficiency is found, you should consult a doctor in time and follow the doctor’s instructions for treatment.
