The treatment of mitral stenosis mainly includes medication and surgery. 1. Drug therapy: for mitral stenosis caused by rheumatic fever, benzylpenicillin can be used for a long time; for pulmonary stenosis caused by mitral stenosis, sodium intake should be limited, and diuretics can be used intermittently; for those who suffer from massive hemoptysis, sedatives can be used, as well as intravenous use of diuretics; patients with atrial fibrillation can be treated with deacetylline and diltiazem. 2. Surgery: For moderate to severe mitral stenosis, progressive aggravation of dyspnea or pulmonary hypertension, mechanical interventions are needed to relieve mitral stenosis and alleviate the symptoms; such as percutaneous balloon mitral valvuloplasty (only for patients with simple mitral stenosis), mitral valve detachment and prosthetic valve replacement. It is recommended that patients go to the hospital in time, complete the relevant examinations under the guidance of professional doctors, and receive standardized treatment.
