The main methods of mitral stenosis treatment are as follows: 1. Allopathic treatment. If mitral stenosis is mild and not enough to cause clinical symptoms, attention to dynamic observation is sufficient. No special treatment is needed. If the mitral stenosis is moderate to severe, timely percutaneous balloon dilatation valvuloplasty is required. The degree of mitral stenosis can be corrected by prosthetic valve replacement or mitral valve dissection. 2, symptomatic treatment. As the disease progresses, especially into the mitral stenosis decompensation phase, it is likely that atrial fibrillation with rapid ventricular rate episodes, arrhythmias, pulmonary embolism, pulmonary edema, pulmonary stasis and other conditions. Therefore, timely treatment with medications such as nitroglycerin, expansion of coronary circulation, and reduction of cardiac load is required.
