Closed mitral valve separation

According to the five-level classification of cardiac function, the indications for closed mitral valve separation are selected as follows: Patients in level 0 need not consider surgical treatment. In primary patients, surgery is generally not required. However, x-ray examination showed more obvious pulmonary congestion and enlarged heart, or ECG showed more obvious right ventricular hypertrophy. If mitral valve balloon dilatation fails, surgical treatment can be considered. Patients with secondary and tertiary disease have obvious symptoms of mitral stenosis. If balloon dilatation fails without surgical contraindications, they are both suitable for surgical treatment. Grade 4 patients have significant congestive heart failure and complete loss of labor. Such patients urgently need surgical treatment; however, they must undergo medical treatment before surgery and heart failure can be controlled before surgery.
