Does interventional therapy for mitral stenosis require repeated surgery?

If the mitral stenosis is mild, the risk and trauma of interventional treatment are small, and the patient's cardiac function and discomfort can be improved. Usually, repeated surgery is not required. If the mitral stenosis is severe, the risk of surgery will increase, and the disease will not be significantly relieved through single interventional treatment. At this time, repeated interventional surgery is usually required to obtain a good prognosis.
