Surgical treatments for mitral stenosis include closed mitral valve junction dissection, percutaneous mitral balloon dilatation, and direct visualization, with results varying from patient to patient. 1. Closed mitral valvular junction dissection is usually performed through an incision in the left posterior lateral intercostal space or in the left anterior intercostal space. The pericardium is incised longitudinally in front of the phrenic nerve, and a mitral balloon dilator is inserted from the apical portion of the left ventricle, passed through the orifice, and dilated in stages. Due to the widespread use of percutaneous balloon dilatation, closed mitral junction dissection is rarely performed. 2. Percutaneous mitral balloon dilatation is performed by peripheral venous puncture, cannulation, and balloon catheterization through the femoral vein and inferior vena cava from the right atrium through the interatrial septum to reach the mitral valve area and dilate the mitral valve valve to achieve the purpose of lifting or reducing the resistance to blood flow in the left atrium. 3. The procedure is performed under extracorporeal circulation under direct visualization, with a median incision, incision of the left ventricle through the atrioventricular groove, exposure of the mitral valve, and incision of the fusion junction or excision of the entire valve for prosthetic valve replacement. If the diagnosis of mitral stenosis, should promptly seek medical treatment, under the guidance of the doctor, do not unauthorized treatment, so as not to delay the condition. Pay attention to rest on weekdays and avoid overwork.
