Minimally invasive surgery for mitral stenosis mainly refers to percutaneous balloon mitral stenoplasty. Percutaneous balloon mitral stenosis angioplasty works by utilizing the mechanical force of balloon expansion to separate the junction of the adherent mitral valve leaflets in order to improve mitral stenosis. In young female patients, treatment with percutaneous balloon mitral stenosis angioplasty avoids the need to take medications, thus ensuring a smooth pregnancy and delivery process in pregnant women. Percutaneous balloon mitral valvuloplasty requires that the mitral valve itself be relatively flexible. Minimally invasive surgical treatment of mitral stenosis is not possible if the mitral valve shows significant calcification. It is recommended that patients with mitral stenosis go to a regular hospital in time and standardize their treatment under the guidance of a doctor to avoid delays.
