This is either a open or closed valvotomy:

  • mobile valve in less developed countries and during pregnancy - use closed mitral valvotomy (inserting dilator through a beating left ventricle via left thoracotomy)

  • mobile valve - method of choice - open mitral valvotomy with separation of fused papillary muscles and chordae, mobilisation of posterior leaflet by division of secondary chordae and correction of any mitral regurgitation by inserting a valvoplasty ring
