In article seven-year experience of treatment 126 sick mitral heart diseases to which have been implanted domestic monofolding the MIKS and folding MEDING-2 and ROSCARDIKS artificial mitral valve. At a comparative estimation of a haemodynamic efficiency and the analysis of frequency of occurrence of dysfunctions of the specified mechanical artificial valve it is revealed, that till three years the postimlantsperiod implant the MIKS and MEDING-2 possess advantage over ROSCARDIKS on haemodynamic properties, despite priority ROSCARDIKS on a standard size. It is shown, that initially low diastolic pressure gradient on mitral artificial valve and initially big area effective apertures mitral artificial valve have crucial importance in aspect of preventive maintenance of formation valve complications and reduction of number of repeated operations by open heart.
