[Comparative study of the results of prosthesis implantation and reconstructive surgery of the mitral valve in congenital insufficiency].

In 23 of 154 patients with congenital mitral valve (MV) insufficiency the MV prosthetics was conducted, and in 23-valve-preserving reconstructive operation. Operative procedures were depicted, early and late follow-up results were analyzed. After the valve-preserving operation conduction hospital lethality was 8.7%, and after the (MV) prosthetics-34.8%. In the late follow-up period after (MV) plastic reconstruction conduction good results were noted in 17 patients, satisfactory-in 1, reoperation was performed in 3 (13%). Application of soft synthetic ring, preventing the dilation of the valve fibrotic ring, may to lower the frequency of reoperation conduction. Plastic correction of the CMVI permits to eliminate the basic haemodynamical disorders and to avoid or postpone the MV prosthetics conduction, what especially important in children.
