RESUMEN
Possibilities of application of the proposed procedure for intraoperative restoration of the sinus rhythm while the mitral valve prosthesis (MVP) were studied up. In 161 patients, suffering the isolated mitral valve failure stage IV, a surgical treatment was conducted in Department of surgical treatment of acquired heart failures. The left atrium plasty was conducted in 119 (73.9%) of them with the objective to reduce its size and eliminate the re-entry waves passability. Fragmentation in left atrium was conducted in lowradiofrequency regime of diathermy (25-35 W) in accordance to variant (cut and sew) of operations Maze - 3 and Maze - 4. On a hospital stage 3 patients died (hospital lethality 1.9%). MVP in combination with Maze operation in a lowradiofrequency regime have permitted to restore successfully a correct rhythm in 80.2% of patients on a hospital stage and to stabilize it during 1 year postoperatively.

Possibilities of the procedures conduction of the left atrium (LA) plasty in a mitral valve prosthesis (MVP) were studied. There were examined 553 patients, in whom surgical treatment in the clinic was conducted. In all the patients MVP was conducted for isolated mitral valve failure and dilatation of LA. In 371 patients (the main group) MVP and LA plasty were conducted, in 182 (control group)--LA was not corrected. Morphometric indices of left cardiac cameras, survival, stability of the operation good results in late terms have witnessed high efficiency of MVP with LA reduction in comparison with such in a control group. Late results of MVP in conjunction with LA reduction exceed such in a control group, witnessing expediency of the proposed methods of surgical treatment application.
