Результаты протезирования митрального клапана с различной степенью сохранения подклапанных структур у детей

The article presents immediate and long-term results of mitral valve replacement in a pediatric group. The obtained data suggest that hospital mortality does not depend on the degree of preservation of subvalvular apparatus. Factors associated with mortality were young age and low weight, as well as higher NYHA functional class of chronic heart failure before surgery. Neither of groups showed significant advantages in the immediate postoperative period. However, the group with subvalvular apparatus required lower cumulative doses of inotropic drugs. Remote mortality rate was higher in the group with complete excision of subvalvular apparatus.
