[The mitral valve dysplasia in adults: the choice of surgical tactics].

ABSTRACT

Early and long-term results of hereditary mitral valve dysplasia surgical treatment were obtained in 203 patients. All patients were divided in 2 groups 73 (36%) patients after valve-preserving operations and 130 patients after universal chorda-preserving valve prosthetics. The choice of treatment modality depended on the type of anatomical changes and overall surgical volume. Hospital lethality rate was 2.46%. Surgery led to satisfactory functional results, thus, 83.3% of the operated patients have I-II NYHA functional class. Analysis of the own experience allowed to mark out factors, contraindicating the durable plastic mitral valve.
