[Cardiac valves lesions and its correction in the heart myxoma]

The experience of surgical treatment of 34 patients, suffering the heart valves affection in cardiac myxoma (CM), was summarized. In 29 patients the affection of a mitral valve (MV) was noted and in 5--of a tricuspid one. Functional disorders of valves was observed in presence of a large, moving, frequently calcified CM owing high density. Radical reconstructive-restoration interventions were performed with artificial blood circulation. In 9 patients the MV prosthesis was performed, in 3--the tumor excision, affecting undervalvular apparatus and in 4--the MV plasty (annuloplication). The MV cuspids deformity was corrected in 8 patients and for the MV chords rupture in 1 patient the plasty was performed, using sectored resection. The MV cuspids implantation was done in 9 patients. Late follow-up results were studied up in 26 patients in terms from 2 mo to 20 years postoperatively. Good result was achieved in 18 patients, fair--in 5 and unsatisfactory--in 3. Thus, the presence of CM may be accompanied by necessity to correct the coexistent valve affection, what improves the operation result.
