Abstract

Background. Studying the results of the mitral valve repair(MVR) by creating multiple neochords of polytetrafluoroethylene sutures (PTFE).

Materials and Methods. From November 2010 to November 2017, the Department of reconstructive surgery of A.N. Bakoulev Scientific Center for Cardiovascular Surgery performed correction of mitral valve prolapse by creating multiple artificial chords in 76 patients with severe degenerative disease. There were 44 men and 32 women whose mean age was 45,7 ± 12.5 years ranging from 18–76. All patients had significant mitral valve regurgitation, and the mean severity was 3.5 ± 0.4. Isolated prolapse of the anterior leaflet was present in 17.6% of patients, isolated posterior leaflet prolapse was present in 29.5% of patients, and bileaflet prolapse was present in 52.9% of patients. Prolapse was corrected by creating 4 to 16 neochords of polytetrafluoroethylene sutures.

Results. Hospital mortality was absent. In 4 (5.3%) patients in the early postoperative period was noted moderate heart failure. In some patients were observed characteristic for the correction of mitral regurgitation, a moderate decrease in total ejection fraction of the left ventricle (64,9% ± of 6.48% - before surgery, 60.8 ± 6.12% after the operation). In the early postoperative period mitral regurgitation beat the minimum (37– 48.7%) – or small. (21 –27.6%). Severe complications during follow up in patients were noted.

Conclusions. The creation of multiple neochordae allows to correct mitral regurgitation in severe degenerative disease, with the maximum and reliable restoration of the anatomical and physiological characteristics of the mitral valve
