The valve-preserving operations on a chordo-papillary continuum in a mitral valve prosthesis

Keywords: mitral valve failure; prosthesis of a mitral valve; remote period of rhythm; preservation of a chordo-papillary continuum.

Abstract

Objective. Studying of morphometric indices and contractility of left ventricle in various variants of preservation of chordo-papillary continuum in late period after the mitral valve prosthesis.

Materials and methods. Analysis in 634 patients with isolated mitral valve failure, who were surgically treated from Sept. 1 2005 till Jan. 1 2007, was conducted. While the mitral valve prosthesis the chordo-papillary continuum was conducted, using preservation of the mitral valve posterior flap (41 patients) and simultaneous translocations of chordo-papillary muscles of anterior flap and preservation of posterior flap of a mitral valve (57 patients).

Results. While comparing morphometric indices of left ventricle in left ventriculomegaly on a hospital stage and in late postoperative period when complete excision of a mitral valve in its prosthesis was performed, and when posterior flap was preserved, and simultaneously the posterior and anterior mitral valve flaps the improvement of the indices was observed, as well as normalization of a contractile function of left ventricle if a subvalvular space is preserved.

Conclusion. Preservation of chordo-papillary continuum while performing the mitral valve prosthesis improves morphometric indices and contractility of left ventricle on a hospital stage and in late follow-up period.
