[Mitral valve prosthesis with preservation of the chordae and papillary muscles in patients with mitral insufficiency].
Mitral valve (MV) prosthetics was performed in 14 patients in its insufficiency. In MV replacement the chordopapillary apparatus (CPA) of the posterior cusp was left intact. The EMIKS or LIKS disk prosthesis was implanted in most cases (6 and 6 patients, respectively), the biological BAKS prosthesis was implanted in 2 patient. Orientation of the large semicircumference in the direction of the anterior or posterior commissure was the optimal orientation for the disk prostheses. Measurement of the parameters of hemodynamics on the operating table showed that reduction of the rigidity of the left-ventricular myocardium and the increase of the stroke index in patients with an intact chordopapillary apparatus of the posterior cusp differed significantly from those in patients with completely excised MV. Preservation of the CPA during MV replacement in patients with mitral insufficiency leads to reduction of the rigidity of the left-ventricular myocardium and improvement of its function immediately on the operating table.
