Technique of mitral valve replacement with the Monostrut prosthesis preserving the posterior leaflet.

BACKGROUND AND AIM OF THE STUDY

Techniques of mitral valve replacement with leaflet and chordal preservation normally involve the use of a bioprosthesis or bileaflet valve to reduce the risk of obstruction of the prosthesis by the retained subvalvular apparatus.

METHODS

The technique of mitral valve replacement with the Monostrut prosthesis and with preservation of the posterior leaflet is described. The stitches are placed in such a manner that the posterior leaflet is folded under the posterior aspect of the prosthetic ring.

RESULTS AND CONCLUSIONS

The technique allows safe implantation of the Monostrut valve. The excellent performance of this prosthesis can be therefore combined with the beneficial effects of chordal preservation on left ventricular function.
