Preservation of mitral chordae during MV replacement
Preservation of the left ventricular longitudinal function
January 25, 2021
In this patient undergoing mitral valve replacement with a mitral bioprosthesis, the mitral chordae are spared and reattached to the prosthetic annulus. This ensures that the continuity between the LV longitudinal fibers and the base of the heart is preserved.
(tt2857) MV chordae to the posterior leaflet are spared (Figure 2, thick white arrow) during MV replacement with bioprosthesis (thin white arrows point to the cusps of the mitral bioprosthesis), to preserve anatomical and functional continuity between the LV longitudinal fibers of the postero-medial papillary muscle and the mitral annulus. Preservation of LV longitudinal function is essential to preserve LV global function (ejection fraction) after mitral valve (replacement or repair) surgery.
