Valved-conduit-on-valve implantation for physiologic total chordal preservation in rheumatic mitral valvulopathy

Abstract

Varied methods for total chordal preservation in mitral valve replacement (MVR) have been presented with significant long-term advantage. However, it is difficult to preserve whole the mitral apparatus in the case of rheumatic mitral valvulopathy. Previously, we reported a technique for redo MVR referred to as conduit-onvalve replacement with satisfactory result. Based on the same concept, a procedure wherein a valved conduit is implanted on the undisturbed mitral apparatus was developed for preserving the whole mitral apparatus in the most physiologic orientation with minimal technical demand.
