Replacement of mitral valve posterior chordae tendineae with expanded polytetrafluoroethylene suture: a finite element study.

Abstract

BACKGROUND AND AIMS Expanded polytetrafluoroethylene (ePTFE) suture has been used clinically for replacement of ruptured mitral valve chordae tendineae. The purpose of this study was to assess mitral valve function after posterior chordal replacement with ePTFE suture. METHODS A three-dimensional finite element computer model of the mitral valve was used… (More)
