Reduction of tethering distance by papillary muscle tugging approximation with mitral valve replacement for non-ischemic functional mitral regurgitation induces left ventricular reverse remodeling.

Takahiro Ishigaki, Satoru Wakasa, Yasushige Shingu, Yohei Ohkawa, Akira Yamada, Toshihisa Anzai, Yoshiro Matsui,

<h4>Background</h4>Functional mitral regurgitation (FMR) is caused by left ventricular (LV) remodeling and subsequent tethering of the mitral valve (MV). If LV remodeling is irreversibly advanced, it could not be attenuated by the MV procedure alone, although the additional subvalvular procedure could induce LV reverse remodeling by forcibly reducing MV tethering. ...
