Can Mitral Valve Replacement Be The First-line Intervention? - LVAD Implantation Alone Vs. Chordal Sparing Mitral Valve Replacement With Submitral Procedures For End-stage Heart Failure

Methods: Subjects were 26 patients who had refractory heart failure due to cardiomyopathy andmitral regurgitation (MR): 14 patients with more than moderate MR who had implantable LVAD and 12 patients with severe MR who were not candidates for heart transplantation and underwent chordal sparing MVR. MVR was conducted with a combination of papillary muscle approximation and suspension (papillary muscle tugging approximation), a new modification that we developed in 2015.
