This study sought to identify the mitral valve (MV) parameters measured by three\u2010dimensional transesophageal echocardiography (3D\u2010TEE) and MV leaflet features that predict residual mitral regurgitation (MR) after TMVR in patients with FMR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive patients with FMR who underwent TMVR were classified into two groups based on the degree of residual MR just after TMVR:\u00a0&lt;\u00a02+ in the optimal MR reduction group and \u2265 2+ in the suboptimal MR reduction group. The two groups were compared with respect to 3D\u2010TEE parameters and the MV leaflet features, including the following parameters: stiffness, defined as a leaflet that remains at a fixed angle even during diastole, and thickness, measured in both clear and rough zones.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010four of 46 patients (74%) were classified as the optimal MR reduction group.
