Fifteen patients with moderate to severe MR were separately analyzed to determine whether the severity of MR influences the geometric change in <jats:styled-content style=\"fixed-case\">AMC<\/jats:styled-content>. Echocardiographic examinations were performed pre\u2010 and post\u2010<jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content>, and the studied parameters were obtained using Siemens Auto Valve Analysis software. The effective mitral regurgitant orifice area, left ventricular ejection fraction (<jats:styled-content style=\"fixed-case\">LVEF<\/jats:styled-content>), end\u2010diastolic volume (<jats:styled-content style=\"fixed-case\">EDV<\/jats:styled-content>), and end\u2010systolic volume (<jats:styled-content style=\"fixed-case\">ESV<\/jats:styled-content>) were measured pre\u2010 and post\u2010<jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content> using Philips <jats:styled-content style=\"fixed-case\">QLAB<\/jats:styled-content> software. Ischemic MR, <jats:styled-content style=\"fixed-case\">EDV<\/jats:styled-content>, and <jats:styled-content style=\"fixed-case\">ESV<\/jats:styled-content> significantly decreased (all P\u00a0&lt;\u00a00.05) and <jats:styled-content style=\"fixed-case\">LVEF<\/jats:styled-content> significantly improved (P\u00a0&lt;\u00a00.05) after <jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content>.

Patients with moderate to severe MR exhibited the same results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The results of this study show that <jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content> does not cause an acute change in the geometry of <jats:styled-content style=\"fixed-case\">AMC<\/jats:styled-content>. Improved left ventricular function might increase the closing force of the MV, leading to decreased MR after <jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content> alone. MR significantly improved after <jats:styled-content style=\"fixed-case\">CABG<\/jats:styled-content> alone without MV treatment in the present study.
