Our retrospective analysis divided the patients with AFMR into two groups according to whether LAP was performed (LAP\u2009+\u2009group, <jats:italic>n<\/jats:italic>\u2009=\u20099; LAP\u2009\u2212\u2009group, <jats:italic>n<\/jats:italic>\u2009=\u200913). Mitral valve angle (MV angle) (horizontal inclination of mitral valve) was measured by pre- and post-operative computed tomography scan. Individuals with type II mitral regurgitation, left ventricular ejection fraction of\u2009&lt;\u200955%, males with left ventricular endo-diastolic dimension of\u2009&gt;\u200960\u00a0mm and females with\u2009&gt;\u200955\u00a0mm, aortic valve disease, mitral valve calcification, hypertrophic obstructive cardiomyopathy, and both \u201credo\u201d and emergency cases were excluded.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Result<\/jats:title>\n                <jats:p>Mitral valve replacement was performed in 6 patients and mitral ring annuloplasty in 16 cases. No recurrence of mitral regurgitation or structural valve deterioration occurred during the follow-up period. There were no hospital deaths; 3 deaths occurred during the follow-up period. Compared to the LAP\u2009\u2212\u2009group, the LAP\u2009+\u2009group demonstrated a significantly greater decrease of MV angle (16.6\u2009\u00b1\u20098.1\u00b0 vs. 1.2\u2009\u00b1\u20096.9\u00b0, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01) and left atrial dimension (18.4\u2009\u00b1\u20097.0\u00a0mm vs. 6.9\u2009\u00b1\u200914.6\u00a0mm, <jats:italic>p<\/jats:italic>\u2009=\u20090.02).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Surgical results of AFMR were satisfactory.
