The 1\u2010, 3\u2010, and 5\u2010year survival rates for patients with MVr were 96.6%, 91.8%, and 77.4%, respectively, which were significantly higher than that of medical group: 81.2%, 71.9%, and 65.1%, respectively (HR, 0.32; 95% CI, 0.12\u20130.87; <jats:italic>p<\/jats:italic>\u2009=\u2009.03).
