Fig 2 Kaplan-Meier survival curves for patients according to preoperative MR status. There was no difference in 10-year survival among groups according to preoperative MR status (grade I, 93.1%; grade II, 85.4%; grade III, 80%; p = 0.432). (MR = mitral regurgitation.)

Fig 3 Kaplan-Meier survival curves for patients with persistent postoperative MR compared with those without persistent MR. There was a significant difference in survival between the two groups (93.1% versus 77.8%, p = 0.036) at 10 years. (MR = mitral regurgitation.)
