Kaplan-Meier analysis: Freedom from recurrent mitral regurgitation (MR) and survival. A, Freedom from recurrent MR in unmatched cohorts. There were 270 subjects in the partial ring group (black line); and 209 subjects in the complete ring group (gray dash). B, Survival curves in unmatched cohorts. There were 270 in the partial ring group (black line); and 209 subjects in the complete ring group (gray dash). C, Freedom from recurrent MR in risk-matched cohorts (n = 102 patients per group).
