Fig 1 Receiver-operating characteristic curve of the systolic mitral annular velocity (Sm) for postoperative left ventricular reverse remodeling. An area of 0.721 and a p value less than 0.001 were observed below the line of the Sm with a 95% confidence interval of 0.64 to 0.80. The optimal cutoff value for postoperative left ventricular reverse remodeling was 7.0 cm/s of Sm, with a sensitivity and specificity of 63.0% and specificity 71.0%, respectively. Left ventricular reverse remodeling was defined as the changes of left ventricular mass index 20% or greater from baseline value. Diagonal segments are produced by ties.
