Receiver operating characteristic curve showing LV end-diastolic dimension as a predictor of recurrent moderate or severe mitral regurgitation in patient with atrial functional mitral regurgitation. The LVDd of 61 mm had a sensitivity of 91% and a specificity of 80% for predicting recurrent moderate or severe mitral regurgitation. The area under the curve for LV end-diastolic dimension was 0.897. LV = left ventricular
