Fig. 1From: Predictors of improvement in left ventricular systolic function after catheter ablation in patients with persistent atrial fibrillation complicated with heart failureA receiver operating characteristic analysis revealed a moderate accuracy of predicting the improvement of LVEF by left ventricular end-diastolic diameter (LVDd) with a cutoff of 59Â mm (sensitivity: 85.0%, specificity: 55.0%, area under curve: 0.709)Back to article page
