- Abstract: 24 mm² (sensitivity, 76.5%; specificity 64.8%), and the area under the ROC curve (AUC) was 0.72. For ASR(area), the cut-off value was > 1.58 (sensitivity, 76.5%; specificity, 58.0%) and the AUC was 0.64. Multivariable Cox regression showed that ARO > 24 mm² (hazard ratio = 3.79, p = 0.020) was a potential independent parameter for recurrent 3 + AR. ROC for the linear regression model showed that the AUC for both ARO and ASR(area) was 0.73 (95% confidence interval, 0.64–0.81, p < 0.001).CONCLUSION: ARO and ASR(area) detected on preoperative cardiac CT would be potentially helpful for identifying AR patients who may benefit from the David operation.]]>
