EuroScore 2 for identification of patients for transapical aortic valve replacement - a single center retrospective in 206 patients

Table 2 Predictive values, specificity and sensitivity of recommended or self-defined cut-offs

	STS	LES	ACEF	Euroscore2
Cut-off	10%	20%	1.28	2.8

NPV	0.96	0.99	1.00	1.00

For the STS score and the LES, predefined cut offs to identify high risk patients were taken from current recommendations. The thresholds for the ACEF and EuroScore2 score were defined from Youden’s Index after recalibration to the current data set. PPV: positive predictive value; NPV: negative predictive value; spec.:specificity; sens: sensitivity; F₁: f-score; AUC: area under the ROC curve.
