In the evaluation of patients considered for transcatheter aortic valve implantation (TAVI), the EuroScore II might be superior to established risk scores.


We assessed the performance of the EuroScore II in predicting mortality in a cohort of 350 TAVI patients.


The EuroScore II and the logistic EuroScore were higher in nonsurvivors compared to survivors at 30 days (12.6 ± 1.8 vs. 7.5 ± 0.3%, p < 0.001 for EuroScore II, and 27.7 ± 2.8 vs. 22.1 ± 0.8%, p = 0.04 for logistic EuroScore), while the STS-PROM score did not differ (7.3 ± 0.8 vs. 6.4 ± 0.3%, p = 0.09). The area under the curve (AUC) was 0.70 for the EuroScore II, 0.61 for the logistic EuroScore and 0.59 for the STS-PROM score for predicting 30-day mortality. Based on the estimated 30-day mortality risk, 3 risk groups were identified, a low-risk (EuroScore II ≤4%, 30-day mortality 1.2%), an intermediate-risk (EuroScore II between 4% and 9%, 30-day mortality 8.6%) and a high-risk group (EuroScore II >9%, 30-day mortality, 17.1%; p = 0.03). Regarding cumulative mortality, the AUC was 0.67 for the EuroScore II, 0.62 for the logistic EuroScore and 0.55 for the STS-PROM score for predicting mortality at total follow-up.


In this patient cohort, the EuroScore II performed best in predicting short- and long-term mortality.
