Early and late mortality in patients undergoing transcatheter aortic valve implantation: Comparison of the Novel EuroScore II with established risk scores


Stähli, Barbara E; Tasnady, Hanna; Lüscher, Thomas F; Gebhard, Cathérine; Mikulicic, Fran; Erhart, Ladina; Bühler, Ines; Landmesser, Ulf; Altwegg, Lukas; Wischnewsky, Manfred B; Grünenfelder, Jürg; Falk, Volkmar; Corti, Roberto; Maier, Willibald (2013). Early and late mortality in patients undergoing transcatheter aortic valve implantation: Comparison of the Novel EuroScore II with established risk scores. Cardiology, 126(1):15-23.

Abstract

Objectives: In the evaluation of patients considered for transcatheter aortic valve implantation (TAVI), the EuroScore II might be superior to established risk scores. Methods: We assessed the performance of the EuroScore II in predicting mortality in a cohort of 350 TAVI patients. Results: 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. Conclusions: In this patient cohort, the EuroScore II performed best in predicting short- and long-term mortality.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
