TAVI risk scoring using established versus new scoring systems: role of the new STS/ACC model.

Aims: The aim of this study was to validate the recently developed STS/ACC TAVR in-hospital mortality risk score for predicting in-hospital mortality after transcatheter aotic valve implantation (TAVI) and to compare its ability to predict 30-day mortality with that of four other established risk models (EuroSCORE I, EuroSCORE II, STS-PROM, and German AV Score).

Methods And Results: The study cohort included 946 consecutive patients who underwent TAVI between 2013 and 2015. Each of the five scores was fitted as a continuous linear variable into a logistic regression model estimating 30-day mortality.
