Pepe M, Corcione N, Petronio AS, et al. - For patients undergoing transcatheter aortic valve implantation (TAVI), the ACC/TVT score is a specific predictive model of in-hospital mortality. This study was undertaken to investigate its predictive accuracy compared with standard surgical risk models (Logistic Euroscore, Euroscore II, and STS-PROM) in the population of TAVI patients included in the multicenter RISPEVA (Registro Italiano GISE sull'impianto di Valvola Aortica Percutanea) registry. Furthermore, 3,293 patients who had undergone TAVI between 2008 and 2019 were included in this study cohort. They estimated 4 risk scores for all patients. The data displayed that the ACC/TVT score demonstrated better prediction accuracy for estimation of 30-day mortality in terms of calibration compared with the standard surgical risk models. However, its predictive reliability remained suboptimal and tended to worsen in individuals treated more recently.
