Development and validation of a prediction model for early mortality after transcatheter aortic valve implantation (TAVI) based on the Netherlands Heart Registration (NHR): The TAVI‐NHR risk model

Abstract Background The currently available mortality prediction models (MPM) have suboptimal performance when predicting early mortality (30‐days) following transcatheter aortic valve implantation (TAVI) on various external populations. We developed and validated a new TAVI‐MPM based on a large number of predictors with recent data from a national heart registry. Methods We included all TAVI‐patients treated in the Netherlands between 2013 and 2018, from the Netherlands Heart Registration. We used logistic‐regression analysis based on the Akaike Information Criterion for variable selection. W... Mehr ...
