Over the same period, the number of TAVI procedures increased from 15\u2009653 to 21\u2009501, an increase of 37.3%. Regarding in-hospital mortality following TAVI, there was a decline from 4% (2015) to 2.5% (2020), while in-hospital mortality following SAVR remained nearly constant at 3%. Over the study period, there is an overestimation of TAVI risk while simultaneously underestimating SAVR risk by EuroSCORE II. In contrast, the mortality risk of patients is well estimated using the AKL-Kath Score in the TAVI group and the AKL-Chir Score in the SAVR group. The AKL-Chir Score in TAVI patients overestimates their mortality, while the AKL-Kath Score underestimates the mortality of SAVR patients.<\/jats:p>\n                  <\/jats:sec>\n
