Temporal trends of TAVI treatment characteristics in high volume centers in Germany 2013–2020

To assess temporal trends of patient baseline characteristics, risk profile and outcome of transcatheter aortic valve implantation (TAVI) between 2013 and 2020. Guideline recommendations and increasing confidence in TAVI therapy may have changed the selection of TAVI patients. Baseline risk profile and VARC-2 outcome of 15,344 patients undergoing TAVI at 5 high volume centers in Germany over the time period 2013–2020 was analyzed. Over the 8 years, annual TAVI volumes more than doubled from 1071 in 2013 to 2996 in 2020. The baseline surgical risk estimated by the Society of Thoracic Surgeons (STS) score declined from 7.2 ± 6.2% to 4.6 ± 3.7% (P   8% 2013 7.5%; 2020 6.9%; P = 0.778). From 2013 to 2020, mortality and burden of complications following TAVI procedure significantly decreased in a large multicenter registry from Germany. Proportion of elderly patients remained stable, while the surgical risk profile decreased.
