Abstract

Abstract Objective To assess temporal trends of patient baseline characteristics, risk profile and outcome of transcatheter aortic valve implantation (TAVI) between 2013 and 2020. Background Guideline recommendations and increasing confidence in TAVI therapy may have changed the selection of TAVI patients. Methods 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. Results 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 < 0.001) as a consequence of lower comorbidity burden, whereas mean age remained unchanged (2013 81.0 ± 6.1; 2020 80.8 ± 6.4; P = 0.976) with patients ≥ 80 years accounting for about two-third of the treated cohort. Periprocedural complications including bleeding (2013 24.5%; 2020 12.1%; P < 0.001), vascular complications (2013 20.7%; 2020 11.7%; P < 0.001) and new permanent pacemaker implantation (2013 20.1%; 2020 13.8%, P < 0.001) decreased significantly. Similarly, the 30-day mortality decreased from 5.4% to 2.1% (P < 0.001), but remained high in high-risk patients (STS > 8% 2013 7.5%; 2020 6.9%; P = 0.778). Conclusion 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. Graphical abstract
