With initiation of transcatheter aortic valve replacement (TAVR) programs, centers may see changes in surgical aortic valve replacement (SAVR) populations and related outcomes because of more high-risk patients undergoing TAVR rather than SAVR. Little data exist on the potential changes in the risk profiles and outcomes of SAVR patients from the pre- to post-TAVR eras. As such, this study sought to evaluate changes in the SAVR population at a tertiary referral center after TAVR program initiation. ⋯ Consistent with previous studies, initiation of a TAVR program was associated with increased SAVR volume. Risk profiles for SAVR patients in the TAVR era remained similar by the STS-PROM, indicating generally stable risk among surgical patients after launching a TAVR program. These data suggest that significant changes in the risk profiles of SAVR patients should not be expected with the initiation of a TAVR program. Further research will need to reevaluate these changes once TAVR becomes more widely available.

Contemporary Costs Associated With Transcatheter Aortic Valve Replacement: A Propensity-Matched Cost Analysis.
The Placement of Aortic Transcatheter Valve (PARTNER) trial suggested an economic advantage for transcatheter aortic valve replacement (TAVR) for high-risk patients. The purpose of this study was to evaluate the cost effectiveness of TAVR in the "real world" by comparing TAVR with surgical aortic valve replacement (SAVR) in intermediate-risk and high-risk patients. ⋯ TAVR was associated with greater total costs and mortality compared with SAVR in intermediate-risk and high-risk patients while conferring lower major morbidity and improved resource use. Increased cost of TAVR appears largely related to the cost of the valve. Until the price of TAVR valves decreases, these data suggest that TAVR may not provide the most cost-effective strategy, particularly for intermediate-risk patients.
