ABSTRACT
Background Transcatheter aortic valve replacement (TAVR) has transformed the management of aortic valve stenosis. However, little national data are available characterizing the geographic and demographic dispersion of this disruptive technology relative to surgical aortic valve replacement (SAVR). Methods and Results In this US claims-based study, we analyzed a 100% sample of fee-for-service Medicare beneficiaries from 2012 to 2017 and examined national rates of TAVR versus SAVR. Procedure rates were compared across years as a function of age, sex, race, and geography for TAVR and SAVR beneficiaries. There was significant growth in TAVR from 15.4 beneficiaries/100 000 enrollees in 2012 to 90.6 in 2017 (P<0.001). SAVR rates declined from 92.8 beneficiaries/100 000 enrollees in 2012 to 63.5 in 2017 (P<0.001). The growth of TAVR varied as a function of age (P<0.0001). While TAVR was the dominant strategy among beneficiaries ≥85 and 75 to 84 years old, SAVR was more common among beneficiaries 65 to 74 years old. TAVR was also used more frequently than SAVR among women (P<0.001). While TAVR increased among all races, it was less commonly used among non-White beneficiaries (P<0.001). Contemporary use of TAVR relative to SAVR varied significantly by geographic location, with a TAVRSAVR ratio in 2017 of 1.24 in the Midwest and 1.68 in the Northeast (P<0.001). Conclusions In 2017, the number of Medicare beneficiaries receiving TAVR exceeded SAVR for the first time in the United States. There is significant variation, however, in the geographic expansion of TAVR and in patient demographics relative to SAVR.
