Mentias A, Sarrazin MV, Desai M, et al. - Researchers conducted the study for analyzing the patterns of diffusion of transcatheter aortic valve replacement (TAVR) in the US and its relation to racial disparities in TAVR utilization. From 2012-2017, TAVR hospitals in the continental US were identified using the Medicare database and mapped to Hospital Referral Regions (HRR). From 230 in 2012 to 540 in 2017, the number of TAVR hospitals has risen. A rise in geographic coverage for all racial subgroups has followed the expansion of TAVR programs in the U.S. In order to identify reasons for TAVR underutilization in Blacks and Hispanics, further study is required.
