Background

Patterns of diffusion of TAVR in the United States (U.S.) and its relation to racial disparities in TAVR utilization remain unknown.

We identified TAVR hospitals in the continental U.S. from 2012-2017 using Medicare database and mapped them to Hospital Referral Regions (HRR).

Using a discrete time hazard logistic regression model, we examined the association of hospital and HRR variables with the opening of a TAVR program.

Results

The number of TAVR hospitals increased from 230 in 2012 to 540 in 2017. The proportion
