The Association of Transcatheter Aortic Valve Replacement Availability and Hospital Aortic Valve Replacement Volume and Mortality in the United States [1]
This study examined the effect of the introduction of TAVR on overall AVR rates in the US using the STS and STS/ACC registries. From 2008 to 2013, AVR rates increased at hospitals performing TAVR by 69%, including a 22% increase in surgical AVR; the latter increase was primarily in low- and moderate-risk patients. In contrast, non-TAVR hospital AVR volume increased by 16%. Overall survival rates improved during the period in both settings.
