The effect of hospital market competition on the adoption of transcatheter aortic valve replacement.
The use of transcatheter aortic valve replacement (TAVR) has grown rapidly. The purpose of this study was to assess whether hospital market competition was associated with the use of TAVR. The investigators concluded that market competition was positively associated with a hospital's adoption of TAVR and indicated that future studies should further examine the impact of competition on quality and appropriateness.

Trends in isolated surgical aortic valve replacement according to hospital-based transcatheter aortic valve replacement volumes.
This research analyzed trends in isolated surgical aortic valve replacement (SAVR) procedures with the advent of the transcatheter aortic valve replacement (TAVR) procedure. Hospitalizations of adults from January 2011 through December 2014 was analyzed with data from the Medicare Provider Analysis and Review database using ICD-9 Revision-Clinical Modification procedure codes. The annual value of isolated SAVR went down as TAVR volumes increased which also decreased short- and long-term mortality over the study period.
