Vemulapalli S, et al. - Using data from the Transcatheter Valve Therapy Registry from 2015 through 2017, researchers evaluated the correlation between hospital procedural volume as a continuous variable and risk-adjusted mortality at 30 days following transfemoral transcatheter aortic-valve replacement (TAVR). There were 113,662 TAVR procedures conducted by 2,960 operators in 555 hospitals; 96,256 involved a transfemoral approach. For transfemoral TAVR procedures from 2015 through 2017, an inverse volume-mortality association was noted. In hospitals with low procedural volume, mortality at 30 days was higher and more variable vs hospitals with high procedural volume.
