In low-volume SAVR centers, 30-day and 1-year mortality are higher with TAVR. So, why does more SAVR make for better TAVR?
Well-established evidence shows a direct correlation between institutional procedural volume of transcatheter aortic valve replacement (TAVR) and patient outcomes. Increasing experience, innovations in valve design and technology, and improvements in patient selection have all combined to produce significant reductions in morbidity and mortality after TAVR.
