Since the adoption of transcatheter aortic-valve replacement (TAVR), questions have been raised about its effect on clinical practice in comparison with the effect of surgical aortic-valve replacement, which is considered the current standard of care. Complete nationwide data are useful in examining how the introduction of a new technique influences previous clinical standards. ⋯ The use of TAVR increased markedly in Germany between 2007 and 2013; the concomitant reduction in the use of surgical aortic-valve replacement was moderate. Patients undergoing TAVR were older and at higher procedural risk than those undergoing surgical aortic-valve replacement. In-hospital mortality decreased in both groups but to a greater extent among patients undergoing TAVR. (Funded by the Heart Center, Freiburg University.).
