Multicenter Study Evaluating the Efficacy of an Intervention Aimed At Reducing the Length of Stay After Transfemoral Transcatheter Aortic Valve Implantation

Since the first implantation of a percutaneous aortic bioprosthesis (TAVI) in 2002 (Cribier et al. Circulation 2002), TAVI occupies an increasing place in the management of aortic stenosis (AR) . Initially reserved for inoperable patients at high surgical risk, TAVI is also recommended in patients at intermediate risk, especially when a femoral approach (TF) is possible (Baumgartner et al. Eur Heart J. 2017). Currently, there is no recommendation regarding length of stay after TAVI and practices are extremely heterogeneous. Despite the growing experience of centers, better patient selection and a reduction in complications, the length of stay after TAVI remains very high in France. Faced with the great disparity observed between the centers, efforts are necessary to educate the centers in order to further reduce the length of stay after TF-TAVI. The aim of the study is to evaluate the effectiveness of an intervention based on training teams to reduce the length of stay after TF-TAVI.
