Durability of newer TAVR valve comparable to that with SAVR

Reuters Health - 13/10/2020 - Following transcatheter aortic valve replacement (TAVR) using a 3rd generation device, structural valve deterioration (SVD) does not differ markedly from that following surgical aortic valve replacement (SAVR), according to an analysis of trial and registry data. As Dr. Philippe Pibarot explained in an email to Reuters Health, "The mid-term, i.e. 5-year, durability of TAVR with the second generation of balloon-expandable valve: SAPIEN XT is inferior that of SAVR. However, the good news is that durability of TAVR with the 3rd generation, the SAPIEN 3, is similar to SAVR." Dr. Pibarot of Laval University, Quebec, Canada, and colleagues studied data from the randomized PARTNER 2A trial, in which patients received either TAVR with the SAPIEN XT or SAVR. Also included were registry entries covering patients assigned to TAVR with the SAPIEN 3. SVD-assessments and echocardiographic data on valve function were available for 774 patients ...
