Answer

In another randomized study, TAVR using a self-expanding transcatheter aortic-valve bioprosthesis (CoreValve) was associated with a significantly higher survival rate at 1 year follow-up than surgical aortic-valve replacement. [39, 40] The study consisted of 795 patients with severe aortic stenosis who were at increased surgical risk. The rate of death from any cause at 1 year was 14.2% in the TAVR group and 19.1% in the surgical group (P = 0.04). The risk of stroke at 30 days was 4.9% with TAVR and 6.2% with surgery. [39, 40]
