Transcatheter aortic valve replacement (TAVR) has become a well-established treatment for patients with severe aortic stenosis. At present, TAVR has already shown noninferiority and even superiority to surgical aortic valve replacement (SAVR) in patients deemed at high or intermediate risk for SAVR. However, the long-term follow-up results of the randomized controlled trials comparing the efficacy and safety between TAVR and SAVR are still lacking in those patients who are at low risk for SAVR. This paper gives an overview and reviews results of the Evolut Low Risk trial and interprets its implications for transcatheter therapy in aortic valve diseases.
