Abstract

BACKGROUND: Recent studies have shown that transcatheter aortic valve implantation (TAVI) is non-inferior to surgical aortic valve replacement (SAVR) for treatment of low-risk patients with severe aortic stenosis (AS). However, the cost-effectiveness of TAVI in this population is unknown. We sought to evaluate the cost-effectiveness of both balloon-expandable and self-expanding TAVI compared to SAVR in patients with severe AS at low operative risk. METHODS: We developed a Markov model comparing TAVI to SAVR over a lifetime horizon. Key data inputs were drawn from the Placement of AoRTic TraNscathetER Valve (PARTNER) 3 trial for balloon-expandable TAVI and the Evolut Low-Risk trial for self-e..
