The purpose of the DOUBEL-CHOICE study is to demonstrate non-inferiority of a latest-generation self-expanding valve (SEV) (ACURATE neo2, Boston Scientific, Marlborough, MA, USA) in comparison to another latest-generation SEV (Evolut Pro and Pro+, Medtronic Inc., Minneapolis, MN, USA) and of a minimalist approach vs. standard of care with respect to safety and efficacy in patients with severe symptomatic aortic stenosis undergoing transfemoral TAVI.
Open-label, 2 x 2 factorial, prospective, randomized, national, multicenter study to compare latest-generation self-expanding valves and a minimalist approach versus standard of care in transcatheter aortic valve implantation.
