Long-term clinical outcome and performance of transcatheter aortic valve replacement with a self-expandable bioprosthesis.

European Heart Journal, 2020
AIMS In the last decade, transcatheter aortic valve (TAV) replacement determined a paradigm shift in the treatment of patients with severe symptomatic aortic stenosis. Data on long-term TAV performance are still limited.
