Comparison of Self-Expanding Bioprostheses for Transcatheter Aortic Valve Replacement in Patients with Symptomatic Severe Aortic Stenosis: The SCOPE 2 Randomized Clinical Trial.
There are few randomized trials comparing bioprostheses for transcatheter aortic valve replacement (TAVR), and no trials compared TAVR bioprostheses with supra-annular design. The SCOPE 2 trial was designed to compare the clinical outcomes of the ACURATE neo and CoreValve Evolut valves.
