1. Transcatheter versus Surgical Aortic Valve Replacement Objective:to assess the clinical outcomes of transcatheter versus surgical aortic valve replacement Study:multicenter randomized controlled study (non-inferior) Population:patients at high-risk if surgical procedural complications, with severe aortic valve stenosis (<0.8cm 2 ) considered candidates for surgery Endpoint:all-cause death at 1 year Objective:to assess the clinical outcomes of transcatheter versus surgical aortic valve replacement Study:multicenter randomized controlled study (non-inferior) Population:patients at high-risk if surgical procedural complications, with severe aortic valve stenosis (<0.8cm 2 ) considered candidates for surgery Endpoint:all-cause death at 1 year
