|Aortic Valve Stenosis||Procedure: Transapical Aortic Valve Implantation Procedure: Conventional Aortic Valve Surgery|
The purpose of the study is to compare the new established apical stent valve treatment with conventional surgical intervention using biological valve prostheses in patients with severe aortic valve stenosis.
The Edwards-SAPIENTM Transcatheter Heart Valve (Edwards Lifesciences, Irvine, CA) will be used in the stent valve group. The Carpentier-Edwards-Perimount Heart Valve (Edwards Lifesciences, Irvine, CA) will be recommended for the conventional surgery group.(Edwards Lifesciences, Irvine, CA).
Heart centres in the Nordic region with experience (>10 cases) in apical stent valve treatment and in conventional surgical treatment of high risk patients with aortic valve stenosis. The study will be initiated at Aarhus University Hospital, Skejby, Denmark.
As compared to conventional aortic valve substitution in patients aged >75 years, apical stent valve treatment reduces the rates of death, cerebrovascular insult (CVI) and need of dialysis for renal failure 1 month after the treatment.
Primary clinical end-point:
Combined end-point consisting of death, CVI and/or renal failure with need for haemodialysis, 1 month after index treatment.
