Clinical Trial Summary

Clinical trial aimed at evaluating the safety and performance of the ACURATE neo™ AS Aortic Bioprosthesis and ACURATE neo™ AS TF Transfemoral Delivery System for CE mark approval purposes.

Description:

Single arm, prospecitve, multicenter, non-randomized and open trial. The purpose of this trial is to collect and safety and performance data concerning the ACURATE neo™ AS Aortic Bioprosthesis and ACURATE neo™ AS TF Transfemoral Delivery System

The ACURATE neo™ AS Aortic Bioprosthesis and ACURATE neo™ AS TF Transfemoral Delivery System are intended for use in minimally invasive, transcatheter aortic valve replacement (TAVR) using transfemoral access in patients presenting with severe aortic valve stenosis.

The primary objective is to evaluate the safety and performance of the study device in patients presenting with severe aortic stenosis (AS) considered to be high risk for surgery.

The secondary objective is to evaluate adverse events and study device performance.

20. Refusal of blood transfusions

21. Systolic pressure <80mmHg, cardiogenic shock, need for inotropic support or IABP

22. Hypertrophic cardiomyopathy with or without obstruction

31. Contraindication to contrast media or allergy to nickel

32. Currently participating in an investigational drug or another device study

33. Non-valvular aortic stenosis

34. Non-calcific acquired aortic stenosis
