Outcome Measures

Primary Outcomes (2)

  • Freedom from all-cause mortality at 30 day Follow Up

    The primary study objective is to evaluate the safety of the ACURATE™ Transapical Aortic Bioprosthesis at 30 days post-procedure in patients presenting with severe aortic valve stenosis at high risk for conventional AVR surgery.

    30-Day Follow-up

  • Freedom from all-cause mortality at 12 months Follow Up

    The primary study objective is to evaluate the safety of the ACURATE™ Transapical Aortic Bioprosthesis at 12 months post-procedure in patients presenting with severe aortic valve stenosis at high risk for conventional AVR surgery.

    12 months Follow-Up

Secondary Outcomes (5)

  • Rate of Major Adverse Valve-Related Events (MAVRE) at 30 days and at 12 month follow up related to the study device as defined as;

    30-Days and at 12 Months Follow-up

  • Rate of Major Adverse Cardiac and Cerebrovascular-Related Events (MACCE) at 30 days and at 12 Month and defined as cardiovascular death, myocardial infarction and stroke.

    30-Day and 12-Month

  • Functional Improvement from baseline

    30-Days and 12-Month Follow-up

  • Procedural success

    24 hours Post-Procedure

  • Device success at 30 Days and 12 Month follow-up as defined as adequate functioning of the study device as confirmed by angiography and/or echocardiography as assessed at a CoreLab.

    30-Day and 12-Month Follow-up

Study Arms (1)

ACURATE TA™

EXPERIMENTAL

Patient implanted with ACURATE TA™ Bioprosthesis

Device: ACURATE TA™

Interventions

ACURATE TA™ Transapical Aortic Bioprosthesis is intended for subjects with severe symptomatic Aortic Stenosis and are considered high risk for surgical conventional Aortic Valve Replacement Surgery.

Also known as: ACURATE TA™ Transapical Aortic Bioprosthesis and Delivery System
ACURATE TA™

Eligibility Criteria

  • NYHA Functional Class \> II
  • Aortic annulus (AAn) diameters between and including 21 mm up to 27 mm (21mm ≤ AAn ≤27mm) by transoesophageal echocardiography (TEE)
  • Patient understands the implications of participating in the study and provides signed informed consent

You may not qualify if:

  • Congenital unicuspid or bicuspid aortic valve
  • Severe eccentricity of calcification
  • Severe mitral regurgitation (\> 2°)
  • Pre-existing prosthetic heart valve in any position and / or prosthetic ring
  • Severe transapical access problem, non-reachable LV apex
  • Previous surgery of the LV using a patch, such as the Dor procedure
  • Presence of apical LV thrombus
  • Echocardiographic evidence of intracardiac mass, thrombus, or vegetation
  • Acute myocardial infarction (AMI) within 1 month prior to the procedure
  • PCI within 1 month prior to the procedure
  • Previous transient ischemic attack (TIA) or stroke in the last 3 months
  • Untreated clinically significant coronary artery disease (CAD) requiring revascularization
  • Hemodynamic instability: systolic pressure \<90mmHg without afterload reduction, shock, need for inotropic support or intra-aortic balloon pump
  • Severe left ventricular dysfunction (LVEF) \< 30% by echocardiography
  • Calcified pericardium
  • +15 more criteria
