Primary Outcome Measures:
  • All-cause mortality rate [ Time Frame: 30 days post implant ]
    All-cause mortality rate at 30 days post procedure


Secondary Outcome Measures:
  • Device success according to VARC2 [ Time Frame: 24h to 7 days post implant ]

    Device success rate at 24 hours to 7 days, defined according to the Valve Academic Research Consortium-2 (VARC-2) guidelines as:

    • Absence of procedural mortality, AND
    • Correct positioning of a single prosthetic heart valve into the proper anatomical location, AND
    • Intended performance of the prosthetic heart valve, defined as the absence of patient-prosthesis mismatch and mean gradient < 20 mmHg (or peak velocity < 3 m/sec), AND No moderate or severe prosthetic valve regurgitation.

  • Hemodynamic performance [ Time Frame: 24h to 7 days and 1 year post implant ]
    Hemodynamic performance at 24 hours to 7 days (discharge) and 1 year post procedure, including the mean prosthetic valve gradient as measured by transthoracic echocardiography (TTE) and assessed by an independent core laboratory.

  • Hemodynamic performance [ Time Frame: 24h to 7 days and 1 year post implant ]
    Hemodynamic performance at 24 hours to 7 days (discharge) and 1 year post procedure, including the effective orifice area as measured by transthoracic echocardiography (TTE) and assessed by an independent core laboratory.

  • Hemodynamic performance [ Time Frame: 24h to 7 days and 1 year post implant ]
    Hemodynamic performance at 24 hours to 7 days (discharge) and 1 year post procedure, including the degree of prosthetic valve regurgitation (transvalvular, paravalvular, and total) as measured by transthoracic echocardiography (TTE) and assessed by an independent core laboratory.

  • Early safety composite endpoint according to VARC2 [ Time Frame: 30 days post implant ]

    Early Safety composite endpoint at 30 days post procedure, defined according to the VARC-2 guidelines, defined as any of the following components:

    • All-cause mortality
    • All stroke (disabling and non-disabling)
    • Life-threatening bleeding
    • Acute kidney injury: stage 2 or 3 (including renal replacement therapy)
    • Coronary artery obstruction requiring intervention
    • Major vascular complication
    • Valve-related dysfunction requiring repeat procedure (BAV, TAVI, or SAVR)

  • Event rates according to VARC2 [ Time Frame: 30 days post implant ]
    Event rates of the individual components of the VARC-2 composite Early Safety endpoint at 30 days post procedure

  • Rate of new permanent pacemaker implant [ Time Frame: 30 days post implant ]
    Rate of new permanent pacemaker implant at 30 days post procedure

Intervention Details:
    Device: Medtronic CoreValve™ Evolut R™ System
    The Evolut R System is intended for relief of aortic stenosis in patients with symptomatic heart disease due to severe native calcific aortic stenosis who are judged by a heart team, to be at high or extreme risk for open heart surgery. The Evolut R TAV treats aortic stenosis by displacing and functionally replacing the dysfunctional native valve with a bioprosthetic valve delivered on a catheter while the heart is still beating, thus avoiding the risks of cardiopulmonary bypass. Its intended performance is to relieve aortic valve stenosis without inducing significant regurgitation, thereby restoring effective aortic valve function.
Detailed Description:

The study objective is to document the clinical and device performance outcomes of the Evolut R system used in routine hospital practice in a large patient cohort for the treatment of symptomatic native aortic valve stenosis or a stenosed, insufficient, or combined surgical bioprosthetic valve failure necessitating valve replacement.

Prospective, single arm, multi-center, observational, post market study. In Australia and Canada it is a prospective, single arm, multi-center pre-market study.

Up to 60 centers worldwide. Geographies may include Europe, Australia, Middle East and Africa, Latin America and Canada.

Approximately 1000 implanted subjects, consented for follow-up through three years.

For each subject, data will be collected preoperatively, intra-operatively, at hospital discharge, 30 days, 1, 2 and 3 years.

  Eligibility

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
The study population includes patients with symptomatic native aortic valve stenosis or a stenosed, insufficient, or combined surgical bioprosthetic valve failure necessitating valve replacement who are scheduled for an elective transcatheter aortic valve implantation. Patients who will undergo an emergency procedure should not be included in this study.
