Aortic Stenosis
Conditions
Brief summary
To compare outcome in patients randomized to treatment with Evolut FX versus Sapien 3 Ultra Resilia.
Detailed description
The purpose of the "Compare-TAVI" organization is to ensure a continuous comparison of the TAVI-valves implanted, and to monitor long-term valve performances. Purpose of present study: To compare outcome in patients randomized to treatment with Evolut FX versus Sapien 3 Ultra Resilia. Hypotheses: 1. Evolut FX is non-inferior to Edwards Sapien 3 Resilia with regard to the combined endpoint (death, stroke, moderate/severe aortic regurgitation, moderate/severe valve deterioration) between the two valves being compared. 2. There is no difference between valves in secondary safety and efficacy endpoints (see below) 3. There is no difference in Aortic Regurgitation fraction (ARF) and Effective Orifice Area (EOA) measured by CMR (CMR-substudy, N=166) 4. There is no difference in EOA measured invasively during dobutamine stress (hemodynamic substudy, N=440). 5. There is no difference in occurrence of Hypoathenuated Leaflet Thickening (HALT) measured by CT (CT-substudy, N=778).

Masking description
The patient and operator cannot be blinded to allocated treatment. Most outcomes are registry based and randomization is not anticipated to impact outcome assessment.
Intervention model description
Randomized 1:1
Eligibility
Inclusion criteria
1. Patient more than 18 years of age. 2. Patient eligible for both Evolut FX and Edwards Sapien 3 Ultra Resilia according to a TAVI heart team conference. 3. The center experience for each of the valves considered should be more than 15 cases a year, and the treating physician should have implanted at least 15 of each valve used in the trial. 4. The center volume should be more than 75 cases a year. 5. The patient has given signed informed consent. 6. TAVI performed via the femoral artery.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mortality, stroke, moderate/major aortic regurgitation, moderate/severe THV deterioration | 1-year, 3-year, 5-year, 10-year | The primary composite endpoint is at one-year, and a non-inferiority test is performed. See separate statistical analysis plan. Separate analyses of each component of the primary outcome will be presented, in accordance with the FDA guidelines and EMA guidelines, i.e. mortality, stroke, moderate/severe aortic regurgitation and moderate/severe THV deterioration to better understand their contribution to the primary endpoint. If non-inferiority is proven for the primary composite endpoint, a split alfa is used to test for superiority if possible (alfa=0.025) and to test secondary safety and efficacy endpoints (Total alfa=0.025 for these). The composite endpoint will be re-analyzed after 3-, 5- and 10-year as superiority analyses. |

| Proportion with successful implantation of the chosen valve. | 7-days | This means no need for more than 1 TAVI valve, no change to another valve than planned during the procedure because it was impossible to implant the valve planned, and no conversion to surgery or procedure-related death. |
| SMART criteria for bioprosthetic valve dysfunction through 12 months | 1-year | composed of the following components: (1) hemodynamic structural valve dysfunction, defined as aortic valve mean gradient ≥ 20 mmHg at any time up to the 12-month visit echo; (2) nonstructural valve dysfunction, defined as severe prosthesis-patient mismatch or ≥ moderate total aortic regurgitation at any time up to the 12-month visit echo; (3) clinical valve thrombosis; (4) endocarditis; or (5) aortic valve reintervention. |
| Pacemaker-implantation | 1-year | New pace-maker implantation in pacemaker-naive patients. |
| Vascular and access-related complications (exploratory only) | 30-days | Major vascular access site and access-related complications resulting in endovascular or open surgery using VARC-3 criteria |
| Bleeding and transfusion (exploratory only) | 30-days | Major bleeding resulting in drop in hgb-level ≥1.86 mmol/l and/or erythrocyte transfusion ≥ 2 units, modified from BARC type 3-5 criteria |
