ALLIANCE: Safety and Effectiveness of the SAPIEN X4 Transcatheter Heart Valve

Brief Summary
The objective of this study is to establish the safety and effectiveness of the Edwards SAPIEN X4 Transcatheter Heart Valve (THV) in subjects with symptomatic, severe, calcific aortic stenosis (AS).
Brief Title
ALLIANCE: Safety and Effectiveness of the SAPIEN X4 Transcatheter Heart Valve
Detailed Description
This is a prospective, single arm, multicenter study. Subjects with bicuspid aortic valve morphology will be enrolled in a separate registry.

Conditions
Aortic Stenosis, Severe
Eligibility Criteria
Inclusion Criteria:

1. Severe, calcific AS
2. Native aortic annulus size suitable for SAPIEN X4 THV
3. NYHA functional class ≥ II
4. The subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent.

Exclusion Criteria:

1. Anatomical characteristics that would preclude safe femoral placement of the introducer sheath or safe passage of the delivery system
2. Aortic valve is unicuspid, bicuspid or non-calcified
3. Pre-existing mechanical or bioprosthetic valve in any position
4. Severe aortic regurgitation (\> 3+)
5. Severe mitral regurgitation (\> 3+) or ≥ moderate mitral stenosis
6. Need for mitral, tricuspid or pulmonic valve intervention within the next 12 months
7. Left ventricular ejection fraction \< 20%
8. Cardiac imaging evidence of intracardiac mass, thrombus or vegetation
9. Left ventricular outflow tract calcification that would increase the risk of annular rupture or significant PVL after THV implantation
10. Increased risk of coronary artery obstruction after THV implantation
11. Myocardial infarction within 30 days prior to the study procedure
12. Hypertrophic cardiomyopathy with subvalvular obstruction
13. Subjects with planned concomitant ablation for atrial fibrillation
14. Complex coronary artery disease (CAD) that cannot be optimally treated by percutaneous coronary intervention (PCI)
15. Any surgical or transcatheter procedure within 30 days prior to the study procedure (unless part of planned strategy for treatment of CAD). Implantation of a permanent pacemaker or implantable cardioverter defibrillator (ICD) is not considered an exclusion.
16. Any planned surgical or transcatheter intervention to be performed within 30 days following the study procedure (unless part of planned strategy for treatment of CAD)
17. Endocarditis within 180 days prior to the study procedure
18. Stroke, transient ischemic attack or neurological signs and symptoms attributed to carotid or vertebrobasilar disease within 90 days prior to the study procedure
19. Hemodynamic or respiratory instability requiring inotropic or mechanical support within 30 days prior to the study procedure
20. Renal insufficiency and/or renal replacement therapy
21. Leukopenia, anemia, thrombocytopenia
22. Inability to tolerate or condition precluding treatment with antithrombotic therapy
23. Hypercoagulable state or other condition that increases risk of thrombosis
24. Absolute contraindications or allergy to iodinated contrast that cannot be adequately treated with premedication
25. Subject refuses blood products
26. BMI \> 50 kg/m2
27. Estimated life expectancy \< 24 months
28. Female who is pregnant or lactating
29. Active SARS-CoV-2 infection or previously diagnosed with COVID-19 with sequelae that could confound endpoint assessments
30. Participating in another investigational drug or device study that has not reached its primary endpoint
31. Subject considered to be part of a vulnerable population

Primary Outcomes
Outcome Description
The number of patients that died or had a stroke
Outcome Measure
Non-hierarchical composite of death and stroke
Outcome Time Frame
1 year
Secondary Outcomes
Outcome Description
The number of patients that met all of these criteria. The KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
Outcome Time Frame
1 year
Outcome Measure
Favorable outcome per VARC-3: Composite of 1) alive, 2) Kansas City Cardiomyopathy Questionnaire (KCCQ) score ≥ 60, and 3) KCCQ score decrease ≤10 points from baseline
Outcome Description
Paravalvular leak will be categorized as None, Trace, Mild, Mild-Moderate, Moderate, Moderate-Severe, or Severe
Outcome Time Frame
30 days
Outcome Measure
Paravalvular leak
