Brief Summary
The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis. Additionally, a stress echocardiography sub-study will be conducted as part of the SMART Trial at select sites. The purpose of the sub-study is to evaluate performance of SE versus BE TAVR in subjects with a small aortic annulus and symptomatic severe native aortic stenosis after undergoing exercise stress echocardiographic testing.

Primary Outcomes (2)
Mortality, Disabling Stroke or Heart Failure Rehospitalization
Percentage of participants with all-cause mortality, disabling stroke, or heart failure rehospitalization.
12 months
Bioprosthetic Valve Dysfunction (BVD)
Percentage of participants with BVD as determined by echocardiography (hemodynamic structural valve dysfunction (aortic valve no longer works properly as measured by hemodynamic mean gradient ≥ 20mmHg), non-structural valve dysfunction (severe prosthesis-patient mismatch (valve is too small) and/or ≥ moderate total aortic regurgitation (backward flow of blood)), thrombosis (formation of a blood clot), endocarditis (inflammation of the endocardium - the inner lining of the heart chambers and valves), or aortic valve re-intervention (a follow-up procedure to fix or replace the aortic prosthetic valve))

Study Arms (2)
Medtronic Self-Expanding TAV
EXPERIMENTALSubjects will be randomized on a 1:1 basis to receive TAVR with either a Medtronic SE TAV or an Edwards BE THV.
Edwards Balloon-Expandable THV
EXPERIMENTALSubjects will be randomized on a 1:1 basis to receive TAVR with either a Medtronic SE TAV or an Edwards BE THV.
Interventions
TAVR treatment with Medtronic Evolut PRO, PRO+ System or Evolut FX System (where commercially available)
TAVR treatment with Edwards SAPIEN 3 or SAPIEN 3 Ultra System
Eligibility Criteria
You may qualify if:
- Heart Team agrees that the subject is deemed symptomatic and is a candidate for transcatheter aortic valve replacement (TAVR)
- Subject has a predicted risk of operative mortality \< 15% as determined by the local Heart Team
- Subject has severe aortic stenosis as determined by transthoracic echocardiography (TTE) at rest
- Subject has a small aortic annulus as determined by Multi-detector computed tomography (MDCT)
- Subject's anatomy is appropriate for both Medtronic Evolut PRO/PRO+/FX TAV and Edwards SAPIEN 3/3 Ultra TAV
- Subject's anatomy is suitable for TAVR via transfemoral vessel access
- Subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits
You may not qualify if:
- Estimated life expectancy of fewer than 2 years
- Multivessel coronary artery disease with a Syntax score \>32 and/or unprotected left main coronary artery(Syntax score calculation is not required for patients with history of previous revascularization if repeat revascularization is not planned).
- Participating in another trial that may influence the outcome of this trial
- Need for an emergent procedure for any reason
- Contraindicated for treatment with the Evolut PRO/PRO+/FX and Edwards SAPIEN 3/3 Ultra TAV in accordance with the Instructions for Use
- Other medical, social, or psychological conditions that in the opinion of the Investigator precludes the subject from appropriate consent or adherence to the protocol required follow-up exams
- Pregnant, nursing, or planning to be pregnant
- Subject is less than the legal age of consent, legally incompetent, unable to provide his/her own informed consent, or otherwise vulnerable
- Subject has an active COVID-19 infection or relevant history of COVID-19
- Previous aortic valve replacement
