Aortic Stenosis | Procedure: SAVR Device: SAPIEN 3 THV | Not Applicable |
Prospective, randomized, controlled, multi-center trial. Patients having an operative mortality < 4% (low operative risk) for surgical aortic valve replacement will be randomized 1:1 to receive either transcatheter heart valve replacement (TAVR) with the Edwards SAPIEN 3 or aortic valve replacement with a commercially available surgical bioprosthetic valve. Patients will be seen for follow-up visits at discharge, 30 days, 6 months, and annually through 10 years.
A subset of PARTNER 3 randomized patients will be enrolled in the Actigraphy/Quality of Life. Additional patients will be enrolled in either the Bicuspid Registry, Underrepresented Populations Registry (UPR) or the Alternative Access Registry.

- Severe mitral regurgitation (>3+) ≥ moderate stenosis
- Pre-existing mechanical or bioprosthetic valve in any position
-
Complex coronary artery disease:
- Unprotected left main coronary artery
- Syntax score > 32
- Heart Team assessment that optimal revascularization cannot be performed
- Symptomatic carotid or vertebral artery disease or successful treatment of carotid stenosis within 30 days of randomization

- Inability to tolerate or condition precluding treatment with antithrombotic/anticoagulation therapy during or after the valve implant procedure
- Stroke or transient ischemic attack within 90 days of randomization
- Renal insufficiency and/or renal replacement therapy at the time of screening.
- Active bacterial endocarditis within 180 days of randomization
- Severe lung disease or currently on home oxygen
- Severe pulmonary hypertension
