Brief Summary: To establish the safety and effectiveness of surgical aortic valve replacement (SAVR) in patients with isolated severe, calcific aortic stenosis who are at low surgical risk.
Detailed Description: This study is the Prospective, Randomized, Controlled, Multi-center Study of Isolated SAVR in Low Risk AS Patients (The AMETHYST trial). Patients will be randomized 1:1 to receive either SAVR or transcatheter heart valve replacement (TAVR) with a commercially available surgical and transcatheter bioprosthetic valves. The aim of this study was to assess the non-inferiority of SAVR compared with TAVR for the combined endpoints of death from any cause, stroke and rehospitalization (hospitalization related to biological valves or procedures or heart failure) at 1 year postoperatively. Patients will be seen for follow-up visits at discharge, 30 days, and annually through 10 years.
