EARLY TAVR: Evaluation of TAVR Compared to Surveillance for Patients With Asymptomatic Severe Aortic Stenosis

This is a prospective, randomized, controlled, multicenter study. Patients will be randomized to receive either transcatheter aortic valve replacement (TAVR) with the Edwards SAPIEN 3 / SAPIEN 3 Ultra THV or clinical surveillance. Patients will be stratified by whether they are able to perform a treadmill stress test. Patients who have a positive stress test will be followed in a registry to collect data on subsequent treatment and mortality, as applicable.
