Summary
Brief summary
The study objective is to demonstrate that the safety and effectiveness of the Medtronic TAVR
system as measured by rates of all-cause mortality or disabling stroke at two years is
noninferior to SAVR in the treatment of severe aortic stenosis in subjects who have a low
predicted risk of operative mortality for SAVR.

The purpose of the expanded use addendum to the Medtronic TAVR in Low Risk Patients Trial
protocol is to conclude the randomized phase of the trial and initiate the single-arm,
non-randomized, continued access phase of the trial.
