An observational study in Symptomatic Aortic Stenosis, sponsored by Medtronic Cardiovascular. Completed at 60 sites in 12 countries. Per ClinicalTrials.gov, last updated 2026-01-13.
Sponsored by Medtronic Cardiovascular · Observational
The purpose of this study is to collect clinical evidence on valve performance and procedural outcomes associated with an "optimized" TAVR care pathway and post-TAVR conduction disturbance pathway while using the Evolut™ PRO and Evolut™ PRO+ devices.
The purpose of the addendum is to collect post-market clinical evidence on valve performance and procedural outcomes associated with the Evolut FX Device.
This is a post market, multi-center (sites in US/CAN/EMEA/ANZ), prospective, non-randomized study.
The addendum is a post market, multi-center (sites in US only), prospective, non-randomized study.
Medtronic Cardiovascular is the lead sponsor of 66 studies on the registry; 7 are open to participants now.
Of its 5 completed or terminated interventional studies of FDA-regulated products, 5 (100%) have results posted.
Counted across the registry records on this site, refreshed daily.
The study population includes patients with symptomatic native aortic valve stenosis that necessitates valve replacement who meet the criteria for on-label use of the Evolut™ PRO or Evolut™ PRO+ (and FX system for the addendum where applicable) system in accordance with Instructions for Use and local regulations.
