About this study

Official title: Engager Direct Aortic Clinical Study: Medtronic Engager™ Transcatheter Aortic Valve Implantation System Via Direct Aortic Approach

To confirm the safety and performance of the Medtronic Engager™ Transcatheter Aortic Valve Implantation System via direct aortic approach.

Read the detailed description

To confirm the safety and performance of the Medtronic Engager™ Transcatheter Aortic Valve Implantation System via direct aortic approach in patients with symptomatic severe aortic valve stenosis at high or extreme risk for surgical aortic valve replacement for which treatment via direct aortic access is preferred.

Questions about this trial

What is this clinical trial studying?

A study testing Engager™ aortic valve in people with Aortic Valve Stenosis, run by Medtronic Cardiac Rhythm and Heart Failure at 6 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Germany, United Kingdom, Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Jul 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acute Delivery System Success (time frame: Within 30 days of implant procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jul 2018.
