About this study

Official title: Feasibility Study of Percutaneous Aortic Valve Implantation With the Medtronic CoreValve System for Percutaneous Aortic Valve Replacement (PAVR) in Patients With a Failing Previously Surgically Implanted Aortic Bioprosthesis and Presenting a High Risk for Repeat Surgical Valve Replacement

The proposed investigation is a prospective, multicenter, non-randomized study to evaluate the immediate benefits (at discharge and at 30 days) in terms of performance and safety of the implantation of the Medtronic CoreValve PAV in a failing aortic bioprosthesis. In addition, the study aims to evaluate the performance and the safety of the implantation of the Medtronic CoreValve PAV in a failing aortic bioprosthesis at subsequent annual follow-ups out to 48 months post procedure.

These objectives will be achieved through the following endpoints:

  • Primary safety endpoint - Composite of Major Adverse Events
  • Primary performance endpoint - Technical and procedural success at discharge

Patient Population: Eligible subjects will be at least 75 years old, presenting with a failing aortic bioprosthesis (stenotic, incompetent or mixed) including homograft or stented or stentless heterograft, considered poor surgical candidates and necessitating repeat aortic valve replacement. Up to 20 patients will be included in up to four hospitals.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of MAE Free Subjects

    Percentage of subjects without a composite major adverse event (MAE) at 30 days post procedure. the composite MAE includes:

    1. MACCE (Major Adverse Cardiac or Cerebral Event): cardiac death, documented Mobitz type II second degree and third degree atrioventricular block, neurological events and surgical aortic valve replacement.
    2. MAE: non cardiac death including sudden unexpected or unexplained death, cardiac tamponade, nonstructural valve dysfunction resulting in stenosis or regurgitation at the study valve not intrinsic to the valve itself, structural valve deterioration cardiogenic shock, operated valve endocarditis, valve thrombosis, aortic dissection/perforation, major bleeding event, peripheral embolic event and emergent revascularization procedure.

    Measured: 30 days post-procedure

  2. Technical Success.

    The number of subjects in whom technical success was achieved where technical success was defined based on the device functionality as judged by the investigator adressing the ability of the system (1) to access the failing bioprosthetic valve via a peripheral vessel with the delivery catheter and (2) to deploy the valve accurately across the failing bioprosthetic valve and (3) to remove intact delivery system.

    Measured: 30 days post procedure

Questions about this trial

What is this clinical trial studying?

A study testing Medtronic CoreValve System in people with Aortic Valve Stenosis, run by Medtronic Cardiac Rhythm and Heart Failure at 3 sites in 2 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 20 inclusion and 14 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 31 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Germany, Netherlands. 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 31 Jan 2019). 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?

Percentage of MAE Free Subjects (time frame: 30 days post-procedure). The study lists 2 primary outcomes in all. 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 31 Jan 2019; AzTrials last refreshed its copy on 28 Oct 2026.
