About this study

Official title: Randomized Comparison of Transapical Transcatheter Treatment Versus Conventional Surgery in Patients With Native Aortic Valve Stenosis

This study is a randomised comparison of apical stent valve treatment versus conventional valve surgery in patients with severe aortic valve stenosis.

Read the detailed description

The purpose of the study is to compare the new established apical stent valve treatment with conventional surgical intervention using biological valve prostheses in patients with severe aortic valve stenosis.

The Edwards-SAPIENTM Transcatheter Heart Valve (Edwards Lifesciences, Irvine, CA) will be used in the stent valve group. The Carpentier-Edwards-Perimount Heart Valve (Edwards Lifesciences, Irvine, CA) will be recommended for the conventional surgery group.(Edwards Lifesciences, Irvine, CA).

Heart centres in the Nordic region with experience (>10 cases) in apical stent valve treatment and in conventional surgical treatment of high risk patients with aortic valve stenosis. The study will be initiated at Aarhus University Hospital, Skejby, Denmark.

Study hypothesis:

As compared to conventional aortic valve substitution in patients aged >75 years, apical stent valve treatment reduces the rates of death, cerebrovascular insult (CVI) and need of dialysis for renal failure 1 month after the treatment.

Primary clinical end-point:

Combined end-point consisting of death, CVI and/or renal failure with need for haemodialysis, 1 month after index treatment.

    Insertion of a stent valve using catheter-based technique through a mini thoracotomy

  • Conventional Aortic Valve SurgeryProcedure or surgery

    Operation using heart-lung machine, with insertion of a biological artificial heart valve

Questions about this trial

What is this clinical trial studying?

A study testing Transapical Aortic Valve Implantation and Conventional Aortic Valve Surgery in people with Aortic Valve Stenosis, run by Aarhus University Hospital Skejby at 1 site in Denmark.

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 7 inclusion and 7 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: stopped early, as of the sponsor's last update on 1 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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?

The study was stopped early (reason given: By recommendation from the Data and safety monitoring board). Results are not available in the source record.

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?

Death, CVI and/or renal failure requiring any dialysis (time frame: 1 month). 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 1 Jun 2017.
