About this study

This is post-market clinical follow-up study on 25 consecutive patients in two centers to evaluate the safety and performance of magnetic resonance imaging conditional guide wire and the acceptability of identified risks in the clinical evaluation and to detect emerging risks on the basis of factorial evidence.The procedure will be done in patients with a clinical indication for cardiac magnetic resonance and conventional catheterisation.

Read the detailed description

This is post-market clinical follow-up study on 25 consecutive patients in two centers to evaluate the safety of a guide wire conditional for use in magnetic resonance imaging and the acceptability of identified risks in the clinical evaluation and to detect emerging risks on the basis of factorial evidence.

The guidewire is used to access the patients central circulatory system and in particular for the introduction and exact placement of a pressure catheter to measure the pressure gradient over the aortic arch. The procedure will be done in patients with a clinical indication for cardiac magnetic resonance and conventional catheterisation.Patients need to have a body weight over 40 kg and the introduction of a 5 French catheter should be possible. The primary endpoint is the measurement of procedural success, defined as successful insertion, steerability and visibility in MRI, in the absence of device related adverse events such as damage to vessel wall. In addition structural integrity of the instruments is to be assessed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • pressure gradient measurementProcedure or surgery

    Also called MRWire

    A guidewire is used to introduce and position a pressure catheter under magnetic resonance guidance to conduct flow and pressure measurement in the aortic arch to evaluate vascular resistance.

Study groupRoleWhat they receive
pressure gradient measurementOtherDiagnostic procedure to measure pressure gradient in series of patients. Focus is on safety and absence of adverse events
Receives: Procedure: pressure gradient measurement; Device: MRWire

What is being measured

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

  1. Procedural success

    procedural success means that insertion, steerability and visibility of the guide wire in the MR guided intervention was successfully reached, in the absence of adverse events up to 30 days after procedure

    Measured: Up to 30 days after procedure

Questions about this trial

What is this clinical trial studying?

A study testing pressure gradient measurement and MRWire in people with Congenital Heart Defect, run by Nano4Imaging GmbH 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 3 inclusion and 6 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 30 Mar 2018. 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, United Kingdom. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Procedural success (time frame: Up to 30 days after procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02493634, which also lists 3 linked publications.

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 30 Mar 2018.
