What participants receive

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

  • HeparinDrug

    Also called Unfractioned heparin

    Valvuloplasty is performed in a conventional manner, ie with an injection of unfractionated heparin (50 IU / kg) at the start of procedure

  • NaClDrug

    Also called placebo

    valvuloplasty is performed without heparin (placebo injection)

What is being measured

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

  1. Number of serious complication : vascular, hemorrhagic or ischaemic complication

    Measured: Up to10 days after the valvuloplasty (D1-D10 after the intervention)

Secondary outcomes (2)
  1. Number of any non serious complication directly associated with the procedure (vascular, hemorrhagic or ischaemic complication)

    Non serious complication is complication directly associated with the valvuloplasty which could be vascular complications medically treated (compression), BARC 2 hemorrhage, general procedure complications

    Measured: up to30 days after the valvuloplasty (until D30 after intervention)

  2. number of a serious complication : vascular, hemorrhagic or ischaemic complication

    Measured: up to 30 days after valvuloplasty

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Heparin and NaCl in people with Aortic Stenosis, Non-rheumatic, run by University Hospital, Montpellier at 1 site in France.

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 4 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 12 Jun 2026. 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 France. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Difficulty of inclusion). 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?

Number of serious complication : vascular, hemorrhagic or ischaemic complication (time frame: Up to10 days after the valvuloplasty (D1-D10 after the intervention)). 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 NCT01823393, which also lists 1 linked publication.

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 12 Jun 2026.
