What participants receive

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

  • PTMA (Percutaneous Transvenous Mitral Annuloplasty) ImplantDevice

    Percutaneous access from right or left subclavian vein, diagnostic assessment, then placement of the PTMA implant in the coronary sinus, great cardiac vein.

Study groups in NCT00571610
Study groupRoleWhat they receive
1ExperimentalPatient is screened for study and given baseline assessments. Patient receives a diagnostic PTMA assessment and if responsive, receives a PTMA implant.
Receives: Device: PTMA (Percutaneous Transvenous Mitral Annuloplasty) Implant

What is being measured

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

  1. percent of patients who remain free from device-related major adverse events (death, myocardial infarction, tamponade, emergent cardiac surgery

    Measured: 30 days

Secondary outcomes (2)
  1. percent of implanted patients who maintain a sustained 1 grade reduction in MR and reduction of mitral annulus anterior posterior dimension

    Measured: 30 days

  2. percent of implanted patients who exhibit improvement of clinical symptoms as one of the following: decrease in NYHA class, improvement of Minnesota QOL survey, increase exercise capacity 6 minute walk or improvement in VO2 max

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PTMA (Percutaneous Transvenous Mitral Annuloplasty) Implant in people with Heart Failure and Mitral Regurgitation, run by Viacor at 1 site in Canada.

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 3 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 6 Nov 2008. 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 Canada. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 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?

percent of patients who remain free from device-related major adverse events (death, myocardial infarction, tamponade, emergent cardiac surgery (time frame: 30 days). 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 NCT00571610, 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 6 Nov 2008.
