About this study

The purpose of this study is to gather clinical information on the hemodynamic performance of the Contour 3D® and Tri-Ad® Tricuspid Annuloplasty Rings in a post-market environment.

Read the detailed description

The primary goal of the TV repair procedure is to relieve patients from TV insufficiency or reduce TV stenosis. This study will evaluate the hemodynamic efficacy of the Contour 3D® and Tri-Ad® ring and characterize the effect of the TV repair through assessment of right atrial size and right ventricular function. Additionally, this study will characterize the patient population for whom a Contour 3D® or Tri-Ad® ring is chosen to repair TV insufficiency. Health status and adverse events (AE) will be assessed.

Questions about this trial

What is this clinical trial studying?

An observational study of Tricuspid Valve Regurgitation and Tricuspid Valve Insufficiency, run by Medtronic Cardiovascular at 3 sites in United States.

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 11 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 10 May 2017. 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 United States. 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 10 May 2017). 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?

Change in the Degree of Tricuspid Regurgitation (time frame: Preimplant through Discharge). The study lists 12 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 10 May 2017.
