About this study

Official title: A 1-year Prospective, Multicenter, Non-Randomized, Observational, Study to Evaluate Optimal Improvement of Vein Graft Patency Long Term by the Implementation of Novel Endoscopic Harvesting Techniques

This is an observational study of lone Coronary Artery Bypass Grafting procedures with endoscopic vein graft harvesting using best harvesting practices.

Read the detailed description

This is a prospective, multi-center, non-randomized, observational study of 100 patients who will undergo routine coronary artery bypass grafting. Eligible candidates will undergo lone Coronary Artery Bypass Graft (CABG) procedures with endoscopic vein harvesting using best harvesting practices, defined as: systemic heparinization prior to vein manipulation, standardization of vein graft harvesting techniques, pressure limiting syringe and 3 month use of dual anti-platelet therapy. Patients will undergo a CT angiography at 30 days and 12 months to assess vein graft patency.

What is being measured

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

  1. Optimal Improvement of Vein Graft Patency Long Term by the Implementation of Novel Endoscopic Harvesting Techniques

    To demonstrate improved vein graft patency rates at 12 months for endoscopically harvest saphenous vein grafts by employment of modifications to existing techniques in vein graft handling during harvests. Vein graft patency will be measured at 30 days post CABG and at one year post CABG as evaluated by cardiac CT angiography or cardiac catheterization.

    Measured: 12 months

Secondary outcomes (1)
  1. OPTION

    To develop a standardized approach for harvesting, handling and preparing vein grafts in the endoscopic approach. By capturing the following:

    1. Incidence of vein graft failure at the time of initial CABG as evaluated by transit time graft flow measurements
    2. Incidence of vein graft failure at post-operative day 30 as evaluated by cardiac CT angiography or cardiac catheterization
    3. Incidence of vein graft failure at each interval (30 day and 12 month) as categorized by:
    4. Harvested vessel
    5. vein graft destinations
    6. vein graft quality

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease, run by Cardiopulmonary Research Science and Technology Institute at 2 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 4 inclusion and 9 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 22 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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?

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?

Optimal Improvement of Vein Graft Patency Long Term by the Implementation of Novel Endoscopic Harvesting Techniques (time frame: 12 months). 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 22 Oct 2014.
