About this study

Official title: Coronary Artery Bypass Graft Surgery Combined Pedicled Omentum Wrapped Autologous Atrial Tissue Patch Cardiomyoplasty for Patients With Ischemic Cardiomyopathy: a Prospective Randomized Controlled Clinical Trial

The purpose of this study is in a phase I/II safety and efficacy study to evaluate the clinical effect of coronary artery bypass graft (CABG) combined pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty for patients with ischemic cardiomyopathy.

Read the detailed description

This is a phase I/II, randomized controlled trial to evaluate the use of CABG combined pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty for patients with ischemic cardiomyopathy. The study hypothesis is that the combined surgical technique to perform pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty as adjunct to CABG, is safe to patients with severe ischemic heart failure and can improve regional myocardial perfusion contractility, which resulting in improved systolic and diastolic left ventricular function.

The primary object of this study will be to evaluate the safety and efficacy of this novel combined surgical technique. The efficacy will be assessed changes in left ventricular ejection fraction by MRI. The secondary endpoint of the study is to assess the effects of this novel combined surgical technique on cardiac contractile function and functional outcome. The effects will be assessed on the basis of clinical status and imaging rests in 6 month follow-up after enrollment. A maximum of 60 patients between 20 and 70 years will be enrolled in the study. These participants will be randomized to receive CABG, pedicled omentum graft combined CABG, or pedicled omentum graft autologous atrial tissue patch cardiomyoplasty combined CABG. The objective evaluations will be performed at baseline and during 6 months follow-up.

Being tested
CABG combined cardiomyoplasty, CABG combined pedicled omentum graft, CABG alone

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CABG combined cardiomyoplasty, CABG combined pedicled omentum graft and CABG alone in people with Ischemic Cardiomyopathy and Congestive Heart Failure, run by China National Center for Cardiovascular Diseases at 2 sites in China.

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 9 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 10 Dec 2009. 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 China. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of CABG combined pedicled omentum wrapped autologous atrial tissue transplantation. (time frame: 6 months). The study lists 2 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 Dec 2009; AzTrials last refreshed its copy on 8 Nov 2026.
