  • Adult, Older adult

Who may be able to join

  • Subjects are capable of giving informed consent.
  • Age 19-89

Show all 10Show fewer
  • LVAD explantation
  • Valve replacement or repair
  • Catheterization and myocardial biopsy for idiopathic cardiomyopathy
  • Coronary artery bypass graft (CABG)

Who cannot join

  • Life expectancy less than 2 weeks
  • Diagnosed with following co-morbidities: cancer, chronic kidney disease (GFR≤30 or serum creatinine >2.1), active infection or treatment with antibiotics or persistent infectious disease (hepatitis, HIV, etc), cirrhosis, active substance abuse and/or alcohol dependence (≥ 14 alcoholic beverages per week).
  • Control Myocardial Tissue from Donor Hearts Inclusion Criteria
  • Samples collected from non-failing hearts deemed unsuitable for transplantation by TransLife because of either acute recipient issues or post-harvest evidence of pathology or positive but benign serology.
  • Normal cardiac function from medical records
  • Pathological remodeling and extensive infarction with limited non-pathological regions of myocardium.
  • Abnormal or impaired cardiac function from medical records, which are self determinants for rejection as a donor organ.

What participants receive

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

  • Collection of discarded heart tissueProcedure or surgery

    Discarded heart tissue will be collected from patients undergoing the aforementioned cardiac surgeries.

Study groups in NCT03032627
Study groupRoleWhat they receive
Cardiac surgeryOtherSubjects will be recruited by a coordinator through electronic medical record (EMR) searches to identify those undergoing left ventricle assist device (LVAD) implantation and explantation, heart transplant, valve replacement or repair, endomyocardial biopsy during catheterization, and arterial bypass surgery. Prior to the procedure, potential subjects will be informed about the clinical study and if interested, they will be consented.
Receives: Procedure: Collection of discarded heart tissue

What is being measured

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

  1. Analyses of collected tissues

    Tissue samples collected during surgery will be analyzed by way of immunoblot and qrtPCR of mRNA for metabolic enzymes on neutralized acid extracts.

    Measured: Restricted to the time around surgical procedure

Where is the study taking place?

The record lists 1 site 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?

This study is still under way. Results are not available in the source record yet.

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?

Analyses of collected tissues (time frame: Restricted to the time around surgical procedure). 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 NCT03032627, which also lists 12 linked publications.

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 13 Mar 2025.
