About this study
Official title: A Prospective Study Using Intra-Pericardial Amiodarone for the Prevention of Postoperative Atrial Fibrillation (POAF) in Patients Undergoing Cardiac Arterial Bypass Grafting and/or Valve Surgery
The purpose of this study is to evaluate the combination of CardiaMend, with the addition of amiodarone in the prevention of postoperative atrial fibrillation (POAF) in patients undergoing cardiac arterial bypass grafting (CABG) or valve surgery.
Read the detailed description
This study involves using CardiaMend, an FDA cleared (K210331) pericardial reconstruction matrix with the addition of amiodarone, an FDA approved antiarrhythmic drug, as a prevention of post operative atrial fibrillation.
This is a single-center, prospective randomized study enrolling adult subjects undergoing isolated cardiac arterial bypass or valve surgery, via complete median sternotomy.
CardiaMend will be used according to the Instructions for Use, and then patted dry to facilitate implantation. Four ampules of amiodarone (150mg/3ml; 12cc total volume) will be drawn into a syringe. 2cc will be dripped over the right atrium and a small CardiaMend patch placed to cover this area. Another 2cc will be used over the left atrium and covered with the CardiaMend. The anterior pericardial space will be closed without putting pressure on the underlying structures using the CardiaMend attached to the native pericardium utilizing running 4-0 monofilament suture. A small edge may be left open for drain placement and a small slit for the Left Internal Mammary Artery (LIMA) in case of CABG. The remaining 8 cc of amiodarone will be instilled to the closed pericardial space.
Patients will have continuous electrocardiogram (EKG) until discharge. If clinically indicated, patients will receive a monitor for home monitoring per standard of care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CardiaMend in Combination with AmiodaroneCombination product
The first three patient will receive 600 mg amiodarone into the intact pericardial space. Amiodarone serum levels will be tested at post operative days 2 and 6. The study will only proceed if there is a serum amiodarone level less than 25% of the normal therapeutic level. This should insure lack of systemic toxicity. After the first 3 patients have demonstrated low amiodarone blood levels, a total of up to 60 patients will be enrolled in the study.
The CardiaMend patch will saturated per the instructions and be sutured into place. Amiodarone will be dripped directly over the heart.
| Study group | Role | What they receive |
|---|---|---|
| CardiaMend Pericardial and Epicardial Reconstruction Matrix used in combination with amiodarone | Experimental | Patients randomized to this study arm includes the CardiaMend which will be used according to the instructions for use. It will be patted dry to facilitate implantation. Pieces will be cut to cover the right and left atria. The remaining piece will be contoured to close the anterior pericardial space. Four ampules of amiodarone (150mg/3ml; 12cc total volume) will be drawn into a syringe. 2cc will be dripped over the right atrium and a small CardiaMend patch placed to cover this area. Another 2cc will be used over the left atrium and covered with the CardiaMend.

| University of Chicago's standard of care in patients undergoing isolated CABG or valve surgery | No intervention | The standard of care for this study at The University of Chicago is to ligate the left atrial appendage (LAA) during the proposed cardiac surgery (intra-operative) to reduce the occurrence of post operative atrial fibrillation (A-FIB) in combination with amiodarone injections (if applicable). |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post Operative Atrial Fibrillation
The patients have continuous electrocardiogram (EKG) monitoring until discharge to evaluate for any evidence of atrial fibrillation or atrial flutter which lasts longer than one hour or if less than one hour, requires medical or procedural intervention. Evidence of atrial fibrillation or atrial flutter will be confirmed by 12 lead electrocardiogram by loss or changes to the P wave, as well as irregularities in the QRS wave interval, heart rhythm, or rate. If clinically indicated, patients will receive a monitor for home monitoring per standard of care.
Measured: Through discharge, an average 7 days to 2 weeks
Secondary outcomes (1)
Additional Hospital Time Required Due to Atrial Fibrillation/Flutter
Burden of atrial fibrillation as defined by additional treatment regimen, additional time in intensive care unit (ICU), complications directly associated with atrial fibrillation
Measured: Through discharge, an average 7 days to 2 weeks

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 7 inclusion and 13 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: looking for participants now, as of the sponsor's last update on 2 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Contact Valluvan Jeevanandam, MD (773-702-2500, jeevan@bsd.uchicago.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post Operative Atrial Fibrillation (time frame: Through discharge, an average 7 days to 2 weeks). 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 NCT06063538, which also lists 14 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 2 Mar 2026.
