Baseline Atrial Fibrosis Predicts Risk for Post-operative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
United States50 participantsStarted 2021-11-21
Plain-language summary
The study aims to evaluate and compare the incidence of atrial arrhythmias (including Post-Operative Atrial Fibrillation (POAF), atrial flutter, and atrial tachycardia) stratified by baseline Utah fibrosis stages and overall fibrosis (%) of the left atrial wall area. The investigators hypothesize that patients with a higher baseline Utah fibrosis staging will experience a higher incidence of POAF.
The study also aims to evaluate and compare the in-hospital mortality, length-of-stay (LOS), complication rates (strokes, pneumonia, respiratory failure etc.) of the different Utah fibrosis stage cohorts. Perform cost analysis and compare between patients with POAF and patients without POAF. The investigators hypothesize that patients experiencing POAF will have a higher mortality rate, longer LOS, greater complications, and therefore, additional hospital costs.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Male or female patients age 40 years of age or older
* Patients with no history of atrial arrhythmia (atrial fibrillation, atrial flutter, atrial tachycardia) scheduled to undergo cardiac surgery (These surgeries include but are not limited to coronary artery bypass graft (CABG), valvular repair/reconstruction, aneurysm repair, and insertion of pacemaker).
Exclusion Criteria:
* Patients with a history of atrial arrhythmia (atrial fibrillation, atrial flutter, atrial tachycardia)
* Patients with a history of cardiac or open chest surgery
* Patients with a history of catheter ablation
* Patients under the age of 40
* Patients with left ventricular assist device (LVAD) or scheduled to have LVAD implanted
* Patients who have previously undergone extracorporeal membrane oxygenation (ECMO)
* Patients who have undergone or will undergo heart transplantation
* Patients with any health related Late Gadolinium Enhancement (LGE)-MRI contraindications (including previous allergic reaction to gadolinium, pacemakers, defibrillators, other devices/implants contraindicated for MRI)
* Acute or chronic severe renal disease with a low glomerular filtration rate (GFR), \<30 mL per minute per 1.73 m2 will be excluded from the trial. (A creatinine measurement should be available within the last 6 months. If not, a creatinine blood test will be drawn to assess for renal function before the MRI acquisition).
* Patients weighing \> 300 lbs. (MRI image quality decreases due to…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
