About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

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).

Disqualifiers

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

Trial population

The study population is any patient with no history of atrial arrhythmia scheduled to undergo cardiac surgery and meets other inclusion/exclusion criteria). Each Site: * Approximately 10 Patients from either Tulane Medical Center and/or University Medical Center New Orleans. * Approximately 40 Patients from Washington University Medical Center (Barnes Jewish Hospital). The PIs and co-PI will have access to recruit patients through their cardiology and cardiothoracic surgery clinics. Participants may also be recruited from the community by direct advertising; emails, TV, flyers posted in public places, as well as online postings to study-site affiliated websites, social media platforms (Facebook, Twitter, Instagram) and LinkedIn.

Trial outcomes

Primary outcomes

1

Incidence of atrial arrhythmia in patients after cardiac surgery

The incidence of any atrial arrhythmia (atrial fibrillation, atrial flutter, atrial tachycardia etc.) from after their surgical procedure to their discharge from the hospital. Atrial arrhythmia is defined as any abnormal atrial rhythm episode continuing for more than 30 seconds, starting immediately after the patient arrives at the post-operation ICU. All atrial arrhythmia starting after the operation will be monitored and recorded. This will be measured using continuous telemetry and/or serial ECG monitoring.

Time frame
2 weeks

Secondary outcomes

1

Rate of in-hospital mortality

In-hospital mortality is defined as patient death during any point of hospital stay following cardiac surgery. This will be measured through patients medical chart review.

Time frame
2 weeks
2

Hospital and Intensive Care Unit (ICU) length of stay (LOS)

LOS is defined as duration from admission to discharge in days in the hospital and ICU. This will be measured through patients medical chart review.

Time frame
2 weeks
3

Incidence of stroke

Stroke is defined as sudden loss of brain function caused by an interruption of blood supply to the brain either through an ischemic or hemorrhagic modality. This will be measured through patients medical chart review.

Time frame
2 weeks
4

Incidence of acute respiratory failure

Acute respiratory failure is any decrease in respiratory function resulting in hypoxemia (low arterial oxygen levels), hypercapnia (elevated levels of carbon dioxide gas) or a combination of the two. This will be measured through patients medical chart review.

Time frame
2 weeks
