Assessment of Atrial Cardiomyopathy Using MRI as a Predictor of Cardiac Post-Operative Atrial Fibrillation After Cardiac Surgery. (IRM-FAPO)

After cardiac surgery, there is a high prevalence of postoperative atrial fibrillation (POAF). However, its diagnostic and therapeutic management is poorly codified.

This pathology is caused by atrial abnormalities which form the concept of atrial cardiomyopathy.

New tools affording to itemize the atrial cardiomyopathy are needed. Indeed, current tools, as echocardiography and electrocardiogram are relevant but only lead to a raw evaluation of the atrial cardiomyopathy. MRI, because of the assessment of the atrial fibrosis by late gadolinium assessment (LGE) and 4D flow magnetic resonance imaging (MRI) could be relevant to specify the atrial cardiomyopathy.

Study Overview

Detailed Description

The aim of the study is to evaluate the atrial cardiomyopathy, assessed by magnetic resonance imaging (MRI), as a predictor of postoperative atrial fibrillation (POAF) after with coronary artery bypass graft surgery .

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Coronary Artery Bypass Grafting

Patient with indication of Coronary Artery Bypass Grafting will be included. They will have:

  • before surgery : cardiac Magnetic Resonance Imaging (MRI), Blood sample
  • during surgery : Cardiac muscle biopsy
  • after surgery : Holter-electrocardiogram (ECG), medical examination
Cardiac magnetic resonance imaging (MRI) will be realized before Coronary Artery Bypass Grafting for assess atrial cardiomyopathy.
Other Names:
  • 4D flow Magnetic Resonance Imaging with Late Gadolinium Enhancement
Blood sample will be realized (4 tubes of 4ml blood, 16ml in total) before Coronary Artery Bypass Grafting.
Cardiac muscle biopsy will be realized during Coronary Artery Bypass Grafting.
Holter-electrocardiogram (ECG) will be realized 1 year after Coronary Artery Bypass Graftin during 3 days to diagnose the occurrence of atrial fibrillation.
medical examination will be realized 1 year after Coronary Artery Bypass Graftin. Theses datas will collected: events during the follow-up year and evaluation of the Holter-electrocardiogram result.
