Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults having planned heart bypass surgery (aortocoronary bypass) at Amiens University Hospital. It studies whether right atrium strain on heart ultrasound predicts atrial fibrillation after surgery.

Age
Over 18 years
Sex
All sexes
Disease stage
Planned aortocoronary bypass grafting under cardiopulmonary bypass.
Earlier treatment
No circulatory mechanical assistance before surgery.
Biomarker or test result
Heart ultrasound image quality good enough to measure right atrial strain (RAS).

Main reasons for not taking part

  • History of atrial fibrillation or flutter
  • Valve surgery or ascending aorta surgery
  • Urgent cardiac surgery
  • Tricuspid insufficiency greater than grade 2
  • Left ventricular ejection fraction lower than 50%

About the trial

What the trial wants to find out

The incidence of postoperative atrial fibrillation (POAF) after cardiac surgery is around 30%. POAF increases the risk of developing permanent atrial fibrillation and raises the risk of cardiac decompensation, stroke, acute myocardial infarction, and death. While the role of the left atrium (LAF) in the pathophysiology of POAF is now well-established, the part of the right atrium (RA) remains poorly understood. Recent studies suggest a correlation between RA function and POAF.

RA function can be assessed by transthoracic echocardiography (TTE) with dedicated software for measuring the RA strain (RAS). RA function is thus divided into three phases: reservoir (RASr), conduit, and contraction. Numerous studies have demonstrated that a significant alteration in RAS predicts POAF in various clinical contexts. Therefore, it is essential to investigate whether alterations in RA function assessed by 2D-STE (RAS) are associated with an increased occurrence of FAPO after cardiac surgery.
