Right Atrial Function and Risk of Postoperative Atrial Fibrillation After Heart Bypass Surgery

What this Trial Is About

Postoperative atrial fibrillation POAF occurs in about 30% of patients after cardiac surgery and increases risks such as permanent atrial fibrillation, heart failure, stroke, heart attack, and death. While the role of the left atrium is well known, the role of the right atrium RA in POAF is less understood. This research aims to study whether changes in RA function, measured by right atrial strain RAS using specialized heart ultrasound 2D-STE, are linked to a higher chance of developing POAF after cardiac surgery. Participants in this observational study are adult patients scheduled for planned aortocoronary bypass surgery using a heart-lung machine at Amiens University Hospital. The study uses transthoracic echocardiography to measure RA strain parameters, focusing on the reservoir phase RASr. No treatments or interventions are given instead, data is collected to observe how RA function relates to POAF occurrence. During the 30-month study, researchers will analyze the correlation between variations in the RASr parameter and the incidence of POAF. Patients must have good-quality echocardiographic images for analysis. The study involves monitoring heart function through imaging and collecting relevant medical information without altering standard care. This helps improve understanding of factors contributing to POAF after heart surgery.
