Atrial Dyssynchrony to Predict Arrhythmias in the Postoperative Setting of Cardiovascular Surgery.

Atrial Electromechanical Alteration as a Predictor of Arrhythmias in the Postoperative Period After Cardiovascular Surgery

Study Type

OBSERVATIONAL

Conditions

Atrial Fibrillation Postoperative Complications

Summary

This study aims to improve the prediction for developing arrhythmias in the postoperative period of cardiovascular surgery by using non-invasive echocardiographic techniques that are sensitive to detect inter and intra-atrial dyssynchrony. The main question it aims to answer is: Do patients with atrial dyssynchrony are at increased risk of developing arrhythmias in the postoperative period of cardiovascular surgery? Patients admitted to the protocol will undergo an echocardiogram with atrial strain before surgery to determine the presence or absence of intra- and inter-atrial dyssynchrony and will be followed during hospitalization to assess the occurrence of atrial fibrillation in the postoperative period.

Plain Language Summary

Simplified for easier understanding

This study is investigating whether a heart ultrasound measurement called atrial dyssynchrony — which reflects how coordinated the upper chambers of the heart are — can predict whether a patient will develop atrial fibrillation (an irregular heartbeat) after non-mitral heart surgery. This type of complication is common and can be serious. **You may be eligible if...** - You are scheduled for heart surgery that does not involve the mitral or tricuspid valve - You are in normal heart rhythm (sinus rhythm) at the time of hospital admission - You have consented to participate in the study **You may NOT be eligible if...** - You are having mitral or tricuspid valve surgery - You have a history of atrial fibrillation - You have congenital heart disease or heart tumors - You are having emergency heart surgery - Your heart ultrasound (echocardiogram) image quality is too poor for assessment Talk to your doctor to see if this trial is right for you.

Interventions

DIAGNOSTIC_TESTAtrial dyssynchrony

To determine interatrial dyssynchrony, an adaptation of the echocardiographic atrial strain will be made so that both atria can be evaluated simultaneously. This new evaluation, OMEGA (ω) will yield the time to maximum deformation of the lateral segments of the right atrium and the lateral segments of the left atrium. Additionally, total atrial deformation will be evaluated via bi-atrial strain analysis. We will then measure the maximum deformation time-from P-wave onset to the maximum negative strain deflection-to assess its relationship with atrial contraction strain.
