Atrial Dyssynchrony to Predict Arrhythmias in the Postoperative Setting of Cardiovascular Surgery.
Sponsor: School of Medicine. National University of Cuyo
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.

Interventions
Atrial 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.
