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

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.
