Right Ventricular Echocardiographic Predictors of Postoperative Supraventricular Arrhythmias After Thoracic Surgery: A Pilot Study

Lung isolation is associated with acute changes in global right ventricular function. A normal baseline MPI that worsens after lung isolation is a better predictor of postoperative SVT as compared with baseline abnormal MPI that does not worsen after lung isolation. Myocardial performance index has a potential to be used as a right ventricular stress test to tolerate OLV before thoracic surgery.
