Transoesophageal echocardiography for prediction of postoperative atrial fibrillation after isolated aortic valve replacement: Two-dimensional speckle tracking for intraoperative assessment of left ventricular longitudinal strain

摘要

OBJECTIVES: Recent studies suggested association between impaired left ventricular long-axis function and arrhythmic events early after open heart surgery. This prospective study investigated the predictive value of a depressed intraoperative global longitudinal strain (GLS) for postoperative atrial fibrillation after isolated aortic valve replacement in patients with preserved ejection fraction.
