Abstract:
Intraoperative transesophageal echocardiography is an established modality for confirming the preoperative diagnosis, assess adequacy of surgical repair, identify residual problems, and help improve the outcome after operation. Despite the multitude of advantages, intraoperative transesophageal echocardiography can affect the hemodynamic parameters in small neonates and children. A severe transient electromechanical dissociation caused by the anteflexion of a transesophageal echocardiography probe during a total anomalous pulmonary venous connection repair in an infant is reported.
