Junctional ectopic tachycardia after congenital heart surgery in the current surgical era . To determine the incidence of postoperative junctional ectopic tachycardia ( JET ) in a modern cohort of pediatric patients , evaluate possible risk factors for JET , and examine the effects of JET on postoperative morbidity and mortality . JET is common after congenital heart surgery . JET-related mortality has been a rare event at our center , which is different from previous reports . We reviewed records for pediatric patients who had postoperative arrhythmias between January 2006 and June 2010 at a large tertiary-care children 's hospital . We performed a matched case-control study to identify risk factors for JET and a matched-cohort study to compare outcomes between patients and controls . Whenever possible , each JET case was randomly matched to two controls on the basis of lesion , repair , and surgical period . We identified 54 patients with JET ( incidence = 1.4 % ) . After multivariate logistic regression analysis , low operative weight , cardiopulmonary bypass ( CPB ) duration > 100 min , and immediate postoperative serum lactic acid level > 20 mg/dl were associated with increased odds of developing JET . Patients with JET had longer mechanical ventilation time , cardiac intensive care unit ( CICU ) stay , and hospital stay . There was only one death in JET group ( 1.8 % ) with no significant difference compared with the control group . JET remains a relatively common postoperative arrhythmia , but it is less frequent than previously reported . JET occurs more commonly in smaller patients with longer CPB runs and significant postoperative lactic acidosis levels . Mortality associated with JET is lower than historically reported , but morbidity remains high .
