Randomized Controlled Trial Comparative StudyJunctional 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. ⋯ 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.

Randomized Controlled Trial Comparative StudyA predictive model for neurodevelopmental outcome after the Norwood procedure.
Neurodevelopmental outcomes after the Norwood procedure for single right ventricular lesions are worse than those in the normal population. It would be valuable to identify which patients at the time of Norwood discharge are at greatest risk for neurodevelopmental impairment later in childhood. As such, this study sought to construct and validate a model to predict poor neurodevelopmental outcome using variables readily available to the clinician. ⋯ When the CART model was applied to 70 subjects from the ISV trial, the correct classification rate was 67 %. This model of variables from the Norwood hospitalization can help to identify infants at risk for neurodevelopmental impairment. However, given the overall high prevalence of neurodevelopmental impairment and the fact that nearly one third of severely affected children would not have been identified by these risk factors, close surveillance and assessment for early intervention services are warranted for all infants after the Norwood procedure.
