Numeric variables are presented as median with interquartile range. Singly or in association with atrial septal defect and/or patent ductus arteriosus. †Singly or in association with patent ductus arteriosus. ǁ cm are generally associated with heightened pulmonary vascular resistance in pediatric patients with unrestrictive cardiac communications [14, 15]. ‡Tricuspid annular plane systolic excursion. Normally, values increase with increasing age in the pediatric population. A TAPSE of ≥15.5 is considered normal at the age of 1 year, as are by the age of 2 years [16]. § versus pre-CPB levels, Wilcoxon test.
