aNumber (percentage)—Chi-square test or Fisher’s exact test. bMedian (range)–Mann-Whitney U-test.
BMI, body mass index; Echo., Echocardiogram; ASD, atrial septal defect; EF, ejection fraction; OS-ASD, ostium secundum ASD; sinus-ASD, sinus venosus ASD; OP-ASD, ostium primum ASD; un-ASD, unroofed coronary sinus ASD; ECC, extra-corporeal circulation.
*As 3 children were below 2 years of age this analysis was performed on 29 children with mild PE and 6 children with moderate/severe PE.
