The median age was 1.2 years (range <1 month to 16.3 years): patients allocated IWBC were, on average, 7 months older than those allocated ICBC (median 11 and 18 months, respectively; Table Demography and intraoperative detailsData missing for 1 patient (ICBC).Other procedures were: ICBC group—double outlet right ventricle and partial anomalous pulmonary venous drainage repair, aortic root replacement, tricuspid valve repair and right ventricular myectomy. IWBC group—repair of double outlet right ventricle and atrioventricular septal defect and atrial switch (hemi-Mustard), tetralogy of Fallot and atrioventricular septal defect repair, mitral valve replacement and Ross-Konno, ventricular septal defect and Ebstein’s repair, pulmonary and tricuspid valve replacement.Two patients (ICBC) withdrew prior to or during surgery.Ranges (minimum–maximum): ICBC: 25–200 min, IWBC 16–292 min.Data missing for 1 patient (IWBC).Data missing for 6 patients (4 ICBC, 2 IWBC).Data missing for 20 patients (13 ICBC, 7 IWBC).Data missing for 2 patients (1 ICBC, 1 IWBC).CPB: cardiopulmonary bypass; ICBC: intermittent cold blood cardioplegia; IQR: interquartile range; IWBC: intermittent warm blood cardioplegia; RACHS: Risk adjustment for Congenital Heart Surgery.
