↵a p < 0.001,
↵b p < 0.01 and
↵c p = 0.02 to 0.05 compared with patients without JT. AO = aortic; ASD = atrial septal defect; AV = atrioventricular; Caval-PA shunt = caval to pulmonary shunt (Glenn and variants); CAVC = common atrioventricular canal; Coarct/arch = coarctation and other aortic arch surgery; PA = pulmonary artery; P valve/art = pulmonary valvular or arterial repair or plasty; P vein = total or partial anomalous pulmonary venous return; PDA = patent ductus arteriosus; Syst-PA shunt = systemic to pulmonary arterial shunt; TOF = tetralogy of Fallot and variants; TGA/IVS = atrial (n = 46) or arterial (n = 335) switch for transposition with intact ventricular septum; TGA/VSD = atrial (n = 6) or arterial (n = 192) switch for transposition plus closure of ventricular septal defect; VSD = membranous or muscular ventricular septal defect.
