Introduction:The neutrophil-lymphocyte ratio (NLR) has been associated with worse outcomes in patients undergoing coronary artery bypass graft surgery. Little is known about this association in the pediatric population who require surgery for congenital heart defects, especially in patients with a single ventricle (SV).Objective: To analyze the association of the preoperative NLR with outcomes in patients undergoing the bidirectional Glenn procedure.Methods: This study involved a retrospective cohort analysis of 141 consecutive patients with SV undergoing the bidirectional Glenn procedure between January 2011 and December 2017 in two centers. The preoperative NLR was included in the last hemogram test before surgery. According to the NLR level, the patients were divided into group I (NLR < 1), group II (NLR between 1 and 2), and group III (NLR > 2).The primary endpoint was total hospital length of stay (LOS), and secondary endpoints were mechanical ventilation (MV) time, intensive care unit (ICU) LOS, ventricular dysfunction, complications, and middle-term mortality.Results: The average follow-up duration was 48 months. There were 61, 47, and 33 patients in groups I, II, and III, respectively. Patients in group III exhibited an increased risk of prolonged total hospital LOS (P = .00). An increase in MV time (P = .03) and ICU LOS (P = .02) was also observed in this group, and these patients experienced greater mortality in 24 months following the surgery (P = .03). There was no association between the NLR and ventricular dysfunction (P = .26) and complications (P = .46). Conclusion:A high preoperative NLR was associated with worse outcomes in patients with SV physiology undergoing the bidirectional Glenn procedure.

An innovative cooperation model between a European and an African centre based on permanent delivery of care and education allowed for effective training of local teams and treatment of children with heart disease in their own environment.

Introduction: Acute kidney injury is a risk factor for chronic kidney disease and mortality after congenital heart surgery under cardiopulmonary bypass. The neutrophil–lymphocyte ratio is an inexpensive and easy to measure biomarker for predicting outcomes in children with congenital heart disease undergoing surgical correction. Objective: To identify children at high risk of acute kidney injury after tetralogy of Fallot repair using the neutrophil–lymphocyte ratio. Methods: This single-centre retrospective analysis included consecutive patients aged < 18 years who underwent tetralogy of Fallot repair between January 2014 and December 2018. The pre-operative neutrophil–lymphocyte ratio was measured using the last pre-operative complete blood count test. We used the Acute Kidney Injury Network definition. Results: A total of 116 patients were included, of whom 39 (33.6%) presented with acute kidney injury: 20 (51.3%) had grade I acute kidney injury, nine had grade II acute kidney injury (23.1%), and 10 (25.6%) had grade III acute kidney injury. A high pre-operative neutrophil–lymphocyte ratio was associated with grade III acute kidney injury in the post-operative period (p = 0.04). Patients with acute kidney injury had longer mechanical ventilation time (p = 0.023), intensive care unit stay (p < 0.001), and hospital length of stay (p = 0.002). Conclusion: Our results suggest that the pre-operative neutrophil–lymphocyte ratio can be used to identify patients at risk of developing grade III acute kidney injury after tetralogy of Fallot repair.

The study shows that VSD is the most common CHD in childhood, the diagnosis is made late and almost half of VSDs are associated with other CHDs.

Submitral aneurysm is not restricted to adults. Heart failure is the commonest clinical presentation in the pediatric age. The transatrial approach is feasible, safe, and associated with good short-term results. The mitral valve can be preserved in the majority of cases.
