For neonates with critical congenital heart disease, delivery before 39 weeks' gestation is associated with greater mortality and morbidity rates and more resource use. With respect to neonatal mortality, the ideal gestational age for delivery of these patients may be 39 to 40 completed weeks.

Greater preoperative cytokine and CRP production in younger infants did not correlate with postoperative outcomes; correlation between postoperative inflammatory mediator production and clinical course was statistically significant but clinically modest. We conclude that in infants undergoing low-to-moderate-complexity cardiac surgery in a single high-volume center, the contribution of inflammatory mediator production to postoperative morbidity is relatively limited.

We developed a Crisis Resource Management training program in a pediatric cardiac intensive care unit to teach technical resuscitation skills and improve team function. Participants found the experience useful and reported improved ability to function in a code. Further work is needed to determine whether participation in the Crisis Resource Management program objectively improves team function during real resuscitations.

Overall survival to discharge for patients with shunted single-ventricle physiology is similar to survival reported in the Extracorporeal Life Support Organization registry for all infants supported with cardiac extracorporeal membrane oxygenation. Thus, shunted single-ventricle physiology should not be considered a contraindication to extracorporeal membrane oxygenation. Patients cannulated for hypoxemia, particularly shunt thrombosis, had markedly improved survival compared with those supported primarily for hypotension/cardiovascular collapse. Survival did not differ depending on anatomic diagnosis.

Cardiothoracic surgery trainees found a contextualized ECMO cannulation during cardiopulmonary resuscitation cannulation curriculum to be highly useful and demonstrated sustained improvement in time to cannulation, CECS, and GRS. Further work will focus on determining the clinical impact of this training and defining the optimal interval and number of training sessions.

The durability of neonatal right ventricular outflow tract reconstruction is diagnosis and method dependent. Anatomy allowing right ventricular outflow tract patching (either transannular or nontransannular) provides a durability advantage compared with that seen with a homograft. There was no difference in performance between aortic and pulmonary homografts, and the monocusp valve has limited durability and effectiveness in neonatal right ventricular outflow tract surgery. The long-term outcomes of transannular and nontransannular patching techniques for neonatal repair of tetralogy of Fallot/pulmonary stenosis are similar.
