Objective:Extracorporeal membrane oxygenation (ECMO) is used to provide cardiorespiratory support during cardiopulmonary resuscitation (extracorporeal cardiopulmonary resuscitation; ECPR) unresponsive to conventional methods. In this study, the results of ECPR in a cardiac arrest setting after cardiac surgery in children were analyzed.Methods:In this retrospective cohort study, between November 2010 and June 2014, 613 congenital heart operations were performed by the same surgical team. Medical records of all the patients who experienced cardiac arrest and ECPR in an early postoperative period (n=25; 4%) were analyzed. Their ages were between 2 days and 4.5 years (median: 3 months). Sixteen patients had palliative procedures. In 88% of the patients, cardiac arrest episodes occurred in the first 24 h after operation. Mechanical support was provided by cardiopulmonary bypass only (n=10) or by ECMO (n=15) during CPR.Results:The CPR duration until commencing mechanical support was <20 min in two patients, 20–40 min in 11 patients, and >40 min in 12 patients. Eleven patients (44%) were weaned successfully from ECMO and survived more than 7 days. Five of them (20%) could be discharged. The CPR duration before ECMO (p=0.01) and biventricular physiology (p=0.022) was the key factor affecting survival. The follow-up duration was a mean of 15±11.9 months. While four patients were observed to have normal neuromotor development, one patient died of cerebral bleeding 6 months after discharge.Conclusion:Postoperative cardiac arrest usually occurs in the first 24 h after operation. ECPR provides a second chance for survival in children who have had cardiac arrest. Shortening the duration of CPR before ECMO might increase survival rates. (Anatol J Cardiol 2017; 17: 328-33)

Background: Single-stage biventricular repair remains a challenging and difficult decision in high-risk newborns and early infants with the presence of left ventricular outflow tract obstruction (LVOTO) or borderline hypoplasia of the left ventricle (LV). Methods: Six high-risk patients underwent the initial hybrid procedure (bilateral pulmonary banding + ductal stenting) for staged biventricular repair. Their median age was 17 days (range: 7-55 days). The diagnosis was interrupted aortic arch (IAA), ventricular septal defect (VSD), and LVOTO (n = 3); IAA and VSD (n = 1); and aortic annular hypoplasia, aortic arch hypoplasia, VSD, and LVOTO (n = 1). The last patient had borderline LV with large atrial septal defect (ASD) and aortic arch hypoplasia. The patient with borderline LV had also ASD closure with small fenestration. Results: One patient died of sepsis after the hybrid procedure. Other patients underwent biventricular repair 8 to 13 months later. Three patients had conventional repair with conal septum resection. The other patient with IAA, in whom LVOTO was considered nonresectable, underwent Yasui operation. The last patient with borderline LV had enough development of left heart structures during follow-up and underwent aortic arch repair. One patient who had conal septum resection died after biventricular repair. One patient needed a tracheostomy; four patients were discharged uneventfully and their clinical conditions were good on postoperative year 1. Conclusion: Staged biventricular repair with the initial hybrid procedure may be a feasible and safe alternative in high-risk neonates and early infants. Hybrid intervention may provide the development of cardiac structures in time and a better evaluation for the possibility of biventricular repair in borderline patients.
