RESUMEN
BACKGROUND: Berlin Heart EXCOR (BH) ventricular assist devices provide mechanical long-term circulatory support in children with end-stage heart failure, as a bridge to transplantation or to recovery. Most studies are from large-volume paediatric cardiac centres. AIM: The aim of this study was to analyse the experiences of three French centres and to compare these with available published data. METHOD: We performed a retrospective observational study of three paediatric cardiac intensive care units. All children supported with BH devices were included. Morbidity and mortality data were collected and risk factors analysed. RESULTS: Fifty-four (54) patients (54% male) were included. Survival rate was 73% while on a BH device. Median age at BH device implantation was 17 months (range 2-180 months). The predominant indication was dilated cardiomyopathy (61%). Bi-ventricular assist device was used in 25 (46%) cases. The total length of long-term circulatory support was 3,373 days, with a mean length per patient of 62.5 days (range 5-267 days). Thirty-two (32) patients were transplanted (59%) and seven (13%) were successfully weaned. Type and length of support did not influence morbidity. Main complications were renal dysfunction (57%), bleeding (41%), and infection (39%). In multivariate analysis, a weight <5 kg was significantly associated with higher mortality. CONCLUSIONS: The weight seems to be the most important risk factor of mortality in this precarious condition.

OBJECTIVES: Extracorporeal membrane oxygenation has become a gold standard in treatment of severe refractory circulatory and/or pulmonary failure. Those procedures require gathering of competences and material. Therefore, they are conducted in a limited number of reference centers. Emergent need for such treatments induces either hazardous transfers or a mobile pediatric extracorporeal membrane oxygenation team able to remote implantation and transportation. The aim of this work is not to focus on pediatric extracorporeal membrane oxygenation outcomes or indications, which have been extensively discussed in the literature. This study would like to detail the implementation, safety, and feasibility, even in a middle-size pediatric cardiac surgery reference center. PATIENTS: This is a retrospective analysis of a series of patients initiated on extracorporeal membrane oxygenation in a peripheral center and transferred to a reference center. The data were collected from 10 consecutive years: from 2006 to 2016. RESULTS: A total of 57 pediatric patients with a median weight of 6.00 (3.2-14.5) kg and median age of 2.89 (0.11-37.63) months were cannulated in peripheral center and transported on extracorporeal membrane oxygenation. We did not experience any adverse event during transport. The outcomes were comparable to our literature-reported on-site extracorporeal membrane oxygenation series with 42 patients (74%) weaned from extracorporeal membrane oxygenation and a 30-day survival of 60%. Neither patient's age nor weight, indication for extracorporeal membrane oxygenation or length of transport, was statistically significant in terms of outcomes. CONCLUSION: Offsite extracorporeal membrane oxygenation implantation and ground or air transport for pediatric patients on extracorporeal membrane oxygenation appeared to be safe when performed by a dedicated and experienced team, even within a mid-size center.

Over recent decades, specialized paediatric cardiac intensive care has emerged as a central component in the management of critically ill, neonatal, paediatric and adult patients with congenital and acquired heart disease. The majority of high-volume centres (dealing with over 300 surgical cases per year) have dedicated paediatric cardiac intensive care units, with the smallest programmes more likely to care for paediatric cardiac patients in mixed paediatric or adult intensive care units. Specialized nursing staff are also a crucial presence at the patient's bedside for quality of care. A paediatric cardiac intensive care programme should have patients (preoperative and postoperative) grouped together geographically, and should provide proximity to the operating theatre, catheterization laboratory and radiology department, as well as to the regular ward. Age-appropriate medical equipment must be provided. An optimal strategy for running a paediatric cardiac intensive care programme should include: multidisciplinary collaboration and involvement with paediatric cardiology, anaesthesia, cardiac surgery and many other subspecialties; a risk-stratification strategy for quantifying perioperative risk; a personalized patient approach; and anticipatory care. Finally, progressive withdrawal from heavy paediatric cardiac intensive care management should be institutionalized. Although the countries of the European Union do not share any common legislation on the structure and organization of paediatric intensive care or paediatric cardiac intensive care, any paediatric cardiac surgery programme in France that is agreed by the French Health Ministry must perform at least '150 major procedures per year in children' and must provide a 'specialized paediatric intensive care unit'.
