Early nutritional assessment and intervention contribute significantly to its treatment and improve outcomes. Our objective was to develop a consensus document for the nutritional assessment and management of infants with CHD. Material and methods We employed a modified Delphi technique. Based on the literature and clinical experience, a scientific committee prepared a list of statements that addressed the referral to paediatric nutrition units (PNUs), assessment, and nutritional management of infants with CHD. Specialists in paediatric cardiology and paediatric gastroenterology and nutrition evaluated the questionnaire in 2 rounds. Results Thirty-two specialists participated. After two evaluation rounds, a consensus was reached for 150 out of 185 items (81%). Cardiac pathologies associated with a low and high nutritional risk and associated cardiac or extracardiac factors that carry a high nutritional risk were identified. The committee developed recommendations for assessment and follow-up by nutrition units and for the calculation of nutritional requirements, the type of nutrition and the route of administration. Particular attention was devoted to the need for intensive nutrition therapy in the preoperative period, the follow-up by the PNU during the postoperative period of patients who required preoperative nutritional care, and reassessment by the cardiologist in the case nutrition goals are not achieved. Conclusions These recommendations can be helpful for the early detection and referral of vulnerable patients, their evaluation and nutritional management and improving the prognosis of their CHD. Introducción La tasa de desnutrición entre los lactantes con cardiopatías congénitas (CC) es elevada. Una evaluación e intervención nutricional tempranas ayudan a su tratamiento y mejoran el pronóstico. El objetivo fue elaborar un documento de consenso para la evaluación y el tratamiento nutricional del lactante con CC. Material y Métodos Se utilizó una técnica Delphi modificada. En base a la literatura y a su experiencia clínica, un comité científico elaboró un listado de afirmaciones que abordaban la derivación a Unidades de Nutrición Pediátrica (UNP), la evaluación y el manejo nutricional de los lactantes con CC. Especialistas en cardiología pediátrica, y gastroenterología y nutrición pediátrica evaluaron el cuestionario en 2 rondas. Resultados Participaron 32 especialistas. Tras dos rondas de evaluación, se consensuaron 150 de 185 ítems (81%). Se determinaron patologías cardiacas de bajo y alto riesgo nutricional y factores asociados cardíacos o extracardíacos que confieren riesgo nutricional alto. Se elaboraron recomendaciones para la evaluación y seguimiento en unidades de nutrición y sobre el cálculo de los requerimientos nutricionales, el tipo de nutrición y la vía de administración. Se enfatiza la necesidad de un tratamiento nutricional intensivo en el preoperatorio, del seguimiento por la UNP en el postoperatorio cuando se haya necesitado intervención preoperatoria, y de la reevaluación por el cardiólogo cuando no se alcancen los objetivos nutricionales. Conclusiones Estas recomendaciones pueden ser de ayuda para la detección precoz y derivación temprana de población vulnerable, su evaluación y tratamiento nutricional y para mejorar el pronóstico de su CC. The study received funding from Danone Nutricia to support in-person and online meetings of experts.

Resumen Introduccion y objetivos El retrasplante cardiaco (ReTC) representa un tema controvertido actualmente. Nuestro objetivo es describir y analizar los resultados del ReTC en Espana. Metodos Analisis retrospectivo del Registro Espanol de Trasplante Cardiaco de 1984 a 2018. Se recogieron datos sobre donante, receptor, cirugia, inmunosupresion y supervivencia. La mortalidad por todas las causas o la necesidad de ReTC postrasplante fueron el objetivo principal. Se estudiaron diferencias en supervivencia segun indicacion, tiempo entre trasplantes y epoca del ReTC. Resultados Se estudiaron en total 7.592 trasplantes cardiacos (TxC) y 173 (2,3%) ReTC (mediana de edad, 52,0 y 55,0 anos respectivamente). La enfermedad vascular del injerto fue la indicacion de ReTC mas frecuente (42,2%) y 59 pacientes (80,8%) recibieron el ReTC mas de 5 anos despues del trasplante inicial. El rechazo agudo y el fallo primario del injerto disminuyeron como indicaciones durante el periodo estudiado.

Hay una tendencia a realizar menos trasplantes urgentes, la mayoria con dispositivos de asistencia ventricular.

Introduction:Heart transplant after Fontan completion poses a unique surgical challenge. Twenty patients are presented, stressing the technical hints performed in the five anastomoses to match the graft in the recipient.Methods:Data are collected from 20 Fontan patients between 2013 and 2019. Age (13 years), weight (37 kg.), and time interval between Fontan and transplant (7 years) are presented as median. Extracardiac conduit (size 18/20) was implanted in 15 patients, whereas atrio-pulmonary connection was performed in 4 and lateral tunnel in 1. Six patients developed protein-losing enteropathy. Seventeen stents had been previously deployed.Results:The five anastomoses underwent some changes. Left atrium once, aorta 9 times, superior vena cava 7 times, pulmonary branches 15 times, and inferior vena cava 12 times. Follow-up was complete for a median of 42 months (range 6–84). Two patients died. ECMO was needed in six cases for pulmonary hypertension. Four patients had collateral vessels occluded in the cath lab, and stents were placed in superior vena cava (1) and aorta (1) post-transplant. Protein-losing enteropathy was resolved in five patients. Interestingly, one patient was on a systemic assist device before transplant (Levitronix) and right assistance (ECMO) afterwards.Conclusions:Transplant in Fontan patients is actually challenging. Hints in every of the five proposed anastomoses must be anticipated, including stents removal. Extra tissue from the donor (innominate vein, aortic arch, and pericardium) is strongly advisable. ECMO for right ventricular dysfunction was needed in nearly one-third of the cases. Overall results can match other transplant cohorts.

Introduction and objectives: The present report describes the clinical characteristics and outcomes of heart transplants in Spain and updates the data to 2019. Methods: We describe the clinical characteristics and outcomes of heart transplants performed in Spain in 2019, as well as trends in this procedure from 2010 to 2018. Results: In 2019, 300 transplants were performed (8794 since 1984; 2745 between 2010 and 2019). Compared with previous years, the most notable findings were the decreasing rate of urgent transplants (38%), and the consolidation of the type of circulatory support prior to transplant, with an almost complete disappearance of counterpulsation balloon (0.7%), stabilization in the use of extracorporeal membrane oxygenation (9.6%), and an increase in the use of ventricular assist devices (29.0%). Survival from 2016 to 2018 was similar to that from 2013 to 2015 (P = .34). Survival in both these periods was better than that from 2010 to 2012 (P = .002 and P = .01, respectively). Conclusions: Heart transplant activity has remained stable during the last few years, as have outcomes (in terms of survival). There has been a trend to a lower rate of urgent transplants and to a higher use of ventricular assist devices prior to transplant.

Heart retransplantation (ReHT) is controversial in the current era. The aim of this study was to describe and analyze the results of ReHT in Spain. Methods We performed a retrospective cohort analysis from the Spanish Heart Transplant Registry from 1984 to 2018. Data were collected on donors, recipients, surgical procedure characteristics, immunosuppression, and survival. The main outcome was posttransplant all-cause mortality or need for ReHT. We studied differences in survival according to indication for ReHT, the time interval between transplants and era of ReHT. Results A total of 7592 heart transplants (HT) and 173 (2.3%) ReHT were studied (median age, 52.0 and 55.0 years, respectively). Cardiac allograft vasculopathy was the most frequent indication for ReHT (42.2%) and 59 patients (80.8%) received ReHT > 5 years after the initial transplant. Acute rejection and primary graft failure decreased as indications over the study period. Renal dysfunction, hypertension, need for mechanical ventilation or intra-aortic balloon pump and longer cold ischemia time were more frequent in ReHT. Median follow-up for ReHT was 5.8 years. ReHT had worse survival than HT (weighted HR, 1.43; 95%CI, 1.17-1.44; P < .001). The indication of acute rejection (HR, 2.49; 95%CI, 1.45-4.27; P < .001) was related to the worst outcome. ReHT beyond 5 years after initial HT portended similar results as primary HT (weighted HR, 1.14; 95%CI, 0.86-1.50; P < .001). Conclusions ReHT was associated with higher mortality than HT, especially when indicated for acute rejection. ReHT beyond 5 years had a similar prognosis to primary HT.

INTRODUCTION AND OBJECTIVES The present report updates the characteristics and results of heart transplantation in Spain, mainly focused in the 2008-2017 period. METHODS We describe the recipient and donor characteristics, surgical procedures, and outcomes of heart transplants performed in 2017. The 2017 data were compared with those obtained from 2008 to 2016. RESULTS A total of 304 cardiac transplants were performed in 2017. Between 1984 and 2017, 8173 procedures were performed, 2689 of them after 2008. Significant temporal trends were observed in recipient characteristics (lower pulmonary vascular resistance, lower use of mechanical ventilation, and a higher percentage of diabetic patients and those with previous cardiac surgery), donor characteristics (older donor age and a higher percentage of female donors and those with a prior cardiac arrest) and procedures (lower ischemia time). In 2017, 27% of patients were transplanted after undergoing mechanical ventricular assistance (P

Arterial ischemic strokes (AIS) are rare in childhood. Congenital and acquired heart diseases are one of the most important risk factors of AIS in children. Objective Study the outcome of children with heart disease that have suffered AIS and the factors that influence on prognosis. Patients and Methods We evaluated all children with heart disease who had suffered AIS between 2000 and 2014 in our hospital. Results Seventy-four children with heart disease suffered an arterial ischemic stroke. 20% of them died and 10% had new AIS during the study period. Fifty-two patients were evaluated an average of six years after AIS. According to the Paediatric Stroke Outcome Scale (PSOM), most of the patients had some degree of impairment, mainly in sensorimotor and in cognitive-behavioural areas. The modified Rankin scale (mRS) showed an unfavourable outcome in 70% of patients (including patients that have died). Upper limb was more functionally impaired than lower limb. Strokes in neonatal period and early life were associated with poor prognosis. Size of stroke, cortical and subcortical involvement and basal ganglia stroke were associated with an unfavourable outcome. Fever in the acute phase and hemiparesis at presentation were also poor prognostic factors. Epilepsy at time of evaluation was also associated with unfavourable outcome. On the other hand, a normal electroencephalogram was associated with favourable outcome. Conclusions AIS in children with heart disease had an unfavourable outcome, with impairment in different areas. Epilepsy happened in one third of the patients.

Introducción y objetivos: El trasplante cardíaco pediátrico constituye un reto multidisciplinar y son escasas las series amplias a nivel mundial. Presentamos evolución, tendencias y resultados de nuestra serie y perspectivas futuras. Material y métodos: Desde inicio del programa (1990) hasta 2015, se han realizado 163 trasplantes (158 pacientes): 50,3% (n = 82) cardiopatías congénitas (80,5% [n = 66] univentriculares); 33,7% (n = 55) miocardiopatía dilatada; 4,3% (n = 7) miocardiopatía hipertrófica; 3,6% (n = 5) retrasplante, y 7,9% (n = 14) otras causas. La edad media fue 5,1 ± 3,2 años (rango 11 días-17 años) y peso medio 17,2 ± 3 kg (rango 2,8-70). Se realizaron análisis descriptivo, comparativo (períodos históricos) y análisis multivariante y de seguimiento (Software-R-Core-Team-2013). Resultados: A partir del 2003, se incrementa el número global de trasplantes cardíacos, convirtiéndose la fisiología univentricular en estadio Glenn (n = 14) y Fontan (n = 10) la cardiopatía congénita más prevalente, precisando reconstrucciones complejas preimplante. La mortalidad global a 30 días fue del 20,2% (n = 33), descendiendo en el segundo período (14,4% vs. 30,5%, p

WBS is a rare disorder caused by mutations in the chromosomal sub-band 7q11.23 involving the elastin gene. The clinical features (craniofacial, developmental, and cardiovascular abnormalities) are variable. The association with cardiac anomalies is a well-recognized feature, and SVAS is the most common cardiac defect found. End-stage ischemic heart disease is unusual in this setting but when it occurs, OHT remains the final therapeutic option. This decision can be difficult to determine, and it must be tailored to the individual patient based on the clinical status and concomitant cardiovascular and multisystem lesions. To date, no cases of OHT in patients with WBS have been described. We present a 14-month-old patient with WBS who developed severe LV dysfunction secondary to ischemia following a complex staged surgery for SVAS repair. He underwent successful OHT with no post-operative complications, and at three-month follow-up, he remains asymptomatic on standard immunosuppressive therapy. This case constitutes the first demonstration that OHT may be indicated for extended survival in selected children with WBS and we discuss the basic principles for extending the indication for OHT to this scenario as well as the particularities for post-transplant care.

Acute renal injury increases risk of death after cardiac surgery. The objective of the study was to evaluate the ability of the pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease (pRIFLE) criteria to characterize the development of postoperative renal damage in children after cardiopulmonary bypass (CPB) and to evaluate the relationship between the severity of kidney injury and mortality, pediatric intensive care unit (PICU) length of stay, and the duration of mechanical ventilation (MV).In this retrospective study including children undergoing CPB surgery during a 3-year period in the PICU of a tertiary hospital, demographic, clinical, surgery-related, and postoperative clinical data were collected. Kidney damage was assessed with pRIFLE criteria.Four hundred and nine patients were included. Early acute kidney injury (AKI) was found in 82 patients (achieving categories Risk 44; Injury 16; Failure 22). Early AKI was associated with younger age (P = 0.010), longer CPB, deep hypothermic circulatory arrest (DHCA) use, ICU stay12 days, MV4 days, and death (P 0.001). Controlling the effect of age, CPB, DHCA use, previous cardiac surgeries, and Risk Adjustment in Congenital Heart Surgery Surgical Severity Score (RACHS-1), early AKI development proved to predict ICU stay12 days [odds ratio (OR) 3.5; 95% confidence interval (CI) 1.9-6.5, P 0.001)] and need of MV4 days (OR 5.1; 95% CI 2.6-10.2, P 0.001).Early AKI when evaluated with the pRIFLE criteria can predict prolonged ICU stay, need of prolonged MV, and mortality.

Orthotopic heart transplantation after univentricular palliation presents a difficult challenge due to the complex anatomy and prior surgeries.

ResumenIntroducción y objetivosEl trasplante cardiaco tras un Fontan supone un reto quirúrgico. Presentamos a 10 pacientes, destacando las variantes técnicas en las anastomosis previas a la implantación del injerto.MétodosRecogemos 8 casos de Fontan y 2 «take-down» consecutivos durante 32 meses, con medianas de edad (9 años), peso (30 kg) e intervalo entre Fontan y trasplante de 3 años. Siete pacientes presentaban conducto extracardiaco (diámetro 18/20), 2 conexión aurículo-pulmonar y uno, túnel lateral. Tres niños desarrollaron enteropatía pierde-proteínas. Nueve «stents» fueron implantados previamente.ResultadosHubo modificaciones en las 5 anastomosis. Una vez en la aurícula izquierda (sutura en ambas aurículas del receptor), 2 en la aorta (hemiarco), 2 en vena cava superior (plastia en vena innominada), 7 veces en la arteria pulmonar (parche de aorta/pericardio donante de hilio a hilio tras retirada de «stents»), vena cava inferior en 7 ocasiones (manguito de conducto). El seguimiento fue completo con una mediana de 25 meses (rango 3-34). Un paciente falleció. Dos precisaron extracorporeal membrane oxygenation por hipertensión pulmonar. Tres pacientes requirieron cierre de colaterales en hemodinámica, incluyendo colocación de «stent» en cava superior (1) y aorta (1). Se resolvió la enteropatía pierde-proteínas en 2 pacientes.ConclusionesTrasplantar a pacientes con Fontan previo es un reto. Podemos anticipar variantes en cada una de las 5 anastomosis previstas. Es recomendable obtener tejido extra del donante (aorta y arco, vena cava superior e innominada, pericardio). Los resultados pueden superponerse a otras series de trasplante cardiaco.AbstractIntrodcution and objectivesHeart transplantation after a Fontan procedure poses a unique challenge from a surgical point of view. The cases of ten patients are presented, stressing the technical variations performed in the five anastomoses in order to match the graft in the recipient.MethodsEight Fontan and two takedown patients were included over 32 consecutive months. The median age was 9 years, median weight was 30 Kg, with a median time interval of 3 years between Fontan and transplant. An extra-cardiac conduit (size 18/20) was implanted in seven patients, whereas an atriopulmonary connection was found in two, and lateral tunnel in one. Three patients developed protein-losing enteropathy. Nine stents were previously implanted.ResultsThe five anastomoses underwent some changes. Left atrium once (enlargement with recipient both atria), aorta twice (hemi-arch repair), superior vena cava twice (innominate donor plasty), pulmonary branches seven times (hilum to hilum plasty with donor aorta/pericardium patch after complete stent removal), and inferior vena cava seven times (conduit sleeve anastomoses). The patients were followed-up for a median of 25 months (range 5-34). One patient died. Extracorporeal membrane oxygenation was needed in two cases due to pulmonary hypertension. Three patients had collateral vessels occluded in the catheter laboratory, and stents placed in superior vena cava (1) and aorta (1). The protein-losing enteropathy was resolved in two children.ConclusionsTransplant in Fontan patients is currently challenging. Variations in each of the five proposed anastomoses must be anticipated. Extra tissue from the donor (innominate vein, aortic arch, pericardium) is strongly advisable. Overall results can match other transplants cohorts.
