Nutrition in congenital heart disease: consensus document.

INTRODUCTION: The prevalence of malnutrition among infants with congenital heart disease (CHD) is high. 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.

La nutrición en las cardiopatías congénitas: Documento de consenso / Nutrition in congenital heart disease: Consensus document

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. Con base en la literatura y en 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 dos 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 cardiacos o extracardiacos 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.

Results of heart retransplantation: subanalysis of the Spanish Heart Transplant Registry.

INTRODUCTION AND OBJECTIVES: 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.

Multi-inflammatory Syndrome in Children Related to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Spain.

Some clusters of children with a multisystem inflammatory syndrome (MIS-C) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported. We describe the epidemiological and clinical features of children with MIS-C in Spain. MIS-C is a potentially severe condition that presents in children with recent SARS-CoV-2 infection.

Technical modifications for transplant in the failing Fontan.

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.

Outcome of arterial ischemic stroke in children with heart disease.

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.

End-stage ischemic heart failure and Williams-Beuren syndrome: A unique scenario for pediatric heart transplantation.

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.

Prognostic relevance of early AKI according to pRIFLE criteria in children undergoing cardiac surgery.

BACKGROUND: 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). METHODS: 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. RESULTS: 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 stay >12 days, MV >4 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 stay >12 days [odds ratio (OR) 3.5; 95% confidence interval (CI) 1.9-6.5, P < 0.001)] and need of MV >4 days (OR 5.1; 95% CI 2.6-10.2, P < 0.001). CONCLUSIONS: Early AKI when evaluated with the pRIFLE criteria can predict prolonged ICU stay, need of prolonged MV, and mortality.
