Brain anatomopathological findings in neonates with congenital heart disease.

INTRODUCTION: Neonates with congenital heart disease can develop neurological problems, which is why it is important to know the time and extent at which these lesions occur in order to elucidate their causes and implications. OBJECTIVE: To describe brain morphological alterations in autopsies of neonates with congenital heart disease. METHODS: The cases of neonates with congenital heart disease and complete autopsy registered in the pathology department from 2009 to 2019 were included. Descriptive statistics were used with the calculation of frequencies and percentages. RESULTS: Of a total of 21 patients, 61.9% were full-term males; median weight and age at admission were 2500 g and five days, respectively; mean hospital stay was seven days. The predominant heart disease was aortic arch pathology. Fifteen patients (71.3%) underwent surgery; 50% died of cardiogenic shock, 100% had hypoxic-ischemic brain lesions, 71% had incipient lesions, and 33.3%, parenchymal hemorrhage. CONCLUSIONS: There are various risk factors for neurological damage in patients with complex congenital heart disease, which is impossible to be entirely controlled. This study allows us to know, for the first time in our milieu, the changes in the central nervous system that could exist in these patients.

INTRODUCCIÓN: Los neonatos con cardiopatía congénita pueden desarrollar problemas neurológicos, por lo que es importante conocer el momento en el que ocurren dichas lesiones y su extensión, para dilucidar sus causas e implicaciones. OBJETIVO: Describir las alteraciones morfológicas cerebrales en autopsias de neonatos con cardiopatía congénita. MÉTODOS: Se incluyeron los casos de neonatos con cardiopatía congénita y autopsia completa registrados en un servicio de patología, de 2009 a 2019.

La cardiopatía predominante fue la patología de arco aórtico. Quince pacientes (71.3 %) fueron sometidos a cirugía; 50 % falleció por choque cardiogénico, 100 % presentó lesiones hipóxico-isquémicas cerebrales; 71 %, lesiones incipientes; 33.3 %, hemorragia parenquimatosa. CONCLUSIONES: Existen diversos factores de riesgo para daño neurológico en los pacientes con cardiopatía congénita compleja, los cuales es imposible controlar en su totalidad. Este estudio permite conocer, por primera vez en nuestro medio, los cambios en el sistema nervioso central que podrían existir en estos pacientes.

Neurological repercussions of changes in cerebral blood flow in neonates undergoing cardiovascular surgery.

INTRODUCTION: Surgery for congenital heart disease can generate cerebral perfusion-associated alterations with neurological repercussions. OBJECTIVE: To analyze the relationship of peri-surgical cerebrovascular resistance index (RI) with mediate neurological functions after congenital heart disease surgery. METHOD: Prospective cohort study of 34 neonates in whom basilar artery RI, serum oxygen, carbon dioxide and lactate levels were determined before and after palliative or corrective procedures. We related pre-surgical RI with post-surgical ability to initiate the enteral route or to restore unassisted spontaneous breathing. RESULTS: Three groups were formed: 79 neonates with high RI (> 0.73), 73 with normal RI (0.63 to 0.73) and eight with low RI (< 0.63). In the former group, high RI persisted in the postoperative period, with persistent hyperlactatemia and hypoxia; in 86 %, the enteral route could not be initiated, and neither could assisted ventilation be withdrawn. In the second group, RI remained within normal values. In the third group, although RI, serum lactate and arterial oxygen pressure tended to normalize, 71 % had severe neurological damage. CONCLUSIONS: RI changes were common, although neurological damage appears to occur more commonly when RI remains high, possibly associated with low cerebral blood flow.

INTRODUCCIÓN: La cirugía de cardiopatías congénitas puede generar alteraciones perfusorias cerebrales con repercusión neurológica. OBJETIVO: Analizar la relación del índice de resistencia (IR) vascular cerebral periquirúrgico con funciones neurológicas mediatas posteriores a cirugía de cardiopatía congénita. MÉTODO: Estudio de cohorte prospectivo de 34 neonatos en quienes se determinó IR de la arteria basilar, niveles séricos de oxígeno, dióxido de carbono y lactato, antes y después de procedimientos paliativos o correctivos. Relacionamos el IR prequirúrgico con la capacidad posquirúrgica para iniciar la vía enteral o restablecer la respiración espontánea no asistida. RESULTADOS: Se integraron tres grupos: 79 neonatos con IR alto > 0.73, 73 con IR normal de 0.63 a 0.73 y ocho con IR bajo < 0.63. En los primeros persistió IR elevado en el posquirúrgico, con hiperlactatemia e hipoxia persistentes; en 86 % no se logró iniciar la vía enteral ni retirar la ventilación asistida. En los segundos, el IR se mantuvo en valores normales. En los terceros, si bien el IR, el lactato sérico y la presión arterial de oxígeno tendieron a normalizarse, 71 % presentó daño neurológico grave. CONCLUSIONES: Los cambios en el IR fueron frecuentes, aunque el daño neurológico parece presentarse más cuando el IR se mantiene alto, posiblemente asociado con flujos cerebrales bajos.

Ischaemic stroke in children with cardiopathy: An epidemiological study. / Ictus isquémico en niños con cardiopatía: estudio epidemiológico.

INTRODUCTION: Ischaemic stroke is rare during childhood. Congenital and acquired heart diseases are one of the most important risk factors for arterial ischaemic stroke (AIS) in children. PATIENTS AND METHODS: We conducted a retrospective study of all children with AIS and heart disease diagnosed between 2000 and 2014. RESULTS: We included 74 children with heart disease who were eligible for inclusion. 60% were boys with a mean stroke age of 11 months. 20% of the patients died during the study period. 90% of the patients had a congenital heart disease, while cyanotic heart disease was identified in 60%. Hypoplastic left heart syndrome was the most frequent heart disease. In 70% of patients AIS was directly associated with heart surgery, catheterisation or ventricular assist devices. Most patients with AIS were in the hospital. Seizures and motor deficit were the most frequent symptoms. Most patient diagnoses were confirmed by brain CT. The AIS consisted of multiple infarcts in 33% of the cases, affected both hemispheres in 27%, and involved the anterior and posterior cerebral circulation in 10%. CONCLUSIONS: Arterial ischaemic strokes were mainly associated with complex congenital heart diseases, and heart procedures and surgery (catheterisation). AIS presented when patients were in-hospital and most of the patients were diagnosed in the first 24hours.

[Hospital morbidity and mortality in children with Down's syndrome: Experience in a university hospital in Chile]. / Morbimortalidad hospitalaria en niños con síndrome de Down.

INTRODUCTION: Children with Down's syndrome (DS) have a higher risk of congenital malformations and acute diseases, with increased risk of hospital admissions compared with the general population. This study describes patterns of hospital admissions for children and adolescents with DS. PATIENTS AND METHODS: A retrospective study of hospital admissions of children with DS, younger than 15 years old, and cared for by the Paediatric Department of the Hospital Clínico Pontificia Universidad Católica de Chile, between 2008 and 2011. RESULTS: There were 222 admissions of 161 patients with DS during the study period, of which 110 were girls. The median age was 8 months, and the median hospital stay was 6 days. Just over half (56.7%) of the hospital stays were in the Paediatric Critic Care Unit. Heart surgery was performed on 59.4%, and the principal congenital heart defect attended was atrioventricular canal. The principal diagnosis, other than heart surgery, was lower respiratory tract infection. In this series, 3 children died. CONCLUSIONS: Children with DS are a relevant group for inpatient care, because their high incidence in Chile, their respiratory and cardiovascular risk, prolonged hospitalizations, high frequency of critical care days and mortality risk. This group has special and complex needs during their hospitalizations and it is necessary to create a multidisciplinary team with competences to take care the particular characteristics of this vulnerable group.

Magnetic resonance imaging in the assessment of anomalous pulmonary venous connections.

OBJECTIVE: To illustrate the morphological and functional magnetic resonance findings for total and partial anomalous pulmonary venous connections as well as of the most common complications after surgery. CONCLUSION: The magnetic resonance findings are fundamental in defining the type of anomalous connection, deciding on the treatment, planning the surgery, and detecting postsurgical complications.

Neurodevelopmental outcomes in congenital heart disease: Usefulness of biomarkers of brain injury.

INTRODUCTION: At present, neurodevelopmental abnormalities are the most frequent type of complication in school-aged children with congenital heart disease (CHD). We analysed the incidence of acute neurologic events (ANEs) in patients with operated CHD and the usefulness of neuromarkers for the prediction of neurodevelopment outcomes. METHODS: Prospective observational study in infants with a prenatal diagnosis of CHD who underwent cardiac surgery in the first year of life. We assessed the following variables: (1) serum biomarkers of brain injury (S100B, neuron-specific enolase) in cord blood and preoperative blood samples; (2) clinical and laboratory data from the immediate postnatal and perioperative periods; (3) treatments and complications; (4) neurodevelopment (Bayley-III scale) at age 2 years. RESULTS: the study included 84 infants with a prenatal diagnosis of CHD who underwent cardiac surgery in the first year of life. Seventeen had univentricular heart, 20 left ventricular outflow obstruction and 10 genetic syndromes. The postoperative mortality was 5.9% (5/84) and 10.7% (9/84) patients experienced ANEs. The mean overall Bayley-III scores were within the normal range, but 31% of patients had abnormal scores in the cognitive, motor or language domains. Patients with genetic syndromes, ANEs and univentricular heart had poorer neurodevelopmental outcomes. Elevation of S100B in the immediate postoperative period was associated with poorer scores. CONCLUSIONS: children with a history of cardiac surgery for CHD in the first year of life are at risk of adverse neurodevelopmental outcomes. Patients with genetic syndromes, ANEs or univentricular heart had poorer outcomes. Postoperative ANEs may contribute to poorer outcomes. Elevation of S100B levels in the postoperative period was associated with poorer neurodevelopmental outcomes at 2 years. Studies with larger samples and longer follow-ups are needed to define the role of these biomarkers of brain injury in the prediction of neurodevelopmental outcomes in patients who undergo surgery for management of CHD.

Adverse cardiovascular, obstetric and perinatal events during pregnancy and puerperium in patients with heart disease.

BACKGROUND AND OBJECTIVES: cardiovascular changes during pregnancy carry greater risk in heart disease. We analyze cardiovascular, obstetric and perinatal adverse effects associated with congenital and acquired heart disease during pregnancy and postpartum. MATERIALS AND METHODS: Cross-sectional and retrospective study, which included the 2017-2023 registry of pregnant or postpartum patients hospitalised with diagnosis of congenital or acquired heart disease. Adverse events (heart failure, stroke, acute pulmonary edema, maternal death, obstetric haemorrhage, prematurity and perinatal death) were compared with the clinical variables and the implemented treatment. RESULTS: 112 patients with a median age of 28 years (range 15-44) were included. Short circuits predominated 28 (25%). Thirty-six patients (32%) were classified in class IV of the modified WHO scale for maternal cardiovascular risk. Heart failure occurred in 39 (34.8%), acute lung edema 12 (10.7%), stroke 2 (1.8%), maternal death 5 (4.5%), obstetric haemorrhage 4 (3.6%), prematurity 50 (44.5%) and perinatal death 6 (5.4%). Shunts were associated with prematurity (adjusted odds ratio 4; 95% CI: 1.5-10, p = 0.006). Peripartum cardiomyopathy represented higher risk of pulmonary edema (adjusted OR 34; 95% CI: 6-194, p = 0.001) and heart failure (adjusted OR 16; 95% CI: 3-84, p = 0.001). An increased risk of obstetric haemorrhage was observed in patients with prosthetic valves (adjusted OR 30; 95% CI: 1.5-616, p = 0.025) and with the use of acetylsalicylic acid (adjusted OR 14; 95% CI: 1.2-16, p = 0.030). Furthermore, the latter was associated with perinatal death (adjusted OR 9; 95% CI: 1.4-68, p = 0.021). CONCLUSIONS: severe complications were found during pregnancy and postpartum in patients with heart disease, which is why preconception evaluation and close surveillance are vital.

[Validation of the instrument "Infant Malnutrition and Feeding Checklist for Congenital Heart Disease", a tool to identify risk of malnutrition and feeding difficulties in infants with congenital heart disease]. / Validación del instrumento Infant Malnutrition and Feeding Checklist for Congenital Heart Disease, una herramienta para identificar riesgo de desnutrición y dificultades de alimentación en lactantes con cardiopatías congénitas.

Introduction: Introduction: currently, various tools have been designed to timely detect the risk of malnutrition in hospitalized children. In those with a diagnosis of congenital heart disease (CHD), there is only one tool developed in Canada: Infant Malnutrition and Feeding Checklist for Congenital Heart Disease (IMFC:CHD), which was designed in English. Objective: to evaluate the validity and reliability of the Spanish adaptation of the IMFC:CHD tool in infants with CHD. Methods: cross-sectional validation study carried out in two stages. The first, of translation and cross-cultural adaptation of the tool, and the second, of validation of the new translated tool, where evidence of reliability and validity were obtained. Results: in the first stage, the tool was translated and adapted to the Spanish language; for the second stage, 24 infants diagnosed with CHD were included. The concurrent criterion validity between the screening tool and the anthropometric evaluation was evaluated, obtaining a substantial agreement (κ = 0.660, 95 % CI: 0.36-0.95) and for the predictive criterion validity, which was compared with the days of hospital stay, moderate agreement was obtained (κ = 0.489, 95 % CI: 0.1-0.8). The reliability of the tool was evaluated through external consistency, measuring the inter-observer agreement, obtaining a substantial agreement (κ = 0.789, 95 % CI: 0.5-0.9), and the reproducibility of the tool showed an almost perfect agreement (κ = 1, CI 95 %: 0.9-1.0). Conclusions: the IMFC:CHD tool showed adequate validity and reliability, and could be considered as a useful resource for the identification of severe malnutrition.

Introducción: Introducción: actualmente, se han diseñado diversas herramientas para detectar oportunamente el riesgo de desnutrición en niños hospitalizados. En aquellos con diagnóstico de cardiopatías congénitas (CC), solo existe una herramienta desarrollada en Canadá, llamada Infant Malnutrition and Feeding Checklist for Congenital Heart Disease (IMFC:CHD), la cual fue diseñada en idioma inglés. Objetivo: evaluar la validez y confiabilidad de la adaptación en español de la herramienta IMFC:CHD en lactantes con CC. Métodos: estudio transversal de validación realizado en dos etapas: la primera, de traducción y adaptación transcultural de la herramienta; y la segunda, de validación de la nueva herramienta traducida, donde se obtuvieron las evidencias de confiabilidad y validez. Resultados: en la primera etapa se obtuvo la herramienta traducida y adaptada al idioma español; para la segunda etapa se incluyeron 24 lactantes con diagnóstico de CC. Se evaluó la validez de criterio concurrente entre la herramienta de tamizaje y la evaluación antropométrica, obteniéndose un acuerdo sustancial (κ = 0,660, IC 95 %: 0,36-0,95). Para la validez de criterio predictiva, la cual fue comparada con los días de estancia hospitalaria, se obtuvo un acuerdo moderado (κ = 0,489, IC 95 %: 0,1-0,8). La confiabilidad de la herramienta se evaluó mediante consistencia externa, midiendo la concordancia interobservador, y se obtuvo un acuerdo sustancial (κ = 0,789, IC 95 %: 0,5-0,9); la reproducibilidad de la herramienta mostró un acuerdo casi perfecto (κ = 1, IC 95 %: 0,9-1,0). Conclusiones: la herramienta IMFC:CHD mostró una adecuada validez y confiabilidad, por lo que podría considerarse un recurso útil para la identificación de desnutrición grave.

Congenital heart defects and preterm birth: Outcomes from a referral center.

BACKGROUND: Preterm birth and congenital heart defects are two major causes of neonatal and infant mortality. However, the relationship between them has not yet been fully clarified. OBJECTIVE: To determine the prevalence and spectrum of congenital heart defects in preterms, the specific associations between categories of congenital heart defects and preterm birth and to establish the influence on outcomes. METHODS: Observational, case-control analysis that included 448 live births with congenital heart defects born between 2003 and 2017. Preterm with congenital heart defects were the case subjects and term neonates with congenital heart defects the control subjects. RESULTS: Of the newborns with congenital heart defects, 23% were preterm. The odds of congenital heart defects in preterm were twofold higher than for term neonates (p<0.0001), even when considering only those with severe congenital heart defects (p=0.0002). The odds in preterm were 9.2-fold higher for abnormalities of the atria and atrial septum (p<0.0001) and two-fold higher for abnormalities of the ventricles and ventricular septum (p<0.0001) compared with term neonates. The neonatal mortality rate in the preterm group was not statistically different from that of the term group with congenital heart defects (p=0.799) or severe congenital heart defects (p=0.554). CONCLUSION: Preterm have more than twice as many congenital heart defects as term neonates. Although the etiology of prematurity between infants with congenital heart defects is still uncertain, our findings highlight a possible relationship between prematurity and congenital heart defects.

Does transcatheter ventricular septal defect closure affect heart rate variability in children?

BACKGROUND: Heart rate variability (HRV) is a sign of the cardiac autonomic nervous system. Its evaluation in pediatric ventricular septal defect (VSD) cases before and after transcatheter closure contributes to an understanding of cardiac autonomic control. METHODS: Nineteen children with VSDs treated with transcatheter closure and 18 healthy children were enrolled in this study. A 24-h Holter rhythm monitor was applied to all patients before VSD closure and to those in the control group. Holter rhythm monitoring was repeated at three months in the patient group. HRV parameters were measured using the Cardio Scan Premier 12® program. Frequency-domain (total power; very-low-frequency, low-frequency (LF), and high-frequency (HF) indices; and the LF/HF ratio) and time-domain (standard deviation of all RR intervals (SDNN), standard deviation of 5-min averages of RR intervals (SDANN), the SDNN index, percentage of the difference between adjacent RR intervals, and the square root of the mean of the sum of square differences between adjacent filtered RR intervals) parameters were assessed. RESULTS: Before the procedure, SDNN, SDANN, and total power values were lower in the patient group than in the control group; other parameters were similar in the two groups. No significant difference in the SDNN, SDANN, or total power was detected between the patient and control groups in the third month, indicating that autonomic control of patients' hearts became normal during the third postoperative month. No correlation was detected between any hemodynamic parameters and any time-domain or frequency-domain parameters before closure. CONCLUSION: This study showed that transcatheter closure of VSDs changed HRV parameters in pediatric patients.

First record of pediatric cardiovascular interventional procedures performed in a state pediatric catheterization laboratory in El Salvador.

OBJECTIVE: To describe the types of cardiac catheterization that are performed in the only pediatric catheterization laboratory within the public health network of El Salvador, in collaboration with non-profit organizations. MATERIAL AND METHOD: A descriptive, retrospective, cross-sectional study was conducted in the period from May 2022 to January 2023, reviewing the records of all patients who underwent cardiac catheterization. RESULTS: 54 procedures were performed in the catheterization room, 37 female patients. The weight was 20.6 ± 14.5 kg, of the procedures, 47 (87%) were therapeutic and 7 (13%) diagnostic. Occlusion of the ductus arteriosus was performed in 46% of the patients. No complications were reported, the patients were discharged after 12 hours, all supplies were donated by non-profit foundations. CONCLUSIONS: Our catheterization laboratory performs procedures of varied complexity without reporting any major complications to date. We are limited due to the high cost of some devices, the low frequency of their use and the impossibility of acquiring them in the national market.

OBJETIVO: Describir los tipos de cateterismo cardiaco que se realizan en el único laboratorio de hemodinamia pediátrica dentro de la red de salud pública de El Salvador, en colaboración con organizaciones sin fines de lucro. MATERIAL Y MÉTODO: Se realizó un estudio descriptivo retrospectivo de corte transversal en el periodo entre mayo de 2022 a enero de 2023, revisando los expedientes de todos los pacientes que pasaron a cateterismo cardiaco. RESULTADOS: Se realizaron 54 procedimientos dentro de la sala de hemodinamia, 37 pacientes de sexo femenino. El peso fue de 20.6 ± 14.5 kg, de los procedimientos, 47 (87%) fueron terapéuticos y 7 (13%) diagnósticos. La oclusión del conducto arterioso se realizó en el 46% de los pacientes. No se reportaron complicaciones, los pacientes fueron dados de alta luego de 12 horas, todos los insumos fueron donados por fundaciones sin fines de lucro. CONCLUSIONES: Nuestro laboratorio de hemodinamia realiza procedimientos de complejidad variada sin reportar hasta el momento complicaciones mayores. Nos vemos limitados debido al costo alto de algunos dispositivos, a la baja frecuencia de la utilización de estos y a la imposibilidad para adquirirlos en el mercado nacional.

Nursing care in the postoperative period after Glenn surgery. A case report.

Glenn surgery is used as a palliative procedure in children with Hypoplastic Left Heart Syndrome (HLHS) and its objective is to partially redirect the systemic venous return. An individualized care plan is presented for a 7-month-old infant, admitted to the Pediatric Intensive Care Unit (PICU), after undergoing Glenn procedure. And is shown her evolution during admission. Marjorie Gordon's 11 functional health patterns are used for the nursing assessment, highlighting among the altered patterns, the nutritional-metabolic and the activity-exercise, due to their implication in hemodynamic changes derived from the surgery. Due to their association with the most common postoperative complications in this type of surgery, 8 diagnoses were prioritised according to NANDA-I taxonomy: risk for infection, excess fluid volume, risk for shock, risk for bleeding, risk for decreased cardiac output, impaired gas exchange, ineffective airway clearance and risk for ineffective cerebral tissue perfusion. In each of them, expected patient outcomes and nursing interventions, were selected using the NOC and NIC taxonomies, respectively. Outcome criteria scores showed a favourable evolution after 7 days from admission, only 3 of the diagnoses selected at the beginning remain active. The development and reassessment of the nursing care plan has made it possible to make an effective monitoring of patient's postoperative evolution and to standardize nursing care, ensuring safe and quality health care. The lack of similar case reports in available bibliography has prevented us from comparing actions, therefore it has been necessary to disclose these scientific articles to guarantee best evidence-based practice.

Influence of contrast enhancement at the contrast injection location for the arm or leg in neonatal and infant patients during cardiac computed tomography.

INTRODUCTION AND OBJECTIVES: Obtaining CCTA images with optimal injection location such as the arm or leg is important to avoid the artifacts caused by the CM. This study compares the computed tomography (CT) numbers and visualization scores of the three-dimensional (3D) images of the lumens of the blood vessels in the arm or leg during cardiac computed tomography angiography (CCTA) in neonatal and infant patients. PATIENTS OR MATERIALS AND METHODS: Between January 2017 and January 2020, 253 consecutive patients were considered for inclusion. We used the estimated propensity scores as a function of the demographic data, including age, body weight, and injection location (right or left side) in the arm (n = 58) and leg (n = 58) of neonatal and infant patients. We compared the mean CT numbers of the pulmonary artery, ascending aorta, and left superior vena cava; contrast-noise ratios (CNR); and visualization scores between the arm and leg as the injection locations. RESULTS: The mean CT numbers during CCTA for the arm and leg were 479.4 and 461.3 HU in the ascending aorta, 464.2 and 448.1 HU in the pulmonary artery, and 232.8 and 220.1 HU in the left superior vena cava, respectively. The mean image noise (SD) and CNR values, respectively, were 38.9 HU and 12.1 for the arm as the injection location and 39.1 HU and 12.3 for the leg as the injection location. The median visualization scores of volume rendering of the 3D images were 3.0 and 3.0 for the arm and leg injection sites, respectively. There were no significant differences in the mean CT numbers of the ascending aorta, pulmonary artery, and left superior vena cava; SD value; CNR; and visualization scores between the arm and leg injection locations. CONCLUSIONS: The CT numbers of the lumen of the blood vessel and visualization scores of the 3D images of the arm and leg injection locations are equal during CCTA in neonatal and infant patients with congenital heart disease.

[Psychocardiological intervention in the cardiovascular rehabilitation of school children with congenital heart disease: A systematic review]. / La intervención psicocardiológica en la rehabilitación cardiovascular de niños escolares con cardiopatías congénitas: una revisión sistemática.

OBJECTIVE: A systematic review is presented with the objective of determining whether school children with congenital heart disease participate in psychological interventions in the cardiovascular rehabilitation process. METHOD: Guided review by the PRISMA method was carried out in the databases: Dialnet, Pub Med, Redalyc, Science Direct, Scielo, Google Academic of articles published in English, Portuguese and Spanish. The inclusion criteria are: rehabilitative interventions that contain actions for the management of psychological factors. 23 reports were evaluated for eligibility, only 1 was chosen through the data tabulation method. RESULTS: It was evidenced that these programs for children with heart disease are scarce, they focus on physical activity, neglecting socio-psychological variables. It is proposed to implement standardized intervention actions with congenital cardiovascular patients and their families from psychocardiology according to their needs.

Psychological distress, dyadic adjustment and family dynamics after prenatal diagnosis of congenital heart disease.

INTRODUCTION: Congenital heart disease (CHD) is one of the most frequent congenital diseases. When expectant fathers and mothers are informed of a CHD during pregnancy, they have to confront a series of individual and interpersonal psychological changes. The aim of the study was to evaluate the psychological impact of a prenatal diagnosis of CHD on expectant parents. The sample included 214 participants, mothers and their partners (case group, 57 pregnant women carrying a foetus with CHD and their partners and control group, 50 pregnant women and their partners). METHOD: Administration of the BSI-18, the DAS and FACES-III following prenatal diagnosis. RESULTS: Many parents (approximately 83.6%) went through stages of shock and denial in response to the diagnosis of disease that they had to confront and accept. At the individual level, 35.1% of fathers and 47.4% mothers had clinically significant scores of psychological distress. At the couple level, both fathers (77%) and mothers (82.4%) had expressed an idealized dyadic adjustment. Lastly, the perception of the family dynamic by 43.9% of fathers and 42.2% of mothers was in the mid range. CONCLUSION: The results highlight the complexity of the initial stage that these couples were going through.

Effects of patient blood management in pediatric heart surgery.

OBJECTIVE: Multidisciplinary patient blood management practices reduce costs of blood products and transfusion-related complications in hospitals. Hospital costs are high in pediatric cardiac surgery patients because high hematocrit levels are usually needed; the need for blood products is high due to complex and long surgical procedures; the length of stay in the intensive care unit (ICU) is long, and the use of treatment modalities such as dialysis and ECMO is common in this patient population. METHODS: In this retrospective study, we investigated the effects of the use of the multidisciplinary patient blood management protocols on the use of blood products and associated costs by comparing the outcomes of the protocol implemented in the year 2019 to the blood product use and costs of the previous year. In our clinic, 414 patients were operated on in 2019; 230 of them were males and 184 of them were females. RESULTS: Transfusions carried out in adherence to such protocols have reduced mortality rates along with a decline in hospital costs. CONCLUSIONS: We, too, achieved a 10% reduction in blood product costs per patient after the implementation of the multidisciplinary patient blood management protocol.

OBJETIVO: Las prácticas multidisciplinarias de manejo de la sangre del paciente reducen los costos de los productos sanguíneos y las complicaciones relacionadas con las transfusiones en los hospitales. Los costos hospitalarios son altos en pacientes pediátricos de cirugía cardíaca porque generalmente se necesitan niveles altos de hematocrito; la necesidad de hemoderivados es alta debido a los procedimientos quirúrgicos largos y complejos; la estancia en la unidad de cuidados intensivos (UCI) es larga y el uso de modalidades de tratamiento como la diálisis y la ECMO es común en esta población de pacientes. MÉTODOS: En este estudio retrospectivo; Investigamos los efectos del uso de los protocolos multidisciplinarios de manejo sanguíneo del paciente sobre el uso de hemoderivados y los costos asociados comparando los resultados del protocolo implementado en el año 2019 con el uso de hemoderivados y los costos del año anterior. En nuestra clínica se operaron 414 pacientes en 2019; 230 de ellos eran varones y 184 mujeres. RESULTADOS: Las transfusiones realizadas en cumplimiento de dichos protocolos han reducido las tasas de mortalidad junto con una disminución de los costos hospitalarios. CONCLUSIONES: Nosotros también logramos una reducción del 10% en los costos de los productos sanguíneos por paciente después de la implementación del protocolo multidisciplinario de manejo de sangre del paciente.

Comparison of echocardiography and 320-row multidetector computed tomography for the diagnosis of congenital heart disease in children.

INTRODUCTION: Echocardiography (echo) is the primary non-invasive imaging modality for the assessment of congenital heart disease (CHD). Computed tomography angiography (CTA) also has potential to examine the anatomy of complex heart anomalies as well as extracardiac involvement. OBJECTIVES: The aim of this study is to determine the impact of new CTA technology in the diagnosis of CHD and to compare echo and CTA in terms of diagnostic accuracy. METHODS: Forty-five patients who underwent preoperative echo and CTA assessment in the intensive care unit were included in this study. The results were assessed for three main types of CHD (cardiac malformations, cardiac-major vessel connections and major vessels). The main groups were also divided into subgroups according to surgical features in order to assess them more objectively. Imaging methods were compared for diagnostic accuracy, sensitivity and specificity, while surgical findings were accepted as the gold standard. RESULTS: Patients' median age and weight were two months (three days-eight years) and 12 kg (2.5-60 kg), respectively. In 45 operated cases, 205 subgroup malformations were assessed. Diagnostic accuracy was significantly greater in echo (echo vs. CTA: 98.4% and 96.2% [chi-square=6.4, p=0.011]). During surgery, 84 cardiac malformations (echo vs. CTA: 97.4% and 95.1% [chi-square=4.9, p=0.03]), 47 cardiac-major vessel connections (echo vs. CTA: 98.3% and 95.4% [chi-square=7.5, p=0.03]), and 74 major vessel malformations (echo vs. CTA: 96% and 98% [chi-square=1.8, p=0.48]) were confirmed. CONCLUSION: Echocardiography and CTA are imaging methods with high diagnostic accuracy in children with CHD. The use of echocardiography together with CTA, especially for the visualization of extracardiac anatomy, provides additional information for clinicians.

Percutaneous patent ductus arteriosus closure: Twelve years of experience.

INTRODUCTION: Patent ductus arteriosus, a persistent communication between the descending thoracic aorta and the pulmonary artery, is one of the most common congenital heart defects. Transcatheter occlusion is an effective alternative to surgery and is currently standard of care for most patients. The authors present the results from a single center after twelve years of experience using this technique. METHODS: Retrospective analysis of medical records from all patients referred to a tertiary center for percutaneous ductus closure between January 2006 and September 2018. RESULTS: A total of 221 patients were referred, with a mean age of 5.5 years-old (16 patients were infants, with the youngest aged four months). A Nit-Occlud® coil was used 139 times (62.9%), an Amplatzer™ duct occluder 79 times (35.7%), and vascular plugs were used three times. Percutaneous closure was achieved in every treated patient, with 1.4% maintaining residual shunting. Although higher overall coil device implantation was noted, duct occluder usage has been greater since 2011. Of all the coils, 55% were either 4x4 or 5x4 mm, and 73% of all Amplatzer duct occluders were either 6x4 or 8x6 mm, which correlates to the majority of patients having a small to moderately sized ductus. No complications were noted during the procedure, with a 1.8% post-procedure complication rate (one device embolization after 48 hours and three cases of loss of arterial pulse). CONCLUSIONS: Percutaneous patent ductus arteriosus closure was safe and effective in this setting, with a low global complication rate and similar outcomes to most equivalent centers.

[Psychological distress, dyadic adjustment and family dynamics after prenatal diagnosis of congenital heart disease]. / Malestar psicológico, ajuste diádico y dinámica familiar tras el diagnóstico prenatal de cardiopatía congénita.

INTRODUCTION: Congenital heart disease (CHD) is one of the most frequent congenital diseases. When expectant fathers and mothers are informed of a CHD during pregnancy, they have to confront a series of individual and interpersonal psychological changes. The aim of the study was to evaluate the psychological impact of a prenatal diagnosis of CHD on expectant parents. The sample included 214 participants, mothers and their partners (case group, 57 pregnant women carrying a foetus with CHD and their partners; and control group, 50 pregnant women and their partners). METHOD: Administration of BSI-18, DAS and FACES-III following prenatal diagnosis. RESULTS: Many parents (approximately 83.6%) went through stages of shock and denial in response to the diagnosis of disease that they had to confront and accept. At the individual level, 35.1% of fathers and 47.4% mothers had clinically significant scores of psychological distress. At the couple level, both fathers (77%) and mothers (82.4%) had expressed an idealized dyadic adjustment. Lastly, the perception of the family dynamic by 43.9% of fathers and 42.2% of mothers was in the mid-range. CONCLUSION: The results highlight the complexity of the initial stage that these couples were going through.

Spanish registry of percutaneous VSD closure with NitOcclud Lê VSD Coil device: lessons learned after more than a hundred implants.

INTRODUCTION AND OBJECTIVES: The NitOcclud Lê VSD Coil was specifically designed for transcatheter occlusion of ventricular septal defects (VSD) and became available for this purpose in August 2010. Our objective was to describe the Spanish experience of this technique and analyze its reliability and short- to mid-term efficacy. METHODS: National multicenter observational study, which retrospectively recruited all patients (of any age) with VSD (of any location or type) who underwent percutaneous NitOcclud occlusion, using an intention-to-treat analysis, until January 2019. RESULTS: A total of 117 attempts were made to implant at least 1 NitOcclud in 116 patients in 13 institutions. The median [range] age and weight was 8.6 [0.4-69] years and 27 [5.8-97] kg, respectively. In 99 patients (85%), the VSD was an isolated congenital defect. The location was perimembranous in 95 (81%), and 74 (63%) of them were aneurysmatic. The mean fluoroscopy time was 34 [11.4-124] minutes. Of the 117 attempts, 104 were successful (89%) with a follow-up of 31.4 [0.6-59] months. At the last review, final complete occlusion of the defect without residual shunt or with only a minimal shunt was achieved in 92.3% (no shunt, n=73; trivial shunt, n=23). Four patients required a second procedure for residual shunt occlusion. Two devices had to be surgically explanted due to severe hemolysis. There were no deaths or other major complications. CONCLUSIONS: The NitOcclud device can be used successfully for a wide anatomical spectrum of VSD. The main issue is residual shunt, but its incidence decreases over time. The incidence of hemolysis was very low and no permanent changes were detected in atrioventricular conduction.
