ABSTRACT

Abstract Objective To analyze the most frequent referrals for fetal echocardiography, including advanced maternal age and its association with abnormal results. Methods We included all pregnant women referred to perform fetal echocardiography (gestational age 22-32 weeks) in 2 health centers in Rio de Janeiro, from June 2015 to June 2016. Advanced maternal age was considered when age was > 35 years at the time of delivery). Referral reasons and results were recorded, according to the Brazilian Fetal Cardiology Statement. Crude and adjusted prevalence ratios were calculated (Poisson regression). We considered p < 0.05 as significant. Results A total of 1,221 tests were analyzed. Abnormal fetal echocardiography was observed in 14.82% of the cases. The most frequent abnormalities were interventricular septal defect (6.39%), septal hypertrophy (3.35%) and atrioventricular septal defect (1.14%). Routine exams were performed in 559 women, 289 were referred for advanced maternal age and 373 were referred according to the Brazilian FetalCardiology Statement criteria. An obstetric ultrasound suggesting fetal cardiacabnormality, maternal diabetes, increased nuchal translucency, and obstetric ultrasound suggesting a noncardiac abnormality were strongly associated with an abnormal fetal echocardiography. Abnormal results were not more frequent in women with advanced maternal age when compared with the rest of the study group. Conclusions It was observed that routine exams and advancedmaternal age referrals were very frequent. Those exams were not associated to fetal echocardiography abnormalities. In this scenario, when the obstetric ultrasound suggests a fetal cardiac


Resumo Objetivo Analisar as indicações mais frequentes para realização de ecocardiografia fetal, incluindo idade materna avançada, e a associação destas com exames alterados. Métodos Foram incluídas todas as gestantes que realizaram ecocardiografia fetal na idade gestacional entre 22 e 32 semanas, em 2 centros de referência no Rio de Janeiro, no período de junho de 2015 a junho de 2016. Foi considerada idadematerna avançada se no momento do parto a idade materna fosse> 35 anos. As indicações e os resultados dos exames foram registrados, segundo a Diretriz Brasileira de Cardiologia Fetal. Foramcalculadas as razões de prevalência brutas e ajustadas através da regressão de Poisson, considerando-se p < 0,05. Resultados Um total de 1.221 exames foram analisados. A frequência de exame ecocardiográfico alterado foi 14,82%. As alterações mais frequentes foram defeito do septo interventricular (6,39%), hipertrofia septal (3,35%) e defeito do septo atrioventricular (1,14%). Quinhentos e cinquenta e nove exames foram realizados com indicação de rotina, 289 por idade materna avançada e 373 preenchiam critério de acordo com a Diretriz Brasileira de Cardiologia Fetal. O exame ecocardiográfico alterado foi associado ao ultrassom obstétrico sugerindo cardiopatia fetal, ao diabetes materno, à translucência nucal aumentada e ao ultrassom obstétrico sugerindo alteração extracardíaca. Não foi observada maior frequência de exame ecocardiográfico alterado nas gestantes com idade materna avançada, comparado ao restante da amostra. Conclusão Constatou-se elevada frequência de indicações de rotina, e por idade materna avançada isoladamente, que não foram associados a alterações da ecocardiografia fetal. Em nosso meio, quando o ultrassom obstétrico sugere cardiopatia fetal, é muito provável que a ecocardiografia fetal tambémseja anormal. Portanto, o ultrassom obstétrico é um bom método de rastreio pré-natal.

ABSTRACT

RESUMEN Introducción: el interés de la visualización sonográfica del timo fetal está relacionado con su importante función inmunológica, las posibilidades de diagnóstico que ofrecen los ecógrafos de alta resolución, y el incremento de informes de posibles afecciones durante el proceso de la gestación. Objetivo: determinar la frecuencia de la hipoplasia tímica fetal en gestantes de riesgo genético y relacionarla con la presencia de defectos fetales, factores de riesgo previos y aparición de efectos obstétricos adversos. Métodos: se realizó un estudio descriptivo prospectivo consistente en la evaluación ecográfica del timo fetal mediante el índice timo-tórax a 221 gestantes que acudieron a los servicios de referencia del Centro Provincial de Genética Médica, por presentar riesgo genético incrementado para cardiopatías. Resultados: se encontraron 16 fetos con un índice timo-tórax inferior o igual a 0,30, el cual se utilizó como criterio de hipoplasia tímica en este estudio, entre ellos: 4 con cardiopatías, 4 con cromosomopatías, 1 con malformación estructural aislada, 2 con preeclampsia, 1 con crecimiento intrauterino retardado, 1 pretérmino y una muerte fetal. Los motivos de referencia con mayor proporción de positividad fueron: la traslucencia nucal aumentada y la imagen de sospecha de cardiopatía congénita en ultrasonido de pesquisaje. Conclusiones: la determinación del índice timo-tórax permitió el diagnóstico de la hipoplasia tímica, tanto en el segundo como en el tercer trimestre de la gestación. Este tipo de investigación es relevante pues contribuye a identificar: defectos congénitos, factores de riesgo y efectos obstétricos adversos.


ABSTRACT Introduction: the interest in sonographic visualization of the fetal thymus is related to its important immunological function, the diagnostic possibilities offered by high-resolution ultrasound scanners, and the increased reporting of possible conditions during the gestation process. Objective: to determine the frequency of fetal thymic hypoplasia in pregnant women with genetic risks and to relate it to the presence of fetal defects, previous risk factors and the appearance of adverse obstetric effects. Methods: we conducted a prospective descriptive study consisting of the ultrasound evaluation of the fetal thymus by means of the thymic-thoracic ratio in 221 pregnant women who come to referral services of the Provincial Center of Medical Genetics, because they presented increased genetic risk for heart disease. Results: sixteen fetuses were found with a thymic-thoracic ratio less than or equal to 0.30, which was used as the criterion for thymic hypoplasia in this study: four with heart diseases, four with chromosomal diseases, one with isolated structural malformation, two with preeclampsia, one with delayed intrauterine growth, one preterm and one fetal death. The reference reasons with the highest proportion of positivity were: increased nuchal translucency and image of suspected congenital cardiopathy in screening ultrasound. Conclusions: determination of the thymic-thoracic ratio allowed us the diagnosis of thymic hypoplasia, both in the second and third trimester of pregnancy. This type of research is relevant because it helps to identify: congenital defects, risk factors and adverse obstetric effects.

ABSTRACT

La hernia diafragmática congénita (HDC) es una enfermedad de baja prevalencia, con elevada morbimortalidad. Los factores pronósticos posnatales, durante el primer día de vida, son útiles para la toma de decisiones.Objetivos. Determinar la capacidad predictiva de los factores posnatales ecocardiográficos, clínicos y bioquímicos de mortalidad en los recién nacidos con HDC durante el primer día de vida.Método. Estudio observacional analítico de cohorte retrospectiva. Se incluyeron los pacientes con HDC, en forma consecutiva, desde marzo de 2012 a noviembre de 2018. Se analizaron como predictores el índice de oxigenación (IO), valor más alto de presión parcial de dióxido de carbono en sangre (pCO2), puntaje de gravedad SNAPPE II, ecocardiograma, dosaje de NT-pro péptido natriurético B (NT-proPNB), todos medidos en el primer día de vida.Resultados. La población fue de 178 pacientes con HDC. La sobrevida, del 75 %. El 24 % recibió oxigenación por membrana extracorpórea. La presencia precoz de hipertensión pulmonar sistémica o suprasistémica no mostró capacidad predictiva (OR 2,2; IC 95 %: 0,8-8), p = 0,1. NT-proPNB tampoco mostró buena discriminación (área bajo la curva (ABC) 0,46, p = 0,67). El IO, SNAPPE II y el valor más alto de pCO2 mostraron buena discriminación, ABC IO 0,82, ABC SNAPPE II 0,86 y ABC pCO2 0,75, p < 0,001.Conclusión.SNAPPE II, IO y valor más alto de pCO2, medidos el primer día de vida, mostraron buena capacidad predictiva con respecto a la evolución; SNAPPE II fue superior al IO y al valor más alto de CO2.


Introduction: Congenital diaphragmatic hernia (CDH) prevalence is low while its associated morbidity and mortality rates are high. Postnatal prognostic factors on the first day of life are useful for predicting the outcome. Objectives: To determine the mortality predictive ability of postnatal echocardiographic, clinical, and biochemical factors among newborn infants with CDH in their first day of life. Method: Observational analytical study of a retrospective cohort. Patients with CDH were consecutively included between March 2012 and November 2018. On the first day of life, analyzed predictors were the oxygenation index (OI), the highest partial pressure of carbon dioxide (pCO2) level in blood, the SNAPPE II severity score, the echocardiography, and the N-terminal pro-B-type natriuretic peptide (NTproBNP) value. Results: The population consisted of 178 patients with CDH. Survival was 75 %. Extracorporeal membrane oxygenation was used in 24 %. The early onset of systemic or suprasystemic pulmonary hypertension showed no predictive ability (OR: 2.2, 95 % CI: 0.8-8), p = 0.1. NT-proBNP did not show good discrimination either (area under the curve [AUC]: 0.46, p = 0.67). The OI, SNAPPE II score, and the highest pCO2 level showed adequate discrimination power, AUC for OI: 0.82, AUC for SNAPPE II: 0.86, and AUC for pCO2: 0.75, p < 0.001. Conclusion: The SNAPPE II score, the OI, and the highest pCO2 level measured on the first day of life, showed a good predictive ability in terms of the course of the disease; the SNAPPE II score was better than the OI and the highest pCO2 level.

ABSTRACT

Dentro de las malformaciones congénitas, las cardiopatías son las anomalías más frecuentes y se asocian a una elevada morbimortalidad perinatal y a largo plazo. El objetivo de esta actualización es revisar la tasa de detección prenatal, las características del tamizaje a lo largo del embarazo, tanto en el primero como en el segundo trimestre, las indicaciones de ecocardiografía avanzada, y establecer un algoritmo de manejo ante el diagnóstico prenatal de una cardiopatía congénita. Se discutirán los estudios invasivos y no invasivos que pueden realizarse y el seguimiento obstétrico. Finalmente, se revisarán las características principales de la terapia fetal en anomalías cardíacas, tanto intervencionismo cardíaco como el tratamiento intrauterino de las arritmias.


Among congenital malformations, heart defects are the most common type of anomaly, and these are associated with a high perinatal, long-term morbidity and mortality. The objective of this update was to review the rate of prenatal detection, screening characteristics throughout the pregnancy, in both the first and second trimesters, indications for advanced echocardiography, and to establish a management algorithm in case of prenatal diagnosis of a congenital heart disease. Potential invasive and non-invasive tests and obstetric follow-up will be discussed here. Finally, the main characteristics of fetal therapy in heart anomalies will be reviewed, both cardiac interventions and intrauterine treatment of arrhythmias.

ABSTRACT

Resumen Introducción: Aún existe controversia sobre la utilidad de la ecocardiografía funcional (EcoFn) en la valoración cardiovascular de neonatos críticamente enfermos. Objetivo: Analizar la utilidad de la EcoFn en la modificación de tratamiento en neonatos ingresados a una Unidad de Cuidados Intensivos Neonatales (UCIN). Material y métodos: Estudio prospectivo en una UCIN durante un año mediante EcoFn realizada por un cardiólogo capacitado en pacientes en sus primeras 72 horas de vida extrauterina, con valoración de la funcionalidad cardiaca y presencia de alteraciones estructurales. Con base en los hallazgos se analizaron las modificaciones al tratamiento. Resultados: 37 neonatos fueron evaluados con EcoFn en dos ocasiones: una diagnóstica y otra de seguimiento. En 11 (29.7%) se encontró daño estructural y funcional, en 9 (24.3%) solo funcional, en 7 (18.9%) solo estructural y en 10 (27%) no se observaron alteraciones. En el 70% se realizó al menos un cambio de tratamiento. Los cambios más frecuentes fueron modificaciones al apoyo ventilatorio (63%), seguido del apoyo aminérgico (19.5%) y modificaciones en el aporte de líquidos (10.8%). En todos los casos los cambios mejoraron las condiciones clínicas de los neonatos. Conclusiones: La EcoFn permitió determinar mejor las condiciones estructurales y hemodinámicas de los pacientes y realizar modificaciones terapéuticas más precisas.


Abstract Introduction: It is still controversy about the usefulness of functional echocardiography (FnEC) in critically ill neonates. Objective: To analyze the usefulness of the FnEC in the treatment decisions in neonates admitted to a Neonatal Intensive Care Unit (NICU). Materials and methods: A year prospective study in a NICU. A trained cardiologist performed a FnEC to 72 h of life patients to evaluate the cardiac function and heart structure. We analyzed the clinical decisions after the findings. Results: 37 neonates underwent two FnEC: at the diagnosis and at follow-up. Eleven patients (29.7%) had structural and functional abnormalities, 9 (24.3%) only functional, 7 (18.9%) only structural, and in the rest, 10 (27%), were normal. Al least one change in the management occurred in 70% of the patients. The main changes were to the ventilatory support (63%), followed by inotropic support (19.5%) and fluid intake (10.8%). In all changes, we observed an improvement in the clinical conditions of the neonates. Conclusions: The FnEC allowed to determinate the cardiovascular structures and hemodynamic conditions of the patients and make a more precise therapeutic modifications.

ABSTRACT

Abstract Clinical data: Infant, 7 months, female, referred to our department at one month of age, suspecting of congenital heart disease for further investigation. Chest radiography: Demonstrates cardiomegaly and prominent pulmonary vascular markings. Electrocardiography: Shows right ventricular hypertrophy and left anterior fascicular block. Echocardiography: Evidenced common atrioventricular valve with two orifices and the left superior pulmonary vein draining on the brachiocephalic vein. Computed tomography angiography: This complementary imaging exam was performed to confirm the diagnosis. Diagnosis: The patient presented an association between AVSD and PAPVC, a rare combination. The clinical picture of heart failure was preponderant, characterized by need for diuretics and complementary exams findings, and early surgical treatment was indicated. Operation: The operation was performed through a median sternotomy with 123 minutes of cardiopulmonary bypass and 89 minutes of cross-clamping time. The patient had no postoperative complications, remaining 10 days hospitalized.

ABSTRACT

Abstract Background and objectives: Cardiac Magnetic Resonance Imaging (MRI) is a technique used for evaluation of children with congenital heart diseases. General anesthesia ensures immobility, particularly in uncooperative patients. However, chest wall movements can limit good quality scans. Prolonged apnea may be necessary to decrease respiratory motion artefacts, potentially leading to hypoxemia and other adverse events. The use of a high frequency jet ventilator may be a solution avoiding chest wall movements. Case report: We report four cases of pediatric patients, ASA II, aged between 4 and 15 years-old, scheduled for cardiac MRI. General anesthesia was proposed and parental informed consent was obtained. After general anesthesia was induced, an uncuffed endotracheal tube was inserted. Then, a 7Fr × 40 cm catheter was placed through the endotracheal tube. The proximal outlet of the catheter was attached through a connecting tube to a high frequency jet ventilator (Monsoon III®, Acutronic Medical Systems). Good quality MRI images were obtained. At the end of the procedures, we observed increased salivation and increased end-tidal CO2 (60-70 mmHg), in all patients. The patients were extubated after normocapnia was achieved and neuromuscular blockade reversed. Following appropriate recovery time, the four children were discharged home the same day. Conclusions: This case series demonstrates that the use of a high frequency jet ventilator for cardiac MRI was feasible, safe, providing good quality cardiac imaging and avoiding anesthesia personnel to be inside the hazardous environment of MRI room. Future studies are needed to confirm its safety and efficiency in pediatric patients.


Resumo Justificativa e objetivos: A ressonância magnética (RM) cardíaca é uma técnica usada na avaliação de crianças com cardiopatias congênitas. A anestesia geral garante imobilidade, especialmente em pacientes não cooperadores, porém os movimentos da parede torácica podem limitar a boa qualidade dos exames. A apneia prolongada pode ser necessária para diminuir os artefatos do movimento respiratório, potencialmente levando à hipoxemia e outros eventos adversos. O uso de ventilação a jato de alta frequência pode ser uma solução para evitar os movimentos da parede torácica. Relato de caso: Relatamos quatro casos de pacientes pediátricos, ASA II, entre 4-15 anos, programados para ressonância magnética cardíaca. Uma anestesia geral foi proposta e assinaturas em termo de consentimento livre e esclarecido foram obtidas dos pais. Após a indução da anestesia geral, um tubo endotraqueal sem balonete foi inserido. Em seguida, um cateter de 7Fr × 40 cm foi inserido através do tubo endotraqueal. A saída proximal do cateter foi conectada, mediante um tubo conector, a um sistema de ventilação a jato de alta frequência (Monsoon III®, Acutronic Medical Systems). Imagens de ressonância magnética de boa qualidade foram obtidas. No fim dos procedimentos, observamos aumento tanto de salivação quanto de CO2 expirado (60-70 mmHg) em todos os pacientes. Os pacientes foram extubados após a obtenção de normocapnia e reversão do bloqueio neuromuscular. Após o tempo de recuperação apropriado, as quatro crianças receberam alta no mesmo dia. Conclusões: Esta série de casos demonstra que o uso de um sistema de ventilação a jato de alta frequência para ressonância magnética cardíaca é viável e seguro, além de fornecer imagens cardíacas de boa qualidade e evitar a presença da equipe de anestesia dentro do ambiente de risco da sala de ressonância magnética. Estudos futuros são necessários para confirmar sua segurança e eficiência em pacientes pediátricos.

ABSTRACT

Abstract Quadricuspid aortic valve (QAV) is a rare cardiac malformation. Many cases are incidentally diagnosed in aortic surgeries or autopsies and it usually appears as an isolated anomaly. The most widely classification used is the one by Hurwitz and Roberts[1], which divides 7 alphabetical subtypes based on the cusps size. The aim of this report is to describe three different anatomic presentations of this rare aortic valve anomaly.

ABSTRACT

Abstract The complete or the partial absence of pericardium is a rare congenital malformation for which the patients are commonly asymptomatic and the diagnosis is incidental. The absence of the left side of the pericardium is the most common anomaly that is reported in the literature while the complete absence of pericardium or the absence of the right side of the pericardium are uncommon and their criteria are still unrecognized given their rare occurrence in clinical practice. This paper aims to report a case of 19-year-old male with the congenital partial absence of both sides of the pericardium and to highlight the symptoms and the different cardiac imaging modalities used to confirm the diagnosis of this defect.

ABSTRACT

Las cardiopatías congénitas presentan con frecuencia patrones anatómicos complejos y tradicionalmente se han estudiado con ecocardiografía y eventualmente con cateterismo cardíaco. Con los avances tecnológicos de las últimas décadas, la tomografía computada y la resonancia magnética nuclear han adquirido gran importancia en la evaluación cardíaca. Actualmente constituyen métodos utilizados en el estudio de variadas patologías cardiovasculares de la infancia de difícil diagnóstico ecográfico, que previamente eran evaluadas por angiografía convencional, lo cual implicaba una dosis de radiación mucho mayor (AU)


Congenital heart defects often have complex anatomical patterns and have traditionally been studied with echocardiography and eventually cardiac catheterization. With technological advances in recent decades, computed tomography and magnetic resonance imaging have become very important in cardiac evaluation. Currently, they are the methods of choice in the study of a wide range of childhood cardiovascular diseases that are difficult to diagnose with echocardiography, which were previously evaluated using conventional angiography, involving a much higher dose of radiation (AU)
