Factors associated with malnutrition in infants with congenital heart disease within one year after surgery / 中华儿科杂志

Objective: To explore the risk factors of malnutrition in infants with congenital heart disease within one year after surgery. Methods: This retrospective cohort study selected 502 infants with congenital heart disease who underwent surgical treatment in Guangzhou Women and Children's Medical Center from February 2018 to January 2019. Their basic information and clinical data were analyzed, and their nutrition status after the surgery was followed up by questionnaire survey. Weight-for-age Z score (WAZ)≤-2 one year after operation was defined as malnutrition group, and WAZ>-2 was non-malnutrition group. The perioperative indicators and complementary food advancement were compared between the two groups by chi-square test, t-test, and Kruskal-Wallis test. The risk factors of malnutrition were analyzed by Logistic regression. Results: A total of 502 infants were selected, including 301 males and 201 females, with the age of 4.1 (2.0, 6.8) months. There were 90 cases in malnutrition group and 412 cases in non-malnutrition group. The body length and weight at birth in the malnutrition group were lower than those in the non-malnutrition group ((47.8±3.8) vs. (49.3±2.5) cm, (2.7±0.6) vs.(3.0±0.5) kg, both P<0.001). The proportion of paternal high school education or above and the proportion of family per capita income of 5 000 yuan or above in the malnutrition group were lower than those in the non-malnutrition group ((18.9% (17/90) vs. 30.8% (127/412), 18.9% (17/90) vs. 33.7% (139/412), both P<0.05). Compared to the non-malnutrition group, the proportion of complex congenital heart disease in the malnutrition group was higher (62.2% (56/90) vs. 47.3% (195/412), P<0.05). The postoperative mechanical ventilation time, postoperative intensive care unit (ICU) stay time, postoperative hospital stay, total length of ICU stay and total hospital stay in the malnutrition group were significantly longer than those in non-malnutrition group (all P<0.05). The proportion of egg and fish supplementation over 2 times/week within one year after the surgery was also lower in the malnutrition group (both P<0.05). Logistic regression analysis showed that mother's weight at delivery (OR=0.95,95%CI 0.91-0.99), the pre-operative WAZ≤-2 (OR=6.04, 95%CI 3.13-11.65), the complexity of the cardiac disease (OR=2.23, 95%CI 1.22-4.06), the hospital stay after the surgery over 14 days (OR=2.61, 95%CI 1.30-5.26), the types of complementary food<4 (OR=2.57, 95%CI 1.39-4.76), and the frequency of meat and fish<2 times/week (OR=2.11, 95%CI 1.13-3.93) were the risk factors associated with malnutrition within one year after the surgery. Conclusion: Mother's weight at delivery pre-operative nutritional status, complexity of cardiac disease, postoperative hospital stay, types of daily supplements and frequency of fish are risk factors associated with malnutrition within one year after surgery in children with congenital heart disease.

Integrated management during the perinatal period for total anomalous pulmonary venous connection / 中国当代儿科杂志

OBJECTIVES@#To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography.@*METHODS@#Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology.@*RESULTS@#Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis).@*CONCLUSIONS@#TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.

Interventional treatment and early-stage follow-up of pulmonary atresia with intact ventricular septum / 中华儿科杂志

Objective: To explore the application value of percutaneous peripheral interventional therapy in pulmonary atresia with intact ventricular septal (PA-IVS). Methods: Retrospective case summary. The data was collected from 25 children who were hospitalized at the Children's Hospital,Zhejiang University School of Medicine from August 2019 to August 2022, had been diagnosed with PA-IVS by echocardiography, and underwent interventional treatment. The sex, age, weight, operation time, radiation exposure time, and radiation dose of the patients were collected. The patients were divided into the arterial duct stenting group and the non-stenting group. Preoperative tricuspid annular diameters and Z scores, right ventricular length diameters, and right ventricular/left ventricular length-diameter ratios were compared by paired t-tests. Right ventricular systolic pressure difference, oxygen saturation, lactic acid before and after the surgery were compared for 24 children who received percutaneous balloon pulmonary valvuloplasty. Right ventricular improvement in 25 children after operation was analyzed. The correlation between postoperative oxygen saturation and postoperative right ventricular systolic blood pressure difference, the degree of pulmonary valve opening and the Z value of tricuspid valve ring in the non-stenting group were analyzed. Results: A total of 25 patients with PA-IVS were enrolled in the study, of whom 19 were males and 6 females, with an age at surgery of 12 (6, 28) days and a weight of (3.7±0.5) kg. One of them underwent only stenting of the arterial duct; 20 children underwent only percutaneous pulmonary valve perforation and balloon angioplasty; 4 children underwent both procedures. The Z-value of the tricuspid ring was -1.5±1.2 in the group with arterial duct stenting, and -0.1±0.4 in the group without stenting (t=2.77, P=0.010). The tricuspid regurgitant flow rate 1 month after surgery was significantly lower than the preoperative ((3.4±0.6) vs. (4.8±0.9) m/s, t=6.62,P<0.001). In the 24 children with percutaneous pulmonary valve perforation and balloon angioplasty, the preoperative right ventricular systolic blood pressure was (110±32) mmHg, and the postoperative systolic blood pressure was (52±19) mmHg (1 mmHg=0.133 kPa) (F=59.55, P<0.001). The factors that may affect postoperative oxygen saturation in 20 cases of non-stenting group were analyzed. The results suggested that the pre and post-operative right ventricular systolic blood pressure differences (r=-0.11, P=0.649), and the pulmonary valve orifice opening (r=-0.31, P=0.201) and tricuspid annulus Z value (r=-0.18, P=0.452) at 1 month after the operation were not significantly correlated with the postoperative oxygen saturation. Conclusions: Interventional therapy can be used as the first choice for one-stage operation of PA-IVS. Percutaneous pulmonary valve perforation and balloon angioplasty are more suitable for children with well-developed right ventricles, tricuspid annulus, and pulmonary arteries. While the smaller the tricuspid annulus, the more dependent it is on the ductus arteriosus and thus patients are more suitable for arterial duct stenting.

Medium and long-term follow-up of the Pul-Stent in treating postoperative branch pulmonary artery stenosis in children with congenital heart disease / 中华儿科杂志

Objective: To evaluate the effectiveness and safety of Pul-Stent as the treatment of postoperative branch pulmonary artery stenosis in children with congenital heart disease. Methods: This was a retrospective study. Thirty-three patients who underwent Pul-Stent implantation in Shanghai Children's Medical Center due to postoperative residual pulmonary artery stenosis from August 2014 to June 2015 were included. The immediate curative effect, follow-up and complications of Pul-Stent implantation were assessed. Comparisons between groups were performed with unpaired Student t test. Results: Pul-Stent implantation of 33 patients (19 males and 14 females) were performed successfully. Thirty-one patients underwent percutaneous stenting, and 2 patients underwent hybrid stenting. A total of 35 Pul-Stents were implanted (19 of model small, 15 of model medium and one of model large), 23 stents were planted in the proximal left pulmonary artery and 12 stents were in the proximal right pulmonary artery. The initial diameter of dilation balloon ranged from 6 to 16 mm, and the long sheath of percutaneous implantation ranged from 8 to 10 F in 29 patients (29/31, 94%). After stenting, the diameter of the narrowest segment of pulmonary artery increased from (4.0±1.7) mm to (9.1±2.1) mm in all patients (t=-21.60, P<0.001). The pressure gradient at the stenosis in 26 patients after biventricular correction decreased from (30.5±12.3) mmHg (1 mmHg=0.133 kPa) to (9.9±9.6) mmHg (t=12.92, P<0.001), and the right ventricular to aortic pressure ratio decreased from 0.57±0.14 to 0.44±0.12 (t=7.44, P<0.001). The pressure of the superior vena cava after stenting in 5 patients after cavopulmonary anastomosis decreased from (17.0±1.9) mmHg to (14.0±0.7) mmHg (t=2.86, P=0.046). Two patients died during reoperation for repairing other cardiac malformations. The remaining 31 patients were clinically stable during the follow-up period of (5.3±1.6) years, and one stent fracture was found on chest X-ray. Cardiac catheterization reexaminations in 16 patients showed that restenosis was found in one stent, while stent position and patency were satisfactory in the remaining stents. Nine children underwent post-dilation without stent fracture, displacement or aneurysm formation. Cardiac tomography showed no stent stenosis, fracture observed, or significant change in diameter of the stent in 8 patients. The inner diameter and pulmonary blood perfusion could not be accurately evaluated due to artifacts by cardiac magnetic resonance imaging in 4 patients. Conclusions: Pul-Stent has good compliance and adequate radial strength, and can dilate further over time to accommodate for somatic growth. It performs safely and effectively in treating post-operative branch pulmonary artery stenosis in children.

Preliminary practice in the postoperative cardiopulmonary exercise testing for children with congenital heart disease / 中华心血管病杂志

Objective: To investigate the postoperative cardiopulmonary fitness of children with congenital heart diseases (CHD). Methods: This is a retrospective study. A total of 136 children after cardiac correction undergoing cardiopulmonary exercise test (CPET) in Shanghai Children's Medical Center from March 1 to June 30, 2021 were selected. According to the surgical procedure, the children were divided into two groups: the biventricular correction group (BV group) (n=75) and single ventricular correction group (SV group) (n=61). The BV group was divided into two subgroups: simple congenital heart disease (S-CHD) group (n=35) and complex congenital heart disease (C-CHD) group (n=40). CPET parameters, including VO2 max, VO2/kg max, VO2/kg@AT, O2/HR max, HRR, PetCO2 max, CI, HRR at 1 min, VE/VCO2 slope, OUES/kg and EOV, were analyzed. CPET parameters of patients underwent different procedure were compared. In the subgroup analysis, CPET parameters of patients in S-CHD group and C-CHD group were compared. The parameters of the BV group were compared with the normal value. Linear correlation analysis was used to identify the correlation between the CPET parameters. Results: A total of 136 children with CHD after surgery were enrolled. The age was (9.4±3.1) (ranged 6.2-16.0) years, and there was 84 (61.8%) male. All the children completed CPET examination safely without experiencing serious circulation abnormalities. Compared with the SV group, the VO2/kg max ((32.6±6.9) ml·kg-1·min-1 vs. (23.5±5.9) ml·kg-1·min-1, P<0.001), O2/HR max ((7.24±2.93) ml/beat vs. (6.35±2.17)ml/beat, P=0.030), HRR at 1 min ((32.5±13.9) beat/min vs. (26.3±12.5) beat/min, P=0.036), OUES/kg (36.9±8.8 vs. 29.7±11.8, P=0.001) were significantly higher, VE/VCO2 slope (29.1±5.20 vs. 35.1±8.0, P<0.001) and incidence of EOV (32.0%(24/75) vs. 57.4%(31/61), P=0.027) were significantly lower in BV group. Compared with the simple CHD subgroup, VE/VCO2 slope and the incidence of EOV were higher, VO2/kg max, O2/HR max, HRR at 1 min and OUES/kg were lower in the complex CHD subgroup (all P<0.05). Cardiopulmonary function parameters of the BV group were lower than the normal value. Linear correlation analysis showed that VO2/kg@AT was strongly correlated with VO2/kg max (r=0.86, P<0.001), VO2/kg max was strongly correlated with OUES/kg (r=0.63, P<0.001), HRR was strongly correlated with CI (r=0.91, P<0.001), and VO2/kg max was strongly correlated with OUES/kg (r=0.63, P<0.001). VE/VCO2 slope was strongly correlated with PetCO2 max (r=1.00, P<0.001). Conclusions: The exercise cardiopulmonary function of children after single ventricular correction is weaker than that of biventricular correction, and the exercise tolerance of children after biventricular correction is lower than that of normal children. Among the children after biventricular correction, the exercise tolerance of children with complex CHD is lower than that of children with simple CHD. Postoperative CPET is of important realistic significance for CHD children.

Risk factors for postoperative delirium in children with congenital heart disease: a prospective nested case-control study / 中国当代儿科杂志

OBJECTIVES@#To study the risk factors for postoperative delirium (POD) in children with congenital heart disease.@*METHODS@#A prospective nested case-control study was performed on children with congenital heart disease who underwent surgery in Fuwai Hospital, Chinese Academy of Medical Sciences, from December 2020 to June 2021. The clinical data were compared between the POD group (n=114) and non-POD group (n=102). A multivariate unconditional logistic regression analysis was used to investigate the risk factors for POD in children with congenital heart disease.@*RESULTS@#The multivariate logistic regression analysis showed that age (OR=0.951, P<0.001), gender (OR=2.127, P=0.049), number of invasive catheters per day (OR=1.490, P=0.017), degree of postoperative pain (OR=5.856, P<0.001), and preoperative parental anxiety level (OR=1.025, P=0.010) were independent risk factors for POD in children with congenital heart disease.@*CONCLUSIONS@#The risk of POD increases in children with congenital heart disease who are younger, male, have higher number of invasive catheters per day, higher degree of postoperative pain, or higher preoperative parental anxiety level.

Central venous oxygen saturation/lactate ratio and prediction of major adverse events after pediatric heart surgery

Abstract Introduction: Major adverse events (MAE) are unexpected but undesirably frequent after pediatric congenital heart surgery and contribute to poorer outcomes. The aim of this study was to test the predictive value of a ratio between central venous oxygen saturation and arterial lactate (ScvO2/lactate) for MAE after pediatric congenital heart surgery in a Brazilian university hospital. Methods: We conducted a retrospective observational study in a tertiary care university hospital, including 194 infants and children submitted to surgery for congenital heart disease. The predictive value of ScvO2, lactate, and ScvO2/lactate ratio were assessed by the area under the receiver operating characteristics curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Results: The incidence of MAE was 16% — cardiac arrest/death, unplanned reoperation, and low cardiac output syndrome were the most common events. Overall, ScvO2/lactate ratio discriminated patients with and without MAE very well (AUC 0.842), performing better than either variable alone, with sensitivity of 48%, specificity of 94%, PPV of 60%, and NPV of 91%. Conclusion: A ScvO2/lactate ratio > 5 can accurately identify patients at low risk of MAE after pediatric congenital heart surgery, with very good specificity and NPV, but poor sensitivity and PPV.

WeChat-Assisted Preoperative Health Education Reduces Burden of Care on Parents of Children with Simple Congenital Heart Disease: a Prospective Randomized Controlled Study

Abstract Objective: The purpose of this study was to explore the clinical effect of preoperative health education based on the WeChat platform for parents of children with simple congenital heart disease. Methods: In this study, participants were randomly divided into an intervention group (WeChat group, n=40) and a control group (leaflet group, n=40) in our center. All parents were required to complete the Family Caregiver Task Inventory (FCTI) on the first visit and the Zarit Burden Interview (ZBI) and FCTI before the operation. Clinical, family and relevant data from children and parents were collected and subsequently analyzed. Results: Before the operation, the FCTI score and the ZBI score in the WeChat group were significantly lower than those in the control group (P=0.010, P=0.027, respectively). Compared to the FCTI score on the first visit, the preoperative status score was significantly lower in the WeChat group (P=0.008). The rate of loss to follow-up and complications in the WeChat group was also significantly lower than in the control group (P=0.003). Conclusion: Preoperative health education assisted by the WeChat platform for parents of children with simple congenital heart disease can effectively improve the parents' care ability and reduce the burden of care, preoperative complications and the rate of loss to follow-up.

Abstract Introduction: The anomalous origin of one of the branches of the pulmonary artery from the ascending aorta is rare. Objective: To identify the clinical and surgical characteristics of the patients undergoing reimplantation of the affected branch. Method: An observational, cross-sectional, descriptive, retrospective and retrolective study was performed; patients diagnosed with anomalous origin of one of the branches of the pulmonary artery and treated by corrective surgery at the Instituto Nacional de Cardiología Ignacio Chavez, in the period from January 1, 2003 to January 31, 2019, were included. It was extracted from the files: demographic characteristics, surgical antecedents, diagnoses, echocardiographic and tomographic reports, surgical technique and post-surgical status. Results: Nine patients underwent correction surgery, with an average age of 2 ± 2 years, 11.4 ± 1.5 kg and height 82 ± 15 cm; 67% were male. The most frequent affected branch was the right, 68% originated directly from the aorta and 42% from a patent ductus arteriosus. The correction with extracorporeal circulation had an average aortic cross-clamp of 35 minutes and circulatory support of 45 minutes, the direct or synthetic implant was used. The complications were ventricular failure, bleeding, arrhythmias and nosocomial pneumonia. Mortality was 11%. Conclusions: Surgical treatment for reimplantation of the anomalous branch of the pulmonary artery is the procedure of choice, which with surgical and subsequent care has a good prognosis in the medium and long term.

Glenn surgery: a safe procedure in the path of univentricular correction / Cirugía de Glenn: un procedimiento seguro en el camino de la corrección univentricular

Abstract Background: This study describes 35 years of experience in a tertiary care level hospital that treats cardiac patients with univentricular heart physiology who underwent Glenn surgery. Methods: The study consisted of a retrospective analysis of patients who underwent Glenn surgery, including variables related to pre-operative, intra-operative, and post-operative morbidity and mortality. Results: From 1980 to 2015, 204 Glenn surgeries were performed. The most common heart disease was tricuspid atresia IB (19.2%). In 48.1% of the cases, the procedure was performed with antegrade flow. A bilateral Glenn procedure was performed in 12.5% of the cases and 10.3% were carried out without using a cardiopulmonary bypass pump. Reported complications included infections, bleeding, arrhythmias, chylothorax, neurological alterations, and pleural effusion. The mortality rate was 2.9% Conclusions: Glenn surgery is a palliative surgery with good results. It significantly improves patient quality of life over a long period until a total cavopulmonary shunt is performed. The complications observed are few, and the mortality rate is low. Therefore, it is a safe surgery that should be used for univentricular congenital heart disease.

Resumen Introducción: El objetivo de este trabajo fue describir la experiencia de 35 años en un hospital de tercer nivel con pacientes cardiópatas con fisiología univentricular que fueron sometidos a cirugía de Glenn. Métodos: Se presenta un análisis retrospectivo de los pacientes sometidos a cirugía de Glenn. Se incluyeron variables relacionadas con la morbilidad y la mortalidad preoperatorias, transoperatorias y posoperatorias. Resultados: Desde 1980 hasta 2015 se realizaron 204 cirugías de Glenn para la corrección de cardiopatías. De ellas, la más frecuente fue la atresia tricuspídea IB (19.2%); en el 48.1% se realizó Glenn con flujo anterógrado, en el 12.5% Glenn bilateral y el 10.3% de las cirugías fueron sin apoyo de bomba de circulación extracorpórea. Las complicaciones reportadas fueron infecciones, sangrado, arritmias, quilotórax, alteraciones neurológicas y derrame pleural. La mortalidad fue del 2.9%. Conclusiones: La cirugía de Glenn es un procedimiento paliativo que se ha utilizado con buenos resultados. Mejora en forma importante la calidad de vida del paciente durante un largo periodo mientras que se realiza la derivación cavopulmonar total. Presenta pocas complicaciones y muy baja mortalidad, por lo que es una cirugía segura que debe ser utilizada para cardiopatías congénitas univentriculares.

Efectos de la impresión 3D en la planificación quirúrgica de las cardiopatías congénitas / Impact of 3D printing in surgical planning of congenital heart disease

Resumen Introducción: Los defectos cardíacos congénitos constituyen el 30% de todas las anomalías congénitas. La prevalencia es de 8/1,000 recién nacidos vivos, sin predominio de género. Para una planificación quirúrgica óptima es esencial una evaluación precisa de la anatomía en los defectos cardíacos congénitos. Las modalidades de imagen como el ecocardiograma, la angiografía por cateterismo cardíaco, la tomografía computarizada (TC) o la resonancia magnética (RM) se utilizan de forma regular para el diagnóstico de las cardiopatías congénitas. Estos métodos pueden proporcionar reconstrucciones virtuales en reconstrucción volumétrica o 3D, pero no réplicas táctiles reales de la anatomía cardíaca. Objetivo: Realizar modelos de corazón impresos en 3D con la finalidad de proporcionar réplicas táctiles 3D reales de la anatomía cardíaca para visualizar de forma detallada todas las perspectivas posibles de las estructuras extracardíacas o intracardíacas. Métodos: Los datos de la imagen se obtuvieron en formato DICOM, se editaron en el paquete de software "3D slicer 4.3" y se exportaron para la impresión en formato de archivo (.stl). Resultados y conclusiones: Con la impresión 3D se puede evaluar de forma detallada la anatomía intracardíaca y extracardíaca con modelos cardíacos en tiempo real. Esta técnica es de gran utilidad, sobre todo en los defectos cardíacos congénitos complejos, ya que permite hacer una planificación precisa del procedimiento quirúrgico.

Abstract Introduction: Congenital heart disease makes up for 30% of all congenital anomalies. The prevalence is 8/1,000 live newborns, without predominance of gender. Imaging methods such as echocardiography, angiography, computed tomography or magnetic resonance imaging must be routinely used in congenital heart disease. The mentioned methods can provide virtual reconstructions in volumetric reconstruction or in three dimensional (3D), but only 3D-printed heart models can provide real 3D tactile replicas of cardiac anatomy. Objective: To make 3D printed heart models in order to provide real 3D tactile replicas of the cardiac anatomy that allow a detailed visualization from all possible perspectives, either of extracardiac or intracardiac structures. Methods: This information is useful for surgical decision making, especially in patients with complex cardiac defects. DICOM, edited in a software package "3D slicer 4.3" and exported for printing in file format (.stl). Results and conclusions: With 3D printing, the intracardiac and extracardiac anatomy can be evaluated in detail with real-scale cardiac models of the patient, avoiding unexpected findings. This technique is very useful especially in complex congenital heart defects, since it allows precise planning of the surgical procedure.

Quality of life of children and adults following cardiac surgery for congenital heart disease: A Mexican cohort / Calidad de vida en niños y adultos después de cirugía para cardiopatías congénitas: primera cohorte mexicana

Abstract Objective: The real burden of (congenital heart defects [CHD]) and the improvement after surgical correction or palliation is both reflected in the quality of life (QoL). There are few studies in Latin-America that evaluate QoL in the CHD population. The purpose of this study was to measure the QoL after corrective or palliative surgery for CHD. Materials and methods: An observational, cross-sectional, and comparative study was carried out at the Miguel Hidalgo Centennial Hospital. Patients from 8 to 18 years old who underwent surgery for CHD were included during a period of 8 months. A total of 40 patients were included, together with a group of 80 healthy controls. From all participants, a KIDSCREEN-52 questionnaire was taken. A comparative analysis of the results was performed. Results: Overall, patients with cardiac surgery had better QoL indexes than healthy controls (p < 0.0001). The difference was greatest in moods and emotions, autonomy, and parent relations. Conclusions: Self-perception of QoL in post-operative patients for congenital heart disease is similar and in certain dimensions higher than the healthy population, possibly due to socioeconomic differences, parental care, and styles of coping with their disease. Higher complexity studies that include psychosocial variables and parental perception are required, and a better understanding of the QoL determinants will improve the attention provided to the patient and their families.

Resumen Objetivo: Los efectos de las cardiopatías congénitas en los pacientes, así como la mejoría después de la paliación o la corrección quirúrgica, se reflejan en la calidad de vida (CV). Hay pocos estudios en Latinoamérica que evalúen la CV en esta población. El objetivo de este artículo es notificar la CV posterior a la operación paliativa o correctiva para defectos cardíacos congénitos. Material y métodos: Se llevó a cabo un estudio observacional, transversal y comparativo en el Centenario Hospital Miguel Hidalgo. Durante un período de ocho meses se incluyó a pacientes de 8 a 18 años sometidos a una intervención para cardiopatías congénitas. Se reunió a dos grupos de 40 pacientes y 80 controles sanos, pareados por edad y sexo. A cada participante se le aplicó el cuestionario KIDSCREEN-52 y se realizó un análisis comparativo de los resultados. Resultados: Los pacientes sometidos a operación cardíaca tuvieron mejores índices de CV que los controles sanos (p < 0.0001). La mayor diferencia se obtuvo en los aspectos de estado de ánimo y emociones, autonomía y relación con los padres. Conclusiones: La autopercepción de la CV después de una intervención para cardiopatías congénitas es similar y, en ciertas dimensiones, mejor que la de la población sana, tal vez por diferencias socioeconómicas, atención de los padres y modelos de adaptación a la enfermedad. Se requieren estudios más extensos que incluyan variables psicosociales y percepción parental. Una mayor comprensión de los determinantes de la CV podría mejorar la atención ofrecida al paciente y su familia.

Avaliação da deglutição e indicadores clínicos associados em crianças após correção cirúrgica de doença cardíaca congênita / Evaluation of swallowing and associated clinical markers in infants after surgical repair of congenital heart disease

RESUMO Objetivo Identificar os marcadores clínicos associados às alterações da deglutição em crianças após a correção da doença cardíaca congênita e correlacionar esses marcadores às categorias da escala Risk Adjustment for Congenital Heart Surgery 1 (RACHS-1). Métodos Foi realizado um estudo retrospectivo observacional, utilizando a base de dados eletrônica do centro de pediatria para crianças admitidas em um hospital, em decorrência de doença cardíaca congênita. Foram coletados dados da avaliação de deglutição e a presença de disfagia foi classificada de acordo com a Dysphagia Management Staging Scale (DMMS). Foram incluídos os dados demográficos, os marcadores clínicos e o risco de mortalidade, de acordo com a RACHS-1. Resultados A amostra final do estudo foi composta por 108 pacientes. Os achados mais relevantes foram: os sinais mais graves de disfagia estiveram associados ao aumento da permanência no hospital (p=0,005); ao maior número e tempo de intubações orotraqueais (p=0,022 e 0,005, respectivamente); ao maior tempo entre a admissão hospitalar e a avaliação da deglutição (p=0,003); ao maior tempo entre o procedimento cirúrgico e a avaliação da deglutição (p=0,043) e ao maior número de sessões fonoaudiológicas para remoção da via alternativa de alimentação e retorno seguro para via oral (p<0,001). Não foram encontradas correlações entre o risco de mortalidade das crianças e os sinais alterados na avaliação da deglutição. Conclusão Os resultados do estudo contribuem para o conhecimento atual de que crianças com doenças cardíacas que precisam de correção cirúrgica apresentam dificuldades alimentares e necessitam atendimento hospitalar prolongado. Não houve correlação entre as categorias da escala RACHS-1 e os sinais de alteração na avaliação clínica da deglutição.

ABSTRACT Purpose To identify clinical markers that are associated to swallowing alterations in infants after surgical repair of congenital heart disease (CHD) and to correlate these markers to the categories on the Risk Adjustment for Congenital Heart Disease 1 (RACHS-1) scale. Methods Using the Pediatric Center Database System we conducted a retrospective, observational cohort study on children admitted to the pediatric hospital unit due to CDH. We collected data on specific parameters of a clinical swallowing assessment (SA) and dysphagia was classified according to the Dysphagia Management Staging Scale. We also included demographic and clinical markers and patient´s risk of mortality was determined by using the RACHS-1. Results The final study sample consisted of 108 patients. Important findings were: the more severe signs of dysphagia are associated to an increased length of hospital stay (p=0.005); an increased number and duration of orotracheal intubation (p=0.022 and 0.005 respectively); an increased time between hospital admission and SA (p=0.003); an increased time between the surgical procedure and swallowing assessment (0.043); and an increased number of SLP sessions to remove alternate feeding methods and warrant safe oral feeding (p<0.001). No correlations were observed between the infant's risk of mortality and the altered sings on the clinical swallowing assessment. Conclusion The data from this study contributes to the current knowledge that children with heart condition requiring heart surgery in the first month of life have high risk of presenting feeding difficulties and will require prolonged hospital care. No correlation was observed between the categories on RACHS-1 and the altered signs on the clinical swallowing assessment.

Primary peritoneal drainage in neonates with necrotizing enterocolitis associated with congenital heart disease: a single experience in a Brazilian tertiary center

Necrotizing enterocolitis (NEC) is a common condition in preterm infants. The risk factors that contribute to NEC include asphyxia, apnea, hypotension, sepsis, and congenital heart diseases (CHD). The objective of this study was to evaluate the association between the treatment (surgery or drainage) and unfavorable outcomes in neonates with NEC and congenital heart diseases (NEC+CHD). A 19-year retrospective cohort study was conducted (2000-2019). Inclusion criterion was NEC Bell II stage. Exclusion criteria were associated malformation or genetic syndrome and those who did not undergo echocardiography or had a Bell I diagnosis. We included 100 neonates: NEC (n=52) and NEC+CHD (n=48). The groups were subdivided into NEC patients undergoing surgery (NECS, n=31), NEC patients undergoing peritoneal drainage (NECD, n=19), NEC+CHD patients undergoing surgery (NECCAS, n=21), and NEC+CHD patients who were drained (NECCAD, n=29). Multivariate analysis was performed to estimate the relative risk of death and the length of stay. Covariates were birth weight and gestational age. The group characteristics were similar. The adjusted relative risk of death was higher in the drainage groups [NECD (Adj RR=2.70 (95%CI: 1.47; 4.97) and NECCAD (Adj RR=1.97 (95%CI: 1.08; 3.61)], and they had the shortest time to death: NECD=8.72 (95%CI: 3.10; 24.54) and NECCAD=5.32 (95%CI: 1.95; 14.44). We concluded that performing primary peritoneal drainage in neonates with or without CHD did not improve the number of days of life, did not decrease the risk of death, and was associated with a higher mortality in newborns with NEC and clinical instability.
