Extracorporeal membrane oxygenation support in children with severe coronavirus disease-2019: A case series.

Background: The coronavirus disease-2019 (COVID-19) pandemic has predominantly affected the adult population, but with a significantly lower prevalence in children. Most pediatric patients with COVID-19 have mild course; however, a small number progressed to acute respiratory distress syndrome, hypoxemia, despite optimized conventional therapies. Thus, this study aimed to report a series of six cases of children with severe acute respiratory syndrome coronavirus 2 infection who were supported by extracorporeal membrane oxygenation (ECMO) due to refractory hypoxemic respiratory failure. Methods: This observational, retrospective, and descriptive study reported a series of cases. Data were retrospectively collected from the medical records of patients who were admitted to the Pediatric Cardiologic Intensive Care of Hospital Dr. Carlos Alberto Studart Gomes and Hospital Regional da Unimed, between March 1, 2020, and June 30, 2021. Sociodemographic, clinical, and laboratory data were analyzed. Findings: The median age was 1.8 years (range: 0.4-14.5 years), 66.7% were males, and weight varied from 13 to 110 kg. The mean time between the onset of symptoms and cannulation, ECMO duration, and ventilation time were 15 days (range: 6-24 days)], 11 days (range: 6-19 days), and 20.5 days (range: 14-33 days), respectively. Five (83.3%) children were successfully decannulated and four survived with hospital discharge. One child died on ECMO support due to multiple organ dysfunction syndromes after 13 days and another one died 3 days after decannulation due to extensive hemorrhagic stroke. Our case series revealed a 33.3% in-hospital mortality rate. ECMO appears as a viable intervention in selected patients who failed conventional therapies in the pediatric population. Funding: This observational study received no funding.

Biomarkers of acute kidney injury in pediatric cardiac surgery.

Acute kidney injury (AKI) is characterized by a sudden decrease in kidney function. Children with congenital heart disease are a special group at risk of developing AKI. We performed a systematic review of the literature to search for studies reporting the usefulness of novel urine, serum, and plasma biomarkers in the diagnosis and progression of AKI and their association with clinical outcomes in children undergoing pediatric cardiac surgery. In thirty studies, we analyzed the capacity to predict AKI and poor outcomes of five biomarkers: Cystatin C, Neutrophil gelatinase-associated lipocalin, Interleukin-18, Kidney injury molecule-1, and Liver fatty acid-binding protein. In conclusion, we suggest the need for further meta-analyses with the availability of additional studies.

Perinatal unusual rhabdomyoma location - case report and systematic reviews of the literature.

Objective: To report a case of prenatal diagnosis of cardiac rhabdomyoma (CR) and neonatal surgical treatment as well as undertaking a systematic review of the literature to determine most frequent localization of CR, common signs and symptoms, associated pathologies, incidence of surgery, and prognoses for CR.Methods: We conducted systematic review of the literature on CR that were diagnosed and treated in the perinatal period, searching for English language articles in the PubMed/Medline database that were published within the past 20 years, using the following search terms: "cardiac rhabdomyoma"; "neonates"; "newborn"; "surgery".Results: Eighty-two studies were selected, but only 46 studies met the inclusion criteria. After birth, the majority of newborns were asymptomatic; however, murmurs and arrhythmia were also the two most prevalent signs of CR. The most prevalent location was the ventricles, corresponding to 40.3% of all cases, with 53% of these having a rhabdomyoma in the left ventricle. The incidence of multiple tumors was 56%, and in those cases the location of tumors was also most common in the ventricles. Tuberous sclerosis was the most commonly associated pathology, being present in 72% of cases of CR. Surgical treatment occurred in 27% of cases, and 3% of cases required surgery and prostaglandin. Regarding the perinatal outcome, 6% of cases resulted in fetal or neonatal death.Conclusion: CR are benign tumors which tend to spontaneously regress during early childhood but may have unfavorable outcomes in the presence of obstructive lesions and arrhythmias. Surgery is generally necessary in symptomatic patients.

Proposal of an Integrated Health Care Network System for Patients with Congenital Heart Defects.

The perspective of the integrated health system has a network of care with multiple integration dimensions among subsystems as nuclear representation, relating the clinical aspects and governance to the representations and collective values. The normative integration aims to ensure coherence between the system of representations and values of society simultaneously with the interfaces of clinical and functional integration. It builds a bridge with governance, which allows, through their skills, management of all system components, encouraging cooperation, communication and information, in order to ensure the population under their responsibility to access excellence services, exceeding their expectations. The integration of care consists of a durable coordination of clinical practices for those who suffer from health problems in order to ensure continuity and full range of the required professional services and organizations, coordinated in time and space, in accordance with the available knowledge. It is possible to establish the type of health equipment for each level of care for patients with congenital heart diseases. This strategy intends to offer timely care in appropriate moments and places, efficiently, operating cooperatively an interdependently, with ongoing exchange of its resources. Thus, situational integration establishes the system connection with the assessment environment that proposes to carry out value judgment, guided by an objective worldview, about an intervention or any of its components, in order to objectify the decision making.

Pulmonary artery banding: a simple procedure? A critical analysis at a tertiary center.

OBJECTIVE: Although pulmonary artery banding (PAB) seems to be a technically simple procedure it presents several peculiarities and is related to a significant morbidity and mortality. The aim of this study is to analyze the experience of a tertiary hospital on the PAB by assessing and correlating many aspects related to the procedure. METHODS: Between January 2000 and December 2008, 61 patients undergone PAB due to congenital heart disease with increased pulmonary blood flow at Messejana Heart Hospital were assessed as for mortality, complications, stay in mechanical ventilation and need for intensive care unit (ICU), use of vasoactive drugs, difficulties in the adjustment on the banding and reoperations. Some statistical analyzes were performed to compare the subgroups. RESULTS: In 46.8% of the patients the intended pressoric adjustment was not achieved and in 6.5% it was necessary another surgery to readjust the banding. The mean time of mechanical ventilation was 14.1+/-49.6 days and ICU 14.16+/-10.92 days. In 82.6% of the patients vasoactives drugs were administrated for 10.3+/-12.79 days. Severe complications were noted in 49.15% of patients and cardiac insufficiency was the most common one with an incidence of 44%. The mortality rate was 8.2% and it was not influenced by weight or associated procedures with the PAB neither if univentricular or biventricular heart disease. CONCLUSION: The PAB can be performed with acceptable mortality rates compatible with the ones of the world literature. Nevertheless, the adjustment of the banding is difficult to be assessed during the surgery by making the procedure complex and justifying the high incidence of complications and long stay in ICU. It wasn't found any specific risk factor significant to mortality neither uni- or biventricular heart disease.

Bandagem da artéria pulmonar: uma cirurgia simples? Uma análise crítica em um centro terciário / Pulmonary artery banding: a simple procedure? A critical analysis at a tertiary center

OBJETIVO: A bandagem da artéria pulmonar (BAP) é um procedimento tecnicamente simples, mas envolto em várias peculiaridades que o fazem apresentar elevadas taxas de morbidade e mortalidade. O objetivo deste estudo é analisar a experiência de um hospital de referência na bandagem da artéria pulmonar, avaliando e correlacionando diversas variáveis relacionadas ao procedimento. MÉTODOS: Entre janeiro de 2000 e dezembro de 2008, 61 pacientes submetidos a BAP por cardiopatia congênita de hiperfluxo no Hospital do Coração de Messejana-Fortaleza/CE foram avaliados quanto a mortalidade, complicações, permanência em ventilação mecânica (VM) e terapia intensiva (UTI), uso de drogas vasoativas, dificuldade de ajustes transoperatórios e reoperações para reajuste. Análise estatística foi realizada para comparações entre subgrupos. RESULTADOS: Em 46,8 por cento dos pacientes, não se conseguiu o ajuste pressórico pretendido e 6,5 por cento precisaram ser reoperados para reajustes. O tempo médio UTI e VM foi 14,16 ± 10,92 dias e 14,1 ± 49,6 dias, respectivamente. Em 82,6 por cento dos pacientes foram administradas drogas vasoativas por 10,30 ± 12,79 dias. Complicações graves incidiram em 49,15 por cento dos pacientes, com predominância da insuficiência cardíaca (44 por cento). A taxa de mortalidade foi de 8,2 por cento, não influenciada por peso, procedimentos associados ou cardiopatia univentricular ou biventricular. CONCLUSÃO: Neste estudo, a BAP foi realizada com taxas de mortalidade aceitáveis, compatíveis com a literatura mundial. No entanto, os ajustes transoperatórios são de difícil análise, tornando o procedimento complexo e justificando elevados índices de complicações, resultando em longa permanência em UTI. Nenhuma variável isolada representou significante fator de risco, dentre as quais, fisiologia uni ou biventricular
