Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

ABSTRACT Purpose: Vasoplegia, or vasoplegic shock, is a syndrome whose main characteristic is reducing blood pressure in the presence of a standard or high cardiac output. For the treatment, vasopressors are recommended, and the most used is norepinephrine. However, new drugs have been evaluated, and conflicting results exist in the literature. Methods: This is a systematic review of the literature with meta-analysis, written according to the recommendations of the PRISMA report. The SCOPUS, PubMed, and ScienceDirect databases were used to select the scientific articles included in the study. Searches were conducted in December 2022 using the terms “vasopressin,” “norepinephrine,” “vasoplegic shock,” “postoperative,” and “surgery.” Meta-analysis was performed using Review Manager (RevMan) 5.4. The endpoint associated with the study was efficiency in treating vasoplegic shock and reduced risk of death. Results: In total, 2,090 articles were retrieved; after applying the inclusion and exclusion criteria, ten studies were selected to compose the present review. We found no significant difference when assessing the outcome mortality comparing vasopressin versus norepinephrine (odds ratio = 1.60; confidence interval 0.47–5.50), nor when comparing studies on vasopressin versus placebo. When we analyzed the length of hospital stay compared to the use of vasopressin and norepinephrine, we identified a shorter length of hospital stay in cases that used vasopressin; however, the meta-analysis did not demonstrate statistical significance. Conclusions: Considering the outcomes included in our study, it is worth noting that most studies showed that using vasopressin was safe and can be considered in managing postoperative vasoplegic shock.

Abstract Background: Elderly patients may present with visual function impairment after surgery, which may increase the incidence of postoperative delirium and falls and decrease their quality of life. The aim of this study was to assess visual function in elderly patients after long-duration nonocular surgery to determine the incidence and risk factors for visual function impairment after surgery. Methods: This prospective and observational study included patients aged between 60 and 80 years who had been scheduled for elective non-ocular surgery expected to last longer than 120 minutes under general anaesthesia. Ocular examinations were performed before surgery, on post-operative day 3 and on post-operative day 21 and consisted of a LogMAR-Snellen chart test, a Jager chart test, biomicroscopy, optical tonometry, ocular motility assessment and fundoscopy. Baseline characteristics of all patients as well as intraoperative and postoperative data were collected. Results: A total of 107 patients were included in the final analysis. Visual function impairment was diagnosed in 21 patients (19.6%) at POD 3. Of those, 7 patients (6.5%) still presented with visual changes at POD 21. On POD 3, compared with that at baseline, visual acuity assessed by the Snellen chart test had decreased in these patients. Significant differences regarding refraction tests and intraocular pressure measures were also found. Multivariable analysis identified diabetes mellitus, duration of surgery, hypotension during anaesthesia induction, lower peripheral oxygen saturation at the end of the procedure and body mass index as independent risk factors for postoperative visual impairment. Conclusion: In elderly patients undergoing long-duration non-ocular procedures under general anaesthesia, the incidence of visual function impairment was considerably high. Most patients recovered to baseline visual function, but clinically significant visual changes may still be present 3 weeks after surgery. Obesity, diabetes mellitus, and the duration of surgical and anaesthetic techniques appear to increase the risk of visual impairment after surgery.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII) são afecções inflamatórias crônicas de caráter recorrente, cujas taxas de incidência e prevalência têm aumentado, inclusive no Brasil. A longo prazo, são responsáveis por danos estruturais que impactam na qualidade de vida, morbidade e mortalidade dos pacientes. OBJETIVO: Avaliar o perfil dos médicos que atendem pacientes com DII, assim como as características deste atendimento, demandas não atendidas e dificuldades. MÉTODOS: Um questionário contendo 17 variáveis foi elaborado e enviado para médicos, selecionados a partir do cadastro da Comissão das Estaduais do Grupo de Estudos da Doença Inflamatória Intestinal do Brasil (GEDIIB), totalizando 286 médicos de 101 cidades brasileiras distribuídas por 21 estados e Distrito Federal. RESULTADOS: A maioria dos médicos que respondeu o questionário foram Gastroenterologistas e Coloproctologistas. Mais de 60% tinham até 20 anos de atuação na especialidade e 53,14% trabalhavam em três locais ou mais. A dificuldade no acesso ou liberação de medicamentos ficou evidenciada neste questionário, assim como a dificuldade no encaminhamento para profissionais não médicos que atuam em DII. Mais de 75% dos médicos relataram dificuldades para realização de enteroscopia por duplo balão e cápsula endoscópica, e 67,8% para realização da calprotectina. Em relação ao número de pacientes atendidos por cada médico, foi evidenciado que não há uma concentração de pacientes sob a responsabilidade de poucos médicos. O infliximabe e o adalimumabe foram os biológicos mais utilizados e ficou evidenciada prescrição maior de derivados de 5-ASA para retocolite ulcerativa quando comparada à doença de Crohn. Os corticoides foram prescritos para uma parcela menor de pacientes em ambas doenças. Os temas “falha a terapia biológica” e “novas drogas” foram referidos como aqueles com maior prioridade para discussão em eventos científicos. Em relação às possíveis diferenças entre cada região e o restante do país, os médicos da região Norte relataram maior dificuldade no acesso a exames complementares e os médicos da região Nordeste, maior dificuldade no acesso ou liberação de medicamentos. CONCLUSÃO: Os dados obtidos por meio deste estudo mostram o perfil do atendimento médico especializado em DII e podem se constituir em ferramenta útil para para elaboração de políticas governamentais e para sociedade brasileira como um todo.

ABSTRACT BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the “Study Group of Inflammatory Bowel Disease of Brazil” (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn’s disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics “biological therapy failure” and “new drugs” were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country’s regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

Resumo A distribuição das espécies de Lucifer Thompson, 1829 (Decapoda: Luciferidae) no Giro Subtropical do Atlântico Sul foi avaliada pela Comissão Transatlântico Brasil I, entre novembro e dezembro de 2009. As amostras foram coletadas em 83 estações, em dois perfis entre o Brasil e África (20º e 30º Sul). Foram realizados arrastos oblíquos com rede cilindro-cônica, até 150 metros de profundidade. Observou-se uma relação sexual distinta entre as duas espécies encontradas. L. faxoni apresentou número de fêmeas significativamente maior em relação aos machos: 1:0.5 (X2 = 21,77, p = 0,0001), enquanto L. typus, teve proporção sexual de machos significativamente maior que de fêmeas: 1.86:1 (X2 = 50,84, p = 0,0001). A distribuição de L. typus variou entre as porções oeste e leste da cordilheira Mesoceânica. Essa distribuição esteve relacionada significativamente com a salinidade (R2 = 0.13; F(3.79); p = 0,009), mais elevada à oeste da área de estudo. No presente trabalho as duas espécies tiveram seus registros ampliados para o Giro Subtropical do Atlântico. De forma geral, os camarões luciferídeos foram mais frequentes e abundantes nas estações de coleta a oeste da Cordilheira Mesoceância, com L. typus sendo mais representativo tanto em abundância quanto em ocorrência.

Abstract The distribution of the species of Lucifer Thompson, 1829 (Decapoda: Luciferidae) in the South Atlantic Subtropical Gyre was assessed by the Brazil Transatlantic Commission in November and December 2009. The samples were collected at 83 stations on two profiles between Brazil and Africa (20 º and 30 ºS). Oblique hauls were performed with a WP-2 net up to 150 meters deep. A distinct sexual relationship was noted between the two species found and L. faxoni presented a significantly higher number of females relative to males 1:0.5 (X2 = 21.77, p = 0.0001). The L. typus sex ratio had significantly more males than females 1.86:1 (X2=50.84, p = 0.0001). The distribution of L. typus occurred in both the western and the eastern portions of the Mid-Oceanic Ridge. This distribution was significantly related to salinity (R2 = 0:13; F = 3.79, p = 0.009), which was higher in the western portion of the study area. In addition, the recordings of the two species were extended to the Atlantic Subtropical Gyre. Overall, Luciferidae shrimp were more common and abundant at the stations west of the Mid-Oceanic Ridge and L. typus was the most frequent and abundant species.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Introdução: Os stents farmacológicos eluidores de everolimus com polímero durável e de biolimus A9 com polímero bioabsorvível foram concebidos para minimizar a resposta inflamatória local e propiciar melhor cobertura endotelial das hastes. Nesta análise, objetivamos apresentar os resultados do ultrassom intracoronário de 6 meses da comparação desses dispositivos como desfecho secundário do estudo BIOACTIVE. Métodos: O BIOACTIVE foi um estudo multicêntrico, randomizado (1:1), que teve como objetivo primário comparar a função endotelial coronária e o porcentual de cobertura das hastes dos stents BioMatrix® e Xience V®, por meio da tomografia de coerência óptica. Foram incluídos pacientes com lesão única, de novo, em coronárias, entre 3,0 e 3,5 mm e com extensão até 20 mm. Foram excluídos pacientes diabéticos ou na fase aguda de infarto agudo do miocárdio com supradesnivelamento de ST, lesões ostiais, em bifurcações ou com trombo. Resultados: O ultrassom intracoronário foi realizado em 35 (87,5%) dos 40 pacientes incluídos, sendo 21 pacientes com BioMatrix® e 14 com Xience V®. Os volumes do vaso (339,8 ± 149,4 mm3 vs. 343,0 ± 118,6 mm3; p = 0,95) e do stent (174,9 ± 73,6 mm3 vs. 166,2 ± 53,6mm3; p = 0,70) não mostraram diferenças, bem como o volume de hiperplasia (3,7 ± 2,6 mm3 vs. 4,5 ± 5,9 mm3; p = 0,57) e o porcentual de obstrução intimal intra-stent (2,3 ± 2,0% vs. 2,4 ± 2,8%; p = 0,90). Conclusões: Nesta comparação randomizada, ambos os stents mostraram-se efetivos em suprimir a resposta neointimal no médio prazo, e não mostraram sinais indiretos de toxicidade local.

A escolha de épocas de semeadura adequadas pode maximizar o aproveitamento da interação genótipo x ambiente e incrementar a produtividade de grãos e a qualidade industrial de trigo (Triticum aestivum L.). Objetivou-se com o estudo identificar épocas de semeadura adequadas que maximizam a produtividade de grãos e a qualidade industrial de cultivares de trigo. Sete cultivares de trigo (BRS 179, BRS Guamirim, BRS Guabiju, BRS Umbu, Safira, CD 105 e CD 115) foram avaliadas em quatro épocas de semeadura (01 e 15 de junho, 01 e 15 de julho) durante duas safras agrícolas (2007 e 2008). Utilizou-se delineamento em blocos ao acaso com quatro repetições. Somados, os efeitos de ano e épocas de semeadura explicaram 93% da variância para produtividade de grãos. Em 2007, as cultivares CD 105 e Safira apresentaram a maior produtividade de grãos (GY) em todas as épocas de semeadura. Apenas as cultivares BRS Guabiju e Safira apresentaram elevada qualidade de panificação em qualquer época de semeadura avaliada. Em 2008, as condições ambientais foram favoráveis ao aumento da GY, contudo de menor qualidade industrial. É possível maximizar a GY e a qualidade industrial do trigo com a escolha de cultivares adaptadas e épocas de semeadura mais adequadas.

Choosing the right sowing dates can maximize the outcomes of the interaction between genotype and environment, thus increasing grain yield and baking quality of wheat (Triticum aestivum L.). The present study aimed at determining the most appropriate sowing dates that maximize grain yield and baking quality of wheat cultivars. Seven wheat cultivars (BRS 179, BRS Guamirim, BRS Guabiju, BRS Umbu, Safira, CD 105 and CD 115) were evaluated at four sowing dates (the 1st and the 15th of June and July) in two harvesting seasons (2007 and 2008). The study was setup in a completely randomized block design with four repetitions. The effects of the year and sowing date when combined explained 93% of the grain yield variance. In 2007, the CD 105 and Safira cultivars had the highest grain yield (GY) for all sowing dates. Only the BRS Guabiju and Safira cultivars possessed high baking quality for all sowing dates assessed. In 2008, the environmental conditions were favorable for superior GY, but the baking quality was inferior. Considering adapted cultivars and sowing dates, it is possible to maximize grain yield and baking quality of wheat.

O objetivo deste trabalho foi avaliar a ciclagem de nutrientes por plantas de cobertura e a sua influência sobre o desempenho da rotação entre arroz de terras altas e soja. As culturas foram implantadas sob plantio direto, em Latossolo Vermelho distroférrico, na região do Cerrado de Goiás. As plantas de cobertura foram semeadas mecanicamente, também em plantio direto, após a colheita da soja (25/3/2008) e do arroz (7/4/2009). Utilizou-se o delineamento de blocos ao acaso, com parcelas subdivididas no tempo e quatro repetições. Os tratamentos consistiram das seguintes espécies de plantas de cobertura, além do pousio: Urochloa ruziziensis, U. brizantha, Pennisetum glaucum e U. ruziziensis + Cajanus cajan. A avaliação dos nutrientes remanescentes na palhada foi feita aos: 0, 15, 30, 60, 90 e 120 dias a partir da data da dessecação das plantas de cobertura. Urochloa ruziziensis e U. brizantha apresentaram maior eficiência no acúmulo e na liberação de nutrientes, principalmente quanto ao potássio. Urochloa ruziziensis é a espécie mais indicada como planta de cobertura antecessora à cultura do arroz de terras altas, em plantio direto. No entanto, nenhuma espécie de cobertura afeta significativamente a produtividade de grãos da soja.

The objective of this work was to evaluate nutrient cycling by cover crops and its influence on the performance of the rotation between upland rice and soybean. The crops were sown under no-tillage, in a Rhodic Haplustox, in the Cerrado region of the state of Goiás, Brazil. The cover crops were sown mechanically, also under no-tillage, after the harvest of soybean (3/25/2008) and rice (4/7/2009). A randomized complete block design was used, split-plotted in time, with four replicates. The treatments consisted of the following cover crop species, besides fallow: Urochloa ruziziensis, U. brizantha, Pennisetum glaucum and U. ruziziensis + Cajanus cajan. The evaluation of the remaining nutrient in straw was performed at 0, 15, 30, 60, 90, and 120 days from the desiccation date of the cover crops. Urochloa ruziziensis and U. brizantha were the most efficient in the accumulation and release of nutrients, especially potassium. Urochloa ruziziensis is the most suited species for use as a cover crop previous to upland rice cultivation under no-tillage. However, none of the cover crop species significantly affect soybean grain yield.

A difusão do uso da tecnologia do resfriamento, como estratégia para manutenção das características microbiológicas e organolépticas do leite, não associada aos cuidados básicos de higiene na obtenção do produto, fez com que os micro-organismos psicrotróficos emergissem como as principais bactérias deteriorantes da indústria láctea. Este estudo teve por objetivo avaliar como o metabolismo psicrotrófico proteolítico responde a diferentes temperaturas de incubação do leite, delineando um paralelo entre multiplicação de psicrotróficos, quantidade de micro-organismos com capacidade de hidrolisar proteínas e quantidade de GMP (glicomacropeptídeo) liberada. As amostras de leite, coletadas diretamente do tanque de resfriamento, foram submetidas à contagem de micro-organismos psicrotróficos, contagem de micro-organismos proteolíticos e determinação da concentração de GMP, em diferentes tempos (12 h; 24 h; 48 h) e temperaturas (4°C; 8°C; 12°C) de armazenamento. Não houve linearidade entre os parâmetros microbiológicos e o GMP aferido, segundo o binômio tempo/temperatura. A maior concentração de GMP (5,07 µg/mL) foi aferida no binômio 8°C/24 h (T8/M24). Esses dados indicam a necessidade de estudos sobre o metabolismo da microbiota psicrotrófica, de forma a elucidar questões básicas e de profunda relevância sobre seu metabolismo.

The widespread use of cooling technology as a tool for maintaining the microbiological and organoleptic characteristics of milk, Without effective hygienic practices throughout the milk production, caused the psychrotrophic micro-organisms to become major deteriorative bacteria in the dairy industry. The present study aimed to assess how the proteolytic psychrotrophic metabolism responds to different milk storage temperatures, drawing a parallel among psychrotrophic growth, amount of micro-organisms capable of breaking down proteins and amount of GMP (glycomacropeptide) released. Milk samples were collected directly from the cooling tank and subjected to count of psychrotrophs, count of proteolytic micro-organisms and the concentration of GMP at different storage times and temperatures. There was no linearity between the microbiological parameters and the GMP measured, according to the time/temperature binomial. The highest concentration of GMP (5.07 mg/mL) was measured in the binomial 8°C/24h (T8/M24). The data make clear the need for further studies about questions involving the psychrotrophic microbiota in order to clarify extremely important basic questions about their metabolism.

FUNDAMENTO: Avanço dos métodos não invasivos de imagem proporcionou o aumento no número de diagnóstico de tumores cardíacos. Apesar disso, a literatura apresenta poucos trabalhos envolvendo tumores cardíacos primários em crianças. OBJETIVO: Avaliar retrospectivamente casos de tumores cardíacos primários em crianças, considerando manifestações clínicas iniciais, exames utilizados para o diagnóstico, indicação cirúrgica, tipos histopatológicos encontrados e evolução pós-operatória imediata. MÉTODOS: O estudo foi retrospectivo, baseado na avaliação de prontuários no período de 1983 a 2011. Incluímos somente casos que foram orientados para tratamento cirúrgico no período. Avaliaram-se a idade na admissão, o diagnóstico pré-natal, a história familial, os sintomas iniciais e os resultados de exames realizados. Foram coletados, ainda, a data e indicação de cirurgia, os achados intraoperatórios, o resultado do exame histopatológico, assim como as complicações imediatas no pós-operatório. RESULTADOS: Dos 18 pacientes estudados, as manifestações clínicas mais encontradas foram dispneia e sopro cardíaco (7 e 6 pacientes, respectivamente); o método de complemento diagnóstico mais usado foi o ecocardiograma (18 pacientes); a obstrução cavitária ou do trato de entrada ou saída ventricular foi a principal indicação de cirurgia (12 casos); o perfil histológico mais encontrado foi rabdomioma (7 pacientes); a maioria dos pacientes apresentou boa evolução clínica. CONCLUSÃO: Neste estudo o diagnóstico por imagem foi basicamente ecocardiográfico, com boa correlação com os achados intraoperatórios. Os achados histopatológicos foram concordantes com a literatura, com o rabdomioma apresentando-se como o tumor mais comum em crianças. A evolução após tratamento cirúrgico mostrou-se favorável na maior parte dos casos.

BACKGROUND: The advancement of noninvasive imaging methods has resulted in the increase in diagnosis of heart neoplasms. However, the literature has few studies involving primary cardiac neoplasms in children. OBJECTIVE: To retrospectively review cases of primary heart neoplasms in children, considering the initial clinical manifestations, diagnostic tests used, surgical indication, histopathological types and immediate postoperative course. METHODS: The retrospective study was based on the assessment of medical records from 1983 to 2011. Only cases that were referred for surgical treatment during that period were included. Age at admission, prenatal diagnosis, family history, initial symptoms and the results of performed tests were assessed. Moreover, the date and indication of the surgery, intraoperative findings, the result of the histopathological analysis, as well as the immediate postoperative complications were recorded. RESULTS: Of the 18 patients studied, the most frequent clinical manifestations were dyspnea and heart murmur (7 and 6 patients, respectively); the most often used adjunct diagnostic method was echocardiography (18 patients); cavitary obstruction or ventricular inflow or outflow tract obstruction was the main indication for surgery (12 cases); the most common histological profile was rhabdomyoma (7 patients) and most patients showed good clinical outcome. CONCLUSIONS: In this study, imaging diagnosis was basically attained through echocardiography, with good correlation with intraoperative findings. Histopathological findings were consistent with the literature, with rhabdomyoma being the most common neoplasm in children. The evolution after surgical treatment was favorable in most cases.
