RESUMEN
The efficacy and safety of rivaroxaban in patients with bioprosthetic mitral valves and atrial fibrillation or flutter remain uncertain. DESIGN: RIVER was an academic-led, multicenter, open-label, randomized, non-inferiority trial with blinded outcome adjudication that enrolled 1005 patients from 49 sites in Brazil. Patients with a bioprosthetic mitral valve and atrial fibrillation or flutter were randomly assigned (1:1) to rivaroxaban 20 mg once daily (15 mg in those with creatinine clearance <50 mL/min) or dose-adjusted warfarin (target international normalized ratio 2.0-30.); the follow-up period was 12 months. The primary outcome was a composite of all-cause mortality, stroke, transient ischemic attack, major bleeding, valve thrombosis, systemic embolism, or hospitalization for heart failure. Secondary outcomes included individual components of the primary composite outcome, bleeding events, and venous thromboembolism. SUMMARY: RIVER represents the largest trial specifically designed to assess the efficacy and safety of a direct oral anticoagulant in patients with bioprosthetic mitral valves and atrial fibrillation or flutter. The results of this trial can inform clinical practice and international guidelines.

BACKGROUND: 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) has emerged as a useful diagnostic tool for suspected infective endocarditis (IE) in patients with prosthetic valves or implantable devices. However, there is limited evidence regarding use of 18F-FDG-PET/CT for the diagnosis of native valve endocarditis (NVE). METHODS: Between 2014 and 2017, 303 episodes of left-sided suspected IE (188 prosthetic valves/ascending aortic prosthesis and 115 native valves) were studied. 18F-FDG-PET/CT accuracy was determined in the subgroups of patients with NVE and prosthetic valve endocarditis (PVE)/ascending aortic prosthesis infection (AAPI). Associations between inflammatory infiltrate patterns and 18F-FDG-PET/CT uptake were investigated in an exploratory ad hoc histological analysis. RESULTS: Among 188 patients with PVE/AAPI, the sensitivity, specificity, and positive and negative predictive values of 18F-FDG-PET/CT focal uptake were 93%, 90%, 89%, and 94%, respectively, while among 115 patients with NVE, the corresponding values were 22%, 100%, 100%, and 66%. The inclusion of abnormal 18F-FDG cardiac uptake as a major criterion at admission enabled a recategorization of 76% (47/62) of PVE/AAPI cases initially classified as "possible" to "definite" IE. In the histopathological analysis, a predominance of polymorphonuclear cell inflammatory infiltrate and a reduced extent of fibrosis were observed in the PVE group only. CONCLUSIONS: Use of 18F-FDG-PET/CT at the initial presentation of patients with suspected PVE increases the diagnostic capability of the modified Duke criteria. In patients who present with suspected NVE, the use of 18F-FDG-PET/CT is less accurate and could only be considered a complementary diagnostic tool for a specific population of patients with NVE.

Adenosine is an antiarrhythmic drug that slows conduction through the atrioventricular node and acts as a coronary blood vessel dilator. This case report highlights two unusual life-threatening events following the use of adenosine to revert supraventricular tachycardia in a structurally normal heart: non-sustained polymorphic ventricular tachycardia and myocardial infarction. A 46-year-old woman presented to the emergency department with a two-hour history of palpitations and was diagnosed with supraventricular tachycardia. Vagal maneuvers were ineffective, and after intravenous adenosine administration, the patient presented with chest pain and hypotension. The rhythm degenerated into non-sustained polymorphic ventricular tachycardia and spontaneously reverted to sinus rhythm with ST elevation in lead aVR and ST depression in the inferior and anterolateral leads. The patient spontaneously recovered within a few minutes. Despite successful arrhythmia reversal, the patient was admitted to the intensive care unit because of an infarction without obstructive atherosclerosis. This report aims to alert emergency physicians about the potential complications associated with supraventricular tachycardia and its reversal with adenosine.

BACKGROUND: As infective endocarditis has particular characteristics compared to other infectious diseases, it is not clear if sepsis scores are reported with good accuracy in these patients. The aim of this study is to evaluate the accuracy of the qSOFA and SOFA scores to predict mortality in patients with infective endocarditis. METHODS: Between January 2010 and June 2019, 867 patients with suspected left-sided endocarditis were evaluated; 517 were included with left-sided infective endocarditis defined as "possible" or "definite" endocarditis, according to the Modified Duke Criteria. ROC curves were constructed to assess the accuracy of qSOFA and SOFA sepsis scores for the prediction of in-hospital mortality. RESULTS: The median age was 57 years, 65% were male, 435 (84%) had pre-existing heart valve disease, and the overall mortality was 28%. The most frequent etiologies were Streptococcus spp. (36%), Enterococcus spp. (10%), and Staphylococcus aureus (9%). The sepsis scores from the ROC curves used to predict in-hospital mortality were qSOFA 0.601 (CI95% 0.522-0.681) and SOFA score 0.679 (CI95% 0.602-0.756). A sub-group analysis in patients with and without pre-existing valve disease for SOFA ≥ 2 showed ROC curves of 0.627 (CI95% 0.563-0.690) and 0.775 (CI95% 0.594-0.956), respectively. CONCLUSIONS: qSOFA and SOFA scores were associated with increased in-hospital mortality in patients with infective endocarditis. However, as accuracy was relatively lower compared to other sites of bacterial infections, we believe that this score may have lower accuracy when predicting the prognosis of patients with IE, because, in this disease, the patient's death may be more frequently linked to valvular and cardiac dysfunction, as well as embolic events, and less frequently directly associated with sepsis.
RESUMEN
BACKGROUND: Infective endocarditis continues to be a significant concern and may be undergoing an epidemiological transition. METHODS: Were studied 1804 consecutive episodes of infective endocarditis between 1978 and 2022. The mean age was 48 ( ± 19), and 1162 (64%) patients were male. Temporal trends in demographic data, comorbidities, predisposing conditions, microorganisms, complications and in-hospital death have been studied over the decades (1978-1988, 1989-1999, 2000-2010 and 2011-2022). The outcomes and clinical characteristics were modeled using nonlinear cubic spline functions. FINDINGS: Valve surgery was performed in 50% of the patients and overall in-hospital mortality was 30%. From the first to the fourth decade studied, the average age of patients increased from 29 to 57 years (p < 0.001), with significant declines in the occurrence of rheumatic valvular heart disease (15% to 6%; p < 0.001) and streptococcal infections (46% to 33%; p < 0.001). Healthcare-associated infections have increased (9% to 21%; p < 0.001), as have prosthetic valve endocarditis (26% to 53%; p < 0.001), coagulase-negative staphylococcal infections (4% to 11%; p < 0.001), and related-complications (heart failure, embolic events, and perivalvular abscess; p < 0.001). These changes were associated with a decline in adjusted in-hospital mortality from 34% to 25% (p = 0.019). INTERPRETATION: In the 44 years studied, there was an increase in the mean age of patients, healthcare-related, prosthetic valve, coagulase-negative staphylococci/MRSA infections, and related complications. Notably, these epidemiological changes were associated with a decline in the adjusted in-hospital mortality.

Chest pain is a frequent, potentially life-threatening condition in the emergency department and requires immediate investigation and treatment. This case report highlights a rare differential diagnosis of pleuritic chest pain: epipericardial fat necrosis. A 29-year-old man presented with normal clinical evaluation, electrocardiography, point-of-care ultrasound, and unremarkable laboratory tests. The initial hypothesis was acute pleuritis. Chest radiography revealed peri-cardiac nonspecific findings, and computed tomography revealed epicardial fat necrosis. Despite the rarity of this condition, accurate diagnosis allows for better practices. An algorithm for a diagnostic approach is proposed.

OBJECTIVE: This study aimed to describe the clinical characteristics of the pediatric population with COVID-19 in an Emergency Department (ED) of a Brazilian general hospital. METHODS: Epidemiological and clinical data of patients younger than 20 years old were collected from patients' medical records from February 2020 to July 2021. Most of the epidemiological data described pertains to hospitalized patients. We also reviewed coinfections, treatment, and outcomes and compared the first and second waves of COVID-19. RESULTS: We identified a total of 1303 episodes of SARS-CoV-2 infection. The median time from symptom onset to diagnosis was three days. Symptoms were present in 92.3% of the patients. The most common symptoms were fever (45.2%), nasal congestion/discharge (44.2%), and cough (39.4%). Chest radiography and tomography were performed in 7.7 and 3.3% of cases, with abnormal findings in 29.7 and 53.4%, respectively. Hospital admissions occurred in 3.5% of patients, mainly in the presence of comorbidities, in children under five years old and in those who presented to the ED during the first wave of COVID-19. Coinfection with a viral agent was identified in 20% of the 71 cases tested in this study, and a positive rapid test for Streptococcus pyogenes was found in 8% of the 174 cases tested, with no impact of these coinfections on hospitalization. CONCLUSIONS: We found that COVID-19 was a mild disease in most children in our study population, with most hospitalizations and readmissions occurring during the first wave of COVID-19.

Valvular heart disease (VHD) is an increasing health problem worldwide. Patients with VHD may experience several cardiovascular-related emergencies. The management of these patients is a challenge in the emergency department, especially when the previous heart condition is unknown. Specific recommendations for the initial management are currently poor. This integrative review proposes an evidence-based three-step approach from bedside VHD suspicion to the initial treatment of the emergencies. The first step is the suspicion of underlying valvular condition based on signs and symptoms. The second step comprises the attempt to confirm the diagnosis and assessment of VHD severity with complementary tests. Finally, the third step addresses the diagnosis and treatment options for heart failure, atrial fibrillation, valvular thrombosis, acute rheumatic fever, and infective endocarditis. In addition, several images of complementary tests and summary tables are provided for physician support.
A doença valvar cardíaca é um problema de saúde crescente no mundo. Os pacientes com valvopatia podem apresentar diversas emergências cardiovasculares. O manejo desses pacientes é um desafio no departamento de emergência, principalmente quando a condição cardíaca prévia é desconhecida. Atualmente, recomendações específicas para o manejo inicial são limitadas. A presente revisão integrativa propõe uma abordagem baseada em evidência, de três etapas, desde a suspeita de valvopatia à beira do leito até o tratamento inicial das emergências. A primeira etapa é a suspeita de uma condição valvar subjacente com base nos sinais e sintomas. A segunda etapa consiste na tentativa de confirmação diagnóstica e avaliação da gravidade da valvopatia com exames complementares. Finalmente, a terceira etapa aborda as opções diagnósticas e terapêuticas para insuficiência cardíaca, fibrilação atrial, trombose valvar, febre reumática aguda, e endocardite infecciosa. Além disso, apresentamos imagens de exames complementares e tabelas para apoio aos médicos.

Cyanosis is typically a sign of a potentially life-threatening condition in the emergency department and requires immediate workup and treatment. This case report highlights the diagnostic reasoning and clinical approach to cocaine- and volatile nitrite-induced methemoglobinemia (MHG). MHG is a rare, life-threatening cause of cyanosis. The diagnosis must be suspected in the emergency department in the presence of hypoxia and cyanosis disproportionate to cardiopulmonary repercussions and refractory to oxygen supplementation. Acquired causes are more prevalent than genetics, and recreational drugs should be highly suspected. Despite the rarity of this situation, cyanosis precipitants and the specificities of each hemoglobinopathy are reviewed in this article.
RESUMEN
BACKGROUND: Heyde's syndrome is the association of severe aortic stenosis with episodes of gastrointestinal bleeding due to angiodysplastic lesion. Little is known about the factors associated with new episodes of bleeding and long-term outcomes. Furthermore, most data are restricted to case reports and small case series. OBJECTIVE: To assess the clinical, laboratory and echocardiography profile of patients with Heyde's syndrome who underwent valve intervention or drug therapy. METHODS: Prospective cohort of 24 consecutive patients from 2005 to 2018. Clinical, laboratory and echocardiography data were assessed, as well as those related to valve intervention and outcomes after diagnosis. A P <0.05 was used to indicate statistical significance. RESULTS: Half of the 24 patients presented with bleeding requiring blood transfusion on admission. Angiodysplasias were more frequently found in the ascending colon (62%). Valve intervention (surgical or transcatheter) was performed in 70.8% of the patients, and 29.2% remained on drug therapy. News episodes of bleeding occurred in 25% of the cases, and there was no difference between clinical and intervention groups (28.6 vs 23.5%, p = 1.00; respectively). Mortality at 2-year and 5-year was 16% and 25%, with no difference between the groups (log-rank p = 0.185 and 0.737, respectively). CONCLUSIONS: Patients with Heyde's syndrome had a high rate of bleeding requiring blood transfusion on admission, suggesting that it is a severe disease with high mortality risk. No difference was found between clinical and intervention group regarding the rate of rebleeding and late mortality.
FUNDAMENTOS: A síndrome de Heyde é a associação de estenose aórtica importante com episódio de sangramento gastrointestinal por lesões angiodisplásicas. Pouco é conhecido sobre os fatores associados a novos sangramentos e desfechos em longo prazo. Além disso, a maioria dos dados é restrita a relatos de casos e pequenas séries. OBJETIVO: Avaliar o perfil clínico, laboratorial e ecocardiográfico de pacientes com síndrome de Heyde submetidos a intervenção valvar ou tratamento medicamentoso. MÉTODOS: Coorte prospectiva de 24 pacientes consecutivos entre 2005 e 2018. Foram avaliados dados clínicos, laboratoriais, ecocardiográficos e relacionados à intervenção valvar e a desfechos após o diagnóstico. Valor de p<0,05 foi considerado estatisticamente significante. RESULTADOS: Metade dos 24 pacientes apresentou sangramento com necessidade de transfusão sanguínea na admissão. Angiodisplasias foram encontradas mais frequentemente no cólon ascendente (62%). Intervenção valvar (cirúrgica ou transcateter) foi realizada em 70,8% dos pacientes, e 29,2% foram mantidos em tratamento clínico. Novos episódios de sangramento ocorreram em 25% dos casos, e não houve diferença entre os grupos clínico e intervenção (28,6 vs. 23,5%, p=1,00; respectivamente). A mortalidade no seguimento de 2 e 5 anos foi de 16% e 25%, sem diferença entre os grupos (log-rank p = 0,185 e 0,737, respectivamente). CONCLUSÕES: Pacientes com síndrome de Heyde tiveram alta taxa de sangramento com necessidade de transfusão sanguínea na admissão, sugerindo ser uma doença grave e com risco elevado de mortalidade. Não encontramos diferenças entre os grupos submetidos ao tratamento clínico e à intervenção valvar em relação a taxas de ressangramento e mortalidade tardia.

BACKGROUND: Evidence regarding biomarkers for risk prediction in patients with infective endocarditis (IE) is limited. We aimed to investigate the value of a panel of biomarkers for the prediction of in-hospital mortality in patients with IE. METHODS: Between 2016 and 2018, consecutive IE patients admitted to the emergency department were prospectively included. Blood concentrations of nine biomarkers were measured at admission (D0) and on the seventh day (D7) of antibiotic therapy: C-reactive protein (CRP), sensitive troponin I (s-cTnI), procalcitonin, B-type natriuretic peptide (BNP), neutrophil gelatinase-associated lipocalin (NGAL), interleukin 6 (IL6), tumor necrosis factor α (TNF-α), proadrenomedullin, alpha-1-acid glycoprotein, and galectin 3. The primary endpoint was in-hospital mortality. RESULTS: Among 97 patients, 56% underwent cardiac surgery, and in-hospital mortality was 27%. At admission, six biomarkers were independent predictors of in-hospital mortality: s-cTnI (OR 3.4; 95%CI 1.8-6.4; P<0.001), BNP (OR 2.7; 95%CI 1.4-5.1; P=0.002), IL-6 (OR 2.06; 95%CI 1.3-3.7; P=0.019), procalcitonin (OR 1.9; 95%CI 1.1-3.2; P=0.018), TNF-α (OR 1.8; 95%CI 1.1-2.9; P=0.019), and CRP (OR 1.8; 95%CI 1.0-3.3; P=0.037). At admission, S-cTnI provided the highest accuracy for predicting mortality (area under the ROC curve: s-cTnI 0.812, BNP 0.727, IL-6 0.734, procalcitonin 0.684, TNF-α 0.675, CRP 0.670). After 7 days of antibiotic therapy, BNP and inflammatory biomarkers improved their performance (s-cTnI 0.814, BNP 0.823, IL-6 0.695, procalcitonin 0.802, TNF-α 0.554, CRP 0.759). CONCLUSION: S-cTnI concentration measured at admission had the highest accuracy for mortality prediction in patients with IE.

RESUMEN
INTRODUCTION: the EuroSCORE II and STS are the most used scores for surgical risk stratification and indication of transcatheter aortic valve implantation (TAVI). However, its role as a tool for mortality prediction in patients undergoing TAVI is still unclear. OBJECTIVE: to evaluate the performance of the EuroSCORE II and STS as predictors of in-hospital and 30-day mortality in patients undergoing TAVI. METHODS: we included 59 symptomatic patients with severe aortic stenosis that underwent TAVI between 2010 and 2014. The variables were analyzed using Student's t-test and Fisher's exact test and the discriminative power was evaluated using receiver operating characteristic curve (ROC) and area under the curve (AUC) with a 95% confidence interval. RESULTS: mean age was 81±7.3 years, 42.3% men. The mean EuroSCORE II was 7.6±7.3 % and STS was 20.7±10.3%. Transfemoral procedure was performed in 88.13%, transapical in 3.38% and transaortic in 8.47%. In-hospital mortality was 10.1% and 30-day mortality was 13.5%. Patients who died had EuroSCORE II and STS higher than the survivors (33.7±16.7vs. 18.6±7.3% p=0,0001 for STS and 13.9±16.1 vs. 4.8±3.8% p=0.0007 for EuroSCORE II). The STS showed an AUC of 0.81 and the EuroSCORE II of 0.77 and there were no differences in the discrimination ability using ROC curves (p=0.72). CONCLUSION: in this cohort, the STS and EuroSCORE II were predictors of in-hospital and 30-days mortality in patients with severe aortic stenosis undergoing TAVI.

A mortalidade no seguimento de 2 e 5 anos foi de 16% e 25%, sem diferença entre os grupos (log-rank p = 0,185 e 0,737, respectivamente). Conclusões Pacientes com síndrome de Heyde tiveram alta taxa de sangramento com necessidade de transfusão sanguínea na admissão, sugerindo ser uma doença grave e com risco elevado de mortalidade. Não encontramos diferenças entre os grupos submetidos ao tratamento clínico e à intervenção valvar em relação a taxas de ressangramento e mortalidade tardia.
Abstract Background Heyde's syndrome is the association of severe aortic stenosis with episodes of gastrointestinal bleeding due to angiodysplastic lesion. Little is known about the factors associated with new episodes of bleeding and long-term outcomes. Furthermore, most data are restricted to case reports and small case series. Objective To assess the clinical, laboratory and echocardiography profile of patients with Heyde's syndrome who underwent valve intervention or drug therapy. Methods Prospective cohort of 24 consecutive patients from 2005 to 2018. Clinical, laboratory and echocardiography data were assessed, as well as those related to valve intervention and outcomes after diagnosis. A P <0.05 was used to indicate statistical significance. Results Half of the 24 patients presented with bleeding requiring blood transfusion on admission. Angiodysplasias were more frequently found in the ascending colon (62%). Valve intervention (surgical or transcatheter) was performed in 70.8% of the patients, and 29.2% remained on drug therapy. News episodes of bleeding occurred in 25% of the cases, and there was no difference between clinical and intervention groups (28.6 vs 23.5%, p = 1.00; respectively). Mortality at 2-year and 5-year was 16% and 25%, with no difference between the groups (log-rank p = 0.185 and 0.737, respectively). Conclusions Patients with Heyde's syndrome had a high rate of bleeding requiring blood transfusion on admission, suggesting that it is a severe disease with high mortality risk. No difference was found between clinical and intervention group regarding the rate of rebleeding and late mortality.
