RESUMEN
Background: Bleeding is a serious cause of hypotension and tachycardia after childbirth and should always be considered. Case presentation: A healthy woman in her thirties who had previously undergone caesarean section, underwent induction and operative vaginal delivery. Postpartum, she experienced chest pain, hypotension and tachycardia, and had signs of ischaemia on electrocardiogram. A CT scan showed a large intraperitoneal haematoma. The patient underwent immediate laparotomy and received a massive blood transfusion. However, no large haematoma was found. The chest pain was attributed to a myocardial infarction caused by hypovolaemic shock. After discharge, the patient experienced significant vaginal bleeding and was transferred to a different university hospital. A CT scan revealed a large retroperitoneal haematoma. Emergency surgery was performed based on the suspicion of active bleeding, but only an older haematoma was found. Re-evaluation of the initial CT scan revealed that the haematoma was in fact located retroperitoneally and was thereby not found in the first operation. Interpretation: This case highlights the importance of bleeding as an important cause in unstable postpartum patients. Additionally, it is a reminder that retroperitoneal haematomas can occur in obstetric patients and can mask typical symptoms of uterine rupture such as abdominal pain. also hindering perioperative diagnosis.

BACKGROUND: Physicians often focus on possible cardiac causes in patients presenting with chest pain. However, this case highlights a patient who presented with chest pain caused by ingestion of a foreign body after an uneventful meal eaten an hour prior to presentation. The fishbone was discovered after imaging. The article aims to raise awareness regarding the potential origins of chest pain, highlighting that it may stem from non-cardiac conditions. METHODS: The methodology employed in this study involved conducting a case study that meticulously examined the repercussions and management strategies associated with foreign body ingestion. RESULTS: The case report delineates the scenario of a 27-year-old male patient who inadvertently ingested a fishbone during a routine meal. It details the swift decline in clinical status, the meticulous diagnostic procedures employed, the subsequent management strategies implemented and the ultimate discharge of the patient in a stable condition. CONCLUSION: This case highlights the importance of comprehensive history taking and considering a wide range of causes of chest pain when evaluating a patient. The foreign body ingested with the resulting cardiac complications could have been fatal if not promptly diagnosed.Contribution: This study contributed to advancing awareness surrounding foreign body ingestion, shedding light on potential complications and offering valuable insights into effective management strategies.

Mediastinal mature cystic teratomas are rare benign germ cell tumors that predominantly affect children. Despite their low incidence, they present unique diagnostic and management challenges. Early recognition and appropriate surgical intervention are crucial for optimal outcomes. This case report aims to highlight the importance of prompt diagnosis and management of mediastinal mature cystic teratomas in pediatric patients. We present the case of a 10-year-old female patient who presented with persistent chest pain and dyspnea. Imaging studies, including a chest X-ray and contrast-enhanced chest CT scan, revealed a large, well-circumscribed anterior mediastinal mass with calcifications. The patient underwent a right thoracotomy, resulting in the excision of a 6 × 5 × 5 cm mature cystic teratoma. Histopathological examination confirmed the diagnosis. The patient had an uneventful recovery and was discharged in stable condition. Mediastinal mature cystic teratomas pose diagnostic challenges due to their nonspecific symptoms and heterogeneous imaging characteristics. Differential diagnosis includes other mediastinal masses containing fat and calcifications. Surgical excision is the preferred treatment, although complete removal can be challenging due to adhesions to neighboring structures. Close follow-up is necessary to monitor for recurrence and complications. Mediastinal mature cystic teratomas are rare tumors with variable clinical presentations. Early detection and surgical intervention are crucial for optimal outcomes. These tumors should be included in the list of differential diagnoses for mediastinal masses in pediatric patients.

Takayasu's arteritis-pulmonary artery involvement (TA-PAI) is a chronic, progressive, inflammatory disease affecting the pulmonary artery and its branches. Patients typically present with non-specific respiratory symptoms, such as fever, dyspnea, and chest pain, leading to a high rate of misdiagnosis. The diagnosis of TA-PAI is currently based on the diagnostic criteria of aortitis and imaging evidence of pulmonary artery involvement. However, pulmonary artery involvement is not typically included in the diagnostic criteria for aortitis, which may lead to a significant underestimation of the diagnostic rate of TA-PAI, particularly in cases where pulmonary artery involvement is the only manifestation. This article reports the case of a 26-year-old female patient who presented with recurrent chest pain and fever. She was initially diagnosed with pneumonia in a foreign hospital but did not show significant improvement after four months of treatment. Eventually, she was diagnosed with pulmonary artery involvement in aortitis and was stabilized with hormones, immunosuppressive drugs, and pulmonary vascular intervention. By analyzing the clinical features and diagnostic and therapeutic approaches of this case, and reviewing the relevant literature, clinicians can improve their understanding of TA-PAI.

BACKGROUND: Elevated susceptibility to acute myocardial infarction and various cardiovascular diseases has been observed in individuals infected with the human immunodeficiency virus compared with the uninfected population, as demonstrated in numerous studies. The precise mechanism by which human immunodeficiency virus infection heightens the risk of acute myocardial infarction remains elusive. The manifestation of acute coronary syndrome in young patients with human immunodeficiency virus may deviate from the typical, displaying distinct pathophysiological and clinical characteristics. The occurrence of myocardial infarction with non-obstructive coronary arteries in young patients with human immunodeficiency virus poses diagnostic and treatment challenges. CASE PRESENTATION: We present the case of a 46-year-old African woman with no traditional atherosclerotic risk factors. She was diagnosed with human immunodeficiency virus-1 infection 2 years prior to her current admission for chest pain. Her troponin levels were elevated, suggestive of acute coronary syndrome. Although coronary angiography ruled out coronary artery stenosis, it revealed mild myocardial bridging in the left anterior descending artery. Cardiac magnetic resonance imaging confirmed myocardial infarction, indicating a myocardial infarction with non-obstructive coronary arteries with an apical thrombus in the left ventricle. Following medical treatment, the patient experienced resolution of chest pain and improvement in ST-segment elevation. CONCLUSIONS: In young female patients without traditional risk factors, human immunodeficiency virus infection is a possible etiological factor for myocardial infarction with non-obstructive coronary arteries. The likely pathophysiological pathway is superficial endothelial cell denudation as a result of chronic inflammation and immune activation.

OBJECTIVES: We evaluated the ability of the assessment of regional wall motion abnormalities (RWMA) detected via transthoracic echocardiography to predict the presence of obstructive coronary artery disease (CAD) in patients presenting with acute chest pain to the emergency department. DESIGN: Prospective single-centre observational study. SETTING: Tertiary care university hospital emergency unit. PARTICIPANTS: Patients presenting to the emergency department with acute chest pain suggestive of obstructive CAD. PRIMARY OUTCOME MEASURE: The primary endpoint was defined as the presence of obstructive CAD, requiring revascularisation therapy. RESULTS: Overall, 657 patients (age 58.1±18.0 years, 53% men) were included in our study. RWMA were detected in 76 patients (11.6%). RWMA were significantly more frequent in patients reaching the primary endpoint (26.2% vs 7.6%, p<0.001). In multivariable regression analysis, the presence of RWMA was associated with threefold increased odds of the presence of obstructive CAD (3.41 (95% CI 1.99 to 5.86), p<0.001). Adding RWMA to a multivariable model of the Thrombolysis in Myocardial Infarction (TIMI) risk score, cardiac biomarkers and traditional risk factors significantly improved the area under the curve for prediction of obstructive CAD (95% CI 0.777 to 0.804, p=0.0092). CONCLUSION: RWMA strongly and independently predicts the presence of obstructive CAD in patients presenting with acute chest pain to the emergency department. TRIAL REGISTRATION: The study has been registered online (NCT03787797).

Coronary risk scores, such as History, Electrocardiogram, Age, Risk Factors, and Troponin (HEART) and Emergency Department Assessment of Chest Pain Score (EDACS) scores, help nurses identify suspected acute coronary syndrome (ACS) patients who have a risk for major adverse cardiac events (MACE) within 30 days. AIM: To compare the accuracy of HEART and EDACS scores in predicting major events among patients suspected of ACS in the cardiac emergency department (ED). DESIGN AND METHODS: A prospective correlational observational study design was performed on cardiac ED patients who presented with suspected ACS. TOOLS: Three tools were utilized to collect data pertinent to the study: Tool I comprises patients' assessment (personal characteristics, risk factors for ACS, and chest pain assessment sheet); Tool II is the risk assessment tool that includes HEART and EDACS scores; and Tool III is MACE incidence among studied patients within 30 days. RESULTS: HEART score was significantly (P < .01) higher among patients for whom MACE was present than absent. However, EDACS score showed no significant difference (P > .05) among patients whose MACE was present or absent. HEART risk score >6 correctly predicted MACE cases with sensitivity and specificity of 77.46% and 48.28%, respectively. However, EDACS score >18 correctly predicted MACE cases with sensitivity and specificity of 42.25% and 75.86%, respectively. CONCLUSION: This study concludes that HEART score has better sensitivity than EDACS in predicting MACE among suspected ACS patients at the cardiac ED. The HEART score provides the nurses with a quicker and more reliable predictor of MACE shortly after the arrival of the suspected ACS patients at the cardiac ED than the EDACS score. The study recommended the implementation of a HEART score in the cardiac ED for predicting MACE in suspected ACS patients. Follow up closely for high-risk patients to MACE. An educational program should be made for nurses about the implementation of the heart score in the cardiac ED.

BACKGROUND: Pleural effusion indicates an imbalance between pleural fluid formation and removal. Classified into exudative and transudative, with common symptoms of dry cough, dyspnea and pleuritic chest pain. Confirmed etiology has to be established for effective treatment. OBJECTIVE: Correlate clinical and biochemical profile of various etiologies of pleural effusion. MATERIALS & METHODS: Retrospective observational study of 2 years in the department of respiratory medicine, GMC Bhopal on 280 cases of pleural effusion. RESULTS: Most common etiology was tubercular 202 (72.4%) followed by malignant in 36 (12.8%). With respect to tubercular, malignant pleural effusion has relative risk (RR) of 0.138 (p value < 0.05) in the age group of 51-60 years, which is statistically significant. Patients of tuberculosis complained of fever 158 (78.2%) whereas with malignancy complained of chest pain 16 (44.4%) followed by hemoptysis 12 (33.3%). For hemoptysis, with respect to tubercular, malignant effusion has RR of 5.68 (p value < 0.05) which is significant. History of smoking was significant in malignant effusion with RR of 2.57 (p value < 0.05) as compared to tubercular. Pleural fluid ADA was >70 in 83.7% in tubercular effusion, glucose was <60 mg/dl in 79% tubercular, malignant and bacteriological cause, LDH was >1000 in 88.4% in bacteriological and 72.3% in malignant effusion. CONCLUSION: Lack of tools for confirming diagnosis leads to diagnostic dilemma and delay in treatment initiation, leading to deterioration and untoward fatality in some cases. Our goal is early diagnosis by correlating clinical symptoms with biochemical profile and help initiate rapid treatment.

INTRODUÇÃO: A cirurgia de revascularização miocárdica continua sendo realizada em grande número de pacientes. Apesar dos enxertos arteriais serem preferidos devido sua patência, enxertos de veia safena continuam sendo usados regularmente. Os aneurismas de enxertos venosos são uma rara complicação cirúrgica tardia, aprensentandose em média 10 anos após a revascularização. A maioria dos pacientes com aneurisma são assintomáticos e suas principais complicações são embolização distal, IAM e formação de fístula e rotura. RELATO DE CASO: Paciente feminina, 65 anos, com antecedente de RVM com ponte mamária para coronária descendente anterior (MIE-DA) e pontes safena para diagonal, primeiro e segundo marginal e coronária direita. Em cateterismo 2023, ponte MIE-DA estava pérvia, com oclusão das demais. Relatou dor torácica típica, com piora do padrão há 15 dias. Apresentou ECG com padrão de isquemia circunferencial e curva ascendente de troponina, sendo Internada por IAMSSST. No ecocardiograma visualizou-se aumento da porção distal de aorta ascendente com grande dilatação e formação de uma neocavidade medindo 63x57mm, adjacente a parede posterior da aorta ascendente próximo a junção sinotubular com fluxo, rechaçando a parede do átrio esquerdo e o anel valvar mitral e possível compressão do tronco da coronária esquerda e artéria pulmonar. À ressonância cardíaca evidenciou neocavidade junto à raiz da aorta e porção ascendente com sinais de compressão extrínseca importante das artérias pulmonares. Foi considerado como hipótese diagnóstica um aneurisma do enxerto Ao-MG2, com compressão extrínseca da circulação coronariana causando dor e isquemia. DISCUSSÃO: Aneurisma de enxertos venosos geralmente são assintomáticos, mesmo quando possuem diâmetros entre 5 e 10 cm. A compressão do leito coronariano nativo por efeito de massa pode levar a IAM, até mesmo com alteração de ECG, como observado no caso relatado. O tratamento mais comumente proposto é a correção cirúrgica, contudo, em pacientes com múltiplas toracotomias e alto risco cirúrgico, pode-se optar pela embolização percutânea. CONCLUSÃO: Apesar de complicação relativamente rara, os aneurismas de enxertos venosos devem ser considerados diante de episódio de dor torácica em pacientes previamente submetidos à revascularização miocárdica.

INTRODUÇÃO: Os sinais de alarme de disfunção de bioprótese como espessamento de folhetos, aumento de gradientes transprotéticos, redução do orifício efetivo de fluxo (OEF) e início de sintomas de insuficiência cardíaca podem ser comuns entre as diversas etiologias de deterioração protética. Diagnóstico diferencial entre endocardite infecciosa (EI) e disfunção estrutural é de suma importância para a escolha do tratamento. RELATO DE CASO: Homem de 75 anos, com antecedente de troca valvar aórtica por bioprótese nº 23 e revascularização miocárdica em 2008, deu entrada no Pronto-Socorro por quadro de dor torácica, dispneia aos moderados esforços e ortopneia. Realizada estratificação invasiva e descartada síndrome coronariana aguda.Em ecocardiograma transtorácico (ETT) evidenciada bioprótese aórtica com folhetos espessados, mobilidade e abertura reduzidas e imagem sugestiva de ruptura de um dos seus folhetos, gerando refluxo importante, com gradiente sistólico médio (GSM) 32mmHg, OEF 1,4cm², além de disfunção biventricular importante. Diagnosticado disfunção estrutural por fratura de folheto relacionado ao seio de valsalva direito e indicada cirurgia de troca valvar. Todavia, após complementação com ecocardiograma transesofágico (ETE) visualizada imagem adicional ecogênica medindo 7x4mm relacionado ao folheto do seio coronariano esquerdo podendo corresponder a vegetação. Desse modo, tornou-se imperativo descartar EI como outro componente da disfunção, sendo coletadas hemoculturas com resultados negativos. Na ausência de sinais e sintomas infecciosos, foi descartada infecção. Paciente evoluiu com choque cardiogênico (EUROSCORE II de 40,7%), diante da gravidade optado por intervenção percutânea (Valve-in-Valve). Em indução anestésica, paciente apresentou parada cardiorrespiratória em assistolia, sendo revertida após 4 minutos. Implantada prótese Evolut R de tamanho nº23, com acompanhamento intraoperatório por meio de ETE, ao término, visto endoprótese bem posicionada, sem evidências de refluxo, GSM de 10mmHg e OEF de 2cm². Paciente evoluiu com melhora clínica substancial e recebeu alta em boas condições. CONCLUSÃO: O caso destaca a complexidade diagnóstica e terapêutica da disfunção de bioprótese valvar, ilustrando a importância do diagnóstico diferencial entre disfunção estrutural e EI. O descarte infeccioso é imprescindível para realização do Valve-in-Valve. Neste caso, foi a rápida implementação do procedimento que possibilitou desfechos favoráveis ao paciente.

INTRODUÇÃO Os mixomas são tumores primários cardíacos correspondendo em sua grande maioria de natureza benigna e de constituição sólida, sendo a prevalência mais comum no lado esquerdo (75 a 80% dos casos), com predomínio no sexo feminino. Apesar da histogênese mais comum ser benigna deve-se prosseguir com exérese precoce devido às possíveis complicações, em especial morte súbita e acidentes vasculares. O ecocardiograma é o exame diagnóstico de escolha pois caracteriza tamanho, localização e mobilidade da tumoração assim como a capacidade de obstrução e/ou de formação de êmbolos. Outra opção é a ressonância magnética cardíaca pois além das características anatômicas nos fornece dados de características do microambiente do tumor. DESCRIÇÃO DO CASO Paciente do sexo feminino, 40 anos, proveniente de São Paulo (SP). Deu entrada neste Serviço referenciada de hospital secundário com história de palpitações em precórdio associada a dispneia e astenia intensa com duração de 20 minutos há cerca de 3 meses. Nega queixas durante o período interepisódio assim como nega dor torácica. Como antecedentes patológicos possui fibrilação atrial (FA) paroxística com controle de frequência cardíaca com propranolol 40mg/dia e hipertensão arterial sistêmica (HAS) em uso de losartana 50mg/dia. Nega internações prévios devido o quadro supracitado. Em ECOTT realizado no serviço de origem presença de imagem hiperecoica, homogênea, aderida ao septo interatrial em átrio esquerdo medindo em seus maiores diâmetros aproximadamente 2,6x2,2cm sugestiva de mixoma atrial esquerdo. Prosseguindo investigação realizou novo ECOTT no Instituto Dante Pazzanese de Cardiologia (IDPC) onde observou-se imagem sugestiva de linha de dissecção que se inicia logo após a emergência da artéria subclávia esquerda que se estende até a aorta abdominal proximal. Atualmente recebendo propranolol 40mg/dia e losartana 50mg/dia, evoluindo com bons controles pressóricos e frequência cardíaca sendo programado a exérese de mixoma localizado em atrial esquerdo pela equipe do miocárdio do IDPC e posterior acompanhamento no ambulatório da equipe. CONCLUSÃO Apesar de se tratar de tumores raros e possuírem histologia benigna, os mixomas devem ser investigados e prosseguir com ressecção tumoral com brevidade, devido aos riscos de embolização. Idealmente a investigação deve ser iniciada com o ecocardiograma, seja o transesofágico ou transtorácico, como foi no caso relatado acima onde flagrou-se o mixoma em átrio esquerdo.

INTRODUÇÃO A endomiocardiofibrose (EMF) é uma cardiomiopatia restritiva, caracterizada por envolvimento fibrótico do endocárdio e miocárdio normalmente na região apical, levando a disfunção diastólica, porém, preservando função sistólica. É uma doença de etiologia desconhecida e ainda muito relacionada a países subdesenvolvidos com forte relação às síndromes hipereosinofilicas. Seu diagnóstico pode ser aventado através do ecodopplercardiograma e ressonância magnética cardíaca, podendo muitas vezes ser confundida com trombo em região apical ventricular. DESCRIÇÃO DO CASO Paciente de 38 anos, feminina, proveniente de São Paulo capital. Relata internação anterior há 4 meses em serviço externo por quadro de dor torácica com alteração de enzimas cardíacas, porém, sem evidência de coronariopatia isquêmica na Cinecoronariografia. Evidenciado em ecocardiograma transtorácico (ECOTT) uma hipertrofia excêntrica do ventrículo esquerdo (VE) com imagem hiperecogênica em região apical de 19mm podendo corresponder a trombo. Prosseguindo a investigação, realizada uma ressonância magnética cardíaca descrevendo trombo aderido à parede do ventrículo esquerdo, medindo 2,3 cm, além de hipocinesia dos segmentos apicais e realce miocárdico tardio subendocárdico não transmural nos segmentos apicais. A mesma comparece ao serviço com novo episódio de dispneia e dor precordial, agora com sinais de hipervolemia e hipereosinofilia (>1500). Em novo ECOTT realizado evidenciou-se aumento biatrial, disfunção sistólica do ventrículo direito, hipertensão pulmonar, refluxo de grau importante em valva mitral e tricúspide associado a uma obliteração do ápice em parede endocárdica até base do VE, poupando demais paredes, sugestivo de EMF. Com base nos exames iniciais, configurou-se o diagnóstico de EMF pela ressonância magnética e sua correlação com hipereosinofilia. Dessa forma, após o diagnóstico a paciente evolui com melhora clínica e seguirá tratamento em ambulatório do miocárdio. CONCLUSÕES Relatamos um caso de EMF associada a hipereosinofilia ainda em investigação etiológica. O caso supracitado traz uma paciente jovem proveniente de um país em desenvolvimento com diagnóstico de uma doença ainda pouco compreendida e de difícil diagnóstico, podendo muitas vezes passar-se como um trombo em região apical cardíaca, gerando subdiagnósticos e manejo incorreto.

BACKGROUND: Patients with low HEART (History, Electrocardiogram, Age, Risk factors, and Troponin level) risk scores who are discharged from the emergency department (ED) may present clinical challenges and diagnostic dilemmas. The use of downstream non-invasive stress imaging (NISI) tests in this population remains uncertain. Therefore, this study aims to investigate the value of NISI in risk stratification and predicting cardiac events in patients with low-risk HEART scores (LRHSs). METHODS: We prospectively included 1384 patients with LRHSs between March 2019 and March 2021. All the patients underwent NISI (involving myocardial perfusion imaging/stress echocardiography). The primary endpoints included cardiac death, non-fatal myocardial infarction and unplanned coronary revascularisation. Secondary endpoints encompassed cardiovascular-related admissions or ED visits. RESULTS: The mean patient age was 64±14 years, with 670 (48.4%) being women. During the 634±104 days of follow-up, 58 (4.2%) patients experienced 62 types of primary endpoints, while 60 (4.3%) developed secondary endpoints. Multivariable Cox models, adjusted for clinical and imaging variables, showed that diabetes (HR: 2.38; p=0.008), HEART score of 3 (HR: 1.32; p=0.01), history of coronary artery disease (HR: 2.75; p=0.003), ECG changes (HR: 5.11; p<0.0001) and abnormal NISI (HR: 16.4; p<0.0001) were primary endpoint predictors, while abnormal NISI was a predictor of secondary endpoints (HR: 3.05; p<0.0001). CONCLUSIONS: NISI significantly predicted primary cardiac events and cardiovascular-related readmissions/ED visits in patients with LRHSs.
