Miocarditis lúpica: reporte de un caso / Lupus myocarditis: a case report / Miocardite lúpica: relato de um caso

El término miocarditis hace referencia a una inflamación del miocardio, que puede tener diversas causas (infecciones, tóxicos, enfermedades autoinmunes). Su diagnóstico es desafiante debido al gran espectro de presentaciones clínicas que puede adoptar, muchas veces imitando patologías más prevalentes como el infarto agudo de miocardio. La miocarditis asociada a enfermedades autoinmunes es poco frecuente, y la importancia de reconocerla radica en que el diagnóstico e inicio temprano del tratamiento son cruciales para mejorar su pronóstico. Presentamos aquí un caso clínico de una perimiocarditis lúpica.

Myocarditis refers to an inflammation of the myocardium, which can have various causes (infections, toxic substances, autoimmune diseases). Its diagnosis is challenging due to the wide spectrum of clinical presentations, often mimicking more prevalent pathologies such as acute myocardial infarction. Myocarditis associated with autoimmune diseases is rare, and the importance of recognizing is that early diagnosis and initiation of treatment are crucial to improve its prognosis. We present here a clinical case of lupus perimyocarditis.

O termo miocardite refere-se a uma inflamação do miocárdio, que pode ter várias causas (infecções, substâncias tóxicas, doenças autoimunes). Seu diagnóstico é desafiador devido ao amplo espectro de apresentações clínicas que pode ter, muitas vezes mimetizando patologias mais prevalentes como o infarto agudo do miocárdio. A miocardite associada a doenças autoimunes é rara, e a importância de reconhecê-la reside no fato de que o diagnóstico precoce e o início do tratamento são cruciais para melhorar seu prognóstico. Apresentamos aqui um caso clínico de perimiocardite lúpica.

Miopericarditis aguda versus síndrome coronario agudo: reporte de un caso / Acute myopericarditis versus acute coronary syndrome: case report / Miopericardite aguda versus síndrome coronariana aguda: relato de um caso

La miopericarditis aguda es una pericarditis aguda con compromiso miocárdico menor. En las primeras horas de evolución el cuadro clínico puede confundirse con un síndrome coronario agudo, en especial cuando el electrocardiograma presenta elevación del segmento ST y marcadores de necrosis miocárdica elevados. La resonancia magnética cardíaca tiene un papel importante para diferenciar las dos enfermedades. Presentamos el caso de un hombre de 36 años de edad ingresado por dolor de pecho, elevación del segmento ST y de marcadores de necrosis miocárdica. Se realiza angiografía coronaria, que no evidencia lesiones angiográficamente significativas, resonancia magnética cardíaca con contraste de gadolinio, en la que se observa leve derrame pericárdico, presencia de edema y realce tardío con patrón parcheado subepicárdico e intramiocárdico en pared lateral. Los hallazgos del estudio confirman el diagnóstico de miopericarditis.

Acute myopericarditis is an acute pericarditis with minor myocardial compromise. During the first hours from onset the clinical presentation can be confused with an acute coronary syndrome, especially when the electrocardiogram presents with ST segment elevation and increased markers of myocardial necrosis. Cardiac magnetic resonance imaging plays an important role to differentiate between these two diseases. We present the case of a 36-year-old male who was admitted with chest pain, ST segment elevation and increased markers of myocardial necrosis. Coronary angiography is performed reporting no significant angiographic findings. Cardiac magnetic resonance imaging with contrast medium (gadolinium) is performed, reporting mild pericardial effusion, presence of edema, and delayed uptake with a subepicardial and intramyocardial patchy pattern on the lateral wall. These test findings confirm the diagnosis of myopericarditis.

A miopericardite aguda é uma pericardite aguda com pequena deterioração miocárdica. Nas primeiras horas de evolução do quadro clínico podem ser confundidas com síndrome coronariana aguda, principalmente quando o eletrocardiograma mostra supradesnivelamento do segmento ST e marcadores elevados de necrose miocárdica. A ressonância magnética cardíaca desempenha um papel importante em distinguir as duas doenças. Apresentamos o caso de um homem de 36 anos admitido por dor torácica, supradesnivelamento do segmento ST e elevação dos marcadores de necrose miocárdica, foi realizada cineangiocoronariografia, onde não foram evidenciadas lesões angiograficamente significativas. Foi realizada a ressonância magnética cardíaca com contraste de gadolínio e foram observados derrame pericárdico leve, edema e realce tardio com um padrão irregular subepicárdico e intramiocárdico na face lateral. Os resultados do estudo confirmam o diagnóstico de miopericardite.

Miocarditis fulminante en adultos por el virus de la influenza B: reporte de dos casos y revisión de la literatura / Fulminant myocarditis due to the influenza B virus in adults: Report of two cases and literature review

Resumen La miocarditis es una enfermedad inflamatoria del miocardio. Las infecciones virales son la causa más común, aunque también puede deberse a reacciones de hipersensibilidad y de etiología autoinmunitaria, entre otras. El espectro clínico de la enfermedad es variado y comprende desde un curso asintomático, seguido de dolor torácico, arritmias y falla cardiaca aguda, hasta un cuadro fulminante. El término 'fulminante' se refiere al desarrollo de un shock cardiogénico con necesidad de soporte vasopresor e inotrópico o dispositivos de asistencia circulatoria, ya sea oxigenación por membrana extracorpórea o balón de contrapulsación intraaórtico. Cerca del 10 % de los casos de falla cardiaca por miocarditis corresponde a miocarditis fulminante. La miocarditis por influenza se considera una condición infrecuente; no obstante, su incidencia ha aumentado desde el 2009 a raíz de la pandemia de influenza por el virus AH1N1. Por su parte, la miocarditis por influenza de tipo B sigue siendo una condición infrecuente. Se describen aquí dos casos confirmados de miocarditis fulminante por el virus de la influenza B atendidos en un centro cardiovascular, que requirieron dispositivos de asistencia circulatoria mecánica.

Abstract Myocarditis is an inflammatory disease of the myocardium. Viral infections are the most common cause, although it can also be due to hypersensitivity reactions and autoimmune etiology, among other causes. The clinical spectrum of the disease is varied, from an asymptomatic course, followed by chest pain, arrhythmias, and acute heart failure, to a fulminant episode. The term fulminant refers to the development of cardiogenic shock with a need for vasopressor support and inotropic or assisted circulation devices either extracorporeal membrane oxygenation (ECMO) or intra-aortic counterpulsation balloon. About 10% of cases of heart failure due to myocarditis correspond to fulminant myocarditis. Influenza myocarditis has been considered an infrequent condition. However, its incidence has increased since 2009 as a result of the AH1N1 pandemic; otherwise, myocarditis due to the Influenza type B virus remains an infrequent entity. We describe the experience in a cardiovascular center of two confirmed cases of fulminant myocarditis due to influenza B that required circulatory assistance devices.

Efficacy of echocardiographic criteria for diagnosis of carditis in acute rheumatic fever.

Background: There is a great need forECHOcriteria for accurate diagnosis of carditis in acute rheumatic fever. Aim: To propose and test the efficacy of ECHO criteria for accurate diagnosis of carditis. Material and Methods: The 333 cases underwent detailed clinical examination, laboratory tests and meticulous Echocardiographic study.Vijay’s ECHO criteria for the diagnosis of carditis / subclinical valvulitis was used. 220 (66.06%) cases were both Jones’ positive and ECHO positive [True +ve], 52 cases (15.61%), probably had subclinical carditis as murmur was not heard (Jones’-ve) but ECHO was positive [False - ve]. Four cases, clinically diagnosed as carditis were Jones’+ve ,but ECHO showed congenital heart disease [False +ve]. 57 cases (17.11%) were clinically , echocardiographically and Jones’ negative were taken as control (True –ve). Sensitivity is81%and specificity is 93%. Conclusions: Precise diagnosis of both carditis /subclinical valvulitis is possible with Vijay’s ECHO criteria. ECHO should be included as a major criterion in Jones’criteria.

Ressonância magnética cardíaca na cardiomiopatia dilatada: atualidades / Cardiac magnetic resonance in dilated cardiomyopathy: an update

JUSTIFICATIVA E OBJETIVOS: A cardiomiopatia dilatada(CMD) é a mais comum das cardiomiopatias, compreendendo mais de 90% de todos os casos. O seu diagnóstico é feito, sobretudo,com a utilização da ecocardiografia, a qual apresenta algumas limitações quanto à identificação da etiologia. A ressonância magnética cardíaca (RMC) tem se destacado como exame coadjuvante, permitindo melhor caracterização morfofuncional e tecidual do músculo cardíaco. O objetivo deste estudo foi descrevero papel da RMC no diagnóstico e avaliação das diversas causas de CMD.CONTEÚDO: A RMC apresentou bons resultados na aplicaçã oclínica em diversas causas de CMD, não possuindo capacidade de diferenciar todos os seus tipos, porém, contribuindo para a presunção diagnóstica.CONCLUSÃO: Com o avanço tecnológico da RMC, múltiplas indicações clínicas têm surgido em algumas ocasiões, com um aspecto complementar a determinados exames, em outras, como solução de dilemas diagnósticos. Tudo isso com acurácia superior aos demais métodos de imagem, poucas contraindicações e mínimos riscos de efeitos adversos.(AU)

BACKGROUND AND OBJECTIVES: Dilated cardiomyopathy (DCM) is the most common cause of cardiomyopathies,including more than 90% of all cases. Its diagnostic is done using, especially, echocardiography; which presents some limitations regarding the etiology's identification. Cardiac magnetic resonance (CMR) has been very useful as a more precise study, allowing better characterization of myocardium tissue and morphology. The objective of this article was to describe the role of the CMR in the diagnosis and evaluation of the diverse causes of DCM.CONTENTS : The CMR presented good results in the clinical applicationin diverse causes of DCM, not having capacity to differentiate all their types; however, better contributing to the diagnostic and patients follow up.CONCLUSION: With the technological development of CMR, several clinical indications have been created, in a few occasions with a complementing aspect to certain exams, in others with solutions of diagnostic dilemmas. All with higher accuracy in comparison to others image modalities, few contraindications and minimum adverse risks effects.(AU)

Role of colour flow doppler echocardiography in the identification of acute rheumatic carditis in children without clinical evidence of carditis

This study was carried out on 70 patients: 15 patients with presumptive diagnosis of acute rheumatic fever [group one], 25 patients with no clinical evidence of carditis [group two] and 30 patients with a clinical evidence of carditis [group three] in addition to 20 healthy children as control group A and another 20 normal children [control group B] formed a comparison group for 14 patients of group two. The results revealed that mitral valve thickening was detected in group three [100%], but only in 28% of group two and 20% of group one. All patients had normal left ventricular systolic function. Congestive heart failure was invariably associated with the presence of hemodynamically significant valve lesions. The specificity of Doppler for detecting pathologic mitral regurgitation was 100% with a positive predictive value of 100%. A pathologic mitral regurgitation was identified in 100% of group three versus 48% in group two and 33.5% in group one and it was evident in seven patients with echocardiographically normal appearance of valve morphology

Usefulness of echocardiography in detection of subclinical carditis in acute rheumatic polyarthritis and rheumatic chorea.

Detailed echocardiographic analysis was performed in 10 children with first episode of acute rheumatic fever who presented with acute rheumatic polyarthritis or rheumatic chorea and had no clinically detectable evidence of active carditis. Significant changes were observed in the form of mitral valve prolapse with regurgitation in 3, aortic valve prolapse with regurgitation in 1 and mitral valve billowing without regurgitation in 1 patient each. A significant (p < 0.001) anterior mitral chordal elongation was observed in both the groups--rheumatic polyarthritis and chorea when compared with age and sex matched control subjects. Mitral annular diameter was found to be increased (p < 0.001) in patients presenting with polyarthritis alone. These observations of clinically silent but echocardiographically detectable element of carditis forms the basis of how patients of acute rheumatic fever develop permanent valvular deformities in their latter lives without revealing any cardiac affection earlier.
