Histopatología y Strain auricular en pericarditis constrictiva y miocardiopatía restrictiva / Histopathology and Atrial Strain in Constrictive Pericarditis and restrictive cardiomyopathy

Resumen La pericarditis constrictiva y la miocardiopatía restrictiva son enfermedades raras caracterizadas por síntomas de insuficiencia cardíaca congestiva. El objetivo de este estudio es mostrar el diagnóstico diferencial de estas dos patologías, mediante strain auricular y establecer su correlación con la histopatología de corazones correspondientes. Se analizan 2 casos clínicos representativos de cada una de estas patologías. Se analizan sus presentaciones clínicas, los datos ecocardiograficos y en ambos casos se realizaron biopsias endomiocardicas con lo cual se presenta la correlación histológica. El strain auricular permitió evaluar la afección de las aurículas, consideramos que el strain auricular disminuido podría estar relacionado con la presencia de fibrosis.

Abstract Histopathology and Atrial Strain in Constrictive Pericarditis and restrictive cardiomyopathy Constrictive pericarditis and restrictive cardiomyopathy are rare diseases characterized by congestive heart failure symptoms. The aim of this study is to show the differential diagnosis of these two pathologies using strain and to establish their correlation with histopathology of the corresponding hearts. Two representative clinical cases of each of these pathologies are analyzed. Their clinical presentations, echocardiographic data, and endomyocardial biopsies were performed in both cases, thus presenting the histological correlation. Atrial strain allowed us to evaluate the affection of the atria, we consider that decreased atrial strain could be related to the presence of fibrosis.

Hepatomegalia como forma de presentación en pericarditis constrictiva: Caso clínico pediátrico / Hepatomegaly as a form of presentation in constrictive pericarditis: A pediatric clinical case

La pericarditis constrictiva es una entidad poco frecuente en pediatría, en la cual existe una limitación para la diástole cardíaca por fibrosis del pericardio. El origen etiopatogénico de esta patología es múltiple, encontrándose en primer lugar, la pericarditis constrictiva idiopática y, en segundo, la infección por Mycobacterium tuberculosis. El diagnóstico constituye un desafío clínico, ya que requiere de un alto grado de sospecha. Suele presentarse de forma oligosintomática. La presencia de edema, ascitis y alteración de la función hepática suele orientar el estudio hacia una enfermedad hepática primaria. Una cuidadosa historia clínica y examen físico, junto con estudios por imágenes adecuados, constituyen las piedras angulares del diagnóstico. El tratamiento quirúrgico realizado de forma oportuna resulta curativo en la gran mayoría de los pacientes. Se presenta el caso de un paciente de 16 años que inicia estudios por hallazgo de hepatomegalia asociada a disnea grado 1-2 en un control de salud habitual.

Constrictive pericarditis is a rare entity in pediatrics in which there is a limitation for cardiac diastole due to fibrosis of the pericardium. The etiopathogenic origin of this pathology is multiple, finding idiopathic constrictive pericarditis firstly and Mycobacterium tuberculosis infection secondly. Diagnosis is a clinical challenge since it requires a high degree of suspicion. It usually presents as oligosymptomatic or with signs and symptoms of low cardiac output. The presence of edema, ascites and impaired liver function usually guides the study towards primary liver disease. A careful clinical history and physical examination together with adequate imaging studies are the cornerstones of the diagnosis. Surgical treatment is curative in the vast majority of patients. We present the case of a 16-year-old patient with hepatomegaly and dyspnea grade 1-2 found in a routine health check-up.

Calcificación heterotópica miocárdica y pericarditis constrictiva en contexto de sepsis por a propósito de un caso / Case Report: Myocardial heterotopic calcification and constrictive pericarditis in the context of sepsis due to

We report the case of a 21 years old woman without history of cardiovascular disease, who after her first euthocic delivery, did complain of genital infection of white parts complicated by pneumonia and pyothorax, isolating Streptococcus pyogenes, requiring intensive care, inotropic and vasoactive medication. Transesophageal echocardiography showed constrictive pericarditis and myocardial heterotopic calcification in the context of sepsis. Subsequently, the pericardial constriction and clinical symptoms improved, with persistent calcifications. The echocardiogram prior to delivery was completely normal.

Presentamos el caso de una mujer de 21 años sin antecedentes cardiovasculares quien posterior a primer parto eutócico simple presenta infección genital de partes blancas complicada con neumonía y piotórax, aislándose Streptococcus pyogenes, ameritando cuidados intensivos, inotrópicos y vasoactivos. El ecocardiograma transesofágico evidenció pericarditis constrictiva y calcificación heterotópica miocárdica en contexto de sepsis. Posteriormente mejoró el cuadro de constricción pericárdica y la clínica, persistiendo las calcificaciones. El ecocardiograma previo al parto se encontraba completamente normal.

Importance of Clinical and Laboratory Findings in the Diagnosis and Surgical Prognosis of Patients with Constrictive Pericarditis / Importância dos Achados Clínicos e Laboratoriais no Diagnóstico e Prognóstico Cirúrgico de Pacientes com Pericardite Constritiva

Abstract Background: International studies have reported the value of the clinical profile and laboratory findings in the diagnosis of constrictive pericarditis. However, Brazilian population data are scarce. Objective: To assess the clinical characteristics, sensitivity of imaging tests and factors related to the death of patients with constrictive pericarditis undergoing pericardiectomy. Methods: Patients with constrictive pericarditis surgically confirmed were retrospectively assessed regarding their clinical and laboratory variables. Two methods were used: transthoracic echocardiography and cardiac magnetic resonance imaging. Mortality predictors were determined by use of univariate analysis with Cox proportional hazards model and hazard ratio. All tests were two-tailed, and an alpha error ≤ 5% was considered statically significant. Results: We studied 84 patients (mean age, 44 ± 17.9 years; 67% male). Signs and symptoms of predominantly right heart failure were present with jugular venous distention, edema and ascites in 89%, 89% and 62% of the cases, respectively. Idiopathic etiology was present in 69.1%, followed by tuberculosis (21%). Despite the advanced heart failure degree, low BNP levels (median, 157 pg/mL) were found. The diagnostic sensitivities for constriction of echocardiography and magnetic resonance imaging were 53.6% and 95.9%, respectively. There were 9 deaths (10.7%), and the risk factors were: anemia, BNP and C reactive protein levels, pulmonary hypertension >55 mm Hg, and atrial fibrillation. Conclusions: Magnetic resonance imaging had better diagnostic sensitivity. Clinical, laboratory and imaging markers were associated with death.

Resumo Fundamento: Estudos internacionais têm relatado o valor de perfil clínico e exames de imagem no diagnóstico e prognóstico da pericardite constritiva. Entretanto, dados da população brasileira são escassos. Objetivo: Avaliar as características clínicas, sensibilidade de exames de imagem e fatores relacionados ao óbito em uma série de casos de pericardite constritiva submetidos à pericardiectomia. Métodos: Pacientes com pericardite constritiva confirmada por cirurgia foram avaliados retrospectivamente quanto a variáveis clínicas e laboratoriais. Dois métodos diagnósticos foram utilizados: ecocardiograma transtorácico e ressonância cardíaca. Preditores de mortalidade foram determinados por análise univariada usando metodologia das proporções de Cox e hazard ratio. Todos os testes foram considerados bicaudais e um erro alfa ≤ 5% foi considerado como significante. Resultados: Foram estudados 84 pacientes com idade média de 44 ± 17,9 anos, sendo 67% do sexo masculino. Sinais e sintomas de insuficiência cardíaca (IC) predominantemente direita estiveram presentes com estase jugular, edema e ascite em 89%, 89% e 62% dos casos, respectivamente. Etiologia idiopática foi observada em 69% dos casos, seguida por tuberculose em 21%. Apesar do grau de IC, encontramos baixos níveis de BNP (mediana de 157 pg/mL). As sensibilidades diagnósticas para constrição do ecocardiograma e da ressonância foram 53,6% e 95,9%, respectivamente. Durante a evolução clínica, houve 9 óbitos (10,7%) e os fatores de risco foram: anemia, elevações de BNP, PCR, hipertensão pulmonar > 55 mmHg e fibrilação atrial. Conclusões: Pericardite constritiva manifesta-se com sinais e sintomas de IC biventricular com predomínio à direita e baixos níveis de BNP. A ressonância magnética apresenta melhor sensibilidade para diagnóstico. Marcadores clínicos, laboratoriais e de imagem estiveram associados ao óbito.

Pericarditis constrictiva, siempre un desafío diagnóstico / Constrictive pericarditis: always a diagnostic challenge

Reportamos el caso de un hombre de 52 años, con antecedente de larga data de dolor torácico, estudiado el año 2005 con una coronariografía que descarta lesiones en las arterias epicárdicas. Se agrega luego de forma progresiva dolor y distensión abdominal. Sin controles hasta el año 2015, cuando se realiza una endoscopia digestiva alta que no objetiva hallazgos patológicos, encontrándose el paciente en fibrilación auricular e iniciando terapia. A fines del 2016 por persistencia y aumento de las molestias se hospitaliza en nuestro centro para estudio. Se realiza una ecocardiografía que evidencia; severa dilatación biauricular, buena función global y segmentaria bi-ventricular y un movimiento de rebote protodiás-tolico que aumentaba notoriamente en inspiración a nivel del septum interventricular. El pericardio se encontraba engrosado e hiperrefringente de forma difusa, con falta de deslizamiento entre sus hojas y movimiento en bloque de los tejidos blandos adyacentes. Presentaba además comportamiento reverso del anillo mitral al Doppler tisular y la vena cava inferior se encontraba dilatada y sin variación con el ciclo ventilatorio. Un sondeo cardíaco izquierdo y derecho descarta lesiones coronarias y corrobora la fisiología constrictiva. Se amplía el estudio con una tomografía computada de tórax que informa engrosamiento difuso y extensa calcificación del pericardio, además de signos de daño hepático crónico. Se realiza una pericardiotomia exitosa, los hallazgos del intraoperatorio e histopatológicos confirman el diagnóstico de pericarditis constrictiva calcificada. El paciente es dado de alta al quinto día postoperatorio sin incidentes.

We report the case of a 52 y.o. male, with longstanding history of chest pain. Coronariography performed in 2005 showed normal coronary arteries. In the following years he developed progressive abdominal bloating and pain, upper gastrointestinal endoscopy was normal, but atrial fibrillation was diagnosed initiating therapy. During the year 2016 symptoms got worse, being admitted to our hospital. Echocardiography revealed severe biatrial enlargement, preserved bi-ventricular function, and a paradoxical bouncing motion of the interventricular septum which augmented during inspiration (septal bounce). The pericardium was thickened with absence of normal sliding between its layers, and traction of adjacent soft tissues was observed. Mitral ring tissue Doppler showed reversal of lateral and medial e' velocities. Inferior vena cava was dilated with no respiratory variation. Cardiac catheterization was consistent with constrictive pericarditis. Computed tomography confirm extensive pericardial calcification and thickness and found signs of chronic liver disease. Uneventful pericardiectomy was performed, intraoperative and histological findings confirm the diagnostic of calcified pericardial constriction, being discharged on the fifth day post-surgery.

Pericarditis constrictiva como presentación grave e infrecuente de lupus eritematoso sistémico: reporte de un caso y revisión de la literatura / Constrictive pericarditis as a serious and rare presentation of systemic lupus erythematosus: Report of one case

Constrictive Pericarditis (CP) is an unusual disease. Its most common causes are idiopathic or secondary to cardiac surgery. Less frequently it is caused by connective tissue diseases. We report a 30 years old woman hospitalized due to progressive dyspnea, chest pain and signs of right sided heart failure. During her stay, a Systemic Lupus Erythematosus (SLE) was diagnosed. The echocardiogram suggested a CP and the diagnosis was confirmed by cardiac catheterization. Pericardiectomy was successfully performed. The biopsy confirmed a nonspecific chronic pericarditis, with extensive fibrosis and absence of caseating granulomas. The patient had a satisfactory recovery.

Presentación atípica de una pericarditis constrictiva en una paciente con artritis reumatoídea / Atipical constrictive pericarditis in a patient with rheumatoid arthritis

Constrictive pericarditis as an extra articular manifestation of rheumatoid arthritis is very unusual, but it’s valuable to consider as a working diagnosis in patients with symptoms of heart failure that suffer rheumatoid arthritis. In our case report, the first manifestation was severe ascites and anasarca, that after numerous studies led to the diagnosis of constrictive pericarditis.

La pericarditis constrictiva como manifestación extraarticular de la artritis reumatoide constituye una rareza; es valioso, sí, plantearla como hipótesis diagnóstica en pacientes con clínica de insuficiencia cardiaca y que padezcan artritis reumatoide. En nuestro caso clínico la primera manifestación es una anasarca con ascitis severa, y luego de numerosos estudios se pesquisa la pericarditis constrictiva.

Acute Viral Myopericarditis Presenting as a Transient Effusive-Constrictive Pericarditis Caused by Coinfection with Coxsackieviruses A4 and B3

Acute myopericarditis is usually caused by viral infections, and the most common cause of viral myopericarditis is coxsackieviruses. Diagnosis of myopericarditis is made based on clinical manifestations of myocardial (such as myocardial dysfunction and elevated serum cardiac enzyme levels) and pericardial (such as inflammatory pericardial effusion) involvement. Although endomyocardial biopsy is the gold standard for the confirmation of viral infection, serologic tests can be helpful. Conservative management is the mainstay of treatment in acute myopericarditis. We report here a case of a 24-year-old man with acute myopericarditis who presented with transient effusive-constrictive pericarditis. Echocardiography showed transient pericardial effusion with constrictive physiology and global regional wall motion abnormalities of the left ventricle. The patient also had an elevated serum troponin I level. A computed tomogram of the chest showed pericardial and pleural effusion, which resolved after 2 weeks of supportive treatment. Serologic testing revealed coxsackievirus A4 and B3 coinfection. The patient received conservative medical treatment, including nonsteroidal anti-inflammatory drugs, and he recovered completely with no complications.

Diagnóstico diferencial entre cardiomiopatia restritiva e pericardite constrictiva: [revisão] / Differencial diagnosis between restrictive cardiomyopathy and constrictive pericarditis: [review]

O diagnóstico diferencial entre as cardiomiopatias restritivas (CR) e a pericardite constrictiva (PC) é fundamental para o manuseio adequado de pacientes com síndrome restritiva (SR). A diferenciação entre as doenças deve ser embasada nas características anatomopatológicas e fisiopatológicas peculiares a cada afecção. Entretanto, um número expressivo de pacientes com PC tem o miocárdio comprometido. A introdução de novas técnicas da ecocardiografia (Eco) traz a perspectiva de identificação da PC, nessas condições...

Pericardite constritiva com calcificação extensa / Constrictive pericarditis with extensive calcification / Pericarditis constrictiva con calcificación extensa

Paciente com sinais e sintomas de insuficiência cardíaca direita de etiologia desconhecida, transferida para tratamento em hospital de referência da zona leste de São Paulo, com diagnóstico de pericardite constritiva calcificada, tratada cirurgicamente. Essa patologia caracteriza-se por processo de calcificação irreversível do pericárdio, e o tratamento cirúrgico é a alternativa para o controle dos sintomas e a melhora da qualidade de vida dos pacientes. Esse caso chamou a atenção pela extensão da calcificação e por seu local de distribuição, atingindo o septo interventricular, fato que dificultou o diagnóstico pelo aspecto inusitado das imagens, deixando dúvida se haveria outra doença associada.

A patient with signs and symptoms of right heart failure of unknown etiology was referred to a referral hospital in the eastern area of the city of São Paulo with a diagnosis of calcified constrictive pericarditis and was treated by surgery. This pathology is characterized by an irreversible process of pericardium calcification, and surgery is the only alternative to control the symptoms and improve patients' quality of life. This case drew special attention due to the extensive calcification involving the interventricular septum. The unusual aspect of the images has made the diagnosis difficult and raised doubts about the existence of an associated disease.

Pacientes con signos y síntomas de insuficiencia cardíaca derecha, de etiología desconocida, trasladados para recibir tratamiento en un hospital de referencia en la región este de São Paulo, con diagnóstico de pericarditis constrictiva calcificada, tratada quirúrgicamente. Esta patología se caracteriza por un proceso de calcificación irreversible del pericardio, y el tratamiento quirúrgico es la alternativa para el control de los síntomas y la mejora de la calidad de vida de los pacientes. Este caso llamó la atención por la extensión de la calcificación y por su local de distribución, alcanzando el tabique interventricular, lo que dificultó el diagnóstico por el aspecto inusual de las imágenes, dejando dudas sobre si no habría otra enfermedad asociada.

Clínica y seguimiento de la pericarditis constrictiva crónica / Clinical finding and follow up of chronic constrictive pericarditis

El objetivo de este estudio fue describir la etiología, presentación clínica, métodos diagnósticos, tratamiento, evolución y pronóstico alejado de 35 pacientes con pericarditis constrictiva crónica que fueron evaluados prospectivamente de acuerdo a un protocolo de enfermedad pericárdica que se aplica en nuestra Institución. En 24 (68%) la pericarditis constrictiva fue idiopática y 11 (32%) presentaron etiología definida, realizándose pericardiectomía en 34 (97%). Hubo 4 (12%) muertes intrahospitalarias, todas con etiología definida. La mediana de seguimiento fue de 5.6 años (percentilos 25-75: 2.4-7.4 años). La supervivencia de acuerdo al método de Kaplan-Meier fue de 97% al año (IC 95% 80 - 99%), 83% a los 5 años (IC 95% 65 - 93%), 78% a los 7 años (IC 95% 60 - 90%), y 69% a los 10 años (IC 95% - 50% - 84%). En conclusión, la pericarditis constrictiva crónica es una enfermedad generalmente idiopática, de diagnóstico tardío, cuyo tratamiento es la pericardiectomía. Los pacientes con etiología específica presentaron mayor mortalidad intrahospitalaria. En el seguimiento a 10 años 2/3 de los pacientes están vivos y con mejoría de los síntomas.

The aim of this study was to describe the etiology, clinical findings, diagnostic methods, treatment, outcome and long-term prognosis of 35 patients with chronic constrictive pericarditis (CCP) that were prospectively analyzed according to a pericardial disease protocol performed in our Institution. Etiology of CCP was idiopathic in 24 patients (68%), and specific in 11 (32%). The majority (34 patients, 97%) underwent pericardiectomy. Perioperative mortality was 12% (4/33) no deaths were registered among patients with idiopathic CCP. Median follow-up was 5.6 years (percentile 25-75: 2.4-7.4 years). The cumulative actuarial survival probability was 97% at 1 year (confidence interval [CI] 80% to 99%); 83% at 5 years, (95% CI 65% to 93%); 78% at 7 years, (95% CI 60% to 90%), and 69% at 10 years (95% CI 50% to 84%). In conclusion, nowadays CCP is generally an idiopathic disease with late diagnosis. The clinical course of the disease produces severe symptoms of congestive heart failure. In a 10 years follow-up 2/3 of patients are alive and improved their quality of life. Idiopathic form of pericarditis did not show mortality during early postoperative period.

Pericardite constritiva manifestando-se como ascite refratária / Constrictive pericarditis observed as refractory ascites

A pericadite constritiva, causada por espessamento, inflamação ou calcificação pericárdica, é condição limitante ao enchimento diastólico do coração. Seu diagnóstico clínico nem sempre é fácil e suas manifestações clínicas, frequentemente, mimetizam outras patologias, principalmente as causas de congestão venosa sistêmica e de ascite refratária. Existem critérios ecocardiográficos, já bem estabelecidos, que auxiliam nesse diagnóstico diferencial, e a acurácia da ecocardiográfia nessa condição tem tido incrementos importantes, sobretudo com a descrição de novos critérios do Doppler tecidual. Essas técnicas de análise agregam dados inclusive para a diferenciação entre a pericardite constritiva e a miocardiopatia restritiva, o que usualmente representava um desafio. Esse relato demonstra um caso de pericardite constritiva, manifestando-se como ascite refratária que mimetizava hepatopatia, cujo diagnóstico diferencial, confirmado por cirurgia, consistiu em desafio, com participação definitiva da ecocardiografia nas tomadas de decisão.

Níveis séricos de NT pro-BNP: relação com função sistólica e diastólica nas miocardiopatias e pericardiopatias / Serum NT pro-BNP: relation to systolic and diastolic function in cardiomyopathies and pericardiopathies

FUNDAMENTO: O NT pro-BNP é marcador de disfunção sistólica e diastólica. OBJETIVO: Determinar os níveis de NT pro-BNP em pacientes com cardiopatia chagásica, hipertrófica, restritiva e afecções pericárdicas, e sua relação com medidas ecocardiográficas de disfunção sistólica e diastólica. MÉTODOS: Cento e quarenta e cinco pacientes foram divididos nos respectivos grupos: 1) cardiopatia chagásica (CCh) - 14 pacientes; 2) miocardiopatia hipertrófica (CMH) - 71 pacientes; 3) endomiocardiofibrose (EMF) - 26 pacientes; 4) derrame pericárdico (DP) - 18 pacientes; 5) e pericardite constritiva (PC) - 16 pacientes. Foi constituído um grupo-controle de 40 indivíduos sem doença cardíaca. O grau de acometimento miocárdico e o derrame pericárdico foram avaliados pelo ecocardiograma bidimensional e a restrição pelo Doppler pulsátil do fluxo mitral. O diagnóstico de PC foi confirmado por meio da ressonância magnética. Os níveis de NT pro-BNP foram medidos por imunoensaio com detecção por eletroquimioluminescência. RESULTADOS: O NT pro-BNP esteve aumentado (p < 0,001) na CCh (mediana 513,8 pg/ml), CMH (mediana 848 pg/ml), EMF (mediana 633 pg/ml), PC (mediana 568 pg/ml), DP (mediana 124 pg/ml), quando comparados ao grupo-controle (mediana 28 pg/ml). Não foram observadas diferenças estatisticamente significativas entre PC e EMF (p = 0,14). No grupo hipertrófico, o NT pro-BNP correlacionou-se com tamanho de átrio esquerdo (r = 0,40; p < 0,001) e relação E/Ea (p < 0,01). No grupo restritivo, houve uma tendência de correlação com pico de velocidade de onda E (r = 0,439; p = 0,06). CONCLUSÃO: O NT pro-BNP encontra-se aumentado nas diversas miocardiopatias e afecções pericárdicas, e apresenta relação com o grau de disfunção sistólica e diastólica.

BACKGROUND: NT pro-BNP is a marker of systolic and diastolic dysfunction. OBJECTIVE: To determine NT pro-BNP levels in patients with chagasic, hypertrophic, and restrictive heart diseases, as well as with pericardial diseases, and their relation to echocardiographic measurements of systolic and diastolic dysfunction. METHODS: A total of 145 patients were divided into the following groups: 1) Chagas' heart disease (CHD) - 14 patients; 2) hypertrophic cardiomyopathy (HCM) - 71 patients; 3) endomyocardial fibrosis (EMF) - 26 patients; 4) pericardial effusion (PE) - 18 patients; and 5) constrictive pericarditis (CP) - 16 patients. The control group was comprised of 40 individuals with no heart disease. The degree of myocardial impairment and pericardial effusion were assessed by two-dimensional echocardiography and the degree of restriction by pulsed Doppler transmitral flow. The diagnosis of CP was confirmed through magnetic resonance imaging. NT pro-BNP levels were determined through electrochemiluminescence immunoassay. RESULTS: NT pro-BNP was increased (p < 0.001) in CHD (median = 513.8 pg/ml), HCM (median = 848 pg/ml), EMF (median = 633 pg/ml), CP (median = 568 pg/ml), and PE (median = 124 pg/ml), when compared with the control group (median = 28 pg/ml). No statistically significant differences were found between CP and EMF (p = 0.14). In the hypertrophic group, NT pro-BNP was correlated with left atrial size (r = 0.40; p < 0.001) and with E/Ea ratio (p < 0.01). In the restrictive group, there was a trend of correlation with E-wave peak velocity (r = 0.439; p = 0.06). CONCLUSION: NT pro-BNP is increased in the different cardiomyopathies and pericardial diseases and is correlated with the degree of systolic and diastolic dysfunction.
