Massa Valvar Mitral em Paciente com Suspeita de Lúpus Sistêmico: Tumor, Endocardite ou Ambos? / Mitral Valve Mass in a Patient Suspected of Systemic Lupus: Tumor, Endocarditis or Both?

Resumo Apresentamos o relato de caso de uma paciente com mixoma valvar mitral infectado e uma revisão da literatura sobre o assunto. Uma mulher de 33 anos apresentou histórico de febre e dispneia com evolução de alguns dias. Na hospitalização, ela apresentava uma síndrome semelhante ao lúpus, com hemoculturas positivas para Haemophilus spp . O ecocardiograma revelou uma massa gigante envolvendo ambos os folhetos mitrais associada à regurgitação grave, necessitando de troca valvar mitral biológica. A microscopia revelou mixoma infectado e a paciente recebeu alta assintomática após o término da antibioticoterapia. Ela apresentou bons resultados no seguimento. Este é o sexto caso de mixoma valvar mitral infectado relatado na literatura e o terceiro caso de mixoma cardíaco infectado pelo grupo HACEK. Devido à alta incidência de eventos embólicos, a antibioticoterapia precoce aliada à pronta intervenção cirúrgica são decisivos para a redução da morbimortalidade. O tempo para o diagnóstico foi muito mais breve do que o geralmente relatado em casos de endocardite por HACEK. A troca valvar foi a intervenção mais comum e todos os pacientes em relatos de caso anteriores apresentaram bons resultados no seguimento.

Abstract We present a case report of a patient with an infected mitral valve myxoma and a literature review on the subject. A 33-year-old female presented with a history of fever and dyspnea evolving over a few days. On admission, she had a lupus-like syndrome with positive blood cultures for Haemophilus species . Echocardiogram revealed a giant mass involving both mitral leaflets causing severe regurgitation, requiring biological mitral valve replacement. Microscopy showed an infected myxoma and the patient was discharged asymptomatic upon completion of antibiotics. She did well on follow-up. This is the sixth case of an infected mitral valve myxoma reported in the literature and the third case of a cardiac myxoma infected by the HACEK group. Exceedingly high incidence of embolic events makes prompt imaging, antibiotic therapy and surgery crucial for better outcomes. Time to diagnosis was much briefer than usually reported in other cases of HACEK endocarditis. Valve replacement was the most common surgical procedure and all patients from previous reports did well on follow-up.

Clinical and pathological characteristics of cardiac tumors: analyses of 689 cases at a single medical center / 中华病理学杂志

Objective@#To study the clinicopathological characteristics of cardiac neoplasms.@*Methods@#A total of 689 cases of cardiac neoplasms from January 1st 1992 to December 31th 2017 at Guangdong Provincial People′s Hospital were collected. The clinical data and histologic features were analyzed along with a review of literature. The pathological diagnosis and classification were based on the criteria of WHO 4th edition(2015).@*Results@#Among 689 cases of cardiac neoplasms, 259 were male and 430 were female patients, with age from 0 to 84 years (mean of 48 years). The peak incidence was between the fourth and sixth decade. Among patients younger than 20 years, there were 24 males and 12 females. 674 cases(674/689,97.8%)were primary cardiac tumors and 15 cases were secondary tumors (15/689,2.2%). Amongst the primary cardiac neoplasms, 625 cases were benign(625/674,92.7%), 7 cases were borderline (7/674, 1.0%), and 42 cases were malignant (42/674, 6.2%). The incidences of benign, borderline and malignancy heart tumors among patients below 20 years old were lower than those of patients over 20 years of age (4.8% vs. 95.2%; 3/9 vs. 6/9; 5.5% vs. 94.5%, respectively). Of the benign tumors, 406 cases were female and 219 cases were male. More male than female patients were seen in borderline and malignancy cardiac tumor categories (6∶3; 34∶21). Of 625 benign tumors, 577 cases were myxoma(85.6%), which mainly occurred in patients over 20 years of age(85.9% vs. 14.1%) with a female predominance. Non-myxomas mainly occurred in children and adolescent patients compared to adult (55.6% vs. 44.4%, P<0.01) with a male predominance. Overall, 524 tumors originated from the left atrium, 84 cases from the right atrium, 26 cases from the pericardium, 23 cases from the right ventricular, and 11 cases from the left ventricle. However, 21 cases were multicentric or involving cardiac valves. Benign tumors mainly involved left heart(76.3%) vs. right heart(81/625, 12.6%). The mostly common location of borderline tumors was right heart(5/9). Malignant tumors tended to involve the right heart(22/55,40.0%) and pericardium(18/55, 32.7%).@*Conclusions@#Although the incidence of cardiac neoplasms is low,various tumor types can occur, most of which are myxoma with a female predominance. Non-myxomas mainly occur in children and adolescents with a male predominance.

Angiosarcoma cardíaco: una neoplasia infrecuente / Cardiac angiosarcoma: an infrequent neoplasia

Los tumores cardíacos son infrecuentes, siendo los más comunes los metastásicos. De los primarios, sólo el 25 por ciento son malignos, donde el angiosarcoma es el más frecuente. Este corresponde a un tumor de alto grado de malignidad, caracterizado por un rápido crecimiento, obstrucción de válvulas y metástasis principalmente pulmonares. Es más frecuente entre los 30 y 50años, especialmente en el género masculino, con una relación de2:1. Su clínica es de naturaleza cardiovascular inespecífica y su pronóstico es malo, con una supervivencia de entre nueve a doce meses a partir del diagnóstico. Presentación del caso: Paciente de género femenino, de 50 años de edad, con antecedentes de hipertensión arterial y artritis reumatoide. Consultó por disnea y deterioro de capacidad funcional. Ecocardiograma transtorácico mostró masa de seis centímetros de diámetro, que ocupa toda la aurícula derecha y que generaba obstrucción al flujo tricuspídeo, asociado a derrame pericárdico masivo con taponamiento cardíaco. Tomografía computada (TC) de cerebro, tórax, abdomen y pelvis descartan lesiones metastásicas. Se decidió conducta quirúrgica. Se resecó el tumor y el 70 por ciento de la pared libre de la aurícula y se instaló prótesis valvular biológica; con pericardio autólogo se reconstruyó la aurícula derecha. Evolucionó favorablemente, sin incidentes. Estudio histopatológico concluyó angiosarcoma cardíaco. Discusión: Los tumores cardíacos son infrecuentes. Se deben sospechar en pacientes con clínica cardiovascular, asociada a masa intracavitaria, derrame pericárdicono explicable por otra causa, así como la presencia de metástasis torácicas de un tumor primario desconocido...

Introduction: Cardiac tumors are rare; of them, the metastatic tumors are the most frequent. Of the primary tumors, only 25 percent are malignant, being the angiosarcoma the most common. It is a tumor of high malignancy, characterized by rapid growth, obstruction of cardiac valves and lung metastases. It is most common between 30 and 50 years, especially in men, with a ratio of 2:1. Its symptoms are nonspecific cardiovascular and its prognosis is poor, with a survival of nine to twelve months from diagnosis. Case report: A 50 years old woman with a history of hypertension and rheumatoid arthritis. She presented with dyspnea and impaired functional capacity. Transthoracic echocardiogram showed a mass of 6 cm in diameter, occupying the entire right atrium with tricuspid flow obstruction, associated with massive pericardial effusion with cardiac tamponade. Computed tomography (CT) of the brain, thorax, abdomen and pelvis discarded metastatic lesions. Surgical treatment was decided. The tumor and 70 percent of the free wall of the atrium were resected and biological prosthetic valve was installed, and the righ tatrium was reconstructed with autologous pericardium. She evolved favorably, without incident. Histopathological reports confirmed cardiac angiosarcoma. Discussion: Cardiac tumors are rare. They should be suspected in patients with cardiovascular symptoms, associated with intracavitary mass, pericardial effusion not explained by other causes, as well as the presence of thoracic metastases from an unknown primary tumor...

Este estudo teve como objetivo determinar a prevalência e achados anatomopatológicos de tumores primários e metastáticos do coração ou de tecidos da base do coração, diagnosticados em caninos do Sul de Minas Gerais. O diagnóstico foi realizado mediante análise histopatológica e imuno-histoquímica das neoplasias. Durante os anos de 1994-2009, foram realizadas 2397 necropsias em caninos. Neoplasias no coração foram detectadas em 31 cães (1,29%), onde, sete (22,58%) eram primárias e 24 (77,42%) metastáticas. As neoplasias diagnosticadas como primárias do coração foram o hemangiossarcoma (1/7) e o mixoma (1/7); e como primárias da base do coração o quimiodectoma (3/7) e o carcinoma de tireoide ectópica (2/7). A frequência foi maior em cães machos (5/7), da raça Boxer (3/7) e com idade média de 9,7±1,88 anos. Nas neoplasias metastáticas, a frequência foi maior em fêmeas (15/24), em cães da raça Rottweiler (7/24) e a idade média foi de 7,5±3,23 anos, sendo o linfoma de células T a neoplasia metastática de maior ocorrência (7/27).

The purpose of this study was to determine the prevalence and anatomopathological findings of primary and metastatic heart tumors and from heart base tumors diagnosed in dogs from southern Minas Gerais, Brazil. The diagnosis was based on histological characteristics and immunophenotyping of the tumors cells. From 1994 to 2009, 2397 necropsies of dogs were performed. Cardiac neoplasms were diagnosed in 31 dogs (1.29%), where seven (22.58%) were primary and 24 (77.42%) were metastatic. Neoplasms of the heart diagnosed as primary were hemangiosarcoma (1/7) and myxoma (1/7), and, primary of heart base, the chemodectoma (3/7) and ectopic thyroid carcinoma (2/7). Frequency was higher in male dogs (5/7), of Boxer breed (3/7) with mean age of 9.7±1.88 years. In metastatic neoplasms, the frequency was higher in female dogs (15/24), of Rottweiler breed (7/24) with the mean age of 7.5±3.23 years. The T cell lymphoma (7/27) was the most frequent neoplasm, diagnosed as metastatic.

ObjectiveTo Summarize the experience of totally thoracoscopic operation for atrial myxoma.Methods From December 2007 to November 2011,44 patients with atrial myxoma,including 37 cases of Left atrial myxoma,6 cases of Right atrial myxoma,1 case of double atrial myxoma were treated totally under thoracoscope.Surgical procedures were performed through 3 troears inserted at the right chest wall,and catheters were placed in the right femoral artery and vein (or in the right atrium,femoral vein)to set up extracorporeal circulation.The ascending aorta was cross-clamped with long tailor-made forceps and the myocardium was protected by coronary perfusion with cold crystalloid (blood) cardioplegia.ResultsAll the operations were completed successfully.The mean extracorporeal circulation and cross-clamping time were (49 ± 18 )min and (28 ± 10) min respectively.Postoperative ventilation was withdrawn in(3.8 ± 1.4) h,and the patients were discharged from the hospital in (6.8 ± 1.3 ) d.3 of the patients had postoperative complications,including 1 case of fat liquefaction of the incision at the right groin ( delayed healing),2 cases of subcutaneous emphysema ( healed by bandaged chest).No severe complications occurred in this series.UCG performed 3 - 5 days after the operation revealed surgical results were satisfactory.Followup up to 2 months to 4 years were available in all cases.During the period,the heart function was confirmed as level Ⅰ.ConclusionVideo-assisted thoraeoseopie cardiac surgery is feasible,safe,and minimal invasive for patients,resulting in quick recovery and good cosmetic outcomes.

Rabdomiomas cardíacos fetais: análise de cinco casos / Fetal cardiac rhabdomyoma: analysis of five cases

OBJETIVO: analisar o diagnóstico, evolução e conduta terapêutica em cinco casos de tumores cardíacos primários diagnosticados no período pré-natal. MÉTODOS: no período de Janeiro 1997 a Dezembro 2008, 7.989 gestantes foram submetidas à avaliação ultrassonográfica morfológica fetal devido à presença de fatores de risco para malformações fetais. Foram selecionados os casos com massas hipercogênicas intracardíaca maiores que 1 mm diagnosticados na avaliação ultrassonográfica do coração fetal. O diagnóstico diferencial dos tumores foi realizado segundo as características ultrassonográficas das massas. RESULTADOS: em cinco fetos foram diagnosticadas massas hiperecogênicas intracardíaca correspondendo a uma taxa de prevalência de 0,06 por cento. A idade gestacional variou entre a 28ª e a 36ª semanas (média=31) e a idade materna variou de 23 a 45 anos (média=34,2). A localização mais frequente das massas foi o ventrículo esquerdo (100 por cento). Ecograficamente, todas as massas eram hipercogênicas, homogêneas, únicas ou múltiplas e bem delimitadas, compatíveis com diagnóstico de um rabdomioma. Nos casos em que os diâmetros das massas foram menores que 20 mm, a conduta foi expectante e não houve complicações no período pré-natal. Um caso com tumor de grande volume apresentou arritmia e insuficiência cardíaca na 35ª semana de gestação, sendo indicada a interrupção da gestação. Em 80 por cento dos casos foi observada associação com esclerose tuberosa no seguimento pós-natal. A regressão dos tumores cardíacos ocorreu em três casos (60 por cento) durante um seguimento médio de três anos. Todos os recém-nascidos eram do sexo masculino e sem antecedentes familiares de esclerose tuberosa. CONCLUSÕES: a avaliação ultrassonográfica morfológica fetal é a principal forma de detecção precoce dos tumores cardíacos primários. A avaliação cardíaca fetal é fundamental para a caracterização morfológica diferencial das massas cardíacas e para avaliação funcional cardíaca...

PURPOSE: to analyze the differential diagnosis, follow-up and therapeutic approach in five cases of primary cardiac tumors diagnosed during the prenatal period. METHODS: during the period from January 1997 to December 2008, 7989 pregnant women were submitted to morphological ultrasound due to the presence of risk factors for fetal malformations. Fetuses with hyperechogenic intracardiac masses larger than 1 mm diagnosed by ultrasound evaluation of the fetal heart, were selected for study. The differential diagnosis between the different tumor types was made on the basis of the ultrasound characteristics of the masses. RESULTS: five fetuses with hiperechogenic intracardiac masses were diagnosed, corresponding to a 0.06 percent prevalence rate. Gestational age ranged from 28 to 36 weeks (mean: 31), and maternal age ranged from 23 to 45 years (mean: 34,2). The most frequent location of the masses was the left ventricle (100 percent). Echographically, all masses were single or multiple, hyperechogenic, homogeneous and well delimited, compatible with a diagnosis of rhabomyoma. In cases in which the diameters of the masses were less than 20 mm, an expectant conduct was followed and no complications occurred during the prenatal period. One case with a huge tumor presented arrhythmia and cardiac insufficiency during the 35 gestational weeks, and the interruption of pregnancy was indicated. Tuberous sclerosis was associated in four cases (80 percent) and the diagnosis was confirmed during the postnatal follow-up. CONCLUSIONS: fetal morphological ultrasonography is the main form of early detection of primary cardiac tumors. The fetal cardiac evaluation is of fundamental importance for the differential morphological characterization of cardiac masses and for the evaluation of cardiac function. Rhabdomyomas are the most common type of fetal tumor. An expectant pre and postnatal conduct is followed, with a low risk of complications and with the possibility of spontaneous...

Application of circular stapler in the reconstruction of intrathoracic esophagus / 中华消化外科杂志

Objective To review the outeonle of intrathoracic esophageal reconstruction using circular stapler after esophageal or cardiac cancer resection.Methods From June 1996 to April 2007,744 patients underwent tumor removal and intrathoracie esophageal reconstruction in Daping Hospital.Of all patients,658 suffered from thoracic esophageal cancer and the other 86 from cardiac cancer.The operative modalities consisted of gastroesophageal anastomosis at the top of tim thoracic cavity or above the aortic arch in 402 patients,gastroesophageal anastomosis below the aortic arch in 317,and total gastrectomy in 25(esophageal replacement with colon in 21 patients and esophagojejunostomy in 4).Results Anastomotie bleeding oecurred in 5 patients intraoperatively.One patient died of acute respiratory distress syndrome,1 of septic shock and 1 of hepatic failure postoperatively.Psychiatric disorder was observed in 5 patients,respiratory complications in 34,anastomotie fistula in 4,and anastomotic stricture in 20.Three weeks after the operation,the esophageal manometric examination in 25 patients showed that intraesophageal,anastomotie and intragastric pressures were(-0.2±2.0),(1 1.2±4.4)and(2.4±1.5)mm Hg(1 mm Hg=0.133 kPa),respectively.Twenty-four hour pH monitoring demonstrated that 13 patients had abnormal DeMeester score(＞14.72),3 of thenl developed reflux symptoms and got relieved after receiving acid suppression therapy for 1.0-2.2 months.The 13 patients with abnormal DeMeester score were followed up for 3-38 months,and the pH value of the esophagus was back to normal in 2 patients,and it almost remained the same in 9 patients.Two patients died of tumor reculTenee of metastasis.Conclusions Intratlmracic esophageal reconstruction with circular stapler is safe,reliable and able to reduce the postoperative complications such as anastomotic fistula.

Morphological observations of tumors in cardiac conduction system / 老年心脏病学杂志（英文版）

Tumors of the cardiac conduction system (CCS) have rarely been reported. The CCS from 198 cardiac-related deaths (GroupⅠ),and 838 deaths from non-cardiovascular diseases or trauma (Group Ⅱ ), were studied. Sampling was done of the sinoatrial node (SAN)and atrio-ventricular node (AVN) along their long axis of each node as a single block and the His bundle (HB) perpendicular to its long axis in 2-4 blocks. Five-micron serial sections were made; tissue slices were taken intermittently, every 20th from the SAN, every 10th from the AVN, and every 30th from the HB and bundle branches (BB), by continuous slices three times. Tumors in the CCS were found in 12 cases (1.155 %), where 10 (0.965%) were primary tumors, and 2 (0.193%) were metastatic tumors. The primary tumors included 4 fibromata compressing the HB (0.386 %), 4 hemangiomata (0.386%), 1 AVN tumor (0.097 %), and 1 rhabdomyoma (0.097 %). In 8 of the 10 cases, the tumors were located in the AVN or HB. The metastatic tumors originated from lymphocytic leukemia and malignant lymphoma (histiocytic type) in lung, and were all found in the SAN. Of the 12 cases, 2 were from the group Ⅰ. Tumors in the CCS are the smallest tumors in different parts of the body, which can cause sudden death.

Primary Cardiac Osteosarcoma

A 52-year-old woman, who was suffering from aplastic anemia, presented with the clinical features of severe heart failure. The transthoracic echocardiogram showed a heterogeneous, huge mass on the base of the posterior mitral valve. We guessed that the mass would be a benign neoplasm and probably myxoma, and we decided upon surgical resection. After tumor resection, an unexpected result of the histopathology was a high grade osteosarcoma. The other studies that were done after we had the diagnosis could not reveal any evidence of metastatic malignancy.

Radiotherapy of primary cardiac neoplasm / 中华放射肿瘤学杂志

Objective To evaluate the result of radiotherapy for primary cardiac neoplasm.Methods A patients with primary malignant mucinous Schwannoma in th left ventriclular wall had been treated by conservative surgery. He,then,received fast neutron radiotherapy one year after wards. Radiotherapy was given through opposing anterior and posterior fields of 7.8 cm?7.8 cm. The total radiation dose was 1?004.95 ncGy with 11 fractions of 100 ncGy in 48 days.Results The function of the patient's heart recovered after treatment. The patients has been followed for 5 years without evidence of recurrence or distance metastased. Conclusion Fast neutron radiotherapy is effective in the treatment of primary cardiac neoplasms by surgery combined with postoperative radiotherapy. It could improve the prognosis of patients with primary cardiac neoplasms.
