Linfoma cardiaco primario / Primary cardiac lymphoma

Los tumores cardíacos primarios son raros. Tienen una incidencia que varía entre 1,38 y 30 por 100.000 personas al año, un aproximado de 75-80 por ciento son benignos. El linfoma cardíaco primario representa el 1,3 por ciento de los tumores cardíacos primarios y el 0,5 por ciento de los linfomas extranodales. Se define como un linfoma no Hodgkin (LNH) que afecta solo al corazón y/o el pericardio. Su complejo sintomático puede incluir disnea, dolor torácico, fatiga progresiva, sudoración nocturna, pérdida ponderal, arritmias, síndrome de vena cava superior y un aproximado del 20 por ciento de los pacientes pueden desarrollar insuficiencia cardíaca aguda como primera manifestación. Sin embargo, la mayoría de ellos cursan con sintomatología inespecífica y son detectados de manera incidental. El linfoma no Hodgkin difuso de células B grandes es la variante histológica más frecuente. Presentamos un caso que inició con síntomas de insuficiencia cardiaca derecha, evolucionó desfavorable hasta su fallecimiento y se realizó el diagnóstico en la autopsia(AU)

Primary cardiac tumors are rare. They have an incidence that varies between 1.38 and 30 per 100,000 people per year, 75-80 percent are benign, approximately. Primary cardiac lymphoma represents 1.3 percent of primary cardiac tumors and 0.5 percent of extranodal lymphomas. It is defined as a non-Hodgkin's lymphoma (NHL) affecting only the heart and/or the pericardium. Its symptoms may include dyspnea, chest pain, progressive fatigue, night sweats, weight loss, arrhythmias, and superior vena cava syndrome. Approximately 20 percent of patients may develop acute heart failure as the first manifestation. However, most of them have nonspecific symptoms and are detected incidentally. Diffuse large B-cell non-Hodgkin's lymphoma is the most frequent histological variant. We report a case that began with symptoms of right heart failure, progressed unfavorably until death, and the diagnosis was made at autopsy(AU)

Síncope por mixoma auricular: a propósito de un caso clínico / Syncope due to atrial myxoma: presentation of a clinical case / Síncope por mixoma atrial: a propósito de um caso clínico

Las neoplasias cardíacas se dividen en tumores primarios y secundarios; estos últimos son 30 veces más frecuentes. La mayoría de las neoplasias cardíacas son benignas y dentro de este grupo destaca el mixoma auricular. La presentación clínica es muy variable en relación con su ubicación, tamaño y movilidad, y los hallazgos a nivel de las pruebas complementarias son inespecíficos. Dado que su historia natural muchas veces pasa inadvertida, el mixoma puede culminar en la obstrucción auriculoventricular, obstrucción del tracto de salida ventricular o incluso embolias sistémicas; de esta forma, es el causante de sintomatología severa como síncope, insuficiencia cardíaca y muerte súbita cardíaca. Su manifestación clínica como un síncope es bastante frecuente. Se expone el caso de un paciente de sexo masculino de 81 años que consultó en el servicio de urgencias por un síncope. Durante su valoración, se identificó el mixoma auricular como etiología de este.

Cardiac neoplasms are divided into primary and secondary tumors, the latter are 30 times more frequent. Most are benign and within this group the atrial myxoma stands out. The clinical presentation is very variable in relation to its location, size and mobility, and the findings in the complementary tests are nonspecific. Since its natural history often goes unnoticed, the myxoma can culminate in atrial ventricular obstruction, ventricular outflow tract obstruction or even systemic embolism, causing severe symptoms such as syncope, heart failure and sudden cardiac death. Its clinical manifestation as syncope is quite common. The case of an 81-year-old male patient who consulted at the emergency department for syncope is presented, in which the atrial myxoma was subsequently identified as the etiology of the event during the further evaluation.

As neoplasias cardíacas dividem-se em tumores primários e secundários, estes últimos são 30 vezes mais frequentes. A maioria são benignas e dentro deste grupo destaca-se o mixoma auricular. A apresentação clínica é muito variável em relação com sua localização, tamanho e mobilidade, e os achados a nível dos testes complementares são inespecíficos. Dado que a sua história natural muitas vezes passa despercebida, o mixoma pode culminar na obstrução aurículo-ventricular, obstrução do tracto de saída ventricular ou mesmo embolias sistémicas, sendo assim o causador de sintomatologia severa como síncope, insuficiência cardíaca e morte súbita cardíaca. Sua manifestação clínica como síncope é bastante comum. Apresenta-se o caso de um paciente de sexo masculino de 81 anos que consultou no serviço de urgências para um síncope. Durante a sua avaliação, se identificou mixoma auricular como etiologia deste

Mixoma auricular gigante como diagnóstico diferencial de disnea: a propósito de un caso y revisión de la literatura / Giant atrial myxoma as differential diagnosis of dyspnea: a case report and literature review

Cardiac myxomas are the most common benign primary tumors and are most often located in the left atrium at the level of the interatrial septum, with the characteristic of being pedunculated and highly mobile, which is why they sometimes interfere with the functioning of the mitral valve, generating variable degrees of stenosis and mitral insufficiency. Diagnosis is by echocardiography and treatment is surgical resection. We present the case of a patient with a large atrial myxoma and severe double mitral lesion.

Tumores cardíacos pediátricos: características de imagens ecocardiográficas / Pediatric cardiac tumors: echocardiographic imaging features

Tumores cardíacos (TC) em crianças são lesões muito raras, mas seu diagnóstico é fundamental para a conduta adotada para o paciente. A ecocardiografia é a modalidade de imagem cardiovascular mais utilizada na prática clínica para o diagnóstico inicial de TC em pacientes pediátricos. Conhecer as características ecocardiográficas das TCs pode possibilitar um diagnóstico cada vez mais precoce e a identificação de sua etiologia mais provável. Os TCs primários e benignos são os mais frequentes na população pediátrica. Entre os TCs benignos, os mais frequentes em fetos e neonatos são rabdomiomas e teratomas. Em crianças e adolescentes, rabdomiomas e fibromas são os mais comuns. Neste artigo, descrevemos as características ecocardiográficas dos principais TCs em idades pediátricas.(AU)

Cardiac tumors (CTs) in children are very rare, but their diagnosis is crucial for patient management. Echocardiography is the most commonly used cardiovascular imaging modality in clinical practice for the initial diagnosis of CTs in pediatric patients. Knowing the echocardiographic characteristics of CTs can enable an increasingly early diagnosis and the identification of its most likely etiology. Primary and benign CTs are the most frequent types in the pediatric population. Among benign CTs, the most frequent in fetuses and neonates are rhabdomyomas and teratomas. In children and adolescents, rhabdomyomas and fibromas are more common. Here we describe the echocardiographic characteristics of the most common CTs in pediatric patients.(AU)

Acompanhamento a longo prazo de paciente do sexo masculino com fibroma cardíaco assintomático / Long-Term follow-up of an asymptomatic man with a cardiac fibroma

Descreve-se o caso de um homem de 19 anos assintomático com fibroma de ventrículo esquerdo em acompanhamento por 15 anos, sem tratamento.(AU)

Here we describe a case of a 19-year-old asymptomatic man with a left ventricular fibroma on follow-up for 15 years with no treatment required.(AU)

Linfoma cardíaco primário: o papel da multimodalidade de imagem na abordagem diagnóstica / Primary cardiac lymphoma: role of imaging multimodality in diagnosis

Massas intracardíacas constituem um desafio diagnóstico, já que os sintomas são comuns a patologias cardiovasculares ou não. Métodos ­ invasivos ou não ­ possibilitam o diagnóstico diferencial e a confirmação histológica, propiciando tratamento adequado. Para melhor compreender a importância da multimodalidade em imagem e a abordagem nos tumores cardíacos , relatamos o caso de um lifoma cardíaco primário, em que a abordagem multidisciplinar permitiu o rápido diagnóstico e seu tratamento, inclusive das intercorrências, com resposta inicial promissora, a despeito da evolução fatal durante a pandemia por SARS-CoV-2.(AU)

Intracardiac masses are a diagnostic challenge since their symptoms can be common to cardiovascular pathologies. Some methods, whether invasive or not, enable differential diagnosis, histological confirmation, and adequate treatment. To better understand the importance of imaging multimodality and the approach to managing cardiac tumors, we investigated a case of a primary cardiac lymphoma in which the multidisciplinary approach allowed rapid diagnosis and treatment, including of intercurrences, with a promising initial response despite fatal progression due to severe acute respiratory syndrome coronavirus 2 infection.

Fast growth rate of a right atrial myxoma

ABSTRACT Primary cardiac tumors are rare, with an incidence between 0.0017 and 0.19%, and are asymptomatic in up to 72% of cases. Approximately 75% of tumors are benign, and nearly 50% of these are myxomas. Concerning location, 75% of myxomas are in the left atrium, 15 to 20% in the right atrium, and more rarely in the ventricles. The finding of cardiac myxomas usually implies immediate surgical excision to prevent embolic events and sudden cardiac death. Reports with documented growth rate are rare, and the actual growth rate remains a controversial issue. We report the rapid growth rate of a right atrial myxoma in an oligosymptomatic 69-year-old patient, with negative previous echocardiographic history in the last two years, who refused surgery upon diagnosis, enabling monitoring of myxoma growth.

Ultrasonographic features of cutaneous myxomas in a patient with Carney complex

Abstract Carney complex is a rare genodermatosis characterized by cardiac and cutaneous myxomas, among other tumors. In the majority of cases, cutaneous myxomas precede the diagnosis of cardiac myxomas, which are the main cause of death in these patients. Despite the fact that the diagnosis of cutaneous myxomas is histopathological, high-frequency ultrasonography plays an essential role in the differential diagnosis with other cutaneous and subcutaneous tumors. The authors of the present study describe, for the first time in the literature, the ultrasonographic features of both variants of cutaneous myxomas, superficial and subcutaneous, in a patient with a Carney complex.

Cardiac Masses: Pathological and Surgical Features - A Multicenter Study

Abstract Introduction: This study aimed to review the surgical excision results and pathological diagnostic features of rarely observed intracardiac masses in the light of the literature. Diagnosis and treatment approaches and complications were evaluated. Methods: Forty patients (26 females, mean age 52.1±18.1 years, and 14 males, mean age 48.1±20.5 years), who had undergone surgery for intracardiac mass between January 2008 and December 2018, were included in this study. The patients' data were analyzed retrospectively from the medical records of both centers. Results: When the pathological diagnoses were examined, 85.8% of the masses (n=35) were observed to be benign (benign tumor + hydatid cyst) and 14.2% (n=5) were malignant tumors. The masses were most commonly located in the left atrium (75%, n=30), and this was followed by the right ventricle (12.5%, n=5), right atrium (7.5%, n=3), and left ventricle (5%, n=2). Of the patients, 7.5% (n=3) died during the early postoperative period, while the remaining 92.5% (n=37) were discharged with healing. In the histopathological diagnosis of the patients, in whom in-hospital major adverse cardiovascular events were observed, there was malignancy in two cases. Conclusion: Intracardiac masses, which have pathological features, are severe life-threatening problems. In-hospital mortality is frequent, especially in malignant tumors.

Metástasis cardíaca de carcinoma anaplásico de tiroides / Cardiac metastasis from primary anaplastic thyroid carcinoma

Resumen Las neoplasias cardíacas son entidades poco frecuentes en la práctica clínica cardiológica y dentro de éstas, la afectación metastásica es 20 a 40 veces más frecuente que la forma primaria, corres pondiendo al 95% de todos los tumores cardíacos; no obstante, debido a las características clínicas y oncológicas del tumor primario, los tumores cardíacos metastásicos son habitualmente subdiagnosticados. En este trabajo se presentan dos casos de pacientes con carcinoma anaplásico de tiroides, una mujer de 69 años con metástasis en ventrículo derecho y un varón de 61 años con metástasis en aurícula derecha. Ambos pacientes fallecieron durante la internación y a uno de ellos se le realizó autopsia.

Abstract Cardiac neoplasms are rare entities in the clinical practice. Cardiac metastatic involvement is 20 to 40 times more frequent than the primary form, representing 95% of all cardiac tumors; however, they are frequently underdiagnosed because of their clinical and oncologic features. In this report, we present two cases of cardiac metastasis from primary anaplastic thyroid carcinoma: a 69-years-old woman with right ventricular metastasis and a 61-years-old man with right atrial metastasis. Both patients died during their hospitalization and one of them underwent an autopsy.

Insuficiencia cardíaca como presentación de sarcoma cardíaco: caso clínico y revisión de la literatura / Cardiac sarcoma associated to heart failure: case report and review

The clinical case of a patient presenting with heart failure with unclear etiology is presented. Clinical and laboratory findings are described along with the results of imaging studies. Findings at the time of surgery and histopathological characteristics are illustrated. A review of the literature is included.

Rabdomiosarcoma alveolar con metástasis cardíaca en un paciente pediátrico / Alveolar rhabdomyosarcoma with cardiac metastasis in a pediatric patient

El rabdomiosarcoma es el tumor maligno de partes blandas más frecuente en la edad pediátrica. Puede afectar cualquier localización anatómica. El subtipo histológico alveolar suele causar lesiones en las extremidades en niños de mayor edad. Los sitios metástasicos más frecuentes son el pulmón, la médula ósea, el hueso y los ganglios linfáticos. Describimos el caso de un paciente con rabdomiosarcoma alveolar (RA) con metástasis cardíaca, una presentación poco frecuente de la patología.

Rhabdomyosarcoma is the most common malignant soft tissue tumor in pediatric age. It can affect any anatomical location. Alveolar histological subtype usually presents lesions on the extremities in older children. The most common metastatic sites are the lung, bone marrow, bone and lymph node. We describe a case of alveolar rhabdomyosarcoma with cardiac metastasis in a pediatric patient, a rare presentation of the pathology.

Multidisciplinary approach to right ventricular myxoma

Abstract Right ventricular (RV) myxoma that obstructs the RV outflow tract is rare. Multimodality imaging is crucial due to the curved and triangular shape of the RV anatomy. Incomplete resection by the right atrial approach in cardiac myxomas may be prevented by preoperative imaging with echocardiography, computed tomography and magnetic resonance imaging to provide detailed visualization. Right ventriculotomy may be an alternative approach to the isolated atrial approach to get complete resection of RV myxoma in suitable patients. The preferred surgical treatment is not well defined for ventricular myxomas and careful preoperative planning is essential. Surgical resection should be performed as soon as possible to avoid outflow tract obstruction, which might result in sudden death. The collaboration between cardiologist and heart surgeon and the effective use of imaging tools are essential for successful treatment. In this article, diagnosis and treatment and the heart team approach to RV myxoma are discussed with a demonstrative patient.

Linfoma pericárdico primario a células T/NK: reporte de un caso / Primary pericardial T/NK cell lymphoma: case report / Linfoma pericárdico primário de células T/NK: relato de um caso

Los linfomas cardíacos primarios son un subtipo muy poco frecuente de tumor en los cuales la lesión primaria se encuentra en el corazón. Los tumores suelen ser infiltrantes y se localizan en la aurícula derecha, seguidos del pericardio. Su mortalidad es notablemente alta y el diagnóstico tardío es el principal factor para su mal pronóstico. Describimos el caso de un paciente que presentó shock obstructivo por derrame pericárdico profuso causado por un tipo raro de tumor cardíaco primario, un linfoma pericárdico de células T/NK.

Primary cardiac lymphomas are a rare subtype of lymphomas in which the primary lesion is in the heart. The tumors are usually located in the right atria, followed by the pericardium and are frequently infiltrative. Mortality is remarkably high in this group and the delayed diagnosis is the main factor for its poor prognosis. We describe the case of a patient that presented with obstructive shock due to profuse pericardial effuse caused by a rare kind of primary cardiac tumor, a T/NK cell pericardial lymphoma.

Os linfomas cardíacos primários são um subtipo de tumor muito raro, no qual a lesão primária está no coração. Os tumores geralmente são infiltrativos e localizam-se no átrio direito, seguidos pelo pericárdio. Sua mortalidade é notavelmente alta e o diagnóstico tardio é o principal fator que produz seu mau prognóstico. Descrevemos o caso de um paciente que apresentou choque obstrutivo devido a um derrame pericárdico profuso causado por um tipo raro de tumor cardíaco primário, um linfoma pericárdico de células T/NK.

Resumen Introducción: Los rabdomiomas son los tumores cardiacos benignos más prevalentes en la etapa fetal y durante la infancia. Objetivo: Nuestro objetivo es dar a conocer nuestra experiencia durante 39 años en pacientes pediátricos con rabdomioma en nuestra institución, así como enfatizar la importancia de su detección, estudio y control por la asociación que tiene con esclerosis tuberosa (ET). Material y métodos: Realizamos un estudio retrospectivo y descriptivo, de enero de 1980 a marzo del 2018. Veinticuatro cumplieron con nuestros criterios, recogimos información respecto a la clínica y estudios de gabinete, así como su evolución y el tratamiento dado. Se les llamó vía telefónica para conocer su evolución y estado actual. Resultados: Encontramos 51 pacientes con diagnóstico de tumor cardiaco, de los cuales 24 eran rabdomiomas. El diagnóstico se hizo prenatal en 8 pacientes, 5 al nacimiento y en 11 durante el primer año de vida. Las manifestaciones clínicas más frecuentes fueron la presencia de soplo, arritmias, cianosis, disnea y diaforesis. En 17 de ellos se hizo diagnóstico de ET. La mitad tuvo seguimiento por neurología, 10 por dermatología, 8 por oftalmología y 4 con genética. La mitad se dejó en vigilancia, a 7 se les dio tratamiento médico y 5 requirieron cirugía. En cuanto a la evolución, 17 pacientes se mantuvieron estables, 5 presentaron regresión espontánea y 2 fallecieron. Conclusiones: El rabdomioma es un tumor benigno poco frecuente, su evolución puede ser maligna y asociado a ET ensombrece el pronóstico.

Abstract Introduction: Rhabdomyomas are the most prevalent benign heart tumors in the fetal stage and during childhood. Objective: Our objective is to make known our experience over 39 years in pediatric patients with rhabdomyoma in our institution, as well as to emphasize the importance of its detection, study and control due to the association it has with tuberous sclerosis (TS). Material and methods: We conducted a retrospective, descriptive and cross-sectional study, from January 1980 to March 2018. Twenty-four met our criteria, we collected information regarding the clinic and cabinet studies, as well as their evolution and the treatment given. They were called by telephone to know their evolution and current status. Results: We found 51 patients with a diagnosis of cardiac tumor, of which 24 were rhabdomyomas. The diagnosis was made prenatal in 8 patients, 5 at birth and in 11 during the first year of life. The most frequent clinical manifestations were the presence of murmur, arrhythmias, cyanosis, dyspnea, and diaphoresis. In 17 of them a diagnosis of TS was made. Half had follow-up by neurology, 10 by dermatology, 8 by ophthalmology and 4 with genetics. Half were left under surveillance, 7 were given medical treatment and 5 required surgery. Regarding the clinical evolution 17 patients remained stable, 5 presented spontaneous regression and 2 died. Conclusions: Rhabdomyoma is a rare benign tumor, its evolution can be malignant and associated with TS, it darkens the prognosis.

The current role of surgery in the treatment of cardiac metastases from malignant melanoma: an educational presentation

Abstract A 71 year-old male with a history of multiple excisions of an initial Clark's level V melanoma of the breast followed by combined radiation and interferon treatment, as well as a recurrence, 3 years later, of a BRAF-positive tumor of the shoulder, with subsequent therapy with dabrafenib and trametinib, presented again with progressive intracardiac masses causing significant right ventricular outflow obstruction. Additionally, the patient complained of dyspnea and fatigue on exertion, thus he was scheduled for surgical resection.

Clinical and imaging characteristics of patients with primary cardiac angiosarcoma / 中华心血管病杂志

Objective: To investigate the clinical, cardiac imaging characteristics and prognosis of patients with primary cardiac angiosarcoma. Methods: The clinical data of 14 patients hospitalized with primary cardiac angiosarcoma from January 2001 to December 2017 in Peking Union Medical College Hospital were collected and analyzed. Metastatic cardiac angiosarcoma was not included in this study. Patients were followed up post discharge per telephone call or clinical visit. Results: Of the 14 patients, 8 were males and 6 were females, average age was 48 years. The main clinical symptoms were shortness of breath (8/14), hemoptysis (6/14), fever (5/14), chest pain (4/14) and cough (3/14). Imaging examinations showed that the tumors of 8 patients were located in the right heart and 6 in the pericardial cavity. Tumors in the right heart often infiltrate the atrial wall and cause pericardial effusion (7/8). Tumors in the pericardium were characterized by recurrent bloody pericardial effusion (6/6), prone to progressive constrictive pericarditis (3/6), pericardial fluid cytology was often negative (6/6). MRI showed heterogeneous high signal intensity (cauliflower aspect) on T2-weighted image and heterogeneous enhancement with a"sunray" aspect at the perfusion study. At the time of diagnosis, 8 patients developed lung or adrenal metastasis (8/14). The median survival was only 305 days. Conclusions: Primary cardiac angiosarcoma is a rare disease with non-specific clinical manifestation and poor prognosis. Imaging examinations may help diagnosis. The high invasiveness and the easy-to-metastasis feature of the tumor contribute to the poor prognosis of cardiac angiosarcoma.
