Resumen: Los tumores cardíacos pueden ser primarios o, más frecuentemente secundarios o metastásicos. Entre los tumores primarios es más frecuente el mixoma, cuya ubicación más común es en la aurícula izquierda. Las manifestaciones clínicas son diversas, producidas principalmente por obstrucción mecánica, embolizaciones, y manifestaciones constitucionales. Se comunica el caso de un paciente de 32 años, con cuadro clínico de insuficiencia cardíaca, hipertensión pulmonar severa y tromboembolismo pulmonar bilateral. Se hizo el diagnóstico de mixoma auricular izquierdo. Se resecó el tumor y se manejó la hipertensión pulmonar desde el ingreso al hospital con inhibidores de la fosfodiesterasa asociado a anticoagulación. Se discute el tema dando énfasis a aspectos fisiopatológicos involucrados tanto en la hipertensión pulmonar como en la presencia de tromboembolia pulmonar.
Abstract: Cardiac tumors may be primary or, more frequently secondary or associated to metastasis. Atril myxoma es the most frequent primary tumor, usually located in the left atrium. Clinical manifestations include those due to mitral valve occlusión, emboli and general non spedific symptoms and signs. Herein we report the clinical case of a 32 year old patient with severe pulmonary hypertension and bilateral pulmonary embolism. The tumor was extirpated, and he received phosphoro-diesterase inhiborts and anticoagulants. Subsequent clinical course was satisfactory. A brief discussion of this condicion is included.

BACKGROUND: Atrial myxomas are very infrequent primary bening cardiac neoplasms, being considered a rare but highly fatal cause of cerebral embolism. Objectives: We describe the case of an ischemic stroke (CVA) with hemorrhagic conversion secondary to atrila myxoma as an embolic source, and its subsequent early surgical resolution. CLINICAL CASE: A 63-year-old male has a clinical episode compatible with ischemic stroke, receiving thrombolytics treatment with subsequent hemorrhagic conversion. Embolic source study show a mass compatible with cardiac myxoma in the left atrium, performing surgical resection via transeptal approach at 12 days of evolution, with repair of the interatrial defect with autologous pericardium patch. DISCUSSION: Atrial myxoma is a silent pathology and little diagnosed at its early stage, associated with events of systemic repercussion of high mortality and uncertain prognosis. Hemorrhagic cerebrovascular events constitute contraindication for anticoagulation prior to 21 days of evolution. In this case, due to the high embolic risk of myxoma, the inactivy of the bleeding was demonstrated by performing the surgery successfully on the twelfth day of evolution.

El angiomixoma de la pelvis es un tumor mesenquimal inusual; que dado su alto potencial de recidiva es relevante que la exéresis quirúrgica sea lo más radical posible. Por su parte, la endometriosis infiltrativa profunda, es otra entidad poco frecuente que requiere de tratamientos complejos. La co-existencia de ambas patologías representa una situación absolutamente infrecuente; de los que hay muy pocos casos reportado en la literatura occidental. Se presenta el caso de una mujer de 41 años de edad que desarrolló ambas entidades nosológicas de forma concomitante y que fue tratada quirúrgicamente con buenos resultados.
Angiomyxoma of the pelvis is an unusual mesenchymal tumor; that given its high potential for recurrence, it is relevant that the surgical resection be as radical as possible. For its part, to deep infiltrative endometriosis is another rare entity that requires complex treatments. The co-existence of both pathologies represents an absolutely infrequent situation; of which there are very few cases reported in western literature. We present the case of a 41-year-old woman who developed both clinical entities concomitantly and who was treated surgically with good results.

SUMMARY Cardiac myxoma is a benign neoplasm, which corresponds to the most common primary heart tumour, responsible for about 50% of the cases. In general, 75-80% of myxomas are located in the left atrium, 18% in the right atrium, and more rarely in the ventricles or multicentric. Right atrial myxoma, in particular, can obstruct the tricuspid valve, causing symptoms of right heart failure, peripheral oedema, hepatic congestion, and syncope. Systemic embolization occurs in 30% of cases, by either tumour fragmentation or total tumour detachment. In the present report, we present a case of a symptomatic patient, who showed a large right intra-atrial lesion, with consequent superior vena cava syndrome, and then underwent surgical resection at admission.
RESUMO O mixoma cardíaco é uma neoplasia benigna, que corresponde ao tumor primário mais comum do coração, responsável por cerca de 50% dos casos. De modo geral, 75 a 80% dos mixomas estão localizados no átrio esquerdo, 18% no átrio direito, e mais raramente, nos ventrículos ou multicêntricos. O mixoma atrial direito, em particular, pode obstruir a válvula tricúspide, causando sintomas de insuficiência cardíaca direita, edema periférico, congestão hepática e síncope. A embolização sistêmica ocorre em 30% dos casos, quer pela fragmentação do tumor ou pelo desprendimento total do mesmo. No presente relato, apresentamos um caso de uma paciente sintomática, que evidenciou grande lesão intra-atrial direita, com consequente síndrome da veia cava superior, sendo, então, submetida a ressecção cirúrgica na internação.

We report a 23-year-old woman, with three recent exertional syncopes. Transthoracic (TTE) and transesophageal (TEE) echocardiography found a large heterogeneous mass (38 x 35 mm) arising from the posterior mitral annulus, protruding in systole through the left ventricular outflow tract (LVOT). Heart MRI confirmed the echocardiography findings, suggesting a cardiac myxoma. Cardiac surgery accomplished the complete resection of the lesion, confirming a mass arising from the posterior mitral annulus and preserving mitral anatomy and function. Pathology was positive for a myxoma. Uneventful evolution allowed the discharge of the patient at the fifth postoperative day. Control TTE discarded any complication.

Abstract Objective: The clinical features of cardiac myxoma stroke have not been sufficiently described. Debates remain concerning the options and timing of treatment and the clinical outcomes are unknown. This article aims to highlight the pertinent aspects of this rare condition. Methods: Data source of the present study came from a comprehensive literature collection of cardiac myxoma stroke in PubMed, Google search engine and Highwire Press for the year range 2000-2014. Results: Young adults, female predominance, single cerebral vessel (mostly the middle cerebral artery), multiple territory involvements and solitary left atrial myxoma constituted the outstanding characteristics of this patient setting. The most common affected cerebral vessel (the middle cerebral artery) and areas (the basal ganglion, cerebellum and parietal and temporal regions) corresponded well to the common manifestations of this patient setting, such as conscious alteration, ataxia, hemiparesis and hemiplegia, aphasia and dysarthria. Initial computed tomography scan carried a higher false negative rate for the diagnosis of cerebral infarction than magnetic resonance imaging did. A delayed surgical resection of cardiac myxoma was associated with an increased risk of potential consequences in particular otherwise arterial embolism. The mortality rate of this patient population was 15.3%. Conclusion: Cardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct. .
Resumo Objetivo: As características clínicas do acidente vascular cerebral causado por mixoma cardíaco não foram descritas suficientemente. Debates permanecem sobre as opções e o momento de tratamento e os resultados clínicos são desconhecidos. Este artigo tem como objetivo destacar os aspectos pertinentes desta condição rara. Métodos: Os dados do presente estudo foram levantados em uma revisão abrangente de literatura sobre acidente vascular cerebral causado por mixoma cardíaco no PubMed, no sistema de buscas do Google e no Highwire Press, abrangendo ao anos entre 2000 e 2014. Resultados: Adultos jovens, predominância do sexo feminino, vaso cerebral único (principalmente a artéria cerebral mediana), envolvimentos de territórios múltiplos e mixoma atrial esquerdo solitário são características marcantes destes pacientes. O vaso cerebral afetado mais comum (artéria cerebral média) e áreas (o gânglio basal, cerebelo e regiões parietais e temporais) corresponderam bem com as manifestações comuns destes pacientes, como alteração da consciência, ataxia, hemiparesia e hemiplegia, afasia e disartria. Tomografia computadorizada inicial mostrou taxa de falso negativo mais alta para o diagnóstico de acidente vascular cerebral do que a imagem por ressonância magnética. A ressecção cirúrgica tardia de mixoma cardíaco foi associada com risco aumentado de potenciais consequências, em particular, de outra forma de embolia arterial. A taxa de mortalidade dessa população de pacientes foi de 15,3%. Conclusão: Acidente vascular cerebral causado por mixoma cardíaco é raro. Frequentemente, afeta mulheres jovens. Para um diagnóstico mais preciso, exames de ressonância magnética e ecocardiográficos são imperativos para pacientes jovens com acidente vascular cerebral para determinar a localização do enfarte cerebral e se houve origem cardíaca. Terapia trombolítica imediata pode resolver completamente o acidente vascular cerebral e melhorar a função neurológica ...

Background: Cardiac tumors are rare, mostly benign with high embolic potential. Objectives: To correlate the histological type of cardiac masses with their embolic potential, implantation site and long term follow up in patients undergoing surgery. Methods: Between January 1986 and December 2011, we retrospectively analyzed 185 consecutive patients who underwent excision of intracardiac mass (119 females, mean age 48±20 years). In 145 patients, the left atrium was the origin site. 72% were asymptomatic and prior embolization was often observed (19.8%). The diagnosis was established by echocardiography, magnetic resonance and histological examination. Results: Most tumors were located in the left side of the heart. Myxoma was the most common (72.6%), followed by fibromas (6.9%), thrombi (6.4%) and sarcomas (6.4%). Ranging from 0.6cm to 15cm (mean 4.6 ± 2.5cm) 37 (19.8%) patients had prior embolization, stroke 10.2%, coronary 4.8%, peripheral 4.3% 5.4% of hospital death, with a predominance of malignant tumors (40% p < 0.0001). The histological type was a predictor of mortality (rhabdomyomas and sarcomas p = 0.002) and embolic event (sarcoma, lipoma and fibroelastoma p = 0.006), but not recurrence. Tumor size, atrial fibrillation, cavity and valve impairment were not associated with the embolic event. During follow-up (mean 80±63 months), there were 2 deaths (1.1%) and two recurrences 1 and 11 years after the operation, to the same cavity. Conclusion: Most tumors were located in the left side of the heart. The histological type was predictor of death and preoperative embolic event, while the implantation site carries no relation with mortality or to embolic event. .
Fundamento: Os tumores do coração são infrequentes, em sua maioria benignos e com alto potencial embólico. Objetivo: Correlacionar o tipo histológico do tumor cardíaco com seu potencial embólico, com o sítio de implantação e analisar a evolução tardia destes pacientes submetidos à cirurgia. Métodos: No período de dezembro de 1986 a setembro de 2011 foram retrospectivamente analisados 186 pacientes operados (119 do sexo feminino e idade média de 48 ± 20 anos). Foram 145 tumores de átrio esquerdo (77%), 72% dos pacientes assintomáticos e 19,8% com embolização prévia. O diagnóstico foi confirmado por ecocardiograma, ressonância magnética e exame histológico. Resultados: A maioria dos tumores situava-se nas câmaras esquerdas. O mixoma foi o mais frequente (72,6%), seguido dos fibromas (6,9%), trombos (6,4%) e sarcomas (6,4%). Seus tamanhos variaram de 0,6cm a 15 cm (média de 4,6 ± 2,5cm). Houve 37 embolizações prévias à operação (10,2% AVC, 4,8% IAM e 4,3% periférica). Foram 5,4% de óbito hospitalar, com predomínio nos tumores malignos (40% p < 0,0001). O tipo histológico foi preditor de mortalidade (rabdomioma e sarcomas p = 0,002) e de evento embólico (sarcomas, fibroelastoma e lipoma p = 0,006), porém não de recidiva. O tamanho tumoral, a fibrilação atrial, a cavidade e valva acometida não apresentaram relação com o evento embólico. Durante o seguimento (média de 80 ± 63 meses), houve 2 óbitos (1,1%) e duas recidivas tumorais 1 e 11 anos após a operação, ambas para a mesma cavidade. Conclusão: O tipo histológico foi preditor de óbito e de evento embólico pré-operatório, enquanto o sítio de implantação não. .

Mitral regurgitation is uncommon with left atrial myxoma. The echocardiographic assessment of presence of mitral regurgitation and its severity are impaired by the presence of left atrial myxoma. We describe an uncommon association of left atrial myxoma with coronary artery disease and mitral regurgitation. MR was reported as mild on pre‑operative transthoracic echocardiography but found to be severe due to ruptured chordae tendinae during intra‑operative transesophageal echocardiography, which lead to change in the surgical plan to mitral valve replacement in addition to excision of myxoma.

Os mixomas são os tumores cardíacos primários benignos mais comuns, sendo que a grande maioria localiza-se no átrio esquerdo; 80 por cento têm sua origem no septo interatrial e 5 por cento deles são biatrial. Clinicamente, apresentam-se, quase sempre, com sinais e sintomas de doença valvular mitral ou de eventos tromboembólicos. Este relato ilustra um caso de mixoma em átrio esquerdo, projetando-se através da valva mitral para o ventrículo esquerdo e simulando uma estenose mitral, que evoluiu com acidente vascular cerebral isquêmico (AVCi) e infarto agudo do miocárdio (IAM), como complicações tromboembólicas. O ecocardiograma continua a ser uma ferramenta valiosa no diagnóstico e o tratamento cirúrgico imediato é necessário para evitar desfechos fatais.
Myxomas are the most common benign primary cardiac tumors, the vast majority located in the left atrium and 80 percent originates in the atrial septum and 5 percent of them are biatrial.Usually present, often with signs and symptoms of mitral valve disease or thromboembolic events. This report illustrates a case of myxoma in left atrium protrudind through the mitral valve into the left ventricle, simulating stenotic mitral valve disease, which evolved with ischemic stroke (AIS) and acute myocardial infarction (MI) as thromboembolic events. Echocardiography continues to be a valuable tool in the diagnosis and surgical treatment is immediately necessary to prevent fatal outcomes.
Los mixomas son los tumores cardíacos primarios benignos más comunes, siendo que la gran mayoría se localiza en la aurícula izquierda; el 80% tiene su origen en el septo interauricular y el 5% de ellos son biauriculares. Clínicamente, se presentan, casi siempre, con señales y síntomas de enfermedad valvular mitral o de eventos tromboembólicos. Este relato ilustra un caso de mixoma en aurícula izquierda, proyectándose a través de la válvula mitral hacia el ventrículo izquierdo y simulando una estenosis mitral, que evolucionó con accidente vascular cerebral isquémico (AVCi) e infarto agudo del miocardio (IAM), con complicaciones tromboembólicas. El ecocardiograma continua siendo una herramienta valiosa en el diagnóstico y el tratamiento quirúrgico inmediato es necesario para evitar desenlaces fatales.

Although the association between right atrial myxoma and pulmonary embolism is rare, it has been recognized for many years. This condition is fatal unless surgical intervention is performed for resection of right atrial mass and pulmonary embolectomy. A 68 years old diabetic, hypertensive male patient was admitted to our hospital with severedy spnea and chest pain. An echocardiogram and pulmonary CT angiography revealed right atrial mass and pulmonary embolism. Further more, coronary angiography was done and showed a three vessels disease. Complete surgical removal of the right atrial myxoma and parts of the tumor embolectomy from the right pulmonary artery were successfully performed combined with coronary artery bypass grafting to LAD, obtuse marginal and diagonal branches. Histological examination of the primary tumor as well as the embolus confirmed the diagnosis of benign myxoma. The patientwas discharged after 15 days of his successful operation. We report this case, as it is unique because of the rarity of the combined surgery of right atrial myxoma complicated with pulmonary embolism and coronary artery bypass grafting.
Si bien la asociación entre el mixoma auricular derecho y la embolia pulmonar es poco frecuente, se conoce su existencia desde hace años. La condición es fatal salvo si se realiza una intervención quirúrgica para la resección de la masa auricular derecha y una embolectomía pulmonar. Ingresa a nuestro hospital un paciente masculino diabético e hipertenso de 68 años con disnea severa y dolor de pecho. Un ecocardiograma y una angioTac de pulmón revelan un masa auricularderecha y una embolia pulmonar. Además, la coronario angiografia realizada identifica enfermedad en tres vasos. Se realiza con éxito la resección quirúrgica completa del mixoma auricular derecho y parte de la embolectomia tumoral de la arteria pulmonar derecha junto con un bypass de la arteria coronaria a la descendente anterior, la marginal obtusa y las ramas diagonales. El examen histopatológico del tumor primario y de la embolia confirman el diagnóstico de mixoma benigno. El paciente fue dado de alta 15 días después de la exitosa operación. Publicamos este caso ya que es único porque es poco frecuente es combinar la cirugía de un mixoma auricular derecho complicado por una embolia pulmonar con una cirugía de bypass de la arteria coronaria.

A condição é fatal salvo se realizamos uma intervenção cirúrgica para a resecção da massa auricular direita e uma embolectomia pulmonar. Ingressa ao nosso hospital um paciente masculino diabético e hipertenso de 68 anos com dispnéia severa e dor no peito. Um ecocardiograma e um angioTAC do pulmão revelam uma massa auricular direita e uma embolia pulmonar. Além disso, a coronario angiografia realizada identifica comprometimento de três vasos. Realiza-se com êxito a resecção cirúrgica completa do mixoma auricular direito e parte da embolectomia tumoral da artéria pulmonar direita junto com um bypass da artéria coronária àdescendente anterior, a artéria obtusa marginal e os ramos diagonais. O exame histopatológico do tumor primário e da embolia confirmam o diagnóstico de mixoma benigno. O paciente recebeu alta 15 dias depois da exitosa operação. Publicamos este caso por ser único devido à pouco frequência em combinar a cirurgia de um mixoma auricular direito complicado por uma embolia pulmonar com uma cirurgia de bypass da artéria coronária.
