Título: Mixoma auricular izquierdo como causa de accidente cerebral isquémico transitorio e infarto agudo de miocardio con elevación del ST / Left atrial myxoma as a cause of a transient ischaemic stroke and acute myocardial infarction with ST elevation
Fonte: Rev. colomb. cardiol;27(6):602-606, nov.-dic. 2020. graf.
Idioma: es.
Resumo: Resumen Los mixomas son los tumores cardíacos primarios más comunes. La mayoría tiene curso benigno y pueden tratarse de hallazgos incidentales o ser casi asintomáticos. Los síntomas dependen de su ubicación, en cuyo caso la más frecuente es la aurícula izquierda, de ahí que el riesgo embólico sea elevado. El principal lugar de embolia es el sistema nervioso central; sin embargo, en ocasiones puede afectar los sistemas respiratorio, periférico o coronario(1). Se expone el caso de una paciente con mixoma auricular izquierdo, el cual se manifiesta con accidente cerebral isquémico transitorio, seguido de infarto agudo de miocardio con elevación del segmento ST en la pared ínfero-posterior.

Abstract The myxomas are the most common primary cardiac tumours. The majority of them are benign and can be an incidental finding or be almost asymptomatic. The symptoms depend on their location, with the most common being the left atrium, which carries an increased risk of clots. The main effects of the clots are on the central nervous system, but occasionally they can involve the respiratory, peripheral, or coronary system. The case is presented of a patient with left atrial myxoma, as well as a transient ischaemic stroke and acute myocardial infarction with ST elevation in the inferior-posterior wall.

Título: Masa auricular derecha: la importancia del ecocardiograma al momento del diagnóstico de fibrilación auricular en el enfoque terapéutico / Right atrial mass: The importance of cardiac ultrasound at the time of diagnosis of atrial fibrillation in the therapeutic approach
Fonte: Rev. colomb. cardiol;27(6):607-610, nov.-dic. 2020. graf.
Idioma: es.
Resumo: Resumen Se presenta el caso de un varón de 70 años de edad, quien debutó con fibrilación auricular no valvular, en quien, dos meses después y mediante ecocardiografía, se objetivaron dos masas contiguas en la aurícula derecha. Las masas eran dependientes de la válvula de Eustaquio, alcanzaban el septo interauricular y se asemejaban a un mixoma. Ambas fueron resecadas mediante cirugía, sin complicaciones intraoperatorias ni postoperatorias. El estudio anatomo-patológico concluyó que eran compatibles con trombos sin componente tumoral. Durante el seguimiento permaneció asintomático y en ritmo de fibrilación auricular.

Abstract The case is presented on a 70 year-old male who debuted with non-valvular atrial fibrillation. Two months later, and using cardiac ultrasound, two contiguous masses were observed in the right atrium. The masses were hanging from the Eustachian (inferior vena cave) valve, reached the interatrial septum and resembled a myxoma. Both were surgically resected, with no intra- or post-operative complications. The patient remained asymptomatic and in atrial fibrillation rhythm during follow-up.

Título: Mixoma auricular derecho en la infancia / Right atrium myxoma in chilhood
Fonte: Gac. méd. boliv;43(1):103-106, ago. 2020. ilus.
Idioma: es.
Resumo: Los tumores cardíacos primarios son poco frecuentes y representan solo el 5% de todos los tumores cardíacos. El 75% de estos tumores son benignos, y el mixoma es el tumor benigno más común en el adulto (50%). La mayoría de los mixomas cardíacos se localizan en la aurícula izquierda, solo el 18-20% se localizan en la aurícula derecha, y es aún más infrecuente la aparición de un tumor bilobulado, los signos y síntomas con los que se presentan son inespecíficos y varían de acuerdo a su comportamiento. Presentamos un caso con estas características en una paciente escolar de 9 años de edad que ingresó al Hospital del Niño Manuel Ascencio Villarroel

Primary cardiac tumors are rare and represent only 5% of all cardiac tumors. 75% of these tumors are benign, and myxoma is the most common benign tumor in adults (50%). Most cardiac myxomas are located in the left atrium, only 18-20% are located in the right atrium, and the appearance of a bilobed tumor is even more infrequent, the signs and symptoms with which they occur are nonspecific and they vary according to their behavior. We present a case with these characteristics in a 9-year-old school patient who was admitted to Manuel Ascencio Villarroel Children's Hospital.

Título: Mixoma odontogénico / Odontogenic myxoma
Fonte: Rev. cuba. estomatol;46(3), jul.-sept. 2009. ilus.
Idioma: es.
Resumo: El mixoma odontogénico se considera una neoplasia benigna, poco frecuente, de consistencia firme y gelatinosa, de crecimiento lento con potencial infiltrativo que produce expansión de la cortical con extensa destrucción ósea y alto índice de recidiva. De origen ectomesenquimàtico, probablemente derivado del órgano dentario. No existe una predilección particular por sexo, y si una ligera preferencia por presentarse en mandíbula, generalmente asintomàtico. Se presenta una paciente femenina de dieciséis años de edad, color de la piel blanca, con antecedentes de salud, que acude a consulta de cirugía màxilo facial por aumento de volumen de hemicara derecha, sin otra sintomatología acompañante. Al examen físico se observa aumento de volumen en región maxilar derecha. Al realizar tomografía axial computarizada se observó lesión hiperdensa que ocupaba todo el seno maxilar derecho, con àreas de mayor densidad, que respetaba el hueso que conforma el piso de la órbita. Bajo anestesia general naso traqueal se le realizó hemimaxilectomia, retirada de tumor y colocación de prótesis inmediata obturadora. Después de un año de evolución clínica y radiogràfica se colocó la prótesis definitiva, sin presencia de recidiva tumoral(AU)

An odontogenic myxoma is a uncommon benign neoplasm of a gelatinous and solid consistency, of lengthy growing with a infiltration potential producing an cortex expansion of with and extend bone destruction and a high rate of relapse. Its origin is ectomesenchymal, probably derived from dental organ. There is not a particular sexual preference, but a slight one by be present in mandible and generally asymptomatic. This is the case of a female white patient aged 16, with health backgrounds referred to Maxillofacial consultation due to an of right hemifacial increase without another accompanying symptomatology. At physical examination there is an increase in volume of right maxillary region. In computerized axial tomography (CAT) a hyperdense lesion occupying all right maxillary sinus with areas of higher density without affecting the orbit floor bone. Under nasotracheal general anesthesia a hemimaxillotomy was carried out, tumor removal and obturator immediate prosthesis placing. At a year of clinical course and radiography definitive prosthesis was placed without tumor relapse(AU)

Título: Stroke of a cardiac myxoma origin / Acidente vascular cerebral com origem em mixoma cardíaco
Fonte: Rev. bras. cir. cardiovasc = Braz. j. cardiovasc. surg. (impr.);30(2):225-234, Mar-Apr/2015. tab.
Idioma: en.
Resumo: 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 ...

Título: Biatrial approach provides better outcomes in the surgical treatment of cardiac myxomas
Fonte: Rev. bras. cir. cardiovasc = Braz. j. cardiovasc. surg. (impr.);31(4):309-317, July-Sept. 2016. tab, graf.
Idioma: en.
Resumo: Abstract Objective: We aimed to present clinical features, surgical approaches, importance of surgical technique and long-term outcomes of our patients with cardiac myxoma who underwent surgery. Methods: We retrospectively collected data of patients with cardiac myxoma who underwent surgical resection between February 1990 and November 2014. Biatrial approach is the preferred surgical method in a large proportion of patients that are operated due to left atrial myxoma because it provides wider exposure than the uniatrial approach. To prevent recurrence during surgical resection, a large excision is made so as to include at least 5 mm of normal area from clean tissue around the tumor. Moreover, special attention is paid to the excision that is made as a whole, without digesting the fragment of tumor with gentle dissections. Results: Forty-three patients (20 males, mean age of 51.7±8.8 years) were included. Most common symptom was dyspnea (48.8%). Tumor was located in the left atrium in 37 (86%) patients. Resections were achieved via biatrial approach in 34 patients, uniatrial approach in 8 patients, and right atriotomy with right ventriculotomy in 1 patient. One patient died due to low cardiac output syndrome in the early postoperative period. Mean follow-up time was 102.3±66.5 months. Actuarial survival rates were 95%, 92% and 78% at five, 10 and 15 years, respectively. Recurrence was observed in none of the patients during follow-up. Conclusion: Although myxomas are benign tumors, due to embolic complications and obstructive signs, they should be treated surgically as soon as possible after diagnosis. To prevent recurrence, especially in cardiac myxomas which are located in left atrium, preferred biatrial approach is suggested for wide resection of the tumor and to avoid residual tumor.

Título: Resection of left atrial myxoma in a patient with retrosternal gastric tube: a case report
Fonte: Rev. bras. cir. cardiovasc = Braz. j. cardiovasc. surg. (impr.);32(5):438-441, Sept.-Oct. 2017. tab, graf.
Idioma: en.
Resumo: Abstract The median sternotomy remains the standard approach in cardiovascular surgery but, in some conditions, it can be considered difficult to perform, especially in patients with history of esophagectomy. This case report describes a successful resection of a left atrial myxoma through a right anterolateral thoracotomy approach in a patient with a previous retrosternal gastric tube reconstruction. The decision for the best surgical approach was made after a heart surgery team discussion. Through this surgical access, a safe and excellent exposure of the left atrium was possible, and a complete resection of the myxoma was performed without any injury to the gastric tube.

Título: Enfermedad cardioembólica cerebral a partir de un tumor primario de cavidades cardíacas izquierdas / Cerebral cardioembolic disease from a primary tumor of the left heart chambers
Fonte: Rev. cuba. med. mil;49(4):e352graf.
Idioma: es.
Resumo: Introducción: De los tumores cardiacos primarios, el 75 por ciento son benignos y más de la mitad corresponde a mixomas. Pueden ser asintomáticos o generar manifestaciones cardíacas, sistémicas o embólicas, estas últimas frecuentes. Objetivo: Divulgar la importancia de tener presente el tumor primario cardiaco como causa de enfermedad embólica cerebral. Caso clínico: Hombre de 53 años de edad, con mareos, cefalea, malestar general, decaimiento, dolores articulares, palpitaciones, disnea y ortopnea. Sufrió pérdida de la conciencia y posteriormente pérdida de la fuerza muscular del hemicuerpo izquierdo debido a un accidente vascular encefálico de tipo embólico. Con el ecocardiograma transtorácico, se confirmó el diagnóstico de un tumor primario cardiaco. Después de la operación, se comprobó en anatomía patológica, que era un mixoma. Conclusiones: El mixoma es un tumor que puede producir fenómenos cardioembólicos y se debe tener presente en pacientes como el que se presenta(AU)

Introduction: Of the primary cardiac tumors, 75 percent are benign and more than half correspond to myxomas. They can be asymptomatic or generate cardiac, systemic or embolic manifestations, the latter frequent. Objective: To remark the importance of considering the primary cardiac tumor as a cause of cerebral embolic disease. Clinical case: 53-year-old man with dizziness, headache, general malaise, weakness, joint pain, palpitations, dyspnea and orthopnea. He suffered loss of consciousness and later loss of muscle strength in the left half of the body due to an embolic-type stroke. With the transthoracic echocardiogram, the diagnosis of a primary cardiac tumor was confirmed. After the operation, it was verified in pathological anatomy, that it was a myxoma. Conclusions: Myxoma is a tumor that can produce cardioembolic phenomena and must be taken into account in patients like the one presented(AU)

Título: Mixoma Mandibular. Revisión Bibliográfica. A propósito de 2 casos clínicos / Mandibular myxoma: two clinical cases and a literature review
Fonte: Odontoestomatol;17(26):65-77, nov. 2015.
Idioma: en; es.
Resumo: El mixoma mandibular odontogénico, es un tumor de origen mesénquima y representa del 0.5 al 17.7 % de los tumores odontogénicos. Se ubica en el tercer lugar de acuerdo a la frecuencia de presentación. Es un tumor benigno, localmente agresivo y con tendencia a la recidiva, lo que condiciona su tratamiento. En el presente trabajo se describen dos casos clínicos con diagnóstico de mixoma mandibular: un paciente de 33 años y otro de 60. Los dos casos fueron tratados mediante la técnica de mandibulectomía segmentaria sin desarticulación, con margen de seguridad, según el protocolo del Prof. Dr. A. Pogrel, con placa de reconstrucción mandibular, por abordaje extra e intraoral y sin interposición de injerto en el primer tiempo quirúrgico. Se discuten las características del tumor mixoma mandibular y sus opciones terapéuticas en los dos casos clínicos.

The mandibular odontogenic myxoma is a tumor of mesenchyme origin. It represents a 0.5 to 17.7 % of the odontogenic tumors. It is in third place according to the presentation frequency. This tumor is a histologically benign one but locally aggressive and with tendency to recurrence, which determine the treatment. In the present work two cases diagnosed with mandibular myxoma are reported: one is a 33 years old and the second is 60 years old. The both patients were surgically treated with the segmental mandibulectomy technique without disarticulation, with safety margins according to Prof. Dr. A Pogrel protocol, with an immediate reconstruction appliance, extra and intra approach and without graft interposition in the first surgical time. The tumor characteristics of the two patients with mandibular myxoma are discussed and their therapeutic options.
