“…O ecodopplercardiograma constitui-se no exame com maior sensibilidade e especificidade para o diagnóstico das massas intracardíacas, principalmente nos mixomas atriais (KAYNAK, et al, 2001;SADEGHI, et al, 2002;FABRICIUS, et al, 2000e GAUDRÉE et al, 2000. Em todos os casos relatados e aqui citados, a ecodopplercardiografia foi o método diagnóstico usado, revelando sua grande acurácia, mesmo sendo um método não-invasivo (ROBERTS, 1997).…”

RESUMOOs tumores cardiovasculares primários são infrequentes, geralmente benignos e com alto potencial embólico. Objetivo: Relatar o caso de um paciente admitido para ressecção de mixoma atrial esquerdo que diante da realização do pré-operatório, evidenciou-se infarto do miocárdio prévio com provável etiologia embólica de fragmento tumoral. O caso a ser descrito corrobora com a literatura descrita sobre o tema pela raridade do mesmo. Metodologia: Relato de caso. Resultados: Ao eletrocardiograma observou-se área eletricamente inativa em parede inferior, o ecodopplercardiograma mostrou mixoma de átrio esquerdo com mobilidade, invadindo a cavidade ventricular na final diástole com a contração atrial esquerda, além de acinesia de parede inferior de ventrículo esquerdo e a cineangiocoronariografia não apresentou lesões coronarianas. Realizado exérese do mixoma atrial esquerdo sem intercorrências e o paciente foi encaminhado para consultas periódicas com ecodopplercardiograma para acompanhamento e tratamento da disfunção ventricular esquerda (sequela do evento isquêmico). Conclusão: Houve fortes indícios de infarto do miocárdio causado por êmbolo tumoral, pois o paciente já havia apresentado outro fenômeno embólico para o encéfalo, somando-se ao fato do exame de cineangiocoronariografia não ter demonstrado lesões coronárias obstrutivas que caracterizassem doença arterial coronariana.Palavras chave: Mixoma atrial; Êmbolo tumoral; Infarto do miocárdio. ABSTRACTPrimary cardiovascular tumors are infrequent, usually benign and with high embolic potential. Objective: To report the case of a patient admitted for resection of left atrial myxoma who, prior to the preoperative period, showed a previous myocardial infarction with probable embolic etiology of a tumor fragment. The case to be described corroborates with the literature described on the subject by its rarity. Methodology: Case report. Results: The electrocardiogram showed an electrically inactive area in the inferior wall, doppler echocardiography showed a left atrial myxoma with mobility, invading the left ventricular cavity in the late diastole with left atrial contraction, as well as left ventricular inferior wall akinesia and the coronary angiography did not present coronary lesions. Performed excision of the left atrial myxoma without intercurrences and the patient was referred for periodic consultations with doppler echocardiography to follow up and treat left ventricular dysfunction (sequelae of the ischemic event). Conclusion: There were strong indications of myocardial infarction caused by tumor plunger, since the patient had already presented another embolic phenomenon to the encephalon, in addition to the fact that the coronary angiography did not demonstrate obstructive coronary lesions that characterized coronary artery disease.

“…They are more commonly found in the left atrium, in contact with the mitral valve, sometimes pedunculated to one of its leaflets (Figure 2). Myxomas of the right atrium, obstructing the outflow tract of the right ventricle, tumoral soft emboli to the lungs and stenosis of the pulmonary valve have also been described [1,[5][6][7].…”

“…Doppler echocardiogram constitutes the examination with the greatest sensitivity and specificity for the diagnosis of intracardiac masses, mainly the atrial myxomas [5,6,9,16]. The presence of pedunculated or sessile vegetating lesions on one of the valvar leaflets or on the valve apparatus, the absence of infectious signs and symptoms and frequently associated with arrhythmia, can lead to the diagnosis of heart tumour.…”

Neoplasms of the cardiovascular system are rare pathologies associated with non-specific signs and symptoms. Cardiac neoplasms should be considered when treating cardiac arrhythmia, Hiss-Purkinje conduction system dysfunction and ischemic syndromes. Tumours of the cardiac muscle are rhabdomyosarcomas that develop frequently in the left chambers, mainly the left ventricle.Among endovascular tumours, the most common one is the myxoma of left atrium and its variant forms. Metastatic tumours of the heart, among them the malignant melanoma, affect the right ventricle more commonly (anterior wall and septum, with invasion of the left ventricle), in the nondisseminated form. Late diagnosis results in high morbidity and mortality rates whether surgical treatment is given or not. The authors describe the case of a right ventricle melanoma patient, comparing the diagnostic approach and treatment with published data. The treatment of choice of cardiac muscle malignant tumours (both primary and metastatic) is non-conclusive according to our literature review. Due to the low incidence of this pathology, the authors suggest additional meta-analytic studies should be performed to establish diagnostic and therapeutic criteria for the malignant tumours of the heart.

“…Histológicamente se caracteriza por estar revestido de endotelio y por la presencia de células poligonales inmersas en una matriz de mucopolisacáridos (Figura 1b) 3 . Aunque es un tumor benigno, algunos pueden recurrir e incluso metastizar 4,5 . Debido a su localización, puede generar obstrucción al flujo de sangre dentro del corazón o embolizar, siendo por lo tanto potencialmente letal 6,7 .…”
