    <p>Female patient, 45 years-old, reported dyspnea on routine efforts with 6 months of evolution with dry cough. Previously healthy she refused to take regular medication. According to the physical examination, she had a heart rate of 105 bpm, blood pressure of 90x60mmHg, respiratory frequency 30 incursions per minute, arterial saturation of 88%, slow capillary filling time, rhythmic sounds, diastolic rumble murmur (+++/6) in mitral focus and bibasal pulmonary crepitations. Chest X-Ray showed a discreet widening of the mediastinum. Chest CT was performed to evaluate the mediastinum and pulmonary parenchyma and an intracardiac mass was found. It evolved with hypotension and worsening of pulmonary congestion.</p>
    <p>Emergency echocardiogram showed a moving rounded hyperechoic image in the left atrium, measuring 66x36mm with a pedicle adhered to the membrane of the oval fossa dislocating to the left ventricle (LV) during systole causing hemodynamic repercussion (signs of LV outflow tract obstruction). The patient underwent emergency surgery. Retraction of the tumor revealed a cleft in the anterior cusp of the mitral valve and it was closed. In the immediate postoperative, the patient developed cardiogenic shock refractory to vasoactive drugs; an intra-aortic balloon was implanted, but the patient died 30 hours later. Anatomopathological confirmed the diagnosis of a myxoma: 7.5x4.6x3.4cm. In conclusion, the atrial myxoma with obstruction of the outflow tract of the LV is rare, its clinical manifestations can mislead the evaluator, clinical suspicion and the correct use of propaedeutic are essential for early diagnosis and successful clinical treatment.</p>

      <p>Paciente de 47 anos, feminino, referia dispneia aos esfor&#231;os habituais com 6 meses de evolu&#231;&#227;o acompanhada de tosse seca. Previamente h&#237;gida, negava uso de medica&#231;&#245;es regulares. Ao exame f&#237;sico, encontrava-se com frequ&#234;ncia card&#237;aca de 105 bpm, press&#227;o arterial de 90x60mmHg, frequ&#234;ncia respirat&#243;ria de 30 incurs&#245;es por minuto, satura&#231;&#227;o arterial 88%, tempo de enchimento capilar lentificado, bulhas r&#237;tmicas, sopro diast&#243;lico em ruflar (+++/6) em foco mitral e crepita&#231;&#245;es pulmonares bibasais. Raio X de t&#243;rax evidenciou um alargamento discreto do mediastino. Realizou-se tomografia de t&#243;rax para avalia&#231;&#227;o de mediastino e par&#234;nquima pulmonar e descobriu-se uma massa intracard&#237;aca. Evoluiu com hipotens&#227;o e piora da congest&#227;o pulmonar. Realizado ecocardiograma de urg&#234;ncia mostrou imagem hiperecog&#234;nica no interior do &#225;trio esquerdo, arredondado, m&#243;vel, de 66x36 mm com ped&#237;culo aderido &#224; membrana da fossa oval deslocando&#8209;se para o interior do ventr&#237;culo esquerdo (VE) durante a s&#237;stole, causando repercuss&#227;o hemodin&#226;mica (sinais de obstru&#231;&#227;o da via de sa&#237;da do VE). A paciente realizou tratamento cir&#250;rgico de urg&#234;ncia. Ap&#243;s ex&#233;rese do tumor foi evidenciado cleft na c&#250;spide anterior da valva mitral e realizado seu fechamento. No p&#243;s operat&#243;rio imediato, a paciente evoluiu com choque cardiog&#234;nico refrat&#225;rio a drogas vasoativas, foi implantado bal&#227;o intra a&#243;rtico, mas a paciente evoluiu para &#243;bito ap&#243;s 30 horas. Anatomopatol&#243;gico confirmou o diagn&#243;stico de mixoma 7,5x4,6x3,4cm. Em conclus&#227;o, o mixoma atrial com obstru&#231;&#227;o de via de sa&#237;da de VE &#233; raro, as manifesta&#231;&#245;es cl&#237;nicas podem confundir o avaliador, a suspei&#231;&#227;o cl&#237;nica e uso correto da proped&#234;utica &#233; essencial para um diagn&#243;stico precoce e tratamento cl&#237;nico de sucesso.</p>
