RESUMO
A 61-year-old female patient using a mechanical prosthesis for 11 years was admitted to the hospital with sudden dyspnea, pallor and atrial fibrillation. The diagnostic evaluation included transesophageal echocardiogram, which showed a significantly reduced motion of one of the leaflets of the mitral prosthesis and immobility of the other, in addition to a thickened structure compatible with a thrombus adherent to the valve. The patient was diagnosed with thrombosis of mechanical mitral valve prosthesis. Thrombolytic therapy (rtPA) was started successfully. The patient has been followed up for more than one year with a favorable outcome.

Mulher com 61 anos de idade, portadora há 11 anos de prótese mecânica, foi internada com dispnéia súbita, palidez e fibrilação atrial. A avaliação diagnóstica incluiu ecocardiografia transesofágica, que demonstrou restrição importante da mobilidade de um dos folhetos da prótese mitral e imobilidade do outro, juntamente com imagem de espessamento compatível com trombo aderido à valva. Foi feito o diagnóstico de trombose de prótese mecânica mitral e instituída terapia trombolítica (rtPA) com sucesso. A paciente está em acompanhamento há mais de um ano, com evolução satisfatória.
