Homem de 41 anos em insuficiência cardíaca sistólica, CF III NYHA, estágio clínico C, por cardiomiopatia dilatada, foi submetido ao transplante autólogo da fração mononuclear da medula óssea, via sistema arterial coronariano, através de cateterismo cardíaco. Dois meses após o procedimento, houve diminuição do BNP plasmático, diminuição da área cardíaca ao estudo radiológico do tórax e à ressonância nuclear magnética. O ecocardiograma demonstrou diminuição do fluxo regurgitante secundário a dilatação do anel mitral. Na ergoespirometria houve melhor desempenho, com aumento do consumo máximo de oxigênio, sendo possível redução da terapêutica medicamentosa. A ausência de eventos adversos caracterizados por: instabilidade clínica/hemodinâmica, alteração enzimática ou eletrocardiográfica apontam para segurança e exeqüibilidade deste procedimento realizado e descrito com pioneirismo na cardiomiopatia dilatada.

A forty-one-year-old male with systolic heart failure, FC-III NYHA, clinical stage C due to dilated cardiomyopathy was submitted to an autologous transplant of the mononuclear fraction of bone marrow via coronary artery system through heart catheterism. Two months after the procedure, there was a decrease in plasma BNP and cardiac area reduction at the thorax X-ray and nuclear magnetic resonance. The echocardiogram showed decrease of the secondary regurgitation and mitral ring dilatation. There was a better performance at the ergospirometry, with increase of the maximum oxygen consumption and consequent reduction in drug therapy. The absence of adverse events characterized by clinical/hemodynamic instability, enzymatic alteration or electrocardiogram demonstrate the safety and feasibility of this procedure carried out and described with pioneering spirit in dilated cardiomyopathy.

Only rarely do myxomas originate from the mitral valve. This is the report of a 49-year-old woman presenting with congestive heart failure. The diagnosis of an intracardiac tumor involving the anterior cuspid of the mitral valve was made by transesophageal echocardiography. The patient underwent surgery for tumor resection and plasty of the valve was made with reconstruction and preservation of the valve. The diagnosis of myxoma was confirmed by histology. This is the 23rd case of myxoma of the mitral valve reported in the literature.
