RESUMO
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.

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 mode 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.

PURPOSE--To study the short and long-term follow-up of patients with left main coronary artery disease (LMCAD) and age over 65 years, by comparing the results with patients under 65 years-old. METHODS--Twenty-two patients with LMCAD and mean age of 69 +/- 3.5 years (group I) were underwent isolated coronary artery bypass grafting (CABG) and compared to 31 patients with LMCAD, mean age of 54 +/- 7 years (group II), who also underwent isolated CABG. The life-table Kaplan-Meyer method was used to estimate the post-operative survival. The chi-square and Student "t" test were used when necessary. RESULTS--Despite higher operative mortality in group I (9.1 x 3.2), the difference was statistically not significant. The operative morbidity was similar in both groups. Actuarial survival at 4 years was 85 in group I and 95 in group II. Actuarial survival free of cardiac events was 69 in group II and 75 in group II. CONCLUSION--The CABG is well tolerated and had low morbidity and acceptable mortality in old patients with LMCAD. The long-term survival in these patients was very similar to the younger patients.
