ABSTRACT

This study describes the impact of the implantation of a document ofresponsibility that should be followed by doctors who do not complywith the guidelines of Hospital de Clínicas when prescribing packedred blood cells. Data analysis shows that the compulsory nature ofthe responsibility terms significantly decreases the number of packedred blood cells transfused in opposition to the Institution guidelines(p < 0.001).

ABSTRACT

CONTEXT AND OBJECTIVES: There are few studies concerning bone marrow mononuclear cell (BMMC) transplantation in cases of nonischemic dilated cardiomyopathy. This study describes a novel technique of BMMC transplantation and the results up to one year after the procedure. DESIGN AND SETTING: This was a case series to evaluate the safety and viability of the procedure, at Instituto de Cardiologia do Rio Grande do Sul. METHODS: Nine patients with symptomatic dilated cardiomyopathy, functional class III/IV and left ventricular ejection fraction (LVEF) < 35 percent received BMMC (9.6 ± 2.6 x 107 cells) at 20 sites in the ventricular wall, by means of thoracotomy of length 5 cm in the fifth left intercostal space. Echocardiograms and nuclear magnetic resonance (NMR) were performed. RESULTS: There were no major complications. The functional class results for the first six patients (preoperatively and at two, four, eight and twelve-month follow-ups, respectively) were: [IV-2, III-4] to [I-5, II-1] to [I-3, II-3] to [I-2, II-3] and [I-2, II-3]. Echocardiograms showed LVEF: 25.9 ± 8.2; 32.9 ± 10.4; 29.4 ± 7.2; 25.1 ± 7.9; 25.4 ± 6.8 percent (p = 0.023); and percent left ventricular (LV) fiber shortening: 12.6 ± 4.4; 16.4 ± 5.4; 14.3 ± 3.7; 12.1 ± 4.0; 12.2 ± 3.4 percent (p = 0.021). LV performance variation seen on NMR was non-significant. CONCLUSION: Intramyocardial transplantation of BMMC in dilated cardiomyopathy cases is feasible and safe. There were early improvements in symptoms and LV performance. Medium-term evaluation revealed regression of LV function, although maintaining improved functional class.


CONTEXTO E OBJETIVO: Há pouco estudos avaliando o transplante de células mononucleares da medula óssea (CMMO) na miocardiopatia dilatada não-isquêmica. O presente estudo descreve uma técnica de implante intramiocárdico de CMMO por mini-toracomia e resultados com até um ano de acompanhamento. TIPO DE ESTUDO E LOCAL: Série casos para avaliar segurança e viabilidade do procedimento, no Instituto de Cardiologia do Rio Grande do Sul. MÉTODOS: Nove pacientes com miocardiopatia dilatada, em classe funcional III/IV e fração de ejeção do ventrículo esquerdo (FEVE) < 35 por cento receberam CMMO (média 9,6 ± 2,6 x 107 células) em 20 pontos da parede livre do ventrículo esquerdo, através de toracotomia de 5 cm no quinto espaço intercostal esquerdo. Foram realizados ecocardiograma e ressonância nuclear magnética (RNM). RESULTADOS: Não ocorreram complicações maiores. Os resultados pré-operatórios aos 2, 4, 8 e 12 meses de acompanhamento dos seis primeiros pacientes são: classe funcional: IV-2, III-4 para I-5, II-1 para I-3, II-3 para I-2, II-3 e I-2, II-3. Ecocardiograma: FEVE = 25.9 ± 8.2, 32.9 ± 10.4, 29.4 ± 7.2, 25.1 ± 7.9, 25.4 ± 6.8 por cento (p = 0.023); Fração de encurtamento do ventrículo esquerdo (VE) = 12.6 ± 4.4, 16.4 ± 5.4, 14.3 ± 3.7, 12.1 ± 4.0, 12.2 ± 3.4 por cento (p = 0.021). RNM demonstrou diferenças discretas, não significativas. CONCLUSÕES: O implante intramiocárdico de células-tronco na miocardiopatia dilatada é viável e seguro. Houve melhora precoce nos sintomas e na performance de VE. Avaliação a médio prazo demonstrou regressão da função VE, mantendo, contudo, a melhora na qualidade de vida e na classe funcional.
