ABSTRACT

BACKGROUND: The cardiac resynchronization therapy (CRT) is an effective option for patients with advanced heart failure (HF). Clinical, electrocardiographic and echocardiographic criteria have been studied in an attempt to find the patients that will benefit from the CRT, considering that the echocardiogram is the method that is used both in the selection and in the assessment of such therapy. OBJECTIVE: The objective of this work is to analyze the use of echocardiogram to assess the CRT, in a ten-day follow-up period and after two years of evolution. METHODS: The assessment considered 20 patients subjected to CRT, for a period of two years, 80% of which were male. The Minnesota Living with Heart Failure Questionnaire (MLWHF) was filled out. Patients underwent a six-minute walking test. Then, the two-dimensional echo-Doppler-cardiogram was performed. The initial assessment was repeated ten days after and two year after the implantation of the biventricular pacemaker. RESULTS: In two years, 5 patients (25%) died; 4 had cardiomyopathy caused by the Chagas's disease. There was no statistically significant change in the ejection fraction between the pre-operation period and the following ten days, but there was a significant change between the pre-operation period and two years after that, and the ten-day period and two years after that. In the ten-day follow-up period, there was the worsening of the intraventricular dyssynchrony, as evaluated by the tissue Doppler method, and the 'living with heart failure' score was higher in the group of deaths. CONCLUSION: Out of the echocardiographic parameters assessed, only the intraventricular dyssynchrony assessment through the tissue Doppler method, after the procedure, was capable of predict the CRT efficiency with respect to the death rate.

ABSTRACT

Fundamento: A terapia de ressincronização cardíaca (TRC) é uma opção efetiva para os pacientes com insuficiência cardíaca (IC) avançada. Critérios clínicos, eletrocardiográficos e ecocardiográficos têm sido estudados na tentativa de selecionar os pacientes que serão beneficiados com a TRC, sendo o ecocardiograma um método utilizado tanto na seleção quanto na avaliação desta terapêutica. Objetivo: O objetivo deste trabalho é analisar a utilização do ecocardiograma na avaliação da TRC, no seguimento de dez dias e após dois anos de evolução. Métodos: Foram avaliados 20 pacientes submetidos à TRC, por um período de dois anos, sendo 80 por cento do sexo masculino. Foi aplicado o Questionário de Qualidade de Vida de Minnesota, o teste de caminhada de seis minutos e realizado o ecodopplercardiograma bidimensional. Dez dias após o implante do marca-passo biventricular, bem como dois anos depois, foi repetida a avaliação inicial. Resultados: Em dois anos, 5 pacientes (25 por cento) foram a óbito; 4 apresentavam cardiomiopatia de etiologia chagásica. Não houve alteração estatisticamente significante da fração de ejeção entre o período pré-operatório e os dez dias seguintes, mas sim uma alteração significante nos períodos de pré-operatório e dois anos e de dez dias e dois anos. No seguimento de dez dias, houve piora da dissincronia intraventricular avaliada pelo Doppler tecidual, assim como a pontuação no escore de qualidade de vida foi maior no grupo óbito. Conclusão: Dos parâmetros ecocardiográficos avaliados, somente a avaliação da dissincronia intraventricular pelo Doppler tecidual após o procedimento foi capaz de predizer a eficácia da TRC em relação à mortalidade.

No hubo alteración estadísticamente significativa de la fracción de eyección entre el período preoperatorio y los diez días siguientes, pero sí una alteración significativa en los períodos de preoperatorio, dos años y diez días y dos años. En el seguimiento de diez días, hubo un empeoramiento de la disincronía intraventricular evaluada por doppler tisular, así como la puntuación en el escore de calidad de vida fue mayor en el grupo óbito.

ABSTRACT

Eustachian valve endocarditis is a rare condition that affects mostly injectable drug users and patients using pacemakers or central venous catheter. We describe the case of a patient who underwent myocardial revascularization with extracorporeal circulation and who presented Eustachian valve endocarditis in the postoperative period, diagnosed by echocardiogram. The blood culture identified Klebsiella pneumoniae. He received appropriate antibiotic therapy and presented resolution of the condition within four weeks.

ABSTRACT

A endocardite em válvula de Eustáquio é uma condição rara, que ocorre geralmente em usuários de drogas injetáveis e em portadores de marcapasso ou cateter venoso central. Apresentamos um caso de paciente que, em pós-operatório de cirurgia de revascularização do miocárdio com circulação extracorpórea, apresentou endocardite em válvula de Eustáquio diagnosticada pela ecocardiografia, sendo identificada Klebsiella pneumoniae à hemocultura. O paciente foi tratado com antibioticoterapia apropriada, apresentando resolução do quadro em quatro semanas.

ABSTRACT

Os autores objetivaram avaliar resultados imediatos e seguimento de um ano da valvoplastia mitral por cateter-balao (VMCB) utilizando o balao Inoue, em 40 pacientes portadores de estenose mitral (EM) sintomaticos e consecutivos, submetidos a VMCB; 37 mulheres, media etaria de 36 (22-67 anos), cinco portadores de ReEM. Trinta e sete estavam em classe funcional III/IV (NYHA) e a VMCBN foi realizada de urgencia em seis pacientes, devido a edema agudo dos pulmoes, incluindo duas gestantes. Foram analisados os dados hemodinamicos no pre e no pos-VMCB imediato e os dados ecodopplercardiograficos (ECO) no pre, pos imediato (POS) e apos 12 meses de seguimento (PO12M). Os resultados hemodinamicos pre X pos foram: gradiente mitral (G)17,6+/-7,6X6,3+/-5,5mmHg; area valvar mitral (AVM) 0,89+/-0,25X1,66+/-0,63cm2; pressao media do atrio esquerdo 25,5+/-9,0X14,3+/-6,4mmHg; pressao media de arteria pulmonar 34,8+/-13,0X23,8+/-10,8mmHg (todos p<0,0001) e indice cardiaco 2,8+/-0,5X2,9+/-0,8l/min/m2 (NS). Tres pacientes apresentaram insuficiencia mitral (IM) moderada, na ventriculografia esquerda pos-VMCB. As complicacoes relacionadas diretamente ao procedimento foram: 2 casos com tamponamento cardiaco necessitando drenagem cirurgica, 3 com comunicacao inter-atrial e 1 com perfuracao de aorta, sem tamponamento cardiaco. Um paciente apresentou acidente vascular cerebral, 72 horas apos a VMCB sem sequela motora. Houve 2 insucessos, sendo que 1 evoluiu para obito 2 meses apos VMCB. Os 29 pacientes que foram efetivamente acompanhados por um periodo de 12 meses nao apresentaram eventos cardiacos; os resultados do ECO PRE X POS X PO12M foram: AVM 1,00+/-0,24X2,12+/-0,33 e G 11,1+/-5,0+/-2,0X5,3+/-2,6. Todos os pacientes estavam em classe funcional I/II apos um ano de seguimento. Portanto, o balao Inoue mostra bons resultados imediatos e no seguimento por um periodo de 12 meses e serve como opcao terapeutica para EM em pacientes sintomaticos selecionados
