ABSTRACT

OBJECTIVES: To describe the incidence of thromboembolic events in adult patients with severe COVID-19 and identify clinical and laboratory factors associated with these events. DESIGN: Observational retrospective cohort study of 243 adult patients with severe COVID-19 admitted to an intensive care unit (ICU) at a Brazilian tertiary hospital. RESULTS: The incidence of all thromboembolic events was 14.8%, in which 3.8% developed deep vein thrombosis, 7.8% pulmonary embolism, 2.5% acute myocardial infarction, 1.2% stroke, and 1.2% peripheral artery occlusion. Risk factors identified were D-dimer at admission >3000 ng/mL (P=<0.0013) and major bleeding (P=0.001). The cumulative risk of developing thromboembolic events at day 28 after ICU admission was 16.0%. The rate of major bleeding was 4.1%. After receiver operating characteristic curve analysis, the D-dimer cut-off at admission correlating with thromboembolic events was 1140.5 ng/mL. CONCLUSIONS: The rate of thromboembolic events in our study was lower than previously described. High D-dimer level at admission was the leading risk factor; the optimal cut-off was 1140.5 ng/mL. The occurrence of thromboembolic events did not have an impact on the median overall survival rate. The optimal anticoagulant strategy in this context still needs to be established.

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

OBJECTIVE: To present a technical proposal based on the experience of 130 implantations using a simplified technique for coronary sinus catheterization, based on the atrial component of the intracavitary electrogram and radiological anatomy. METHODS: From October, 2001 to October, 2004, 130 biventricular pacemaker implantations were performed, using radiological anatomy and observation of the intracavitary electrogram, focusing on the atrial component. RESULTS: The implantation of the system using left ventricular pacing via coronary sinus was not possible in 8 patients. Difficulties on the cannulation of the coronary ostium were felt in 12 patients and difficulties of lead advancement through the coronary sinus were felt in 15 patients. The mean time of radioscopy utilization was 18.69 min. CONCLUSION: The implantation technique, using the atrial component morphology of the intracavitary electrogram and radiological anatomy showed to be workless, safe and effective for the cannulation of the coronary sinus ostium requesting reduced time of radioscopy.

ABSTRACT

OBJETIVO: Apresentar uma proposição técnica baseada na experiência de 130 implantes utilizando técnica simplificada para cateterização do seio coronariano, baseada no componente atrial do eletrograma intracavi-tário e anatomia radiológica. MÉTODOS: De outubro de 2001 a outubro de 2004 foram realiza-dos 130 implantes de marcapasso biventricular, utilizando-se anatomia radiológica e observação de eletrograma intracavitário, com prioridade ao componente atrial. RESULTADOS: O implante do sistema, utilizando-se a estimulação do ventrículo esquerdo via seio coronariano, não foi possível em 8 pacientes. Em 12 pacientes foram observadas dificuldades na canulação do óstio coronário e em 15 pacientes observaram-se dificuldades de progressão do eletrodo através do seio coronariano. O tempo médio de utilização de radioscopia foi de 18,69 min. CONCLUSÃO: A técnica de implante, utilizando a morfologia do componente atrial do eletrograma intracavitário e anatomia radiológica, demonstrou ser pouco trabalhosa, segura e eficaz para canulação do óstio do seio coronariano, necessitando de reduzido tempo de radioscopia.

ABSTRACT

OBJETIVO: Apresentar a experiência de 157 implantes utilizando uma técnica simplificada para cateterizacão do seio coronariano, baseada no eletrograma intracavitário e anatomia radiológica, demonstrando o porcentual de sucesso e tempo total de utilizacão de radioscopia. MÉTODO: De outubro de 2001 a fevereiro de 2005, foram realizados 157 implantes de marcapasso biventricular em pacientes previamente selecionados, utilizando-se anatomia radiológica e observacão de eletrograma intracavitário, demonstrando a taxa de sucesso, complicacões e tempo total de utilizacão de radioscopia. RESULTADOS: O implante do sistema, utilizando-se a estimulacão do ventrículo esquerdo via seio coronariano, não foi possível em onze procedimentos. Em 20 pacientes foram observadas dificuldades na canulacão do óstio coronário e em 39 pacientes observou-se dificuldade de progressão do eletrodo através do seio coronário. O tempo médio de utilizacão de radioscopia foi 18,27 n 15,46 min. CONCLUSAO: A técnica de implante, proposta pelo autor, utilizando o eletrograma intracavitário e anatomia radiológica, demonstrou ser segura e eficaz para canulacão do óstio do seio coronário, necessitando de reduzidos tempos de radioscopia.
