ResumoObjetivo: Comparar os resultados da retirada de introdutor arterial pelo enfermeiro especializado em Unidade de Hemodinâmica e pelo médico residente em Cardiologia Intervencionista em pacientes submetidos à intervenção coronária percutânea.Métodos: Trata-se de registro prospectivo em 100 pacientes submetidos à intervenção coronária percutânea, no período de setembro a outubro de 2004, divididos em dois grupos: Grupo A (GA) -enfermeiro (n = 48 pacientes) -e Grupo B (GB) -médico residente (n = 52 pacientes). Hematoma pequeno foi definido como inchaço palpável no local da punção menor que 2 cm; hematoma moderado, com 2 a 6 cm de diâmetro; e hematoma grande, maior que 6 cm de diâmetro. A dose de heparina foi de 100 UI/kg. Os introdutores foram retirados após controle do tempo de coagulação ativado (TCA < 180 segundos), e foi realizada compressão manual por 15 minutos.Resultados: A idade dos pacientes foi de 59,54 ± 11,1 anos (GA) e 61,7 ± 10,4 anos (GB), com predomínio do sexo masculino (GA = 75% e GB = 58%). Os introdutores foram 7 French. O tempo de compressão manual foi de 19,4 ± 3,1 minutos no GA e 19,6 ± 3,1 minutos no GB (P = 0,76). Ocorreram oito hematomas no GA (sete pequenos e um moderado) e nove hematomas no GB (sete pequenos e dois moderados), P = não-significante. Os hematomas foram tratados clinicamente, sem complicações.Conclusão: A retirada de introdutor arterial, após intervenções coronárias percutâneas, pode ser realizada pelo enfermeiro especializado em Unidade de Hemodinâmica ou pelo médico residente em Cardiologia Intervencionista com segurança e sem complicações maiores.

AbstractObjective: To compare the results of sheath removal by the catheterization lab specialist nurse and by the interventional cardiology resident in patients submitted to a percutaneous coronary intervention.
Background:The Brazilian Public Health System (SUS) establishes that coronary angioplasties with implantation of two stents must not exceed 20% of the total amount of angioplasties performed, resulting in the necessity of staged procedures in the majority of the patients with multivessel coronary disease. The objective of this study was to compare the costs of the staged stent implantation policy, imposed by SUS, with the stent implantation approach considered ideal by the interventional cardiology team, in patients with multivessel coronary disease. Methods: Costs were compared in a consecutive cohort of 100 patients with multivessel disease with indication of complete revascularization by percutaneous coronary intervention. Coronary angiographies had been previously evaluated by the interventional cardiology team that had individualized the approach considered ideal for the treatment of each patient. Procedures were then performed in accordance to SUS multistage policy and the costs of the two treatment strategies were compared. Of note, a single stent implantation procedure costs R$4,298.00 according to the SUS price list. Results: Mean age was 61.5±10.7 years, 66% were male, 43% diabetics and 67% had stable angina. Agreement in relation to the SUS staged procedures occurred in 44% and discordance in 56%. An excess of 58 procedures was detected, generating an additional cost of R$131,298.00. Conclusions: The multistaged approach imposed by SUS increases the number of procedures for coronary stent
SummaryObjective: To compare restenosis and major cardiac event rates at one and six months after DLC-coated stent implantation with those of uncoated stents.

ResumoFundamento: O Sistema Único de Saúde (SUS) estabelece que a angioplastia coronariana com o implante de duplo stent não deve exceder 20% das angioplastias, resultando na necessidade de escalonar a maioria dos procedimentos nos pacientes com doença multiarterial.Objetivo: O objetivo do presente estudo foi avaliar os valores remunerados pelo SUS para a obtenção da revascularização miocárdica percutânea completa em pacientes do SUS com doença multiarterial relacionados ao número de procedimentos necessários e de stents implantados.

BACKGROUND:In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. Therefore, new information on bare metal stents is of great importance. The primary endpoint was to evaluate the influence of the alloy and the profile of coronary stents on late loss and restenosis rates 6 months after implantation in patients with multivessel coronary disease.METHODS:Single center, randomized and prospective study comparison of cobalt–chromium versus stainless steel stent implantation in 187 patients with multivessel coronary disease. At least one cobalt–chromium and one stainless steel stent were implanted per patient.RESULTS:Mean age of patients was 59.5±10.1 years with a prevalence of males (66.3%) and patients with acute coronary syndrome (56%). Baseline clinical characteristics were similar with hypertension in 146 (78%), dyslipidemia in 85 (45.5%) and diabetes in 68 (36.4%). Two hundred and twenty-nine cobalt–chromium and 284 stainless steel stents were implanted. Angiographic variables showed no statistically significant difference. Angiographic follow-up to 6 months after implantation showed similar late loss and restenosis rates.CONCLUSION:The use of two different alloys, stainless steel and cobalt–chrome stents, in the same patient and in the same vessel produced similar 6-month restenosis and late loss rates.
A male 39 year-old patient with post-infarction angina. The coronary angiography showed total proximal obstruction of right coronary artery (RCA), obstructive lesions of 95% of the anterior descending artery (ADA), 80% of the second left marginal branch (LM2), and 95% of the circumflex artery (CXA). The patient was successfully implanted with a Taxus 3.0 x 24 mm stent and an Express 2.75 x 24 mm stent in the proximal and distal thirds of the RCA, respectively, and with an Infinnium 3.0 x 24 mm stent in the ADA. After seven months, the patient had an anterior acute myocardial infarct (AMI) due to thrombosis of the Infinnium stent and restenosis of the Taxus stent, with no loss of results in the conventional stents.
