13. Alterações histopatológicas de stents metálicos no endotélio coronariano \"in vivo\" / Histopathological abnormality in coronary artery bare stent metal \"in vivo\"
Duas técnicas invasivas para o tratamento da doença aterosclerótica coronariana oclusiva firmaram-se ao longo dos anos: revascularização cirúrgica do miocárdio e angioplastia transcutânea com stents metálicos. O estudo visa comparar as alterações histopatológicas causadas por stents metálicos coronarianos fabricados com a superliga de composiç�

14. Achados ultrassonográficos em lesões de bifurcação coronária tratadas com stent único versus estratégia com dois stents / Intravascular ultrasound findings in coronary bifurcation lesions treated with single stenting versus double stenting strategies
Previous comparative studies including selected bifurcation lesions have shown no advantage of elective double stenting implantation versus single stenting. However, the applicability of the provisional technique appears to be dependent on the bifurcation lesion complexity. The lesion luminal area after percutaneous treatment, as assessed by intravascular ul

15. Utilização do ultra-som intracoronário com Histologia Virtual® na identificação de lesões propensas à reestenose após o implante de stents / Application of Virtual Histology®-intravascular ultrasound (VH-IVUS) to identify restenosis-prone lesions after baremetal and sirolimus-eluting stents
To the present, little is known about the correlation between modifications in plaque composition at stent edges and the changes in vessel geometry. This study sought to evaluate, by serial grey-scale intravascular ultrasound (IVUS) and Virtual Histology(TM), the modifications in plaque composition at the edges of drug-eluting and bare-metal stents and the c

16. Avaliação tardia dos stents liberadores de Biolimus A9® pela tomografia de coerência óptica: análise da cobertura tecidual e da aposição das hastes / Long-term follow-up Biolimus A9TM stents with optical coherence tomography: strut apposition and tissue coverage analysis
Introduction: First generation drug-eluting stents (DES) have emerged as a strategy to prevent in-stent restenosis and the need of target-vessel revascularization when compared to bare metal stents (BMS); but at the expense of a higher risk of very late stent thrombosis (ST). Uncovered and malapposed struts may be associated with both late and very late ST.

18. Influence of metal alloy and the profile of coronary stents in patients with multivessel coronary disease
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. The

19. Transperitoneal laparoscopic pyeloplasty: Brazilian initial experience with 55 cases
PURPOSE: To evaluate prospectively the results obtained in 55 patients undergoing laparoscopic pyeloplasty through transperitoneal access. MATERIALS AND METHODS: From January 2005 to July 2009, fifty-five patients between 13 and 64 years old, were treated for ureteropelvic junction (UPJ) stenosis via a transperitoneal laparoscopy. All patients had clinical s

20. Effect of oral sirolimus therapy on inflammatory biomarkers following coronary stenting
We studied the effect of oral sirolimus, administered to prevent and treat in-stent restenosis (ISR), on the variation of serum levels of inflammatory markers following coronary stenting with bare metal stents. The mean age of the patients was 56 ± 13 years, 65% were males and all had clinically manifested ischemia. Serum levels of high sensitivity C-reacti

21. Predictors of restenosis after percutaneous coronary intervention using bare-metal stents: a comparison between patients with and without dysglycemia
The objective of this study was to identify intravascular ultrasound (IVUS), angiographic and metabolic parameters related to restenosis in patients with dysglycemia. Seventy consecutive patients (77 lesions) selected according to inclusion and exclusion criteria were evaluated by the oral glucose tolerance test and the determination of insulinemia after a s

22. Níveis plasmáticos de marcadores imunoinflamatórios na aterosclerose coronariana primária e na reestenose coronariana pós-angioplastia
Objective - To compare circulating plasma levels of immunoinflammatory markers in patients with known de novo coronary artery disease and patients with postangioplasty restenosis. Methods - Using enzymatic immunoabsorbent assay, we measured plasma levels of soluble interleukin-2 receptosr, tumor necrosis factor alpha, and soluble tumor necrosis alpha recepto

23. Postangioplasty restenosis : a practical model in the porcine carotid artery
Transluminal coronary angioplasty is a routine therapeutic intervention in coronary heart disease. Despite the high rate of primary success, restenosis continues to be its major limitation. Porcine models have been considered to be the most adequate experimental models for studying restenosis. One limitation of porcine models is the need for radiological gui

24. Short- and long- term results of percutaneous balloon valvuloplasty in pulmonary valve stenosis
Objective - To assess the long-term results of percutaneous balloon valvuloplasty at a single institution. Methods - This study comprised 189 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty from 1984 to 1996, whose mean age was 7.97±9.25 years. The procedure was classified as successful when the RV-PA gradient was reduce
