1. 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

2. Application of the topological optimization technique to the stents cells design for angioplasty
Restoring the internal lumen of arteries by employing an expandable mesh (stent) of metallic or polymeric material, known as angioplasty, is one of the most common procedure for treatment of the obstructive cardiovascular diseases. The stent for angioplasty have been extensively used in the treatment of the cardiovascular diseases. They should be flexible du

3. Análise morfométrica digital na parede aórtica de suínos após implante de stents não revestidos versus stents revestidos com dacron / Digital morphometric analysis on the aortic wall of pigs after implants of non coated stents versus coated stents with dacron
Os stents são dispositivos intravasculares implantados com o objetivo de dilatar ou fixar a placa de colesterol contra a parede arterial. O objetivo avaliar dois tipos de stents de aço inoxidável, um recoberto com poliéster (dacron) e outro não recoberto, implantados na aorta infra-renal de suínos jovens, foram avaliados por morfometria digital para me

4. Análise morfométrica da parede arterial após o implante de stent em aorta abdominal de suínos : estudo comparativo entre stents metálicos não recobertos e recobertos com politetrafluoroetileno / Morphometric analysis of the arterial wall after stent deployment in the pig aorta : comparative study between naked and PTFE covered stainless steel stents
O espessamento intimal e a reestenose que ocorrem após os procedimentos de angioplastia transluminal percutânea e/ou o implante de stents representam uma causa freqüente de falência destes procedimentos. O principal achado patológico responsável pela reestenose parece ser a hiperplasia intimal, já que o dispositivo intravascular é resistente ao remod

5. Desenvolvimento e avaliação de filtro para veia cava inferior stent-filtro.
Implantation of an inferior cava vena filter is recommended for the prevention of pulmonary embolism when anticoagulation fails or is contra-indicated. The aim of this study was to develop and evaluate a new low-cost model of inferior cava vena filter. In reality in this case it is a combination of a inferior cava vena filter with a vascular stent. The mater

6. Right ventricular outflow stent implantation: an alternative to palliative surgical relief of infundibular pulmonary stenosis.
OBJECTIVE: Preliminary assessment of the use of stents for palliative relief of right ventricular infundibular stenosis as an alternative to palliative surgical ventricular outflow enlargement. DESIGN: Descriptive clinical study. PATIENTS: Four patients with right ventricular outflow obstruction, aged between 2 and 15 years. One had had previous palliative s

7. Stenting of the arterial duct combined with banding of the pulmonary arteries and atrial septectomy or septostomy: a new approach to palliation for the hypoplastic left heart syndrome.
OBJECTIVE--To assess the feasibility of pulmonary artery banding, atrial septectomy or septostomy, and percutaneous stenting of the arterial duct in babies with the hypoplastic left heart syndrome. PATIENTS--Four infants with hypoplastic left heart syndrome. SETTING--Two supraregional paediatric cardiac centres. METHODS--Ductal patency was maintained initial
