    • The NEVO™ stent provides:
    • CoCr stent platform
    • - Flexible, conformable, thin struts, maximized vessel coverage, open cell design
    • Reservoir Technology (RES-TECHNOLOGY™)
      • - Reduced contact between vessel wall and polymer
    • Biodegradable polymer
    • - Rapid endothelialization
      • - Inflammation scores on par with BMS
      • - Tailored sirolimus release achieving CYPHER ® -like tissue levels
    • Sirolimus
        • - Largest body of clinical evidence

  • Intervencionismo Cardiaco 2008-09 CONCLUSIONES
    • La cirugía presenta mejores resultados que la ICP en pacientes con enfermedad de 3 v y/o TCI a los 2 años de seguimiento a expensas de una mayor necesidad de nueva revascularización con ICP.
    • Los pacientes con Syntax score bajo evolucionan de forma parecida entre ICP y cirugía coronaria.
    • Los pacientes con enfermedad de tronco pueden beneficiarse de la ICP. Se requieren estudios multicéntricos diseñados a este objetivo.
    • Los stent farmacoactivos de 2ª generación son más eficaces y más seguros que los de 1ª generación (Taxus ™ )
