Abstract:
Cette étude à pour but de développer un concept de stent atraumatique pour le remplacement percutanée de la valve aortique. Le stent est obtenu à partir de brins de Nitinol tressés, ce qui lui permet, de part sa géométrie et sa structure, d'être compressible, auto-expansible, et atraumatique. Le principe de fabrication des prototypes et les contraintes qui lui est associé sont présentées. Les performances de ces prototypes, en terme d'ancrage, de régurgitation statique et de régurgitation dynamique sont ensuite évaluées par des essais in vitro, pour lesquel le banc de test en flux pulsé a été

O expressivo número de brasileiros que necessitam correção anatômica da estenose valvar aórtica acentuada e que não realizam cirurgia de substituição valvar devido ao risco proibitivo justifica a necessidade de investigação, tanto da efetividade no cenário clínico real quanto dos custos impostos ao Sistema Único de Saúde e aos planos de saúde suplementar brasileiros pela incorporação do implante transcateter de valva aórtica, que tem se demonstrado efetivo mas oneroso, internacionalmente.

Introdução: Uma nova alternativa de tratamento foi desenvolvida, o Implante por Cateter de Bioprótese Valvar Aórtica (TAVI, em inglês, Transcatheter Aortic Valve Implantation), indicado para os pacientes portadores de estenose aórtica grave com várias comorbidades, considerados inoperáveis pelo tratamento cirúrgico convencional. O TAVI ainda não foi incorporado ao rol de políticas de saúde do Brasil pelo Sistema Único de Saúde (SUS), tampouco pela Agência Nacional de Saúde Suplementar (ANS), pois há escassez de evidências científicas fundamentadas em análise econômica do procedimento que relat

Abstract:
INTRODUCTION: TAVI has settled as the standard of care of AS for inoperable, high-risk, and selected intermediate-risk patients undergoing aortic valve replacement. Vascular and bleeding complications are related to worst outcomes. HYPOTHESES: a. The reduction and early recognition of vascular and bleeding complications might improve clinical outcomes in patients treated with TAVI. b. A full percutaneous transfemoral approach for TAVI is related to a lower rate of major bleedings in comparison to the surgical cut-down approach. c. The development of post-TAVI thrombocytopenia has a pr

Abstract:
Background The most likely mechanisms of neurological injury following transcatheter aortic valve implantation (TA VI) and aortic valve replacement (A VR) are cerebral embolisation and hypoperfusion. Primary aim was to compare the potential mechanisms of neurological injury following TA VI and A YR. Methods 127 consecutive high risk patients with severe aortic stenosis who underwent TA VI (n=85) or A VR (n=42) were studied. Transcranial Doppler (TCD), cerebral oximetry, diffusion-weighted MRI (DW -MRI) (before, 6 days and 3 months following procedure) and neurocognitive assessment before and a

Abstract:
Aortic stenosis is a life-threatening valvular heart disease. At the onset of symptoms, a patient’s prognosis becomes poor and the risk of death rapidly increases. Aortic valve replacement surgery remains the gold standard in treatment for aortic stenosis. However, in the total population of patients with severe aortic stenosis, about one third are deemed inoperable due to their high surgical risk. In recent years, the development of transcatheter aortic valve implantation (TAVI), a non-invasive heart valve replacement procedure brought hope for the elderly, high-risk and inoperable aortic st
