iFR diagnostic accuracy using FFR as gold standard : insights from a 5-year experiencePublished on behalf of the European Society of Cardiology. All rights reserved. © The Author 2017. For permissions, please email: journals.permissions@oup.com.Background: Functional coronary lesion assessment by fractional flow reserve (FFR) is commonly employed worldwide. Recently, several studies have focused on a new parameter, the instantaneous wave free ratio (iFR), as an alternative or complementary method to FFR which does not require the use of adenosine. The use of iFR, however, is not consensual: its ideal cut-off and interpretation are still not completely established. Purpose: We aimed to analyse the diagnostic accuracy of iFR using FFR as gold standard. Methods: Retrospective analysis of all patients undergoing functional coronary lesion assessment during 5 years. FFR was used as a gold standard for assessing the diagnostic accuracy of iFR in every patient who underwent measurements with both techniques. The decision was made on an individual patient basis according to the operator's decision. For statistical analysis we used Receiver Operating Characteristics (ROC) curve. The test was undertaken for 2 FFR cut-offs: ≤0,80 and <0,75. Results: Functional testing was undertaken in 326 patients (67±11 years, 65,6% male), encompassing 402 lesions. 154 lesions underwent assessment with both techniques, 222 by FFR only and 26 cases iFR only.Oxford University PressRepositório da Universidade de LisboaFrancisco, Ana RitaMenezes, MiguelLima da Silva, G.Gonçalves, InêsRigueira, JoanaCarrilho-Ferreira, PedroJorge, C.Infante de Oliveira, EduardoTorres, D.Cardoso, P.Pinto, Fausto J.Canas da Silva, Pedro2019-11-04T16:43:35Z20172017-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10451/40047engEuropean Heart Journal, Vol. 38, Issue suppl_1, Aug 2017, ehx502.P23710195-668X10.1093/eurheartj/ehx502.P2371info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:39:08Zoai:repositorio.ul.pt:10451/40047Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:53:47.564162Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
