Fractional flow reserve and instantaneous wave-free ratio in coronary artery bypass grafting: a meta-analysis and practice review [PDF]

Frontiers in Cardiovascular Medicine
ObjectiveFractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are invasive methods to assess the functional significance of intermediate severity coronary lesions.

Análise comparativa do fractional flow reserve (FFR) e do instantaneous wave‐free ratio (iFR): resultados de um registo de 5 anos

Revista Portuguesa de Cardiologia, 2018
Resumo: Introdução e objetivos: A avaliação de lesões coronárias pelo instantaneous wave free ratio (iFR) tem gerado debate. Pretendeu‐se analisar o desempenho diagnóstico do iFR e o seu impacto na decisão de usar o fractional flow reserve (FFR) e nas ...

Hemodynamic and Lesion Characteristics Associated with Discordance between the Instantaneous Wave-Free Ratio and Fractional Flow Reserve [PDF]

Journal of Interventional Cardiology, 2019
Background. The instantaneous wave-free ratio (iFR) is an invasive coronary physiological index that is not inferior to fractional flow reserve- (FFR-) guided revascularization. The indexes of iFR and FFR are similar and closely correlated, but there are

Adverse Plaque Characteristics Relate More Strongly With Hyperemic Fractional Flow Reserve and Instantaneous Wave-Free Ratio Than With Resting Instantaneous Wave-Free Ratio [PDF]

JACC: Cardiovascular Imaging, 2020
The current substudy of the PACIFIC (Prospective Comparison of Cardiac PET/CT, SPECT/CT Perfusion Imaging and CT Coronary Angiography With Invasive Coronary Angiography) trial explores the impact of computed tomography (CT)-derived unfavorable plaque features on both hyperemic and non-hyperemic flow indices.Next to lesion severity, plaque vulnerability
