Comparison of quantitative flow ratio with instantaneous wave‐free ratio and resting full‐cycle ratio during daily routine in the catheterization laboratory
Abstract:Background
Quantitative flow ratio (QFR) is a novel, software‐based method to evaluate the physiology of coronary lesions. The aim of this study was to compare QFR with the established invasive measurements of coronary blood flow using instantaneous wave‐free ratio (iFR) or resting full‐cycle ratio (RFR) in daily cathlab routine.
Methods
102 patients with stable coronary artery disease and a coronary stenosis of 40%−90% were simultaneously assessed with QFR and iFR or RFR. QFR‐computation was performed by two … Show more
