Summary
Justin Davies introduces the concepts of iFR (Instantaneous wave-Free Ratio) and discusses the underlying physiological principals and usese case examples to demonstrate how it is being used in contemporary clinical practice.
- Understand the background of iFR
- Phasic relationship of pressure and flow
- How pressure gradient varies accross the cardiac cycle
- Why we can measure iFR at rest
- Why we need to measure FFR during hyperaemia
- How to make a measurement of iFR

Dr Justin Davies is a honorary interventional cardiologist at Hammersmith Hospital, Imperial College NHS Trust, London. After training at Imperial College, he won a prestigious BHF research fellowship to study arterial haemodynamics. Since then he has continued to work on the development of mathematical algorithms to aid understanding of large artery physiology and to develop new tools to assess arterial disease. The holder of several patents, he has published widely in the field of hypertension, coronary and large artery physiology and is the winner of many national and international awards. He has several international collaborations, and is the developer of iFR and the co-principal investigator of the ADVISE studies, the DEFINE-FLAIR, ORBITA and DEFINE-PCI studies. Justin also has an interest in renal denervation, and has lead the first-in-man studies to evaluate the safety of this technique to patients with chronic systolic heart failure (REACH studies).
