The role of resting pressure parameters, i.e. instantaneous wave-free ratio (iFR), and resting distal coronary pressure/aortic pressure (Pd/Pa) in assessing functionally significant stenosis remains controversial. We sought to assess the diagnostic performance of iFR and resting whole-cycle Pd/Pa in Asian patients.
