The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a [[Stenosis|Stenosis]] is causing a limitation of blood flow in [[Coronary arteries|Coronary arteries]] with subsequent [[Ischemia|Ischemia]].

iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary arteries that are to be assessed. Pressure wires are commonly used by interventional cardiologists to guide decisions to perform revascularization, either by stenting or bypass surgery.
