Improvement in coronary haemodynamics after percutaneous coronary intervention: assessment using instantaneous wave-free ratio.
OBJECTIVE: To determine whether the instantaneous wave-free ratio (iFR) can detect improvement in stenosis significance after percutaneous coronary intervention (PCI) and compare this with fractional flow reserve (FFR) and whole cycle Pd/Pa. DESIGN: A prospective observational study was undertaken...
