At the American College of Cardiology’s (ACC) annual meeting, March 16-18 in New Orleans, Philips announced the results of the DEFINE PCI [1] study, which assessed the level of residual ischemia found in patients after percutaneous coronary interventions (PCI). This study found that 1 in 4 patients [1] treated with standard-of-care PCI left the cath lab with residual ischemia (iFR < 0.90), as demonstrated by using a blinded instantaneous wave-free ratio (iFR) pullback measurement, which is Philips’ new physiologic guidance technology.
