DEFINE GPS Global Multicenter Study – First Patient Enrolled: Study to assess Superiority of PCI Procedures Guided by Co-registered iFR and Interventional Angiography

The global, multi-center, prospective, randomized controlled DEFINE GPS study will investigate if guidance by instantaneous wave-free ratio (iFR) measurements co-registered on the angiogram demonstrates superior outcomes and improves the cost-effectiveness of percutaneous coronary intervention (PCI) procedures to open blocked coronary arteries.
