FFR Cutoff by Arterial Graft Configuration and Location: IMPAG Trial Insights

The use of fractional flow reserve (FFR) to guide coronary artery bypass grafting surgery (CABG) is controversial, but recent data from the IMPAG (Impact of Preoperative FFR on Arterial Bypass Graft Function) trial [(1)][1] suggest that pre-operative FFR closely correlate with 6-month arterial
