TCT 2025: iCABG Study Comparing iFR Versus Angiography Guided CABG
This news is covered by the Medical Dialogues Bureau at the TCT Conference 2025 in San Francisco, USA.
Using instantaneous wave-free ratio (iFR) to guide coronary artery bypass grafting (CABG) significantly improved graft patency while reducing the number of grafts required, compared with angiography-guided surgery, according to three-year results from the iCABG randomized trial.
The iCABG study, presented by Dr. Rasa Ordienė of the Lithuanian University of Health Sciences at TCT 2025, is a prospective, randomized, single-blind trial evaluating whether physiology-guided surgical revascularization can optimize graft outcomes in patients with multivessel coronary artery disease (CAD).
Author's summary: Improved graft patency with iFR-guided CABG.
