Preoperative Use of Fractional Flow Reserve in CABG Use and Effectiveness of FFR-based CABG in Real-life Practice

The use of fractional flow reserve (FFR) to guide coronary artery bypass graft (CABG) is controversial and not ubiquitously adopted across the units. There is no definitive evidence that the use of FFR improves early clinical outcomes after CABG, with the exception of a simplification of the procedure. FFR use may help in defining the indication to the use arterial grafts, but there is no evidence that preoperative FFR lead to any benefits in terms of patency when venous grafts are used. On these grounds a large multicentric all-comers observational study is planned. The aim is to achieve a real-life picture of the FFR practice in CABG across several European and non-European units. This study will inform on the effective use rate of FFR in the CABG practice and its clinical effectiveness when compared to standard angiography-based CABG.
