Physiologic assessment of moderate coronary lesions: a step towards complete revascularization in coronary artery bypass grafting

摘要

BackgroundAn accurate diagnostic assessment of coronary artery disease is crucial for patients undergoing coronary artery bypass grafting (CABG). Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) to guide complete revascularization have not been adequately studied in patients prior to CABG. We compared an anatomic to a physiologic assessment of moderate coronary lesions (40–70% stenosis) in patients referred for CABG.
