Identification of ischemia-causing lesions using coronary plaque quantification and changes in fractional flow reserve derived from computed tomography across the lesion
Abstract:Background: This study sought to evaluate the association between coronary plaque characteristics, changes in the fractional flow reserve (FFR) derived from computed tomography across the lesion (ΔFFR CT ), and lesion-specific ischemia using the FFR in patients with suspected or known coronary artery disease.
Methods:The study assessed coronary computed tomography (CT) angiography stenosis, plaque characteristics, ΔFFR CT , and FFR in 164 vessels of 144 patients. Obstructive stenosis was defined as stenosis ≥5… Show more
