Virtual Stenting Based on Fractional Flow Reserve Derived from Computed Tomography in Predicting Post-Percutaneous Coronary Intervention Functional Outcomes: A Retrospective Cohort Study.

ABSTRACT: With the advancement of fractional flow reserve (FFR) derived from computed tomography (FFR_CT), virtual stenting technology has gradually developed. This study investigated the performance of virtual stenting based on FFR_CT in predicting post-percutaneous coronary intervention (PCI) FFR. Data from 75 patients (78 blood vessels) was collected retrospectively. We randomly allocated the participants to discovery (n = 26) and validation (n = 52) cohorts. The FFR_CT was calculated using pre-PCI coronary computed tomography angiography images. Virtual stent implantation was simulated using blinded and non-blinded virtual stenting methods to obtain post-virtual stenting FFR_CT. The median FFR_CT before PCI and invasive FFR were 0.7
