Filter by:A considerable number of patients presented with anatomically successful PCI results still suffer from functionally unresolved ischemia, which might be the cause for over one-fourth of patients experiencing recurrent angina at 1 year or adverse events at 2 years. Currently, the post-PCI physiology measurement is one of the effective metrics to quantify residual ischemia, and a suboptimal post-PCI result is strongly associated with worse outcomes. However, PCI optimization based on post-PCI physiology is, to certain extent, a provisional rescue action for a suboptimal index procedure, which may not be fully correctable "after the fact" given selected stents, site of deployment and procedural technique. Computed tomography (CT) coronary physiology-derived virtual stenting (CT-VS) based on pre-PCI CCTA angiograms is an augmented reality (AR) approach that simulates the post-stenting physiology assuming that the specified segment of the treated vessel is successfully dilated by implanting virtual stents. Previous studies have demonstrated the feasibility of optimizing PCI with CT-VS, with high consistency between pre-PCI simulated physiology result by CT-VS and actual post-PCI physiology results. Therefore, the application of CT-VS would help physicians to develop the best strategies while planning the procedure. However, there is a lack of knowledge regarding the efficacy of this novel physiological index that is available pre-PCI in achieving final post-PCI optimal physiological result. The Trials of "Computed Tomography Coronary Physiology-derived Virtual Stenting Guided Revascularization Strategy in Patients with Coronary Artery Disease (CT-COMPASS)" was designed to assess the efficacy of a CT-VS vs. standard angiographic guidance in achieving post-PCI optimal physiological result (post-PCI FFR≥0.90).
