The CT-PLAN PCI trial will evaluate whether CCTA-guided PCI improves procedural efficiency compared with routine PCI (without pre-procedural CCTA-guidance for PCI planning) using procedural time as the primary endpoint. Key secondary outcomes will include contrast volume, radiation dose, fluoroscopy time, resource utilization, and periprocedural outcomes including post-PCI physiology, and peri-procedural myocardial injury measured by high-sensitivity cardiac troponin assays.
CCTA provides comprehensive anatomical characterization of coronary arteries, including plaque morphology. It allows assessment of the origin and course of the coronaries, proximal and distal reference vessel dimensions, which can inform landing zones for stent length selection, and stent sizing. CCTA also enables comprehensive physiological assessment through fractional flow reserve (FFRCT), including FFRCT pullback for disease pattern characterization and delta FFRCT. In addition, CCTA can estimate vessel-specific myocardial mass to support bifurcation PCI planning and may assist intra-proce…
Inclusion Criteria: * At least one moderate-severe coronary stenosis on CCTA with an FFRCT ≤0.80 involving no more than two vessels (i.e. target lesion(s) must be FFRCT eligible) * Referral for non-emergent PCI of at least one de novo stenosis in a native coronary artery with a reference diameter ≥2 mm on CCTA. Exclusion Criteria: * Multivessel CAD involving ≥3 vessels. * Severe left main disease \>50% * Prior CABG * Prior PCI in target vessel * Planned CABG * Chronic coronary total occlusion in the target vessel * ST-elevation myocardial infarction * Emergent PCI * Cardiac arrest * Cardiog…
Participants randomized to CT-guided PCI will have their clinically available CCTAs analyzed using commercially available software to create a pre-procedural plan, which will be used to help guide the procedure
Participants randomized to routine PCI will not have their CCTA's analyzed pre-procedure. The investigator may use intravascular imaging and pre-PCI FFR, but these are not mandated. The investigator will use the information obtained from the coronary angiogram to treat any coronary artery disease that is present.
