QFR-Guided Virtual Stenting for Preprocedural Physiological Optimization of Percutaneous Coronary Intervention: A Randomized Controlled Trial
A Multicenter, Prospective, Randomized Controlled Trial of Preprocedural Physiological Optimization of Percutaneous Coronary Intervention Using Coronary Imaging-Physiology Fusion-Based Virtual Stenting Technology
Source: ClinicalTrials.gov · Last updated 6 Jul 2026
Brief summary (registry, in English)
Coronary angiography-guided percutaneous coronary intervention (PCI) remains the standard treatment strategy for patients with coronary artery disease; however, suboptimal post-PCI physiological outcomes remain common and are associated with adverse cardiovascular prognosis. Quantitative Flow Ratio (QFR)-based virtual stenting technology enables simulation of post-intervention coronary physiology before PCI and may facilitate individualized optimization of stent implantation strategies. This multicenter, prospective, randomized controlled trial aims to evaluate whether preprocedural physiological optimization of PCI using coronary imaging-physiology fusion-based virtual stenting technology improves clinical outcomes compared with conventional angiography-guided PCI. Eligible patients undergoing PCI for coronary artery disease will be randomized in a 1:1 ratio to either virtual stenting-guided PCI optimization or standard angiography-guided PCI. The primary endpoint is major adverse cardiovascular events (MACE), defined as a composite of all-cause death, nonfatal myocardial infarction, and ischemia-driven repeat revascularization within 1 year after PCI. Secondary endpoints include post-PCI physiological optimization, cardiovascular death or nonfatal myocardial infarction, repeat revascularization, quality of life, procedural safety, and health economic outcomes.
