QFR-Guided Virtual Stenting for Preprocedural Physiological Optimization of Percutaneous Coronary Intervention: A Randomized Controlled Trial
Sponsor: China National Center for Cardiovascular Diseases
Summary
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.

Interventions
Virtual Stenting-Guided PCI Optimization
Preprocedural physiological optimization of PCI using coronary imaging-physiology fusion-based virtual stenting technology based on angiography-derived Quantitative Flow Ratio (QFR) assessment to guide stent implantation strategy.
Standard Angiography-Guided PCI
Conventional percutaneous coronary intervention performed according to angiographic findings and routine clinical practice without use of virtual stenting-guided physiological optimization.
