Brief 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.

Study Arms (2)

Virtual Stenting-Guided PCI Optimization

EXPERIMENTAL

Participants randomized to the experimental group will undergo coronary imaging-physiology fusion-based virtual stenting analysis before PCI. Predicted post-PCI physiological outcomes will be used to optimize interventional strategies, including lesion coverage, stent length, stent position, and procedural planning before stent implantation.

Procedure: Virtual Stenting-Guided PCI Optimization

Angiography-Guided PCI

ACTIVE COMPARATOR

Participants randomized to the control group will undergo PCI according to standard angiographic guidance and operator judgment without virtual stenting-guided physiological optimization.

Procedure: Standard Angiography-Guided PCI

Interventions

Conventional percutaneous coronary intervention performed according to angiographic findings and routine clinical practice without use of virtual stenting-guided physiological optimization.

Angiography-Guided PCI

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 years.
