Brief summary
This prospective, multicenter, single-arm, interventional study evaluates the effectiveness and safety of Medipixel XA-Assisted Percutaneous Coronary Intervention (MPXA-PCI) in patients with coronary artery disease (CAD). The study aims to assess procedural success rates and clinical outcomes associated with the novel MPXA-assisted PCI strategy in a real-world clinical setting. A total of 830 patients with de novo coronary lesions eligible for drug-eluting stent (DES) implantation will be enrolled. All participants will undergo MPXA-assisted lesion assessment to optimize balloon and stent selection. The primary outcome is target vessel failure (TVF) at 12 months, defined as a composite of cardiac death, target vessel-related myocardial infarction, and clinically driven target vessel revascularization. Secondary outcomes include procedural success, angiographic results, and periprocedural complications. This study will provide evidence regarding the clinical applicability and safety of artificial intelligence-assisted quantitative coronary analysis (AI-QCA) technology for optimizing PCI procedures.
Interventions
Medipixel XA-Assisted Percutaneous Coronary Intervention (MPXA-PCI) is an AI-assisted coronary intervention procedure utilizing Medipixel XA (MPXA), an artificial intelligence-based quantitative coronary analysis (AI-QCA) software. MPXA analyzes angiographic images in real-time to assist in lesion assessment, optimal balloon and stent selection, and procedural decision-making during percutaneous coronary intervention (PCI). In this study, all participants will undergo MPXA-assisted PCI, where the software provides automated vessel segmentation, diameter measurement, and lesion quantification to optimize procedural outcomes. Operators will follow a predefined protocol incorporating MPXA measurements for balloon sizing, stent selection, and post-dilation strategies. The study evaluates the safety, feasibility, and clinical impact of MPXA-assisted PCI in real-world coronary artery disease patients.
