This review demonstrates real-time visualization improves procedural success in coronary chronic total occlusion PCI, suggesting the integration of advanced imaging technologies.
Coronary chronic total occlusions (CTOs) are diagnosed in a significant portion of patients undergoing coronary angiography and represent one of the most complex scenarios in contemporary percutaneous coronary interventions (PCI). This review systematically examines how adjunctive imaging modalities’—intravascular ultrasound (IVUS), optical coherence tomography (OCT), and coronary computed tomography angiography (CCTA)—co-registration enhances the precision and success rates of CTO-PCI during the procedure. The strategic integration of these technologies enables the development of patient-specific intervention strategies tailored to individual vascular architecture and lesion characteristics. This personalized approach marks a transition from standardized protocols to precision interventional cardiology, potentially optimizing procedural success rates while minimizing complications.
