Artificial Intelligence‐Empowered Image Fusion of Coronary Computed Tomography Angiography and Invasive Angiography for Guiding Chronic Total Occlusion Percutaneous Coronary Intervention

Coronary computed tomography angiography (CCTA) provides qualitative and quantitative characteristics of atherosclerotic plaques, quantified percentages of myocardial perfusion from target vessels, and functional information-key insights that lend critical guidance to pre-percutaneous coronary intervention (PCI) planning, particularly for complex coronary interventional procedures. Advances in artificial intelligence-enabled CCTA imaging analysis and CT-angiography image fusion technology have facilitated the translation of CT imaging into clinical practice for PCI operators. This case report describes a PCI procedure for a chronic total occlusion of right coronary artery performed under the guidance of CT-coronary angiography fusion technology, serving as a practical example for the application of CCTA in pre-PCI planning for complex coronary lesions.
