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.
