Abstract:
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.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
