Pre-procedural coronary computed tomography angiography (CTA) can identify calcification, tortuosity and accurately determine the occlusion length, which may facilitate chronic total occlusion (CTO) crossing. A major limitation of offline CTA is lack of real-time guidance during percutaneous coronary intervention (PCI). This limitation can be overcome using CTA co-registration with real-time fluoroscopy system.
