CTA, computed tomography angiography; CTO, chronic
total occlusion; RCA, right coronary artery.
Consequently, there is substantial interest in using novel imaging methods for preprocedural characterization of chronic
total occlusion.
Chronic
total occlusion, a complete blockage of the coronary artery, sometimes referred to as the «final frontier in interventional cardiology,» represents a major challenge for catheter - based percutaneous coronary intervention (PCI).
