Definition and Prevalence
Nowadays it is widely accepted to define chronic total occlusions (CTOs) of the coronary artery as lesions with thrombolysis in myocardial infarction 0 flow for more than three months (either angiographically proven or with high clinical likelihood).1 Occlusions of less than four weeks following an acute infarction are defined as acute or subacute and occlusions of…

Definition and Prevalence
Chronic coronary occlusions (CTOs) are defifined as lesions with Thrombolysis in Myocardial Infarction (TIMI) 0 flow older than three months (either angiographically proven or with high clinical likelihood). 1 According to a recent Canadian registry, CTOs are detected in about 30 % of patients with symptomatic coronary artery diseases (CAD).2 Likewise a very large German…

Coronary chronic total occlusions (CTOs) remain one of the most challenging percutaneous challenges in interventional cardiology, with technical success rates of only ~50–70 %.1,2 This lesion subset often poses the greatest risk and often requires techniques and equipment not typically utilised for more acute coronary lesions. However, successful percutaneous CTO revascularisation is associated…

Radial vs Femoral Access
In recent years several large registries and randomised controlled trials have demonstrated a mortality benefit for trans-radial over trans-femoral percutaneous coronary intervention (PCI), likely mediated by reduced bleeding complications.1–4 Building on the pioneering Japanese experience, the advent of the hybrid algorithim approach, coupled with innovative new…

Section A
Techniques for Chronic Total Occlusions Revascularisation
Access Route, Guiding Catheter Selection and Contralateral Injection
The femoral approach is the preferred access route by most operators. However, the radial approach might be chosen because of severe peripheral vascular disease, operator’s preference or for contralateral injection. The guiding principle of access selection is…

Coronary chronic total occlusions (CTOs) are identified in up to one third of patients with coronary artery disease referred for nonurgent coronary angiography,1,2 with an incidence increasing with age.3 Conceptually, you may argue that the motivation to reopen a totally blocked artery is not as strong as for subocclusive lesions, that have the potential to progress and cause acute events. The…

There has been rapid development in the techniques used for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) over the past decade, with success rates in experienced centres now exceeding 90%.1 This is in part due to advances in devices and techniques for CTO crossing, but also an improved understanding of strategy. The development of the ‘hybrid algorithm’ has improved…
