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…

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…

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…

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…

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…

The identification of vulnerable plaques has been a longstanding challenge for interventional cardiologists. Plaque composition is regarded as an important feature for assessment of plaque vulnerability. Histopathologists have in particular shown that the type of plaque most commonly prone to rupture in vivo is the thin-cap fibroatheroma (TCFA), in which the presence of lipid core (also called…

Proceedings of two satellite symposia held at EuroPCR, Paris in May 2015
Although the latest polymeric drug-eluting stents (DES) have enhanced percutaneous coronary intervention (PCI) procedures, a substantial proportion of patients requiring percutaneous transluminal coronary angiography (PTCA) is elderly with numerous different comorbidities. This population requires use of effective DES that…

Drug-eluting stents (DESs) have contributed to a significant lowering of the incidence of restenosis and target vessel revascularisation (TVR) in bifurcations.1–4 A randomised study of bifurcation lesions using sirolimus-eluting stents revealed restenosis rates of only 4 % in the main branch (MB) and a TVR rate as low as 8.2 % at six-month follow-up,2 a marked improvement over that in historical…
