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…

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…

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…

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…

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…

What considerations must be made when screening chronic total occlusion patients undergoing PCI, and how can CT be used in daily practice?
In this month's episode of ECR Podcast, Dr Vinoda Sharma, (Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK) and Dr Abdul Mozid, (Leeds Teaching Hospitals NHS Trust, Leeds, UK) discuss the ways in which CT coronary angiography can be utilised…

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…

Saphenous vein grafts (SVGs), despite their inherent inferiority to arterial conduits, still remain the type of grafts most commonly used during coronary artery bypass grafting (CABG).1 The natural and post-interventional biological behaviour of SVGs differ from that of native coronary vessels, increasing the risk of restenosis.2 SVG disease after CABG is a strong predictor of mortality.3 In a…
