Highlights and essentials from the first "experts-live" course of the EuroCTO club
2010
Chronic total occlusions (CTOs) are frequently encountered during diagnostic coronary catheterisation. However, there is still confusion regarding the indication for percutaneous coronary intervention (PCI) in this lesion subset, mainly because it is cumbersome and the prognostic impact of revascularisation in these patients remains unclear. Many studies have now shown the long term clinical benefits after CTO PCI1-3; still, with procedural complexity, high radiation exposure to both the patient and the operator, high costs and lower procedural success rates, most patients with CTO are managed medically or referred for bypass graft surgery – regardless of the severity of symptoms and extent…
Differences in patients and lesion and procedure characteristics depending on the age of the coronary chronic total occlusion
2018
Introduction: Whether duration of chronic total occlusion (CTO) affects lesion and procedural characteristics remains largely unknown. Aim: To investigate whether CTO duration influences lesion characteristics and revascularization success. Material and methods: EuroCTO Registry data on patients who had CTO percutaneous coronary intervention between January 2015 and April 2017 were analyzed. Three groups were created based on occlusion age: 3 to 6 months (n = 1415), 7 to 12 months (n = 973), > 12 months (n = 1656). Results: Patients with greater CTO duration were older (63.0 (56.0–70.0); 63.0 (56.0–71.0); 66.0 (59.0–73.0) years respectively; p < 0.001), had more 3-vessel disease (32.2…

Chronic total coronary occlusions and the Occluded Artery Trial. A critical appraisal.
2008
The OAT trial and its angiographic substudy TOSCA-2, along with a number of published commentaries, represents examples of over-interpretation of clinical study results. A study that achieved no statistically significant result for any of the study endpoints can only claim to have proven that their null hypothesis cannot be rejected. The lack of power due to a reduction of patient numbers by one third, and an unexpected low event rate, makes it not unlikely that another trial would be able to disprove the null hypothesis. These statistical facts should be accepted by the authors and commentators. Instead, the inconclusive results were interpreted in such a way that they might apply to patie…
Derivation and Validation of a Chronic Total Coronary Occlusion Intervention Procedural Success Score From the 20,000-Patient EuroCTO Registry
2019
Abstract Objectives The aim was to establish a contemporary scoring system to predict the outcome of chronic total occlusion coronary angioplasty. Background Interventional treatment of chronic total coronary occlusions (CTOs) is a developing subspecialty. Predictors of technical success or failure have been derived from datasets of modest size. A robust scoring tool could facilitate case selection and inform decision making. Methods The study analyzed data from the EuroCTO registry. This prospective database was set up in 2008 and includes >20,000 cases submitted by CTO expert operators (>50 cases/year). Derivation (n = 14,882) and validation (n = 5,745) datasets were created to develop a …
