Temporal trends in chronic total occlusion interventions in Europe: 17626 procedures from the European Registry of Chronic total occlusion
2018
Background: The study focuses on the evolution of practice, procedural outcomes, and in-hospital complications of chronic total occlusion percutaneous coronary intervention in Europe. Methods and Results: Data from 17 626 procedures enrolled in European Registry of Chronic Total Occlusion between January 2008 and June 2015 were assessed. The mean patient age was 63.9±10.9 years; 85% were men. Procedural success increased from 79.7% to 89.3% through the study period. Patients enrolled during the years had increasing comorbidities and lesion complexity (J-CTO score [Multicenter CTO Registry of Japan] increased from 1.76±1.03 in 2008 to 2.17±0.91 in 2015; P for trend, <0.001). Retrograde a…

Dual lumen microcatheters for recanalisation of chronic total occlusions: A EuroCTO Club expert panel report
2021
Dual lumen microcatheters (DLMC) have become indispensable tools in the setting of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Other than allowing preservation and treatment of bifurcated coronary branches within or in the proximity of the CTO-body, they enable the use of modified parallel wiring, antegrade dissection and re-entry, collateral selection and retrograde negotiation of the distal CTO-cap. This Euro-CTO consensus document describes current DLMCs and suggests a practical guide to anatomies and techniques in which these devices are applicable.

Utility of Intravascular Ultrasound in Percutaneous Revascularization of Chronic Total Occlusions
2016
Intravascular ultrasound has been used for >20 years to guide percutaneous coronary intervention in different subsets of coronary lesions. During the last decade, the interest in percutaneous coronary intervention for chronic total occlusion (CTO) has increased dramatically, leading to high success rates. Failure of guidewire crossing is the most common reason for failed CTO attempts. Certain angiographic features, such as blunt proximal CTO cap, tortuosity, heavy calcification, and lack of visibility of path in the distal vessel, increase procedural difficulty. A better understanding of the behavior of the guidewire within the CTO segment may represent a key issue to achieve successful …
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 …
