Chronic Total Coronary Artery Occlusion Recanalisation with Percutaneous Coronary Intervention — Single Centre 10-Year Experience

2018

Abstract Coronary artery chronic total occlusions (CTO) are common — approximately one-third of patients with significant coronary artery disease on angiography have at least 1 CTO. Invasive treatment of these lesions still remain a major challenge for interventional cardiology due to their complexity. Historically, success rates have improved to about 60–70% by using only the traditional antegrade approach. The results have dramatically improved during the last decade after more widespread application of new retrograde techniques. The aim of our study was to review and analyse single hospital experience in CTO invasive treatment and to evaluate the long-term results. A total of 519 patient…

Percutaneous Coronary Revascularization for Chronic Total Occlusions A Novel Predictive Score of Technical Failure Using Advanced Technologies

2016

Objectives The aims of this study were to describe the 10-year experience of a single operator dedicated to chronic total occlusion (CTO) and to establish a model for predicting technical failure. Background During the last decade, the interest in percutaneous coronary interventions (PCIs) of chronic total occlusions (CTOs) has increased, allowing the improvement of success rate. Methods One thousand nineteen patients with CTO underwent 1,073 CTO procedures performed by a single CTO-dedicated operator. The study population was subdivided into 2 groups by time period: period 1 (January 2005 to December 2009, n = 378) and period 2 (January 2010 to December 2014, n = 641). Observations were ra…

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry

2022

Objectives: The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Background: Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood. Methods: A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry. Results: In calendar years 2018 and 2019, 2,364 retrograde CTO PCI cases constituted the primary analysis cohort. A primary retrograde strategy was used in 1,953…

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.

TCT-16 Patient and Procedural Characteristics and In-Hospital Outcomes Associated With the Use of Retrograde Recanalization Techniques for Chronic To…

2016

Since the introduction of the Hybrid Algorithm for Chronic Total Occlusion (CTO) PCI, the use of retrograde recanalization techniques has become more common. We sought to identify patient and procedural characteristics necessitating use of retrograde CTO techniques using a multicenter, adjudicated,

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…

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…

2016

Coronary chronic total occlusions (CTOs) are prevalent and the development of the hybrid approach to CTO PCI has been associated with increased technical success rates. However, the incidence and predictors of adverse events (AEs) during CTO PCI remains poorly defined. We analyzed baseline patient
