- Abstract
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%; 30.9%; 46.1% respectively; p < 0.001) and more frequent prior coronary artery bypass grafting (8.2%; 9.9%; 29.4% respectively; p < 0.001). In multivariate analysis, occlusion duration was associated with moderate/ severe calcification (OR = 1.52; 95% CI: 1.28-1.80; p < 0.001), lesion length > 20 mm (OR 1.77; 95% CI 1.49-2.10; p < 0.001), and collateral circulation Werner type 2 (OR = 1.20; 95% CI: 1.01-1.43; p = 0.041). The CTO duration was associated with lower procedural success (OR for success 0.60; 95% CI: 0.46-0.79; p < 0.001). In multivariate analysis in-hospital adverse events did not differ according to duration of CTO. Conclusions: Coronary artery CTO duration is associated with greater extent of calcification, lesion length, development of collateral circulation and, most importantly, with lower procedural success.
