• Background Limited study has detailed the late‐term safety and efficacy of chronic total coronary occlusion (CTO) revascularization among multiple centers applying modern techniques and with newer‐generation drug‐eluting stents. Methods Among 20 centers, 222 patients enrolled in the XIENCE coronary stent, performance, and technique (EXPERT) CTO trial underwent CTO percutaneous coronary intervention (PCI) with everolimus‐eluting stents (EES). Through planned 4‐year follow‐up, the primary composite endpoint of major adverse cardiac events (MACE; death, myocardial infarction [MI] and target lesion revascularization) and rates of individual component endpoints and stent thrombosis were determined. Results Demographic, lesion, and procedural characteristics included prior bypass surgery, 9.9%; diabetes, 40.1%; lesion length, 36.1 ± 18.5 mm; and stent length, 51.7 ± 27.2 mm. By 4 years, MACE rates were 31.6 and 22.4% by the pre‐specified ARC and per‐protocol definitions, respectively. Clinically‐indicated target lesion revascularization at 4 years was 11.3%. In landmark analyses of events beyond the first year of revascularization, the annualized rates of target vessel‐related MI and clinically‐indicated target lesion revascularization were 0.53 and 1.3%, respectively. Through 4 years, the cumulative definite/probable stent thrombosis rate was 1.7% with no events occurring beyond the initial year of index revascularization. Conclusions In a multicenter registration trial representing contemporary technique and EES, these results demonstrate sustained long‐term safety and effectiveness of EES in CTO percutaneous revascularization and can be used to inform shared decision making with patients being considered for CTO PCI relative to late safety and vessel patency.
