| Popis: | Objectives This study sought to evaluate procedural and clinical outcomes among patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using contemporary methods and everolimus-eluting stents (EES). Background Limited studies have detailed the procedural and late-term safety and efficacy of CTO revascularization among multiple centers applying modern techniques and with newer-generation drug-eluting stents. Methods Among 20 centers, 250 consecutive patients were enrolled for attempted CTO PCI. Procedural and in-hospital clinical outcomes were examined in addition to the 1-year primary endpoint of death, myocardial infarction, and target lesion revascularization (major adverse cardiac events [MACE]). 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. Procedural success, defined as guidewire recanalization with no in-hospital MACE, was 96.4%. Success with antegrade-only methods was 97.9% and 86.2% by retrograde/combined methods, respectively. Compared with a pre-specified performance goal derived from 6 prior CTO drug-eluting stent trials (1-year MACE: 24.4%), treatment with EES was associated with significantly lower composite adverse events for both intent-to-treat (18.5%, 1-sided upper confidence interval: 23.4%, p = 0.025) and per-protocol populations (8.2%, 1-sided upper confidence interval: 12.3%, p Conclusions In a multicenter registration trial representing contemporary technique and EES, favorable procedural success and late-term clinical outcomes support CTO PCI in a patient population with high lesion complexity.
