Aims: Reports of long-term outcomes of patients treated with drug-eluting stents in total coronary occlusions are limited. We analysed clinical outcomes of patients treated with the zotarolimus-eluting Resolute stent (R-ZES) implanted in coronary total occlusions versus non-occluded lesions. Methods and results: Patients treated with R-ZES and included in four trials (RESOLUTE All Comers, RESOLUTE International, RESOLUTE China RCT, and RESOLUTE China Registry) were pooled and divided into three groups - patients with chronic total occlusions (CTO), patients with total occlusions that had occurred recently (rec-TO), and patients without total occlusions (non-TO). Clinical outcomes at five years were analysed. Of 5,487 patients treated with R-ZES in these trials, 8.0% had CTOs, 8.5% rec-TOs and 83.5% non-TOs. Patients had a mean age of 62.8 years, approximately 25% were female and 30% were diabetics. TLF was similar in the three groups at five years (TLF was 13.2%, 12.5% and 13.3% in the CTO, rec-TO and non-TO groups, respectively, p=0.96). Stent thrombosis tended to occur more frequently for rec-TO compared to CTO and non-TO patients (2.6% vs 1.2% and 1.3%, respectively, p=0.11). Conclusions: In this large population of patients who had R-ZES implanted, five-year clinical outcomes were similar whether or not the stents were implanted in total occlusions.
