Background: We previously reported that the 1-year survival-free from target lesion revascularization was 97.4% in patients with chronic total occlusion (CTO) treated with sirolimus-eluting stents (SES). There are currently no long-term results of the efficacy of SES in this subset of lesions. We assessed the 3-year clinical outcomes of 147 patients with CTO treated with either SES or bare metal stents (BMS). Methods and Results: A total of 147 (BMS = 71, SES = 76) patients were included. Four patients died in the BMS group while five patients died in the SES group, P = 0.8; two myocardial infarctions occurred in both groups, P = 0.9; and target vessel revascularization was performed in nine patients in the BMS and seven in the SES group, P = 0.5. The cumulative event-free survival of MACE was 81.7% in BMS group and 84.2% in SES group, P = 0.7. Two patients of the SES group had a coronary aneurism at 3-year angiographic follow-up. Conclusions: The use of SES was no longer associated with significantly lower rates of target vessel revascularization and major adverse cardiac events in patients with CTOs after 3 years of followup compared with BMSs.
