AIMS: CENTURY II is a prospective, multicentre, randomised, single-blind trial comparing the bioresorbable polymer sirolimus-eluting Ultimaster® stent (BP-SES) with the permanent polymer everolimus-eluting XIENCE stent (PP-EES). Here we present a pre-specified analysis of safety and efficacy outcomes in a subgroup of patients with small vessel coronary artery disease. METHODS AND RESULTS: CENTURY II included 525 patients with lesions of reference diameter ≤2.5 mm. Treatment was randomly assigned: 277 patients received BP-SES (399 lesions) and 248 patients received PP-EES (377 lesions). The primary outcome was target lesion failure (TLF), which is a composite of cardiac death, target vessel-related myocardial infarction (MI) and target lesion revascularisation (TLR). There was no significant difference between treatment groups in baseline or procedural data. Mean pre-procedural reference diameter was similar (BP-SES 2.30±0.40 mm, PP-EES 2.31±0.42 mm, p=0.59). Stented length was 24.0±11.7 mm for BP-SES and 23.5±11.5 mm for PP-EES (p=0.45). At 12 months, there was no significant difference between the BP-SES and PP-EES groups in TLF (6.9% vs. 7.7%; p=0.72), cardiac death (1.1% vs. 1.2%; p=0.90), target vessel MI (1.8% vs. 3.2%; p=0.30), TLR (4.0% vs. 5.7%; p=0.37), or definite or probable stent thrombosis (0.7% vs. 1.2%; p=0.57). CONCLUSIONS: In the large-scale, randomised CENTURY II trial, use of BP-SES and PP-EES for the treatment of small vessel coronary artery disease resulted in similar outcomes at 12 months.
