Although bioresorbable polymer sirolimus-eluting Ultimaster stents (BP-SESs) are likely useful for percutaneous coronary interventions (PCIs), the clinical data from real-world cases are insufficient. Furthermore, the predictors of adverse clinical outcomes after BP-SES implantation have not been fully investigated.


This study evaluated the 1-year clinical outcomes after BP-SES implantation in real-world PCI cases and identified the predictors of adverse outcomes.


In this single-center, all-comers study, we consecutively implanted BP-SESs in all patients who required coronary stents between October 2015 and August 2016. We conducted a clinical follow-up assessment of these patients.


The sample comprised 1,727 patients; 67% were men, the mean age was 72 years, and 37% had diabetes. Of the 2,085 lesions detected, 88% were type B2/C lesions, 4% were chronic total occlusions (CTOs), and 23% were bifurcations. The cumulative incidences of target lesion revascularization (TLR) and target lesion failure (TLF) at 1-year were 2.4% and 5.2%, respectively. A multivariate analysis revealed that hemodialysis (HD) (hazard ratio [HR] 8.40) and CTO (HR 4.21) were independent predictors of TLR. Stent sizes ≤2.5 mm were not associated with either TLR or TLF.


The current study indicates that patients on HD and those with CTO were more likely to experience adverse clinical outcomes after BP-SES implantation. In contrast, small vessel diameter was not significantly related to adverse outcomes. The 1-year clinical outcomes after BP-SES implantation were found to be favorable among all-comer PCI cases, including patients receiving HD and those with in-stent restenosis.
