Background: Previous randomized controlled trials demonstrated a higher rate of stent thrombosis with bioresorbable vascular scaffold (BVS) implantation as compared with second-generation drug-eluting stent in selected patients/lesions. However, long-term outcomes of BVS implantations that utilize an optimized technique (OIT) in unselected patients/lesions are lacking. The aim of this study was to assess the real-world, long-term clinical outcomes of BVS (Absorb; Abbott Vascular) with OIT.

Methods and results: In a cohort of 156 patients, a total of 347 BVS devices (435 lesions) were implanted, with intravascular ultrasound (IVUS) guidance utilized in 303 (87.3%) of the scaffolds. The primary efficacy endpoint was target-lesion revascularization (TLR) and the primary safety endpoint was scaffold thrombosis. Despite performing routine high-pressure postdilation, postintervention IVUS detected BVS und...
