Abstract

Aims: Bioresorbable vascular scaffolds (BVS) present different mechanical properties as compared to metallic platform sterns. Therefore, the standard procedural technique to achieve appropriate deployment may differ. Methods and results: Fifty-two lesions treated with a 3x18 mm BVS were imaged with optical coherence tomography (OCT) post-implantation and screened for parameters suggesting non-optimal deployment. These included minimal scaffold area (rninSA)<5 mm(2), residual area stenosis (RAS)>20%, edge dissections, incomplete scaffold/strut apposition (ISA)>5% and scaffold pattern irregularities. The angiographic proximal and distal maximal lumen diameters (DMAX) were measured by quantitative coronary angi Conclusions: BVS implantation guided with quantitative angiography may improve the OCT findings of optimal deployment. The clinical significance of these angiographic and OCT findings warranted long term follow-up of larger cohort of patients.
