Bioresorbable coronary stent for the treatment of complex coronary lesions: Data from an all-comer registry

Abstract

BackgroundThe study aimed to report the results from an all-comers registry of patients undergoing coronary angioplasty and treated with bioresorbable vascular scaffold (BVS). MethodsFifty-five consecutive patients with type B/C coronary lesions according to the AHA classification and treated with BVS were enrolled in the study. The clinical and procedural characteristics of enrolled patients were recorded. Fifty-five consecutive subjects with coronary lesions type B/C treated with everolimus eluting stent (EES) were used as control group. ResultsThe incidence of adverse events was not statistically significant comparing subjects treated with BVS with those treated with EES. Non significant differences were also found in the follow-up considering the presence of diabetes, multivessel disease, use of more than one stent at the same time, diagnosis (STEMI vs UA/NSTEMI), use of coronary stents in overlapping.The differences were significant considering the type of lesion (Log-Rank p<0.05), stenoses treated in correspondence of a coronary bifurcation (p<0.05), the SYNTAX score (cut off 22) (p<0.001); after multivariable correction for age and gender, however, differences remained significant only for SYNTAX score. ConclusionsThe use of BVS in an all-comers registry of patients undergoing coronary angioplasty on complex coronary lesions is associated with a safety profile comparable to that obtained with EES; the use of BVS in particular conditions, such as very high SYNTAX score, should be further assessed.
