Background: The study aimed to report the results from an all-comers registry of patients undergoing coronary angioplasty and treated with bioresorbable vascular scaffold (BVS).
Methods: Fifty-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.
Results: The 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.
Conclusions: The 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.
