AIM: Aim of the study was to report on the feasibility and early safety and efficacy of Absorb everolimus-eluting bioresorbable vascular scaffold (BVS) for coronary artery bifurcations (CABs) treatment at a single high-volume center.
METHODS: All patients treated with Absorb implantation at our institution from March 2013 to March 2014 were enrolled in the prospective, single-center, ongoing, all-comers registry, which has the main purpose of evaluating the safety and efficacy of Absorb implantation in unselected patients treated in daily practice. In-hospital and at follow-up clinical outcomes of 46 patients undergoing treatment with Absorb in 46 CAB lesions were reported in the present study.
RESULTS: Treated CAB lesions involved the left main in 13.0% of cases, the left anterior descending artery in 65.0%, the left circumflex in 19.6%, and the right coronary artery in 2.2%. Bifurcations were classified as true (47.8%) and non-true (52.2%) according to the Medina classification. The provisional and the two-BVS techniques were used in 78.3% and 21.7%, respectively. Two-BVS techniques included: mini-crush 13.0%; reverse culotte 2.2%; T-stenting 2.2%; and V-stenting 4.3%. No in-hospital adverse events occurred. At 6 months no adverse events occurred. Only one case of target lesion revascularization was observed at day 227. No stent thrombosis occurred during follow-up.
CONCLUSION: Our preliminary experience suggested that CABs treatment with Absorb is feasible and associated with promising immediate and short-term clinical outcomes. However, larger studies with long-term follow-up are needed to adequately address the safety and efficacy of BVS use in CABs.
