A b s t r a c tBackground: The number of percutaneous coronary interventions (PCI) with bioresorbable vascular scaffolds (BVS) is increasing because these procedures offer additional benefits compared to PCI with classical drug eluting stents (DES) made of permanent metallic prostheses.Aim: To present the current experience of using BVS in a real life scenario in patients with stable coronary artery disease (CAD), with a special focus on the assessment of safety and effectiveness of the hybrid strategy (single stage BVS and DES implantation).
Methods:We performed a one-arm prospective registry, which enrolled patients with stable CAD in five interventional cardiology centres in Poland. All patients who met inclusion and exclusion criteria and had received at least one BVS stent during index PCI were included. The primary endpoint was the cumulative rate of major adverse cardiovascular events (MACE), consisting of cardiac death, myocardial infarction (MI), and clinically-driven target lesion revascularisation (TLR) at 12 months. The analysis was performed in the whole population as well as in the subgroup with the hybrid treatment (BVS + DES).Results: Between August 2013 and April 2014 139 patients were enrolled. The mean age was 59.5 ± 5.5 years, and 34.5% of the population were women. The target vessel was located in the left anterior descending artery in most cases (65.5%). The device success rate was 100%. At 12 months, in the whole population the cumulative MACE incidence was 7.2% (n = 10), while the clinically-driven TLR rate was 5.0% (n = 7). In further analysis, in the hybrid subgroup there was no death, MI, or stent thrombosis, and only one case of clinically-driven TLR (4.5%).
Conclusions:The obtained data enable us to say that in particular clinical scenarios the simultaneous use of BVS and DES might be safe and effective.
628INTRODUCTION Drug-eluting stents (DES) have greatly improved outcomes of percutaneous coronary intervention (PCI) by managing the issue of excessive neointimal growth. However, the permanent presence of the metallic platform and the durable polymer might impair the natural healing process of the coronary vessel wall and lead to a prolonged inflammatory response as well as untoward clinical outcomes [1,2].Recently, PCI with bioresorbable vascular scaffolds (BVS) has emerged as an interesting alternative because the presence of the prosthesis (the scaffold as well as the polymer with the drug) in the coronary artery is temporary. Moreover, this novel technology enables restoration of the normal vessel reactivity and facilitates positive remodelling. As a consequence, it reduces the trigger for persistent inflammation and enables further interventions by percutaneous or surgical means [3].Also, the hybrid use of BVS and classical DES is a novel approach. This strategy can be applied to reduce the costs of PCI for very long lesions but also to avoid certain limitations of currently available Absorb BVS ® stents. The customisation (sizes and lengths) of BVS at the time of the study wa...
