Late Neointimal Regression 5 Years After Polymer-Free Biolimus A9-Coated Stent Implantation: A Case Report
نویسندگان
چکیده
A polymer-free biolimus A9-coated stent (PF-BCS; BioFreedom™, Biosensors Interventional Technologies, Singapore) can elute the drug even without a polymer by retaining on rough surface of wall (1). Here we present case late neointimal regression 1–5 years after percutaneous coronary intervention (PCI). We performed PCI for severe stenosis proximal right artery and implanted PF-BCS. The thickness in evaluated optical coherence tomography was 0.30±0.24 mm at 1 year but decreased to 0.17±0.09 5 PCI, indicating regression.

Polymer-free biolimus a9-coated stent demonstrates more sustained intimal inhibition, improved healing, and reduced inflammation compared with a polymer-coated sirolimus-eluting cypher stent in a porcine model.
BACKGROUND Drug-eluting stents effectively reduce restenosis but may increase late thrombosis and delayed restenosis. Persistent polymer, the drug, or a combination of both could be responsible. Local delivery of Biolimus A9, a rapamycin derivative, from a polymer-free BioFreedom stent (Biosensors International) may prevent these complications. METHODS AND RESULTS We compared high-dose (HD) (...

Objectives: To evaluate the effect of a polymer-free Biolimus A9-eluting stent [BioFreedom (BF)], compared with that of a biodegradable polymer-based Biolimus A9-eluting stent [BioMatrix Flex (BMF)] and a bare metal stent (BMS) in balloon denuded and radiated hypercholesterolemic rabbit iliac arteries. Methods: Rabbits were fed with 1% cholesterol diet (n 5 14) for 14 days, both iliac arteries ...
متن کاملBiolimus-A9 polymer-free coated stent in high bleeding risk patients with acute coronary syndrome: a Leaders Free ACS sub-study
Aims Although a true clinical challenge, high bleeding risk patients with an acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) have never been specifically studied. Leaders Free ACS, a pre-specified Leaders Free sub-study, determined efficacy, and safety of a combination of 1-month dual anti-platelet therapy (DAPT) with implantation of either a polymer-free Bioli...
متن کاملA Case of Stent Thrombosis Occurred at 5 Years after Sirolimus-Eluting Stent Implantation
Drug-eluting stents (DES) have reduced the rate of repeated revascularization of target lesions. For this reason, DES are considered to be superior to bare-metal stents in reducing the restenosis rate. However, some problems have been reported after implantation of DES. One of them, stent thrombosis, has arisen as a fatal complication. Dual antiplatelet therapy is recommended for at least 12 mo...
متن کاملVery Late Stent Thrombosis due to Neointimal Rupture After Paclitaxel-Eluting Stent Implantation
We report our experience of very late stent thrombosis (VLST) in a young male patient who underwent implantation of two paclitaxel-eluting stents (PES) six years ago. The patient was compliant with standard dual antiplatelet therapy, but he presented with acute myocardial infarction which was associated with VLST. Intravascular ultrasound showed neointimal rupture with thrombus within the PES i...
