Long-Term Follow-Up of Coronary Venous Bypass Graft Lesions Treated with a New Generation Drug-Eluting Stent with Bioabsorbable Polymer

Background To date, no published data are available regarding long-term follow-up of new generation DES implanted in coronary artery bypass graft (CABG) lesions. Objectives To assess the long-term clinical outcome of patients receiving the new generation Biolimus A9-coated drug-eluting stent (DES) with biodegradable polymer in saphenous vein grafts (SVG). Methods Three thousand sixty-seven patients were included in the NOBORI 2 registry: 71 patients with a total of 117 lesions received at least 1 biolimus A9 DES in SVG lesions and 2,959 patients received percutaneous coronary intervention in other lesions. Clinical follow-up was performed at 1, 6, and 12 months, and annually up to 3 years. Results Compared to the non-CABG group, patients with CABG lesions were older (P
