The aim of the study was to compare acute and long‐term angiographic and clinical outcome of balloon angioplasty and elective stenting in de novo lesions in the body of a saphenous vein graft (SVG). A total of 150 patients, with de novo lesions in SVG, were randomly assigned to balloon angioplasty or elective Wiktor I stent implantation. The angiographic restenosis rate at 6‐month follow‐up was 32.8% in the balloon group and 19.1% in the stent group ( P = 0.069). At 1‐year follow‐up, target vessel revascularization rate was 31.4% vs. 14.5% ( P < 0.05), and event‐free survival was 60.0% vs. 76.3% ( P < 0.05) for the balloon and stent group, respectively. Elective stent implantation in de novo SVG lesions is associated with a significant lower target vessel revascularization rate and a significant higher event‐free survival at 1‐year follow‐up as compared to balloon angioplasty.
