We determined the effects of sealing moderate nonsignificant SVG lesions with paclitaxel-eluting stents (PES) on the prevention of SVG atherosclerosis progression.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Methods and Results\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    Patients with at least 1 moderate SVG lesion (30% to 60% diameter stenosis) were randomized either to stenting the moderate SVG lesion with a PES (n=30, PES group) or to medical treatment alone (n=27, medical treatment group). Patients had an angiographic and intravascular ultrasound evaluation of the SVG at baseline and at 12-month follow-up. The primary end points were (1) the ultrasound SVG minimal lumen area at follow-up and (2) the changes in ultrasound atheroma volume in an angiographically nondiseased SVG segment. Mean time from coronary artery bypass grafting was 12\u00b16 years, and mean low-density lipoprotein cholesterol level was 73\u00b131 mg\/dL. A total of 70 moderate SVG lesions (39\u00b17% diameter stenosis) were evaluated. Significant disease progression occurred in the medical treatment group at the level of the moderate SVG lesion (decrease in minimal lumen area from 6.3\u00b13.0 to 5.6\u00b13.1 mm\n                    <jats:sup>2<\/jats:sup>\n                    ;\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001), leading to a severe flow-limiting lesion or SVG occlusion in 22% of the patients compared with none in the PES group (\n                    <jats:italic>P<\/jats:italic>\n                    =0.014).

There were no cases of restenosis or stent thrombosis. No significant atherosclerosis progression occurred at the nonstented SVG segments. At 12-month follow-up, the cumulative incidence of major adverse cardiac events related to the target SVG was 19% in the medical treatment group versus 3% in the PES group (\n                    <jats:italic>P<\/jats:italic>\n                    =0.091).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Conclusions\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    Stenting moderate nonsignificant lesions in old SVGs with PES was associated with a lower rate of SVG disease progression and a trend toward a lower incidence of major adverse cardiac events at 1-year follow-up compared with medical treatment alone, despite very low low-density lipoprotein cholesterol values.
