Abstract
AIMS To compare the intravascular ultrasonography (IVUS) findings between saphenous vein grafts (SVG) treated with paclitaxel-eluting stents (PES) vs. bare metal stents (BMS) in the Stenting Of Saphenous Vein Grafts (SOS) trial. METHODS AND RESULTS Of the 80 SOS trial patients, 38 had both baseline and follow-up IVUS examination and were included in this substudy: 17 patients received 28 BMS in 26 lesions and 21 patients received 30 PES in 28 lesions. Quantitative IVUS analysis was performed to determine the volume of in-stent neointimal hyperplasia (NIH) - defined as the difference between stent volume and lumen volume in the stented segments. Baseline characteristics were similar between patients who did and did not undergo baseline and follow-up IVUS. Patients receiving BMS and PES had similar stent and lumen volumes immediately after stenting. At 12-month follow-up, compared to BMS, PES-treated lesions had significantly less NIH volume (3.4 vs. 21.9 mm³, p<0.001) and neointima hyperplasia progression (1.6 vs. 17.1 mm³, p<0.001). No significant differences were seen in the 5 mm segment proximal and distal to the stent. CONCLUSIONS Compared to BMS, use of PES in SVG lesions is associated with significantly lower NIH formation, which may help explain the improved clinical outcomes with PES in these lesions.

Abstract
AIMS Although half of saphenous vein grafts (SVGs) present obstructive atherosclerotic disease 10 years after implantation, controversy remains concerning the ideal treatment. Our aim was to compare percutaneous revascularization (PCI) options in SVG lesions, according to intervention strategy and type of stent. METHODS A retrospective single-center analysis selected 618 consecutive patients with previous bypass surgery who underwent PCI between 2003 and 2008. Clinical and angiographic parameters were analyzed according to intervention strategy - PCI in SVG vs. native vessel vs. combined approach - and type of stent implanted - drug-eluting (DES) vs. bare-metal (BMS) vs. both. A Cox regressive analysis of event-free survival was performed with regard to the primary outcomes of death, myocardial infarction (MI) and target vessel failure (TVF). RESULTS During a mean follow-up of 796±548 days the rates of death, MI and TVF were 10.9%, 10.5% and 29.5%, respectively. With regard to intervention strategy (74.4% of PCI performed in native vessels, 17.2% in SVGs and 8.4% combined), no significant differences were seen between groups (death p=0.22, MI p=0.20, TVF p=0.80). The type of stents implanted (DES 83.2%, BMS 10.2%, both 3.2%) also did not influence long-term prognosis (death p=0.09, MI p=0.11, TVF p=0.64). The implantation of DES had a favorable impact on survival (p<0.001) in the subgroup of patients treated in native vessels but not in SVG. CONCLUSIONS Among patients with SVG lesions, long-term mortality, MI and TVF were not affected by intervention options, except for the favorable impact on survival of DES in patients treated in native vessels.

Abstract
OBJECTIVES This study compares outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients undergoing saphenous vein graft (SVG) intervention. BACKGROUND The safety and efficacy of DES in patients undergoing SVG intervention is controversial. METHODS The STENT (Strategic Transcatheter Evaluation of New Therapies) registry is a multicenter U.S. registry evaluating outcomes with DES. Our study population includes patients undergoing PCI of SVG lesions with DES (n = 785) or BMS (n = 343) who completed 9-month or 2-year follow-up. Outcomes were adjusted with propensity analyses. RESULTS The DES patients had fewer emergent procedures but had smaller vessels and longer lesions. The DES patients had less death or myocardial infarction at 9 months (hazard ratio [HR]: 0.52, 95% confidence interval [CI]: 0.33 to 0.83, p = 0.006) and less death at 2 years (HR: 0.60, 95% CI: 0.36 to 0.98, p = 0.041). Target vessel revascularization (TVR) was less with DES at 9 months (7.2% vs. 10.0%, HR: 0.36, 95% CI: 0.22 to 0.61, p < 0.001) but was no different by 2 years (18.3% vs. 16.9%, p = 0.86), although adjusted TVR rates were lower (HR: 0.60, 95% CI: 0.40 to 0.90, p = 0.014). The DES reduced TVR at 9 months in SVG lesions with diameter <3.5 mm (8.0% vs. 17.2%, p = 0.013) but not >or=3.5 mm (6.0% vs. 6.6%, p = 0.74). CONCLUSIONS Treatment of SVG lesions with DES vs. BMS is effective in reducing TVR at 9 months, although most of this advantage is lost at 2 years. The DES seem safe with less death or myocardial infarction, although selection bias might have affected these results. Our data suggest that DES might have short-term advantages over BMS in SVG lesions with diameter <3.5 mm.

Abstract
BACKGROUND Current data show conflicting results regarding safety and efficacy of drug-eluting stents (DES) versus bare-metal stents (BMS) for treating saphenous vein grafts (SVG). Our objective was to compare DES with BMS for SVG intervention. METHODS Patients undergoing stenting with DES or BMS to SVG from January 2000 to June 2007 were included. To eliminate any unobserved bias regarding stent selection, the BMS cohort was divided into pre- and post-2003 when DES became available. Adjusted Cox analysis compared DES with pre- and post-2003 BMS patients. The primary end point was a composite of all-cause mortality, myocardial infarction, or target lesion revascularization. RESULTS Of the total 566 patients, 217 (38%) received DES, 110 (20%) received BMS post-2003, and 239 (42%) received BMS pre-2003. Median follow-up was 2.9 years (interquartile range 1.4-4.9 years). There was a trend toward lower primary end point with DES compared to post-2003 BMS (91 events, adjusted hazard ratio 0.61, 95% CI 0.35-1.07, P = .08). However, despite 179 events, DES use was not associated with lower primary end point compared with pre-2003 BMS (adjusted hazard ratio 0.61, 95% CI 0.28-1.35, P = .23). CONCLUSIONS Although DES showed a trend toward a lower primary end point when compared with BMS post-2003, this association was no longer present when DES was compared to pre-2003 BMS. These results are consistent with the preponderance of available data and indicate that unobserved bias in observational registries may explain the reported benefit of DES over BMS for treating SVG.

Abstract
OBJECTIVE To compare the procedural and clinical outcomes of prior coronary artery bypass graft surgery (CABG) patients undergoing percutaneous coronary intervention (PCI) in native arteries vs. bypass grafts. METHODS The medical and catheterization records and the angiograms of 142 consecutive prior CABG patients who underwent 165 PCI of 247 lesions at our institution between January 1, 2003, and December 31, 2006, were retrospectively reviewed. RESULTS Mean age was 66+/-10 years and 99% were men: 79 and 63 patients underwent native coronary or bypass graft PCI, respectively. Compared to patients undergoing bypass graft PCI, those undergoing native coronary artery PCI were younger (mean age 64+/-10 vs. 68+/-10 years, P=.008), more likely to present with stable angina (29% vs. 8%, P=<.001), and presented earlier after CABG (after a mean of 9+/-6 vs. 12+/-5 years, P<.01). Compared to bypass graft PCI, native coronary PCI was more likely to be performed with drug-eluting stents (88% vs. 57%, P<.001) and was associated with lower risk of no-reflow (3% vs. 24%, P<.001). After a mean follow-up of 2.5+/-1.1 years, both groups of patients had similar but high incidence of myocardial infarction, repeat PCI, and death. CONCLUSIONS Prior CABG patients undergoing native coronary artery PCI have lower procedural risk, but similar postprocedural clinical outcomes compared to patients undergoing bypass graft PCI. If feasible, native coronary arteries may be the preferred PCI target in prior CABG patients.
