Abstract
OBJECTIVES To examine the success and complication rates in percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) caused by in-stent restenosis (ISR). BACKGROUND PCI for in-stent total occlusive disease has traditionally been associated with low success rates. We sought to examine angiographic and procedural outcomes of patients who underwent CTO PCI due to ISR using the novel "hybrid" algorithm, and compare them with patients with de novo CTOs. METHODS We examined 521 consecutive patients who underwent CTO PCI at five high-volume PCI centers in the United States using the "hybrid" approach. Clinical, angiographic, and procedural outcomes were compared between CTOs due to ISR and de novo CTOs. RESULTS The target CTO was due to ISR in 57 of 521 patients (10.9%). Compared to patients with de novo CTOs, those with CTO due to ISR had higher frequency of diabetes (56.1% vs. 39.6%, P = 0.02) and less calcification (5.3% vs. 16.2%, P <0.001), but longer occlusion length [38 (29-55) vs. 30 (20-51), P = 0.04]. Technical success in the ISR and de novo group was 89.4% and 92.5% (P = 0.43), respectively; procedural success was 86.0% and 90.3% (P = 0.31), respectively; and the incidence of major adverse cardiac events was 3.5% and 2.2% (P = 0.63), respectively. CONCLUSIONS Use of the "hybrid" approach to CTO PCI was associated with similarly high procedural success and similarly low major complication rates in patients with de novo and ISR CTOs.

Abstract
A paucity of data is available from large-scale studies evaluating the long-term outcomes of percutaneous coronary intervention in patients who had previously undergone coronary artery bypass grafting (CABG) in the drug-eluting stent era. Of 12,812 patients who had undergone sirolimus-eluting stent implantation in the j-Cypher registry, 919 (7.2%) had a history of CABG and had significantly higher crude 5-year mortality (19.9% vs 14.0%, p <0.001). After adjusting for confounders, the excess risk of death was no longer significant (hazard ratio 0.99, 95% confidence interval 0.83 to 1.18, p = 0.90), and the adjusted risk of target lesion revascularization was significantly higher in patients with previous CABG than in those without (hazard ratio 1.25, 95% confidence interval 1.06 to 1.47, p = 0.01). Of the patients with previous CABG, those who had undergone ≥1 saphenous vein graft intervention had significantly higher adjusted risks of cardiac death (hazard ratio 2.21, 95% confidence interval 1.26 to 3.76, p = 0.01), myocardial infarction (hazard ratio 2.56, 95% confidence interval 1.10 to 5.60, p = 0.03), target lesion revascularization (hazard ratio 2.65, 95% confidence interval 1.82 to 3.81, p <0.001), and definite stent thrombosis (hazard ratio 7.70, 95% confidence interval 1.99 to 29.1, p = 0.004) compared with those who underwent percutaneous coronary intervention only for the native coronary artery. In conclusion, the adjusted mortality was similar between patients with and without previous CABG, despite a significantly different risk of target lesion revascularization. Among the patients with previous CABG, those with saphenous vein graft intervention using a first-generation drug-eluting stent had worse clinical outcomes than those with a native coronary artery target only.

Abstract
BACKGROUND Patients with prior coronary artery bypass graft surgery (CABG) who present with an acute coronary syndrome have a high risk for recurrent events. Whether intensive antiplatelet therapy with ticagrelor might be beneficial compared with clopidogrel is unknown. In this substudy of the PLATO trial, we studied the effects of randomized treatment dependent on history of CABG. METHODS Patients participating in PLATO were classified according to whether they had undergone prior CABG. The trial's primary and secondary end points were compared using Cox proportional hazards regression. RESULTS Of the 18,613 study patients, 1,133 (6.1%) had prior CABG. Prior-CABG patients had more high-risk characteristics at study entry and a 2-fold increase in clinical events during follow-up, but less major bleeding. The primary end point (composite of cardiovascular death, myocardial infarction, and stroke) was reduced to a similar extent by ticagrelor among patients with (19.6% vs 21.4%; adjusted hazard ratio [HR], 0.91 [0.67, 1.24]) and without (9.2% vs 11.0%; adjusted HR, 0.86 [0.77, 0.96]; P(interaction) = .73) prior CABG. Major bleeding was similar with ticagrelor versus clopidogrel among patients with (8.1% vs 8.7%; adjusted HR, 0.89 [0.55, 1.47]) and without (11.8% vs 11.4%; HR, 1.08 [0.98, 1.20]; P(interaction) = .46) prior CABG. CONCLUSIONS Prior-CABG patients presenting with acute coronary syndrome are a high-risk cohort for death and recurrent cardiovascular events but have a lower risk for major bleeding. Similar to the results in no-prior-CABG patients, ticagrelor was associated with a reduction in ischemic events without an increase in major bleeding.

Abstract
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 < 0.001), had a higher Charlson Comorbidity Index (P = 0.004), and presented more often with acute coronary syndrome (P = 0.02). At 3-year follow-up, cardiac death occurred in 9.7% versus 2.1% (P < 0.001), myocardial infarction (MI) in 8.3% versus 3.0% (P = 0.02), target lesion failure in 13.9% versus 6.4% (P = 0.03), and major adverse cardiac event in 18.1% versus 8.6% (P = 0.01). No differences were observed in TV-MI and TLR, nor stent thrombosis (ST) which was generally low in both groups (1.4% vs 0.8%, P = NS). CONCLUSION Albeit 3-year outcomes were less favorable in the CABG group, the higher cardiac mortality was apparently not driven by ST, target vessel MI, or TLR, but is likely due to advanced disease and age as well as comorbidity. The low TLR rate as well as the absence of late and very late ST suggest that BES are safe and effective for the treatment of CABG lesions.

Abstract
AIM Thrombosis of stents and of saphenous vein grafts (SVG) remains a severe complication of either revascularization techniques that often are present as ST elevation myocardial infarction (STEMI). The aim of this longitudinal cohort study was to compare the 1-year clinical outcomes among STEMI patients requiring primary PCI due to stent thrombosis and graft occlusion presenting with STEMI. METHODS AND RESULTS We prospectively collected data on all patients undergoing primary PCI at the Montreal Heart Institute between April 1, 2007 and March 30, 2008. Study patients were grouped according to the etiology of the STEMI: stent thrombosis, graft thrombosis, or atherosclerosis-related STEMIs (control group). The primary combined end-point, major adverse cardiac events (MACE), was defined as death, myocardial infarction, and target vessel revascularization within 12 months as primary end point. Of the 489 STEMI patients included in the study, 23 were due to stent thrombosis, 22 to graft thrombosis, and 444 in the control group. Stent and graft thromboses were associated with a higher MACE rates, 26.1 and 22.7%, respectively, compared to the control group, 9.3% (P = 0.004). Moreover, only stent thrombosis was associated with an increased risk of MACE (HR 2.57, confidence interval 95% 1.08-6.08. CONCLUSION Patients with stent thrombosis present with higher rate of reinfarction while graft thrombosis is associated with an increase in 1-year cardiac mortality. Using multivariate analysis, higher MACE rates were associated with stent thrombosis as compared to graft thrombosis.

Abstract
Saphenous vein grafts (SVGs) are prone to an aggressive atherosclerotic process, and the efficacy of drug-eluting stents (DES) in treating this is still debated. In recent years, second-generation DES have been increasingly used in SVG intervention. The main objective of this study was to compare midterm clinical outcomes between first- and second-generation DES in SVGs because data regarding the use of second-generation DES in SVG are lacking. Patients treated with first-generation DES (127 patients with 143 lesions) and those treated with second-generation DES (84 patients with 100 lesions) were included in the study. Major adverse cardiac events, defined as the composite of all-cause death, myocardial infarction, and target vessel revascularization, as well as target vessel revascularization and target lesion revascularization separately, were evaluated at 30-day, 12-month, and 18-month follow-up. Baseline characteristics were similar between the 2 groups. Older grafts were treated with second-generation DES (11.6 ± 5.3 vs 14.3 ± 6.0 years, p = 0.001). Stent length was longer in the first-generation group (34.1 ± 25.1 vs 30.5 ± 19.4 mm, p = 0.006), and maximum balloon diameter was smaller in the second-generation group (3.42 ± 0.42 vs 3.30 ± 0.41 mm, p = 0.003). Embolic protection device use was higher in the second-generation DES group (55.2% vs 72.0%, p = 0.012). At 18-month follow-up, rates of major adverse cardiac events, target vessel revascularization, and target lesion revascularization for the first- and second-generation groups were 24.4% versus 20.2% (p = 0.479), 18.1% versus 14.2% (p = 0.465), and 15.0% versus 10.7% (p = 0.373), respectively. In conclusion, second-generation DES are at least comparable with first-generation DES with regard to clinical outcomes at midterm follow-up.

Abstract
Coronary artery bypass graft surgery remains one of the most widely performed surgical procedures in North America and aortocoronary saphenous vein grafts (SVG) are the most frequently used surgical conduits. SVG disease (SVGD) remains the leading cause of symptomatic coronary artery disease postcoronary artery bypass graft. When optimal medical therapy is ineffective, repeat surgery is associated with higher mortality combined with less favorable clinical and angiographic results, thus percutaneous revascularization on SVG is currently the standard of care for the revascularization of SVGD. Balloon angioplasty, bare metal stents, polytetrafluoroethylene-covered stents, and drug-eluting stents have been extensively investigated for SVG interventions. Multiple recent randomized trials and meta-analyses have confirmed the pathophysiologic and clinical differences between SVGD and coronary artery disease. Decisions such as patient selection, premedication, stent, and protection device characteristics should be carefully considered to achieve optimal procedural and clinical results. Acute coronary syndromes due to SVG involvement, chronic total occlusions, retrograde approaches, and SVG perforation management are newer fields requesting additional research.

Abstract
OBJECTIVE To review our current understanding of the epidemiology and pathogenesis of vein graft failure (VGF), give an overview of current preventive and interventional measures, and explore strategies that may improve vein graft patency. BACKGROUND VGF and progression of native coronary artery disease limit the long-term efficacy of coronary artery bypass graft surgery. METHODS We reviewed the published literature on the pathophysiology, prevention, and/or treatment of VGF by searching the MEDLINE (January 1, 1966-January 1, 2012), EMBASE (January 1, 1980-January 1, 2012), and Cochrane (January 1, 1995-January 1, 2012) databases. In addition, we reviewed references from the selected articles for studies not identified in the initial search. Basic science and clinical studies were included; non-English language publications were excluded. RESULTS Acute thrombosis, neointimal hyperplasia, and accelerated atherosclerosis are the 3 mechanisms that lead to VGF. Preventive measures include matching and quality assessment of conduit and target vessel, lipid-lowering drugs, antithrombotic therapy, and cessation of smoking. Treatment of VGF includes medical therapy, percutaneous intervention, and redo coronary artery bypass graft surgery. In patients undergoing graft intervention, the use of drug-eluting stents, antiplatelet agents, and embolic protection devices may improve clinical outcomes. CONCLUSIONS Despite advances in management, VGF remains one of the leading causes of poor in-hospital and long-term outcomes after coronary artery bypass graft surgery. New developments in VGF prevention such as gene therapy, external graft support, fully tissue-engineered grafts, hybrid grafts, and synthetic conduits are promising but unproven. Future efforts to reduce VGF require a multidisciplinary approach with a primary focus on prevention.

Abstract
Percutaneous coronary intervention (PCI) of saphenous vein graft (SVG) is associated with higher adverse event rates, lower procedural success, and inferior longterm patency rates compared with native vessel PCI. The ability to comply with dual antiplatelet therapy, and whether the patient will need an interruption in dual antiplatelet therapy, should be considered when deciding whether to implant a drug-eluting stent (DES) or bare metal stent (BMS) in an SVG. DES should be used for SVG PCI because they seem to reduce target vessel revascularization. This article reviews the evolution and contemporary evidence regarding use of DES versus BMS in SVG PCI.

Abstract
Percutaneous interventions of (usually degenerated) saphenous vein grafts (SVG) are associated with higher risk of distal embolization and worse clinical outcomes, including target vessel revascularization, myocardial infarction, and death, as compared with percutaneous coronary intervention of native coronary arteries. Embolic protection devices have demonstrated value in reducing the risk of embolization and postprocedural enzyme elevation after SVG interventions. Frequently, however, such devices are not used or cannot be used. As a result, novel stenting strategies intended to decrease the risk of periprocedural myocardial infarction seem to play a major role in enhancing the results following SVG interventions.

Abstract
CABG surgery is an effective way to improve symptoms and prognosis in patients with advanced coronary atherosclerotic disease. Despite multiple improvements in surgical technique and patient treatment, graft failure after CABG surgery occurs in a time-dependent fashion, particularly in the second decade after the intervention, in a substantial number of patients because of atherosclerotic progression and saphenous-vein graft (SVG) disease. Until 2010, repeat revascularization by either percutaneous coronary intervention (PCI) or surgical techniques was performed in these high-risk patients in the absence of specific recommendations in clinical practice guidelines, and within a culture of inadequate communication between cardiac surgeons and interventional cardiologists. Indeed, some of the specific technologies developed to reduce procedural risk, such as embolic protection devices for SVG interventions, are largely underused. Additionally, the implementation of secondary prevention, which reduces the need for reintervention in these patients, is still suboptimal. In this Review, graft failure after CABG surgery is examined as a clinical problem from the perspective of holistic patient management. Issues such as the substrate and epidemiology of graft failure, the choice of revascularization modality, the specific problems inherent in repeat CABG surgery and PCI, and the importance of secondary prevention are discussed.

Abstract
BACKGROUND Long-term safety and efficacy data of drug-eluting stents (DESs) in saphenous vein grafts (SVGs) are lacking. This study sought to compare the clinical outcomes of DES versus bare metal stents (BMS) in SVGs. METHODS We studied all stent implantations in SVGs in Sweden during 74 months between 2005 and 2011 registered in the Swedish Coronary Angiography and Angioplasty Registry. We evaluated outcome in patients who received DES compared with those who received BMS after adjustments for differences in clinical, vessel, and lesion characteristics. RESULTS Mean follow-up time was 3 years and 4 months. A total of 4,576 stents, implanted at 3,063 procedures, were included in the analysis of which 2,499 stents (54.6 %) were BMS and 2,077 (45.4%) were DES. The outcome analysis was based on 190 stent thromboses, 898 restenoses, and 523 deaths. The incidence of stent thrombosis did not differ between groups. When adjusted for baseline characteristics, including a propensity score for receiving DES, the incidence of restenosis was significantly lower with DES as compared with BMS (risk ratio 0.83, 95% CI 0.70-0.97, P = .019). There was a difference in mortality in the crude analysis between DES and BMS, and after multivariable adjustment, this difference remained statistically significant (risk ratio 0.80, CI 0.65-0.99, P = .038). CONCLUSIONS The use of DES compared with BMS in SVGs was associated with a significantly lower adjusted incidence of restenosis and death in this large, national, all-encompassing propensity adjusted observational study.

Abstract
Neointimal hyperplasia (NIH) in bypass conduits such as veins and prosthetic grafts is an important clinical entity that limits the long-term success of vascular interventions. Although the development of NIH in the conduits shares many of the same features of NIH that develops in native arteries after injury, vascular grafts are exposed to unique circumstances that predispose them to NIH, including surgical trauma related to vein handling, hemodynamic changes creating areas of low flow, and differences in biocompatibility between the conduit and the host environment. Multiple different approaches, including novel surgical techniques and targeted gene therapies, have been developed to target and prevent the causes of NIH. Recently, the PREVENT trials, the first molecular biology trials in vascular surgery aimed at preventing NIH, have failed to produce improved clinical outcomes, highlighting the incomplete knowledge of the pathways leading to NIH in vascular grafts. In this review, we aim to summarize the pathophysiologic pathways that underlie the formation of NIH in both vein and synthetic grafts and discuss current and potential mechanical and molecular approaches under investigation that may limit NIH in vascular grafts.

Abstract
BACKGROUND Clinical outcomes of percutaneous coronary intervention (PCI) in patients with saphenous vein grafts (SVGs) remain poor despite the use of drug-eluting stents (DES). There is a disparity in clinical outcomes in SVG PCI based on various registries, and randomized clinical data remain scant. We conducted a meta-analysis of all existing randomized controlled trials (RCTS) comparing bare-metal stents (BMS) and DES in SVGPCIs. HYPOTHESIS PCI in patients with SVG disease using DES may reduce need for repeat revascularization without an excess mortality when compared to BMS. METHODS An aggregate data meta-analysis of clinical outcomes in RCTs comparing PCI with DES vs BMS for SVGs reporting at least 12 months of follow-up was performed. A literature search between Janurary 1, 2003 and September 30, 2011 identified 4 RCTs (812 patients; DES = 416, BMS = 396). Summary odds ratio (OR) and 95% confidence interval (CI) were calculated using the random-effects model. The primary endpoint was all-cause mortality. Secondary outcomes included nonfatal myocardial infarction (MI), repeat revascularization, and major adverse cardiac events (MACE). These outcomes were assessed in a cumulative fashion at 30 days, 18 months, and 36 months. RESULTS There were no intergroup differences in baseline clinical and sociodemographic characteristics. At a median follow-up of 25 months, patients in the DES and BMS group had similar rates of death (OR: 1.63, 95% CI: 0.45-5.92), MI (OR; 0.83, 95% CI: 0.27-2.60), and MACE (OR: 0.58, 95% CI: 0.25-1.32). Patients treated with DES had lower rates of repeat revascularization (OR: 0.40, 95% CI: 0.22-0.75). CONCLUSIONS In this comprehensive meta-analysis of all RCTs comparing clinical outcomes of PCI using DES vs BMS in patients with SVG disease, use of DES was associated with a reduction in rate of repeat revascularization and no difference in rates of all-cause death and MI.

Abstract
We evaluated the incidence of clinical events after implantation of the TAXUS Liberté paclitaxel-eluting stent in saphenous vein graft (SVG) lesions in an unselected patient population. The OLYMPIA (TAXUS Liberté Post-Approval Global Registry) program gathered data on 21 954 patients receiving at least 1 TAXUS Liberté stent, including 345 patients with SVG lesions. All cardiac events were monitored with independent adjudication of end points. Patients enrolled at procedure started with no mandated inclusion/exclusion criteria. In SVG-OLYMPIA (n = 345), baseline comorbidities/complex disease were more frequent than the rest of the OLYMPIA (n = 21 560). SVG-OLYMPIA had similar cardiac death, target vessel revascularization, and definitive stent thrombosis rates than the rest of OLYMPIA. Despite higher baseline risk, the SVG-OLYMPIA had similar 12-month clinical outcome than the rest of the OLYMPIA registry, confirming the safety and efficacy of the TAXUS Liberté stent in this high-risk group.

Abstract
Saphenous vein grafts are commonly used conduits for surgical revascularization of coronary arteries but are associated with poor long-term patency rates. Percutaneous revascularization of saphenous vein grafts is associated with worse clinical outcomes including higher rates of in-stent restenosis, target vessel revascularization, myocardial infarction, and death compared with percutaneous coronary intervention of native coronary arteries. Use of embolic protection devices is a Class I indication according to the American College of Cardiology/American Heart Association guidelines to decrease the risk of distal embolization, no-reflow, and periprocedural myocardial infarction. Nonetheless, these devices are underused in clinical practice. Various pharmacological agents are available that may also reduce the risk of or mitigate the consequences of no-reflow. Covered stents do not decrease the rates of periprocedural myocardial infarction and restenosis. Most available evidence supports treatment with drug-eluting stents in this high-risk lesion subset to reduce angiographic and clinical restenosis, although large, randomized trials comparing drug-eluting stents and bare-metal stents are needed.

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
BACKGROUND Comparative assessment of clinical outcomes after use of drug-eluting stents versus bare-metal stents for treatment of aortocoronary saphenous vein graft lesions has not been undertaken in large randomised trials. We aimed to undertake a comparison in a randomised trial powered for clinical endpoints. METHODS In this randomised superiority trial, patients with de-novo saphenous vein graft lesions were assigned by computer-generated sequence (1:1:1:3) to receive either drug-eluting stents (one of three types: permanent-polymer paclitaxel-eluting stents, permanent-polymer sirolimus-eluting stents, or biodegradable-polymer sirolimus-eluting stents) or bare-metal stents. Randomisation took place immediately after crossing of the lesion with a guidewire, and was stratified for each participating centre. Investigators assessing data were masked to treatment allocation; patients were not masked to allocation. The primary endpoint was the combined incidence of death, myocardial infarction, and target lesion revascularisation at 1 year. Analysis was by intention to treat. This trial is registered at ClinicalTrials.gov, number NCT00611910. FINDINGS 610 patients were allocated to treatment groups (303 drug-eluting stent, 307 bare-metal stent). Drug-eluting stents reduced the incidence of the primary endpoint compared with bare-metal stents (44 [15%] vs 66 [22%] patients; hazard ratio [HR] 0.64, 95% CI 0.44-0.94; p=0.02). Target lesion revascularisation rate was reduced by drug-eluting stents (19 [7%] vs 37 [13%] patients; HR 0.49, 95% CI 0.28-0.86; p=0.01). No significant differences were seen between drug-eluting stents and bare-metal stents regarding all-cause mortality (15 [5%] vs 14 [5%] patients; HR 1.08, 95% CI 0.52-2.24; p=0.83), myocardial infarction (12 [4%] vs 18 [6%]; HR 0.66, 95% CI 0.32-1.37; p=0.27), or definite or probable stent thrombosis (2 [1%] in both groups; HR 1.00, 95% CI 0.14-7.10; p=0.99). INTERPRETATION In patients undergoing percutaneous coronary intervention for de-novo saphenous vein graft lesions, drug-eluting stents are the preferred treatment option because they reduce the risk of adverse events compared with bare-metal stents.

Abstract
AIMS PCI with drug eluting stents (DES) has been shown to reduce restenosis and major adverse cardiac event (MACE) rates compared to bare metal stents (BMS) in native coronary vessels, although outcomes in saphenous vein graft (SVG) lesions are less clear. We retrospectively studied 388 consecutive patients admitted to our centre for SVG PCI to assess mortality and MACE outcomes (defined as composite endpoint of all-death, stroke, myocardial infarction, stent thrombosis and target lesion (TLR)/vessel (TVR) revascularisation) associated with BMS and DES use. METHODS AND RESULTS Two hundred and nineteen (219) patients had BMS and 169 had DES (total 388 patients). Mean follow up was 41.9±23.5 months. No significant differences were observed in mortality (14.2% vs. 11.8%) or MACE (37.6% vs. 35.8%) between the BMS and DES groups at four years follow-up or at other intervening time points studied. Similarly, no differences in TVR/TLR rates were observed over a similar time period (19.8% vs. 21.6%). CONCLUSIONS We have observed that DES and BMS use in SVG PCI have comparable mortality and MACE rates, and that in contrast to PCI in native coronary arteries, DES do not reduce revascularisation rates in our study cohort.

Abstract
Contemporary management of coronary artery disease relies increasingly on percutaneous techniques combined with medical therapy. Although percutaneous coronary intervention (PCI) can be performed successfully in most lesions, several difficult lesion subsets continue to present unique technical challenges. These complex lesions may be classified according to anatomic criteria, including extensive calcification, thrombus, and chronic occlusions, or by location, such as bifurcations, saphenous vein grafts and unprotected left main. PCI of these lesions often requires novel devices, such as drug-eluting stents, hydrophilic guidewires, distal protection balloons or filters, thrombectomy catheters, rotational atherectomy, and cutting balloons. An integrated approach that combines these devices with specialized techniques and adjunctive pharmacologic agents has greatly improved PCI success rates for these complex lesions.
