Brief Summary
Context: Sirolimus-eluting-stents have improved the benefits of percutaneous interventions in native coronary arteries reducing the occurrence of restenosis and repeated revascularization, however saphenous vein grafts have been always excluded form randomized trials. Objective: To evaluate the angiographic and clinical impact of sirolimus-eluting-stents with respect to bare-metal-stents in degenerated vein grafts. Design: Double-blind randomized controlled non-industry-sponsored trial. Setting: A single-center tertiary-care referral hospital. Patients: All patients are randomly allocated to sirolimus-eluting-stent implantation or the corresponding bare-metal-stent. All patients are followed clinically and repeated angiographic follow-up is performed in all at 6-months. Main outcome measure: Primary end-point is 6-months angiographic in-stent late loss. Secondary end-points include: binary angiographic in-stent and in-segment restenosis, intravascular-ultrasound-measured neo-intimal hyperplasia volume and all the clinical events (death, myocardial infarction, target-lesion and target-vessel revascularization).

- clear signs and/or symptoms of stable or unstable angina or documented silent ischemia
- one or more de-novo target lesions (\>50% diameter stenosis by visual estimate) localized in one or more diseased SVG with a reference vessel diameter (RVD) included between 2.5 and 4.0 mm (by visual estimate)
- signed informed consent.
You may not qualify if:
- Myocardial Infarction within the previous 7 days
- documented left ventricular ejection fraction \<25%
- impaired renal function (creatinine \>3.0 mg/dl) at the time of treatment
