To determine the effect of stenting moderate SVG lesions with the paclitaxel-eluting stent in comparison with medical treatment on limiting SVG disease progression as evaluated by IVUS.\n2. To evaluate by IVUS the effect of stenting moderate SVG lesions with the paclitaxel-eluting stent in comparison with medical treatment on atherosclerosis progression in angiographically non-diseased SVGs segments.', 'detailedDescription': 'This will be a prospective randomized study assessing the efficacy of stenting moderate SVG lesions with the taxus stent in the prevention of atherosclerosis progression of SVGs as evaluated by IVUS. Patients with previous coronary bypass surgery with SVG implantation undergoing coronary angiography by clinical indication will be screened. If the patient has a moderate lesion at any level of the SVGs it will be includable in the study. After inclusion, the patients will be randomized to either stenting the moderate SVG lesion with the taxus stent or standard medical treatment. The use of a filter wire during dilation will be strongly recommended. Following this procedure, all patients will have clinical controls at 1 month and at 6 months and an angiographic and IVUS control study at 1 year follow-up.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Written and signed informed consent.\n* Patients ≥18 years old.\n* Clinical indication for cardiac catheterization and SVG angiography.\n* Presence of at least one SVG lesion of 30% to 70% diameter stenosis by visual estimation which is (are) not the culprit lesion (s) responsible for the clinical syndrome of the patient.\n\nExclusion Criteria:\n\n* Ejection fraction \\<20%.\n* Renal insufficiency with creatinine \\> 250 mg/dl.\n* Presence of more than 3 moderate SVG stenosis or significant diffuse SVG disease.\n* Unsuccessful angioplasty (residual stenosis \\>30% and/or TIMI flow \\<3) of any other lesion treated during the same procedure.\n* Coronary angioplasty of the target SVG in the past.\n* Cardiogenic shock .\n* Remaining lesion (s) with a treatment planned within the following year.\n* Pregnancy.\n* Contraindication to aspirin and/or clopidogrel treatment.\n* Allergy to paclitaxel.\n* Any disease with a limiting life-expectancy (to less than 2 years).\n* Definite presence or high suspicion of thrombus or ulceration in the target lesion.\n* Target lesion located in the same SVG than the culprit lesion (if present) and the distance between the target lesion and the most proximal or distal part of the stent implanted at the culprit lesion is \\< 4 cm.\n* Vein graft diameter \\< 2.5 mm.'}, 'identificationModule': {'nctId': 'NCT00289835', 'acronym': 'VELETI', 'briefTitle': 'Treatment of Moderate Vein Graft Lesions With Paclitaxel Drug Eluting Stents: The VELETI Trial', 'organization': {'class': 'OTHER', 'fullName': 'Laval University'}, 'officialTitle': 'Sealing Moderate Coronary Saphenous VEin Graft LEsions With the Paclitaxel-eluting Stent (Taxus) as a New Approach to Maintain Vein Graft Patency and Reduce Cardiac Events: a Pilot Intravascular Ultrasound Study.', 'orgStudyIdInfo': {'id': 'Laval-VG-01'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'PCI-stenting', 'description': 'Stenting the moderate SVG lesion with the paclitaxel stent', 'interventionNames': ['Device: Paclitaxel eluting stent']}, {'type': 'OTHER', 'label': 'Standard medical treatment', 'interventionNames': ['Device: Paclitaxel eluting stent']}], 'interventions': [{'name': 'Paclitaxel eluting stent', 'type': 'DEVICE', 'otherNames': ['Taxus (paclitaxel eluting stent)'], 'description': 'Patients are randomized to either stenting the moderate SVG lesion with the paclitaxel stent or standard medical treatment', 'armGroupLabels': ['PCI-stenting', 'Standard medical treatment']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'G1V 4G5', 'city': 'Québec', 'state': 'Quebec', 'country': 'Canada', 'facility': 'Laval Hospital', 'geoPoint': {'lat': 46.81228, 'lon': -71.21454}}], 'overallOfficials': [{'name': 'Josep Rodes-Cabau, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Laval Hospital Research Center'}, {'name': 'Olivier F Bertrand, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Laval Hospital Research Center'}, {'name': 'Robert Delarocheliere, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Laval Hospital Research Center'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Laval University', 'class': 'OTHER'}, 'collaborators': [{'name': 'Boston Scientific Corporation', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
