Treatment of Moderate Vein Graft Lesions With Paclitaxel Drug Eluting Stents: The VELETI Trial

2014-08-27 03:46:11 | BioPortfolio

Summary

HYPOTHESIS

1. Sealing moderate SVG lesions with the TAXUS stent prevents SVG atherosclerosis progression as evaluated by IVUS.

2. Sealing moderate SVG lesions with the TAXUS stent does not accelerate SVG atherosclerosis in the angiographically non-diseased segments of the SVG as evaluated by IVUS.

OBJECTIVES

1. 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.

2. 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.

Description

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.

Medical and Biotech [MESH] Definitions

Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.

Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.

Coronary artery bypass surgery on a beating HEART without a CARDIOPULMONARY BYPASS (diverting the flow of blood from the heart and lungs through an oxygenator).

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.

Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization.
