Optimal Improvement of Vein Graft Patency Long Term by the Implementation Of Novel Endoscopic Harvesting Techniques

Cardiopulmonary Research Science and Technology Institute100 enrolled

Overview

This is an observational study of lone Coronary Artery Bypass Grafting procedures with endoscopic vein graft harvesting using best harvesting practices.

This is a prospective, multi-center, non-randomized, observational study of 100 patients who will undergo routine coronary artery bypass grafting. Eligible candidates will undergo lone Coronary Artery Bypass Graft (CABG) procedures with endoscopic vein harvesting using best harvesting practices, defined as: systemic heparinization prior to vein manipulation, standardization of vein graft harvesting techniques, pressure limiting syringe and 3 month use of dual anti-platelet therapy. Patients will undergo a CT angiography at 30 days and 12 months to assess vein graft patency.

Outcomes

Primary Outcomes

Optimal Improvement of Vein Graft Patency Long Term by the Implementation of Novel Endoscopic Harvesting Techniques

To demonstrate improved vein graft patency rates at 12 months for endoscopically harvest saphenous vein grafts by employment of modifications to existing techniques in vein graft handling during harvests. Vein graft patency will be measured at 30 days post CABG and at one year post CABG as evaluated by cardiac CT angiography or cardiac catheterization.

Time frame: 12 months

Secondary Outcomes

OPTION

To develop a standardized approach for harvesting, handling and preparing vein grafts in the endoscopic approach. By capturing the following: 1. Incidence of vein graft failure at the time of initial CABG as evaluated by transit time graft flow measurements 2. Incidence of vein graft failure at post-operative day 30 as evaluated by cardiac CT angiography or cardiac catheterization 3. Incidence of vein graft failure at each interval (30 day and 12 month) as categorized by: 1. Harvested vessel 2. vein graft destinations 3. vein graft quality

Time frame: 12 months
