Using Intraoperative Coronary Bypass Graft Imaging to Improve Graft Patency (GRIIP)
Coronary Disease
About this trial
This is an interventional prevention trial for Coronary Disease focused on measuring coronary disease, angiography, intraoperative care, vascular patency
Eligibility Criteria
Inclusion Criteria: isolated aortocoronary bypass surgery left ventricular ejection fraction >20% expect at least 2 bypass grafts Exclusion Criteria: renal insufficiency (creatinine >180 umol/L) known allergy to indocyanine green contrast dye severe peripheral vascular disease precluding femoral access known allergy to radiographic contrast media women of childbearing potential co-morbid illness which precludes the use of follow-up angiography geographically inaccessible for follow-up angiography
