An investigation into the intraoperative assessment of coronary artery bypass graft patency using intraoperative fluorescence imaging and transit time flowmetry

Intraoperative graft failure contributes to cardiac morbidity and mortality after coronary artery bypass grafting (CABG). This results in perioperative myocardial infarction which is detectable in up to 9% of patients following arterial grafts and off pump CABG, but these are more technically demanding and emphasise the need for intraoperative assessment of graft patency and quality.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
