A comparison of transit-time flowmetry and intraoperative fluorescence imaging for assessing coronary artery bypass graft patency.

BACKGROUND: Intraoperative graft patency assessment during coronary artery bypass grafting enables detection and immediate correction of graft failure. Currently transit-time flowmetry is used to assess graft patency on the basis of mean graft flow and derived values, such as the pulsatility index....
