Why the study?
The study was conducted to ascertain the patency of bypass grafts during off-pump CABG surgery using intraoperative transit time flowmetry.
Does intraoperative transit time flowmetry (TTFM) effectively identify unsatisfactory graft patency requiring correction in patients undergoing off-pump CABG?
Population

Supports intraoperative graft assessment in off-pump CABG; leaves open randomized validation of TTFM thresholds.
Does intraoperative transit time flowmetry (TTFM) effectively identify unsatisfactory graft patency requiring correction in patients undergoing off-pump CABG?
Intraoperative transit time flowmetry is a logistically simple and effective method for assessing graft patency during off-pump CABG, allowing for immediate surgical correction of unsatisfactory grafts.
