Transit-time flow measurement is a valuable intraoperative tool during CABG for assessing graft patency and flow characteristics.
Transit-time flow measurement (TTFM) has been increasingly applied to detect graft failure during coronary artery bypass grafting (CABG), because TTFM is less invasive, more reproducible, and less time consuming. Many authors have attempted to validate TTFM and to gain the clear cutoff values and algorithm in TTFM to predict graft failure. The TTFM technology has also been shown to be a useful tool to investigate CABG graft flow characteristics and coronary circulation physiology. It is important to recognize the practical roles of TTFM in the cardiac operating room by review and summarize the literatures.

Takagi et al. (2018) conducted a review in Coronary artery bypass grafting (CABG). Transit-time flow measurement (TTFM) was evaluated. Transit-time flow measurement (TTFM) serves as a useful, less invasive, and reproducible tool to detect graft failure and investigate coronary circulation physiology during coronary artery bypass surgery.
