The Use of Intraoperative Transit Time Flow Measurement for Coronary Artery Bypass Surgery: Systematic Review of the Evidence and Expert Opinion Statements
Why the study?
Transit time flow measurement allows quality control in coronary artery bypass grafting but remains underused, likely due to limited information and lack of standardization.
Does intraoperative transit time flow measurement improve graft patency and clinical outcomes in patients undergoing coronary artery bypass grafting?
Comparison
TTFM and other quality control methods in coronary artery bypass grafting
Design
PRISMA systematic review and 3-step modified Delphi expert consensus panel

Implication
Supports TTFM adoption for CABG graft assessment; extends evidence with 10 expert consensus statements.
Structured PICO
Does intraoperative transit time flow measurement improve graft patency and clinical outcomes in patients undergoing coronary artery bypass grafting?
P
Population
Patients undergoing coronary artery bypass grafting (CABG)
I
Intervention
Intraoperative transit time flow measurement (TTFM)
O
Outcome
Graft patency and postoperative clinical outcomes
A systematic review and expert consensus supports the use of intraoperative transit time flow measurement during CABG to assess graft patency and improve clinical outcomes, despite increased procedural time and costs.
Limitations
- High methodological heterogeneity among published series
- Increases duration and cost of surgery
- Requires a learning curve
