Comparison between OPCABG and CABG Surgical Revascularization Using Transit Time Flow Measurement (TTFM)

Objective: To compare the intraoperative quality of coronary anastomoses performed with or without cardio-pulmonary bypass using transit time flow measurement (TTFM) parameters.Methods: We collected data from 588 consecutive patients who underwent surgical revascularization. We retrospectively reviewed data from two groups: 411 with cardiopulmonary bypass (CABG group) and 177 off- pump (OPCABG group). Transit time flow measurement parameters: mean graft flow (MGF), pulsatile index (PI), and diastolic filing (DF) were measured for each graft and patient.Results: Patients in the OPCABG group had higher EuroSCORE compared with the CABG group (3.53 ± 2.32 versus 2.84 ± 2.15, P = .002). Overall comparison of TTFM parameters showed no statistical difference between the two surgical techniques except for PI in circumflex artery terri-tory, which was higher in the OPCABG group for all types of grafts 3.0 ± 4.9 versus 2.4 ± 2.0 in, P = .026.Conclusion: The comparison between OPCABG and CABG in this study showed comparable results with both surgical techniques. PI was higher in the OPCABG group in harder-to-reach vessel territories. Measurement of transit time may improve the quality, safety, and efficacy of coro-nary artery bypass grafting and should be considered as a routine procedure.
