Key result
Intraoperative flow measured in well-functioning coronary bypass grafts by pulsed Doppler technique did not influence early postoperative clinical outcome.

No influence on early outcomes; leaves open Doppler utility beyond well-functioning grafts in prospective studies.

Does intraoperative Doppler flow measurement in coronary bypass grafts predict early postoperative clinical outcome in patients undergoing isolated coronary artery surgery?
p-value: p=NS
Intraoperative Doppler flow measurements in well-functioning bypass grafts do not predict early postoperative clinical outcomes, which are instead driven by preoperative clinical condition and cardiopulmonary bypass duration.
Louagie et al. (1994) conducted an observational in Isolated coronary artery surgery (n=352). Flow in bypass grafts measured by pulsed Doppler technique was evaluated on Early postoperative clinical outcome (normal, complicated, or poor) (p=NS). Intraoperative flow measured in well-functioning coronary bypass grafts by pulsed Doppler technique did not influence early postoperative clinical outcome.
