Pulsed Doppler flowmetry in the intraoperative evaluation of coronary grafts. It is still necessary?
2024, Cirugia CardiovascularThe predictive value of intraoperative transit-time flow measurement parameters for early graft failure in different target territories
2021, Journal of CardiologyCitation Excerpt :The probable explanation might be that MGF did not decrease significantly until graft stenosis was greater than 75%, the single MGF may be not a good parameter to predict early graft failure [18]. The PI value is regarded as a good predictor of graft quality in both our and previous studies, however the cut-off value to detect early graft failure (3 months to 1 year) has been suggested to be 3 or 5 [19,20]. The results of our study found that the PI value was also a predictor in earlier (before discharge) graft failure.
Intraoperative Graft Patency Verification in Coronary Artery Surgery: Modern Diagnostic Tools
2009, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :Although FFT analysis could be a good base for automated flow curves interpretation in the future, at the present there are no cutoff values to guide graft revision. Although ultrasound-based Doppler technology was initially proposed to monitor anastomosis quality after surgical myocardial revascularization,21 its wide application has been limited by the introduction of TTFM technology on the market. Recently, it has been shown that the performance of a newly designed dual-beam Doppler flowmeter compared favorably with TTFM.22

2006, Journal of Thoracic and Cardiovascular SurgeryImproving the quality of coronary bypass surgery with intraoperative angiography: Validation of a new technique
2005, Journal of the American College of CardiologyCitation Excerpt :Difficulties incorporating bulky equipment into the cardiac operating room and safety concerns regarding nephrotoxicity and embolic/bleeding complications have limited implementation of intraoperative X-ray angiography. Graft assessment techniques such as thermal angiography, Doppler flow measurement, and electromagnetic flow measurement have also been attempted in the operating room with limited success (9–12). More recently, transit-time ultrasound flow measurement has gained significant implementation, particularly in off-pump coronary surgery.
