The new flowmeter deciphers waveforms for graft patency during CABG procedures
Early graft failure after Coronary Artery Bypass Grafting (CABG) is reported in up to 12 percent of grafts. Three percent are clinically apparent and may contr
ibute to early mortality. Graft failure can be due to vessel defects, anastomotic technical errors, poor native run-off or competitive flow. Repeat revascularization, if required, is expensive and puts patients at risk.
To help cardiac surgeons identify and correct suspect grafts intraoperatively, Transonic introduces the Optima 354C Flowmeter, with automated Graft Patency Assessment. The Optima 354C analyzes graft flow, flow waveforms and pressure signals and distills these into simple graft patency feedback for the surgeon. Transonic’s proven “Flow-based Intraoperative Coronary Artery Bypass Patency Assurance” protocols are the basis for the assessment.
As the creator of transit-time ultrasound volume flow measurement, Transonic has spent decades developing expertise in flow measurement and waveform morphology and advancing flow assessment algorithms.
“Surgeons cannot be expected to be waveform morphology experts,” said Miriam Tenorio, vice president of marketing at Transonic. “The Optima 354C will do that for them and provide an easy-to-use printout with mean flow, flow profile, pressure and an assessment of graft flow patency.”
“After hours spent recreating flow with complex grafts, confirming an adequate flow rate is a valuable final step in any CABG procedure,” said Tenorio. “The Optima 354C provides an easy-to-use, objective assessment of graft patency prior to closure to help avoid preventable reoperations.”
