May aid intraoperative CABG error detection; leaves open whether routine use improves outcomes.
Does a transit-time ultrasonic flow measurement system accurately assess graft flow and detect technical errors in patients undergoing CABG?
Intra-operative transit-time ultrasonic flow measurement is an accurate tool for assessing CABG quality and detecting correctable technical errors during surgery.
