Figure 1. Intraoperative setup for epicardial high-resolution ultrasonography. The black arrow shows the epicardial ultrasonography probe; the white arrows show the foot pods of the stabilizer, where the distal anastomosis must be stabilized during high-resolution ultrasonography to reduce image motion artifacts; and the yellow arrow shows the left internal thoracic artery graft to the left anterior descendent coronary artery (A). Image obtained through intraoperative epicardial high-resolution ultrasonography with doppler flow measurement. The orange arrow shows the anastomosis; the yellow arrow depicts flows in native vessel distal to the anastomosis; and the black hatched arrow depicts flows in the native vessel proximal to the anastomosis (B).
