Intraoperative evaluation of coronary anastomosis by transit-time ultrasonic flow measurement Tetsuro Morota, MD, PhD, Francis G Duhaylongsod, MD, William R Burfeind, MD, Ching-Tsorng Huang, MD The Annals of Thoracic Surgery Volume 73, Issue 5, Pages 1446-1450 (May 2002) DOI: 10.1016/S0003-4975(02)03505-1

Fig 1 Diagram of the procedure. The left internal thoracic artery (LITA) is anastomosed to the left anterior descending artery (LAD), which is occluded just proximal to the first diagonal branch. An adjustable occluder (Occ) and a flow probe (Pr) are placed on the graft. The Annals of Thoracic Surgery 2002 73, 1446-1450DOI: (10.1016/S0003-4975(02)03505-1)

Fig 2 Representative receiver operating characteristic curves. (A) Diastolic/total flow ratio, which showed the highest area under the curve (AUC) value. (B) Diastolic flow, which showed the second highest area under the curve value. The Annals of Thoracic Surgery 2002 73, 1446-1450DOI: (10.1016/S0003-4975(02)03505-1)
