dc.description.abstractTo characterize Doppler flow patterns of the grafted left internal mammary artery (LIMA) in patients with and without dobutamine stress induced wall motion abnormalities in the graft distribution, we studied 29 patients who underwent coronary artery bypass surgery using LIMA grafts to the left anterior descending coronary artery (LAD). the ungrafted right internal mammary artery (RIMA) was used as a control. RIMA Doppler flow pattern was predominantly systolic in all patients. in patients without ischemia in the LAD distribution, LIMA flow was predominantly diastolic. in patients with ischemia, LIMA flow was predominantly systolic. in the grafted LIMA, a ratio of diastolic to systolic time-velocity integral of >1.5 best showed absence of ischemia in the graft distribution. in summary, characterization of the Doppler flow pattern in the internal mammary arteries is feasible. in the grafted LIMA, ratios of diastolic to systolic flow are less in patients with on ischemic response in the subtended vascular bed than in those without ischemia.
